Formula of butyronitrile rubber/polyvinyl chloride co-mixed rubber ethanol resistance gasoline rubber pipe

Abstract

The invention relates to a formula of butyronitrile rubber/polyvinyl chloride co-mixed rubber ethanol resistant gasoline rubber pipe, comprising the following components in parts by weight: 30-70 parts of butyronitrile rubber, 70-30 parts of polyvinyl chloride, 3-10 parts of zinc oxide, 1-2 parts of anti-aging agent RD, 2-4 parts of dibasic lead phosphate, 1-3 parts of stearic acid, 2-4 parts of coumarone-indene resin, 10-40 parts of dioctyl phthalate, 20-50 parts of fast extruding furnace black (N550), 20-40 parts of figuline and 1.5-2.5 parts of an accelerating agent CZ. Through the performance contrastive analysis of the formula of butyronitrile rubber/polyvinyl chloride co-mixed rubber and the formula of the butyronitrile rubber, the comprehensive performance of the formula of butyronitrile rubber/polyvinyl chloride co-mixed rubber is better with low cost, which can satisfy the requirements of the traditional ethanol resistant gasoline.

Description

technical field [0001] The invention relates to the technical field of rubber formulations, in particular to a formulation of a nitrile rubber / polyvinyl chloride (NBR / PVC) blend rubber resistant to ethanol gasoline rubber hose. Background technique [0002] With the deepening of people's understanding of the global energy crisis and environmental protection, the fuel gasoline used in automobiles is gradually replaced by ethanol. It does not affect the driving performance of the car, and can effectively improve the performance and quality of oil products, and at the same time reduce the emission of major pollutants such as carbon monoxide and hydrocarbons (after adding 10% fuel ethanol to gasoline, the carbon monoxide emission in automobile exhaust can be reduced. decrease by more than 30%, and the emission of hydrocarbons by more than 10%). As a new type of clean fuel, ethanol gasoline is currently the development focus of renewable energy http: / / baike.baidu.com / view / 9292.h...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a formula of ethanol-resistant gasoline rubber hose, to solve the shortcoming of the hose's poor resistance to ethanol gasoline, it is proposed to use nitrile rubber / polyvinyl chloride (NBR / PVC) as the main material through formula design to meet the current product requirements. requirements for use
