Abstract
The invention discloses a formula of flame-retardant polystyrene, which comprises polystyrene, flame retardants, a toughener, a compatilizer, an antistatic agent and a plasticizer, wherein the flame retardants are decabromodiphenyl ether and ammonium polyphosphate, the toughener is a styrene-butadiene thermoplastic elastomer, the compatilizer is grafted maleic anhydride, the antistatic agent is polyoxyethylene monostearate, and the plasticizer is diethyl phthalate. According to the formula of flame-retardant polystyrene, the flame-retardant polystyrene has the advantages of flame retardantcy, favorable toughness, favorable plasticity, favorable compatibility, static resistance and the like.
Description
Technical field
The present invention relates to a kind of plastic formula, be specifically related to a kind of prescription of fire retardant polystyrene.
Background technology
PS is combustible in essence material, through utilizing specific flame-retardant additive is joined in the polymkeric substance usually, or through with polystyrene foam parts and other building material combinations, realizes the good flame-retardance ability of polystyrene foam.In these product types and combination, polystyrene foam has obtained deserved good reputation as safe and very effective building/isolated material.
In recent years, exist to build and building in the flame retardant properties of increase of base mateiral, especially avoid the emerging demand of the measure of the property damage that fire causes.In addition, aspects such as other performances of fire retardant polystyrene such as toughness, consistency, anti-electrostatic all can't satisfy current needs of people.Therefore, a kind of novel flame-retardant PS is exactly our problem demanding prompt solution.
Summary of the invention
The object of the present invention is to provide a kind of fire-retardant, good toughness, plasticity is good, consistency is good, the prescription of anlistatig fire retardant polystyrene.
Technical scheme of the present invention is; A kind of prescription of fire retardant polystyrene comprises PS, fire retardant, toughner, compatilizer, static inhibitor and softening agent, and described fire retardant is decabromodiphynly oxide, ammonium polyphosphate; Toughner is styrene butadiene thermoplasticelastomer; Compatilizer is a maleic anhydride graft, and static inhibitor is a polyoxyethylene stearic acid ester, and softening agent is a diethyl phthalate.
In preferred embodiment of the present invention; Each composition weight percent of the prescription of described fire retardant polystyrene is that PS accounts for 70%-80%, and decabromodiphynly oxide accounts for 4%-6%, and ammonium polyphosphate accounts for 5%-7%; Styrene butadiene thermoplasticelastomer accounts for 4%-6%; Maleic anhydride graft accounts for 3%-4%, and polyoxyethylene stearic acid ester accounts for 2%-3%, and diethyl phthalate accounts for 2%-4%.
In preferred embodiment of the present invention; Each composition proportion of the prescription of described fire retardant polystyrene is that PS accounts for 76%, and decabromodiphynly oxide accounts for 4.3%, and ammonium polyphosphate accounts for 5.9%; Styrene butadiene thermoplasticelastomer accounts for 4.8%; Maleic anhydride graft accounts for 3.7%, and polyoxyethylene stearic acid ester accounts for 2.6%, and diethyl phthalate accounts for 2.8%.
According to the invention is a kind of prescription of fire retardant polystyrene, makes effects such as the fire retardant polystyrene that makes has fire-retardant, good toughness, plasticity is good, consistency is good, antistatic.
