Embodiment 1

[0025] A rubber manufacturing process, comprising the steps of:

[0026] (1) Preparation of raw materials

[0027] Put the raw materials into the buffer tank for mixing, then cool the mixed raw materials through low-temperature water, then pass through low-pressure propylene, and finally pass through low-pressure ethylene for further cooling. The temperature after cooling is -98°C. And the ratio is 90% of raw rubber, 3% of hard carbon black, 0.5% of antimony trioxide and 1.5% of strontium iron oxide powder;

[0028] (2) Catalyst preparation

[0029] solid AlCl 3 Make a saturated solution with methyl chloride in a dissolution tank, then mix the saturated solution with methyl chloride in a buffer tank to obtain a catalyst solution with a concentration of 0.1%, then pass through low-pressure propylene, and finally pass through ethylene for further cooling, the temperature after cooling -90°C-minus 100°C;

[0030] (3) Plasticizing

[0031] The prepared raw materials and catal...

Abstract

The invention discloses a rubber manufacturing technology. Raw materials comprise crude rubber, hard carbon black, antimony trioxide and strontium ferrite powder in proportion, so that produced rubber has the advantages of high strength, high magnetism and high flame resistance; the prepared raw materials and a catalyst are sent to the bottom and the middle of a polymeric kettle through flow regulators respectively, crude rubber generation can be promoted, colloidal particle bonding can be effectively prevented, the polymeric kettle is cleaned after polymerization, and accordingly, the problems of short service life and high production cost due to the fact oligomers are attached to the inner wall of the reaction kettle and form bonding rubber suspension can be solved; the rubber manufactured with the technology has the advantages of high static bending strength and high elasticity modulus, and has huge market potential and broad prospect.

Description

technical field [0001] The invention belongs to the field of rubber manufacturing, and more specifically, the invention relates to a rubber manufacturing process. Background technique [0002] Early rubber was latex taken from plants such as rubber trees and rubber grasses, which were processed into materials with elasticity, insulation, impermeability to water and air. High elastic polymer compound. Divided into two kinds of natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from rubber trees, rubber grass and other plants; synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in all aspects of industry or life. As a natural material, wood has the characteristics of low density, high specific strength and stiffness, easy processing, and renewable. The current rubber manufacturing process has the problems of low production efficiency and high production cost. Contents of the invention [000...
