Abstract
A novel polyethylene material is disclosed. The novel polyethylene material is characterized by comprising following raw materials by weight: 55-65 parts of ethylene acrylic rubber GLS, 10-15 parts of acrylate rubber ER, 40-50 parts of nitrile butadiene rubber (NBR), 8-12 parts of high-wear-resistance carbon black, 5-7 parts of white carbon black, 3-4 parts of dioctyl meta-phthalate, 0.5-0.7 part of a vulcanizing agent used for AEM crude rubber, 1 part of an ether type plasticizer, 1-2 parts of an anti-ageing agent, 2 parts of an accelerator, 0.5-0.7 part of magnesium oxide and 0.4 part of coumatone, with the accelerator being a mixture of an accelerator CZ and an accelerator TMTD in a ratio of 2:1. Addition of the white carbon black improves adhesion force among rubber materials and improves tensile strength and tear strength of the rubber materials. An obtained product has good corrosion resistance and good ageing resistance, temperature resistance increases from original 150 DEG C to 170 DEG C, and oil resistance increases from original 130 DEG C to 150 DEG C. Good protection functions can be achieved when the product is used in a ventilation pipe. Comprehensive requirements of using performance of products can be met.
Description
Technical field
The invention belongs to sebific duct technical field, be specifically related to novel polyethylene material.
Background technology
Acrylic elastomer (hereinafter referred to as ACM) take acrylate as the elastomerics that main monomer obtains through copolymerization, and its main chain is saturated carbon chains, and side base is polar ester groups.Because its many excellence given by special construction, as heat-resisting, ageing-resistant, oil resistant, resistance to ozone, uvioresistant etc., mechanical property and processing characteristics are better than viton and silicon rubber, and it is heat-resisting, ageing resistance and oil-proofness are better than paracril.In the prior art, acrylic elastomer is used for product obtained in rubber layer, although through finding that it has sufficient physicals as oil-proofness, resistance to ozone, anti-weather-aging property, its high and low temperature resistance is not enough.
Paracril is obtained through emulsion polymerization by divinyl and vinyl cyanide, and paracril mainly adopts emulsion polymerization at low temperature to produce, and oil-proofness is fabulous, and wear resistance is higher, and thermotolerance is better, and bonding force is strong.Its shortcoming is that lower temperature resistance is poor, ozone resistance is poor, and electrical property is inferior, and elasticity is slightly low.Paracril is mainly for the manufacture of oil resisting rubber goods.
Summary of the invention
The object of the present invention is to provide novel polyethylene material, a kind of rubber compounding that can meet above FAM B oil standard, and the working method meeting recipe requirements is provided accordingly, be applied to the manufacture of vehicle crankcase ventilation sebific duct excellent and there is the product of abundant physical property (as resistance to ozone, anti-weather-aging property) to high-low temperature resistant, oil resistance.
The technical scheme that the present invention takes is:
Novel polyethylene material, is characterized in that, feed components is composed as follows according to weight part:
Ethylene-acrylate rubber GLS 55-65 part, acrylic elastomer ER 10-15 part, paracril NBR 40-50 part, high abrasion carbon black 8-12 part, White Carbon black 5-7 part, partially phthalic acid dioctyl ester 3-4 part, vulcanizing agent 0. 5-0.7 part of AEM rubber, 1 part, ethers softening agent, anti-aging agent 1-2 part, promotor 2 parts, described promotor are the mixture that accelerant CZ and Vulcanization accelerator TMTD form according to 2:1; Magnesium oxide 0.5-0.7 part, coumarone 0.4 part.
The invention has the beneficial effects as follows:
Add White Carbon black in the present invention and can improve bonding force between elastomeric material, and improve tensile strength and the tear strength of elastomeric material, the product obtained has well corrosion-resistant and ageing resistance, heatproof has brought up to 170 DEG C by original 150 DEG C, oil resistance has also brought up to 150 DEG C by original 130 DEG C, use it in vent-pipe and realize good protective effect, the composite request of the use properties of product can be met.
