Problems solved by technology

In the past, the protection of these important parts was very simple, such as covering them with ordinary fabric cloth or plastic film. Simple protection caused splashing water, humidity, automobile oil, road debris, dust, etc. to affect vehicle parts and reduce the cost of vehicle parts. The performance of the vehicle, thus affecting the quality performance and safety performance of the vehicle, the rapid drop in temperature will cause the internal pressure of some component assemblies to drop, forming a negative pressure, thereby inhaling pollutants, increasing fogging and possibly causing failure of parts, connectors, air pressure Sensors, electronic components, etc. are oxidized and rusted after being infiltrated by rainwater, gradually lose their functions, and frequent failures increase the unsafety and maintenance costs of the car

Abstract

The invention belongs to the technical field of automobile protection, and in particular relates to a waterproof and oil-repellent coating for automobiles. The quality formula of the coating is as follows: 15-20 parts of polypropylene resin, 3-6 parts of dispersant, polyethylene glycol oleic acid 15-20 parts of ester, 8-12 parts of silica, 2-4 parts of stabilizer, 10-12 parts of filler, 3-6 parts of coupling agent, 3-5 parts of UV protection agent. The invention has good oil-proof and water-proof effects, utilizes the non-hydrophilic and non-lipophilic properties of polyethylene glycol oleate, prevents the attachment of oil stains and water drops, and improves the anti-fouling performance.

Description

technical field [0001] The invention belongs to the technical field of automobile protection, and in particular relates to a waterproof and oil-repellent coating for automobiles. Background technique [0002] With the popularity of automobiles, people have higher and higher requirements for the quality and performance of automobiles. When automobiles are running in rain or high and low temperature weather, many important parts of automobiles are subject to pollution from rainwater, automobile oil, dust and other dirt. Such as lights, connectors, air pressure sensors, electronic components, and under the hood are constantly exposed to various weather, road conditions, and environments that may affect the driving performance of the vehicle. In the past, the protection of these important parts was very simple, such as covering them with ordinary fabric cloth or plastic film. Simple protection caused splashing water, humidity, automobile oil, road debris, dust, etc. to affect ve...
