flexible pvc materials grafted with castor oil derivative containing synergistic flame retardant groups of nitrogen and phosphorus

It is reported that replacing chlorine with palm oil derivatives containing nitrogen and phosphorus synergistic flame retardant base to increase the plastic PVC inside, that is, palm oil derivatives grafted onto the PVC matrix.
Low glass transition temperature (Tg)
Despite the reduction in thermal stability, modified PVC was produced.
However, the migration was completely suppressed.
PVC materials were modified by click reaction, peanut oil derivatives containing nitrogen and phosphorus synergistic flame retardant base were combined with PVC matrix to prepare flexible PVC materials with zero migration and enhanced flame retardant properties.
Plasticizer is an important plastic additive and has been widely used in the world.
It plays an important role in many types of plastic products.
As the main plasticizer in the plastic industry, plasticizer accounts for a large part of additives.
The fact is that the plasticizer industry is a large chemical industry based on petrochemical resources and centered on neighboring benzene ester.
It is easy to extract neighboring benzene ester with solvent.
The loss of plasticizer will reduce the performance of PVC products, and the performance of PVC products will change over time.
In addition, the flammable nature of phthalate ester further limits its application in plastic products with higher fire requirements.
Almost all of the neighboring benzene Ester comes from petrochemical resources, and this industrial model is unsustainable as fossil resources dry up.
To solve these problems, many alternatives have been studied to replace the O-benzene plasticizer. Bio-
Base plasticizer, such as waist fruit phenol, has been developed or commercial-
Base plasticizer, epoxy red flower oil, triester of glycerin and citric acid.
To improve the flame retardant properties of biological materials
A series of vegetable oil-based phosphate plasticizer has been synthesized in previous studies.
Castor Sesame oil is an important chemical raw material, which can be used to prepare different chemical products because of its different fatty acid structure.
Vegetable oil based additives containing phosphorus, Philippine ring and 1, 3, 5-Tris (2-hydroxyethyl)cyanuric acid (THEIC)
Different components were synthesized and used as plasticizer for the preparation of flame retardant PVC materials respectively.
However, all of these plasticizer are easily filtered out.
The use of internal plasticizer can avoid the migration of plasticizer from PVC products.
The internal plasticizer is connected to the chemical structure of the PVC matrix by chemical modification, because they are an inherent part of the PVC chain.
\"Click chemistry\" is an efficient chemical synthesis method for the preparation of internal plasticized PVC materials.
The preparation of inner plastic PVC material has always been the focus of attention.
Based on the above conclusion, the application of castor sesame oil based flame retardant plasticizer on PVC matrix can inhibit migration and improve its flame retardant performance.
We now report a method for the preparation of zero-migrating PVC materials using peanut oil derivatives containing nitrogen and phosphorus synergistic flame retardant base.
The new flexible PVC material has potential application value in the manufacture of non-migrating flame retardant PVC material.
