Problems solved by technology

[0002] Plastic granules are processed from high-pressure polyethylene (PE), generally imported from Italy, Japan, South Korea, Europe and the United States, and processed in China. They are widely used in clothing industry, building materials, agriculture, machinery industry, etc. Application, recycled granules are a kind of plastic granules, which can be used to make various plastic bags, barrels, basins, toys, furniture, stationery and other living utensils and various plastic products, which play an important role in life. Nowadays, plastic granules The production is generally made of new high-pressure polyethylene (PE), which has high processing costs, high production efficiency, and low product income.

Abstract

The invention discloses a method for preparing high-valued recycled plastic particles by utilizing recycled garbage films. The method comprises the following steps of selecting PE / PP materials from the recycled garbage films, and removing composite films / films with aluminum foils; washing the sorted plastics with water, and adding chemicals to remove oil stains and dirt; crushing cleaned plastic, arranging a stirrer in a crusher, and performing crushing while performing stirring, so that enabling the crushing to be more thorough; rinsing the crushed plastic; drying the rinsed plastic; and adding auxiliaries into the dried plastic, mixing, conveying into a plastic extruder, molding, and finally carrying out traction granulation. According to the method, an appropriate treatment method is provided for utilization of the waste plastic films, the waste plastic films can be harmless and can be recycled, the utilization rate of an added anti-aging agent and anti-ultraviolet agent is high, and the obtained regenerated particles have good aging resistance.
