Environment-friendly flame-retardant polystyrene composite material and preparing method thereof

Abstract

The invention discloses an environment-friendly flame-retardant polystyrene composite material. The environment-friendly flame-retardant polystyrene composite material is prepared from, by weight, 60-96 parts of PS resin, 0.1-20 parts of a fire retardant and 0.1-20 parts of a flame retardant synergist, wherein the fire retardant is at least one of decabromodiphenyl ethane, brominated epoxy resin,tri cyanurate, ethylene ditetrabromo-phthalic imide, tetrabromo bisphenol A and eight bromo ether; the flame retardant synergist is at least one of antimonous oxide and talcum powder. In the environment-friendly flame-retardant polystyrene composite material, through the synergistic interaction effect of the fire retardant and the flame retardant synergist, the composite material has the good flame resistance; as a compatilizer and a toughening agent are added, the composite material has the good yellowing resistance and toughness. The invention also discloses a preparing method for the environment-friendly flame-retardant polystyrene composite material.

Description

technical field [0001] The invention relates to a polystyrene composite material and a preparation method thereof, in particular to an environment-friendly flame-retardant polystyrene composite material and a preparation method thereof. Background technique [0002] In today's society, the requirements for fire safety of materials are getting higher and higher. Since the combustion of commonly used flame retardants such as decabromodiphenyl ether produces a large amount of black smoke, and even the generation of strong carcinogen dioxin, which causes great harm to the human body, laws and regulations are generally issued in various countries to restrict certain flame retardants. usage of. In areas such as household appliances, there is a risk of short-circuit fire due to contact with electricity, so materials are required to be flame-retardant. [0003] The flame retardants commonly used in environmentally friendly flame-retardant PS systems have the disadvantages of easy ...
