Rubber shoes material structure can be divided into three sections

Shoes, shoes materials rubber is an indispensable part of, and dosage is large and stable, the current general classification can be divided into natural rubber and synthetic rubber, in the use of the classification of the above and divided into general type and special type two kinds, and also on the structure of rubber shoes material is divided into three sections. Linear structure is the common structure of unvulcanized rubber. Due to the large molecular weight, under the action of external force, group that is fine. When the external force, removal of the external force, the degree of entanglement of the fine mass change, molecular chain rebound, a strong tendency of recovery, this is the origin of the high elastic rubber. Branched chain structure is the accumulation of the branched chain of rubber macromolecule chain formed gel. Gel properties and processing of rubber. , mixing with various compound area, often get in the gel forming local blank, the formation of the reinforcing and crosslinking, and become a weak part of the product. Crosslinking structure is linear molecules through some atoms or groups of atoms Bridges connected to each other, form a three-dimensional network structure. Along with the vulcanization process, continuously strengthen the structure. So, chain segments free ability to drop, plasticity and elongation decreased, strength, elasticity and hardness, compression permanent deformation and swelling degree drop.
