Abstract
Carbo lignius, graphite and active carbon other than carbon black used as far-infrared radiation raw materials are added to plastic material in the original plastic film preparation process, and polyethylene, polyvinyl chloride, polypropylene or nylon is used as film forming material.The far-infrared plastic film is used as mulching to cover crop so as to raise soil temperature, promote crop's growth and raise crop yield.
Description
The present invention relates to have the far plastics film of radiation, belong to field of plastics processing.
Before the present invention, the plastics film that people produce, in particular for the plastic film of agriculture aspect, its major function is to be used for soil moisture retention, also has certain insulation effect, but can not improve ground temperature, can not radiation infrared promotion plant-growth; The sooty far-infrared effect is better, therefore people are that raw material has been blown out black thin film with carbon black and new LDPE (film grade), the mulch film that is used for agricultural covering usefulness, even but carbon black add-on 1%, film has also become the lighttight film of black, this film can only be covered in and press down weeds between crop row, and can not be used for nurse crop, because the growth needs illumination of crop could be grown.
The objective of the invention is to be to overcome the deficiency of prior art, provide a kind of and can obviously improve ground temperature, and energy intense radiation far infrared rays is to promote the far infrared plastic film of plant growth.
The present invention realizes by following measures: a kind of have a radiation infrared plastics film, it is characterized in that making in the course of processing at plastic film, dose the far infrared filler, selected far infrared filler is a charcoal simple substance powder, its particle diameter is at the 1-100 micron, and filler accounts for plastic film gross weight 2-20%; Charcoal simple substance powder is meant carbo lignius, graphite, the gac except that carbon black; The filmogen of plastics is meant polyethylene, polyvinyl chloride, polypropylene, nylon.Find in the enforcement, charcoal simple substance is stratiform polycrystal structure, have good radiation infrared function, charcoal simple substance, graphite, gac also have good lubricity, so we select these charcoal simple substance powders as the radiation raw material of making the far infrared plastic film; Manufacture craft comprises operations such as the screening, oven dry, mixing granulation, blowing, reel, receipts film of filler; To the requirement of packing material size, mainly be in order to guarantee physical technique indexs such as goods stretch-proof, anti tear, to improve yield rate,, can carrying out the coupling agent surface now to filler for increasing amalgamation, conjugation and the dispersiveness of filler and plastics; To the requirement of filling adding amount, mainly be for the plastic film performance, add-on is low excessively, plastic film far-infrared radiation weak effect, add-on is too high, influences the transparency of plastic film, and the physical technique performance of plastic film, mechanical property reduce, as: plastic film is sent out plate, flexible reduction etc.Charcoal simple substance powder of the present invention can use separately, also can be several any compatibilities mix and use, as in order to increase other function, as: suppress weed growth, increase plastic film self photodegradation function etc., can a certain amount of weedicide of corresponding adding, photodissociation agent etc.; Identical during making with common plastic film manufacture craft, before the blown film, can mixing granulation, also filler and plastic powders etc. directly can be mixed blown film.
The present invention compares with the plastic film of prior art, has following advantage, far infrared plastic film of the present invention is easy to make, promptly under the constant situation of former plastic film manufacture craft, adding a certain amount of far-infrared radiation material makes, cover crop with far infrared plastic film of the present invention, comparable common film improves temperature 2-4 ℃ under equivalent environment, improves crop yield.
Embodiments of the invention: one, far infrared plastic film ratio of components: new LDPE (film grade): graphite microparticles=90: 10, graphite microparticles particle diameter≤5 μ m, blown film thickness: 8 μ m.
The said ratio material is through the mixing granulation blown film of routine, do the contrast experiment with this film and general thin, method is as follows: two kinds of film thicknesses are 8 μ m, choosing is with two mu on a slice ground, respectively cover 1 mu with two kinds of films respectively, cover the ground kind and be implanted with identical peanut, the peanut germination growth stage is adopted identical management process and measure, comprising: apply fertilizer, water; The result is as follows: cover two days later, its ground temperature of same timing, far infrared plastic film plot is 13 ℃, the general thin plot is 11 ℃, later two plot ground temperature differences are constant in always 2-3 ℃, and the germination of far infrared plastic film plot peanut early, and percentage of germination is high by 8% than normal film, far infrared plastic film plot peanut is than the harvest time of common plastic film 9 days in advance, and 72 kilograms of every mu of voluminous peanuts.Two, adopt low density linear polyethylene to make main filmogen, adopt active carbon powder as far-infrared material, its both proportionings are 95: 5; Gac powder particle diameter is 3 μ m, and it after 105 ℃ oven dry is dried down, is mediated granulation, blown film with polyethylene, and thickness is 4 μ m.
Select for use the common plastic film and the far infrared plastic film of present embodiment to oppose than test, method is as follows: two kinds of thickness are 4 μ m, choose with two mu of ground of a slice, respectively cover 1 mu with two kinds of films, all plant and be implanted with potato, planted in advance 6 days with the more common plastic film in far infrared plastic film plot, both bud ratios are identical, with 17 days in advance results in plot of common plastic film, the big quality height of the potato ball of being received, more common plastic film cover the plot and improve output 17% with far infrared plastic film plot.
Claims (3)
1, a kind of have a radiation infrared plastics film, it is characterized in that making in the course of processing at plastic film, doses the far infrared filler, and selected far infrared filler is a charcoal simple substance powder, and its particle diameter is at the 1-100 micron, and filler accounts for plastic film gross weight 2-20%.
2, far infrared plastic film according to claim 1 is characterized in that charcoal simple substance powder is meant carbo lignius, graphite, the gac except that carbon black.
