Abstract
The invention discloses an easily decomposed corrugated container calcium-plastic material. The easily decomposed corrugated container calcium-plastic material is mainly prepared from following raw materilas by weight percentage: 18-23% of low-voltage polyethylene (HDPE), 30-42% of calcium carbonate, 7-13% of maize straw, 16-28% of calcium-plastic waste boxes, wherein the easily decomposed corrugated container calcium-plastic material comprises the following auxiliary materials by weight percentage: 3-5% of antioxidant, 0.3-0.7% of stearic acid, 2-3% of titanium dioxide and 2-3% of zinc stearate. The preparation method comprises the following steps: A, finishing materials: smashing the maize straw, sieving with a 50-80-mesh sieve, collecting the smashed maize straw powders for later use, smashing the calcium-plastic waste boxes, sieving with a 50-mesh sieve, and collecting the smashed calcium-plastic waste box powder for later use; B, mixing and stirring: uniformly mixing low-voltage polyethylene, calcium carbonate, the antioxidant, stearic acid, titanium dioxide, zinc stearate, the maize straw powder and the calcium-plastic waste box powder in a high-speed mixing machine, extruding in a double-screw extruder at the temperature of 140-160 DEG C, calendaring and cooling to obtain the calcium-plastic material with different thicknesses.
Description
Technical field
The present invention relates to and a kind of easily decompose corrugation case calcic-plastic composite material, particularly utilize calcic-plastic composite material to add maize straw in component, make its calcium-plastic corrugated board, tr, packing box etc. be easy to it at nature and degrade voluntarily, thus alleviate the pressure of environmental pollution.
Background technology
Calcic-plastic composite material is the wide a kind of wrapping material of current Application comparison, there is easy cleaning, corrosion-resistant, antifouling capacity is strong, and sound insulation, light weight, firm, moistureproof, seal the advantages such as better, gather rare (HDPE) for main raw material(s) with high-density, calcium carbonate is stopping composition, adding various auxiliary agent, moulding single corrugated panel, then through binding and molding through rolling hot sticky one-tenth calcium.But traditional calcic-plastic composite material shortcoming is that its plastic content is higher, plastics are degraded voluntarily at occurring in nature to be needed for a long time.In today of urbanization industrialization high speed development, the process of rubbish is the thing of the most headache of countries in the world government, in the middle of rubbish, plastics account for very large ratio, plastics are degraded also fast voluntarily by the effect of temperature difference wind and rain on earth's surface, buried plastics can reach even up to a hundredly to be stale-proof decades as concentrated, burning is the way of moulding that fast disappears, but burning can produce toxic gas, carcinogenic gas, its pollution level is higher than natural degradation.At proportions such as plastics discarded middle packing box, tr, art work, Plastic Bottles comparatively; Process approach for them has two aspects: 1 classification recycling, 2 add the material being easy to or urging its degraded in the component of plastics.Company of this group is through studying a kind of easily decomposition corrugation case calcic-plastic composite material for many years.
Summary of the invention
The object of the invention is the shortcoming for prior art existence and provide a kind of new calcium moulding material, it has the functions such as environmental protection, easily degraded.
For achieving the above object, the present invention adopts following technical scheme:
A kind of easily decomposition corrugation case calcic-plastic composite material, is characterized in that its major ingredient is made up of than raw material following weight: low pressure polyethylene (HDPE) 18%-23%, calcium carbonate 30%-42%, maize straw 7%-13%, calcium mould waste and old case 16%-28%;
Auxiliary material is made up of the raw material of following weight ratio: oxidation inhibitor 3%-5%, stearic acid 0.3%-0.7%, titanium dioxide 2%-3%, Zinic stearas 2%-3%.
Preferred plan of the present invention is realized: low pressure polyethylene (HDPE) 20%, calcium carbonate 37.5%, maize straw 11%, calcium mould waste and old case 22%, oxidation inhibitor 4%, stearic acid 0.5%, titanium dioxide 2.5%, Zinic stearas 2.5% by component weight part.
Preparation method of the present invention is: A material consolidation: corn straw smashing is crossed 50-80 mesh sieve, collects for subsequent use by the corn stalk powder through pulverizing, and calcium is moulded the fragmentation of waste and old case and crosses 50 mesh sieves, the calcium through pulverizing is moulded waste and old case powder and collects for subsequent use.
B mix and blend: low pressure polyethylene, calcium carbonate, oxidation inhibitor, stearic acid, titanium dioxide, Zinic stearas and corn stalk powder, calcium are moulded waste and old case powder and be placed in after high-speed mixer mixes, send into twin screw extruder at temperature 140-160 degree Celsius to extrude, then through rolling, cooling the calcium-plastic board material making different thickness.Calcium-plastic corrugated board, mould fluting board by the paper from calcium filled plastics on top layer, the calcium of sandwich layer, the paper from calcium filled plastics three layers of bottom forms laminate structure, the total thickness of plate is 3.6-4.2mm, corrugation muscle number is 18-20 bar/100mm, and each operation is followed successively by: prepare burden in proportion, mediate stirring, internal mixing and plasticizing, open refining plasticizing, four-roll calendaring, batch coil paper, three-ply paper is hot sticky, cooling forming.
Advantage of the present invention: environmental protection, light as wrapping material material, carry light, save transportation cost, save transport energy consumption, reduce the degree of environmental pollution.Turn waste into wealth, suitability for industrialized production can also make maize straw decrement discarded in agriculture production, reduces the possibility of crop straw burning.
Effect benefit fruit: the present invention is a kind of easily decomposes each material component in corrugation case calcic-plastic composite material and preparation method: low pressure polyethylene, calcium carbonate, corn stalk powder, calcium moulds waste and old case powder, oxidation inhibitor, stearic acid, titanium dioxide, Zinic stearas 8 kinds of materials are after mixing in abundant high-speed mixer, send into twin screw extruder at temperature 140-160 degree Celsius to extrude, again through calendering, the calcium-plastic board material of different thickness is made in cooling, because corn stalk powder is evenly mixed in wherein in calcium-plastic board material, compared with the calcium-plastic board material making calcium-plastic board material of the present invention and routine contain 45.5% calcium carbonate, its weight saving when same volume, calcium-plastic board material of the present invention at normal temperatures water soaks slowly and can not damage for 12 months, discardedly imbed underground after for wrapping material, corn stalk powder is less than wheat stalk density, easily expand after making moist warp, perishable numerous small holes hole of will rotting gradually after 2, numerous small holes hole is again water, the flowing of alkali provides favourable condition, the fragmentation that numerous small holes hole is monoblock calcic-plastic composite material provides just,
Advantage of the present invention: corn stalk powder rots to leave the degraded that alkaloid accelerates calcic-plastic composite material.Therefore the existing certain practical value of calcium-plastic board material of the present invention, has again minimizing environmental pollution.
