Abstract

The invention discloses combined equipment for preparing a polymer compound by a grinding method. The combined equipment comprises a fine crushing subassembly device I provided with a normal-temperature millstone type elastomer fine crusher, or the combination of the fine crushing subassembly device I and one or more than one of the following known assembly devices which are also taken as subassembly devices: a cleaning assembly device II for washing, floating, dehydrating and drying waste plastics, a coarse crushing assembly device III for crushing an elastomer until the particle size is 5 to 30 meshes, a thermal cracking assembly device IV for waste rubber and plastic, and a separation assembly device V with a high-voltage electrostatic field separator. By the combined equipment, the defect that by the conventional hot melt extrusion method, waste plastics and thermoplastic elastomers are inevitably scorched and fume to be degraded when heated for a long time is overcome; and by the scheme, the problem that infusible large particle impurities easily block a net when regenerated miscellaneous waste plastics are hot-extruded to form products is also solved because the infusible large particle impurities in the material are ground.

Description

technical field [0001] The invention belongs to the field of chemical industry, and relates to the technology of rubber and plastic (including thermoplastic elastomer) composite material processing and regeneration processing equipment, especially suitable for the combination of elastomer or / and plastic grinding finely at normal temperature to prepare polymer composites equipment. technical background [0002] In the current technology of compounding elastomers and new plastics into rubber-plastic composites, if the selected elastomers are cured vulcanized rubber, etc., they must first be crushed or / and replasticized; The operation of filling thermoplastic elastomers and plastic materials with powder fillers requires the use of high-speed agglomerators, or combined machinery consisting of agglomerators, open mixers, internal mixers, and screw extruders. ℃ or higher temperature and under the condition of pinching shear force, using these machines to carry out the powder eati...
