A modified nano-titanium dioxide with good dispersion and good anti-ultraviolet effect and its preparation method

Abstract

The invention discloses modified nano-titanium dioxide with good dispersity and good uvioresistant 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, 3-4 parts of far infrared ceramic powder, 2-3 parts of talcum powder, 3-5 parts of crushed wood fibers, 1-2 parts of aluminum sulfate, 1-2 parts of caprylic / capric triglyceride, 3.5-5 parts of bone glue, 1-1.5 parts of sodium hexametaphosphate, 0.8-1.2 parts of dispersing agents NNO, 4-6 parts of acrylic acid-2-propylparaben and 2-3 parts of modified silicon dioxide. According to the modified nano-titanium dioxide disclosed by the invention, the ultraviolet shading effect of nano-titanium dioxide is enhanced because powder, such as the far infrared ceramic powder and the caprylic / capric triglyceride which have ultraviolet shading effects, is added and matched with nano-titanium dioxide; the dispersive effect is enhanced because the crushed wood fibers, the sodium hexametaphosphate and the dispersing agents NNO are added; by being added to a coating, the modified nano-titanium dioxide disclosed by the invention has the advantages of good film coating effect and good dispersive effect; a coated film has the advantages of ageing resistance and ultraviolet resistance.

Description

technical field

[0001] The invention relates to the field of industrial fillers, in particular to a modified nano-titanium dioxide with good dispersion and good anti-ultraviolet 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.; the surface of nano-titanium dioxide without surface treatment is generally covered by polar groups (such as -OH), so nano-titanium dioxide is easy to be damaged by Polar adsorption or moisture absorption leads to agglomeration, which becomes a larger aggregate with several weakly connected interfaces, and is difficult to disperse in organic solvents, so that its indust...
