Directly and glass contact, this scraping article of will praying for rain has good toughness, shape stability and corrosion resistance to bar, because of
The production of this windscreen wiper bar is of crucial importance.Existing windscreen wiper bar major part is made up of rubber, toughness, shape stability and
Corrosion resistance is poor, and particularly pliability is poor so that windscreen wiper bar is inadequate with the laminating degree of glass, causes
Cannot be clean by glass scraper, affect the visual field of the driver, bring potential safety hazard, it is impossible to meet the demand in market.
The service life of existing wiper rubber bar is shorter, mainly relevant with sun direct projection, especially with rain erosion
Being being exposed to the sun of the sun in summer, ultraviolet is relatively strong, owing to ultra-violet bands is easily absorbed (ultraviolet one by rubber
The energy (E=h ν) of photon is close with carbon carbon covalency), promote rubber carbon-carbon bond accelerated ageing to rupture, show
Carrying out surface checking, product strength reduces, hardness enhancing etc., and then causes wiper rubber bar to use.
Summary of the invention
The technical problem to be solved is to provide high tenacity wiper silica gel strip and manufacturer thereof
Method, the silica gel strip good toughness manufactured, corrosion resistance is strong, and pliability is good, it is possible to effectively by glass scraper
Totally, and being difficult to aging, service life is long.
For solving above-mentioned existing technical problem, the present invention uses following scheme: high tenacity wiper silica gel
