Description
Technical field
The invention belongs to building heat preservation field, a kind of vacuum thermal insulation plate and its manufacture method are referred in particular to.
Background technology
Non-ignitable or fire retardant, the heat insulation effect although vacuum thermal insulation plate fire-protection rating common at present can be up to state standards
Well.But, they are easily scraped off in work progress, hollowing, gas leak phenomenon occur, and utilization rate is substantially reduced.
There is the low alkali adhesive mortar of vacuum thermal insulation plate outside cladding, foam cement, inorganic guarantor in the prior art
Warm mortar, modified cement and polystyrene particle, and above-mentioned technology our company applied for a patent and protected.But above-mentioned technology
There are problems that high cost, heat resistance not.
The invention provides a kind of substitute of new above-mentioned technology, rational in infrastructure, answering with external protection of the invention
Vacuum thermal insulation plate is closed, vacuum thermal insulation plate breakage gas leakage in work progress is solved the problems, such as, construction and installation are convenient, its
The characteristics of with excellent heat insulating ability, security, durability and ultra-thin lightweight, and it is easy to the industrial metaplasia of vacuum thermal insulation plate
Produce.
The content of the invention
The scratch in operation in order to solve STP evacuated panels, influences the problem of heat insulation effect, and we are in STP evacuated panels
Surface covers one layer of Cement fibre felt, enables to STP evacuated panel high temperature resistants, can effectively prevent the high temperature of STP evacuated panels from damaging
It is bad.
The technical scheme that the present invention takes is as follows：A kind of composite evacuated heat insulating thermal preserving board of Cement fibre felt, described vacuum
Heat insulating thermal preserving board includes core and the high intensity gas barrier film with overcoat, the described high intensity gas barrier film bag with overcoat
The periphery of core is rolled in, and by vacuumizing encapsulation between core；The described high intensity gas barrier film with overcoat is by outer
The overcoat of side is composited with the sealant of inner side；Wherein, overcoat is Cement fibre felt；Sealant by non-woven fabrics, aluminium foil,
It is aluminizer, polyester film, nylon film, polyethylene film, polyvinyl chloride film, polystyrene film, polyvinylidene chloride, poly-
Alcohol film, ethene-acetate ethylene copolymer film, ethylene-vinyl alcohol copolymer film, polycarbonate film, polypropylene
One or more be composited.
Preferably, described Cement fibre felt is uniformly impregnated with whole fibrofelt by mixed slurry, and repressed, baking
It is made after dry and maintenance；
The mixed slurry includes the component of following mass parts：Cement 40-50 parts, quartz sand 30-45 parts, coarse whiting 8-15
Part, rubber powder 5-10 parts, additive 0.1-3 parts, water reducer 0.2-0.4 parts, retarder 0.4-0.8 parts, each raw material is fully mixed
Stirring is closed, is obtained final product.
Preferably, described cement uses portland cement, aluminate cement, sulphate aluminium cement, ferrous aluminate water
One or more mixtures for constituting in any proportion in mud, magnesia cement, high strength gypsum.
Preferably, the particle size of described quartz sand is 30-50 mesh or 50-80 mesh, outward appearance is round and smooth, without corner angle.
Preferably, described additive is polypropylene fibre, tartaric acid, hydroxypropyl methyl cellulose, lignin and gathers
The mixture that one or more of vinyl alcohol is obtained after combining in any proportion.
Preferably, described water reducer is lignosulfonates or sulfonated melamine compound resin.
Preferably, described retarder be monohydric alcohol, polyalcohol, polyvinyl alcohol, carboxylate group organic matter, tartaric acid,
Any one in phosphate or borate.
Preferably, described fibrofelt is answered for one or more in glass fibre, ceramic fibre, polyester fiber
Conjunction is formed.
A kind of preparation method of the composite evacuated heat insulating thermal preserving board of felt of Cement fibre as elucidated before, comprises the following steps：
（1）Tile the sealant, then take the mould pressure of specification and put thereon, divides the thick mixed slurries of one layer of 1-5mm,
Mixed slurry is covered the sealant in mould, form transition tack coat, be then placed in Cement fibre felt, compacting 8-24 h,
The demoulding after drying 6-24 h, forms the high intensity gas barrier film with overcoat；
（2）The described high intensity gas barrier film with overcoat is wrapped in the periphery of core, and by vacuumizing between core
Encapsulation, forms the composite evacuated heat insulating thermal preserving board of Cement fibre felt with overcoat.
The beneficial effects of the present invention are：
1）The invention provides a kind of composite evacuated heat insulating thermal preserving board rational in infrastructure, with external protection, substituted for existing at present
Have the warming plate in technology, solve the problems, such as in work progress vacuum thermal insulation plate because of damaged gas leakage, there is hollowing, influence
Efficiency of construction, this composite plate has more preferable resistance to pressure, crash resistance, and light weight, and this composite plate construction and installation is convenient, utilizes
Rate is greatly improved；
2）Cement fibre felt can effectively be intercepted the directly contact of high temperature heat source and STP evacuated panels as wall material, STP is solved true
The hollow plate problem that wall material is more easily damaged in high temperature environments；
3）The preparation process of composite evacuated heat insulating thermal preserving board is improved.It is before the base in the vacuum thermal insulation plate made
On plinth, external protection is coated.It is of the invention then be first to prepare the high intensity gas barrier film with external protection, it is exhausted that vacuum is then prepared again
Hot warming plate.This have the advantage that operating procedure is simplified, make it possible large-scale production, be combined Cement fibre felt
Vacuum thermal insulation plate is easy to be integrally formed.
Specific embodiment
A kind of composite evacuated heat insulating thermal preserving board of Cement fibre felt, described vacuum thermal insulation plate includes core and with anti-
The high intensity gas barrier film of sheath, the described high intensity gas barrier film with overcoat is wrapped in the periphery of core, and with core it
Between by vacuumizing encapsulation；The described high intensity gas barrier film with overcoat is answered by the overcoat in outside with the sealant of inner side
Conjunction is formed；Wherein, overcoat is Cement fibre felt；Sealant by non-woven fabrics, aluminium foil, aluminizer, polyester film, nylon film,
Polyethylene film, polyvinyl chloride film, polystyrene film, polyvinylidene chloride, polyvinyl alcohol film, ethene-vinyl acetate
Copolymer film, ethylene-vinyl alcohol copolymer film, polycarbonate film, polyacrylic one or more are composited.
It is of the invention to be coated with existing low alkali adhesive mortar, foam cement, inorganic heat insulation mortar, modified cement and polystyrene particle
The prior arts such as thing are compared, it is possible to increase about 18% crushing resistance, and because overcoat and sealant are taken out again after being integrally formed
Vacuum, hence in so that certain space can be formed between core and gas barrier film, therefore relative to prior art, with lighter weight
Amount, can reduce by about 16% or so weight, simultaneously as fibre cement felt so that warming plate has higher resistant to bending strong
