Description
Technical field
The present invention relates to technical field of polymer materials, specifically a kind of low gloss anti-impact weather resistant PC matrix material.
Background technology
Polycarbonate (PC), as excellent combination property, purposes important engineering plastics kind very widely, is widely used in automobile, electric, material of construction, mechanical component, business automation equipment, packing business, sports equipment, medical treatment, health care, the field such as CD and household supplies.But PC is in production, storage and use, due to the comprehensive action by internal and external factor, its performance will degenerate gradually and affect use, catabiosis that Here it is, in addition, also there is poor processability, easily stress cracking in pure PC material, resistance to breach is more responsive, and wear resistance is not good enough, the deficiency of the aspects such as chemical proofing difference, simultaneously in some application scenario, as automobile plastic inside gadget, PC goods usually require that outward appearance has low gloss.Therefore, as required to PC carry out low gloss, shock resistance, the aspect such as weather-proof modification be very important, to improve its performance and broadened application scope etc.
Summary of the invention
The object of the present invention is to provide a kind of low gloss anti-impact weather resistant PC matrix material.
The technical solution adopted for the present invention to solve the technical problems is: low gloss anti-impact weather resistant PC matrix material, and its component by mass percent proportioning is: PC resin 75% ~ 90%, anti-impact modifier 5% ~ 10%, matting agent 1% ~ 3%, photostabilizer 1% ~ 3%, expanding material 2% ~ 4%, oxidation inhibitor 0.1% ~ 0.5%, lubricant 0.1% ~ 1.5%.
Described PC resin is bisphenol A-type aromatic copolycarbonate, and weight-average molecular weight is 20000 ~ 30000g/mol.
Described anti-impact modifier is that the acrylic ester impact-resisting with nucleocapsid structure hits properties-correcting agent ACR or methacrylate butadi ene styrene copolymer MBS.
Described matting agent is organic polymer matting agent, preferred crosslinking butadiene-acrylonitrile polymer or cross-linking type SAN.
Described photostabilizer is the compound of hindered amines high molecular photostabilizer GW-944Z and GW-622 of mass ratio 1:1.
Described expanding material is polymethylmethacrylate grafted maleic anhydride (PMMA-g-MAH).
Described oxidation inhibitor is the Hinered phenols antioxidant 1076 of mass ratio 1:1 and the compound of phosphite ester kind antioxidant 168.
Described lubricant is pentaerythritol stearate (PETS).
The preparation method of above-mentioned low gloss anti-impact weather resistant PC matrix material is: take each component by weight ratio, and add respectively in high-speed mixing and stir 5 ~ 30 minutes together, make fully mixing and dispersed after, discharging adds in twin screw extruder, extrude through melting mixing at 250 DEG C ~ 290 DEG C, cooling granulation, get product.
The invention has the beneficial effects as follows, compared with prior art, the PC matrix material that the present invention obtains, not only there is low gloss, outward appearance matte effect is good, but also there is the advantages such as anti-impact efficiency is high, good weatherability, flexibility of operation are strong, maintain PC excellent mechanical performance, chemical property and electric property simultaneously, the fields such as automobile, electronic apparatus, machinery, chemical industry, medical treatment, packaging, sports apparatus, office and household supplies can be widely used in.
