Water-based environment-friendly polyethylene plastic paint accelerator and preparation method thereof

Abstract

The invention discloses a water-based environment-friendly polyethylene plastic paint accelerator and a preparation method thereof. The accelerator consists of the following components in percentagesby weight: 22%-27% of solid thermoplastic polyolefin resins, 3%-8% of solid darma resins, 8%-17% of 2-butanone, 3%-6% of isopropanol, 29%-52% of methylcyclohexane, 5%-10% of emulsifiers, 4%-8% of amylacetates and 5%-11% of oxidized starch. The water-based environment-friendly polyethylene plastic paint accelerator can be directly sprayed on polyethylene (PE) plastics at one time, and can still obtain excellent adhesion under the condition of no flame or corona treatment, produce wear-resistant, heat-resistant and water erosion-resistant paint films and realize simple and easy praying, thus saving manpower and material resources and time. The accelerator is simple in preparation process, low in price, good in workability and low in environmental pressure, so that the accelerator is convenient for large-scale industrial production, with broad market prospects.

Description

technical field [0001] The invention belongs to the field of equipment manufacturing, and more specifically relates to a water-based environment-friendly polyethylene plastic paint accelerator. At the same time, the invention also relates to a preparation method of a water-based environment-friendly polyethylene plastic paint accelerator. Background technique [0002] Due to its many advantages such as environmental protection, durability and lightness, PE plastics are increasingly widely used in automobiles, engineering plastics, toys, containers, other molded parts and packaging films. In order to modify and protect these plastic products, they are usually painted with a layer of paint or printed with beautiful artistic patterns. [0003] At present, due to the poor conductivity of plastic products, it is necessary to coat a layer of conductive primer on the entire plastic surface in electrostatic spraying before spraying the topcoat. At the same time, due to the process...

Problems solved by technology

At the same time, due to the process of electrostatic spraying, many plastic coatings with chemical resistance (hand sanitizer, detergent, facial cleanser and other daily chemicals) will cause the surface of the paint film to be rough and uneven in color during electrostatic spraying, and the effect is poor. to customer requirements

[0004] It is very difficult to bond paint and printed patterns on plastic, and the coating for PE (polyethylene) is the most difficult, and these problems have not been well solved.

Now many manufacturers use imported chlorinated polypropylene resin as PE accelerator, the adhesion effect is not ideal, and it is not environmentally friendly because it contains chlorine
