Abstract
The utility model is related to flexible packing material technical fields, more particularly to the low-cost flame-retardant film of STP a kind of, the inflaming retarding membrane ecto-entad includes successively glass-fiber-fabric, pet film, aluminium foil film, pet film and linear low-density polyethylene film, and the glass-fiber-fabric, pet film, aluminium foil film, pet film and linear low-density polyethylene film are bonded by adhesive.A kind of low-cost flame-retardant film of the STP of the utility model, compared with inflaming retarding membrane in the prior art has the shortcomings that production difficulty is high, purchase cost is high and flatness is low due to comprising polyamide film, a kind of low-cost flame-retardant film of the STP of the utility model, polyamide film in the prior art is substituted using pet film, to have both the advantage that production difficulty is low, purchase cost is low and flatness is good.
Description
Technical field
The utility model is related to flexible packing material technical fields, and in particular to a kind of low-cost flame-retardant film of STP.
Background technology
STP(Super Thin Panel:Ultra-thin vacuum heat-insulating plate) be it is a kind of it is inorganic it is non-ignitable, with building with the service life
Novel building energy-saving material, can be with adhesive mortar, anticracking grout, finishing mucilage, fiberglass gridding cloth, finish coat, plasterboard
Equal materials collectively constitute green, environmental protection, low-carbon, energy-efficient heat-insulation system.
The inflaming retarding membrane that STP is used is to select aluminium foil and special type flame retardant proximate matter material as raw material and using unique advanced composite work
The dense film formed after skill is compound has high-gas resistance and anti-flammability.Multinomial experiment shows producing using the film
STP thermal insulation boards can ensure internal pressure≤10Pa within some time, and its thermal coefficient is not substantially within the scope of this
Become, it is ensured that the service life of STP planks；The film has very high flame retardant property, the heat preservation plate material produced simultaneously
National A grades of fire-protection standard can be reached, be gradually applied to architecture exterior wall insulating materials, largely filled up A grades domestic
The blank of fire-proof construction material.
The structure of the inflaming retarding membrane of existing STP is generally：Glass-fiber-fabric/pet film/aluminium foil film/
Polyamide film/linear low-density polyethylene film.
Although the inflaming retarding membrane of the STP of above structure, there is high-gas resistance and anti-flammability, but still scarce there are following three
Point：
First, the polyamide in the structure belongs to the material of the easy moisture absorption, thus brings difficulty, yield rate not high to production.
Second, the purchase cost of the polyamide in the structure is higher, and procurement cycle is longer.
The deflection of third, the polyamide in the structure is not high enough, causes the flatness of final products not good enough.
Based on the above issues, it is necessary to accordingly be improved for the structure of the inflaming retarding membrane of existing STP.
Utility model content
The purpose of this utility model is that being directed to deficiency in the prior art, and provide a kind of low-cost flame-retardant of STP
Film has both the advantage that production difficulty is low, purchase cost is low and flatness is good.
To achieve the above object, the technical solution that the utility model is taken is：A kind of low-cost flame-retardant film of STP, institute
It includes glass-fiber-fabric, pet film, aluminium foil film, poly terephthalic acid second to state inflaming retarding membrane ecto-entad successively
Terephthalate films and linear low-density polyethylene film, the glass-fiber-fabric, pet film, aluminium foil film,
Pet film and linear low-density polyethylene film are bonded by adhesive.
Wherein, the thickness of two layers of pet film is 10-14 μm.
Wherein, the thickness of the aluminium foil film is 5-9 μm.
Wherein, the thickness of the linear low-density polyethylene film is 75-85 μm.
Wherein, the adhesive is polyurethane.
The beneficial effects of the utility model：
The low-cost flame-retardant film of STP of the utility model a kind of, ecto-entad include glass-fiber-fabric, poly- terephthaldehyde successively
Sour glycol ester film, aluminium foil film, pet film and linear low-density polyethylene film, with existing skill
Inflaming retarding membrane has the shortcomings that production difficulty is high, purchase cost is high and flatness is low due to comprising polyamide film and compares in art,
The low-cost flame-retardant film of STP of the utility model a kind of substitutes the prior art using pet film
In polyamide film, to have both the advantage that production difficulty is low, purchase cost is low and flatness is good.
Description of the drawings
Fig. 1 is the structural schematic diagram of the low-cost flame-retardant film of the new STP of this reality.
Reference numeral：
1- glass-fiber-fabrics, 2- pet films, 3- aluminium foils film, 4- linear low-density polyethylene films.
Specific implementation mode
The utility model is further described with the following Examples.
It is the low-cost flame-retardant film of the new STP of this reality such as Fig. 1, ecto-entad includes glass-fiber-fabric 1, poly- terephthaldehyde successively
Sour glycol ester film 2, aluminium foil film 3, pet film 2 and linear low-density polyethylene film 4, it is described
Glass-fiber-fabric 1, pet film 2, aluminium foil film 3, the pet film 2 of ecto-entad
It is bonded by adhesive for polyurethane with linear low-density polyethylene film 4, the thickness of two layers of pet film 2
Degree is 12 μm, and the thickness of aluminium foil film 3 is 7 μm, and the thickness of linear low-density polyethylene film 4 is 80 μm.The ecto-entad
Glass-fiber-fabric 1, pet film 2, aluminium foil film 3, pet film 2 and linear low
Density polyethylene film 4 passes through dry type compoiste adhering successively.
Finally it should be noted that above example is only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, it will be understood by those of ordinary skill in the art that, it can be to the technical solution of the utility model
It is modified or replaced equivalently, without departing from the spirit and scope of technical solutions of the utility model.
