Problems solved by technology

[0004] Researchers in various countries have done a lot of research on soybean oil-based plasticizers, but because soybean oil is a flammable glyceride, the application of soybean oil-based plasticizers is limited, and soybean oil-based flame retardant plasticizers are limited. There are relatively few studies on plasticizers. By adding flame retardant elements and groups to soybean oil molecules, the flame retardancy of soybean oil-based plasticizers and the flame retardancy of polyvinyl chloride products can be greatly improved.
In the past, the main raw materials for the synthesis of flame retardant plasticizers by scholars were all from fossil resources, which did not meet the requirements of sustainable development.

Abstract

The invention provides a soybean-oil-based flame-retardant plasticizer, and a preparation method and application thereof. The soybean-oil-based flame-retardant plasticizer is prepared from diethyl phosphate and epoxidized soybean oil by reaction. The soybean-oil-based flame-retardant plasticizer is prepared by adopting a structural modification method; diethyl phosphate containing a flame-retardant element P is added into the structure of soybean oil; the obtained soybean-oil-based flame-retardant plasticizer is applied in preparation of a flame-retardant type polyvinyl chloride product; and under the condition of no loss of mechanical performance, the plasticizer has higher flame-retardant property, and oxygen index can reach 24 to 33%. The soybean-oil-based flame-retardant plasticizer provided by the invention has extensive application prospects in the fields like plastics, rubbers, military products, textiles, conveyer belts and various building materials which have high requirements for flame-retardant performance.

Description

technical field [0001] The invention belongs to the technical field of soybean oil-based flame-retardant plasticizers, and mainly relates to soybean oil-based flame-retardant plasticizers, their synthesis methods and their application in polyvinyl chloride products. Background technique [0002] The synthesis of polyvinyl chloride plasticizers from soybean oil, a renewable biomass resource, has received extensive attention in recent years. Its main advantages are that soybean oil is non-toxic, environmentally friendly, biodegradable, and the raw material is renewable. my country is rich in soybean oil resources. Under the situation of increasingly scarce oil resources, it is undoubtedly a good method to use soybean oil as raw material to produce functional plasticizers. Currently, the most widely used soybean oil-based plasticizer is epoxidized soybean oil. [0003] Polyvinyl chloride is one of the five general-purpose synthetic resins in synthetic materials, and its outpu...
