Description
Technical field
The present invention relates to a kind of master batch, specifically the wear-resisting scratch master batch of a kind of PC.
Background technology
Polycarbonate (PC) has excellent shock-resistance and the transparency, excellent mechanical property and electrical insulating property, use temperature scope wide (-100 DEG C ~ 130 DEG C), dimensional stability is high, creep resistant is good, is a kind ofly to integrate the representative of firm, hard, tough typical plastics.Because these advantages make PC be widely used in numerous field such as electronic apparatus, office appliance, precision machinery, medical treatment, labour protection, household supplies and automobile.But due to PC wear-resistant scratch-resistant can poor, hardness is low, thus greatly limit its range of application.Good wear-resisting scratch resistance effect can be obtained by carrying out wear-resisting scratch modification to PC, but directly add wear-resisting scratch agent at PC, because addition is little, dispersion may be caused uneven and affect quality.Master batch is attached to super quantity auxiliary agent a kind of condensation product made in resin, has easy to use, good dispersity, can avoid environmental pollution again, be conducive to cleaner production etc., is one of main form of current plastic cement sector application additive modification.Therefore, research and develop a kind of PC wear-resisting scratch master batch, to PC modification, there is good suitability for industrialized production and application prospect thereof.
Summary of the invention
The object of the present invention is to provide that a kind of concentration is high, good dispersity and the wear-resisting scratch master batch of PC easy to use.
The technical solution adopted for the present invention to solve the technical problems is: the wear-resisting scratch master batch of PC, and its component by mass percent proportioning is: vector resin 15% ~ 30%, gas phase nano white carbon black 30% ~ 50%, wear-resisting scratch agent 20% ~ 30%, slipping agent 3% ~ 8%, coupling agent 0.5% ~ 3%, dispersion agent 2% ~ 4%.
Described vector resin is bisphenol A-type aromatic copolycarbonate (PC).
Described scratch resistance liniment is the ultra-high molecular weight siloxane polymer with active group, and its active group is one or more in hydroxyl, epoxy group(ing), carboxyl, acid anhydrides.
Described slipping agent is amine hydroxybenzene (ER) or erucicamide (VRX).
Described coupling agent is titanate coupling agent or aluminium titanium composite coupler.
Described dispersion agent is the one in EVA wax, PETS, TAS-2A.
The preparation method of above-mentioned PC wear-resisting scratch master batch is: take each component by weight ratio, add respectively in high-speed mixing, together and stir 5 ~ 25 minutes, make fully mixing and dispersed after, discharging adds in twin screw extruder, extrude through melting mixing at 240 DEG C ~ 260 DEG C, cooling granulation, and dry rear packaging, get product.
The invention has the beneficial effects as follows, compared with prior art, when the wear-resisting scratch master batch of the PC that the present invention obtains is applied to PC production, there is good dispersity, the feature such as easy to use, and to PC, there is good wear-resisting scratch modified effect, and its intensity, rigidity and thermotolerance can also be improved, be conducive to improving processing fluidity and conveniently realizing suitability for industrialized production etc., thus there is good result of use.
