Problems solved by technology

However, there are no industrialized water-based plastic coating products in China at present, mainly because: 1. The performance does not meet the requirements of the manufacturer, such as appearance, hardness, alcohol resistance, etc.; 2. The drying performance is not good, too slow (generally required 70°C x 30 minutes or more demanding process, solvent-based coatings are generally around 50°C x 10 minutes), which seriously affects the customer's equipment utilization efficiency and site utilization efficiency

Abstract

The invention discloses a water-based paint for quick-drying alcohol-resistance plastics, comprising the following components by weight parts: 20-80 parts of modified polyacrylic ester water dispersoid, 1-25 parts of coloring pigment paste, 0-10 parts of filler pump, 5-25 parts of film formation assistant, 0.5-10 parts of assistant for water-based paint, and 10-50 parts of water. The invention further discloses a preparation method of the water-based paint, comprising the following steps: the water, the film formation assistant, polymer water dispersoid resin and the assistant for partial water-based paint are added in a make-up tank and are stirred uniformly, and then the coloring pigment paste and the assistant for the remaining partial water-based paint are sequentially added in and are stirred uniformly, the viscosity and pH value are regulated, filtering and discharging are carried out to obtain the water-based plastic paint finished products. The water-based paint is used for coating surface of the plastics, so as to achieve good decoration effect; in addition, the performance of the water-based paint is equivalent to that of solvent plastic paint, the water-based paint has good alcohol resistance and can be dried at 50 DEG C for 10 minutes, so as to meet the process requirements of manufacturers who use the solvent plastic paint at present.

Description

technical field [0001] The invention relates to a chemical coating, in particular to a quick-drying and alcohol-resistant water-based coating for plastics, and also relates to a preparation method of the coating. Background technique [0002] With the development of modern industry, plastic, as a new type of material, has widely replaced traditional materials such as wood and steel for various industries, such as: automobiles, home appliances, construction and other commercial purposes. In order to be beautiful and durable, it is often necessary to use paint for coating. The coatings used for plastic coating in the early days were all solvent-based coatings, that is, containing a large amount of organic solvents, and were used for plastics, especially polar plastic substrates such as polycarbonate, polyamide, ABS, HIPS, etc. As we all know, the disadvantages of solvent-based coatings are waste of energy, resources and serious environmental pollution caused by a large amount...
