High-strength plasticizer

Abstract

The invention discloses a high-strength plasticizer which is formed by mixing the following components in weight percent: 13% to 14% of polyvinyl chloride, 0.2% to 0.3% of glycerine, 10% to 20% of diethylene glycol, 10% to 20% of octyl ethylene epoxide, 0.5% to 0.7% of methene nonadecane and the balance of trimethylene ether. The high-strength plasticizer has the advantages of reasonable formula, low cost, low plasticization temperature, good tackiness, low sticky residue and stronger weather resistance.

Description

technical field [0001] The invention relates to a plasticizer, in particular to a high-strength plasticizer. Background technique [0002] With conventional plasticizers commonly used at present, the flexibility and elasticity of molded products change with time, which affects product quality and makes the surface of the product sticky. Moreover, conventional plasticizers have poor weather resistance and have obvious limitations in use. Chemical stability becomes an important criterion for the performance of plasticizers. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a high-strength plasticizer with low cost, low plasticizing temperature, good adhesion, low residual viscosity and strong weather resistance. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a high-strength plasticizer, whic...
