Abstract
The present invention relates to a double foamed plant fiber packing material which is prepared form the components by dry basis weight ratio: 30 to 70 of plant fiber, 10 to 40 of plant starch, 5 to 30 of filling material, and auxiliary materials, namely 0.5 to 4 of starch modifying agent, 0.1 to 1 of softening agent, 0 to 1 of anti-mildew agent, 0.5 to 6 of foaming agent and 1 to 6 of water proof agent. The present invention has the advantages of rich raw material resource for production, low price, no three wastes in production processes, no environmental pollution, light weight, high shock and compression resistance, moisture protection and mildew protection. Moreover, the present invention is easily degraded into organic fertilizer for recycling, and the present invention is suitable for the industrialized production.
Description
Technical field
The present invention relates to a kind of industrial products and mainly be the packing, particularly double-foamed plant fiber packing material of various electrical equipment and instrument, meters product.
Background technology
Popularizing of development of making rapid progress along with industry and household appliances, the product packaging material demand is increasing, extensive market; At present, widely used industrial product is a foam plastic product on the market; Secondly, be substitute products---paper pulp moulding product; Although the foamed plastic packaging product of industrial products employing now is in light weight, the resistance to compression shock strength is better, easy to use; But due to the characteristic of (be difficult for degraded, contaminated environment) of foam plastic product self, the result of long-term use will bring huge harm to ecology environment, thereby threatens mankind itself's living environment; Now, plastic product has caused the great attention of various countries to the influence of ecology environment; For addressing this problem, the paper pulp moulding product that be easy to natural degradation, is easy to reclaim arises at the historic moment, but its productive costs is accompanied by a large amount of waste water and discharges apparently higher than foaming foam plastic product in the production process, environment is had to a certain degree influence, and its antidetonation cushion characteristic is relatively poor.
Summary of the invention
The objective of the invention is,, improve, propose and the research double-foamed plant fiber packing material at the deficiencies in the prior art; Its basic conception is, the new package material that uses easily degraded vegetable fibre free from environmental pollution again and plant amylum to make as raw material is got for foam plastic product, vegetable fibre and the plant amylum raw material sources are extensive, cheap, productive costs is low, do not have " three wastes " in the production process, free from environmental pollution, product weight light, mildew-resistant, protection against the tide, resistance to compression shock strength are good; Product uses back waste meeting natural degradation, can become organic fertilizer after the degraded.
Technical solution of the present invention is that to have adopted vegetable fibre, plant amylum, filler, auxiliary material be raw material;
It is characterized in that auxiliary material includes starch modifying agent, hand modifier, anti fouling composition, foaming agent and water repellant;
It is characterized in that the butt weight ratio of vegetable fibre, plant amylum, filler, starch modifying agent, hand modifier, anti fouling composition, foaming agent and water repellant is:
Vegetable fibre 30-70
Plant amylum 10-40
Filler 5-30
Starch modifying agent 0.5-4
Hand modifier 0.1-1
Mildew inhibitor 0-1
Foaming agent 0.5-6
Water repellant 1-6
It is characterized in that vegetable fibre is the composite of a kind of in agricultural waste material straw, rice wheat straw, cotton linter, bagasse, waste paper, the Chinese alpine rush or two or more material;
It is characterized in that plant amylum is the composite of a kind of in starch from sweet potato, sweet potato powder, cornstarch, corn flour, potato starch, tapioca starch, the ground rice or two or more material;
It is characterized in that hand modifier is a kind of of glycerine, calcium stearate, zinc stearate, starch modifying agent be zinc acetate, glyoxal, the composite of a kind of in the phosphoryl chloride phosphorus oxychloride, chloropropylene oxide or two or more material; Mildew inhibitor is a kind of of Sodium Benzoate, calcium propionate, sodium salicylate; Foaming agent is unifor, Celogen Az, 4, the composite of 4-OBSH, sodium bicarbonate, urea a kind of or two or more material;
It is characterized in that filler is inorganic filler, as the composite of a kind of or two or more material in calcium carbonate, french talc, china clay, amargosite, the titanium dioxide;
It is characterized in that water repellant is the composite a kind of or material more than two kinds in rosin breast night, wax emulsion, the polyacrylic acid emulsion;
Advantage of the present invention is, rich raw material sources, and cheap, production process does not have " three wastes ", free from environmental pollution, product weight is light, the resistance to compression shock strength is good, moistureproof, mildew-resistant, and be easy to degraded, and can be used as organic fertilizer after the degraded, the present invention is suitable for suitability for industrialized production.
The specific embodiment
Below, describe embodiments of the invention in detail.
At first, according to the synthetic requirement of technology, carry out degenerative treatments to producing base stock plant amylum of the present invention.By weight, water intaking 79.5%, plant amylum (starch from sweet potato, cornstarch, potato starch, corn flour, sweet potato powder, mandioca meal, the composite of a kind of in the ground rice or two or more material) 15%, hand modifier (glycerine, calcium stearate, the composite of a kind of in the zinc stearate or two or more material) 1.0%, water repellant (rosin breast night, the wax emulsion, the composite of a kind of in the polyacrylic acid emulsion or two or more material) 3%, above-mentioned material is put into retort in order, warm-up control heats up 20 ℃-90 ℃ while stirring, add starch modifying agent (zinc acetate, glyoxal, phosphoryl chloride phosphorus oxychloride, the composite of a kind of in the chloropropylene oxide or two or more material) 1.5%, reaction is filtered after finishing, washing and dry, reclaim starch; Next, get fiber (agricultural waste material straw, the rice wheat straw, cotton linter, bagasse, the composite of a kind of in the Chinese alpine rush or two or more material) 70%, modified starch 20%, foaming agent (unifor, Celogen Az, 4, the 4-OBSH, sodium bicarbonate, the composite of urea a kind of or two or more material) 4%, mildew inhibitor (Sodium Benzoate, calcium propionate, the composite of a kind of in the sodium salicylate or two or more material) 0.5%, filler (calcium carbonate, french talc, china clay, amargosite, the composite of a kind of in the titanium dioxide or two or more material) 10%, add two Luo bars and extrude bulking equipment; Under 40 ℃-90 ℃, extrude the swelling granular of diameter 0.5-3 millimeter, swelling granular is blown in certain die cavity again, under 100 ℃-150 ℃ and pressure effect, become fine and close packing after making swelling granular through the secondary frothing forming operation, the shape of these packing is different and different according to the shape of the particular manufacturing craft of selecting for use.
