Abstract

The invention discloses an additive for plastics, application thereof, and a flame-retardant polymer molding composition composed of the same. Specifically, the additive comprises: A. diethyl aluminum phosphinate; and B. homologues, the molar content of which in the total additive is 0.001-0.78%. The homologues are ethyl butyl aluminum phosphinate, butyl butyl aluminum phosphinate, ethyl hexyl aluminum phosphinate, butyl hexyl aluminum phosphinate and / or hexyl hexyl aluminum phosphinate. The additive for plastics provided by the invention can be added into a polymer, has small corrosion to the screw of a mixing assembled unit during processing and small damage to surrounding polymers. Compared with plastic additives with a high content of homologues, the additive provided by the invention has a high effective P content and good flame retardant performance, thus greatly broadening the application range of the plastic additive in the market.

Description

technical field [0001] The invention relates to an additive for plastics, in particular to an aluminum diethylphosphinate containing a homologue in a specific range, its application, and a flame-retardant polymer molding composition composed of it. Background technique [0002] Aluminum diethylphosphinate, as a new type of halogen-free flame retardant with high thermal stability and excellent flame retardancy, is widely used in polymers. However, it has been found in practical applications that during the processing of the flame retardant polymer molding composition added with aluminum diethylphosphinate, it will cause particularly serious corrosion to the screw of the compounding assembly device and damage the surrounding polymers. Doing damage, inter alia, can lead to degradation of polymers. [0003] At the same time, the incomplete combustion of the flame-retardant polymer will cause the problem of burning smoke. To solve this problem, various solutions have been propo...
