Causes of damage to tensile strength of insulating rubber sheet

The raw material of insulating rubber plate is rubber, so the ductility and plasticity of insulating rubber plate have more advantages than other plates. In addition to the ductility and plasticity, the insulating rubber plate also has the advantages of insulating layer, ground anti-skid, wear resistance and so on, which are favored by the people. Because of the high demand of rubber sheet in the sales market, there are more and more rubber sheet manufacturers. But recently, many friends told me that the tensile strength of rubber sheet is sometimes good, sometimes not very good. What's the reason? Let's get to know about it!
1. From the secret recipe design level, the key includes the type of raw rubber, vulcanized rubber management system and filler type and usage. The secret formula of high tensile strength should be crystalline rubber, such as rubber, chloroprene rubber or chlorosulfonated high pressure polyethylene. Rubber composition is generally about 60%.
2. In the whole mixing process, the specific fillers should be selected and evenly dispersed. The amount of specific fillers should be used as much as possible.
3. The tensile strength of insulating rubber sheet is related to the structure of rubber. When the dose is very long, the secondary valence bond between molecular structures is not large. All the other elements that harm the interaction between molecular structures are those that harm the tensile strength.
4. Tensile strength is also related to temperature. The tensile strength at high temperature is much lower than that at room temperature. The tensile strength is related to the crosslinking density. With the increase of crosslinking density, the tensile strength increased. When the low value occurs, the crosslinking density will increase again and the tensile strength will decrease greatly.
In order to better add a variety of mutual compounding agents to the insulating rubber sheet, the raw rubber should be melted to improve its plastic deformation. Then, carbon black, various rubber modifiers and rubber are mixed to produce rubber plastic particles. The extruded plastic particles produce a certain shape of preform, which is then mixed with the injection molding, the extrusion molding and the extrusion molding Plywood or plywood textile raw materials fusion to produce semi-finished processing, vulcanized rubber, semi-finished processing with ductility is made into high elastic products.
