Abstract
The present invention relates to one kind of composite for producing foamed plant starch packing material capable of being degraded completely and its use. The composite consists up to 90% of plant starch as main material and small amount of plant fiber, foaming agent and machining assistant and is produced into foamed packing material in certain shape through extrusion in a single screw extruder or molding. The composite material is light, with density of 0.05-0.1 g/cu cm, shockproof, heat insualting, sound isolating and degradable completely. The used material may be recovered and reused as feed or fermentation material for producing industrial alcohol and glucose. The composite material may be used to replace polyethylene, polystyrene and other foamed material for packing, heat insulation, etc.
Description
Invention field
The present invention relates to a kind of composition, the purposes of said composition, the purposes in the foam package material that can degrade fully of preparation especially, and by the foam package material of said composition preparation.
Technical field
Because the widespread use of Plastic Packaging Materials, abandonment just seriously threatens human existence at the waste or used plastics of occurring in nature to " white pollution " that environment causes, prevent, administer " white pollution " and caused the concern of countries in the world, research and development degradable package material is the important channel that solves " white pollution ".
Plastics are raw materials used to be from non-renewable petroleum resources, tellurian petroleum resources are limited, and are mainly used in the energy, so, the present invention utilizes renewable plant amylum to be main raw material, substitutes petroleum resources production degradation material and has prior meaning.
Ordinary resin such as PE, PP, PS etc. produce the early existing issue of patent of bio-degradable plastics with the plant amylum blend, and also have many products to appear on the market under the effect of expanding material.But because starch and resin polarity difference are too big, the loading level of starch generally is no more than 30%, so-called starch is dosed the type bio-degradable plastics, in fact can only be that wherein starch under certain condition can be by microbiological degradation, and 70% remaining above resin partly is difficult to decomposition.
Summary of the invention
The purpose of this invention is to provide a kind of composition of degrading plant starch foaming wrapping material fully that is used to produce.Composition of the present invention comprises:
(A) plant amylum of 70-90% and/or plant powder;
(B) 5-15% vegetable fibre;
(C) 0.5-1% whipping agent;
(D) auxiliary agent of 4.5-15%.
Described % all is base with the composition total weight.
Described starch is selected from general industry starch, as W-Gum, yam starch, sweet potato starch, tapioca (flour) etc. and their modifier, and as Sumstar 190, cationic starch, cross-linking starch, starch ester etc., and these two or more binding substances.Described plant powder is that plant seed, stem tuber, root or leaf are directly pulverized the powder that forms, as wheat-flour, Semen Maydis powder, rice meal, sticky rice flour, potato powder, sweet potato flour, Tapioca Starch etc., the perhaps binding substances of these two or more.
Described vegetable fibre is selected from xylon, cotton fibre, straw fiber, reed fiber, crop branch fiber, waste paper pulp and their modifier, as carboxymethyl cellulose, carboxyethyl cellulose, cellulose ester or ether of cellulose etc., and two or more binding substances in them.
Described whipping agent can be a pneumatogen, as lower boiling aliphatic hydrocarbon, alcohol, ether, halohydrocarbon or water etc.Also can be chemical foaming agent, as Cellmic C 121, azo two carbonic acid diisopropyl esters, sodium bicarbonate, volatile salt etc., perhaps these binding substances.
Described auxiliary agent comprises: strengthening agent, as glass fibre, asbestos powder, Paris white, wollastonite powder etc.; Tackifier are as polyvinyl formal, gelatin, polyacrylic acid emulsion, Sorbic Acid, glycerine, polyvinyl alcohol etc.; Releasing agent is as silicone oil, solid paraffin, polyethylene wax, stearic acid, whiteruss etc.; Also can be according to the optional a spot of insect-proof agent that adds of different application needs, sanitas, non-blushing thinner etc.Various auxiliary agents use with the conventional amount used in this area, and this is to determine easily to one skilled in the art.
Foam package material involved in the present invention does not conform to any resin, wherein all natural polymer starch and Mierocrystalline cellulose renewable and that can be decomposed by Institute of Micro-biology more than the 90-95%, the remaining various auxiliary agents of 5-10% also all belong to degradable components, so the prepared foam package material of this invention is the Wholly-degradable material.
Treated starch or modified-cellulose are compared with common starch or Mierocrystalline cellulose, and its chemistry is significantly improved with physicals, can increase the strength of materials, improves the material frothing percentage, but does not influence biological degradability, so treated starch and modified-cellulose are preferred.
Starch or plant powder itself is as foam material body material of the present invention, and its mechanical property does not reach application requiring far away, except that improving the intensity by its modification, adds various auxiliary agents and is absolutely necessary.The selection of various auxiliary agents also must have consistency preferably with body material except that consideration self degradation property.In order to improve consistency, also should contain the compatibilization component in the auxiliary agent.
The processing units that the present invention prepares the foam package material employing of can degrading fully is common mixing equipment, single screw extrusion machine and heating and mould pressing molding device.Facility investment is few, and technology is simple, non-environmental-pollution.
The method for preparing foam package material of the present invention comprises with water being medium, after the auxiliary agent of the plant amylum of 70-90% or plant powder, 5-15% vegetable fibre, 0.5-1% whipping agent and 5-15% mixed, use various forming methods, for example single screw extrusion machine or hot compression molding machine moulding process are prepared from.This material is white in color or oyster white, and density is 0.1-0.05g/cm
3, can satisfy the requirement of packing use properties.
For example processing and forming technology can carry out like this, by a certain percentage all raw materials are mixed with water, thorough mixing is even in homogenizer, make the big material of dough shape, then big material is transported in the single screw extrusion machine, extrusion temperature is 180-190 ℃, extrusion moulding or join in the heat pressing forming machines according to the certain big material of the big young pathbreaker of mould, temperature is 180-200 ℃, and pressure is 0.1-0.5Mpa, clamp time 50-60S compression moulding.
The present invention's foam package material of can degrading fully, mainly as Shockproof packaging, sound insulation, lagging material, reclaim and also can be used as animal-feed or fermentative production industrial spirit, hydrolysis production glucose except that can degrading fully with the back.
