Novel composite powder of rubber substituent FA for substituting rubber to produce wound clutch facing

Abstract

The invention discloses a novel composite powder of rubber substituent FA for substituting rubber to produce a wound clutch facing, which aims to solve the problems of consumption of disposable resource of petroleum, complex process, high production cost, hidden danger of safety and environment, 'three hot' of products and the like in the conventional method of producing the wound clutch facing by using rubber. The novel composite powder of rubber substituent FA is prepared by mixing polysaccharide powder, a stabilizing material, a coloring agent and an isolation material in a blender mixer according to a certain ratio, dosing sequence and dosage for a certain period of time. The novel composite powder of rubber substituent FA for producing the wound clutch facing has the characteristics of energy conservation, consumption reduction, environmental protection, sustainable development and the like, and has obvious economic and social benefits.

Description

technical field [0001] The present invention is a new type of compound powder-replacement rubber FA for replacing rubber to produce winding clutch face and its preparation method, which belongs to chemical binder, relates to the technical field of polymer composite materials and friction materials, and is used to replace rubber to produce winding clutch face . Background technique [0002] At present, with the gradual depletion of disposable resources such as petroleum in the world, the raw materials related to the production of clutch faces for motor vehicles, such as styrene-butadiene rubber, phenolic resin, gasoline (solvent), alcohol (solvent), and other resources are very tight. The rising price has brought serious survival crisis to the enterprise. In addition, according to the current situation of using rubber to produce wound clutch faces, in order to meet the product performance and production process requirements, it is necessary to use phenolic resin bonding mate...

AI Technical Summary

Problems solved by technology

[0002] At present, with the gradual depletion of disposable resources such as petroleum in the world, the raw materials related to the production of clutch faces for motor vehicles, such as styrene-butadiene rubber, phenolic resin, gasoline (solvent), alcohol (solvent), and other resources are very tight. Prices continue to rise, bringing serious survival crisis to enterprises

In addition, according to the current situation of using rubber to produce wound clutch faces, in order to meet the product performance and production process requirements, it is necessary to use phenolic resin bonding materials at the same time, and the solvents used for the two materials of rubber and phenolic resin are gasoline and alcohol respectively. , the particularity of incompatibility between them determines that the second impregnation method must be adopted (that is, the various cloths or threads used are impregnated with liquid phenolic resin for the first time, and then the resin cloth or threads are soaked after drying. impregnated with rubber glue to make tape or thread, and then processed through a series of processes such as tearing cloth, winding, hot pressing, etc., to make a clutch face for motor vehicles), the production process is complicated and the cost is high

At the same time, due to the use of alcohol, rubber and gasoline, there are flammable and explosive safety hazards and environmental protection hazards

Furthermore, a relatively large amount of rubber binder is used in the clutch face. Due to the poor heat resistance of the rubber, this type of product cannot meet the performance requirements of the clutch face for automobiles, resulting in the existence of "thermal recession, thermal expansion" in the product. , thermal cracks and other three heat and short service life and other issues
