Abstract

The invention relates to a PC thin film material which is prepared from PC, cobalt aluminate, magnesium hydroxide, stannous octoate, a silane coupling agent, methyl acrylate, talcum powder, antimonous oxide, polybutylene terephthalate, benzoyl peroxide, potassium persulfate, hydroxypropyl methyl cellulose, p-tert-octyl phenol, white carbon black, barium stearate, polymethylphenyl siloxane fluid, graphite powder, molybdenum disulfide, Fischer-Tropsch wax and sodium alkyl benzene sulfonate.The PC thin film material is good in film forming performance, environmentally friendly, flame-retardant, low in smoke and toxin, high in glow wire ignition temperature (GWIT is larger than or equal to 900 DEG C), high in glow wire combustion temperature (GWFI is larger than or equal to 960 DEG C) and high in oxygen index (LOI is larger than or equal to 44), suitable for the electronic and electric appliance field such as keyboard insulation, television/displayer insulation and computer main board insulation.

Description

technical field [0001] The invention relates to polymer materials, in particular to a PC thin film material and a preparation method thereof. Background technique [0002] Polycarbonate (Polycarbonate, referred to as PC) is a polycarbonate composite material of an amorphous thermoplastic engineering plastic with excellent performance. It has outstanding impact resistance, good creep resistance and dimensional stability, heat resistance, low water absorption, It is non-toxic and has excellent dielectric properties. It is the only product with good transparency among the five major engineering plastics, and it is also the fastest growing general engineering plastic in recent years. At present, it is widely used in automobiles, electronics, construction, office equipment, packaging, sports equipment, medical care and other fields. With the continuous deepening of modification research, it is rapidly expanding to high-tech fields such as aerospace, computers, and optical discs. ...
