Abstract
The present invention belongs to the field of automobile friction composite material. Said invention product can substitute for original asbestos product. Said invention is aimed at selecting glass fibre which has good frictional property, excellent temperature-resisting property and low cost as main raw material, at the same time adding special chemical fibre with good spinnability and temperature-resisting property so as to make the automobile friction material have higher high-temperature frictional-coefficient lower abradability and higher strong force under the condition of high speed. Said invention adopts special friction spinning machine to produce non-asbestos friction material with special core-covering structure.
Description
The invention belongs to the automotive friction field of compound material, can replace original asbestos product with product of the present invention, is a kind of weaving composite friction material of novel environment-friendly.
Traditional automobile composite friction material is to adopt fibrous magnesium silicate to do main raw material.Fibrous magnesium silicate is very big to the harm of human body, can be trapped in for a long time in the human body, causes canceration.The dust that asbestos brake lining and clutch disc produce when automobile operation contains the asbestos powder, also has a large amount of dust to produce in producing the process of these products, is easy to be sucked by human body, and that causes lung and tracheae sternly gets disease.Asbestos friction material can not satisfy Hyundai Motor high speed, high-intensity frictional behaviour requirement simultaneously.China has taken up to formulate the rules of forbidding producing and using asbestos material, estimates to implement in 2004.Western developed countries such as America and Europe have been prohibited the automobile friction materials of producing and using asbestos material to make.Press at present can satisfy heatproof, frictional coefficient is good, wear rate is low, and a kind of asbestos replace product.Yet there are no the report of this series products.
The objective of the invention is to select for use frictional behaviour is good, heat resistance is superior, cheap glass fibre as main raw material; Be aided with good spinnability, the good special chemical fiber of heat resistance simultaneously, make the high temperature friction coefficient of automotive friction material better, wear rate is lower, the brute force under the high-speed condition is higher.Non-asbestos friction material with the special packet cored structure of special-purpose friction spinning machine production has solved the needs of environmental protection and Hyundai Motor industry simultaneously.
Master of the present invention is in content:
1, the composition of raw material: glass fibre, copper wire, chemical fibre (acrylic fibers, viscose glue, aramid fiber or preoxidation acrylic fibers etc.)
2, operational path:
The mixing of several raw materials---shredding---unclog and readjust---spinning---(weave cotton cloth---) impregnation
3, the key technical indexes of resultant yarn
Composite yarn density 1750Tex
Core yarn cloth through close 28 ± 2/10cm
Ablation amount＜35%
Tensile strength＞0.08N/Tex
Frictional coefficient＞0.45/300 ℃
The present invention compared with prior art has and has following advantage:
Product of the present invention is a non-asbestos friction material, has thoroughly solved fibrous magnesium silicate to environment, to the difficult problem of mankind's harm.
The glass fibre core yarn is the high-grade friction materials of frictional behaviour the best in the present non-asbestos friction material.
Its principle is because due to the special construction of its core yarn.The core of core yarn is made up of filament of glass fiber and copper wire; Outsourcing glass fibre short fiber and heatproof man-made fiber.Outer wrapping fiber perpendicular to frictional direction, has played conclusive effect to the frictional coefficient of friction plate in automobile friction.
The physics of glass fibre and chemical property have determined its spinning performance extreme difference, as: proportion, elongation, the elasticity amount of rubbing, moisture regain, static and bending property.Especially difficulty is very big in the process of shredding, combing, drawing-off, twisting.Though added the spinning that a certain amount of heatproof man-made fiber comes the auxiliary glass fiber, the content of glass fibre and which kind of man-made fiber of selection are the principal elements of the performance of decision friction materials.
The present invention opens up a new developing direction for idle FRICTION SPINNING equipment, has driven the development of technical textile, for society provides a large amount of job opportunities.
