The invention discloses an antifouling material for an automobile fender lining and a preparation method of the antifouling material. The antifouling material for the automobile fender lining comprises the following raw materials according to weight percentage: 55-60% of synthetic emulsions, 10-15% of aqueous polyurethane emulsions, 2-5% of polytetrafluoroethylene emulsion, 3-8% of polysiloxane emulsion, 0.5-1% of coupling agent, 0.5-1% of a wetting agent, 0.1-0.2% of an antifoaming agent, 2-3% of a coalescing agent, 0.1-0.2% of a pH regulator, 1-2% of an antifreezing agent, 0.2-0.3% of a preservative, 1-2.5% of a thickening agent, 0.05-0.1% of essence and the balance of deionized water. The antifouling material for the automobile fender lining has the advantages that the surface energy islower, the surface energy of the automobile fender lining can be rapidly reduced after the material is coated on the automobile fender, a super-hydrophobic coating is formed on the automobile fenderlining, the hydrophobic angle can reach 116 degrees, the hydrophobic and oleophobic effects are achieved, the risk that metal parts are corroded and aged can also be reduced, plastic and the metal parts of an automobile are well protected, and the service life of the automobile fender lining is greatly prolonged.
本发明公开了一种汽车翼子板内衬防污材料及其制备方法。该汽车翼子板内衬防污材料,按重量百分比计,包括如下原料:合成乳液55~60%、水性聚氨酯乳液10~15%、聚四氟乙烯乳液2~5%、聚硅氧烷乳液3~8%、偶联剂0.5~1%、润湿剂0.5~1%、消泡剂0.1~0.2%、成膜助剂2~3%、PH调节剂0.1~0.2%、防冻剂1~2%、防腐剂0.2~0.3%、增稠剂1~2.5%、香精0.05~0.1%、去离子水余量。本发明提供的汽车翼子板内衬防污泥材料的表面能较低,涂装到汽车翼子板上面后,会迅速降低其表面能,在汽车翼子板内衬上形成一层超疏水涂层,疏水角可达到116°,起到疏水疏油的作用,也可以减少金属部件受到腐蚀和老化的风险,使汽车的塑料和金属部件得到很好的保护,大大提高汽车翼子板内衬的使用寿命。
