Waterproof and oil-proof coating for automobile

The invention belongs to the technical field of automobile protection, and particularly relates to a waterproof and oil-proof coating for an automobile. The mass formula of the coating comprises: 15-20 parts of polypropylene resin, 3-6 parts of a dispersant, 15-20 parts of polyethylene glycol oleate, 8-12 parts of silica, 2-4 parts of a stabilizer, 10-12 parts of a filler, 3-6 parts of a couplingagent and 3-5 parts of an ultraviolet protective agent. The invention has good oil-proof and water-proof effects, and utilizes the non-hydrophilic and non-lipophilic properties of polyethylene glycololeate to prevent attachment of oil stains and water droplets and improve the anti-fouling performance. 本发明属于汽车防护技术领域，具体涉及种汽车的防水防油涂层，所述涂层的质量配方如下：聚丙烯树脂15-20份、分散剂3-6份、聚乙二醇油酸酯15-20份、二氧化硅8-12份、稳定剂2-4份、填料10-12份、偶联剂3-6份、紫外防护剂3-5份。本发明具有良好的防油防水效果，利用聚乙二醇油酸酯的不亲水不亲油性能，防止油污与水珠的附着，提升了防污性能。
