Modified nano-titanium dioxide with tenacity and good damp-proof effect, and preparation method of modified nano-titanium dioxide

Abstract

The invention discloses modified nano-titanium dioxide with tenacity and a good damp-proof effect. The modified nano-titanium dioxide is characterized by being prepared from the following raw materials in parts by weight: 85-90 parts of nano-titanium dioxide, 1.5-3 parts of sodium silicate, 2-3 parts of attapulgite clay, 5-6 parts of polyamide resin, 1-2 parts of sorbitol, 1.5-2 parts of monobutyltin oxide 80, 5.5-6.6 parts of dimethylaminoethyl acrylate, 4-5 parts of titanium carbide whiskers, 1-1.5 parts of triethanolamine, and 2-3 parts of modified silicon dioxide. The modified nano-titanium dioxide is reasonable in formula; through the added attapulgite clay, the modified nano-titanium dioxide has an excellent damp-proof effect, and the hydrophilicity of the nano-titanium dioxide can be reduced; through the added high-molecular polymer, the compatibility of the modified nano-titanium dioxide and an organic matter can be increased, the self mechanical performance of the modified nano-titanium dioxide can be increased, the tenacity is enhanced, a preparation method is simple, the prepared coating is uniform in a coated film, and not easy to crack, and the modified nano-titanium dioxide is simple and easily available in raw materials, and convenient to popularize and use.

Description

technical field [0001] The invention relates to the field of industrial fillers, in particular to a modified nano-titanium dioxide with good toughness and moisture-proof effect and a preparation method thereof. Background technique [0002] Due to its good UV resistance, good weather resistance, chemical resistance, heat resistance, photocatalysis, thermal stability, and harmless to human body, nano titanium dioxide is widely used in pigments such as paint, rubber, plastic , papermaking and other industries, and is also widely used as photocatalyst, photoelectric cell, ultraviolet shielding agent, etc. Titanium dioxide nanoparticles contain hydroxyl groups on the surface, which can easily absorb moisture in the air and exhibit hydrophilic properties, so they are not easy to disperse in the organic phase, resulting in serious phase separation between titanium dioxide particles and organic matter. Therefore, when preparing titanium dioxide / polymer nanocomposites, the surface ...
