    专利说明:

    used crankcase ventilation tube of acrylic rubber, but currently used, acrylic rubber is difficult to withstand the growing car crankcase temperature; While some advanced models with ethylene acrylate rubber, ETEN acrylate rubber oil poor performance of acrylic rubber, expensive and difficult to low-end cars in general use.
    Invention The object of the invention is to provide a superior resistance to oil currently used, vinyl and acrylic rubber, heat resistant properties of acrylate rubber and low cost of preparation of acrylate rubber raw materials.
    To achieve the above objectives, this invention provides an applied crankcase ventilation tube of acrylic rubber fertilizer recipe material characterized by quality as follows, acrylic rubber PA 402L, 40 ~ 70; of acrylic rubber PA 402 H, 30 ~ 60 and stearic acid, 1 ~ 2; application Dusantox 86, 2 ~ 3; Vanfre VAM, l ~ 2 processing additives, black N330, 25 ~ 45; N550, 10 ~ 30 black, potassium stearate, 0.2 ~ 0.5; sodium stearate, 1 ~ 4, and sulfur, 0.l ~ 0.3.
    Acrylic rubber (ACM) is acrylic alkyl ester (CH2 = CH-COOR) as the main unit and a small amount of Crosslinking copolymerization of monomers and active groups into a class of elastomers. According to their molecular structure of the Crosslinking monomer in different drying systems system is not the same when processing, acrylic rubber can be divided for containing chlorine polyamine crosslinked type, does not contain chlorine polyamine crosslinked type, self-Crosslinking, carboxylic acid acid ammonium nitrate salt SOAP special properties of brand type, cat. There are also special acrylic rubber, fluorine rubber and thermoplastic methacrylate ester.
    Acrylate rubber with good heat-resistant and oil-resistant performance, but does not mean that you can directly use, the appropriate choice of brands, as well as appropriate drying systems system and reinforcement of the research system is the achievement of part.
    This invention uses Japan NOK PA-402L, PA-402H Acrylate Rubber Corporation, common features in its molecular structure have two: one is high polar; others are completely saturated with, so they have superior resistance to mineral oils and high temperature oxidation resistance. Oil resistance for its second only to fl uor rubber, similar to NBR and high acrylonitrile content in general. Between it Heat resistance between general rubber and silicone rubber, nitrile rubber with a temperature of more than 30 ~ 60 ° C, maximum use at 180 ° C, recurring and used for a short time up to 200 ° C, 150 ° C long-term use without obvious changes .
    Most importantly, it also contains extreme pressure agents such as sulfur, chlorine, phosphorus extreme pressure lubricating oil is very stable, with temperatures up to 150 ° C, continuous use temperature higher. Acrylate rubber with excellent resistance to ozone, air tightness, resistance to deformation and crack growth resistance of bending and stretching and UV-resistant paint and so on, around the engine extended use at high temperature and little change in its performance. Second, due to differences in Moreno viscosity (PA-402L low Moreno, PA-402H Gao Menni), when both time, Moreno is good for machining, Gao Menni is good for performance, this ensures good processability both physical and mechanical properties .
    Composed of potassium, sodium stearate, curative stearic acid and sulfur SOAP system. Rhyme slowly with sodium stearate, process safety, potassium stearate scorch easily. Potassium, sodium stearate and stearic acid, change the scale and you can control the scorch time and not cure the state the effect is significant. Can increase the rate of curing and vulcanization sulfur levels. Through the reasonable ratio of these, three can guarantee the vulcanization of rubber processing speed and safety.
    Car crankcase ventilation tube extrusion pipe, and therefore requires extrusion of the rubber compound with good performance. This invention utilizes rapid extrusion black N5 50 guarantee plastic material extrusion properties, while high wear oven black N330 guarantee the strength of Vulcanized rubber.
