Problems solved by technology

[0004] Synthetic rubber materials have excellent heat resistance, cold resistance, corrosion resistance and are less affected by environmental factors. Synthetic rubber materials can be used normally between 60 degrees and 250 degrees, but their main disadvantages lie in their tensile strength. The tensile effect is relatively poor, and the tear strength and mechanical properties are also relatively poor

Embodiment 2

[0050] Ethylene, chloroprene, isobutylene and acrylonitrile are mixed according to the ratio of 1:3:6:2. The filler of this ratio is added from the third feeding pipe 6, and the heating speed is fast, which can also be greatly improved. Improve the tensile effect of synthetic rubber; the reinforcing agent formed by mixing and polymerizing diisocyanate compounds and polyethers in a ratio of 3:4 should be fed from the third feeding pipe 6 and the second feeding pipe 7 respectively. Putting it in at intervals of three minutes before and after can greatly improve the tear strength of synthetic rubber;

Embodiment 3

[0052] Ethylene, chloroprene, isobutylene and acrylonitrile are mixed according to the ratio of 2:4:7:3. The filler of this ratio is added from the third feeding pipe 6, and the heating speed is fast, which can also be greatly improved. Improve the tensile effect of synthetic rubber; the reinforcing agent formed by mixing and polymerizing diisocyanate compounds and polyethers in a ratio of 3:4 should be fed from the third feeding pipe 6 and the second feeding pipe 7 respectively. Putting it in at intervals of three minutes before and after can greatly improve the tear strength of synthetic rubber;

Abstract

The invention discloses a manufacturing technology of high-quality synthetic rubber and an auxiliary tool of the manufacturing technology, and belongs to the field of a rubber manufacturing technology. The high-quality synthetic rubber comprises crude rubber to be treated. The manufacturing technology comprises the steps of performing plasticating, performing intermixing, performing calendering, performing extrusion, performing shaping and performing vulcanization, wherein the plasticating step comprises the following steps of performing rubber drying, performing rubber cutting and performingrubber cracking; and in the intermixing step, an improved-type compounding agent and the auxiliary tool are used, wherein the auxiliary tool comprises a first stage mixing cylinder, a second stage mixing cylinder and a mixing discharging head, the mixing discharging head is fixedly connected to the lower end of the second stage mixing cylinder, the first stage mixing cylinder is arranged at the upper end of the second stage mixing cylinder, a first feeding opening is formed in the side end of the first stage mixing cylinder, a first feeding pipe is connected to the first feeding opening, a second feeding opening is formed in the side upper end of the second stage mixing cylinder, a second feeding pipe is connected to the second feeding opening. The improved-type compounding agent cooperates with the specific auxiliary tools, so that the stretching effect and the tear resistance intensity of the synthetic rubber can be improved to a great extent.

Description

technical field [0001] The invention relates to the field of rubber manufacturing technology, more specifically, to a high-quality synthetic rubber manufacturing technology and its auxiliary tools. Background technique [0002] Synthetic rubber is a highly elastic polymer that is artificially synthesized. Also known as synthetic elastomer, it is one of the three major synthetic materials, and its output is only lower than that of synthetic resin (or plastic) and synthetic fiber. Rubber is a necessary material for the manufacture of aircraft, warships, automobiles, tractors, harvesters, irrigation and drainage machinery, medical equipment, etc. According to different sources, rubber can be divided into natural rubber and synthetic rubber. There are a few varieties of synthetic rubber that are similar to natural rubber in performance, and most of them are different from natural rubber, but both are high-elastic polymer materials, and generally need to be vulcanized and proce...
