A kind of anti-skidding compound heat-insulation thin film
Technical field
This utility model relates to a kind of membrane structure, particularly to a kind of compound heat-insulation membrane structure with antiskid function.
Background technology
Thermal isolation film is also known as Obstruct membrane, heat insulation paper tinsel, reflectance coating; it is a kind of waterproof heat insulation thermal insulation film, uses metal aluminum foil as reflecting layer, be combined with density polyethylene film with high, polyester film, fabric, weaved film etc.; or MULTILAYER COMPOSITE, it is provided that protection and intensity, waterproof, heat-insulating property etc..
Insulating water-proof bed course is to be developed by thermal isolation film, and thermal isolation film is aerospace material the earliest, is mainly used in the external sheath of artificial satellite, intercepts the damage to satellite of the outer space strong ultraviolet with this.Last century the eighties, first the U.S. use it for building energy conservation.Nineteen ninety-five enters China, and name of product at that time is just pellicle space.In the use of China, it is concentrated mainly on Yangtze River Delta Region, at this less than in the vicennial time, adds up to use the roofing area more than 200 ten thousand square metres of this material, construction area more than 1,000 ten thousand square metres.The wherein thermal isolation film as pure heat-insulation and heat-preservation function and the insulating water-proof bed course as heat-insulation and heat-preservation Yu waterproof two kinds of functions, the about two points world.
Heat transfer shows as three kinds of modes in building heat exchanges: conduction of heat, thermal convection current, heat radiation.
After tile roofing temperature rising in summer, a large amount of radiant heat enter indoor and cause constant temperature to rise, and work is with living environment like a hen on a hot girdle.Insulating pad layer plays heat-reflecting effect, reduces thermal-radiating impact, is widely used in the heat-insulation and heat-preservation of roofing and body of wall.
The major function of insulating pad layer has:
(1) excellent heat insulating effect, reflectance is up to 90%, and it, through design and installation, constitutes antiradiation heat-insulation system with air space (or other conduction heat insulation material), can effectively reduce the generation of heat radiation, conduction of heat and thermal convection current, thus reach preferable heat preservation and energy conservation effects.
(2) good humidity resistance, product can effectively stop the infiltration of steam;In pitched roof engineering, play waterproof effect, in the construction of steel structural roof, can use as vapour-binding film.
Thermal isolation film has been widely applied in the middle of various types of roofing wall system, container stockpile heat-insulation system.But thermal isolation film present on market is the simplest compound at present, does not possess antiskid function, so during roofing, wall construction, it is easy to there is film and contact surface slides, easily bring potential danger to workmen, have much room for improvement.
Utility model content
The purpose of this utility model, is to provide a kind of anti-skidding compound heat-insulation thin film, and it has the most heat insulation and skidproof effect, and usage safety performance is high.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of anti-skidding compound heat-insulation thin film, including base layer bonded to each other and coating, wherein, coating uses aluminium foil or aluminizer, and base layer includes the end face laminating of woven cloth and nonskid coating, described coating and woven cloth, and the bottom surface of woven cloth coats nonskid coating.
The standard of above-mentioned aluminium foil or aluminizer is that weight per square meter is 30-100 gram.
Polypropylene, woven polyethylene cloth or the grid cloth that above-mentioned woven cloth uses weight per square meter to be 25-140 gram.
Above-mentioned coating and base layer use common plastics extrusion curtain coating laminating, PUR laminating or adhesive room temperature bonding mode to fit together.
Above-mentioned nonskid coating is to use non-slip elastomer curtain coating extrusion to be coated on the bottom surface of woven cloth.
Above-mentioned nonskid coating is to use coating roller coat to be coated on the bottom surface of woven cloth.
The thickness of above-mentioned anti-skidding laminated film is 0.05-0.25mm.
After using such scheme, this utility model, by increasing nonskid coating in the bottom surface of woven cloth, increases frictional force during compound heat-insulation film contacts, plays skidproof effect.So in work progress, the slip avoiding thin film with being covered by base material, reduce the security risk of construction, improve safety in utilization.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below with reference to accompanying drawing, the technical solution of the utility model is described in detail.
As shown in Figure 1, this utility model provides a kind of anti-skidding compound heat-insulation thin film, including base layer 1 bonded to each other and coating 2, wherein, aluminium foil that coating 2 can use weight per square meter to be 30-100 gram or aluminizer, and base layer 1 includes woven cloth 12 and nonskid coating 11, wherein, the polypropylene that woven cloth 12 can use weight per square meter to be 25-140 gram, woven polyethylene cloth or grid cloth, and nonskid coating 11 can use the mode of non-slip elastomer curtain coating extrusion or coating roller coat to be coated on the bottom surface of woven cloth 12, the end face of woven cloth 12 is fitted with coating 2, specifically can use common plastics extrusion curtain coating laminating, PUR laminating or adhesive room temperature bonding mode fit together.
This utility model gross thickness using above structure controls at 0.05-0.25mm.
Above example only illustrates technological thought of the present utility model; protection domain of the present utility model can not be limited with this; every according to the technological thought that the utility model proposes, any change done on the basis of technical scheme, within each falling within this utility model protection domain.
