Abstract

The invention discloses a method for preparing a flame retardant by utilizing a modifying technology and a compounding technology, and belongs to the technical field of flame retardant preparation. The flame retardant is prepared from the following raw materials: polybutylene terephthalate, antimonous oxide, magnalium layered double hydroxide, subcarbonate, organic ammonium bromide, methyl silicone oil, acrylic ester and a dispersant. The flame retardant is prepared by polybutylene terephthalate drying, surface modification of the antimonous oxide, surface modification of magnalium layered double hydroxide, mixing, granulating, screening, drying and the like. According to the method, the modifying and synergizing technical means is adopted, the addition amount of the flame retardant is 10-20 percent, the antimony part is substituted by comprehensive compounding; and in the development of the product in the invention, the consumption of antimony can be greatly reduced, and the utilization limit of the antimony resource can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of preparation of flame retardants, and in particular relates to a method for preparing flame retardants using modification technology and compounding technology. Background technique [0002] The ideal goal of people using flame retardants is to use a small amount of flame retardants to achieve high-efficiency flame retardancy. The use process is simple, low cost and durable, with good stability, non-toxicity, and safety. In practical applications, a single-component flame retardant cannot meet all the above requirements, and compounding methods are required to integrate the performance advantages of various flame retardants to meet people's expected use requirements. Nowadays, people's awareness of environmental protection is gradually increasing. While paying attention to their own health, they actively respond to the government's call and pay attention to environmental protection. Since the 18th Nationa...
