Embodiment 1

[0015] 1. The environmental-friendly water-based nanometer anti-aging exterior wall paint of the present invention, the preparation of described environmental protection additive: 15 mass parts of tourmaline powder, 2 mass parts of antimicrobial micropowder and 83 mass parts of water are mixed uniformly to obtain finished product.

[0016] 2. the environment-friendly water-based nano anti-aging exterior wall paint of the present invention, the preparation of described water-based nano anti-aging agent: with nano material 28%, S 3 Add 6% of surface treatment agent, 1.5% of 2-amino 2-methyl-1-propanol, 6% of propylene glycol, 0.17% of fungicide and 58.33% of water into the mixer and mix thoroughly to obtain the finished product. The solid content of the obtained finished product is 30.5%, the average particle size is 12.3nm, the pH=9.7, and the viscosity is 32×10 -3 Pa·s, it has a strong absorption in the ultraviolet band (200-400nm).

Abstract

The invention relates to an environment-friendly water-based nano anti-aging exterior wall coating which comprises the components by weight percent: 15-30% of polyacrylic acid emulsion, 1-5% of film-forming additive, 0.1-0.3% of defoaming agent, 0.5-1% of dispersing agent, 0.1-0.5% of wetting agent, 2-5% of flatting agent, 1-6% of emulsifying agent, 15-25% of titanium dioxide, 2-5% of precipitated calcium carbonate, 0.5-3.5% of mica, 1-3% of zinc oxide, 3-7% of sodium silicoaluminate, 1.5-4.5% of talcum powder, 0.5-1% of thickening agent, 0.3-0.5% of mildew preventive, 10-30% of water, 2-5% of environment-friendly additive and 1-3% of water-based nano anti-aging agent. The environment-friendly water-based nano anti-aging exterior wall coating is good in scuff resistance, high in sandstorm impact resistance and even in coating without crack, can be used for blade coating, roller coating and spraying, has the functions of inhibiting bacteria, dispelling peculiar smell and cleaning air, and is remarkable in anti-man-made aging performance.

Description

technical field [0001] The invention relates to an exterior wall paint, in particular to an environment-friendly water-based nano anti-aging exterior wall paint. Background technique [0002] Architectural coatings are something that people are exposed to all the time in their daily lives, but many architectural coatings can volatilize toxic gases, which endanger people's health, including respiratory tract infections, digestive tract infections, and nervous system diseases. With the continuous development of science and technology, people's requirements for building materials are also constantly increasing. They must be safe, environmentally friendly and durable. The coatings on the market can no longer meet various needs. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art, and to provide an environment-friendly water-based nanometer anti-aging exterior wall coating, which can be used fo...
