Description
Technical field
The application belongs to plastic alloy material field, relates in particular to a kind of PC plastic alloy.
Background technology
Merlon (being called for short PC) is the high molecular polymer that contains carbonate group in strand,Can be divided into the polytypes such as aliphatic, aromatic series, aliphatic-aromatic according to the structure of ester group.Wherein because the mechanical performance of aliphatic and aliphatic-aromatic Merlon is lower, thus limitMake its application aspect engineering plastics. Only there is at present aromatic copolycarbonate to obtain industryChange and produce. Due to the particularity on polycarbonate structure, now become in five large-engineering plastics and increasedLong fastest general engineering plastic.
PC is the amorphous polymer of almost colourless glassy state, has well optical. PCHigh molecular weight resin has very high toughness, and cantilever beam notched Izod impact strength is 600～900J/m,The heat distortion temperature of not filling the trade mark is approximately 130 DEG C, and glass fibre can make this after strengtheningNumerical value increases by 10 DEG C. More than the bending modulus of PC can reach 2400MPa, resin can be processed intoLarge rigid articles. During lower than 100 DEG C, the creep rate under load is very low. PC hydrolysisProperty is poor, can not be used for repeating to stand the goods of high steam.
Three large applications of PC engineering plastics be glazing, auto industry and electronics,Electrical equipment industry, secondly also has the offices such as industrial machinery part, CD, packaging, computer to establishStandby, medical treatment and health care, film, leisure and protective equipment etc. PC can be used as door glass,PC laminate is widely used in the protective window of bank, embassy, the house of detention and public place, forAircraft cabin cover, lighting apparatus, industry security plate washer and bulletproof glass. PC plate can do various marksBoard, refers to as petrol pump dial plate, fascia, warehouse and outdoor business label, point type slideShow device, PC resin is for automobile lighting system, and instrument panel system and interior trim system, be used asFront lamp cover, plate washer before and after band reinforcement automobile, reflective frame, Door frame, action bars sheath,Spoiler, PC are employed as terminal box, socket, plug and sleeve pipe, pad, TV and turnChanging device, the connector of communication cable under telephone line support, switch box, telephone exchange, joinsElectroplax element, relay1 case, PC can make low load part, for household electrical appliance motor,Vacuum cleaner, the handle of device for washing one's hair, coffee machine, bread baker, power tool, various teethWheel, worm gear, axle sleeve, lead shelf in rule, refrigerator. PC is the desirable material of disc storage mediumMaterial. PC bottle (container) is transparent, lightweight, impact resilience is good, resistance to certain high temperature and corrosionSolution washing, as recoverable bottle (container). PC and PC alloy can do computer rack,Shell and subsidiary engine, printer part. The sterilization of modification PC resistant to high energy radiation, resistance to boiling and bakingSterilization, the sample utensil that can be used for taking a blood sample, blood oxygenators, surgical operating instrument, kidney dialyzerDeng, PC can make the helmet and safety cap, protective face mask, sunglasses and motion cover glass. PC filmBe widely used in printing chart, medical packaging, membrane type commutator.
