Bumper strip production method

Abstract

The invention relates to a bumper strip production method. A bumper strip is made of ethylene-propylene-diene-terpolymer rubber, and the method includes the steps: subjecting the ethylene-propylene-diene-terpolymer rubber to extrusion molding by the aid of an extruder, vulcanizing the bumper strip by salt bath equipment, and dragging the bumper strip to pass through liquid-state industrial salt through a conveying belt in the salt bath equipment, so that the bumper strip is in the suspension state in the liquid-state industrial salt; washing salt on the surface of the bumper strip by the aid of hot water after the bumper strip comes out of the liquid-state industrial salt, patting the bumper strip by the aid of a rotating crossbar in the salt bath equipment during washing to lead the salt and water on the surface of the bumper strip to shake off, and then outputting the bumper strip through the conveying belt; and sequentially washing the surface of the bumper strip with hot water in four channels and cold water in one channel, sweeping residual salt on the surface of the bumper strip by a salt sweeping device after washing in each channel, blowing away the water and the salt on the surface of the bumper strip by an air knife, conveying the bumper strip to a dryer to be directly dried, cooling the bumper strip by cold air by the aid of the air knife after the bumper strip is dried, and finally rolling the bumper strip to a disk so that a finished product is obtained.

Description

technical field [0001] The invention relates to the field of production of anti-collision strips, in particular to a production method of anti-collision strips. Background technique [0002] In the existing anti-collision strip production process, the newly extruded anti-collision strip is heated and vulcanized by hot air, but because the anti-collision strip needs to walk on the conveyor belt during the hot-air vulcanization process, it is easy to produce some Scratches and slight extrusion deformations affect the quality and quality of the anti-collision strips. At the same time, it is difficult to control the temperature of the hot air heating so that each part can reach an accurate value, so that the anti-collision strip is heated unevenly and affects its vulcanization effect. Contents of the invention [0003] The object of the present invention is to provide a kind of anti-collision strip production method with low production cost and good production effect in order...

[0002] In the existing anti-collision strip production process, the newly extruded anti-collision strip is heated and vulcanized by hot air, but because the anti-collision strip needs to walk on the conveyor belt during the hot-air vulcanization process, it is easy to produce some Scratches and micro-extrusion deformations, which affect the quality and quality of the anti-collision strip

At the same time, it is difficult to control the temperature of the hot air heating so that each part can reach an accurate value, so that the anti-collision strip is heated unevenly and affects its vulcanization effect.
