Abstract
The present invention provides a kind of fire-retardant heat shrink films, including following parts by weight material：PET resin 55 65%, plasticizer 4 7%, light stabilizer 1 5%, antioxidant 1 2%, lubricant 5 6%, bromide fire retardant 5 10%, fire retarding epoxide resin 5 10%, antistatic agent 1 3%.A kind of fire-retardant heat shrink films provided by the invention are bromide fire retardant and fire retarding epoxide resin respectively, since its excellent performance makes the heat shrink films good flame retardation effect being prepared using two kinds of fire retardants as raw material.
Description
Technical field
The present invention relates to a kind of fire proofings, and in particular to a kind of fire-retardant heat shrink films and manufacturing method.
Background technology
Demand of the current packaging industry to heat shrink films is increasing, application range also not short expansion, but existing
Technology in heat shrink films performance it is single, intensity is low, cannot be effectively effectively fire-retardant when fire occurs, so need one
The good heat shrink films of kind flame retardant property..
Invention content
One of the technical problem to be solved of the present invention is the anti-flammability of promotion heat shrink films, and the two of problem is to carry
For the manufacturing method of this fire-retardant heat shrink films.
The present invention solves above-mentioned technical problem using following technical scheme：
A kind of fire-retardant heat shrink films, including following parts by weight material：
PET resin 55-65%
Plasticizer 4-7%
Light stabilizer 1-5%
Antioxidant 1-2%
Lubricant 5-6%
Bromide fire retardant 5-10%
Fire retarding epoxide resin 5-10%
Antistatic agent 1-3%.
Further, the plasticizer is phthalic ester plasticizer or phosphate.
Further, the light stabilizer is hindered amine light stabilizer.
Further, the antioxidant is phosphite antioxidant.
Further, the bromide fire retardant be brominated Polystyrene, deca-BDE or tetrabromobisphenol A in one kind or
Two kinds.
Further, the fire retarding epoxide resin is nitrogenous fire retarding epoxide resin or siliceous fire retarding epoxide resin.
Further, the antistatic agent is fatty alcohol polyoxyethylene ether.
The manufacturing method of this fire-retardant heat shrink films, includes the following steps：
1) above-mentioned raw materials are weighed；It is added in reaction kettle, 6h is stirred to react at 250-260 DEG C and obtains polymer melt, stir
Speed is 180-200rpm, then by polymer melt extruding pelletization, is dried to obtain PET slices；
2) PET obtained in step 1) is sliced melting extrusion, slab stretches, cooling and shaping obtains the fire-retardant thermal contractions of PET
Film.
Further, the draft temperature is 130-140 DEG C.
The advantage of the invention is that：
Fire-retardant heat shrink films provided by the invention use two kinds of fire retardants as raw material, are bromide fire retardant respectively and fire-retardant
Epoxy resin so that the heat shrink films good flame retardation effect being prepared.Contain vivaciously wherein in fire retarding epoxide resin strand
Epoxy group, epoxy group can be located at the end of strand, centre or circlewise structure.It is active due to containing in molecular structure
Epoxy group, make them that can be crosslinked with curing agent such as amine, phenols, anhydrides and react and form insoluble, insoluble tool
There is the high polymer of tridimensional network.Epoxy resin after solidification has good physics, chemical property, it is to metal and Fei Jin
The surface for belonging to material has excellent adhesive strength, and dielectric properties are good, and set shrinking percentage is small, and product size stability is good, firmly
Degree is high, and flexibility is preferable.
Specific implementation mode
It is described in detail below in conjunction with to the present invention.
