Problems solved by technology

[0002] Paint is a widely used paint. Most of the existing paints use synthetic resin as the main film-forming material and are formulated with a variety of raw materials. The process is complicated and the cost is high.
However, a large number of discarded synthetic resin plastic products pollute the environment, and it is very difficult to deal with them. Whether it is possible to turn waste plastics into treasures, recycling is the direction of people's efforts.

Embodiment 1

[0006] Embodiment 1, 70 kilograms of polystyrene foams and 15 kilograms of ethanol, 18 kilograms of acetone are mixed and stirred, and after precipitation removes impurity, obtain varnish in 4 hours.

Embodiment 2

[0007] Example 2, 20 kg of polyvinyl chloride waste plastics, 20 kg of ethanol, and 16 kg of acetone were mixed and stirred, and heated to 80 ° C at the same time. After precipitation and removal of impurities, the varnish was obtained in 1 hour.

Embodiment 3

[0008] Embodiment 3, with 30 kilograms of polystyrene, 30 kilograms of polyethylene waste plastics and 20 kilograms of ethanol, 20 kilograms of acetone are mixed and stirred, and after reprecipitating for 4 hours, after separating the impurities and dirt on the surface of waste plastics that have not been cleaned, The obtained varnish is ground by a three-roll mill to obtain a varnish meeting the national standard, and after adding dyes and mixing, it can be made into paints of various colors.

Abstract

The present invention relates to a production process of converting waste polystyrene and other waste plastic directly into paint. Waste plastic, ethanol and acetone in the weight rati oof 6-7 to 1.5-2 to 1.5-2 are mixed with stirring, and deposited and separated to eliminate impurity to prepare paint. During the production, the mixture may be heated to shorten the convension period. The said process can produce paint at low cost and converting waste into useful material to protect environment.

Description

technical field [0001] The present invention relates to a method for the preparation of paints. Specifically, it is a method of converting waste plastics into paints. Background technique [0002] Paint is a widely used paint. Most of the existing paints use synthetic resin as the main film-forming material and are formulated with various raw materials. The process is complicated and the cost is high. However, a large number of discarded synthetic resin plastic products pollute the environment and are very difficult to deal with. Whether waste plastics can be turned into treasures, recycling is the direction of people's efforts. Contents of the invention [0003] The present invention is to transform and produce a large amount of discarded synthetic resin waste plastics into paints (varnishes, base paints). The method of the invention is to mix and stir waste plastics, ethanol and acetone according to the weight ratio of 6-7: 1.5-2: 1.5-2, dissolve, react and convert at ...
