Abstract
The invention relates to biodegradable and photodegradable calcium plastic starch resin sheets, which are prepared by the following steps: (1) placing starch, glycerol and water into a high-speed mixer, stirring for 0.5 to 2 hours under a condition that the temperature is 140 to 160 DEG C, and obtaining plastic starch; and (2) placing the plastic starch, polyolefine resin and calcium carbonate, adding a proper amount of aid, uniformly mixing in the high-speed mixer, extruding in a double-screw extruder, and obtaining calcium plastic starch resin sheets with different thicknesses by rolling and cooling. The calcium plastic starch resin sheets prepared by the invention have high bursting strength, high tear strength and high pressure strength, can be subjected to chromaticity printing, have high naturally degradability, are biodegradable and photodegradable, can be recycled and are environment-friendly.
Description
Technical field
The present invention relates to a kind of biodegradable and photodegradative new calcium and mould the starch sheet material, belong to packing manufacturing field.
Background technology
At present both at home and abroad how papery corrugated cardboard tr does not possess moistureproof damp proof function, can only adopt waxing or composite plastic film is realized on the tr surface as having moistureproof damp proof function yet, or adopt the calcium of non-papery to mould corrugated packaging box.Common Corrugated Box loses intensity after making moist, receive to wet; And waxing or to mould carton technology again various, energy consumption is big, and influential to environment, is unfavorable for low-carbon environment-friendly.
The paper from calcium filled plastics case is claimed calc-plastic case again, is that to gather rare (HDPE) with high-density be main raw material(s), and lime carbonate is stopping composition, adds various auxiliary agents, and fluting line ball printing bookbinding becomes case after calendering heat glues into calcium to mould single corrugated panel.The great advantage of paper from calcium filled plastics case is that protection against the tide is not water funk, secondly is not frangible of good toughness, environment friendly and pollution-free recyclable utilization again.But the disadvantage of traditional paper from calcium filled plastics case is its plastic content up to more than 50%, in fact is difficult to degraded.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of moistureproof damp proof function that both had, and does not influence intensity again; But the calcium of surface chromaticity printing is simultaneously moulded the starch-resin sheet material.
Technical scheme of the present invention is: a kind of calcium is moulded the starch-resin sheet material, adopts the preparation of following step and gets:
(1) starch, glycerine and water are placed high-speed mixer by weight 1:0.8～1.2:0.8～5.0, under 140～160 ℃ of conditions of temperature, stirred 0.5～2 hour, make plasticized starch;
(2) plasticized starch, polyolefin resin, lime carbonate are mixed with weight ratio 1:0.8～1.2:1.5～2.5; After in high-speed mixer, mixing after the adding appropriate amount of addition agent; Under the polyolefin resin processing condition of correspondence, extrude with twin screw extruder, mould the shallow lake resin sheet through the calcium that rolls, different thickness is processed in cooling again.
Preferably, in the said preparation process,
(1) starch, glycerine and water are placed high-speed mixer by weight 1:1:1, under 140～160 ℃ of conditions of temperature, stirred 0.5～2 hour, make plasticized starch;
(2) plasticized starch, polyolefin resin, lime carbonate are mixed with weight ratio 1:1:2; After in high-speed mixer, mixing after the adding appropriate amount of addition agent; Under the polyolefin resin processing condition of correspondence, extrude with twin screw extruder, mould the shallow lake resin sheet through the calcium that rolls, different thickness is processed in cooling again.
Preferably, described auxiliary agent comprises oxidation inhibitor, coupling agent, stablizer, degradation of promoter and photosensitizers, is benchmark with total consumption of plasticized starch, polyolefin resin and lime carbonate, and the weight percentage of those auxiliary agents accounts for 0.5～1.5% respectively.
Preferably, be benchmark with total consumption of plasticized starch, polyolefin resin and lime carbonate, the weight percentage of oxidation inhibitor, coupling agent, stablizer, degradation of promoter and photosensitizers accounts for 1% respectively.
Preferably, described polyolefin resin is selected from Vilaterm or Vestolen PP 7052.
Preferably, described coupling agent adopts titanate coupling agent.
Oxidation inhibitor of the present invention recommends to use Hinered phenols antioxidant, as: 2, three grades of butyl of 6--4-methylphenol, two (3, three grades of butyl of 5--4-hydroxy phenyl) thioether, four (β-(3, three grades of butyl of 5--4-hydroxy phenyl) propionic acid) pentaerythritol ester etc.Preferably, described oxidation inhibitor model is 1010.
The present invention compares with background technology, has following beneficial effect:
1, calcium is moulded the thickness that the shallow lake resin sheet is pressed into common fluting board; Has water tolerance, non-hygroscopic, nonflammable; Has higher bursting strength, tearing toughness and ultimate compression strength; Can carry out chromaticity printing, can be used for being printed as wall calendar, the diploma etc., also can be used for making calcium and mould the shallow lake tr.
2, reduced the plastics usage quantity after the starch plasticizing, plastic content is merely about 20%, has good natural decomposition property, can biological degradation and photodegradation, also can recycling, and help environment protection;
3, can make certain thickness sheet material, can be used for substituting wooden building materials.
