Abstract
A kind of no copper stibium-free environment-friendly ceramic frication material and preparation method thereof, using 6-9 parts of phenolic resin, 2-4 parts of Frication powder, 3-6 parts of aramid fiber, 15-25 parts of titanate lamella, 3-6 parts of carbon fiber, 4-8 parts of mineral fibres, 4-7 parts of honeycomb graphite, 3-6 parts of petroleum coke, 8-12 parts of zirconium silicate, 8-12 parts of iron oxide black, without 6-10 parts of antimony sulfide, 2-4 parts of nitrile rubber powder, 3-6 parts of mica, 10-25 parts of barite.Whole mixture is suppressed at 150-160 DEG C in hot pressing grinding tool, pressing pressure 25-35Mpa, the pressing time is 5-7 minutes；Then heat treatment 4-6 hours is carried out under conditions of 180-220 DEG C, finally takes out friction material grinding and finished product is made.The present invention is produced for no copper without the brake block of antimony, and copper, stibium heavy metal ingredient is avoided to be drained into environment, reduces pollution on the environment and the injury to biology.
Description
Technical field
The present invention relates to a kind of no copper stibium-free environment-friendly ceramic frication materials and preparation method thereof, belong to friction material preparation
Technical field.
Background technique
Brake block is the important brake component of automobile, and ensures the important component of driver safety.We are made at present
Contain many heavy metal substances in the friction material of automotive brake pads, including copper, antimony, chromium, cadmium, lead metal etc..And
The meeting in Motor Vehicle Braking Procedure of these substances and is accumulated and is caused in the environment to human body so that a small amount of heavy metal dusts discharge
Harm.If lead and its compound all have certain toxicity, into body after to nerve, hematopoiesis, digestion, kidney, angiocarpy and
Multiple systems such as endocrine generate harm.The personnel of operation contain with internal antimony under low concentration antimony and its chemical combination substance environment for a long time
Antimony slow poisoning may occur for the slowly increase of amount.The chronic toxicity test of antimony and its compound confirms, in antimony and cell
Irreversible combination occurs for sulfydryl, and then interferes the eubolism containing thiol protein and enzyme, to generate to organism
Detrimental effect is mainly shown as lung function change, chronic bronchitis, pulmonary emphysema, incipient tuberculosis, pleaural adhesion and pneumoconiosis
Disease.And cupric dust can cause very big harm to biology and soil after entering environment.
It is proved according to relevant information, 30% Cu-W ore deposit is as caused by automotive brake pads in environment.Therefore it stops for automobile
Vehicle piece is influenced to caused by environment, we have to be paid attention to.Since on January 1st, 2015, in the brake of State of Washington sale
Vehicle friction material its asbestos fibre, cadmium, chromium, lead or mercury content must not exceed 0.01% (by weight).From January 1 in 2021
Day rises, and the copper or copper compound content in the brake friction material of Washington sale must not exceed 5% (by weight).The mark
Standard is suitable for brake block manufacturer, whole seller, dealer, installation quotient and retailer, and the vapour in State of Washington selling automobiles
Vehicle manufacturer.Meanwhile Advisory Board has been set up in industry, safety, environmentalist, research and assessing will limit the content of copper in future
Make the feasibility 0.5%.Therefore it needs to research and develop a kind of technical solution of no copper stibium-free environment-friendly ceramic frication material.
Summary of the invention
The present invention is in view of the deficienciess of the prior art, provide a kind of no copper stibium-free environment-friendly ceramic frication material and its system
Preparation Method can be used in no copper and produce without the brake block of antimony, the copper in brake block, stibium heavy metal ingredient is avoided to be drained into environment,
Reduce pollution on the environment and the injury to biology.
The technical scheme to solve the above technical problems is that a kind of no copper stibium-free environment-friendly ceramic frication material,
The parts by weight of raw material and raw material components that the friction material includes are as follows:
6-9 parts of phenolic resin, 2-4 parts of Frication powder, 3-6 parts of aramid fiber, 15-25 parts of titanate lamella, carbon fiber 3-6
