Embodiment 1

[0026] According to the following parts by mass: CM: 80 parts, PVC: 20 parts, rare earth stabilizer: 6 parts, active MgO: 10 parts, calcium carbonate: 30 parts, N550: 40 parts, DOP: 50 parts, DCP: 3 parts, TAIC: 2 servings.

[0027] The preparation steps of the CM / PVC elastic material of the present embodiment are as follows:

[0028] a. Mix PVC, rare earth stabilizer, and DOP in proportion and add them together into the high-speed mixer. The temperature in the high-speed mixer is controlled within the range of 90-100°C, and take out after the materials are fluffy and mixed evenly;

[0029] b. Adjust the roller pitch of the masticator to 0.5-1mm, put the result in a into the masticator, control the temperature of the masticator within the range of 130-150°C, and roll and knead for 2-3 minutes. The triangular bag method makes the mixing obtained in a uniform;

[0030] c. Mix the obtained in b with CM, rare earth stabilizer, and active MgO in proportion and knead on a plastic ...

Embodiment 2

[0046] According to the following mass parts: CM: 70 parts, PVC: 30 parts, rare earth stabilizer: 6 parts, active MgO: 10 parts, calcium carbonate: 30 parts, N550: 40 parts, DOP: 50 parts, DCP: 3 parts, TAIC: 2 servings. The difference of the proportioning of the present embodiment and embodiment 1 is to use 70 parts of CM, 30 parts of PVC.

[0047] 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 / PVC / CB elastic material are shown in Table 1.

Embodiment 3

[0049] According to the following mass parts: CM: 60 parts, PVC: 40 parts, rare earth stabilizer: 6 parts, active MgO: 10 parts, calcium carbonate: 30 parts, N550: 40 parts, DOP: 50 parts, DCP: 3 parts, TAIC: 2 servings. The difference of the proportioning of the present embodiment and embodiment 1 is to use 60 parts of CM, 40 parts of PVC.

[0050] 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 / PVC / CB elastic material are shown in Table 1.

Abstract

The invention discloses a CM (Chylomicron) / PVC (Polyvinyl Chloride) / CB (Conjugated Bilirubin) elastic material and a preparation method thereof, and relates to a rubber elastic material and a preparation method thereof, wherein the preparation method comprises the following steps: a, mixing the PVC, a stabilizer and a plasticizer in proportion and then adding into a high-speed mixer; adjusting roller spacing of a plasticator to 0.5 millimeter-1 millimeter, and adding the substances obtained in the step a into the plasticator; mixing the CM, the stabilizer and an acid-acceptor in proportion and mixing for 3 minutes-5 minutes in the plasticator; respectively adding a filling agent, a reinforcing agent and the plasticizer, packing for 6 times-8 times by a triangular packing method, staying under the room temperature environment; placing the obtained rubber compound for 24 hours; and vulcanizing the rubber compound obtained in the step d by using a flat-plate vulcanizing agent under 10 MPa at a temperature of 165 DEG C. According to the invention, carbon black is used as the reinforcing agent, so that performance of the blended rubber is better, 165 DEG C vulcanizing is realized, a problem that vulcanizing time is long is solved, production efficiency is improved, oil resistance of the CM is increased, material cost is lowered, and mechanical performance is better.

Description

technical field [0001] The invention relates to a rubber elastic material and a preparation method thereof, in particular to a CM / PVC / CB elastic material and a preparation method thereof. Background technique [0002] Since the 1920s, the vigorous development of polymer synthesis science has led to the gradual research and development of many varieties of polymer elastomer materials from the 1930s to the 1960s, which gradually met the needs of polymer elastomer materials at that time. . However, with people's increasing demands on the properties and functions of polymer elastomer materials, the performance of 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 polymer elastomers has the following three purposes: to endow the modified polymer elastomers with certain high-te...
