Abstract
The invention relates to master batches. The master batches are mainly used for enhancing PP (polypropylene), PE (polyethylene), ABS (acrylonitrile-butadiene-styrene), PA (polyamide) injection products and the like and have very good effects on the strength of PP, PE, PVC (polyvinyl chloride) tubular products and panels. The master batches comprise 40-60 parts of starch, 10-20 parts of polyvinyl chloride, 1-5 parts of compatilizer, 1-5 parts of lubricant, 1-5 parts of mica and 1-5 parts of carbon dioxide. A preparation method of master batches comprises the following steps: grafting maleic anhydride on polyethylene so as to obtain polyethylene grafted maleic anhydride, and afterwards, using the polyethylene grafted maleic anhydride for filling and modifying a polymer together with talcum powder, the mica, the titanium dioxide and the like, thus obtaining the master batches. The elasticity modulus, heat resistance, strength, toughness and the like of the master batches are obviously improved.
Description
Technical field
The present invention relates to a kind of master batch, relate in particular to a kind of master batch of increased functionality.
Background technology
Along with expanding economy, PP, PE, ABS, developing rapidly of the injecting products such as PA, high-quality, high performance injecting products will be needed on market, in order to strengthen the intensity of injecting products, Young's modulus, during the performances such as thermotolerance, all generally to add master batch in injecting products now, master batch is to for strengthening PP, PE, ABS, the injecting products such as PA and PP, PE, pvc pipe material, timber intensity has good effect, and master batch refers to the enriched material of various additives for plasticss, main component is polyethylene wax, carrier tree coupling agent, filler etc., the toughness of present some master batch, insufficient strength is high, the unfavorable factors such as dimensional stability is poor have limited its range of application, such master batch can not meet high-performance sometimes, the need of high quality injecting products, can not meet the needs in market simultaneously, so need performance function master batch to make up these defects.
Summary of the invention
Technical problem to be solved by this invention is: a kind of master batch is provided, and described master batch has the performances such as intensity is high, toughening effect good, wear-resisting.
For addressing the above problem, technical scheme of the present invention is a kind of master batch, and described master batch consists of the following composition:
Further, described starch is industrial starch, is tapioca (flour) and potato starch 1:3 mixture.
The polyethylene 1:1 mixture of the polyethylene that further, described polyethylene is low polymerization degree and high-polymerization degree.
Further, described compatilizer is maleic anhydride.
Further, described lubricant is talcum powder.
Further, the preparation method of described master batch is as follows:
1) by starch dry 30 minutes～60 minutes under field conditions (factors), filter out detailed catalogue subsequently and be less than 200 object starch;
2) polyethylene and maleic anhydride are sent in twin screw extruder in the ratio of 10～15:1, then stirred 10～15 minutes, melting graft reaction occurs therein, after cooling 10～15 minutes, can obtain finished product maleic anhydride grafted polyethylene;
3) the finished product maleic anhydride grafted polyethylene obtaining and starch, mica, titanium dioxide are sent into high-speed mixer high speed stirring 15～30 minutes;
4) material after stirring is sent in twin screw extruder, through twin screw extruder, extruded, after granulation, can obtain finished product master batch.
Compared with prior art, the present invention passes through maleic anhydride graft on polyethylene, obtain Research of Grafting Malaic Anhydride Onto Polyethylene, subsequently Research of Grafting Malaic Anhydride Onto Polyethylene is carried out to the filling-modified master batch that obtains to polymkeric substance together with talcum powder, mica, titanium dioxide etc., the performances such as the Young's modulus of this master batch, thermotolerance, intensity, toughness all have significantly improved.
