Background technique
Polystyrene foam plate abbreviation styrofoam, energy effective protection wall, intensity height, durable length, good heat insulating, often makees It is widely used in wall insulation system for thermal insulation material, but traditional styrofoam fire protecting performance is poor, belongs to combustible material.
Traditional styrofoam can generate a large amount of toxic gas in combustion, at the same melt drip phenomenon it is obvious that The generation of spot fire is easily caused, therefore, in order to improve the fire protecting performance of styrofoam, usually preparing in raw material to styrofoam Fire retardant is added.In the industrial production, halogenated flame retardant using more, but halogenated flame retardant can discharge cause in combustion Cancer substance " dioxin " and carbon tetrachloride pernicious gas, seriously affect the physical and mental health of the mankind.Subsequent people begin to use respectively Kind of inorganic fire retardants, the flame retarding efficiency of inorganic fire retardants is low, needs additional amount 40% or more if wanting to reach fire retardant grade, however nothing Compatibility between machine fire retardant and high molecular material is very poor, and the mechanical property of polymer will be reduced after a large amount of additions.
It is good therefore, it is necessary to study a kind of flame retardant property, while not influencing the styrofoam of mechanical properties of polymer again.
Summary of the invention
The purpose of the present invention one is to provide a kind of fire prevention styrofoam, while maintaining compared with high flame resistance, also has excellent Different tensile strength and impact strength.
Above-mentioned purpose of the invention has the technical scheme that
A kind of fire prevention styrofoam, in parts by weight, preparing raw material includes 60-75 parts of polystyrene, surfactant 0.5- 2.0 parts, 8-18 parts of silica, 9-16 parts of calcium carbonate, 15-25 parts of polyphenyl elastomer, 0.5-1.6 parts of dispersing agent, fiber reinforcement 14-26 parts of polyphenylene sulfide;
Wherein, fiber reinforcement polyphenylene sulfide preparation the following steps are included:
