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

[0017] The preparation method of epoxy waterproof coating is:

[0018] (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.

[0019] (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

[0021] The preparation method of epoxy waterproof coating is:

[0022] (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.

[0023] (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

[0025] The preparation method of epoxy waterproof coating is:

[0026] (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.

[0027] (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 a preparation method of epoxy waterproof coating. The preparation method comprises the following steps: (1) respectively weighing the following components in percentage by weight: 15%-23% of deionized water, 30%-40% of bisphenol A epoxy resin, 8%-15% of fluorocarbon emulsion, 5%-10% of organosilicon, 5%-10% of nanometer hollow glass fiber, 10%-18% of nitrile-butadiene rubber, 0.5%-0.9% of dispersing agent, 0.4%-0.8% of defoaming agent, 0.4%-0.8% of preservatives, dispersing and stirring to obtain a mixture; and (2) weighing and adding the following raw materials in percentage by weight: 10%-17% of flake highly wear-resistant pigment fillers and 0.2%-0.5% of leveling agent into the mixture, and dispersing and stirring for 10-15 minutes in the dispersion tank with the rotating speed of being 1000-1500r / min. By adopting the preparation method, the epoxy waterproof coating with good impact resistance and good waterproof property can be prepared, and the process is simple.

Description

technical field [0001] The invention relates to a preparation method of 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 a kind of preparation method of epoxy waterproof coating, utilize the preparation method of the present invention, can prepare a ...
