Problems solved by technology

[0004] But the light reflection ability and heat insulation ability of the waterproof coating film that this waterproof coating forms after curing are poor, and the sunlight irradiates on the metal roof that is coated with this coating, can make the temperature in building room rise rapidly, and indoor ventilation effect Poor, resulting in poor heat dissipation, which increases the use of other cooling methods such as air conditioners, which not only increases the consumption of power resources, but also is not conducive to people's health when using air conditioners for a long time

preparation example 1

[0034] The thermal insulation filler titanium dioxide / ethyl cellulose composite porous microsphere material is prepared by the following method:

[0035] S1, adding ethyl cellulose to hexyl acetate, stirring evenly, then adding nano-titanium dioxide particles (selected from rutile nano-titanium dioxide particles) and stirring evenly; S2, adding sodium lauryl sulfate to ethyl acetate saturated in the aqueous solution and stirred evenly; S3, the solution obtained from S1 was added to the solution obtained from S2 and stirred uniformly; S4, the solution obtained from S3 was added to the deionized aqueous solution of sodium lauryl sulfate and stirred uniformly; S5, The solution obtained in S4 was vacuum filtered to collect the powder and dried; wherein the weight ratio of nano-titanium dioxide particles to ethyl cellulose was 1:2.

preparation example 2

[0037] The difference from Preparation Example 1 is that the weight ratio of nano-titanium dioxide particles to ethyl cellulose is 1:3.

preparation example 3

[0039] The difference from Preparation Example 1 is that the weight ratio of nano-titanium dioxide particles to ethyl cellulose is 1:4.

Abstract

The invention relates to the technical field of building waterproof coatings, and particularly discloses a metal roof acrylic acid high-elastic waterproof coating and a preparation method thereof. The coating is prepared from the following components in parts by weight: 55 to 75 parts of pure acrylic acid emulsion, 5 to 15 parts of titanium dioxide, 15 to 25 parts of talcum powder, 15 to 25 parts of ground calcium carbonate, 1 to 2 parts of a dispersing agent, 0.5 to 1 part of a defoaming agent, 0.2 to 0.4 part of a bactericidal mildew preventive, 1.5 to 3 parts of a coalescing agent, 0.5 to 0.8 part of a thickening agent, 10 to 20 parts of deionized water, 0.6 to 1 part of ethylene glycol and 7 to 12 parts of heat insulation filler; wherein the heat insulation filler is a titanium dioxide / ethyl cellulose composite porous microsphere material. The acrylic acid high-elastic waterproof coating for the metal roof has better light reflection capacity and heat insulation capacity and has better water resistance, adhesiveness, extensibility and elastoplasticity.

Description

technical field [0001] The application relates to the technical field of architectural waterproof coatings, more specifically, it relates to a metal roof acrylic high-elastic waterproof coating and a preparation method thereof. Background technique [0002] In the construction and decoration process of the house, some places need to be waterproofed, and applying waterproof coating is a common method. Architectural waterproof coating is a viscous liquid polymer synthetic material with no fixed shape at room temperature. After coating, it can form a tough waterproof coating film on the surface of the base layer after the volatilization of solvent or water evaporation or reaction curing. the general term for. [0003] At present, high-elastic acrylic waterproof coating is a relatively commonly used waterproof coating. It is a one-component water-emulsion waterproof coating prepared by adding acrylate polymer emulsion as a base material and adding other additives; this waterpro...
