Abstract

The utility model discloses a multilayer air-sealed heat insulation film which comprises a plurality of layers of flame-retardant films and a plurality of layers of square and reticular flame-retardant framework films, wherein the flame-retardant framework films are clamped between each layer of flame-retardant films and are fixed with the flame-retardant films together so as to form at least two film layers on which a plurality of sealed air bubbles are continuously distributed; fireproof fabric layers are fixed on the outer sides of the flame-retardant films. According to the multilayer air-sealed heat insulation film, the problems in the prior art that the heat insulation quilt is high in self-weight and difficult to operate and can perform certain harm to the health are solved.

Description

Multilayer occluded air heat-insulating film

Technical field

The utility model belongs to heat preserving and insulating material technical field, is specifically related to a kind of multilayer occluded air heat-insulating film.

Background technology

The northern area of China entered after winter, generally adopted spun-glass insulation cotton-wadded quilt to be incubated covering measure in building engineering construction field.The shortcoming of this heat-preservation cotton quilt be unit are from great, construction labour intensity is high, can only cover the region that will be incubated with whole Zhang Yici, can not carry out cutting splicing according to design feature, for the winter construction insulation of vertical structure due to can not be effectively fixing, make the situation of enduring cold in part become normality, construction quality is brought to negative effect.And once spun-glass insulation cotton-wadded quilt is in use damaged, the glass fiber flying is very easily infected with operating personnel's skin and clothing, cause pruitus and be difficult to cleaning, operating personnel healthy had to certain harm.

Utility model content

The purpose of this utility model is to provide a kind of multilayer occluded air heat-insulating film, has solved heat-preservation cotton of the prior art by from great, not easy to operate, and has the problem of certain health hazard.

The technical scheme that the utility model adopts is, multilayer occluded air heat-insulating film, comprise fire-retardant film and the some layers of fire-retardant framework film that square is netted of some layers, fire-retardant framework film is clipped between each layer of fire-retardant film, and be fixed together with fire-retardant film, form at least 2 layers of rete by some sealing bubble continuous distributed, be fixed with fire resistant fabric layer in the outside of fire-retardant film.

Feature of the present utility model is also:

Wherein, fire-retardant framework film 2 is the netted structure of quadrangle, regular hexagon network structure or diamond-mesh structure.

Wherein, between fire-retardant framework film and fire-retardant film by together with being adhesively fixed, between fire-retardant film and fire resistant fabric layer by being adhesively fixed together.

Wherein, fire-retardant film is 3 layers, and fire-retardant framework film is 2 layers, and 2 layers of fire-retardant framework film are clipped between 3 layers of fire-retardant film 1, form 2 layers of rete by some sealing bubble continuous distributed.

Wherein, fire-retardant film is 4 layers, and fire-retardant framework film is 3 layers, and 3 layers of fire-retardant framework film are clipped between 4 layers of fire-retardant film, form 3 layers of rete by some sealing bubble continuous distributed.

The beneficial effects of the utility model are, solve existing heat-preservation cotton by from great, problem not easy to operate and unsoundness endangers, adopts the thin-film material of lightweight to make the rete of multi-layer sealed bubble continuous distributed, high insulating effect, and from heavy and light, can carry out as required cutting and piece together, easy to use, and there is the performance of fire protection flame retarding, both guarantee construction quality, also guaranteed the safety of construction.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.

The utility model multilayer occluded air heat-insulating film, as shown in Figure 1, comprise fire-retardant film 1 and the some layers of fire-retardant framework film 2 that square is netted of some layers, fire-retardant framework film 2 is clipped between each layer of fire-retardant film 1, and be fixed together with fire-retardant film, form at least 2 layers of rete by some sealing bubble 4 continuous distributed, be fixed with fire resistant fabric layer 3 in the outside of fire-retardant film 1.

Fire-retardant framework film 2 is regular hexagon network structure or diamond-mesh structure.

Between fire-retardant framework film 2 and fire-retardant film 1 by together with being adhesively fixed, between fire-retardant film 1 and fire resistant fabric layer 3 by being adhesively fixed together.

A kind of embodiment of the utility model multilayer occluded air heat-insulating film, as shown in Figure 2, fire-retardant film 1 is 3 layers, fire-retardant framework film 2 is 2 layers, 2 layers of fire-retardant framework film 2 of fire-retardant film are clipped between 3 layers of fire-retardant film 1, form 2 layers of rete by some sealing bubble 4 continuous distributed, and be fixedly pasted with fire resistant fabric layer 3 in the outside of the two-layer fire-retardant film 1 contacting with the external world.

The another kind of embodiment of the utility model multilayer occluded air heat-insulating film, as shown in Figure 3, fire-retardant film 1 is 4 layers, fire-retardant framework film 2 is 3 layers, 3 layers of fire-retardant framework film 2 of fire-retardant film are clipped between 4 layers of fire-retardant film 1, form 3 layers of rete by some sealing bubble 4 continuous distributed, and be fixedly pasted with fire resistant fabric layer 3 in the outside of the two-layer fire-retardant film contacting with the external world.

The utility model multilayer occluded air heat-insulating film, it mainly uses fire-retardant film and fire resistant fabric layer prepared by applied fireproofing to manufacture, between the fire-retardant film of some layers, accompany fire-retardant framework film, thereby can form some sealing bubbles between fire-retardant film and fire-retardant framework film, in sealing bubble, seal air up for safekeeping, thering is good heat preservation and insulation.Outside at fire-retardant film is pasted with fire resistant fabric layer, to increase toughness, when increasing the service life and strengthen heat insulation effect, also has the effect that strengthens fire protection flame retarding.The structure of fire-retardant framework film can be selected the netted structure of quadrangle, regular hexagon network structure or diamond-mesh structure, adopts quadrangle or diamond-mesh structure to have the simple feature of the mould of making, and the structural stability of horizontal cross-section is taken second place; And adopt regular hexagon network structure to there is the intrinsic stability of structure, on horizontal cross-section, respectively to stressed more balanced, but Mold Making is comparatively complicated.No matter adopt the network structure of which kind of form as framework film, do not affect the use function of the utility model heat-insulating film.

The utility model multilayer occluded air heat-insulating film, the coiled material that its manufactured goods are certain width, arbitrarily cutting splicing in use, adhesive tape bonding for stitching portion.Because weight per unit area is lighter, it is bonding that vertical structure insulation (as bridge pier, frame column etc.) can be carried out entirety parcel, simple to operate and can reuse, and reduces labor intensity greatly, has the effect of fire protection flame retarding simultaneously, guaranteed the safety of constructing.
