preparation example Construction

[0079] Based on the above, the program also provides a method for preparing a rubber part, which includes the following steps:

[0080] (1) Prepare the rubber strip body, which specifically includes at least mixing styrene-butadiene rubber, zinc oxide, stearic acid, paraffin oil and carbon black in an environment of 40-50°C, and then controlling the humidity of the mixing container to be lower than 50%. Add nano-bentonite for further mixing; then add ethylene thiourea as a vulcanizing agent and carry out mixing treatment at 80-100 ℃ for 20-25 minutes, and then shape it into a strip body blank and keep it at a constant temperature;

[0081] (2) Prepare a reinforcement layer, and then form several through holes on the surface of the reinforcement layer, which specifically include at least neoprene rubber, fatty acid, isopropanol, N-(1,3-dimethyl)butyl-N' -Phenyl-p-phenylenediamine was mixed uniformly at 45-55 °C, then tetramethylthiuram monosulfide was added as a vulcanizing age...

Embodiment 1

[0086] A kind of preparation method of rubber part, it comprises the steps:

[0087] (1) Prepare the rubber strip body, which specifically includes at least mixing 40 parts of styrene-butadiene rubber, 1.0 parts of zinc oxide, 0.4 parts of stearic acid, 3 parts of paraffin oil and 3 parts of carbon black in an environment of 40-50 °C, Then control the humidity of the mixing container to be lower than 50%, add 0.1 part of nano-bentonite for further mixing; then add 0.2 part of ethylene thiourea as a vulcanizing agent and carry out mixing treatment at 90 ℃ for 20-25 minutes, and then shape it into a rubber strip The body blank is kept at a constant temperature;

[0088] (2) Prepare the reinforcement layer, and then form several through holes on the surface of the reinforcement layer, which specifically include at least 30 parts of neoprene rubber, 0.2 parts of fatty acid, 1 part of isopropanol, 0.5 parts of N-(1,3-di Methyl)butyl-N'-phenyl-p-phenylenediamine was mixed uniformly...

Abstract

The invention relates to a rubber piece and application thereof in connecting pieces and protecting pieces. The rubber piece comprises a rubber strip body, a reinforcing layer and a plurality of waterbalance strips, the reinforcing layer is integrally formed on one end surface of the rubber strip body; and the plurality of water balance strips are embed and formed on the reinforcing layer in an array. The reinforcing layer is skillfully arranged on the rubber strip body, then the water balance strips are arranged on the reinforcing layer, then the water balance strips are formed into a whole,and when the rubber piece is used according to the humidity condition of an application scene, nano bentonite in the water balance strips can accumulate water under the condition of abundant humidity, and can actively absorb certain water in air under the condition of insufficient humidity. Then, the water loss of the reinforcing layer and the rubber strip body is alleviated to a certain extent along with the molecular migration, so that the situation that the molecular chain fracture reaction is intensified due to excessive water loss is avoided.

Description

technical field [0001] The invention relates to the technical field of preparation of functional rubber materials and its application, in particular to a rubber part and its application in connecting parts and protective parts. Background technique [0002] As one of the most commonly used polymer materials, rubber parts not only have excellent toughness and strength, but also are widely used in various industries due to low raw material costs and wide sources. With the promotion of applications, rubber The disadvantages of the parts are also highlighted. For example, after a certain period of use, the rubber surface will appear aging, cracking, discoloration and pulverization. Especially for some curved rubber parts, the performance will be greatly reduced after the surface is aged and cracked , and even after cracking, it is rapidly damaged in a short time. The existing research results on rubber aging mainly analyze that the main chain, side chain, and crosslinking bond ...
