Abstract

The invention discloses a processing method for preparing modified plastic rubber through utilizing waste plastic and waste rubber. The processing method is characterized by comprising the following technological steps: (1) selecting raw materials, namely by weight percent, respectively selecting 30-40% of waste rubber which is obtained by crushing waste styrene butadiene rubber (SBR) (synthetic rubber which is prepared by polymerizing styrene and butadiene emulsion), 15%-20% of wood meal and 55-60% of industrial waste sand as the raw materials, wherein each 100 kilograms of the raw materials contain 5 kilograms of waste oil and the industrial waste sand contains waste plastic, pulverized fuel ash and calcium carbonate; (2) crushing and grinding; (3) stirring and smelting; (4) melting and mixing; (5) forming; (6) classifying and packaging; (7) forming plate products. The processing method is reasonable and simple in technology, the technological process is greatly shortened, the production cost is lowered, and the yield is increased; the formed particles have smooth surfaces, so that dust production is reduced or eradicated in feeding and mixing processes during the production; the processing method satisfies the requirements of a production technology, is accurate in feeding amount and ratio, generates small deviation and ensures the product quality, and the yield of enterprises is effectively improved.

Description

technical field [0001] The invention relates to a manufacturing process of plastic materials, in particular to a processing method for making modified plastics from waste plastics and waste rubber. Background technique [0002] At present, plastics have been widely used in the construction industry, packaging materials, household daily necessities and automobiles and other fields. Because of its wide range of uses and good performance, plastics constitute one of the four basic materials of modern industry together with steel, wood and cement. With the continuous expansion of industrialized production, especially the rapid development of coal and thermal power industries, some industrial wastes continue to increase, which has brought serious environmental pollution to the society. Waste plastics and fly ash have caused serious "white pollution" And "black pollution", endangering people's quality of life and restricting the development of the national economy, has become a wo...
