Multi-functional memory back-up mirror material

Abstract

The invention discloses a multi-functional memory back-up mirror material. A mirror shell is prepared by using natural rubber and butadiene rubber as main materials, and a lens is made of stainless steel. The material of a back-up mirror shell is high in strength and elasticity, the back-up mirror shell is prepared from the raw materials by mass ratio: 60 parts of natural rubber, 40 parts of butadiene rubber and 50.5 parts of a compounding agent. The compounding agent is prepared from the main components: carbon black, montmorillonite, sulfur, stearic acid, calcium bicarbonate, a silane coupling agent KH550, an anti-aging agent D and an antioxidant, wherein the mass ratio of carbon black to montmorillonite to sulfur to stearic acid to calcium bicarbonate to silane coupling agent KH550 to anti-aging agent D to antioxidant is 10 to 20 to 10 to 2.5 to 1 to 1.5 to 5 to 0.5. The tensile strength of the material of the back-up mirror shell is as low as 20.9 mpa, the wear resistance is as high as 0.11 cm<3> / 1.61 km, and the resilience is as high as 94%. The elasticity and strength of the multi-functional memory back-up mirror material after the installation of the stainless steel lens material are in accordance with the use, the installed stainless steel lens has anti-collision performance and the lens is not stained with water in rainy days, and the practicability is high.

Description

technical field [0001] The invention relates to a multi-functional memory type reversing mirror material. Background technique [0002] The rear view mirror is the second pair of eyes of the driver during the driving of the car. It plays a vital role for motorists, because it can improve people's safety when driving a motor vehicle, and is widely used by people. With the development of science and technology and the improvement of people's living standards, the number of cars is also increasing year by year, which makes the driving and parking space of cars smaller and smaller, so the reversing mirror will inevitably be scratched. In addition, when the car is driving in rainy days, the rear view mirror will become blurred with rain, which will affect the clarity of vision and reduce driving safety. In order to solve this problem, various rear view mirrors have begun to appear. Most of the rear view mirrors on the domestic and foreign markets are structurally adjusted. Alth...
