Abstract
This invention publishes a kind of natural polysaccharide-based foaming materials, which by weight comprises 60~85% natural polysaccharides, 5~30% polyesters or other polymers, 2~5% plasticizers, 0.5~1.0% foamers and 4.0~10.0% water. This invention also publishes the preparation method for the natural polysaccharide-based foaming materials. This kind of materials performs good water resistant and humidity resistant activities and has the advantages of plenty of raw material sources and low cost.
Description
Technical field
The invention belongs to the wrapping material field, particularly be used for biodegradable filled-type shock-resistant packaging material of packings such as instrument, instrument and electrical equipment and preparation method thereof.
Background technology
Countries in the world are paid special attention to resource circulation utilization and recyclability, especially for non-returnable container material field, have used the material of recyclable utilization maybe can abandon the material that the back natural degradation becomes harmless micromolecular compound.The non-returnable container foam material that adopts the Biodegradable material preparation is the focus of studying at present, foreign patent US5,252,271 (Biodegradable packaging foam and method ofpreparation, 1993) employing starch is disclosed or treated starch is a raw material, be that whipping agent makes biodegradable packaging foam with the carbonic acid gas.Having had some producers that shock-resistant packaging material has been carried out research and Application and Development both at home and abroad, is the two-layer cardboard therebetween of the disclosed use of CN1083773A one deck starch based foam material as publication number; Publication number is that CN1292395A becomes particulate state with the disclosed starch foaming that makes of CN1127091A, is filled in the packaged instrument and equipment; Publication number is the disclosed corrugation folder one deck starch foaming material of using of CN2213131A, is bonded to sheet material then, is cut into difform packing articles again.The product of above several method development is in use all non-watertight, also will pass through other operations.
The foam material that is widely used in Shockproof packaging at present is polystyrene (being EPS), but the physical environment that has been difficult to " white pollution " serious harm that degradation property causes of polystyrene, so, people press for a kind of can the replace polystyrene wrapping material have good biodegradability properties can biodegradable material, and it is abundant that these wrapping material will possess raw material sources, the characteristics that cost is low.
Summary of the invention
One of purpose of the present invention provides biodegradable foam material, and discard after the goods of these wrapping material use and behind nature, be easy to be decomposed into carbonic acid gas and water, compliance with environmental protection requirements, in order to substitute the polystyrene foamed (being EPS) that is used for Shockproof packaging at present, thoroughly solve " white pollution " problem that degradation property causes that is difficult to because of polystyrene.
Another object of the present invention provides with the natural polysaccharide preparation method of the biodegradable foam package material that is base.
Of the present invention is the foam material of base with the natural polysaccharide, and by weight, its composition and content are:
Natural polysaccharide 60～85%
Polyester or other polymkeric substance 5～30%
Softening agent 2～5%
Whipping agent 0.5～1.0%
Water 4.0～10.0%
Described natural polysaccharide is ative starch, Mierocrystalline cellulose, hemicellulose, liquefying starch, open loop starch, treated starch, polyester graft starch or their any mixture etc.Described ative starch can be W-Gum, potato starch or tapioca (flour) etc.
Described polyester or other polymkeric substance are polycaprolactone, poly butylene succinate (PBS), poly--butyric ester (PHB), poly(lactic acid) (PLA), polyglycolic acid ester (PHAE), polyvinyl alcohol (PVA), polyvinyl vinyl alcohol (EVA) or their any mixture etc.
Described softening agent is water, glycerine, glyceryl monostearate or sorbyl alcohol etc.
Described whipping agent is Cellmic C 121, water or ethanol etc.
Of the present invention is the foam material of base with the natural polysaccharide, with natural polysaccharide, polyester or other polymkeric substance (biodegradable), softening agent, whipping agent, water, mix through high-speed stirring, reaction foaming granulation in screw extrusion press, obtain biodegradable foam material, as loose filling wrapper.Wherein, by weight, biodegradable foam material contains 60～85% natural polysaccharide, 5～30% polyester or other polymkeric substance, 2～5% composite elasticizer, 0.5～1.0% whipping agent, 4.0～10.0% water.
Natural polysaccharide and polyester or other polymkeric substance are after mixing in screw extrusion press, whipping agent discharges at extruder head, and the granulation of directly foaming changes the tap density of natural polysaccharide like this, alleviate the weight of unit volume, and improved the mechanical property and the processing characteristics of natural polysaccharide.The extrusion foaming prepared the good loose filled and process material of rebound resilience, apparent density is 0.03g.cm
-3～0.06g.cm
-3, rebound degree 60%～70%, moisture content 3%～5%, this material have waterproof, moisture-proof characteristic preferably.
Foam package material of the present invention is the biodegradable material with good biodegradability properties energy, and this material can be degraded to carbonic acid gas and water, and raw material sources are abundant, and cost is low.When utilizing shock-resistant packaging material of the present invention to prepare the Shockproof packaging goods, be to adopt extrusion foaming technology, be directly used in the Shockproof packaging of packed article.From preliminary Mechanics Performance Testing and cost keeping, and to the evaluation of its waterproof, anti humility performance, the natural polysaccharide based foam material of the present invention's preparation is used for the Shockproof packaging of small household appliances, communication product, has application promise in clinical practice.
