Embodiment 1

[0020] A water-swellable rubber, prepared from the following raw materials in parts by weight: 100 parts of EPDM rubber, 50 parts of carbon black, 5 parts of zinc oxide, 1 part of stearic acid, 0.8 parts of sulfur, accelerator CZ 2.5 parts, 0.4 parts of accelerator TT, 2 parts of anti-aging agent RD, 5 parts of calcium oxide, 3 parts of super oil-absorbing resin.

[0021] The preparation method is as follows: put the EPDM rubber into a Φ130mm×300mm type open mill for mastication, and after the surface of the rubber material is smooth, add carbon black, zinc oxide, anti-aging agent RD, calcium oxide, and accelerator CZ in order to promote Agent TT to prepare a mixture. A super oil-absorbing resin was added to the prepared mixed material, and further kneaded to obtain a mixed material. Add sulfur to the prepared mixed material, make triangular bags, roll, and knead the rubber material evenly. After the prepared rubber material is parked for 15-18 hours, it is scorched and vulc...

Embodiment 2

[0023] A water-swellable rubber, prepared from the following raw materials in parts by weight: 100 parts of EPDM rubber, 50 parts of carbon black, 5 parts of zinc oxide, 1 part of stearic acid, 0.8 parts of sulfur, accelerator CZ 2.5 parts, 0.4 parts of accelerator TT, 2 parts of anti-aging agent RD, 5 parts of calcium oxide, 3 parts of super oil-absorbing resin.

[0024] A water-swellable rubber was prepared in the same manner as in Example 1.

Embodiment 3

[0026] A water-swellable rubber, prepared from the following raw materials in parts by weight: 100 parts of EPDM rubber, 50 parts of carbon black, 5 parts of zinc oxide, 1 part of stearic acid, 0.8 parts of sulfur, accelerator CZ 2.5 parts, accelerator TT0.4 parts, anti-aging agent RD 2 parts, calcium oxide 5 parts, super oil-absorbing resin 4 parts.

[0027] A water-swellable rubber was prepared in the same manner as in Example 1.

Abstract

The invention belongs to the technical field of preparation of rubbers, and relates to a rubber capable of expanding after contact of water, and a preparation method thereof, wherein the rubber is prepared from the following raw materials by weight: 80-100 parts of ethylene propylene diene monomer, 40-60 parts of carbon black, 5-8 parts of an active agent, 1-4 parts of stearic acid, 0.5-2 parts ofa vulcanizing agent, 1-4 parts of an accelerant CZ, 0.1-0.5 part of an accelerant TT, 1-4 parts of an anti-aging agent RD, 1-5 parts of a defoamer, and 1-4 parts of a modification agent. The rubber of the present invention has various physical and mechanical properties of ordinary rubbers, can expand after contact of water, and further has advantages of good water stop effect and the like.

Description

technical field [0001] The invention belongs to the technical field of rubber preparation, and relates to water-swellable rubber and a preparation method thereof. Background technique [0002] Water-swellable rubber is a new type of functional material, which plays an important role in removing oil pollution and improving the living environment of human beings. The oil-swellable rubber prepared with high oil-absorbing resin as a modifier can be widely used in chemical industry, oil and gas exploration and other leak-proof and sealing occasions that are in contact with oil products, and has a good application prospect. At the same time, the rubber with water swelling can be used alone in the water environment. [0003] However, there are few domestic researches on swelling rubber with water swelling ability. However, the oil-water-swellable rubber prepared by blending is low in terms of water absorption ratio and mechanical properties. The blending process and co-vulcanizat...
