底涂,是環氧地坪漆施工工藝中最重要的一步,只有這一步做好了,才能夠繼續在基面上面進行下一步涂裝。所以,一般對用于環氧地坪涂裝的底漆的要求為:應與基材有良好的附著力;本身具有良好的機械強度;對底材具有良好的保護性能和不起不利的副作用;能為以后的涂層創造良好的基礎,不能含有滲入上層涂膜引起弊病的組分;更要具有良好的施工性和干燥性。

Primer is the most important step in the construction process of epoxy floor paint. Only when this step is completed can the next coating be continued on the base surface. Therefore, the general requirements for primers used in floor coating are: good adhesion with the substrate; good mechanical strength; good protection against the substrate and no adverse side effects; can create a good foundation for future coatings, can not contain the components of the defects caused by infiltration into the upper coating; Better construction and dryness.

涂布底漆時一般應注意要在表面處理以后嚴格按照規定的時間及時涂布底漆。還要根據底漆品種規定的條件在底漆干燥后規定的時間范圍內涂下一道漆。過早涂布可能引起咬底及底漆中溶劑揮發困難導致漆膜干燥時間延長‘固化不良、鼓泡等情況;涂布達遲可能引起層間附著不良,且過遲涂布易由于粉塵積累或其他污染影響表觀質量。為增加下一道涂層與底漆間的附著力,可在涂布前將底漆打磨。

Primer coating should generally pay attention to the surface treatment in strict accordance with the prescribed time and timely coating primer. A paint should also be applied within the time limit specified after the primer is dried according to the conditions stipulated in the primer. Early coating may cause underbite and difficulty in solvent evaporation in primer resulting in prolonged drying time `poor solidification, bubbling and other conditions; late coating may cause poor adhesion between layers, and late coating is easy to affect the apparent quality due to dust accumulation or other pollution. To increase adhesion between the next coating and primer, the primer can be ground before coating.

涂布底漆的方法一般可采用輥涂、刷涂和噴涂。刷涂施工效率較低,一般在邊角處施工采用。最常用的是輥涂,效率高。

Coating primers are generally made by roller coating, brush coating and spraying. Brush construction efficiency is low, usually in the corner construction. The most commonly used roller coating is highly efficient. 封閉底漆施工:

Construction of closed primer:

用刷涂、輥涂或噴涂的方法施工封閉環氧地坪漆底漆一道至兩道,兩道之間的間隔時間在8h以上,但不能大于48h。對于舊地面,應增加一道底漆。底漆施工時應注意涂布均勻,涂膜無明顯的厚度差異,防止漏涂。用輥涂法施工應注意余料堆積情況。底漆封閉不完全(漏涂)時,會發生附著不牢、涂膜起泡等現象。

Use brush, roll or spray to apply one or two closed floor primers. The interval between the two primers is more than 8 hours, but not more than 48 hours. For old ground, a primer should be added. Attention should be paid to uniform coating when priming is applied, and no obvious difference in thickness is observed to prevent leakage. Attention should be paid to the accumulation of residual materials by roller coating method. When the primer is not fully sealed (leak coating), it will cause adhesion, coating and bubbling.

1.底漆漆膜厚度根據底漆品種確定,應注意控制。表面無浮塵及松散砂粒。

1. primer paint film thickness should be determined according to primer varieties, and attention should be paid to control. There is no floating dust and loose sand on the surface.

2.含顏填料的底漆在使用前和使用過程應注意攪拌均勻

2. primer with pigments and fillers should be evenly stirred before use and during use.

3.注意遵守干燥的規范。在底涂上如涂含有強溶劑的涂料時,底漆必須干透,以免出現咬底等漆病。

3. pay attention to the drying specifications. Primers must be dry when priming is applied to paints containing strong solvents, so as to avoid biting diseases.

4.增加下一道涂層與底漆間的附力,可在涂布前將底漆打磨。

4. increase the adhesion between the next coating and primer, so that the primer can be ground before coating.

5.要在漆前表面處理以后嚴格按照規定的時間及時涂布底漆。還要根據底漆品種規定的條件在底漆干燥后規定時間范圍內涂下一道漆。過早涂布可能引起咬底及底漆中溶劑揮發困難導致漆膜干燥時間延長、固化不良的情況;涂布過遲可能引起層間附著不良,且過遲涂布易由于粉塵積累或其他污染影響表觀。

5. before coating the surface, the primers should be coated in strict accordance with the prescribed time. A paint should also be applied within the specified time limit after the primer is dried according to the conditions stipulated in the primer. Early coating may cause priming and solvent evaporation difficulties in primers lead to prolonged drying time and poor solidification of the film; too late coating may lead to poor adhesion between layers, and too late coating may easily be affected by dust accumulation or other pollution.

底漆稀釋按照說明書和環氧樹脂地坪漆施工需要進行,控制好比例,嚴禁過量稀釋。

Primer dilution according to the instructions and epoxy resin floor paint construction needs, control the proportion, prohibit excessive dilution.

須在基面充分干燥、無異物的情況下進行,對地面必須進行清掃處理,對不符合要求的地面應及時向項目經理反映。

The ground must be cleaned when the base is fully dry and there is no foreign matter. If the ground does not meet the requirements, it should be reported to the project manager in time.

環氧樹脂地坪漆材料開桶后,應充分攪拌均勻再進行使用。

When the epoxy floor paint is opened, it should be fully stirred and used again.

先刷邊角及不易棍涂的部位,再由上往下進行大面積施工,不易吸料的環氧地坪用毛刷點刷環氧樹脂地坪漆底涂。

First brush the edges and corners and the parts which are not easy to stick, and then carry out large-scale construction from top to bottom, not easy to absorb material for the floor with brush point brush epoxy resin floor paint primer.

涂刷時,桶內必須設置滾板,棍筒和毛刷蘸料后必須在滾板上舔料后方可進行施工。

When painting, the barrel must be equipped with rollers, sticks and brushes dipped in the material must be on the rollers after licking material can be constructed.

若有毛刷毛或棍筒毛沾在墻上,應及時處理。

If brush hair or club hair is stained on the wall, it should be dealt with promptly.

由于溶劑揮發較快,若施工過程中底涂變稠影響施工,可適量添加溶劑,不過一般情況下,不建議采取這種辦法。

Due to the rapid volatilization of solvents, if the thickening of the primer during construction affects the construction, the appropriate amount of solvents can be added, but in general, this method is not recommended.

檢查地面是否有漏涂現象并加以修補。

Check if there is any leakage on the ground and repair it.

重涂時間一般大于6-8小時。

The repainting time is usually greater than 6-8 hours.

環氧地坪漆施工效果涂布率滿足要求;不允許有漏涂現象和流墜、明顯的接搓,做到棍涂均勻。若實際涂布率與該涂布率相差較大,應報請項目經理。

Epoxy floor paint construction effect coating rate to meet the requirements; do not allow the phenomenon of leakage coating and flow, obvious rubbing, to achieve uniform stick coating. If there is a big difference between the actual coating rate and the coating rate, it should be reported to the project manager.

環氧樹脂地坪漆施工的步驟中,底涂是至關重要的一點,只有將基面封閉好了,才能夠進行下一步涂裝,如果底涂沒有做好,就算后面的工藝做得再好,都將功虧一簣。

In the construction of epoxy floor paint, primer is a crucial point. Only when the base surface is sealed, can the next coating be carried out. If the primer is not done well, even if the later process is done well, it will be lost.

其他方面要注意的:

Other aspects should be noted:

膩子修補:

Putty Repair:

對水泥基層存在的凹坑,用商品環氧膩子或用底漆和細石英砂配置的環氧砂漿填平,在固化成膜后打磨平整。

For pits in cement base, fill them with commercial epoxy putty or epoxy mortar with primer and fine quartz sand, and then grind them smoothly after solidification.

中層涂料施工:

Middle level coating construction:

對于厚膜型涂料,中層涂料施工時可采用鏝刀鏝涂。由于涂料中使用的石英砂較多,一般情況下刮涂后涂膜不會出現明顯刮刀痕跡,但如果石英砂加入量過大,刮痕明顯時應輥壓一次。涂裝間隔如果大于48h,應進行打磨后再進行下道涂料的施工,以保證層間黏結力。

For thick film coatings, trowel trowel can be used in middle coating construction. Due to the use of more quartz sand in the paint, the film will not appear obvious scratch marks under normal circumstances, but if the addition of quartz sand is too large, scratch obvious should be rolled once. If the coating interval is greater than 48 hours, the next coating should be applied after grinding to ensure interlaminar adhesion.

面涂料施工:

Surface coating construction:

根據環氧耐磨地坪涂料的種類,面涂料可以采用刷涂或刮涂施工。對于厚膜型涂料,按配比要求將兩組份涂料混合均勻,待熟化后使用1mm刮板刮涂涂料。刮涂時應盡量保持厚膜均勻,無漏涂現象,無明顯余料。刮涂時,刮刀的移動速度應均勻,刮刀與地面平面夾角為30°左右,以保證涂膜厚度。刮涂道數根據厚度要求而定。普通環氧涂料則可以采取刷涂方法施工。面涂料施工時兩道之間的間隔時間應在18h以上,但不能大于48h。配置好的涂料應盡快用完,以防止涂料的黏度升高,涂料中的氣泡難于排出。

According to the types of epoxy abrasion resistant floor coatings, the surface coating can be constructed by brush or scraping. For thick film coatings, mix the two components evenly according to the proportion requirements, and use 1mm scraper coating after curing. During scraping, thick film should be kept as uniform as possible without any leakage. When scraping, the moving speed of the scraper should be uniform, and the angle between the scraper and the ground plane should be about 30 degrees to ensure the film thickness. The number of scraper passes depends on the thickness requirements. Ordinary epoxy coatings can be constructed by brush method. The interval between the two surfaces should be above 18h, but not more than 48h. The coatings should be used up as soon as possible to prevent the viscosity of the coatings from rising and the bubbles in the coatings are difficult to discharge.

環氧地坪養護:

Epoxy floor maintenance:

面涂料施工完,并完全固化后,一般應在面涂料施工24h以上方可上人,72小時后方可重壓。(25℃為準,低溫開放時間需適度延長。)

After the surface coating has been applied and completely cured, it should be applied for more than 24 hours before it can be applied, and 72 hours after it can be repressed. (at 25 C, the opening time at low temperature should be extended moderately).
