Abstract

The invention discloses a preparation method and application of a bio-based flame-retardant compatilizer for PBAT (poly (butylene adipate-co-terephthalate)). The bio-based flame-retardant compatilizer is prepared by the following process: carrying out grafting reaction on Fischer-Tropsch wax and maleic anhydride to obtain Fischer-Tropsch wax acid, dispersing the prepared Fischer-Tropsch wax acid and soybean protein isolate, and reacting with phytic acid in a solution to obtain the bio-based flame-retardant compatilizer. According to the bio-based flame-retardant compatilizer prepared by the invention, a novel flame retardant chemical structure with synergistic flame-retardant and compatible effects is obtained by using raw materials from bio-based sources, and the flame retardant does not influence the biodegradability of PBAT, can also play a lubricating role in the processing process, inhibits hydrolysis in the processing process, and has the advantages of favorable flame retardancy, favorable flame retardancy, favorable flame retardancy, favorable flame retardancy, favorable flame retardancy, favorable flame retardancy, favorable flame retardancy, favorable flame retardancy, favorable flame retardancy, favorable flame retardancy and favorable flame retardancy. And the method has very important practical significance for broadening the actual application scene of the PBAT.

Description

technical field [0001] The invention relates to a preparation method and application of a bio-based flame retardant compatibilizer for PBAT, belonging to the technical field of polymer materials. Background technique [0002] At present, the copolymer of butylene adipate and butylene terephthalate (PBAT), as a biodegradable polymer, has received extensive attention in the industry, and is considered to be the most promising biodegradable polymer in the market. One of the degradable polymers. PBAT has the characteristics of both PBA and PBT. It has good mechanical properties and good heat resistance. It is widely used in disposable lunch boxes, films and other fields. However, its poor flame retardancy has also become a restrictive factor for its comprehensive application. At present, the nitrogen-phosphorus synergistic flame retardant system is considered to be the best flame retardant system for PBAT. As an organophosphorus compound extracted from plant seeds, phytic aci...
