Description
Technical field
The present invention relates to a kind of plastics film, particularly a kind of plastics film of degradable anti-flaming.
Background technology
As everyone knows, the plastics bag made of plastics film is light, thin, waterproof, intensity is comparatively large, cost is low, a kind of well wrapping material, the use of plastics bag brings great convenience to the life of people, make the consumption of plastics bag increasing, not easily reclaim with waste plastic bag later, not easily degrade, a large amount of waste plastic bags has become the serious problem of of current contamination environment.In order to alleviate the pollution of plastics film to environment, people have developed some environment-friendly degradable plastic films, this kind of degradable plastic film, its moiety has film-grade plastics and can cause the component that plastics produce degraded, as starch, calcium carbonate etc., this degradable plastic film is addition type degradable plastic film, and addition type degradable plastic film is that environmental protect has played certain active effect.But the plastics film the physical property of product that the processing performance of this degradable plastic film processing is bad, make and outward appearance poor.
Biodegradable plastic is one of effective way of administering plastic refuse environmental pollution and buffering petroleum resources contradiction, from the packing bag of food to agricultural film, arrive the shell of electric equipment products again, from non-returnable container, edible products to product durable in use, biodegradable plastic just progressively replaces conventional plastic materials, and market outlook are very wide.It is reported, existing tens kinds of the biodegradable plastic kind of current global development,
In addition, the degraded of this degradable plastic film needs certain rigid condition, and plastics film discard after environment, done in the refuse disposal system closed, be exactly be exposed in the unfixed physical environment of condition, very difficult guarantor levies the rigid condition required for this degradation of plastic film, and no matter these degradative plasticss in most of the cases, are because can not degrade well by condition restriction in refuse disposal system or at physical environment.In prior art, do not have in the environment after discarded, the degradable plastic film of degraded to be ensured.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, proposing, in a kind of environment after discarding, to ensure the Degradable environment protection green plastic bag product of degraded.
Technical scheme of the present invention is:
A plastics film for degradable anti-flaming, its feed composition and parts by weight are respectively:
The preparation method of described nano flame retardant recombiner is:
(1) silicone hydroxyl phosphatic rock, red phosphorus, Attapulgite, hydrotalcite, polynite, titanium dioxide, calcite, kaolin are mixed according to the mass fraction proportioning of 25-35:15-20:10-15:10-15:8-10:8-10:7-8:5-7, join in the mixing solutions of 200 parts of methyl-sulphoxides (DMSO) and 50 parts of methyl alcohol, stir 60 hours in 65 DEG C, filter, and wash the excessive methyl-sulphoxide (DMSO) of 3 removings with the hot ethanol of 60 DEG C of temperature, put into vacuum drying oven, 60 DEG C of temperature dryings 24 hours, grinding is sieved, and obtains a modified flame-retardant mixture;
(2) by 1 part of modified flame-retardant mixture, 10 parts of Potassium ethanoates and 25 parts of distilled water mixing, more than 10 hours are stirred in temperature 50 C, in temperature 30 DEG C, first disperse 2.5 hours under ultrasonic electric power 350W condition, and then disperse 3 hours under ultrasonic electric power 250W condition.To filter, and with distilling washing 3 times, 80 DEG C of vacuum-drying 24 hours, grinding is sieved, and obtains twice-modified flame-retardant compounds;
(3) above-mentioned 1 part of twice-modified flame-retardant compounds is disperseed 40min at 600W power ultrasonic, be heated to 90 DEG C with constant temperature heating device, and stir (1200r/min) 60 minutes with mechanical stirrer; Obtain nano flame retardant mixture;
Described polyethylene is that Low Density Polyethylene, medium-density polyethylene, high density polyethylene(HDPE) are according to mass ratio 2:2:1 batch mixing.
PBM degradable material is the biodegradable material utilizing agricultural biomass resource to be main material production, be adopt starch, Vegetable oil lipoprotein etc. to synthesize for main raw material fully-degradable natural macromolecular material after special processing, form with water-soluble high-molecular material and a small amount of resin compounded, this PBM degradable material is commercial goods.
Described stopping composition is calcium carbonate.
Described oxidation inhibitor is antioxidant 1010 or irgasfos 168.
Advantage of the present invention and beneficial effect are:
Oxygen barrier provided by the invention and degradable plastic film select treated starch degradable plastics masterbatch PBM ripe in the market and Pullulan polysaccharide and film-grade LDPE blending extrusion blown film in preparation method, utilize the feature of LDPE, ensure the mechanical property that film is good; Utilize the degradability of PBM and Pullulan, realize the environment friendly of thin-film material; Utilize the height of Pullulan barrier, improve the barrier of thin-film material; Utilize starch and Pullulan as glucide similarity structurally, improve the consistency of plastic film material entirety; By the blended proportioning of control LDPE/PBM/Pullulan system, the regulation and control to barrier and degradability etc. can be realized.
Oxygen barrier provided by the invention and degradable plastic film can automatic classifyings under the effect of oxygen enrichment and microorganism, film after discarded can by the degradable digestion of occurring in nature microorganism, final generation carbonic acid gas and water, can improve 40% compared with the ldpe film oxygen barrier performance of same thickness.Preparation method's technique of the present invention is simple, production efficiency is high, industrializing implementation is easy, available common plastics inflation film manufacturing machine is produced.Fire retardant prepared by the present invention is not halogen-containing, organism, and asepsis environment-protecting, has a extensive future; The present invention carries out twice-modified, and such benefit is: increase reactive behavior point, improves modified effect; Can steam again except the moisture in system while modification, dry and modification is carried out simultaneously, improves working efficiency; There is a large amount of physics and chemistry planar water in self micropore such as nano silicone hydroxyapatite, Attapulgite, polynite, kaolin, at high temperature produce water vapor, block oxygen, absorb heat, reach multiple fire-retardant effect; Powerful absorption property effectively can improve the synergy of several fire retardant, stops and is raised by fire retardant matter temperature, improve flame retarding efficiency; The aboundresources such as silicone hydroxyl phosphatic rock, Attapulgite, polynite, kaolin, greatly reduces the industrial cost of fire retardant, also for the Application and Development of attapulgite provides a new way; The present invention adopt solution method ultrasonic wave disperse and mechanical high-speed agitator stir, make fire retardant separately component reach nano-scale dispersion in the solution, effectively prevent the natural oxidation to matrix material, thus make matrix material have better mechanical property.The oxygen index of matrix material is 41 tensile strength is 5MPa, and elongation at break is 120%, and degradation cycle is 120 days.
