Environment-friendly low-temperature-resistant fire-retardant complex plasticizer

Abstract

The present invention discloses an environment-friendly low-temperature-resistant fire-retardant complex plasticizer, comprising a matrix of the plasticizer, the matrix is prepared from sebacic acid, decyl alcohol, a catalyst, sodium carbonate and an auxiliary by exetrification, refining, filter-press refining and distilling. The weight ratio of sebacic acid to decyl alcohol is 1 to 1.57-5. The adding amount of the catalyst is 0.2-1% of the total weight of sebacic acid and decyl alcohol, the adding amount of sodium carbonate is 0.1-0.7% of the total weight of sebacic acid and decyl alcohol and the adding amount of the auxiliary is 0.3-1% of the total weight of sebacic acid and decyl alcohol. The plasticizer also comprises a low-temperature-resistant fire-retardant system. The plasticizer disclosed by the invention has the advantages of great environmental friendliness, high plasticizing efficiency, low-temperature resistance, low volatility, extremely low volatility and great stability.

Description

technical field

[0001] The invention relates to a plasticizer, in particular to an environment-friendly low temperature resistant flame retardant composite plasticizer. Background technique

[0002] Plasticizer is a kind of polymer material additives. There are many kinds. The most common variety is DEHP (commercial name DOP). DEHP chemical name is bis(2-ethylhexyl) phthalate, which is a colorless , Odorless liquid, widely used in industry. Plasticizer is a polymer material additive widely used in industry. Adding this substance in plastic processing can make it more flexible, easy to process, and can be legally used for industrial purposes. The existing ordinary low-temperature resistant plasticizers are easy to volatilize because of their small molecular weight and low boiling point. After long-term use, the plasticizers will precipitate from the product, which directly affects the low temperature resistance of the product and the life of the product. It is easy to harden...
