Embodiment 1

[0014] Mix 380kg of barium sulfate, 20kg of mica powder, 3kg of dispersant LX-7, 6kg of defoamer DP-602, and 1kg of AMP-5, and stir for 30 minutes to disperse until uniform without particles, then add 400kg of acrylic acid 5181 emulsion and stir for 15 minutes, and finally Add 4kg of thickener 8W and stir for 10 minutes to prepare a one-component waterproof coating.

[0015] According to the standard JC / T864-2008 to measure its performance, the elongation without treatment can reach 1200%, and the tensile strength can reach 1.5MPa; the elongation at break of acid treatment is 1200%, and the tensile strength is 1.2MPa; 1100%, the tensile strength is 1.5MPa.

Embodiment 2

[0017] Mix 500kg of barium sulfate, 30kg of mica powder, 4kg of dispersant LX-7, 6kg of defoamer DP-602, and 1kg of AMP-95, and stir for 30 minutes to disperse until uniform without particles, then add 400kg of acrylic acid 5181 emulsion and stir for 15 minutes, and finally Add 3.5kg of thickener 8W and stir for 10 minutes to prepare a one-component waterproof coating.

[0018] According to the standard JC / T864-2008 to measure its performance, the elongation without treatment can reach 850%, and the tensile strength can reach 1.98MPa; the elongation at break of acid treatment is 900%, and the tensile strength is 1.4MPa; 800%, the tensile strength is 1.8MPa.

Embodiment 3

[0020] Mix 420kg of barium sulfate, 30kg of mica powder, 3.5kg of dispersant LX-7, 6kg of defoamer DP-602, and 1kg of AMP-95, and stir for 30 minutes to disperse until uniform and particle-free, then add 400kg of acrylic acid 5181 emulsion and stir for 15 minutes. Finally, add 4kg of thickener 8W and stir for 10 minutes to prepare a one-component waterproof coating.

[0021] According to the standard JC / T864-2008 to measure its performance, the elongation without treatment can reach 1000%, and the tensile strength can reach 1.7MPa; the elongation at break of acid treatment is 1050%, and the tensile strength is 1.0MPa; 1100%, the tensile strength is 1.6MPa.

Abstract

The invention discloses a single-component waterproof coating and a preparation method thereof. The coating is prepared from the following raw materials by mass: 300 to 500 parts of an acrylic emulsion, 1 to 5 parts of a dispersing agent, 3 to 7 parts of a defoaming agent, 90 to 160 parts of water, 300 to 500 parts of barium sulfate, 20 to 50 parts of mica powder, 0 to 1 part of a functional regulator, 1 to 3 parts of cellulose and 3 to 5 parts of a thickening agent. The waterproof coating provided by the invention has the characteristics of convenient preparation and use, good chemical medium resistance and high extensibility, and has good economic benefits and market application prospects.

Description

technical field [0001] The invention belongs to the field of building waterproof materials, and relates to a chemical-medium-resistant and highly extensible one-component waterproof coating. Background technique [0002] With the enhancement of waterproof awareness, people pay more and more attention to the waterproof protection of buildings. Waterproof coatings are also widely used in building waterproofing projects, and people's requirements for waterproof coatings are becoming more and more stringent. The construction procedures of the waterproof coatings currently on the market are cumbersome, can only be used in neutral environments, and have relatively poor resistance to chemical media (acids, alkalis). The invention is easy to use, can be used after opening the barrel, has high elongation rate, and has excellent acid and alkali resistance. Contents of the invention [0003] The object of the present invention is to provide a one-component waterproof coating which i...
