Material have increasingly higher demands, PS limits PS and answers to a certain extent since poor fire, scraping and wiping resistance performance are bad
The application range of condensation material.
At present, the most common method for improving the scratch resistance of PS is to add talcum powder, calcium carbonate, glass microballoon wherein
Deng inorganic filler, the common method for improving PS anti-flammabilitys is addition fire retardant, but this method improve its scratch resistance and
While anti-flammability, its physical property has the reduction of many degree.
The content of the invention
The object of the present invention is to provide a kind of fire-retardant scratch-resistant PS composite materials and preparation method thereof, to solve because in PS
The problem of middle addition inorganic filler influences PS composite properties.
The present invention is achieved by the following technical solutions：
A kind of fire-retardant scratch-resistant PS composite materials, are made of the component of following parts by weight：
Wherein ultrafine aluminium hydroxide passes through coupling agent treatment.
The ultrafine aluminium hydroxide is uniform particle sizes, and particle diameter is 0.6-1.5 μm of aluminium hydroxide.
The antioxidant is three (2,4- di-t-butyl) phenyl-phosphites, four [β-(3,5- di-tert-butyl-hydroxy phenyls)
Propionic acid] pentaerythritol ester or 1,3,5- trimethyls -2,4, one kind or more in 6- (3,5- di-t-butyl -4- hydroxyphenylmethyls) benzene
Kind.
The lubricant is the combination of one or both of calcium stearate, stearic acid sodium.
The coupling agent is one kind in Silane coupling agent KH550 or KH570.
The mass ratio of the aluminium hydroxide and coupling agent is 60-80: 4-8.
The beneficial effects of the invention are as follows：
The ultrafine aluminium hydroxide that the technical program provides can be better dispersed in PS after silane coupling agent is handled, this
Be conducive to keep the physical property of PS composite materials.
Ultrafine aluminium hydroxide in the technical program, which is heated, is decomposed into aluminium oxide, on the one hand it can form surface carbonation layer,
The entrance of heat and oxygen is prevented, improves the flame retardant effect of composite material, on the other hand it can also improve the hard of PS composite materials
Degree, improves the scraping and wiping resistance performance of material.
