Embodiment 1

[0035] Compared with Example 4, the physical and mechanical properties of chloroprene rubber and natural rubber are significantly improved; and the increase in the amount of accelerator TM808 and tert-butylphenol formaldehyde resin is beneficial to the improvement of physical and mechanical properties.

Embodiment 2

[0036] Embodiment 2 is compared with embodiment 5, and the increase positive sulfur time of T-ZnO whisker delays; But the reduction of the consumption of TM808 and tert-butylphenol formaldehyde resin makes its physical and mechanical properties reduce to some extent, and its rule is as implementing The comparison of example 1 and embodiment 4.

Embodiment 3

[0037] Embodiment 3 compares with embodiment 1, embodiment 2, embodiment 4 and embodiment 5, and the consumption of TM808 is bigger for the physical and mechanical properties of sizing material, followed by the influence of T-ZnO whisker; Comparative embodiment 3 It can be seen from Example 5 that the larger the dosage of T-ZnO whiskers is not the better, it has a suitable dosage.

[0038] The vulcanization and performance indicators of the rubber compound in Example 1 at 100°C×10 minutes and 20°C×7 days (room temperature) are shown in Table 2, which shows that the rubber compound in the embodiment can fully meet the requirements of large-scale products at room temperature for more than 7 days. performance requirements.

[0039]It can be seen from Table 1 and Table 2 that the rubber compound of the present invention exhibits better room temperature / low temperature vulcanization characteristics, and has good scorch performance, that is, Tc10 / min is appropriate, and the normal v...

Abstract

The invention discloses a room temperature / low temperature vulcanized chloroprene rubber sizing material, which relates to rubber. The rubber sizing material is obtained by mixing and processing the following components in parts by mass: 100-30 parts of chloroprene rubber, 0-70 parts of natural rubber, 0-1 part of sulfur S, 4-7 parts of T-ZnO crystal whiskers, 1-6 parts of magnesium oxide, 0-3 parts of TM808, 0.5-1.5 parts of accelerating agent TMTD (Tetramethylthiuram Disulfide), 20-50 parts of tert-butyl phenol formaldehyde resin, 1-6 parts of stearic acid and the balance of compound anti-ageing system consisting of 4010Na and D, carbon black and a paraffin aid, wherein the sulfur S, the T-ZnO crystal whiskers and the magnesium oxide jointly serve as a dual vulcanizing agent, and the TM808 and the accelerating agent TMTD jointly serve as a compound accelerating agent. The chloroprene rubber sizing material obtained by the invention can be vulcanized at room temperature / low temperature, has high scorching property, high adhesion on a framework material and the advantages of ageing resistance, high physical and mechanical performance, high ozone resistance, high oxidation resistance, combustion resistance and the like, and is particularly suitable for the production of large-sized rubber products or the construction of field vulcanization.

Description

technical field [0001] The invention relates to a rubber, in particular to a room temperature / low temperature vulcanized chloroprene rubber material, which is especially suitable for the production of large rubber products or the construction of on-site vulcanization. Background technique [0002] Chloroprene rubber (CR) is an elastomer produced by α-polymerization of chloroprene (that is, 2-chloro-1,3-butadiene) as the main raw material. It has good physical and mechanical properties, aging resistance, oil resistance, and Heat resistance, flame resistance, sunlight resistance, ozone resistance, acid and alkali resistance, and chemical reagent resistance. [0003] It can be used to produce cables, rubber sheets, ordinary and oil-resistant rubber hoses, oil-resistant rubber boots, air guide tubes, rain cloths, tent cloths, conveyor belts, conveyor belts, rubber seals, capsule air cushions, boat shafts, etc., widely used in machinery, automobiles, and textile industries , che...
