Abstract
The invention discloses a melting graft modified K-resin and a preparation method thereof. The melting graft modified K-resin comprises the following ingredients in parts by weight: 100 parts of K-resin, 1-5 parts of modifier, 1-5 parts of styrene and 0.1-0.5% of an initiator. The K-resin is modified, so that the solubility of the modified K-resin with other polymers is improved; and after the modified K-resin is mixed with other polymers such as GPPA, SAN (Styrene) and HIPS (High Impact Polystyrene), alloy materials with impact resistance and high light transmittance can be prepared; the characteristic that the transparent resin in market cannot have both the transparence and impact resistance is overcome, and therefore the melting graft modified K-resin has good market application prospects.
Description
Technical field
The present invention relates to material science, especially a kind of macromolecular material and preparation method thereof.
Background technology
K glue is vinylbenzene and butadiene block copolymer, its main characteristic is to have high transparent and good little, the strong coloring force of shock resistance, density concurrently, processing characteristics is excellent, nontoxicity, be widely used in refrigerator manufacturing, electrical instrumentation dish, with fields such as other material (such as GPPS, SAN, SMA, PP, HIPS etc.) blending modifications.But, K glue polarity relatively poor with other polymer blending be that consistency is poor, affect the product mechanical property.Therefore, chemical modification improves K glue and other polymer phase capacitive is extremely important by K glue is carried out.The method of consistency is that polymkeric substance is carried out graft modification when raising polymer polarity commonly used and then raising and other polymer blending, but the present research that K glue is carried out graft modification is carried out Modification by Melt Grafting to K glue and be yet there are no report also than seldom.
Summary of the invention
The objective of the invention is: a kind of Modification by Melt Grafting K glue and preparation method thereof is provided, and its percentage of grafting is high, with low cost and the feature of environmental protection is good, to overcome the deficiencies in the prior art.
The present invention is achieved in that Modification by Melt Grafting K glue, calculates by weight, comprises 100 parts of K glue, 1～5 part of properties-correcting agent, 1～5 part of vinylbenzene and the initiator that accounts for total mass 0.1～0.5%.。
Described properties-correcting agent is one or more the combination in vinyl acetate, glycidyl methacrylate, maleic anhydride, vinyl acetate between to for plastic-copolymer-maleic anhydride or the styrene-maleic anhydride copolymer.
Described vinylbenzene is altogether monomer of grafting.
Described initiator is isopropyl benzene hydroperoxide, tertbutyl peroxide, dibenzoyl peroxide, di-isopropyl peroxydicarbonate, di-cyclohexylperoxy dicarbonate or 2; 5-dimethyl-2, the combination of one or more among the 5-(2-ethyl hexyl acyl group peroxide).
The preparation method of Modification by Melt Grafting K glue by above-mentioned weight fraction, gets K glue, properties-correcting agent, vinylbenzene and initiator, and they are mixed; The material that mixes joined in the twin screw extruder melt extrude, obtain finished product after the granulation.
One district's temperature of twin screw extruder is that extrusion temperature is 210～220 ℃, and the forcing machine rotating speed is 275～300rpm.
Owing to adopted above-mentioned technical scheme, compared with prior art, the present invention carries out modification to K glue, not only can improve K glue after the modification and the consistency between other polymkeric substance, and will be through after other polymer blendings such as Modified K glue and GPPS, SAN, HIPS, can prepare the alloy material shock-resistant, that transmittance is high, can overcome the transparency and the shock-resistant characteristics that can not have both of transparent resin general on the market, have good market application foreground.Material source of the present invention is extensive, is easy to obtain, and result of use is good.
