The heat conduction coefficient (lambada) of the thin light waterproof composite heat-insulation thermal-insulation material for roofs is from 0.04 to 0.06 W/m. K, the application thickness is 20mm, and the load bearing per unit area is 4 kg/m<2>. The present invention has the advantages of favorable waterproof performance, long service life, fast and convenient construction, etc.
Description
The invention belongs to a kind of roof building material, be mainly used in the laying of house roof.
Existing roof building material generally uses materials such as boiler ash sediment, vermiculite, perlite products or foam concrete as insulating, and forms waterproofing course with the pitch hot pouring on insulating.The heat preservation and insulation of this class roof building material is relatively poor, and this mainly is that the coefficient of thermal conductivity of insulating is higher, is generally 0.087～0.15W/mK.In order to make it reach certain heat insulation and preservation effect, must increase the laying depth of insulating, their laying depth generally is 120～200 millimeters, therefore, their unit area load-bearing is also bigger, is generally 48～100kg/m
2This weight indicator is unfavorable for improving the shock resistance in house, simultaneously, can not adapt to the load-bearing requirement of wide span house cap.In addition, on the angle of construction, the carrying amount of material is big, time-consuming, and progress is slow.The water proofing property of above-mentioned roof building material is also relatively poor, and main cause is that the weather resisteant of this material waterproofing layer is good inadequately, and application life is shorter, is generally 3～5 years.The construction of waterproofing course is a heat construction in addition, and its poor stability, operation are also more numerous and diverse.Along with the develop rapidly of present builing industry, to the thin light of roof building material require and improve heat insulation, thermal-insulating waterproof performance demands and the easy construction rapidity requirement all urgent day by day.Yet up to now, the problems referred to above are not resolved yet in prior art.
The purpose of this invention is to provide a kind of thin light roof heat-proof insulation waterproof composite bed.To satisfy the requirement of builing industry to the thin light of roof building material, waterproof, heat insulation, insulation and convenient, fast construction.
Solution of the present invention is as follows: it has an insulating and the waterproofing course that is located on this insulating, described insulating is spliced by heat insulating board, and described heat insulating board constitutes (% by weight) by following material is compound: ceramic fibre 7～10% asbestos 25～32% float pearl 7～10% swell soils 15～20% polyvinyl alcohol 3～5% expanded perlites 25% rock wool 7～10% thickeners 0.3%; External surface at described heat insulating board is coated with the organosilicon curing compound that is useful on the reinforcement surface strength; Described waterproofing course is selected following a kind of: rubber and plastic modification (SEP) has composite waterproof coiled material; Polyvinyl chloride (PVC) waterproof roll; The cement water-proof layer that contains brokenly the glass fiber.Superiority of the present invention is as follows:
One, heat preservation and insulation of the present invention is better than existing roof building material greatly, the coefficient of thermal conductivity of its insulating is little, be coefficient of thermal conductivity λ=0.04～0.06W/mK, the higher limit of this coefficient of thermal conductivity than existing roof building material thermal conductivity institute lower limit also little 1/3rd.
Two, applied thickness of the present invention is thin, and promptly applied thickness is 20 millimeters, than 100～180 millimeters of the applied thickness attenuates of existing roof building material.Therefore, the present invention can be described as slim.
Three, of the present invention in light weight, its unit area load-bearing is 4kg/m
2About, and the unit area load-bearing of existing roof building material is 48～100kg/m
2Therefore, the present invention can be described as light-duty.
Four, water resistance is good, long service life.
Five, has economy.The present invention has under the condition of above-mentioned superiority, its cost cost and existing roof building material quite.
Six, cold construction is all adopted in construction of the present invention, simply, easily and fast, safety.
Describe making of the present invention and application in detail according to embodiment below.
The concrete consumption such as the following table of each material in the described heat insulating board:
| Sequence number | Title material | Weight (%) |
| 1 | Ceramic fibre | 8 |
| 2 | Asbestos | 30 |
| 3 | Float strain | 8 |
| 4 | Swell soil | 16.7 |
| 5 | Polyvinyl alcohol | 4 |
| 6 | Expanded perlite | 25 |
| 7 | Rock wool | 8 |
| 8 | Thickener | 0.3 |
Add up to 100%
The manufacture craft of this heat insulating board is: the water that adds 2.5～2.7 times of all material gross weights in the table in Da Chi, stir then, order adds material (1)～(8) in the table while stirring, and makes each material and water fully carry out chemical reaction in whipping process.After material and water fully react, just form the slurry material, this slurry material is put into mould dry, promptly form blank, at last coat the organosilicon curing compound at the external surface of blank, blank surface is hardened, and certain intensity is arranged, then make the finished product of heat insulating board.
In the employed composite material of heat insulating board, material (5) is a kind of low temperature thickener, is mainly used in the viscosity that improves the slurry material; Material (8) can be selected for use following a kind of: sodium phosphate trimer, polytetrafluoroethylene (PTFE), polyacrylamide, carboxymethyl cellulose and phosphoric acid mother liquor.Except that above-mentioned two materials, all the other materials all are heat insulating materials in the table.
Waterproofing course of the present invention is the best to use rubber and plastic modification (SEP) that composite waterproof coiled material is arranged, because this waterproof roll is the waterproof material that comes out in the recent period, its weather resisteant, oil resistivity, corrosion resistance are all fine, have ozone resistance and anti-flammability and good crack resistance and ageing resistance again.Its Applicable temperature is-50～100 ℃, and the southern north all can be used.Can reach 30～50 years its application life.Not only water resistance is good as waterproofing course with it, and can form good topping to insulating, thereby has improved greatly application life of the present invention.
In order further to reduce material cost, waterproofing course also can adopt described cement water-proof layer, and this waterproofing course is made up of sand, glass fiber and cement, and their amount ratio is 2: 3: 1.Owing to added glass fiber,, also have the characteristics of not firing in the above-mentioned waterproofing course so it has tension, bending resistance, intensity height, big, the impact-resistant advantage of toughness.But double as leveling layer also in work progress, thus working procedure reduced, further reduced cost.
Work progress of the present invention is:, as cementing agent the heat insulating board splicing is laid on the roofing with the slurry material of aforementioned heat insulating board, after the slurry material dried naturally, each heat insulating board was connected as a single entity, and formed an overall heat insulation insulation layer; Use rubber and plastic modification (SEP) cementing agent that described rubber and plastic modification (SEP) is had the composite waterproof coiled material lapped layup on insulating then, press seam at last, make this waterproof roll form the waterproofing course of an integral body.Can find out further that by above-mentioned work progress whole construction course is simple, all adopt cold construction, convenient and quick.
The present invention is through the aestivate field testing, consequently: use interior temperature of the present invention and reduce by 6～10 ℃ than the interior temperature of using existing roof building material.
