Abstract
A kind of heat-pesistant thin film, including the following raw material in percentage by weight：PERT 99% 100%, antioxidant 0% 1%.The film, it is not necessary to which specially doing modified technique can obtain heat-resist, can reach the other heat-pesistant thin film of aliment security level, nontoxic, environmentally friendly, health is mainly used in packaging for foodstuff and the high packaging material of other heat resistant requirements.
Description
Technical field：
The invention belongs to polymeric material field, and in particular to a kind of heat-pesistant thin film, be mainly used in packaging for foodstuff and other
The high packaging material of heat resistant requirements.
Background technology：
Heat-pesistant thin film material currently used for food-grade is all to be made using PE or PP by heat resistance modified, for requiring tight
Application in the packaging material for food of lattice can be very restricted.
PERT is heat-proof polythene, is a kind of noncrosslinking polyethylene that can be used for hot-water line, and also someone highlights it
Noncrosslinking characteristic, is named its " high temperature resistant non-cross-linked polyvinyl ".It is a kind of using special MOLECULE DESIGN and synthesis technique life
A kind of medium density polyethylene of production, it is obtained using the method for ethene and octene copolymer by the quantity and distribution that control side chain
Unique molecular structure, to improve PE heat resistance.Because the presence of octene short-chain branch makes PE macromolecular uncrystallizable one
In individual flat crystal, but it is applied in several crystal, forms the connection between crystal, it remains the good flexible of PE
Property, high thermal conductivity and inertia, while be allowed to resistance to pressure more preferably, this method of modifying is similar with common PPR in the market.
PE-RT pipes can be used for all use ranks of hot-water line specified in ISO10508, in building in cold and hot water system
Using for many years, with regard to reacting preferable from the point of view of the service condition of existing market, considerable hair has especially been obtained in terms of low-temperature ground heating
Exhibition.
Because PE-RT has excellent performance in terms of processing is extruded, crosslinking is not required to, speed of production is fast, and floor space is small,
Employment is few, therefore is mass produced manufacturer and is used.
The content of the invention：
Present invention mainly solves technical problem a kind of heat-pesistant thin film is provided.The film, it is not necessary to specially do modified technique
It can obtain heat-resist, the other heat-pesistant thin film of aliment security level, nontoxic, environmentally friendly, health can be reached.
In order to solve the above technical problems, the technical solution adopted by the present invention is as described below：
A kind of heat-pesistant thin film, including the following raw material in percentage by weight：PERT 99%-100%, antioxidant
0%-1%.
In a preferred embodiments of the invention, the PERT, its melt index is less than or equal to 2g/10min.
In a preferred embodiments of the invention, the antioxidant refers to primary antioxidant and auxiliary antioxidant compounding use, such as
Antioxidant 1010/168.
A kind of blown film preparation method of heat-pesistant thin film, specifically includes following steps：
Step 1: PERT, antioxidant are weighed according to being formulated into every trade；
Step 2: the material weighed up is put into mixer carries out mixing 3-6min, uniform rear taking-up to be mixed is standby；
Step 3: prepared by well mixed material feeding inflation film manufacturing machine or casting machine progress into film, specific processing temperature is：From
Feed end is to extruder terminal barrel temperature at 160 DEG C -200 DEG C, and head temperature is at 170 DEG C -200 DEG C.
Compared with prior art, its advantage is the present invention：(1), using PERT raw materials, the film prepared is resistance to
Hot height, reaches 120 DEG C；(2), with existing heat-pesistant thin film ratio, with cheap, nontoxic, environmentally friendly, health, available for food
Grade packaged material；(3), with existing heat-pesistant thin film ratio, with easy to process, it is easy to the advantages of being molded.
