The present invention relates to plastic film fields, disclose a kind of high-wearing feature composite plastic pad pasting and preparation method for automobile.Including following preparation process：（1）Heating, which is reacted, after calcium sulfate crystal whiskers are mixed with ferroso-ferric oxide precursor liquid is made magnetic fento dispersion liquid；（2）To lotion is made after polytetrafluoroethylene (PTFE) hydrophobically modified, magnetic fento dispersion liquid casting film-forming is added, modified Teflon film is made after dry solidification, the parts by weight of each component are：6 ~ 10 parts of polytetrafluoroethylene (PTFE), 0.5 ~ 1 part of polysilazane, 0.5 ~ 1 part of emulsifier, 35 ~ 40 parts of water, magnetic 48 ~ 58 parts of fento dispersion liquid；（3）Modified Teflon film is subjected to the be bonded compound high-wearing feature composite plastic pad pasting to get for automobile with rupture pressure disc, thermal isolation film.For automotive compounded pad pasting produced by the present invention compared with general-utility car pad pasting, abrasion resistance properties are good, and film strength is high, and durability is good, and service life is long, have extremely wide application prospect. |
