Description

Heat-resisting HIPS/PPS matrix material of a kind of halogen-free flameproof and preparation method thereof
Technical field
The present invention relates to the Modification of High-impact Polystyrene technical field, be specifically related to heat-resisting HIPS/PPS matrix material of a kind of halogen-free flameproof and preparation method thereof.
Background technology
Polystyrene (PS) is one of five large general-purpose plastics, and it has, and formability is good, matter is hard, transparent, electrical insulating property, agent of low hygroscopicity and the advantage such as cheap.Generate high-impact polystyrene resin (HIPS) mixes a small amount of elastomerics in PS after, it has overcome the crisp shortcoming of polystyrene, thereby is widely used in the industries such as electronics, automobile, household electrical appliances, instrument, daily necessities, toy.But HIPS burns easily, and weathering resistance is poor, and easily initiation fire two causes unnecessary financial loss, even loss of life and personal injury.Therefore, all the requirements such as fire-retardant, weather-proof have been proposed high-impact polystyrene resin in many Application Areass.
When guaranteeing fire safety, along with the International Environmental Protection legislation is increasingly strict, people more and more pay close attention to some fire retardants to the harmful effect of environment and human body generation.The RoHS of the European Union environmental protection instruction of putting into effect in 2003 is listed polybromodiphenyl ether in electronic and electrical equipment and is limited the use of the objectionable impurities list, from 1 day July in 2006, forbids using Polybrominated biphenyl (PBB) and Poly Brominated Diphenyl Ethers (PBDE) in electronic electric equipment.The numerous famous enterprise of the U.S., Europe, Japan---Microsoft, DELL, Philip, THOMSON, Sony, Panasonics etc. are all take European environmental protection instruction as limiting the relevant criterion that related substance uses according to having formulated.
There have been the achievement in research of halogen-free flameproof polystyrene correlation technique in more international major companies such as Korea S Samsung, LG-DOW company, but non-environmental-protection flame-retardant PS is high more than 50% for its cost ratio tradition, and there is no at home the ripe the techniques of mass production of grasping this product of producer at present.
