Abstract

The invention discloses an NBR-PVC (nitrile butadiene rubber-polyvinyl chloride) blended rubber-plastic alloy material, a preparation method and an application. The NBR-PVC blended rubber-plastic alloy material is prepared from raw materials in parts by weight as follows: 75-80 parts of NBR, 20-25 parts of PVC paste resin, 4-10 parts of an activator A, 0.5-2.5 parts of an activator B, 1-5 parts ofa heat stabilizer, 1-3 parts of an anti-ageing agent RD, 3-6.5 parts of protective wax, 85-105 parts of carbon black, 30-40 parts of a plasticizer, 0.3-0.8 parts of a vulcanizing agent A, 0.5-1.2 parts of a vulcanizing agent B, 0.9-1.5 parts of an accelerator A and 1.5-2.5 parts of an accelerator B. The preparation method is simple, lower in cost and suitable for industrial production; the obtained product has excellent comprehensive performance and wide working temperature range, is resistant to fuel, lubricating oil and ozone and good in mixing dispersity and can be widely applied to materials of gas inlet hoses of engines.

Description

technical field [0001] The invention specifically relates to an NBR-PVC blended rubber-plastic alloy material, a preparation method and an application thereof. Background technique [0002] The car engine intake hose is connected between the air filter and the intake manifold. Its material performance indicators generally include high and low temperature resistance (-40~100°C), fuel resistance (such as gasoline, diesel, biofuel), lubricating oil resistance (such as engine oil, gear oil) and ozone resistance. At present, although the existing hydrogenated nitrile rubber mixtures and special brands of low-temperature-resistant ternary fluorine rubber can all meet the index requirements of automobile engine intake pipe materials, the price is very high. For example, the market price of hydrogenated nitrile rubber raw rubber is about 200 yuan / kg, and the market price of low-temperature ternary fluorine rubber is about 230 yuan / kg, so the two are rarely used in middle and low-en...
