Special material for pass box for regenerating and modifying waste bottle cap crushed plastic, and preparation method of special material

Abstract

The invention discloses a special material for a pass box for regenerating and modifying waste bottle cap crushed plastic, and a preparation method of the special material. The special material and the preparation method solve the problems that the special material for the pass box is high in production cost and complicated in production technique in the prior art. The special material comprises the following components in parts by weight: 100 parts of waste bottle cap crushed material, 2-5 parts of EVA (Ethylene-Vinyl Acetate), 3-8 parts of flexibilizer, 5-10 parts of activated talcum powder, 0.1-2 parts of dispersing agent and 0.1-1.5 parts of modifier, wherein the waste bottle cap crushed material is obtained by crushing, cleaning, rinsing, drying and absorbing the recovered waste bottle cap crushed plastic. The invention further provides the preparation method of the special material for the pass box for regenerating and modifying the waste bottle cap crushed plastic. The special material and the preparation method can recycle the waste bottle cap crushed plastic effectively, and have the advantages that resources are saved, an environment is protected, the cost is lowered, and the preparation process is simplified.

Description

technical field

[0001] The invention specifically relates to a special material for recycled and modified turnover boxes of broken plastics from waste bottle caps and a preparation method thereof. Background technique

[0002] At present, many enterprises have begun to mechanize the recycling of PET beverage bottles (Coke bottles) to increase the recycling rate, but the caps (PE materials) of the removed beverage bottles contain about 30%, and some of them are even higher. Most of these materials are used for bottom injection molding and less demanding products. The beverage bottle cap material is polyethylene plastic, but due to the process of mechanized recycling of beverage bottles, the removed bottle cap contains a large amount of polyester plastic (PET), PE is a non-polar plastic, and PET is a polar plastic. Poor compatibility, such as direct use often has poor performance, obvious weld marks and serious delamination. Contents of the invention
