Binding agent used between textile fabrics and rubber

Abstract

The invention discloses a binding agent used between textile fabrics and rubber and a preparation method thereof. The binding agent is helpful to improve the binding force between the textile fabrics and the rubber and is capable of effectively improving the binding force between the textile fabrics and the rubber. The binding agent is prepared from raw materials of resorcinol, hexamine and distilled water. The invention has the advantages that: the rubber is added into the binding agent, after the rubber is compounded with the textile fabrics, the binding agent can participate in the vulcanization during the vulcanization to ensure that a stable and firm chemical bond is formed between the rubber and the texture fabrics, the problem of purely depending on a low binding force formed between rubber high polymers and the textile fabrics through a physical action is overcome, a binding force formed between the textile fabrics and the rubber under a physical action exists and a binding force formed under a chemical action also exists. Tests prove that after the rubber is added in the binding agent, the binding force between the rubber and the textile fabrics can be improved by 100-150 percent, and the flexibility and the impact resistance can be improved by 10-15 percent.

Description

technical field [0001] The invention belongs to the technical field of rubber chemical products and relates to an adhesive, in particular to an adhesive used between textiles and rubber. Background technique [0002] The bonding between textiles and rubber can be seen everywhere. For example, the rain cloth used in rubber raincoats is produced by combining cloth and rubber. It is characterized by the flexibility of textiles and the waterproof and air-blocking properties of rubber. nature. Another example: car tires are made of cord fabrics and rubber layers interlaced and laminated. It will be subject to alternating stress, if the adhesion between the cord fabric and the rubber is slightly poor, it will directly affect the load and service life of the tire, and even threaten the lives of the entire vehicle and passengers Safety. [0003] At present, the bonding between textiles and rubber is mainly through rolling, slicing, and crushing of rubber to destroy the macromolec...

AI Technical Summary

Problems solved by technology

[0003] At present, the bonding between textiles and rubber is mainly through rolling, slicing, and crushing of rubber to destroy the macromolecular chain of rubber and the gel in the polymer, so that the molecular weight becomes smaller and the plasticity increases. Under the action of mechanical device rolling pressure and shear force, the rubber polymer is penetrated into the textile to form a physical bond, but the degree of adhesion is small. Therefore, the product is prone to rubber and textile in the process of use. The bonding is not firm, or even the two are separated and fallen off, which directly affects the product quality and service life, and brings a lot of inconvenience to people's life and work.
