Embodiment

[0045] (1) Its preparation method of aqueous vinyl chloride copolymer emulsion is as follows:

[0046] (1) monomer pre-emulsification

[0047] Weigh 120 parts of vinyl chloride, 80 parts of acrylate, 20 parts of crosslinking monomer, and 2 parts of nonylphenol polyoxyethylene ether as an emulsifier, put them into a pre-emulsification kettle and stir and emulsify for 2 hours to obtain a pre-emulsified monomer solution;

[0048] (2) Preparation and addition of additives

[0049] Get 160 parts of deionized water, 4 parts of emulsifying agent sodium lauryl sulfate, 1.6 parts of sodium bicarbonate, 1 part of glue-preserving agent polyvinylpyrrolidone and add in the pre-emulsification kettle of step (1) after fully stirring and dissolving; Take initiator 1 part of ammonium persulfate is dissolved in 80 parts of water for subsequent use;

[0050] (3) Polymerization reaction

[0051] Take 1 / 3 volume of the mixed solution in the step (2) pre-emulsification tank and 1 / 4 volume of the...

Abstract

The invention relates to the technical field of coatings, in particular to a water-based environment-friendly vinyl chloride plastic paint and a preparation method thereof. The invention provides a water-based environmentally friendly vinyl chloride plastic paint, which solves the problems of high VOC content, poor alignment of silver powder, poor water resistance, poor chemical resistance and slow drying speed of the plastic paint used in the electric bicycle industry. As a one-component coating, vinyl chloride plastic paint has fast drying speed, good stability, convenient construction, good water resistance and chemical resistance, and the silver powder is well oriented and can be seamlessly connected with the top coat.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based environment-friendly vinyl chloride plastic paint and a preparation method thereof. Background technique [0002] With the development of science and technology, electric bicycles have developed rapidly due to the advantages of convenience, environmental protection, and economy. Most of the appearance parts of electric bicycles are plastic parts such as ABS. In order to achieve the effect of protection and decoration, these plastic parts must be surface coated. . [0003] At present, the plastic coatings used in the electric bicycle industry are still mainly solvent-based, and a large amount of volatile solvents during construction will cause serious harm to the environment and human health. For example, Chinese invention patent CN 102352157 A discloses a chemical-resistant plastic coating. Composed of the following components: thermoplastic acrylic resin 10-30%, ...
