Description
Technical field
The present invention relates to technical field of polymer materials, relate in particular to a kind of halogen-free and flame-retardant polycarbonate (PC) material and preparation method.This halogen-free flame retardant PC material can be applied to electronic electric equipment built-in electrical insulation film article.
Background technology
Polycarbonate; Be called for short PC; For containing the general name of
group polymkeric substance on the main chain; Realize industriallization in nineteen fifty-nine, development thereafter rapidly.It is the thermoplastic engineering plastic of one type of high comprehensive performance; In thermoplastics, have the high impulse strength and the good transparency; Can in awide temperature range, keep very high physical strength, good electrical properties, higher dimensional stability; Simultaneously easy to process, be widely used in fields such as mechanical means, construction work, communications and transportation, instrument and electric lighting, become the second largest engineering plastics that output is only second to nylon at present.Contain phenyl ring on the PC main chain, can be condensed into the fragrant charcoal during burning, charring rate is higher, has self-extinguishing; Flame retardant rating is UL94V-2, but flammable, and hot melts drips during burning; Near causing material catches fire, so be difficult to satisfy the requirement of some field to flame retardant properties, therefore PC is carried out flame-retardant modified [Innes J; Et al.Plastic Additive Compound, 2006,8 (1): 26].
What China more often adopted at present is halogenated flame retardants such as decabromodiphynly oxide, tetrabromo-bisphenol, brominated carbonic ether oligopolymer; The often shock strength of the big and heavy damage PC of consumption and electrical property etc.; And have problem of environmental pollution, industrially developed country such as West Europe, North America and Japan or area have have successively enacted and enforced the instruction that bans use of halogenated flame retardant; Silicoorganic compound are fire retardant [LuSY, Hamerton I.Progress in Polymer Science, 2002 of one type efficient, nontoxic, low cigarette, environment friendly; 27 (8): 1661]; But complex process costs an arm and a leg, and is difficult to popularize; And fire retardation is not enough when using separately, needs and the compound use of other fire retardant; With 3M company is that the sulfonic fluoropolymer salt fire retardant (such as 2025) of representative also is the one type of efficient flame-retarding agent that is applicable to that PC is fire-retardant that grew up in recent years; But it has limited its application on film article because dispersiveness and flame retarding efficiency (being difficult to reach the V-0 of the following thickness of 0.8mm) are not enough; The decomposition temperature of organic phosphine flame retardant own is lower, and addition is generally 5%-15%, and is big to the mechanical property infringement of PC, be not suitable in PC, using, so the halogen-free flameproof problem of PC solves than exigence.
Summary of the invention
The object of the invention is exactly environment to be existed defectives such as pollution and/or flame retardant properties deficiency to existing fire retardation PC material, and a kind of preparation that is easy to is provided, and has halogen-free flame retardant PC material of better mechanical property and high flame retardant and preparation method thereof.This fire retardation PC material can reach 0.38mm UL94V-0 level.
The object of the invention can be realized through following technical scheme.
A kind of halogen-free and flame-retardant polycarbonate material is characterized in that being processed by following materials of weight proportions:

Said micro encapsulation red phosphorus combustion inhibitor can be substituted by the masterbatch that microcapsule red phosphorus powder and PC or vector resin are formed; What the optional free Bluestar (Chengdu) New Material Co., Ltd. of this masterbatch produced is the red phosphorus flame-retardant masterbatch RPM240 or the RPM250 product of carrier with PC; Wherein, " 2 " expression PC carrier, the weight percent content of " 40 " or " 50 " expression microcapsule red phosphorus powder; And the add-on of PC and vector resin counts the content of raw material polycarbonate and raw material carrier resin respectively in the masterbatch.
The resin that said vector resin is selected and polycarbonate has certain consistency is such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT) or SAN (SAN) etc.
Said toughner is the anti-impact modifier with nucleocapsid structure; Like (styrene butadiene-methacrylic ester ter-polymers or styrene-propene acid butyl ester-methacrylic ester ter-polymers), have a terpolymer of epoxide group; Like (ethylene-acrylate-epoxy glycidyl ester copolymer), perhaps graft rubber is like (grafting terpolymer EP rubber) etc.
Said fire retarding synergist is selected polytetrafluoroethylene (PTFE).
Said lubricant is selected ethylene bis stearamide (EBS) or pentaerythritol stearate (PETS) etc.
Said stablizer is for to form by the auxiliary antioxidant of Hinered phenols primary antioxidant and phosphorous acid esters is composite, and the weight ratio of primary antioxidant and auxiliary antioxidant is 1: 2～2: 1.
Said hindered phenol anti-oxidants comprises: antioxidant 1010 or antioxidant CA etc.
Said phosphorous acid esters inhibitor comprises: oxidation inhibitor 168 or trisnonyl phenyl phosphite etc.
Halogen-free and flame-retardant polycarbonate preparation methods of the present invention is undertaken by following process step:
Step 1: polycarbonate, micro encapsulation red phosphorus combustion inhibitor, vector resin placed 100～120 ℃ dry 12～20 hours of baking oven;
Step 2: take by weighing each raw material by above-mentioned weight percent;
Step 3: each raw material that will take by weighing mixed 2～5 minutes in rotating speed is the blender of 800rpm～3000rpm;
Step 4: the material that mixes is got product through the twin screw extruder extruding pelletization; The processing condition of granulation are: 220～260 ℃ of temperature, 100～200 rev/mins of screw speeds.
Useful technique effect of the present invention shows:
1, the present invention adopt micro encapsulation red phosphorus or the masterbatch formed with vector resin as fire retardant, cooperate fire retarding synergist simultaneously, thereby make product of the present invention reach the very flame retardant resistance of high request of 0.38mm UL94 V-0 level;
2, the present invention adopts micro encapsulation red phosphorus also to guarantee the stability of red phosphorus powder in the course of processing;
3, the present invention has significantly improved the low drawback of red phosphorus flame-retardant material impact intensity through adding toughner;
