Description
Technical field
The present invention relates to a kind of master batch, specifically the toughness reinforcing transparent master batch of a kind of PC light diffusion.
Background technology
Polycarbonate (PC) as one of five large-engineering plastics is a kind of amorphous, odorless, tasteless, nontoxic, transparent thermoplastic polymer, it is the plastics variety uniquely with good transparency, and there is good physical strength, resistance toheat and resistance to electric over-all properties, also there is impact strength simultaneously high, creep properties is little, product size is stablized, easy enhancing, non-toxic sanitary, can be painted, cost performance is high, can chemically modified and the advantage such as physically modified potentiality are large, be widely used in glazing, automotive industry, electronic apparatus, component of machine, CD, packaging, the office equipments such as computer, medical treatment and health care, film, the fields such as leisure and protective equipment.But PC also exists some shortcomings, as lower in: fatigue resistance, to notch sensitive, easily produce stress cracking, poor solvent resistance, cost is more high, and along with market competition, to PC in every respect performance it is also proposed requirements at the higher level, as light diffusion effect, high tenacity, the transparency etc.Therefore, for expanding the range of application of PC and improving its performance, usually modification need be carried out to PC.But PC modification is generally add various types of filler, auxiliary agent in PC production process, but due to these fillers, auxiliary agent great majority be powder, direct interpolation not only can cause that technique is loaded down with trivial details, production efficiency is low, and is unfavorable for cleaner production and industrial automation etc.Master batch is attached to super quantity auxiliary agent or filler 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 the toughness reinforcing transparent master batch of a kind of PC light diffusion to be applied to PC modification there is good application prospect.
Summary of the invention
A kind of PC light easy to use, that good dispersity, the transparency are high is the object of the present invention is to provide to spread toughness reinforcing transparent master batch.
The technical solution adopted for the present invention to solve the technical problems is: the toughness reinforcing transparent master batch of a kind of PC light diffusion, its component by mass percent proportioning is: vector resin 15% ~ 40%, inorganic mineral powder 50% ~ 70%, light diffusing agent 10% ~ 15%, coupling agent 0.5% ~ 3%, dispersion agent 2% ~ 5%.
Described vector resin is bisphenol A-type aromatic copolycarbonate (PC).
Described inorganic mineral powder is tremolite compound acicular powder, and its chemical constitution is Ca

2, density is 2.68 ~ 2.72g/cm
3, oil-absorption(number) is 30 ~ 36mL/100g, and it has strengthening and toughening function, and the transparency is good.
Described light diffusing agent is cladded type organosilicon light diffusing agent or cladded type esters of acrylic acid light diffusing agent.
Described coupling agent is aluminium titanium composite coupler.
Described dispersion agent is the one in EVA wax, OP wax, PETS.
The preparation method of the above-mentioned toughness reinforcing transparent master batch of a kind of PC light diffusion is: take each component by weight ratio, add respectively in high-speed mixing, stir 3 ~ 15 minutes, make fully mixing and dispersed after, discharging adds in twin screw extruder, extrude through melting mixing at 245 DEG C ~ 260 DEG C, cooling granulation, and dry after packaging, get product.
The invention has the beneficial effects as follows, compared with prior art, when the toughness reinforcing transparent master batch of a kind of PC light diffusion that the present invention obtains is applied to PC production, there is the features such as good dispersity, light diffusing be strong and easy to use, and to PC, there is good strengthening and toughening effect, and transparent height, flow processability is good, comprehensive mechanical property is excellent, adds and have good result of use in PC membrane product.
