[0003] At present, CM materials are mainly used in automobile rubber hoses. Although CM materials have some characteristics of rubber and some properties of plastics, and can meet various design requirements, the application of CM in automobile rubber hoses is still limited to some ozone-resistant and resistant In thermal hoses, it can be seen that the application range of polymer materials in automotive hoses is relatively narrow and needs to be further expanded

Embodiment 1
[0023] Raise the temperature of the open mill to 70°C, adjust the roller distance to the minimum, add chlorinated polyethylene CPE and masticate until there are no particles, and the mastication will be uniform; then wrap the evenly masticated CPE on the open mill (roller temperature 50 ℃), followed by adding magnesium oxide, barium stearate, carbon black (grade N330), silicon powder, plasticizer (dioctyl phthalate DOP), antioxidant RD, nitrile rubber NBR (grade 1052) , vulcanizing agent TCY, and cross-linking agent TAIC-70 were mixed evenly (at 170°C for 20 minutes), and the film was released; finally, the rubber was parked for 24 hours and then re-milled to form the automobile vent hose A1; among them, CPE, NBR , carbon black, silicon powder, plasticizer, magnesium oxide, anti-aging agent, barium stearate, vulcanizing agent, cross-linking agent in a weight ratio of 70:30:35:55:25:10:1:3:3 :6.
Embodiment 2
[0025] According to the method described in Example 1, the automobile breather rubber hose A2 is obtained, the difference is that CPE, NBR, carbon black, silicon powder, plasticizer, magnesium oxide, anti-aging agent, barium stearate, vulcanizing agent, crosslinking aid The weight ratio of the agent is 70:28:33:53:23:8:0.8:2.8:2.8:5.
Embodiment 3
[0027] According to the method described in Example 1, the automobile breather rubber hose A3 is obtained, the difference is that CPE, NBR, carbon black, silicon powder, plasticizer, magnesium oxide, anti-aging agent, barium stearate, vulcanizing agent, crosslinking aid The weight ratio of the agent is 70:32:37:57:27:12:1.2:3.2:3.2:6.

Abstract
The invention discloses a chlorinated polyethylene / butadiene-acrylonitrile rubber compound rubber material and a preparation method thereof. The chlorinated polyethylene / butadiene-acrylonitrile rubbercompound rubber material consists of the following components: chlorinated polyethylene CPE, butadiene-acrylonitrile rubber NBR, carbon black, silicon powder, a plasticizer, magnesium oxide, an anti-aging agent, barium stearate, a vulcanizing agent and an assistant crosslinker, wherein the weight ratio of CPE to NBR to carbon black to the silicon powder to the plasticizer to magnesium oxide to the anti-aging agent to barium stearate to the vulcanizing agent to the assistant crosslinker is 70:(25-35):(30-40):(50-60):(20-30):(5-15):(0.5-1.5):(2-4):(2-4):(3-8). The chlorinated polyethylene / butadiene-acrylonitrile rubber compound rubber material can be used as a raw material of an automobile rubber tube, and at the same time, the prepared automobile rubber tube has excellent mechanical properties, oil resistance and aging resistance. Meanwhile, the preparation method is simple in process and easy to operate.
Description
technical field [0001] The invention relates to polymer materials, in particular to a chlorinated polyethylene / acrylonitrile-butadiene rubber compound rubber material and a preparation method thereof. Background technique [0002] Chlorinated polyethylene is a saturated polymer material, white powder in appearance, non-toxic and tasteless, has excellent weather resistance, ozone resistance, chemical resistance and aging resistance, and has good oil resistance, flame retardancy and coloring performance. Good toughness (still flexible at -30°C), good compatibility with other polymer materials, and high decomposition temperature. Chlorinated polyethylene resin is a new type of synthetic material with a series of excellent properties. It is an excellent impact modifier for PVC plastics and a synthetic rubber with good comprehensive properties. It has a very wide range of applications and has been widely used in cables, wires, hoses, tapes, rubber and plastic products, sealing m...
