Abstract

The invention relates to a rubber vulcanization bonding performance test sample preparation mold and sample preparation method. The preparation mold comprises a mold shell, an air chamber, a sample cavity and a middle mold. The air chamber is arranged in the mold shell and is connected with an external inflation device through a vent hole formed in the mold shell; the sample cavity is formed in the mold shell and located above the air chamber, the mold shell is provided with an opening structure used for opening the sample cavity, and the top surface of the inner wall of the sample cavity is provided with a first plane part; the middle mold is an elastic rubber diaphragm and is arranged between the sample cavity and the air chamber so as to divide the sample cavity and the air chamber into two independent cavities, a second plane part is arranged in the center of the middle mold, the second plane part is located under the first plane part, and the first plane part and the second plane part are of plane structures and are arranged in parallel; and a gap for accommodating and clamping a sample to be vulcanized is formed between the first plane part and the second plane part. The preparation mold can simulate the vulcanization pressure of a diaphragm vulcanization product, and the obtained sample can be used for measuring the influence of the vulcanization pressure change on the vulcanization bonding performance between rubber layers.

Description

technical field

[0001] The invention belongs to the technical field of vulcanized rubber adhesion detection, and in particular relates to a mold and a sample preparation method for rubber vulcanization adhesion performance test samples. Background technique

[0002] In the production process of rubber products that need to be multi-layered, the adhesion between different rubber layers has a very important impact on its use, which directly affects the reliability of the product application. In order to ensure that the adhesion meets the production requirements, before the production of the product, it is usually necessary to trial-manufacture a test sample to test the rubber adhesion performance, so as to optimize the production process parameters of the product.

[0003] However, in the production of diaphragm vulcanized products such as tires, air spring airbags, etc., even if the tested and optimized process parameters are used for production, the resulting products are st...
