In view of above-mentioned, purpose of the present invention just provides that a kind of unit weight is light, easy construction, do not ftracture, the compound insulating material of cheap, high insulating effect.
The object of the present invention is achieved like this:
A kind of compound insulating material, it is the body of paste made from following weight proportion raw material and method:
White cotton 16-20 part sepiolite powder 25-35 part asbestos 35-45 part pearl 8-12 part perlite 45-55 part toughener 8-12 part binding agent 18-22 part of wafing.
Get the raw material of said ratio, add clear water earlier and stir into body of paste, mix water-resisting agent 1-3 part again.
The present invention is the thickness body of paste, and promptly slurry can directly be applied in body of wall, roofing and pipe surface, as the gentle roof heat insulation thermofin of building enclosure exterior wall insulating.Name of product of the present invention is the NPS compound insulating material.
The present invention has following advantage:
1. there is not the crack phenomenon of expanding with heat and contract with cold
Traditional various warming plates are after construction, and along with the variation of temperature, humidity, the crack that the easy appearance of seam crossing can't be made up not only influences attractive in appearancely, and has weakened heat insulation effect.The present invention directly spreads upon on the body of wall, and bonding is firm, and whole metope is an integral body, and its internal capillary reticulated structure has digested distortion, thereby surface of wall the crack can not occur.
2. insulation layer thickness is little
The thickness of the various warming plates of tradition generally more than 5cm, is added keel, gas cloud, and the thickness after its construction is about 8cm, has occupied bigger effective usable floor area.The whole insulation layer thickness of the present invention only is 2cm, has improved the usable floor area in room so virtually, has brought economic benefit to the developer.
3. there is not the dewfall of getting damp phenomenon
The tradition warming plate is met cold snap the dewfall phenomenon of getting damp can occur.Use the present invention, wall leveling does not have seam, and is good because of this material permeability, conduct heat evenly when meeting cold snap, so can not make the warm air formation dewfall of being obstructed in conductive process.
4. easy construction
Though the tradition warming plate has embodied standardized characteristics, needs auxiliary materials such as keel, cloth, metal guard strip during construction, and also wants operations such as assembly unit, bonding, filleting, construction is complicated.It is identical with conventional plastering technique that the present invention does when insulation, as long as smear smooth, hollowing not, just can not be out of shape, and it is easy to survive.
5. good in economic efficiency
For reaching the requirement of the Ministry of Construction energy-conservation 50%, if adopt the polyphenyl plasterboard, its thickness needs 10cm, and every square metre of labor and materials add up to and are about 130 yuan.And use the present invention, smearing thickness only needs 2cm, and every square metre of labor and materials total only is 42 yuan, reduces expenses more than two times.
6. nontoxic pollution-free, fire-resistant waterproof have economy and environment double benefit.
Thermal property of the present invention is through the on-the-spot test of physics Institute of Chinese Research Institute for Building Sciences, and the result is as follows:
The thermal resistance value of body of wall: R=0.712 (m
2K/W)
The resistance of heat transfer of body of wall: R
o=0.862 (m
2K/W)
Wall heat transfer coefficient: K=1.16 (W/m
2K)
The thermal resistance value of roofing: R=1.093 (m
2K/W)
The resistance of heat transfer of roofing: R
o=1.243 (m
2K/W)
Roofing heat transfer coefficient: K=0.80 (W/m
2K)
Estimate: change within the walls the surface at the abundant heart of 24cm and smear the thick NPS heat preservation slurry of 2cm, the Coefficient K of its body of wall=1.16 (W/m
2K).On roofing, smear the thick NPS heat preservation slurry of 5.5cm, the Coefficient K of its roofing=0.80 (W/m
2K), satisfy the requirement of " covil construction energy-saving design standard " JGJ26-95, just reduce the requirement of unit consumption of energy 50%.
Further specify below by embodiment.
Embodiment 1
Take by weighing raw material by following weight proportion: waft 18 parts of 8 parts of binding agents of 45 parts of tougheners of 8 parts of perlites of pearl of 35 parts in 25 parts of asbestos of white cotton 16 parts of sepiolite powders.
Put clear water in stirred vessel, in whipping process, add from cotton, asbestos, sepiolite powder, toughener, binding agent and perlite, the pearl of wafing successively, stir into the thickness body of paste.Each raw material stirring time is: white cotton 10 minutes, and asbestos 5 minutes, sepiolite powder 5 minutes, toughener 2 minutes, binding agent and perlite 5 minutes, the pearl 2 minutes of wafing.
Get during use and mix above-mentioned thickness body of paste after 1 part of water-resisting agent is converted the water dilution with 1: 6 ratio, promptly become working slurry.
In above-mentioned raw materials: sepiolite powder is to be obtained through pulverizing by sepiolite, sepiolite is a kind of mineral that originate in the rock seam of area, Yi County, Hebei province, light weight, has viscosity, the local common people are commonly used for foodstuff additive, sepiolite does not still have formal name used at school at present, and the present invention continues to use local title, and this title has obtained the identification of Hebei province's appropriate authority.The pearl of wafing is the bigger light granules of discharging from the steelworks chimney.Toughener is selected the magnesium powder for use, plays the joint filling enhancement.Binding agent is selected polyvinyl alcohol for use." the high temperature water-resisting agent " that water-resisting agent is produced for the chemical plant, Guangxi.The consumption of clear water is about 1.2-1.5 times of above-mentioned raw materials total amount.
Raw material of the present invention has light weight, ventilative, nontoxic pollution-free, fire-retardant character.
Embodiment 2
Take by weighing raw material by following weight proportion: waft 22 parts of 12 parts of binding agents of 55 parts of tougheners of 12 parts of perlites of pearl of 45 parts in 35 parts of asbestos of white cotton 20 parts of sepiolite powders.
Compound method is with embodiment 1.Get during use and mix above-mentioned thickness body of paste after 3 parts of water-resisting agents are converted the water dilution with 1: 6 ratio, promptly become working slurry.
