It is 3 hours dry under the conditions of 260~270 DEG C of temperature after boron phosphoric acid solution.
After the processing of boron oxide phosphoric acid solution, oxidation resistant ability gets a promotion luffa at high temperature, effectively extends silk
The service life of melon network and integral stop liner.
According to a kind of drum brake lining of the specific embodiment of the invention, the mass concentration of the phosphoric acid solution is 60~
70%.
According to a kind of drum brake lining of the specific embodiment of the invention, by the luffa in 60~80 DEG C of items of temperature
Under part, supersaturated boron oxide phosphoric acid solution is impregnated, soaking time is 3~4h.
According to a kind of drum brake lining of the specific embodiment of the invention, lateral surface (this of the drum brake lining
Invent the contact surface that institute's facies digitales laterales manus is brake lining and brake hub) it is equipped with a S-shaped slag guiding trough, the width of the slag guiding trough
Degree is less than 2mm, and the depth of the slag guiding trough is less than 2mm；Luffa is filled in the slag guiding trough.
A slag guiding trough is opened up on the lateral surface of brake lining and hub contacts, slag guiding trough is narrow for one in brake lining
, by the natural reticular texture of luffa, a small amount of dust of generation is attracted deposit in slag guiding trough wherein filling luffa in narrow gap
It is interior, to further play the role of stable friction coefficient, reduce abrasion.
Slag guiding trough is not only able to attracting dust, and when braking disc spins, and under the influence of centrifugal force, brake disc generates
Hot gas can quickly shed along slag guiding trough, to improving braking ability to a certain extent.
Beneficial effects of the present invention are：
1. adding this native cellulose of luffa in the present invention, the small-molecule substances such as carbon black can be effectively adsorbed, are reduced
The discharge of oil soluble material, and then weaken the degree for falling ash adherency.
2. adding brass borings metal anti-friction agent in the present invention, main function is demagnetization, reduces brake lining and brake hub
Magnetic absorption (previous experiments show drum brake be used for a long time after remain under dust main component be iron oxide and four
Fe 3 O, and these residues are easy to that magnetic absorption occurs with brake hub, it is not easy to it is discharged).Stabilization is may also function as to rub
It wipes coefficient, wear small effect.For in braking process, the small amounts iron and ferroso-ferric oxide of generation, the present invention is to silk
Melon network has carried out modification, can effectively be adsorbed to it.
