Problems solved by technology

[0002] Wall coatings are popular because of their low toxicity, ease of use, and low price. However, currently commercially available wall coatings, such as latex paints (Nippon paints, etc.), have short service life, are not washable, and have poor weather resistance. , affected by the external climate, the coating is prone to aging, discoloration, wrinkling, peeling, etc. CN1385483A discloses a modified coating for interior and exterior walls of nanometers. It has good properties such as anti-aging, anti-aging, anti-ultraviolet, antibacterial, etc., but its resistance to cleaning and washing is only 11,000 times, and its artificial aging resistance is only 600 hours. In order to further improve the performance of wall coatings, it is necessary to improve the coatings. recipe

Abstract

The nano wall paint consists of filming material, stuffing, pigment, nano material and assistant and is prepared through conventional paint compounding process. Specifically, the material includes filming material 20-50 wt%, pigment and stuffing 15-45 wt%, assistant 1.0-5 wt%, nano material 0.2-2.0 wt%, water soluble micrographic carrier material 1.0-3.0 wt% and water 15-50 wt%. Owing to the water soluble micrographic carrier material and the nano material of particle size of 10-40 nm, the wall paint has high antifouling, antiageing and antibiotic performance, has water resistance over 20000-45000 times, artificial ageing resistance over 1000 hr and lowered nano material use amount and thus lowered production cost.
