Abstract
The invention discloses a plant fiber foaming packaging material. According to the packaging material, a density is 0.23-0.28g/cm<3> and a yield limit is within 850-1000N/cm<2>. The packaging material comprises the following components in parts by weight: 100 parts of plant fiber, 35-37 parts of corn starch, 2-4 parts of sodium carboxymethylcellulose, 1-2 parts of polyoxyethylene, 6-8 parts of wollastonite in powder, 12-14 parts of talcum powder, 6-8 parts of plant fiber modifier, 2-4 parts of organic silicon release agent and 1-2 parts of polyamide polyurea.
Description
Technical field
The present invention relates to field of packaging material, relate in particular to a kind of plant fiber foaming package material.
Background technology
Eps foam plastics are one of primary pollution source of contaminate environment, and according to " People's Republic of China's recycling economy promotion law " regulation, this product is on the verge of being replaced.But eps foam plastics light weight, flexible, as amortizing packaging material, there is no desirable substitute so far.
At present main substitute is pulp buffering wrapping material, and it, is dried and forms through slurrying, vacuum adsorption molding take paper pulp as raw material.Product application is in the industry such as small electronic apparatus, household electrical appliance.But goods are too fine and close, and impact resistance is poor, and resiliency is low compared with EPS expanded plastic.With a large amount of pulping woods.Pulping process polluted source.Production cost is higher than EPS expanded plastic cost.
Carry out in recent years the making of foamed plant fiber amortizing packaging material and the research of mechanism aspect both at home and abroad, obtained phasic results in various degree.
These goods add the material foaming such as starch and auxiliary agent and form take vegetable fibre as main raw material.Have free from environmental pollutionly, raw material sources are wide, and manufacture craft is simple, and cost is low, and shock-absorbing capacity is better than moulded paper pulp product.PSP company of Germany, blistering paper product process is first waste paper to be made after the mixing in 2: 1 of paper pulp and flour, injects and is squeezed into cylindrical particles, foams in extrusion process.Form blistering paper.Again blistering paper particle injection mould is produced to the goods of different geometries
Nantong Polytechnic College utilizes sponge to adopt inorganic foaming agent (CaHCO
3, NH
4be main) and organic binder bond and other additive, by integrated injection, one step foaming moulding, goods have certain resiliency.
Two whipping agent plant fiber foam materials of Wuhan green world development, under the effect of whipping agent, through low-temp foaming granulation, then through high temperature foaming.Goods have antidetonation, resistance to compression feature.
In sum, plant fiber foamed employing chemical foaming agent, foaming technique is simple, but production process has waste gas to produce, and corrosion mould, affects quality product.
Summary of the invention
The object of the invention is to propose a kind of plant fiber foaming package material, these wrapping material, take vegetable fibre and starch as major ingredient, coordinate appropriate additive, do not adopt whipping agent, to overcome the defect of bringing because of whipping agent of the prior art.
For reaching this object, the present invention by the following technical solutions:
A kind of plant fiber foaming package material, this wrapping material density is 0.23-0.28g/cm
3; Yield strength is at 850-1000N/cm
2between, these wrapping material are made up of following component in weight part: 100 parts, vegetable fibre, W-Gum 35-37 part, Xylo-Mucine 2-4 part, polyoxyethylene 1-2 part, wollastonite powder 6-8 part, talcum powder 12-14 part, vegetable fibre properties-correcting agent 6-8 part, silicone release 2-4 part, polymeric amide polyureas 1-2 part.
Preferably, these wrapping material are made up of following component in weight part: 100 parts, vegetable fibre, 36 parts of W-Gums, 3 parts of Xylo-Mucines, 1.5 parts of polyoxyethylenes, 7 parts of wollastonite powder, 13 parts of talcum powder, 7 parts of vegetable fibre properties-correcting agent, 3 parts of silicone releases, 1.5 parts of polymeric amide polyureas.
These wrapping material can be prepared as follows:
1) stalk is cut into long 8-12cm section, Yu Shuizhong soaks 8-10 hour, then defibrator process becomes fiber pulp, staple length is 1-5cm;
2) batching, respectively vegetable fibre, W-Gum, Xylo-Mucine, polyoxyethylene, wollastonite powder, talcum powder, vegetable fibre properties-correcting agent, polymeric amide polyureas and suitable quantity of water are added in mixing device according to the above ratio, mix, be prepared into pasty state;
3) smearing silicone release at die surface, then put into hot-press forming device, pasty state material is put into mould, is 0.85-0.95MPa at pressure, and die temperature is hot-pressing and foaming moulding at 145-155 ℃; Then cooling oven dry or dry.
Beneficial effect of the present invention is:
1) the present invention is take vegetable fibre and W-Gum as main raw material, and raw material sources are wide and renewable, meet recycling economy requirement.
2) with water vapour direct heat foam, inapplicable whipping agent, the environmental pollution in production and the use procedure of avoiding bringing because of the chemical property of whipping agent.
3) this foam package material quality is light, and outer wall is smooth, the inner closed bubble reticulated structure of hollow that forms, flexible, shock resistance, good heat preservation performance.Above-mentioned plant fiber foaming package material density is 0.23-0.28g/cm
3; Yield strength is at 850-1000N/cm
2between; Under naturally native underground layering part, the product 70-80% that degrades after 90 days.It is the ideal substitute of EPS expanded plastic and paper mould material.
