2. Curing agent: Solvent-free high-performance epoxy curing agent produced by HUNSMAN and AIR PRODUCTS;

3. Additives: Select series of defoamers, leveling agents, wetting and dispersing agents and surface improvers produced by BYK and DEGO.

4. Pigments: Select titanium dioxide produced by DUPONT and a series of pigments produced by DEGUSSA.

two. 2.0mm flat coating epoxy floor construction design

1. Features: It is dust-free, seamless, smooth and smooth after overall molding. It has excellent mechanical strength, good chemical resistance and water resistance, easy to clean and a variety of color appearance.

2. Construction process:

1) Base requirements:

The base surface should be flat and free of oil. The strength of the concrete should not be lower than C20. The new concrete must reach the curing period. The concrete on the first floor must be constructed with a waterproof layer and effective. The moisture content of the base surface is less than 6%.

2) Base treatment and primer application:

a. Remove all debris from the original floor plane;

b. For the actual situation of the base surface, use special base surface grinding equipment to thoroughly polish the base surface and maximize the base surface to increase the adhesion of the primer and the base surface. After the polishing, use a large-scale The industrial vacuum cleaner thoroughly cleans the base surface. If the base surface is oily, it must be completely removed. The cavity crack must be repaired with epoxy resin mortar.

c. Before the primer is applied, the base surface must be dry, dust-free, crack-free, no cement floating, no pitting, no porosity;

d. Apply the special epoxy sealing primer (EC-30#) of Shanghai Jiannai Company, the standard dosage: ~ 0.15kg/m2.

3) Construction of the first epoxy mortar layer:

After the primer is cured, the first epoxy lacquer layer is applied, Shanghai Jiannai Epoxy Intermediate Paint (EF-600), dosage: 1.0kg/m2, and 7# quartz sand 1.0kg/m2. After the epoxy mortar layer is cured, it is slightly polished.

4) Construction of the second epoxy mortar layer and putty layer:

After the first epoxy mortar layer is cured, the second epoxy mortar is applied to the paint layer. Guangzhou Mingfeng Epoxy Intermediate Paint (EP-204), dosage: 1.0kg/m2, with 8# quartz sand 0.5kg /m2. After curing, sand and vacuum. Construction of epoxy putty layer, Shanghai Jiannai epoxy paint (EF-600), dosage: 0.15kg/m2, with quartz powder 0.1kg/m2.

5) Topcoat construction:

Check the epoxy putty layer with or without residual pores, with or without protruding powder, and fill the pores and sanding in time, and finally apply a flat topcoat together. Shanghai is resistant to solvent-free high solids containing pure epoxy flat topcoat. (Model: EC-148), the dosage is 0.15kg/m2, which achieves a smooth and smooth surface effect.
