Abstract

The present invention provides one new kind of uvioresistant material. The host material of X, Y, A, STI, ZSM-5, MCM-41 series, SBA-15 series or other microporous and mesoporous molecular sieve and the guest material of nanometer cluster compound TiO2, ZnO, CeO2 or Fe2O3 are synthesized into the nanometer composite host-guest material. The synthetic material exhibits powerful absorption in UVA-UVB bands and thus may be used as ultraresistant agent for cosmetics, paints, rubber and plastic industry.

Description

technical field [0001] The invention relates to the synthesis of anti-ultraviolet materials, in particular to a crystalline pore material such as zeolite molecular sieve and mesoporous molecular sieve as the main body, and nano-cluster TiO 2 , ZnO, CeO 2 , Fe 2 o 3 Anti-ultraviolet material as a guest, its preparation method and application. Background technique [0002] Due to the development of modern industry, air pollution has intensified in recent years, and the destruction of the ozone layer has become increasingly serious. Anti-ultraviolet radiation has become an urgent problem in quite a few fields. The harm of excessive ultraviolet rays is mainly reflected in the following aspects: [0003] 1: When ultraviolet rays irradiate organisms, they will damage the peptide chains that make up proteins, resulting in the generation of free radicals. Free radicals will further interact with other peptide chains and eventually lead to tissue damage and gene mutation. For ...
