Embodiment 1

[0021] Example 1: Put 1 part (1 part is 50g, the same below) of γ-aminopropyltriethoxysilane in a flask, pour ethyl acetate in the ratio of 1:7 to the silane coupling agent, and then add For 1 part of p-toluenesulfonic acid, then add 7 parts of nanometer silicon dioxide powder and 3 parts of nanometer barium sulfate powder to the ethyl acetate solution of the coupling agent under stirring state, and treat it with ultrasonic vibration for 40 Minutes later, the ethyl acetate was distilled off under reduced pressure and dried to obtain the active nano filler; Mix with 20 parts of xylene, then add 15 parts of cycloaliphatic epoxy resin CER-170 (manufactured by Wuhan Senmao Fine Chemical Co., Ltd.) and active nano-filler, stir evenly, heat up to 110 ° C, and disperse at a constant temperature of 1000 rpm for 30 Minutes, to obtain mixed resin; Then 15 parts of butyl acetate, 8 parts of carbon black, 1.5 parts of cellulose acetate butyrate, 2 parts of octadecyl dimethyl hydroxyethyl ...

Embodiment 2

[0022] Example 2: 2 parts (1 part is 50g, the same below) γ-aminopropyltrimethoxysilane is placed in a flask, poured into ethyl acetate in a ratio of 1:7 with the silane coupling agent, and then add the 1.5 parts of p-toluenesulfonic acid, then add 5 parts of nano-silica powder and 2 parts of nano-barium sulfate powder to the ethyl acetate solution of coupling agent under stirring state, and treat with ultrasonic vibration for 40 minutes Finally, the ethyl acetate was distilled off under reduced pressure and dried to obtain active nanofillers; then in the reaction kettle of the vacuum disperser, first mix 90 parts of thermosetting hydroxyacrylic resin (A900) with 25 parts of xylene, and then add 18 parts of cycloaliphatic epoxy resin CER-170 and active nano-filler, stir evenly, heat up to 115 ° C, and disperse at a constant temperature of 1000 rpm for 30 minutes to obtain a mixed resin; then 24 parts of butyl acetate, 10 parts of carbon black , 2 parts of cellulose acetate but...

Embodiment 3

[0023] Example 3: 1.5 parts (1 part is 50g, the same below) of γ-aminopropyltriethoxysilane is placed in a flask, poured into ethyl acetate at a ratio of 1:7 to the silane coupling agent, and then added For 1.2 parts of p-toluenesulfonic acid, then add 6 parts of nano-silica powder and 2.5 parts of nano-barium sulfate powder to the ethyl acetate solution of the coupling agent under stirring, and treat it with ultrasonic vibration for 40 Minutes later, the ethyl acetate was distilled off under reduced pressure, dried to obtain the active nanofiller; then in the reactor of the vacuum disperser, 100 parts of thermosetting hydroxyacrylic resin (A900) was mixed with 30 parts of xylene, and then Add 20 parts of cycloaliphatic epoxy resin CER-170 and active nano filler, stir evenly, raise the temperature to 120°C, and disperse at a constant temperature of 1000rpm for 30 minutes to obtain a mixed resin; then add 20 parts of butyl acetate, 9 parts of carbon Black, 1.8 parts of cellulos...

Abstract

The invention relates to a shakeproof and wearproof paint for a damping silencing plate, which is mixed with amino resin according to the proportion of between 1 to between 0.25 and 0.3 in use; the shakeproof and wearproof paint mainly consists of the following compositions in portion by weight: 82 to 100 portions of thermosetting hydroxy acrylic resin, 15 to 20 portions of alicyclic epoxy resin, 8 to 10 portions of hydrocarbon black, 5 to 7 portions of nanometer silicon dioxide, 2 to 3 portions of nanometer permanent white, 1 to 2 portions of amino silane coupling agent, 1 to 1.5 portions of p-toluene sulfonic acid, 1.5 to 2 portions of cellulose acetate butyrate, 1.5 to 2.5 portions of octadecyl dimethyl hydroxyethyl quaternary ammonium nitrate, 15 to 24 portions of butyl acetate and 20 to 30 portions of xylene. The shakeproof and wearproof paint has the characteristics of good constructing, levelling and decorating performances; and a paint film of the damping plate using the shakeproof and wearproof paint has good anticorrosive performance and prominent manifestations in wearing resistance, flexility, adhesive force and other mechanical performances.

Description

technical field [0001] The invention relates to a paint for auto parts, in particular to a shock-resistant and wear-resistant paint for shock-absorbing and sound-absorbing sheets. Background technique [0002] The shock-absorbing and noise-absorbing pad is an important part of the brake pad. When the brake pad is braking, the shock-absorbing and noise-absorbing pad can damp the vibration and noise caused by the friction block in the brake pad. At present, in the painting of the appearance of the shock absorber, most of them still use ordinary paints, such as enamel paints, acrylic resin paints, etc., as spraying materials. In the extreme working environment of frequent braking of brake pads, the shortcomings of these paints such as low adhesion, poor wear resistance, impact resistance, and easy aging are gradually exposed, which has a negative impact on the stable operation of automobile brake pads. Contents of the invention [0003] The invention mainly solves the techni...
