Abstract
The invention provides a photodegradable high-temperature-resistant plastic preservative film, belonging to the technical field of household plastic materials. The preservative film is composed of plastic base materials, a plasticizer, an anti-oxidant, a flexibilizer, a dispersant and a photosensitizer, wherein ratio of each component is 100-130 parts of the plastic base materials, 1-2 parts of the anti-oxidant, 1-2 parts of the flexibilizer, 0.5-1 part of the dispersant, 3-7 parts of the photosensitizer and 0.5-1 part of other additives. According to the invention, the raw materials are easily available and cheap. The plastic is degraded by utilizing light sensitivity of nano-titanium dioxide, and residues after the photodegradation do not influence the environment. The preservative film provided by the invention can be heated to 260 DEG C, does not generate harmful substances to bodies whether in everyday preservation of food, fruits and vegetables, or during heating, and is a degradable environmental-protective product.
Description
Technical field
The present invention relates to photodegradation high-temperature resistance plastice preservative film, belong to Domestic plastic material technology field.
Background technology
Along with the quickening of people's rhythm of life, preservative film has entered into increasing family, prevents the food taint of odour in refrigerator, prevents the moisture excessive evaporation during microwave-oven-heating and makes food exsiccation hardening etc.the preservative film that uses at present generally is divided three classes: polyethylene, polyvinyl chloride and polyvinylidene dichloride, and especially with polyethylene use many, but common polyethylene preservative film can not heat, heating can make the additives for plastics in preservative film decompose out, health is damaged, and the increase along with the plastics usage quantity, environmental problem is also day by day serious, because plastics are hard degradation under field conditions (factors), even be embedded in the underground, also be difficult in a century and can degrade, therefore, can only burn or recycle, but can send pungent niff when burning, and can not burn thoroughly, have the residue of black and can not reuse, therefore burn method inadvisable, recycled plastic needs certain cost, and if plastics itself adhere to material messy and that be not easy to remove after using, need to clean when reclaiming, this just needs a large amount of clean-out systems, cost is high, do not calculate.Therefore a lot of degradative plasticss have appearred in recent years, the degradative plastics that occurs at present is divided into photodegradable plastics, biodegradable plastic, Photo biodegradable plastics and water degradative plastics, wherein again with the low cost of photodegradable plastics, palliating degradation degree fully, characteristics such as environmental protection and enjoy attention.The preservative film that uses in the market is still waiting development at aspects such as high temperature resistant, degradeds.
Summary of the invention
In view of the defective that prior art exists, the purpose of this invention is to provide a kind of photodegradable, not only to be used for common vegetables and fruits fresh-keeping but also can be used for the photodegradation high-temperature resistance plastice preservative film of microwave oven heat.
For achieving the above object, the technology used in the present invention solution is: photodegradation high-temperature resistance plastice preservative film, be comprised of plastic matrix, softening agent, oxidation inhibitor, toughner, dispersion agent, photosensitizers, wherein each component proportion is: 100 ~ 130 parts of plastic matrixs, 1 ~ 2 part, oxidation inhibitor, 1 ~ 2 part of toughner, 0.5 ~ 1 part of dispersion agent, 3 ~ 7 parts of photosensitizerss, 0.5 ~ 1 part of other auxiliary agent.
Described plastic matrix is the mixture of polyethylene and polyvinylidene dichloride, and wherein the proportioning of polyethylene and polyvinyl chloride is 5:1 ~ 3.
Described oxidation inhibitor is 2,6-tributyl-4-methylphenol.
Described toughner is a kind of in polyvinyl alcohol, Vinyl Acetate Copolymer.
Described dispersion agent is a kind of in derivatived cellulose, polyacrylamide.
Described photosensitizers is nano titanium oxide, and particle diameter is 5 ~ 15nm.
Described other auxiliary agents are nano-tourmaline crystal grain, and particle diameter is 20 ~ 50nm.
In the present invention, the raw material of each component is easy to get, and low price, utilizes nano titanium oxide to the responsive of light and then makes plastic degradation, and the later residue of photodegradation can not impact environment.Heating temperature of the present invention can not produce insalubrious material during at daily vegetables and fruits food fresh-keeping, still in heating up to 260 ℃, belongs to the Degradable environment protection product.
