Abstract

The invention discloses itaconate / butadiene copolymer type bioengineering rubber and a preparation method thereof, and belongs to the field of bioengineering rubber. The bioengineering rubber provided by the invention is formed by performing chemical crosslinking on a copolymer formed through emulsion polymerization of itaconate and butadiene, the number-average molecular weight of the itaconate / butadiene copolymer is 53000-1640000, and the weight-average molecular weight of the itaconate / butadiene copolymer is 110000-2892000. The preparation method comprises the following steps: an itaconate monomer and butadiene are subjected to emulsion polymerization to prepare the itaconate / butadiene copolymer; then, the itaconate / butadiene copolymer is subjected to the chemical crosslinking to prepare the bioengineering rubber, wherein the chemical crosslinking process can be implemented by adding a traditional sulfuration / accelerant sulfuration system. The bioengineering rubber provided by the invention is high in molecular weight and low in glass-transition temperature, can be sulfurized by the sulfuration / accelerant sulfuration system, is enabled to have the physical and mechanical properties and processing performance equivalent to those of the conventional synthetic rubber, and can meet the requirements for engineering application such as tire treads and conveyor belts.

Description

Technical field: [0001] The invention relates to a method for preparing itaconate / butadiene copolymer type bioengineering rubber initiated by a redox initiation system through emulsion polymerization under low temperature conditions. Background technique: [0002] As people pay more and more attention to issues such as the depletion of fossil resources and environmental pollution, making full use of low-carbon, environmentally friendly and renewable resources has attracted more and more attention from all over the world. Due to its unique high elasticity, rubber is widely used in various fields of national defense and people's livelihood, and rubber materials are called important strategic resources. However, the rubber synthesis industry has long relied heavily on non-renewable fossil resources. At the same time, the accelerated consumption of non-renewable resources has increased the cost of rubber synthesis, accelerated environmental damage, and limited the development of...
