Example Embodiment

[0016] Example one

[0017] The first embodiment provides a two-component polyurethane coating, which is composed of component A and component B. The component A is calculated in parts by weight and includes the following components: 5 parts of acrylic resin dispersion, ethylene glycol ethyl ether acetic acid 4 parts of ester, 5 parts of resin containing active hydrogen, 12 parts of fillers, 8 parts of chitin derivative formaldehyde removal auxiliary, 1 part of anti-settling agent, 1 part of defoaming agent, 2 parts of drier; component B is by weight In parts, it includes the following components: 7 parts of isocyanate and 10 parts of toluene diisocyanate trimer.

[0018] In this embodiment, the active hydrogen-containing resin is an amino alkyd polyol. Of course, this choice is not a limitation. Other active hydrogen-containing resins can also be selected, as long as the active hydrogen-containing resin is selected as Saturated polyester polyol, amino alkyd polyol, polycarbonate ...

Example Embodiment

[0025] Example two

[0026] The second embodiment provides a two-component polyurethane coating consisting of component A and component B. The component A is calculated in parts by weight and includes the following components: 10 parts of acrylic resin dispersion, ethylene glycol ethyl ether acetic acid 6 parts of ester, 9 parts of resin containing active hydrogen, 15 parts of filler, 10 parts of chitin derivative formaldehyde removal auxiliary, 4 parts of anti-settling agent, 3 parts of defoamer, 3 parts of drier; B component is by weight In parts, it includes the following components: 13 parts of isocyanate and 12 parts of toluene diisocyanate trimer.

[0027] In this embodiment, the active hydrogen-containing resin is epoxy polyol; the filler is a mixture of talc and calcium carbonate, and the mass ratio of the two is 1:1; the anti-settling agent is organic bentonite; the defoaming agent is dimethyl Silicone oil; drier is dibutyl tin dilaurate.

Example Embodiment

[0028] Example three

[0029] The third embodiment provides a two-component polyurethane coating consisting of component A and component B. The component A is calculated in parts by weight and includes the following components: 7 parts of acrylic resin dispersion, ethylene glycol ethyl ether acetic acid 5 parts of ester, 7 parts of resin containing active hydrogen, 13.5 parts of fillers, 8.5 parts of chitin derivative formaldehyde removal auxiliary, 2 parts of anti-settling agent, 1.5 parts of antifoaming agent, 2 parts of drier; component B is by weight In parts, it includes the following components: 10 parts of isocyanate and 11 parts of toluene diisocyanate trimer.

[0030] In this embodiment, the active hydrogen-containing resin is saturated fatty acid alkyd resin; the filler is talc; the anti-settling agent is organic bentonite; the defoaming agent is dimethyl silicone oil; the drier is dibutyltin dilaurate.

Abstract

The invention provides a bi-component polyurethane coating, and relates to the field of coating. The bi-component polyurethane coating is composed of a component A and a component B. The component A comprises, by weight, 5-10 parts of acrylic resin dispersoid, 4-6 parts of glycol ether acetate, 5-9 parts of resin containing active hydrogen, 12-15 parts of padding, 8-10 parts of chitin derivative formaldehyde removal additives, 1-4 parts of anti-settling agents, 1-3 parts of defoaming agents and 2-3 parts of dryer. The component comprises, by weight, 7-13 parts of isocyanate and 10-12 parts of toluene diisocyanate capable. The bi-component polyurethane coating can reduce harm to the environment and the human body effectively and is suitable for being widely popularized.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a two-component polyurethane coating. Background technique [0002] With the rapid development of my country's economic construction, the quantity, variety and quality of coating production have changed greatly, but due to the needs of functions and the actual needs of the objective market, solvent-based coatings still occupy a large market share. However, traditional solvent-based coatings contain a large amount of organic solvents, which have caused some damage to the environment. In addition, after the paint is painted, the paint will release some harmful substances, such as formaldehyde, which will cause great harm to the human body. Contents of the invention [0003] In view of this, the present invention provides a two-component polyurethane coating to improve the problem that existing coatings cause certain harm to the environment and human body. [0004] To achieve the above o...
