Brake surface coating, application of brake surface coating, carbon-ceramic brake disc and preparation method of carbon-ceramic brake disc
The invention belongs to the technical field of preparation of carbon-ceramic brake discs, and particularly relates to a brake surface coating and application thereof, a carbon-ceramic brake disc and a preparation method of the carbon-ceramic brake disc. The brake surface coating comprises 75-80% of silicon carbide, 10-15% of first liquid phenolic resin and 10-15% of pre-impregnated chopped carbon fibers, the pre-impregnated chopped carbon fiber yarns are obtained by soaking carbon fiber yarns in a resin impregnation liquid and then carrying out thermocuring; the solid content of the first liquid phenolic resin is 60-65%; and the length of the pre-impregnated short carbon fiber yarn is less than or equal to 10mm. The brake surface coating provided by the invention is used for preparing the carbon-ceramic brake disc, so that on the basis that the bonding force between a surface brake coating and a disc body is greatly enhanced and the coating is not easy to fall off, the abrasion resistance of the surface of the coating is prevented from being reduced and the brake effect is prevented from being influenced, and the obtained carbon-ceramic brake disc is high in strength, good in brake stability and long in service life.
本发明属于碳陶制动盘制备技术领域，具体涉及一种制动面涂料及其应用、一种碳陶刹车盘及其制备方法。本发明的制动面涂料包括：碳化硅75～80％，第一液态酚醛树脂10～15％，预浸短切碳纤维丝10～15％；所述预浸短切碳纤维丝由碳纤维丝经树脂浸渍液浸泡后热固化得到；所述第一液态酚醛树脂的固含量为60～65％；所述预浸短切碳纤维丝的长度≤10mm。本发明提供的制动面涂料用于制备碳陶刹车盘，使表面刹车涂层与盘体的粘接力大大增强，涂层不易脱落的基础上，避免涂层表面的耐磨性变小，影响制动效果，得到的碳陶刹车盘的强度高，制动稳定性好，使用寿命长。
