preparation example Construction

[0026] The synergistic metal-nonmetal catalyst is a composite of zirconocene dichloride and N-bromosuccinimide with a mass ratio of 6:1. Through zirconocene dichloride, a small amount of polyethylene glycol monooleate is coordinated into polyglyoxal monooleate compounds. Under the catalysis of N-chlorosuccinimide, polyglyoxal The monooleate compound is chlorinated into polyoxalyl chloride monooleate, and experiments have shown that polyoxalyl chloride monooleate forms a cross-linked belt between polyethylene glycol monooleate polymers, making polyethylene dichloride monooleate Alcohol monooleate polymer has stable conductivity, so that the coating has antistatic function, and the antioxidant compound is tetrakis (2,4-di-tert-butylphenol)-4,4'-biphenyl Phosphate ester prevents polyethylene glycol monooleate from being oxidized to make the flame retardant ineffective. The silicone flame retardant auxiliary agent is a carboxypolysiloxane flame retardant auxiliary agent, antistati...

Abstract

The invention relates to the technical field of preparation of halogen-free flame retardants, and discloses an anti-static polyethylene glycol monooleate halogen-free flame retardant. The anti-staticpolyethylene glycol monooleate halogen-free flame retardant includes the following experiment raw materials of polyethylene glycol monooleate, an antioxidant complex, an organosilicon flame retardantauxiliary and a synergistic metallic and non-metallic catalyst, and the polyethylene glycol monooleate is a polymer of oleic acid and polyethylene glycol. According to the anti-static polyethylene glycol monooleate halogen-free flame retardant, the synergistic metallic and non-metallic catalyst is a complex of zirconocene dichloride and N-bromosuccinimide, through the zirconocene dichloride, the small amount of polyethylene glycol monooleate is coordinated to form a polyglyoxal monooleate compound, under catalysis of N-chlorosuccinimide, the polyglyoxal monooleate compound is chloridized intopolyoxalyl chloride monooleate, a cross-linking belt is formed between the polyethylene glycol monooleate polymer by the polyoxalyl chloride monooleate, and thus the polyethylene glycol monooleate polymer has stable conductive performance.

Description

technical field [0001] The invention relates to the technical field of preparation of halogen-free flame retardants, in particular to an antistatic polyethylene glycol monooleate halogen-free flame retardant. Background technique [0002] The function of flame retardants is to make flammable polymers flame retardant. Mainly based on halogen flame retardants, but because halogen flame retardants produce more smoke and corrosive gases during pyrolysis or combustion, which cause serious pollution to the environment, the use of halogen flame retardants has been increasingly popular. There are many restrictions, and the existing flame retardants do not have the effect of making the material antistatic. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the invention provides an insulating cellulose-based halogen-free flame retardant, which solves the problem that the existing flame retardant contains toxic ha...
