Description
Technical field
The invention belongs to polymeric material field, be specifically related to a kind of modified special material for the manufacture of conductive turnover box and preparation method thereof.
Technical background
Plastic cement Turnover Box is running case, the box for material circulation produced with plastic cement, and plastic cement Turnover Box belongs to packaging and circulation material type.Mostly existing plastic cement Turnover Box is on the market to select the HDPE(low-pressure high-density polyethylene with high impact) and PP (polypropylene) for raw material disposable injection molded.China produces, the time of application plastic cement Turnover Box is not long, but obtains in the recent decade and develop extremely rapidly.Almost instead of traditional wooden Turnover Box completely now, make place in food and logistics etc. and be all widely used.Why plastic box promptly can replace traditional wooden Turnover Box, except timber resources is nervous, outside supply bottleneck, plastic cement Turnover Box superior performance, load-bearing better, convenient formation, cheap, be major reason.The specification of Turnover Box is also more various, environment friendly and pollution-free, generally can reach the strict demand of outlet and dress food grade.Because plastic cement Turnover Box material is light, intensity is high, nontoxic pollution-free, waterproof and dampproof, acid-alkali-corrosive-resisting, resistance to greasy dirt, various colors, having good environmental-protecting performance and suitability for secondary processing, is a kind of novel environment friendly wrapping material of generally adopting of many advanced countries in the world.At present, (case lid had is supporting separately making, the box for material circulation product that generally all general a few money is of the same type for some common on the market plastic cement Turnover Boxes are also supporting case lid.Having plenty of the case lid for designing with a case, is all link with casing or connected as one by other auxiliary accessories and casing).Also some plastic cement Turnover Box is designed to collapsible style, also reduces logistics cost back and forth when empty van while of can reducing storage volume.
Plastic cement Turnover Box is different with most of Plastic Packaging Materials, general Plastic Packaging Materials polyphyly single use, and after taking out product, namely wrapping material complete its historic mission, make waste external.Plastic cement Turnover Box then often will reclaim after usage to be reused repeatedly, and therefore plastic cement Turnover Box is except structurally design concept, also will consider selecting of its material according to purposes, such as conductive turnover box.Except should be taken into account that it in use; to have outside good protection and storing function to the article of institute's splendid attire; the special purposes considering that its needs conduct electricity is needed toward contact; need in special working conditions according to these Turnover Boxes; modification is carried out to it, so just can produce suitable Turnover Box.And Turnover Box material on the market or poor electric conductivity, or the cost of material is too high, does not meet economic benefit.Therefore be badly in need of providing the Turnover Box material that a kind of cost is not high, have excellent conductive performance simultaneously.
Summary of the invention
The present invention seeks to overcome the deficiencies in the prior art, a kind of modified special material for the manufacture of conductive turnover box with low cost and preparation method thereof is provided.
The object of the invention is to be achieved through the following technical solutions:
A kind of modified special material for the manufacture of conductive turnover box, it is made up according to weight of following raw materials according: HDPE40-50 part, polyisoprene 4-8 part, Tristearoylglycerol 8-12 part, polystyrene 10-18 part, PE-g-ST3-7 part, high glue powder 4-8 part, glass fibre 8-10 part, butyl glycol ether 4-8 part, tetraisopropoxy titanium 4-9 part, aluminium sesquioxide 4-8 part, activated Calcium carbonate 3-7 part, Vltra tears 8-12 part, silicone powder 5-10 part, stablizer 4-8 part, coupling agent 2-6 part, toughner 4-8 part, TriMethylolPropane(TMP) 3-7 part, polyethylene terephthalate 5-8 part and clorafin 5-10 part.Described stablizer is organotin stabilizer, Theil indices >=20%.Described coupling agent is silane coupling agent KU-550.Described toughner is that maleic anhydride meets POE.
For the manufacture of a preparation method for the modified special material of conductive turnover box, the preparation process of the method is as follows: added together in high mixer by above-mentioned raw materials and carry out moderate-speed mixer mixing, obtain Preblend; Preblend is put into twin screw extruder heating and melting extrusion plasticizing, obtain work in-process, its working conditions is: temperature is 220 ~ 230 DEG C, and screw speed is 420r/min; Finally work in-process are carried out tie rod, cooling, drying, granulation, obtain PP Pipe Compound, wherein in process of cooling, the temperature of water coolant remains on 35 ~ 45 DEG C.
Beneficial effect: the present invention carries out modification by adding adjuvant component, do not affect other materials performance and do not increase cost prerequisite under, improve the conductivity of product to large extent, the modifying material good toughness prepared, shock-resistant, be easy to the Turnover Box that processing electrically conductive can be good, improve added value of product.Adopt method of the present invention, not only can effectively prepare qualified finished product, and operating process is very simple, is convenient to scale operation.
