Description

The color light heat-insulating roof board

Technical field

The utility model relates to a kind of roof covering, especially a kind of color light heat-insulating roof board.

Background technology

At present, existing insulating board has three kinds: a kind of is the built on stilts prefabricated C2 concrete of normal silicate cement board, and it utilizes circulation of air heat insulation, this insulating board makes the easy ponding of roofing, can not be paved with roofing, and the structure temperature influence is big, easy to crack leaking, protective value is poor, and coefficient of thermal conductivity is big, effect of heat insulation is poor, from great, and the constructional difficulties complexity, engineering quantity is big, shortcomings such as inconvenient maintenance, and built on stilts need certain height, increased the height and the expense of building; Another kind is cast-in-place expanded perlite concrete isolation layer, spreads one deck capping cement mortar more in the above, and heat-proof quality is also poor, and roof protecting layer is easy to crack, easily water inlet, and protective value is poor; The third is an extrusion molding foam-board, adopts the material heat-insulation and heat-preservation from waterproof, and is in light weight, but isolation layer and topping do not have tack coat, and hollowing damages easily, and protectiveness is poor.

The purpose of this utility model provides that a kind of to have a heat insulation and preservation effect good, in light weight, and surface layer is highly polished, and is attractive in appearance, durable, intensity is high, " color light heat-insulating roof board " easy for installation.

Technical solution adopted in the utility model is: be the double layer composite structure, i.e. high strength surface layer and thermal insulation bottom.That surface layer is designed to the plane or have groove.

Adopting surface layer that Portland cement or white cement or coloured cement, quartz sand or river sand, water and brightener make and be major ingredient, be auxiliary material with cinder, sawdust with the polystyrene foam material of low thermal conductivity, is gluing and the bottom formed of cement admixture with building glue, Portland cement.

Advantage of the present utility model:

1. good heat-insulation effect

Because the major ingredient of bottom has been selected the minimum polystyrene plastics foam of coefficient of thermal conductivity for use, can effectively stop the heat radiation of the sun, makes interior temperature comfortable pleasant.

2. in light weight

Isolation layer unit weight is 264 kilograms for every cube, and unit weight gently reduces building load, and is very favourable to the safety of structure, meets the requirement of aspect material lighting.

3. good looking appearance

Surface layer is white in color or is colored, and is highly polished, reflecting sun heat radiation effectively, and reflectivity reduces interior temperature effectively up to more than 90%.Outward appearance is beautiful, and surface layer is smooth, bright and clean plain, and corner angle are clearly demarcated, and neat appearance increases aspect color and artistic feeling, beautifies the environment.

4. compressive strength height

It is 200kpa that the compressive strength of general accessible roof requires, and compressive strength of the present utility model is 790kpa (detection data), and surface layer can reach anti-folding, the compressive strength of portland cement concrete plate, reaches the standard of accessible roof fully.

5. water resistance is good

Because product surface layer compactness height, the capillary porosity duct major part that is easy to seep water is cut off, and cooperates the mortar shop fixtures in work progress, again with waterproofing mortar or SC-K100 buildings waterproof gap-filling glue or the jointing of JCTA-300 jointing agent, surface layer has favorable waterproof property with regard to many one decks waterproof barrier.

6. energy-conservation profit is useless

The heat-insulation and heat-preservation layer material all adopts the waste polystyrene foam of recovery to be commonly called as " white garbage ", and energy-conservation profit is useless, environment purification.

7. easy construction can cut randomly, and mounting method is various, and is convenient and swift.

Fig. 2 is the cutaway view Amplified image of Fig. 1.

Fig. 3 has the structural representation of groove for the utility model surface.

The specific embodiment

The utility model is the double layer composite structure, i.e. high strength surface layer 1 and thermal insulation bottom 2.Adopting the surface layer of anti-folding that Portland cement or white cement or coloured cement, quartz sand or river sand, brightener and water makes, resistance to compression, best bright finish, high reflectance and be major ingredient, be auxiliary material with cinder, sawdust with the polystyrene foam particles of low thermal conductivity, is gluing and the thermal insulation bottom 2 formed of cement admixture with building glue, water, Portland cement.Surface layer and bottom unite two into one, once-forming.Surface layer can add the nano antifouling material, can prevent the pollution of plate face, plays the effect of surface layer cleaning.

Surface layer is designed to the plane, as Fig. 1, or with anti-skidding drain function groove, as Fig. 3.

Manufacturing process is as follows:

(1) prepares in proportion with Portland cement or white cement or coloured cement, quartz sand or river sand, brightener, water and put into mixer and stir, the lining that stirs is injected mould, keep the thickness of estimating.Start vibrating motor, vibrate the air of getting rid of in the material, strengthen the compactness of surface layer.

(2) cinder, sawdust, polystyrene foam particles, building glue, cement admixture, Portland cement, water are prepared in proportion put into mixer and stir, again bed material is injected and be equipped with in the mould of lining, vibrate bed material once more, roll-forming, quiet stopping solidified, and maintenance is dispatched from the factory.

The utility model integrates insulation, waterproof, decorates, and has easy construction, in light weight, joint The characteristics such as the energy profit is useless, environmental protection attractive in appearance.

Claims (3)

1, a kind of color light heat-insulating roof board is characterized in that: be the double layer composite structure, i.e. high strength surface layer (1) and thermal insulation bottom (2).

2, color light heat-insulating roof board according to claim 1 is characterized in that: that surface layer (1) is designed to the plane or have groove.

3, color light heat-insulating roof board according to claim 1 is characterized in that: surface layer (1) can add the nano antifouling material.
