Abstract
The present invention aims at reducing environmental pollution. The mother material has calcium carbonate as main material, which accounts for 50-80%, and has also in its material polyolefine resin in 10-35%, photosensitizer 0.5-2%, photosensitive aid 1.5-3%, starch 0-30%, polyethylene/polyvinyl acetate copolymer 4-8% and aluminate as coupling agent 0.8-1.5%. The present invention also provides its production process. The degradable plastic is suitable for mulching, industrial and food packing bags, disposable tableware, etc.
Description
The present invention relates to a kind of photo-degradable and bio-degradable plastic matrix and production method technical field.
Plastics are used to prepare family expenses mulch film and packing film in a large number now, because in physical environment, plastics self are difficult to decompose, and remain in soil and the physical environment, the havoc Soil structure causes the pollution to soil and environment.Scientific and technical personnel research and develop the plastics of meeting self degradation for this reason, it as application number 95111274.0 Chinese patent " controllable light, biological double degradation plastic film and manufacture method ", it makes controllable light, bio-degradable master batch with new LDPE (film grade) and linear low density polyethylene, modified starch, photosensitizers, photosensitive accelerant, titante coupling agent, white oil through mixing, banburying, fragmentation, granulation, its shortcoming, must adopt treated starch, thereby the thing degraded takes place, and adopt the lime carbonate composition in the patent generally about 10～30%.As application number is that 95108845.9 Chinese patent " mother raw material degradable by light or organisms " also exists similar problem.
Therefore the object of the present invention is to provide a kind of optically and biologically degrading mother material, treated starch is optional in its formula constituent, and utilizes natural resources lime carbonate composition largely, thus can in and acid rain, stop in the rubbish and produce acid mist.
Another object of the present invention is to provide the production method of producing above-mentioned masterbatch.
Technical scheme of the present invention is to realize like this.This optically and biologically degrading mother material is characterized in that comprising following component (in mass percent)
Calcium carbonate particles 50～80%
Polyvinyl resin or acrylic resin or its mixture 10～35%
Photosensitizers 0.5～2%
Photosensitizer additive 1.5～3%
Starch 0～30%
Polyethylene/acetate ethylene copolymer 4～8%
Aluminate coupling agent 0.8～1.5% (is benchmark with lime carbonate)
Above-mentioned component also can contain thickened oil 1.5-3% (is benchmark with starch), glyceryl monostearate 1～4% (is benchmark with lime carbonate).
Above-mentioned photosensitizer additive can be calcium stearate or iron stearate or paraffin or its mixture, and above-mentioned photosensitizers can be aminoalkyl ferrocene derivative, and its order number of calcium carbonate particles is more than 800 orders, is preferably 1200 orders～1500 orders.
The production method of the above-mentioned optically and biologically degrading mother material of production provided by the invention is characterized in that steps in sequence is pre-treatment, with the surface treatment of dewatering of calcium carbonate particles, starch; The high speed heat seal is carried out heat seal with above-mentioned material under 200～900 rev/mins of 110～180 ℃ of temperature, rotating speed, add aluminate coupling agent and carry out surface treatment; Cold mix mixed polyvinyl resin or acrylic resin or its mixture and polyethylene/acetate ethylene copolymer, photosensitizers, photosensitizer additive with above-mentioned heat seal material; Granulation is at last with the extruding pelletization moulding on dual-screw pelletizer of cold mixed material.
Masterbatch of the present invention is mainly based on the selected lime carbonate that brightens of 1200 orders～1500 orders, its content surpasses 50%, it not only can reduce cost, but also good degradation effect is arranged, get nature, also nature determines it less to environmental hazard with the back, this composition does not contain heavy metal ion, its degraded product can not constitute underground water source and pollutes, simultaneously its spread in garbage bury factory, forest, the lake can in and acid rain, to keep ecological balance.High simultaneously lime carbonate of filling can have good photo damage in polyolefine, not having under the action of ultraviolet light, in air, carbonic acid gas and water erosion generate Calcium hydrogen carbonate down, promote the wetting ability of goods.And treated starch is not that biological degradation is essential, contains other inductor in the masterbatch, can promote biological degradation yet.
Below in conjunction with embodiment the present invention is further described.
