Problems solved by technology

However, the functions of water-based paints in the existing market are relatively single, which can only solve the volatilization hazards caused by traditional solvent-based paints, but other comprehensive properties have declined compared with traditional solvent-based paints. Therefore, there is an urgent need for an environmentally friendly, comprehensive performance. furniture painting

Embodiment 1

[0021] A furniture paint, calculated in parts by weight, comprising the following components:

[0022] 45 parts of water-based polyurethane resin, 20 parts of acrylate emulsion, 6 parts of water-based epoxy resin, 12 parts of magnesium aluminum hydrotalcite, 4 parts of modified titanium dioxide, 6 parts of dispersant and 50 parts of water.

[0023] The preparation method of modified titanium dioxide comprises the following steps:

[0024] (1) Put titanium dioxide into an aqueous solution containing a mass concentration of 12% cetyltrimethylammonium bromide, stir and ultrasonically disperse to obtain dispersion A;

[0025] (2) Silicon carbide is added into the silica sol for ultrasonic dispersion to obtain dispersion B;

[0026] (3) After mixing the dispersion liquid A and the dispersion liquid B, they are fully mixed and ground, and then sintered by hot pressing at 300°C to obtain the modified titanium dioxide. The mass ratio of titanium dioxide to silicon carbide is 8:1, an...

Abstract

The invention provides furniture paint which is prepared from the following components in parts by weight: 40-50 parts of waterborne polyurethane resin, 15-25 parts of acrylate emulsion, 4-8 parts ofwaterborne epoxy resin, 8-16 parts of magnesium-aluminum hydrotalcite, 3-6 parts of modified titanium dioxide, 4-10 parts of additive and 40-60 parts of water. The modified titanium dioxide is mainlyprepared by performing hot pressed sintering on titanium dioxide, silicon carbide and silica sol. The furniture paint is good in adhesion force and film formation performance and also has excellent formaldehyde removal performance.

Description

technical field [0001] The invention belongs to the technical field of paint, and in particular relates to a paint for furniture. Background technique [0002] With the improvement of the quality of human life, environmental protection regulations are becoming more and more stringent. Various environmental protection regulations have strict restrictions on the emission of volatile organic compounds (VOC), harmful solvents and various heavy metals. In the 1990s, actions to reduce solvent content and VOC in coatings were launched worldwide, which had a great impact on the industrial coatings and specialty coatings industries. Therefore, the development of green and environment-friendly coatings has become the development trend of the coatings industry. [0003] Nowadays, people have higher and higher requirements for the quality of life, pursuit of a perfect life, etc., and they also have higher requirements for wooden furniture in life. At present, most of the paint materia...
