Abstract

The invention belongs to the field of new materials, and provides graphene composite rubber for a durable automobile wiper blade and a preparation method for the graphene composite rubber. The methodcomprises the following steps that p-aminosalicylic acid is added into a phosphate buffer solution, graphene oxide and a AlCl3 catalyst are added, ultrasonic treatment is carried out for 4 hours, heating is carried out to reach 60 DEG C, then an ascorbic acid reducing agent is added, ultrasonic treatment is carried out on low-molecular epoxy resin liquid for 30 minutes, cooling is carried out to reach room temperature so as to obtain a functionalized graphene / low molecular epoxy resin mixed solution, natural rubber (NR) is put into an open mill, and stearic acid, the prepared functionalized graphene / low molecular epoxy resin mixed solution, molybdenum disulfide, aromatic hydrocarbon oil, an accelerant TMTD and a cross-linking agent DCP and rest auxiliary agents are sequentially added, areuniformly mixed and then are taken out so as to obtain the graphene composite rubber.

Description

technical field [0001] The invention belongs to the field of new materials, and in particular relates to a graphene composite rubber for durable automobile wiper blades and a preparation method thereof. Background technique [0002] The front windshield wiper system of a car is an important part of the car, also known as the wiper, which is used to clean the rain, dust, snow, etc. sex and security. [0003] During the wiping process of the wiper, the wiper blade is in direct contact with the glass, which can keep the outer surface of the windshield clean. It is an indispensable part of the car. It must have heat resistance, cold resistance, acid and alkali resistance, corrosion resistance, performance It fits the windshield, reduces the load on the motor, low noise, strong water repellency, soft and can not scratch the windshield, etc. Since the wiper blades are wiped for a certain period of time, the rubber strips of the skeleton wiper blades will be worn out, so they nee...
