Acrylate rubber turbine ascending pipe and preparation method thereof

Abstract

The invention relates to a turbine ascending pipe and a processing method thereof. The raw material comprises acrylate rubber, stearic acid, fast extruding carbon black N550, dibutyl adipate plasticizer, complexing organic alkyl acid internal release agent, antiager 4,4-double diphenylamine, vulcanizing agent hexamethylene diamine formate and accelerator melaniline. In parts by weight specified by a rubber formula, all rubber and corresponding auxiliary materials are burdened, a banbury mixer two-step rubber mixing technology is adopted for production to ensure that the appearance of glue stock is light after mixed, and the glue stock is evenly mixed. A production method of integrating inner rubber extrusion, weaving and outer rubber extrusion is adopted so that the production technology is simplified, cost is saved and operation is more convenient. The turbine ascending pipe obtains the optimal material performance combination, satisfies the comprehensive requirement of the use performance, the production cost and the like of the product, and satisfies the required use temperature of 180 DEG C-220 DEG C; and meanwhile, the rubber layer and aramid line have the characteristic of high bonding strength and the product is better in pulse performance.

Description

technical field [0001] The invention relates to the technical field of rubber hoses, in particular to an acrylic rubber turbocharger hose with medium and high temperature resistance and a preparation method thereof. Background technique [0002] With the improvement of people's living standards and the development of the automobile industry, more and more automobiles have entered people's lives, and the requirements for the connecting hoses of automobile intercoolers and turbochargers are also getting higher and higher. It is a material with high and low temperature resistance, weather resistance, excellent oil resistance and environmental protection requirements. This is mainly because the oil and alcohol combustion gas in the medium used by the automobile engine and the environment enters the entire engine system, resulting in instantaneous temperature of the environment and medium. The highest temperature can reach 230℃~250℃. An ethylene acrylate rubber turbo hose has be...

AI Technical Summary

Problems solved by technology

An ethylene acrylate rubber turbo hose has been disclosed in ZL200710057723.5, but the turbo hose of this structure is only suitable for models with a high temperature of 175°C. Another one is also disclosed in ZL200710057722.0 A turbocharger hose with fluororubber inner rubber and silicone rubber outer rubber. The hose with this structure has the best high temperature resistance and oil resistance performance. It can reach a high temperature of 250 ° C. It can be used in any environment. The cost of the hose of this structure is very high

The problem we are facing is how to choose the connecting hose for the intercooler and supercharger environment and the temperature of the medium at 180°C to 200°C
