Abstract

A rubber composition used for manufacturing undersoles of rubber shoes and a preparation method thereof belong to the technical field of rubber processing. The invention is characterized in that the rubber material adopts high vinyl polybutadiene rubber and styrene butadiene rubber or isoprene rubber, a prefabricated spherical elastomer is added for adjusting elasticity, white carbon black or carbon black is added for reinforcing the system, and vulcanization is carried out for preparation of the undersoles of rubber shoes. The prepared undersoles of rubber shoes have advantages of light weight, excellent aging resistance, wet skid resistance and wear resistance, good flexure and tear resistance, mild resilience, and more excellent anti-vibration performance for human body. The rubber composition is an ideal rubber material for preparation of high-performance undersoles of rubber shoes.

Description

technical field [0001] The invention discloses a rubber composition used for manufacturing rubber shoes outsoles and a preparation method thereof, belonging to the technical field of rubber processing. Background technique [0002] With the development of rubber shoes industry, higher requirements are put forward for the quality, comfort, sanitation and safety of rubber shoes. Light weight is a common requirement for all rubber shoes. It not only means saving raw materials and reducing costs, but more importantly, it can reduce the physical strength and fatigue of users when walking. In order to find rubber for rubber shoes that can meet this performance requirement, a lot of scientific research work has been done at home and abroad, and great progress has been made, among which high vinyl butadiene rubber (HVBR) is one example. Compared with other rubber types, high vinyl butadiene rubber has high wet skid resistance, low dynamic heat generation, light weight and excellent...
