Flame-retardant nanometer master batch for polyester plastic

Abstract

The invention discloses a flame-retardant nanometer master batch for a polyester plastic. The flame-retardant nanometer master batch comprises, by mass, 10-15% of a carrier, 40-60% of decabromodiphenylethane, 20-30% of diantimony trioxide, 6-10% of nano-sized magnesium hydroxide, 0.1-0.5% of a surface conditioning agent, 2-4% of a dispersant, 1-2% of a coupling agent and 0.1-1% of an antioxidant. The addition of the activated and modified nano-sized magnesium hydroxide makes the prepared flame-retardant master batch have an excellent dispersibility and an improved flame retardation property, and the flame-retardant master batch increases the flame retardation property of the polyester plastic and also guarantees the wear resistance, the rigidity, the toughness, the ageing resistance and the like of the polyester plastic. The flame-retardant master batch produced by adopting a production method in the invention can substitute a powdery flame retardant, can be directly added to the polyester plastic, can be used for wire drawing, extrusion, injection molding, blow molding or fiber granulation, and has the advantages of production operation simplification, production cost saving, material performance improvement, avoiding of the environmental pollution, benefiting for the clean production and the like.

Description

technical field [0001] The invention relates to a flame retardant master batch, in particular to a nano flame retardant master batch for polyester plastics. Background technique [0002] High-molecular polymers are organic compounds with extremely large relative molecular mass and repeating structural units formed by covalently bonding thousands of atoms. It is widely used as a high-performance material in many fields. [0003] Polyesters, such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), and polyethylene naphthalate (PEN), belong to a class of polymers It has excellent comprehensive performance and has been widely used in electronic appliances, automobile industry, mechanical equipment, packaging industry and so on. [0004] However, it has been found that polyesters, especially PET and PBT, have disadvantages such as insufficient toughness and flammability, so toughening and flame-retardant modification is usually required. However, most of the...

Problems solved by technology

[0004] However, it has been found that polyester, especially PET and PBT, has disadvantages such as insufficient toughness and flammability, so it is usually necessary to carry out toughening and flame retardant modification

However, most of the additives such as tougheners and flame retardants currently used are powders. If they are directly mixed in the production process of polyester, they will face problems such as uneven dispersion of raw materials and dust pollution. Therefore, it is necessary to prepare a masterbatch It can better solve the above-mentioned problems, and can also reduce production costs, simplify processes, etc.
