Technical field
The present invention relates to the automotive hose technical field, particularly a kind of high-performance ethylene-propylene-diene monomer sebific duct composition and preparation method.
Background technology
Along with the development of automotive hose technology, traditional automobile satisfies its service requirements with the product structure with casing ply usually with the cooling system sebific duct, and the test pressure and the pulse number that require mainly due to this type sebific duct are higher, and specific requirement sees the following form:
According to the requirement in the table, product is without breakage after the pulse test.But because cut-throat competition of the same trade, cause only when comprehensive cost is lower than other producer, just can better win the market, and the said products wants to reach this kind effect, can only under the prerequisite that original performance does not reduce, consider to remove original casing ply, the production technique of product is simplified, production efficiency improves, thereby reaches the effect that reduces comprehensive cost.
In view of the pulse testing requirement of this type of sebific duct 180,000 times, can only use properties of rubber in control and set about, making it reach high rigidity and height, to pull apart brute force be hardness requirement 60 ~ 80A, pulls apart powerful requirement 〉=10Mpa, also will satisfy manufacturing technique requirent simultaneously.
In addition, for this type of sebific duct owing to being that the existing product that substitutes uses under hot environment, so also be that higher requirement is arranged on the condition of hot air aging, the hot air aging condition is 150 ℃ of 504h, and the decay of pulling apart elongation after the hot air aging require into＜-30%, so prior art be difficult to satisfy so exacting terms.
