Multiple-effect high-molecular water paint

Abstract

The invention relates to a multiple-effect high-molecular water paint which comprises the following components in percentage by weight: 51-59% of ethylene-acetate polymer, 27-36% of pigment filler, 2.1-8.5% of additive and balance of deionized water. The pigment filler comprises 9-12% of titanium pigment, 5-6% of calcium carbonate, 4-7% of kaolin and 9-11% of silica powder. The additive comprises 0.2-0.5% of block polymer, 0.3-2% of acid gene copolymer solution, 0.1-1.5% of alkoxy non-ionic compound, 0.1-0.3% of modified polyorganosiloxane, 0.2-1.3% of alkyl benzotriazole, 0.2-0.4% of aqueous adherence promotor, 0.5-1.5% of dodecyl acetate and 0.5-1% of bactericide. The invention has the functions of superelasticity, waterproofing, rust protection, thermal insulation, noise reduction, multiple colors and the like, and has the advantages of favorable properties, wide applicability, no environmental pollution and no harm to human bodies; and the technical indexes of the paint exceed the Chinese standard.

Description

technical field [0001] The invention relates to a polymer water-based paint with superelasticity, waterproof and antirust multi-effects. Background technique [0002] Waterproof materials used in the construction industry are generally divided into three categories: coiled materials, solvents, and asphalt ointment. However, there are problems such as high-temperature flow, low-temperature embrittlement, low tensile strength, low elongation, and poor adhesion. At the same time, the colors of the three materials are all black, so these products have strong heat absorption, easy cracking, aging and pollute the environment, etc. Moreover, the effect of seamless waterproofing cannot be achieved at all, and the worldwide problem of building waterproofing cannot be solved. [0003] Most of the exterior walls of existing concrete buildings in my country still use exterior wall bricks. The weight of exterior wall bricks is generally more than 8 kilograms per square meter, because t...

Problems solved by technology

However, there are problems such as high-temperature flow, low-temperature embrittlement, low tensile strength, low elongation, and poor adhesion. At the same time, the colors of the three materials are all black, so these products have strong heat absorption, easy cracking, aging and pollute the environment, etc.

Moreover, the effect of seamless waterproofing cannot be achieved at all, and the worldwide problem of building waterproofing cannot be solved.

[0003] Most of the exterior walls of existing concrete buildings in my country still use exterior wall bricks. The weight of exterior wall bricks is generally more than 8 kg per square meter, because the increase in wall weight greatly affects the service life of buildings.

Moreover, the wall tiles are not waterproof, prone to falling off and potential safety hazards

At the same time, the extensive use of wall bricks consumes a lot of non-renewable resources such as soil and coal.

[0004] In addition, solvent-based paints (paints) have only a single effect and do not have multi-effect functions. Regulators (thinner, etc.) must be added during use. Moreover, the content of formaldehyde and organic compounds (VOC) is high, and the aging time is short. , causing great environmental pollution

At the same time, the coating is hard, and the thickness can only be 0.02mm-0.03mm
