Abstract

Relating to a plasticizer preparation method, the invention discloses a method for turning biomass cardanol into a chloroprene rubber internal plasticizer by click chemistry. The method includes: firstly reacting cardanol with propargyl bromide to prepare propargyl ether cardanol and chloroprene rubber with an azido structure, then carrying out click chemistry reaction to realize reaction of the propargyl ether cardanol and chloroprene rubber with an azido structure, thus realizing internal plasticization of chloroprene rubber. The method for internal plasticization of chloroprene rubber withthe natural biomass raw material by click chemistry reaction disclosed by the invention has the advantages that: the cardanol raw material is sufficient, the chemical reaction process is simple, the product has obvious plasticization effect, excellent thermal stability and near zero migration of plasticizer, therefore the chloroprene rubber internal plasticizer is a new product conforming to the green and environment-friendly circular economy concept and has very broad market prospects.

Description

technical field

[0001] The invention relates to a method for preparing a plasticizer, in particular to a method for converting biomass cardanol into a neoprene internal plasticizer through click chemistry. Background technique

[0002] Chloroprene rubber is an elastomer mainly obtained by homopolymerization or copolymerization of 2-chloro-1,3-butadiene monomer. Because its molecular chain contains a large number of polar chlorine atom groups, the double bond activity on the long chain is reduced, and the chloroprene rubber has great stability to non-polar substances, so that it has good physical properties. Mechanical properties, excellent performance in oil resistance, heat resistance, flame retardancy, chemical corrosion resistance and sealing. Widely used in industrial rubber products, wire and cable protective jackets, oil-resistant hoses, rubber seals and automobile manufacturing and other fields. However, chloroprene rubber has the disadvantages of poor cold resistan...
