Problems solved by technology

[0003] Traditionally, the coatings are made of organic solvents, which are highly polluting. Therefore, water-based coatings have been widely used now. For exterior wall coatings, one of the important technical problems that need to be solved is heat insulation and waterproofing. However, the existing water-based coatings have poor thermal insulation and waterproof performance.

Embodiment 1

[0026] The preparation method of epoxy waterproof coating is:

[0027] (1) By weight, weigh 150g of deionized water, 300g of bisphenol A epoxy resin, 150g of fluorocarbon emulsion, 100g of silicone, 85g of nano-hollow glass fiber, 100g of NBR, 5g of dispersant, and 4g of defoaming agent agent, 4g preservative, and add them into the dispersion tank together, disperse and stir at the speed of 300-500r / min in the dispersion tank for 5-10 minutes to obtain the mixture.

[0028] (2) Weigh 100g of flaky high wear-resistant pigments and fillers and 2g of leveling agent into the mixture, disperse and stir at the speed of 1000-1500r / min in the dispersion tank for 10-15 minutes to obtain epoxy waterproof coating. The flaky high wear-resistant pigments and fillers consist of 320 mesh glass flakes with a content of 2g, 160 mesh glass flakes with a content of 3g and sericite powder with a content of 5g.

Embodiment 2

[0030] The preparation method of epoxy waterproof coating is:

[0031] (1) By weight, weigh 160g of deionized water, 400g of bisphenol A epoxy resin, 80g of fluorocarbon emulsion, 50g of silicone, 50g of nano-hollow glass fiber, 120g of NBR, 9g of dispersant, and 8g of defoaming agent agent, 8g preservative, and add them into the dispersion tank together, disperse and stir at the speed of 300-500r / min in the dispersion tank for 5-10 minutes to obtain the mixture.

[0032] (2) Weigh 110g of flaky high wear-resistant pigments and fillers and 5g of leveling agent into the mixture, disperse and stir at the speed of 1000-1500r / min in the dispersion tank for 10-15 minutes to obtain epoxy waterproof coating. The flaky high wear-resistant pigments and fillers consist of 320 mesh glass flakes with a content of 2g, 160 mesh glass flakes with a content of 3g and sericite powder with a content of 6g.

Embodiment 3

[0034] The preparation method of epoxy waterproof coating is:

[0035] (1) By weight, weigh 150g deionized water, 300g bisphenol A epoxy resin, 80g fluorocarbon emulsion, 50g silicone, 100g nano-hollow glass fiber, 120g NBR, 9g dispersant, 8g defoamer agent, 8g preservative, and add them into the dispersion tank together, disperse and stir at the speed of 300-500r / min in the dispersion tank for 5-10 minutes to obtain the mixture.

[0036] (2) Weigh 170g of flaky high wear-resistant pigments and fillers and 5g of leveling agent into the mixture, disperse and stir at the speed of 1000-1500r / min in the dispersion tank for 10-15 minutes to obtain epoxy waterproof coating. The flaky high wear-resistant pigments and fillers consist of 320 mesh glass flakes with a content of 4g, 160 mesh glass flakes with a content of 6g, and sericite powder with a content of 7g.

Abstract

The invention discloses epoxy waterproof paint. The epoxy waterproof paint is prepared from the following raw materials in percentage by weight: 30%-40% of bisphenol A epoxy resin, 8%-15% of fluorocarbon emulsion, 5%-10% of organic silicon, 5%-10% of nano hollow glass fibers, 10%-18% of nitrile rubber, 10%-17% of sheet-shaped highly wear-resistant pigment filler, 0.5%-0.9% of a dispersant, 0.4%-0.8% of a defoaming agent, 0.4%-0.8% of a preservative, 0.2%-0.5% of a leveling agent and 15%-23% of deionized water. The epoxy waterproof paint disclosed by the invention is good in impact resistance and good in water resistance.

Description

technical field [0001] The present invention relates to epoxy waterproof paint. Background technique [0002] In various fields, coatings are widely used, such as exterior walls, industrial warehouses, chemical, petroleum, food industry storage tanks and pipeline surfaces, factories, modern farms, freezers, private houses, office buildings and other buildings, etc. . [0003] Traditionally, the coatings are made of organic solvents, which are highly polluting. Therefore, water-based coatings have been widely used now. For exterior wall coatings, one of the important technical problems that need to be solved is heat insulation and waterproofing. But its thermal insulation and waterproof performance of existing water-based coatings are all poor. Contents of the invention [0004] The purpose of the present invention is to provide an epoxy waterproof coating with good impact resistance and good waterproof performance. [0005] In order to achieve the above object, an epoxy...
