US07275574B2 Thermoplastic elastomer composition and process for producing the same and pneumatic tire and hose using the same 有权
热塑性弹性体组合物及其制造方法及使用其的充气轮胎和软管

Thermoplastic elastomer composition and process for producing the same and pneumatic tire and hose using the same
Abstract:
Thermoplastic elastomer composition dynamically vulcanized with a 50 to 95% gelation rate has superior heat resistance, durability, and air permeation prevention, is flexible and usable as a pneumatic tire air permeation preventive layer. A composition having reduced domain rubber particle size is produced from a high rubber ratio material by mixing composition (C) under melt viscosities ratio of rubber composition (A)/resin (B) of 0.8 to 1.2 and formula (φA/φB)×(ηB/ηA)
Abstract(Chinese):

以50〜95％凝胶化速度动态硫化的热塑性弹性体组合物具有优异的耐热性，耐久性和防透气性，是柔性的，可用作充气轮胎防气层。 通过在橡胶组合物（A）/树脂（B）的熔融粘度比为0.8〜1.2和式（phi A）之间混合组合物（C），由高橡胶比材料制造具有减小的畴橡胶粒径的组合物， /SUB>/phiB)x(etaB/etaA)1.0在橡胶组合物（D）/组合物的熔体粘度比下 （C）为0.8至1.2和式（i> i i i SUB SUB SUB SUB SUB SUB SUB SUB SUB SUB SUB SUB SUB SUB SUB SUB SUB SUB SUB >）<1.0，其中phiA，i i i i i i>>>>>>>>>>>>>>>>>>>>>> rubber rubber rubber 组合物（A）和树脂（B），组合物（C）和橡胶组合物（D）分别为乙烯，乙烯和/ >和η'分别是橡胶组合物（A），树脂（B），组合物（C）和橡胶组合物（D）的熔体粘度。 热塑性弹性体组合物可以具有弹性体组合物（A）分散相和热塑性树脂组合物（B）基质。
