Description

PTFE rubber composite production line
Technical Field
The invention relates to the technical field of rubber processing, in particular to a PTFE rubber composite production line.
Background
Polytetrafluoroethylene (Poly tetra fluoroethylene, abbreviated as PTFE), commonly known as "plastic king", is a high molecular polymer prepared by polymerizing tetrafluoroethylene as a monomer. White wax, semitransparent, heat-resistant and cold-resistant, and can be used for a long time at-180-260 ℃. The material has the characteristics of acid resistance, alkali resistance and resistance to various organic solvents, and is almost insoluble in all solvents. Meanwhile, polytetrafluoroethylene has the characteristic of high temperature resistance, and has extremely low friction coefficient, so the polytetrafluoroethylene can be used for lubrication, and also becomes an ideal paint for easily cleaning the inner layer of the water pipe.
The rubber is a high-elasticity polymer material with reversible deformation, is elastic at room temperature, can generate larger deformation under the action of small external force, and can recover after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature (T g) and often a large molecular weight, greater than several hundred thousand. Rubber is classified into natural rubber and synthetic rubber. The natural rubber is prepared by extracting colloid from plants such as rubber tree, rubber grass, etc.; the synthetic rubber is obtained by polymerizing various monomers. Rubber products are widely used in industry or life.
The PTFE rubber is a composite material formed by mixing and processing PTFE, rubber and other ingredients, and has excellent performances such as friction resistance, high elasticity and deformation resistance. The processing method of PTFE includes several modes of mould pressing, hydraulic pressure and pressing, etc., and the mould pressing and forming mostly adopts suspension resin as raw material, and the resin needs to undergo several procedures of feeding, mashing and screening before processing.
The existing PTFE rubber production technology has the following defects:
1. the suspension resin needs to be sequentially subjected to multiple working procedures such as feeding, mashing and screening before processing, and the working procedures are all independent, so that a large amount of time is wasted, and the efficiency of composite production is reduced.
2. After raw rubber is plasticated, the plasticated raw rubber needs to be manually transferred to the interior of the mixer, in the mixing process, a worker needs to directly stand on the mixer, and the ingredients are sequentially put on the raw rubber on the inner roller of the mixer, so that manpower is wasted, meanwhile, the manual feeding is easy to fatigue, the efficiency of the ingredients is reduced, and the worker needs to be frequently close to a rotating heating roller, so that the mixing machine has a certain potential safety hazard.
