Problems solved by technology

[0003] So far, in order to solve the above problems, many thermal insulation coatings using different raw materials have appeared, such as a thermal insulation coating disclosed in Chinese patent 200910061883.6, which can play a good waterproof and thermal insulation effect, but , the amount of titanium dioxide and diatomaceous earth filler used in the formula is relatively high, which increases the production cost of the coating, and there are deficiencies in compactness, adhesion and anti-yellowing performance

preparation example Construction

[0026] The preparation method of the anti-seepage and heat-insulating coating of the present invention is prepared through the following steps:

[0027] (1) Add deionized water into the reaction tank with disperser and start the disperser;

[0028] (2) While stirring, add dispersants, wetting agents, defoamers, preservatives, antifungal agents, functional additives, antifreeze, and film-forming additives into the reaction tank in sequence, and stir to form a uniform Dispersions;

[0029] (3) Then increase the stirring speed, heat the reaction tank to 40-60°C, then add rutile titanium dioxide, talc powder, and hollow microsphere powder in sequence, and stir to disperse evenly;

[0030] (4) Finally, add silicon-acrylic emulsion and alkali-swellable thickener in sequence, stir for 10-20 minutes, and it is ready.

[0031] The dispersant mentioned in the following examples of the present invention is the SN-5040 dispersant produced by San Nopco Corporation of Japan; the wetting a...

Abstract

The invention relates to the field of an outer wall coating industry, and in particular relates to a seepage-proofing thermal-insulating coating and preparing method thereof. The seepage-proofing thermal-insulating coating is a composition which is prepared from the following ingredients in parts by weight: 25-25 parts of deionized water, 0.1-1 part of dispersing agent, 0.1-0.5 part of wetting agent, 0.1-0.5 part of antifoaming agent, 0.1-0.5 part of preservative, 0.1-1 part of mildew preventive, 0.1-0.5 parts of multifunctional assistant, 1-5 parts of anti-freezing agent, 1-5 parts of film forming assistant, 5-10 parts of rutile titanium dioxide, 3-8 parts of talcum powder, 5-10 parts of hollow microsphere powder, 30-40 parts of silicone acrylic emulsion and 1-5 parts of alkali swelling type thickening agent. With the seepage-proofing thermal-insulating coating provided by the invention, the production cost of the coating is further reduced; the coating is good in compactness, so that the coating has better seepage-proofing and waterproof functions; and in addition the coating has excellent performances such as adhesive force and yellowing resisting function.

Description

technical field [0001] The invention relates to the field of exterior wall coating industry, in particular to an anti-seepage and heat-insulating coating and a preparation method thereof. Background technique [0002] With the continuous development of the construction field, the absorption range of concrete to the spectrum is large, the heat storage is large, and the wall surface heats up quickly and lasts for a long time; especially in the south, the temperature in summer is above 30°C for a long time, which leads to The room heats up. Therefore, in order to reduce the indoor temperature and improve the comfort of the human body, people have to use fans, air conditioners and other equipment to reduce the indoor temperature, which consumes a lot of electric energy. out of place. How to solve the heat insulation problem of the building wall is particularly important. [0003] So far, in order to solve the above problems, many thermal insulation coatings using different ra...
