Problems solved by technology

[0018] Aiming at the shortcomings of the existing technology, the dust pollution is serious during the regeneration process of old discarded elastomers (that is, rubber or / and plastic) or / and plastic polymer materials, and high-efficiency continuous production cannot be achieved, and the existing recycled rubber 1. Plastic products have coarse particle size, poor physical properties, and the old discarded rubber and plastic products are not easy to mix in the regeneration process. A targeted solution is proposed; it is also proposed to use the commercially available reclaimed rubber with low physical properties and other secondary Raw rubber, reprocessed to improve physical properties

Abstract

The invention discloses a new regenerating method of waste elastics and plastic, which comprises the following steps: 1. blending waste elastics or / and plastic with grain size between 5 and 80 order and non-polluted regenerative adjuvant according to proportion; placing into the manufacturing machine; grinding; sieving; heating to desulfurize; bulking; soaping; emulsifying; kneading; pressing; graining; obtaining composite product 1 with mother material or mother particle or mother gel of plastic elastic powder; 2. weighing product 1 and non-polluted mating agent into mixing machine according to proportion; kneading; blending evenly; pressing; graining; obtaining the product 2 of mother material or mother particle or mother gel with 5-95% waste elastic or / and plastic.

Description

technical field [0001] The invention mainly relates to the environmental protection collaborative recycling of used elastic bodies, plastics and other solid wastes, etc., and belongs to the technical category of waste recycling. Background technique [0002] The recycling of solid waste such as old and discarded elastomers and plastics is an indispensable industrial category for my country, a large developing country. The regeneration of used and discarded elastomers and plastics is usually classified as In the waste rubber recycling industry and the waste plastic recycling industry, they are two industries that do not interact with each other. [0003] At present, the main products in the waste rubber recycling industry (accounting for more than 80% in our country) - reclaimed rubber and the newly developed fine rubber powder in recent years, have always had many defects that hinder the survival or development of their products!
