Embodiment 1
[0027] According to the following parts by mass: CM: 50 parts, CPE: 50 parts, rare earth stabilizer: 6 parts, active MgO: 10 parts, epoxy soybean oil: 10 parts, calcium carbonate: 30 parts, N550: 50 parts, DOP: 20 parts, DCP: 5 parts, TAIC: 4 parts.
[0028] The preparation steps of the CM / CPE / CB elastic material of the present embodiment are as follows:
[0029] a. Adjust the roller pitch of the masticator to 0.5-1mm, control the temperature within the range of 80-100°C, mix CM, rare earth stabilizer, active MgO, and epoxy soybean oil in proportion and mix them on the masticator for 3 -5 minutes, use the triangular bag method to mix it evenly and remove it for use;
[0030] b. Mix CPE, rare earth stabilizer, active MgO, and epoxidized soybean oil in proportion and knead on a plastic mixer for 3-5 minutes; use the triangular bag method to make it evenly mixed and wrap it on a roll;
[0031] c. Put the product obtained in a into a plastic mixer, after 2-3 minutes of rolling ...
Embodiment 2
[0047] According to the following parts by mass: CM: 60 parts, CPE: 40 parts, rare earth stabilizer: 6 parts, active MgO: 10 parts, epoxy soybean oil: 10 parts, calcium carbonate: 30 parts, N550: 50 parts, DOP: 20 parts, DCP: 5 parts, TAIC: 4 parts. The difference between the proportioning of this embodiment and embodiment 1 is to use 60 parts of CM, 40 parts of CPE.
[0048] The preparation method and performance testing standard of this embodiment are the same as those of Embodiment 1, and will not be repeated here. The performance test results of the obtained CM / CPE / CB elastic material are shown in Table 1.
Embodiment 3
[0050] According to the following parts by mass: CM: 70 parts, CPE: 30 parts, rare earth stabilizer: 6 parts, active MgO: 10 parts, epoxy soybean oil: 10 parts, calcium carbonate: 30 parts, N550: 50 parts, DOP: 20 parts, DCP: 5 parts, TAIC: 4 parts. The difference between the proportioning of this embodiment and embodiment 1 is that 70 parts of CM and 30 parts of CPE are used.
[0051] The preparation method and performance testing standard of this embodiment are the same as those of Embodiment 1, and will not be repeated here. The performance test results of the obtained CM / CPE / CB elastic material are shown in Table 1.

Abstract
A CM / CPE / CB elastic material and a preparation method thereof, relating to a rubber material and a preparation method thereof, comprising the following components by mass: 50-80 parts of chlorinated polyethylene rubber (CM), chlorinated polyethylene (CPE) 50-20 parts, stabilizer 1-6 parts, acid absorbing agent 1-10 parts, epoxy soybean oil 1-10 parts, filler 30-50 parts, reinforcing agent 30-50 parts, plasticizer 20-50 parts, 2-5 parts of vulcanizing agent, 2-4 parts of cross-linking auxiliary agent. Since both CM and CPE are saturated, the present invention has good properties such as weather resistance, ozone resistance, and oil resistance. The elastic material and its preparation method of the present invention use a vulcanization temperature of 165°C, which solves the problems of long vulcanization time and low production efficiency. ; Increase the oil resistance and tensile strength of CM; it is a novel elastic material, and CM / CPE / CB blended materials have not been reported, which has important research significance.
Description
technical field [0001] The invention relates to a rubber material and a preparation method thereof, in particular to a CM / CPE / CB elastic material and a preparation method thereof. Background technique [0002] From the 1930s to the 1960s, many varieties of polymer elastomer materials were gradually researched and developed, which gradually met the needs of polymer elastomer materials at that time. However, as people's requirements for the properties and functions of polymer elastomer materials are increasing day by day, the performance of some synthetic polymer materials has been difficult to meet the needs. Therefore, since the 1970s, some new polymer elastomer materials have been continuously researched and developed through the modification of polymer elastomers. [0003] The modification of polymeric elastomer has the following three purposes: to endow the modified polymeric elastomer with certain high-tech properties and functions; to improve the processing performance...
