Building decoration waterproof paint and preparation method thereof

Abstract

The invention discloses a building decoration waterproof paint and belongs to the technical field of building materials. The building decoration waterproof paint is composed of liquid materials and powder materials, wherein the liquid materials are composed of raw materials including, by weight part, 70-100 parts of acrylic emulsion, 0.5-1 part of flatting agent, 2-3 parts of dispersing agent, 0.05-0.1 part of wetting agent, 0.8-1 part of deformer and 1-2 parts of light stabilizer; the powder materials are composed of raw materials including, by weight part, 200-300 parts of cement, 80-150 parts of quartz powder, 50-60 parts of butyl rubber, 10-20 parts of petroleum asphalt, 90-120 parts of ground calcium carbonate, 5-10 parts of water reducer, 40-60 parts of waterproof powder, 10-20 parts of ultralight clay, 30-40 parts of diatomite, 5-10 parts of stearic acid and 8-12 parts of coal ash. The invention also discloses a preparation method of the building decoration waterproof paint. The building decoration waterproof paint is high in waterproof capacity and excellent in anti-cracking property.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a waterproof coating for building decoration and a preparation method thereof. Background technique [0002] Decoration engineering refers to the engineering of plastering, painting, brushing, glass, pasting, veneer, cover panel and floral decoration in the construction of houses. It is the last construction process of house construction, and its specific content includes interior and exterior walls. Plastering of surfaces and ceilings, interior and exterior wall finishes and veneers, floors and floors, installation of floral decorations on house facades, paint and paste of wooden and metal products such as doors and windows, etc. [0003] In decoration engineering, waterproof coatings are often used. There are two types of waterproof materials on the market: one is polyurethane waterproof coatings. Such materials are generally made of polyurethane and coal tar as raw...

AI Technical Summary

Problems solved by technology

[0004] However, with the uneven quality of real estate houses, cracks are prone to appear in kitchens, bathrooms, basements and other places, resulting in water seepage

Although the existing JS waterproof coatings on the market have a certain elongation rate, the surface of the coating film is prone to defects such as tiny cracks and pinholes, so that it cannot achieve the waterproof effect, and eventually leads to the failure of the waterproof project

[0005] In the public document of publication number CN104829207A, a polymer cement waterproof coating is disclosed. The coating includes a liquid material component and a powder material component. The liquid material component includes a polymer emulsion, triethanolamine, a dispersant, a preservative, a disinfectant Foaming agent, the balance is water; powder components include special cement, ultrafine slag, ultrafine steel slag, metakaolin, defoamer, water-soluble cellulose, powdered acrylamide, powdered bisacrylamide, instant silicic acid Sodium, aluminum stearate, the balance is 400 mesh heavy calcium carbonate, the invention has excellent anti-sagging and anti-cracking properties, and has self-repairing function, can form crystals inside the concrete, and has certain secondary impermeability function, but the ability to resist cracking is still insufficient and can still be further strengthened
