Problems solved by technology

However, adding fillers will easily lead to a great decrease in the transparency of the product. Since the grain of wood is one of the main features of wood, if you use wood paint with poor transparency, it will inevitably affect the display of wood grain and reduce the actual value of wood. Therefore, it is necessary to Improves the transparency of wood lacquers

Embodiment 1-3

[0023] A kind of high-transparency water-based wood lacquer, its raw material is made up of the following composition by weight:

[0024] The proportioning parameter of table 1 embodiment 1-3

[0025]

[0026]

[0027] The particle size of silicon dioxide is 15 μm.

[0028] The preparation method of coating is:

[0029] 1. Mix silicon dioxide and part of deionized water, stir at high speed, and stir at 800 rpm for 80 minutes to obtain a silicon dioxide pre-preparation;

[0030] 2. At a speed of 500 rpm, add water-based polyurethane emulsion, water-based epoxy resin, hexamethylolmelamine formaldehyde resin, methyl etherified amino resin containing high imino group, and ethylene glycol ether acetate in deionized water in sequence. ; At 600-1000 rpm, add silicon dioxide pre-preparation, quaternary ammonium salt, tetrafluoroethylene in turn, and then disperse at a high speed of 1200-1500 rpm for 10-60 minutes; at 100-400 rpm Add ethylene glycol monobutyl ether, silicone r...

Abstract

The invention discloses high-transparency waterborne wood lacquer, which is prepared from the following raw material ingredients in parts by weight: 50 to 75 parts of waterborne polyurethane emulsion,25 to 40 parts of waterborne epoxy resin, 20 to 35 parts of waterborne amino resin, 20 to 45 parts of silicon dioxide, 15 to 30 parts of quaternary ammonium salt, 2 to 5 parts of tetrafluoroethylene,5 to 10 parts of cosolvents, 4 to 8 parts of coalescing agents, 0.5 to 1 part of anti-foaming agents, 1 to 2 parts of thickening agents and 25 to 50 parts of deionized water. The wood lacquer has good toughness and ductility, and can be uniformly covered on wood; in addition, the transparency is high; the luster is given to the wood; meanwhile, the original veins of the wood can be seen.

Description

technical field [0001] The invention relates to a high-transparency water-based wood paint, which belongs to the technical field of functional paints. Background technique [0002] Water-based wood paint is favored by people because it does not contain organic solvents, is safe, environmentally friendly, and healthy. It has been successfully developed and put into the market in large quantities to meet people's decoration and decoration needs. There are roughly three types of water-based wood paint currently on the market: acrylic emulsion, polyurethane (PUD), and acrylic emulsion combined with PUD. However, due to the defects of low solid content, poor filling performance and low transparency in the common water-based wood lacquers on the market, there are certain difficulties in the promotion of such products. In order to improve the solid content and filling properties of water-based wood lacquers, researchers generally solve the problems of solid content and filling pro...
