Abstract

The invention belongs to the technical field of macromolecules and in particular relates to a thermoplastic elastic material for manufacturing an extrusion tube and a preparation method of the thermoplastic elastic material. The thermoplastic elastic material for manufacturing the extrusion tube comprises the following raw materials in parts by weight: a hydrogenated styrene-ethylene-butadiene-styrene polymer, processed paroline, polypropylene, a polyolefin elastomer and aids. The preparation method for preparing a thermoplastic elastic material for a non-pneumatic tire comprises the followingsteps: (1) mixing the raw materials according to a ratio, and uniformly stirring at a room temperature so as to obtain a mixed material; (2) feeding the mixed material into an extruder at a constantspeed, wherein the extruder is provided with ten heating zones; (3) carrying out extrusion, and carrying out pelletizing. The thermoplastic elastic material for manufacturing the extrusion tube, whichis provided by the invention, is high in surface elasticity, high in rebound resilience, high in fatigue resistance and aging resistance, high in elongation rate and high in wearing resistance, pressure resistance and tension resistance, and the preparation method provided by the invention is simple in process, easy to operate and high in product pass percent.

Description

technical field [0001] The invention belongs to the technical field of polymers, and in particular relates to a thermoplastic elastic material used for making extruded pipes and a preparation method thereof. Background technique [0002] As an important part of chemical building materials, plastic pipes are widely accepted by users for their superior performance, sanitation, environmental protection, and low consumption. They mainly include UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes, and polyethylene (PE) pipes. These are the water supply pipes. [0003] However, the pipes currently on the market have poor surface elasticity and resilience, are easily deformed, and have poor compression resistance. Contents of the invention [0004] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to provide a thermoplastic elastic material for making extruded tubes; another object of the pr...
