Abstract

Multifunctional dustproof self-cleaning wall paint relates to wall paint and solves the problems of high cost, complex preparation method and no sterilizing and self-cleaning functions in traditional dustproof wall paint. The multifunctional dustproof self-cleaning wall paint is prepared from deionized water, inorganic pigment filler, resin emulsion, a hydrophobic additive with low surface tension, a functional nano material, a thickening agent, a pH regulator, a defoaming agent, a dispersing agent, a film coalescing aid and an antifreezing agent. The multifunctional dustproof wall paint disclosed by the invention is simple and convenient in preparation method, low in cost and suitable for various substrates, can be directly used for coating outer walls of various buildings on large scale and has excellent self-cleaning property for outer walls attached to the buildings and the outsides of various building facilities. In addition, the multifunctional dustproof wall paint has excellent outdoor ageing resistance and has a contact angle for water of more than or equal to 120DEG C, artificial acceleration ageing resistant time of more than or equal to 1000 hours, the decomposition capacity for oil stain of over 98 percent and killing performance for mould and Eschera coli of over 99 percent.

Description

technical field [0001] The present invention relates to wall paint. Background technique [0002] With the continuous and stable growth of my country's economy and the continuous improvement of people's living standards, the construction and decoration industry is developing rapidly, and the annual demand for interior and exterior wall coatings in China can reach more than several million tons. However, the typical disadvantages of interior and exterior wall architectural coatings at home and abroad are poor stain resistance and poor outdoor durability, which makes the exterior walls of buildings, especially buildings and other construction facilities near various roads (highways, railways, urban roads) There is often all kinds of dust. Dirt, oil stains, etc., greatly affect the appearance. [0003] Although the outdoor durability, water resistance and stain resistance of the silicon-acrylic exterior wall latex paint and fluorocarbon paint produced in the later development...
