Description
Technical field
The present invention relates to be a kind of overall plastic microcosmic stratified composite and preparation method thereof, be applied in the hose packing of water-emulsion-based paste substance.
Background technology
At present, a large amount of traditional lipid, organic solvent hose packing materials that use on the market all belong to multilayer materials on the macroscopic view as plastic-aluminum combined, overall plastic multi-layer co-extruded matrix material etc.These macroscopical multilayer materials have not only expended a large amount of energy in short supply and bauxite resource, and have caused the pollution of ecotope on material is selected.Even reclaim, processing cost is quite expensive.More numerous and diverse at aspects such as complete processing, processing unitss, generally must use many processing unitss ability processing and fabricatings, because complicated its price of the formation of material and complete processing is also higher.
Summary of the invention
The technical problem of solution required for the present invention is to satisfy the requirement of water-emulsion-based paste oil substances hose packing, overcomes the defective of a few class materials in the prior art (as aluminium plastic composite material, multi-layer co-extruded material) again.For example: material cost height, complete processing complexity, product use the back to discard multiple deficiencies such as the processing cost costliness of packing tube, environmental pollution.
The present invention is achieved in that a kind of overall plastic microcosmic stratified composite, it is characterized in that its material and proportioning (weight ratio) are: polyvinyl resin 75～85%, aromatic nylon 5～16%, polynite 3～8%, grafts 5～13%, described polyvinyl resin is by high density polyethylene(HDPE), new LDPE (film grade), linear low density polyethylene is formed, three kinds of material ratios of described polyvinyl resin are: high density polyethylene(HDPE): new LDPE (film grade): linear low density polyethylene=2: 2: 1, aromatic nylon is at nylon 6, nylon 66, select a kind of in the nylon 1010, polynite is at NB901, select a kind ofly among the NB908, grafts is at ethene---acetate ethylene copolymer, select a kind of in the poly maleic anhydride grafts.Described overall plastic its material of microcosmic stratified composite and weight proportion are: polyvinyl resin 75%, aromatic nylon 16%, polynite 3%, grafts 6%.Described overall plastic its material of microcosmic stratified composite and weight proportion are: polyvinyl resin 85%, aromatic nylon 5%, polynite 3%, grafts 7%.As required, can add in the material various Masterbatchs, also can add the photosensitized oxidation agent, also can add modified composite material.Described modification matrix material comprises polyvinyl resin, filler, lubricant, coupling agent, filler is chosen a kind of in lime carbonate, talcum powder, mica powder, lubricant is chosen a kind of in paraffin or whiteruss hydro carbons lubricant, stearic acid fat acids lubricant, Zinic stearas or calcium stearate metallic soap series lubricant agent, polyethylene wax, EBS lubricant, and coupling agent is chosen a kind of in silane coupling agent, titanate coupling agent, aluminate coupling agent.A kind of preparation method of overall plastic microcosmic stratified composite is characterized in that: each the material elder generation mixing granulation with described matrix material, and use compressing tablet of extrusion calendaring machine to become a useful person then, form microcosmic layered composite structure sheet material.
The advantage of a kind of overall plastic microcosmic stratified composite of the present invention is: at first; employing has multiple macromolecular material and various Masterbatch or (the use twin screw extruders of granulation respectively such as resistance to tearing, barrier, heat sealability, consistency; temperature makes to intercept polymer at first by the stable near spherical many microfacies structure of dispersion formation under the interface stability effect of 160～200 shearing actions of spending and compatible polymer) or directly be mixed.Then under the orientation and stretching action of mouth mould and the pressure roller of extrusion calendaring machine, form many microbeddings sheet structure, and alternately stably be dispersed in layer by layer in the matrix of multiple material formation, having formed unique microcosmic layered composite structure, this class formation is " zigzag path " model.This microcosmic layered composite structure, the seepage that not only can prevent shoe polish, viscose glue and lipid, milk-food etc. significantly with separate out, show good barrier performance, and have reliable ultimate compression strength, resistance to tearing, heat sealability and surface printing performance etc., can satisfy the packing service requirements of general lipid and goods thereof.Secondly, this materials processing mode is selected single stage method for use, operates extremely simple possible, does not need special processing units.Once more, this material has not only been saved petroleum resources and bauxite resource owing to used polyolefine and an amount of inorganic powder, also is convenient to recycle because of not containing metals such as aluminium, and is also degradable.At last, this material has been owing to adopted design of unique material structure and unique processing process operational design, do not need multiple devices and recombining process repeatedly, and its cost is lower than traditional aluminium plastic composite material or multi-layer co-extruded material.
