Material and the solvent of 15 parts by weight configure；Described is the green glue of powder with high-temperature resistant from glue, and the binder is
With high temperature tolerance can with various organic and inorganic filler can be compatible water soluble phenol resin, described fills out
Material is made of the barite and Frication powder of high rigidity, powdery white aluminium oxide resistant to high temperature and increase coating intensity and durability；
The solvent is alcohol.
Preferably, the parts by weight of white alumina described in the filler are 10, the parts by weight of the barite are
60, the parts by weight of the Frication powder are 5.
Preferably, the unburned bright coating be uniformly applied to brake-pad friction block with a thickness of 0.5~1.5mm,
The length of the unburned bright coating material is equal to the length of brake-pad friction block.
The unburned bright coating for being coated in brake-pad friction block surface includes the following production stages:
The first step pours into the components in certain proportion of coating in one bucket, drives stirring rod with high speed electric drill, at the uniform velocity stirs 30
~35 minutes, keep its each ingredient branch uniformly abundant, to obtain unburned bright coating；
Unburned bright coating is uniformly applied to by certain shape and specific thickness and length with silk screen plate and is rubbed by second step
Cleaning block surface；
The friction block coated is placed on interior by third step, and naturally dry 12 hours；
The friction block for having dried 12 hours is put into baking oven and is dried 30 minutes with 210 DEG C, product is made by the 4th step.
Following table is that unburned bright coating passes through the test data on constant speed tester for friction between
The calculation formula of coefficient of friction in the present invention, according to National Standard of the People's Republic of China, " brake for cars is served as a contrast
Piece GB5673-2008 " are as follows:
μ=f/F
