Liquid Rubber is a kind of viscous liquid with molecular weight between 2000 and 10000, which can form a three-dimensional network structure through proper chemical reaction, thus, the oligomer with similar physical and mechanical properties to the ordinary Vulcanizate was obtained./nThe characteristics of liquid rubber are:
1) the molecular weight should be appropriately small to maintain a flowing state;
2) to be able to produce cross-linking, and the physical and mechanical properties of the cross-linking compounds can reach the level of ordinary vulcanizates./nThere are many types of liquid rubber, mainly in two categories:
1) according to whether there is functional group and its location, it is divided into non-functional group liquid rubber, random functional group liquid rubber and end functional group liquid rubber. In particular, the two end groups of liquid rubber with active functional groups, through chain extension or cross-linking at room temperature for a short time to achieve three-dimensional structure, greatly improve the physical properties, can achieve or close to the inherent characteristics of various synthetic rubber;
2) according to the main chain structure, they are divided into diene liquid rubber (including liquid polybutadiene rubber, liquid isoprene rubber, liquid nitrile rubber) , chain olefin liquid rubber, polyurethane liquid rubber, liquid silicone rubber, liquid polysulfide rubber and liquid fluorine rubber.
Liquid rubber
Liquid rubber is an oligomer of anionic or coordinated anionic solution, which is a good processing aid in the rubber industry, such as Plasticizer, vulcanizing aid, modifier, etc. , potting agents, coating agents and asphalt modifiers for the electronic industry. It is widely used in adhesives, coatings, sealing caulking materials, all kinds of industrial elastic products. In addition, the liquid rubber may also use the reactive operation oil, improves the solid rubber processing property, enhances the vulcanized rubber physical and mechanical properties
