Abstract

The invention discloses a durable building external wall paint which is prepared from the following raw materials in parts by weight: 10-15 parts of titanium white, 20-25 parts of white latex, 5.8-8.6 parts of sodium carboxymethyl cellulose, 8.7-9.6 parts of deionized water, 2.5-6.4 parts of cholesteryl acetate, 2.4-6.5 parts of 1,9-nonanediol, 2.4-6.2 parts of cinnamic aldehyde, 1.4-3.7 parts of diphenethyl phenol polyethenoxy ether, 3.5-7 parts of film former and 2.5-4.2 parts of white carbon black. Compared with the existing product, the durable building external wall paint has the advantages of favorable mildewproof and antibacterial effects, long service life, low production cost and soft smell. By using the white latex and sodium carboxymethyl cellulose as the base materials, the durable building external wall paint provides excellent adhesive force for various internal wall basal planes, lowers the water-absorbing capacity of the coated base layer, is beneficial to color uniformity of the finish paint, saves the consumption of the finish paint, enhances the glossiness, lowers the integral application cost, and enhances the wall surface painting effect.

Description

technical field [0001] The invention relates to a durable building exterior wall paint and a preparation method thereof, belonging to the field of building paints. Background technique [0002] The quality of house interior wall paint is directly related to people's health and quality of life. Inferior interior wall paint will mildew when used for a long time or under severe weather conditions for a long time, and bacteria will grow on the wall and produce The pungent smell has a strong impact on people's health, and its decorative effect and aesthetic effect are also greatly reduced, and repainting has increased people's economic burden. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a durable building exterior wall paint and a preparation method thereof, which have good anti-mildew and anti-bacterial effect, long service life and low production cost. [0004] In or...
