Abstract

The invention discloses a pressurizing pipe with high-temperature resistance and a preparation process thereof. The pressurizing pipe is prepared from the following raw materials in parts by weight: methyl vinyl silicone rubber, fluororubber premixed rubber, butadiene styrene rubber, hydroxyl silicone oil, nano silicon powder, polymetallic organosiloxane, zinc oxide, vapor white carbon black and the like. The heat-resistant agent is prepared from the polyorganometallic siloxane, the zinc oxide, the vapor white carbon black, the tris(trimethylsilyl)phosphate, an aromatic acid zine salt and mercaptobenzothiazole, and by reasonable combination of the polyorganometallic siloxane and the tris(trimethylsilyl)phosphate, good dispersity of the components and compatibility of the rubber are utilized to improve the activity utilization rate of zine oxide and vapor white carbon black; and mercaptobenzothiazole is used for promoting more polysulfide cross-linking bonds of the rubber, so that the endogenous heat in the processing process of the rubber material can be effectively reduced, the stability of the polysulfide cross-linking bonds is improved, the cross-linking density of vulcanized rubber is kept, and the heat resistance of the rubber is greatly improved.

Description

technical field [0001] The invention relates to the technical field of booster tubes, in particular to a booster tube with high temperature resistance and a preparation process thereof. Background technique [0002] In recent years, due to the rapid growth of China's huge automobile market, under the pressure of energy crisis and environmental protection, the rapid development of contemporary automobile engine electronics technology and turbocharger technology interacts with the development of turbocharger manufacturing technology, which promotes The rapid development of the turbocharger industry. At the same time, with the improvement of turbocharger efficiency and the development of matching technology, turbocharger technology has been widely used in the automotive industry. Based on the widespread application of turbochargers in automobiles, turbocharger tubes for turbochargers have also developed rapidly. The type of turbocharger hose varies with the operating temperat...
