Description
Technical field
The present invention relates to brake block technical field, the automobile-used disc brake pad friction material of especially a kind of heavy type and brake block
Preparation process.
Background technique
With the fast development of world economy, the demand to logistics is also increasing.Highway transportation is fast as a kind of convenience
Prompt and moderate means of transportation, also increasingly by everybody favor.As the main carrier of highway transportation, heavy duty
Vehicle to possess quantity also increasing.Since heavy duty vehicle load is big, the requirement to braking system is relatively high, especially exists
In the case where the complex road condition of mountain area, the requirement to brake block is more stringent than general road conditions.Firstly, being wanted under the road conditions of mountain area
Brake block is asked to have excellent heat resistance, if in the case where long and steep downgrade, the temperature of brake disc reaches 800 degree very sometimes
To higher.Current market sales of brake block is extremely difficult to this heatproof degree, during driver is in order to guarantee long and steep downgrade
Vehicle can be checked, often using cooling provisions such as water sprays, or walks one section and stop to carry out the cooling of brake system.Even if in this way
It is annual also innumerable because of accident caused by brake failure.Secondly, service life ratio of the existing brake block under the road conditions of mountain area is just
Service life under Chang Lukuang want it is short very much, or even what is had can only run thousands of kilometers, the product service life of even some genuine
Barely satisfactory, this causes very big rise with vehicle cost to car owner again.
Although various dazzling brake block currently on the market, but without exclusively for heavy-duty truck on mountain
The brake block for using and developing under area's road conditions.Therefore, how a kind of automobile-used disc brake pad friction material of heavy type and brake are provided
Piece preparation process is those skilled in the art's urgent problem to be solved.
