Abstract

The invention relates to a composite modified nanometer anti-ultraviolet exterior wall panel which is characterized in that raw materials of the exterior wall panel contain the following ingredients, by weight, 35-40 parts of cement, 3-3.5 parts of sodium silicate, 25-40 parts of expanded perlite, 5-8 parts of nano-zinc oxide. The composite modified nanometer anti-ultraviolet exterior wall panel is low-cost, has less pollution, is less harmful to human body, has good scuff resistance and strong ageing resistance, and is suitable for exterior decoration of buildings.

Description

technical field [0001] The invention relates to a material, in particular to a composite modified nanometer anti-ultraviolet wallboard. Background technique [0002] With the continuous progress of society, people have higher requirements for building materials. In addition to coating effects, people pay more attention to environmental protection and high performance. However, in the field of general environment-friendly buildings, problems such as easy cracking, leakage and hydrolysis pulverization of the outer wall surface of buildings are common, and these problems are also a major quality problem of today's building materials. Moreover, currently commercially available environmentally friendly building materials usually have short lifespan, poor weather resistance and other shortcomings. Therefore, in order to make up for the shortcomings of traditional environmental protection building materials and improve the performance of exterior wall materials, it is necessary to...
