Problems solved by technology

[0003] At present, the wiper rubber strips on the market have the following problems: if the rainfall is too large, the amount of rain in one wipe will be too small, causing frequent swings of the wiper rubber strips, which will easily affect the driver's vision and may cause traffic accidents; Exposed to the outside, the wiper strips are exposed to the wind and the sun, and are exposed to extreme complex conditions such as large temperature differences and ultraviolet rays. It is easy to cause premature damage to the wiper, and the service life is short. It needs to be replaced frequently, which increases the maintenance cost of the car; in a quiet car cabin , the noise generated by the rubber strip of the wiper and the window glass is also a problem that affects the comfort of the occupants
The wiper film manufactured by using the preparation material and preparation method of the wiper film of the present invention has been greatly improved in terms of service life and wiping effect, but it does not take into account that the amount of water wiped at one time is too small to cause frequent swings of the wiper. Affect the driver's vision, poor weather resistance

Abstract

The invention discloses a wiper rubber strip. The wiper rubber strip is prepared from the following raw material components: natural rubber, neoprene, an activator, polyacrylate resin, triallyl isocyanurate, an accelerator, carbon black, a processing aid, sulfur and an antioxidant, wherein the ratio of the natural rubber to the neoprene is 60: 40 to 70: 30. The wiper rubber strip prepared by adopting the preparation method of the wiper rubber strip has the advantages of good weather resistance, long service life and good wiping effect.

Description

technical field [0001] The invention relates to the field of wipers, in particular to a wiper rubber strip and a preparation method thereof. Background technique [0002] Car wiper, also known as car wiper, as one of the important safety components on the car, is used to remove foreign matter such as rain, snow, frost, fog, etc. a part of. The number of traffic accidents and the number of deaths each year in my country account for about 70% and 80% of the total number of accidents in the country respectively, ranking second in the world. In 2016 alone, road traffic accidents in my country caused 63,093 deaths and direct economic losses of 1.21 billion yuan . A large part of these traffic accidents is due to foreign objects such as windshield rain and snow not being wiped clean, causing the driver's line of sight to be blocked. The wiper rubber strip is an important part of the wiper to effectively remove foreign matter such as rain and snow on the surface of the car windsh...
