Abstract
The present invention relates to a nano polypropylene multilayer packaging material and preparation method of its product. It is technically characterized by that it utilizes polypropylene powder material and nano-grade silicone dioxide to form its internal layer and external layer, and utilzies nano-grade silicone dioxide, titanium dioxide and zinc oxide as raw material and polypropylene and polyethylene synthetic resin to form core layer, and places said core layer between the internal layer and external layer so as to make nano-grade raw material insert into gap between molecular chains of polypropylene resin to form new packaging material. it can be extensively used as package of food and beverage.
Description
Technical field: the present invention relates to the preparation technology of a kind of packaging material and goods thereof, the preparation method of particularly a kind of multilayered nano poly propylene packaging material material and goods thereof.
Background technology: at present, be used for the packaging material of food, beverage, medicine and cosmetics etc., be essentially materials such as glass, metal or paper be compound.The goods of glass material as: bottle, cup etc. are not only easily broken, and own wt is big, and transportation, storage were both dangerous, convenient, and cost is high again, and its complex manufacturing, labour intensity are big, big energy-consuming, environmental pollution are serious.The goods of metal material are as jar, box etc., cost price height not only, and it makes comparatively complicated, the equipment investment amount is big, the goods of paper, plastic composite materials as: though cost prices such as cup, box, jar are cheap, own wt is light, but mostly be disposable use, be difficult to handle after it is discarded, cause environmental pollution easily.
Summary of the invention: technical problem to be solved by this invention is: a kind of of many uses, economic security, environmentally safe are provided, and make the multilayered nano poly propylene packaging material simple, that equipment investment is less and the preparation method of goods thereof.
Its technical scheme is:
A kind of multilayered nano poly propylene packaging material are made up of internal layer, skin and sandwich layer, it is characterized in that:

C) raw material components of sandwich layer and percentage by weight are:
Isotactic polypropylene: 20-30 random polypropylene: 10-20
Low molecular polyethylene: 10-20 ethylene-vinyl alcohol copolymer: 45-55
Nanometer grade silica: 0.1-2 Nano titanium dioxide: 0.1-5
Nano-class zinc oxide/or the nanoscale carbon granules: 0.1-1.5 silane: 0.01-0.1
Sorbierite: the 0.001-0.01 class is covered holder soil: 0.1-4
A kind of preparation method of multilayered nano poly propylene packaging material goods is characterized in that:
(1) material is made
With nano level silica and silane, sorbierite mixed grinding mix with the copolymerization polypropylene powder stir the internal layer material;
With nano level silica and silane, sorbierite mixed grinding mix with the isotactic polypropylene powder stir outer material;
With nano level silica, titanium dioxide, carbon granules/or zinc oxide and silane, sorbierite, class get the sandwich layer material with ethylene-vinyl alcohol copolymer, isotactic polypropylene, random polypropylene, low molecular polyethylene material blending and stirring again after covering the native mixed grinding of holder.
(2) pipe is made:
Internal layer material, outer material and sandwich layer material are dropped into three extruders respectively, and the material of extruding through extruder is the multilayer pipe;
(3) pipe is sent into mould after blow packaging product.
Multi-layer packaging material of the present invention, because it is nucleator that its inside and outside layer all adopts acrylic resin to add nano level silica, thereby can make acrylic resin degree of crystallinity improve its surface-brightening, transparent, have higher toughness, definition and intensity, safe in utilization; Its sandwich layer since adopt nano level silica, titanium dioxide, zinc oxide/or raw material such as carbon granules constitute the sandwich layer that places between inside and outside layer with the blend of synthetic resin raw material, thereby has a function of gases such as blocking oxygen and carbon dioxide, can be widely used in anticorrosion, fresh-keeping, the packing of protecting requirement such as fragrant, antirust to food, beverage, medicine and cosmetics, and because packaging material of the present invention are mainly the lower acrylic resin raw material of the market price, therefore, its cost price is low, has the stronger market competitiveness.Adopt packaging material of the present invention to make relevant packaging product, its technology is simple, makes easily, and equipment investment is also little.Its goods can also reclaim after discarded through using; be processed into polyacrylic fibres or fiber after treatment; can be made into the reconstituted product of classes such as work clothes, sleeping bag, carpet, rope, sandwich layer, skin, the internal layer of the opaque packaging product of also reusable making material is of value to environmental protection.
