Description
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.
Summary of the invention

The heat-resisting HIPS/PPS composite manufacture of above-mentioned halogen-free flameproof method may further comprise the steps:
(1) with polyphenylene sulfide, high-impact polystyrene resin 70～90 ℃ of drying 4～8h in loft drier respectively;
(2) take by weighing dry good polyphenylene sulfide, high-impact polystyrene resin, toughner, halogen-free flame retardants, retardant synergist and other auxiliary agent by the weight proportion of setting;
(3) raw material in the step (2) is put into be dry mixed 4～5min in the super mixer;
(4) mixed raw material in the step (3) is put into forcing machine, through melting, granulation.
Complete processing is as follows in the step (4): twin screw extruder one district temperature 80-100 ℃, and two district temperature 150-170 ℃, three district temperature 210-230 ℃, four district temperature 210-230 ℃, five district temperature 210-230 ℃, six district temperature 210-230 ℃, seven district temperature 200-220 ℃, eight district temperature 200-220 ℃, nine district temperature 200-220 ℃, ten district temperature 210-230 ℃, head temperature 200-220 ℃, residence time 2-3min, pressure are 10-20Mpa.
Owing to taked technique scheme, matrix material of the present invention has been obtained following beneficial effect: 1) the present invention adopts the organonitrogen series composite flame retardant, cooperates inorganic fire-retarded synergistic agent to obtain excellent flame retardant effect, and flame retardant properties reaches the V-0 level; 2) prepared matrix material has resistance to elevated temperatures, and heat-drawn wire is higher than 170 ℃; 3) good fluidity, melting index reaches 48g/10min; 4) excellent insulation performance.Simultaneously, preparation method proposed by the invention has the advantage that technique is simple, easy to operate, cost is low.
