Problems solved by technology

[0002] General metope all will scrape a layer of putty paste to make a primer after plastering, and then coat coatings such as latex paint, putty paste is widely used as an indispensable decorative material in wall coatings, but existing putty paste is attached The force is not strong enough, especially for smooth surfaces such as mosaics and tiles, the mosaics, tiles and other surfaces must be knocked off before applying the putty paste, but you can also use 107 glue mixed with cement to re-powder or white latex mixed with white cement to re-powder. Powder primer, however this will make the effect of the paint less than ideal
In addition, the existing putty paste is prone to cracks after thermal expansion and contraction, and the coating covering the surface also cracks correspondingly, affecting the appearance of the wall
Moreover, the existing putty pastes have poor alkali resistance. If the alkali in the wall is too strong and pan-alkaline, it is generally necessary to apply a layer of anti-alkali primer on the wall, and then scrape the putty, otherwise the outer layer of paint will turn yellow , Paint film bubbling, peeling, coating powdering and other phenomena after drying
Some putty pastes also contain toxic raw materials, which affect human health

Embodiment Construction

[0018] The present invention will be further described below with embodiment:

[0019] Formula 1: according to weight ratio (%) Shuangfei powder 30-35, light calcium carbonate 15-20, thickener 1.5-2.0, acrylic emulsion 30-35, anti-fungal agent 1.5-2.0, plasticizer 2.5-3.0, The ratio of defoamer 1-2, antifreeze agent 6-8, and film-forming aid 4-6, first put a certain amount of acrylic emulsion into the mixer, start stirring, and then put double fly powder, light calcium carbonate, Thickener, antifungal agent, plasticizer, defoamer, antifreeze and film-forming aids, continue to stir until a uniform paste is formed, which is suitable for batch scraping, and the environmentally friendly elastic wall putty paste is obtained, and finally shut down and discharge , after testing all performances to be qualified, it is packaged and put into storage according to the standard capacity.

[0020] Formula 2: According to weight ratio (%) gypsum powder 30-35, talc powder 15-20, heavy calciu...

Abstract

The environment-protecting elastic wall putty is prepared by mixing densifier, polyacrylate emulsion, anti-mildew agent, plasitcizer, defoaming agent, antifreezing, agent, and filming agent and two -component calcium carbonate powder and light calcium carbonate, or gypsum powder, talcum powder and heavy calcium carbonate powder. The environment-protecting elastic wall putty is used in base coating with strong adhesion, high elasticity, high alkali resistance, safety no toxicity and no crack, no stripping, no yellowing, no mildew and no powdering.

Description

technical field [0001] The invention relates to an architectural coating, in particular to an architectural coating with strong adhesion, elasticity, alkali resistance, environmental protection and non-toxicity and a preparation method thereof. Background technique [0002] General metope all will scrape a layer of putty paste to make a primer after plastering, and then coat coatings such as latex paint, putty paste is widely used as an indispensable decorative material in wall coatings, but existing putty paste is attached The force is not strong enough, especially for smooth surfaces such as mosaics and tiles, the mosaics, tiles and other surfaces must be knocked off before applying the putty paste, but you can also use 107 glue mixed with cement to re-powder or white latex mixed with white cement. Powder primer, however this will make the effect of the paint less than ideal. In addition, the existing putty paste is prone to cracks after thermal expansion and contraction,...
