Abstract
The invention discloses a high-temperature-resistant food-grade preservative film which comprises the following components in parts by weight: 5-7 parts of A-MMA (acrylonitrile-methyl methacrylate copolymer), 8-13 parts of N-tert-butyl-ethyl-benzothiazole sulfenamide, 9-16 parts of acetone-diphenylamine pyrocondensate, 18-27 parts of diallyl isophthalate, 14-21 parts of initiator and 20-29 ethylene copolymer-asphalt blend. The preservative film has favorable high temperature resistance, can not easily release harmful substances at high temperature, and does not influence the health of the human body.
Description
Technical field
The present invention relates to preservative film field, particularly relate to a kind of high temperature resistant food grade preservative film.
Background technology
The food fresh keeping membrane brand that supermarket is sold is a lot, the Function Identification that large multi-brand introduces preservative film mostly is " thickening " " fresh-keeping " etc., what substantially mark is " PE material " and nontoxic mark, major part has all marked the essential informations such as producer, date manufactured, dimensions, material, only had the preservative film of individual brand to indicate " food packaging " or " refrigerator and microwave oven be suitable for ", some even what mark do not have yet.Some can not be placed on the preservative film heated in microwave oven, also do not have caveat such as " must not applied at elevated temperature ", and just designate " normal temperature, refrigerator use ".Although the preservative film of some brand " PVC " printed words at full position mark, not warning " can not contact zones fatty foods " etc.Many human consumers buy preservative film and generally just see price and specification, understand very few to the kind of preservative film, general knowledge.
But the resistance to elevated temperatures of the preservative film used at present is poor, at high temperature easily discharges objectionable impurities, brings harm to the health of human body.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of high temperature resistant food grade preservative film, and resistance to elevated temperatures is good, at high temperature not easily discharges objectionable impurities, does not impact the health of human body.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of high temperature resistant food grade preservative film, this preservative film comprises A/MMA vinyl cyanide/methylmethacrylate copolymer, the N-tertiary butyl-ethyl-benzothiazole sulphenamide, BLE, diallyl isophthalate, the blend of dimethyl terephthalate (DMT) and ethylene copolymer-pitch, the weight content of its each component is: A/MMA vinyl cyanide/methylmethacrylate copolymer 5 ~ 7 parts, the N-tertiary butyl-ethyl-benzothiazole sulphenamide 8 ~ 13 parts, BLE 9 ~ 16 parts, diallyl isophthalate 18 ~ 27 parts, the blend 20 ~ 29 parts of initiator 14 ~ 21 parts and ethylene copolymer-pitch.
In a preferred embodiment of the present invention, described initiator is dimethyl terephthalate (DMT).
In a preferred embodiment of the present invention, the weight content of the blend of described ethylene copolymer-pitch is 25 parts.
In a preferred embodiment of the present invention, the weight content of the described N-tertiary butyl-ethyl-benzothiazole sulphenamide is 11 parts.
The invention has the beneficial effects as follows: resistance to elevated temperatures of the present invention is good, at high temperature not easily discharges objectionable impurities, the health of human body is not impacted.
