Embodiment 1

[0017] A kind of polyester acrylate antibacterial UV paint of the present invention, this polyester acrylate antibacterial UV paint is made up of following proportioning composition of parts by weight: 110 parts of adipic acid, 10 parts of maleic anhydride, trimethylol propane 90 parts, 311 parts of neopentyl glycol, 2 parts of catalyst, 0.5 parts of antioxidant, 80 parts of xylene, 44 parts of water, 3 parts of water-based dispersant, 35 parts of calcium carbonate, 29 parts of talc, 1.6 parts of water-based defoamer 1.5 parts, 1.5 parts of thickener and 1.5 parts of film-forming aid.

[0018] The preparation process of described polyester acrylate antibacterial UV coating is as follows:

[0019] 1) Extract 110 parts of adipic acid, 10 parts of maleic anhydride, 90 parts of trimethylolpropane, and 311 parts of neopentyl glycol according to the weight ratio and put them into a reactor for mixing, heat to 110°C and stir evenly;

[0020] 2) Extract the mixture in step 1, dischar...

Embodiment 2

[0027] It differs from Example 1 in that the polyester acrylate antibacterial UV coating is made up of the following proportioning components in parts by weight: 80 parts of adipic acid, 5 parts of maleic anhydride, 60 parts of trimethylolpropane, 200 parts of neopentyl glycol, 0.5 parts of catalyst, 0.1 part of antioxidant, 60 parts of xylene, 33 parts of water, 0.4 parts of water-based dispersant, 13 parts of calcium carbonate, 22 parts of talcum powder, 0.6 parts of water-based defoamer, Thickener 0.1 part and film-forming aid 0.5 part.

Embodiment 3

[0029] It differs from Example 1 in that the polyester acrylate antibacterial UV coating is made up of the following proportioning components in parts by weight: 90 parts of adipic acid, 8 parts of maleic anhydride, 70 parts of trimethylolpropane, 250 parts of neopentyl glycol, 1.5 parts of catalyst, 0.3 parts of antioxidant, 70 parts of xylene, 38 parts of water, 2 parts of water-based dispersant, 22 parts of calcium carbonate, 27 parts of talcum powder, 1.2 parts of water-based defoamer, 1.1 parts of thickener and 1.1 parts of film-forming aid.

Abstract

The invention discloses a polyester acrylate antibiosis UV coating and a preparation method thereof. The polyester acrylate antibiosis UV coating is prepared from, by weight, 80-110 parts of hexanedioic acid, 5-10 parts of maleic anhydride, 60-90 parts of trimethylolpropane, 200-311 parts of neopentylene glycol, 0.5-2 parts of a catalyst, 0.1-0.5 parts of an antioxidant, 60-80 parts of xylene, 33-44 parts of water, 0.4-3 parts of an aqueous disperser, 13-35 parts of calcium carbonate, 22-29 parts of talcum powder, 0.6-1.6 parts of an aqueous antifoaming agent, 0.1-1.5 parts of a thickener and 0.5-1.5 parts of a film forming assistant. Polyester acrylate resein is adopted in the preparation process of the polyester acrylate antibiosis UV coating, and the polyester acrylate resin has low viscosity and flexibility, so the coating has the advantages of fast solidification speed, good flexibility, strong adhesion, low shrinkage, no peculiar smell, high scratch resistance, high chemical resistance and good antibiosis effect.

Description

technical field [0001] The invention relates to a polyester acrylate antibacterial UV coating and a preparation method thereof. Background technique [0002] UA coatings are widely used and can be used to finish the surface of various electronic products. But, in daily life, along with the aggravating of environmental pollution, various bacteria, germ are easy to breed and multiply, especially for the household appliances and electronic products that human body often contacts. Electronic products have been widely used in people's daily life. During storage and use, there will be a certain amount of bacteria on the surface. Existing paint coatings do not have antibacterial and bactericidal effects, and people often need to use additional bactericidal methods frequently, which is very inconvenient. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a polyester acrylate antibacterial UV coating with fast curing speed...
