Description
Technical field
The invention belongs to building heat preservation field, a kind of vacuum thermal insulation plate and its manufacturing method are referred in particular to.
Background technique
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 easy to be scraped off in the construction process, hollowing, gas leak phenomenon occur, utilization rate substantially reduces.
It has existed in the prior art and coats low alkali adhesive mortar, foamed cement, inorganic guarantor outside vacuum thermal insulation plate
Warm mortar, modified cement and polystyrene particle, and above-mentioned technology our company has applied for a patent and has been protected.But above-mentioned technology
There are the problems such as at high cost, heat resistance is not high.
The present invention provides a kind of new substitute of above-mentioned technology, structure of the invention rationally, answering with external protection
Vacuum thermal insulation plate to be closed, solves the problems, such as vacuum thermal insulation plate breakage gas leakage in work progress, construction and installation are convenient,
Have the characteristics that excellent heat insulating ability, safety, durability and lightweight are ultra-thin, and is convenient for the industrial metaplasia of vacuum thermal insulation plate
It produces.
Summary of the invention
In order to solve the problem of that the scratch in operation of STP evacuated panel influences heat insulation effect, we are in STP evacuated panel
Surface covers one layer of Cement fibre felt, enables to STP evacuated panel high temperature resistant, and the high temperature damage of STP evacuated panel can be effectively prevented
It is bad.
The technical solution adopted by the present invention is as follows: a kind of composite evacuated heat insulating thermal preserving board of Cement fibre felt, the vacuum
Heat insulating thermal preserving board includes core material and the high-intensitive gas barrier film with protective layer, the high-intensitive gas barrier film packet with protective layer
It is rolled in the periphery of core material, and by vacuumizing encapsulation between core material；The high-intensitive gas barrier film with protective layer is by outer
The protective layer of side and the sealant of inside are combined；Wherein, protective layer is Cement fibre felt；Sealant by non-woven fabrics, aluminium foil,
Aluminizer, nylon film, polyethylene film, polyvinyl chloride film, polystyrene film, polyvinylidene chloride, gathers polyester film
Alcohol film, ethylene-acetate ethylene copolymer film, ethylene-vinyl alcohol copolymer film, polycarbonate film, polypropylene
One or more be combined.
Preferably, the Cement fibre felt is uniformly impregnated with by mixed slurry in entire fibrofelt, and repressed, baking
It is made after dry and maintenance；
The mixed slurry includes the component of following mass parts: 40-50 parts of cement, 30-45 parts of quartz sand, and coarse whiting 8-
15 parts, 5-10 parts of rubber powder, 0.1-3 parts of additive, 0.2-0.4 parts of water-reducing agent, 0.4-0.8 parts of retarder, each raw material is filled
Point be mixed to get.
Preferably, the cement uses portland cement, aluminate cement, sulphate aluminium cement, ferrous aluminate water
The mixture that one or more of mud, magnesia cement, high strength gypsum form in any proportion.
Preferably, the particle size of the quartz sand is 30-50 mesh or 50-80 mesh, appearance is round and smooth, without corner angle.
Preferably, the additive is polypropylene fibre, tartaric acid, hydroxypropyl methyl cellulose, lignin and gathers
The mixture obtained after one or more combinations in any proportion of vinyl alcohol.
Preferably, the water-reducing agent is lignosulfonates or sulfonated melamine compound resin.
Preferably, the retarder be monohydric alcohol, polyalcohol, polyvinyl alcohol, carboxylate group organic matter, tartaric acid,
Any one in phosphate or borate.
Preferably, the fibrofelt is one of glass fibre, ceramic fibre, polyester fiber or more than one are multiple
It closes.
A kind of preparation method of the composite evacuated heat insulating thermal preserving board of the felt of Cement fibre as elucidated before, comprising the following steps:
(1) tile the sealant, then takes the mold of specification pressed thereon, divides the mixing slurry of one layer of 1-5mm thickness
Material covers mixed slurry by the sealant in mold, forms transition adhesive layer, is then placed in Cement fibre felt, suppresses 8-24
H, it is demoulded after drying 6-24 h, forms the high-intensitive gas barrier film for having protective layer；
(2) the high-intensitive gas barrier film with protective layer described in is wrapped in the periphery of core material, and passes through pumping between core material
Vacuum Package forms the composite evacuated heat insulating thermal preserving board of Cement fibre felt with protective layer.
The beneficial effects of the present invention are:
1) the present invention provides a kind of structurally reasonable composite evacuated heat insulating thermal preserving board with external protection, mesh is substituted
Preceding insulation board in the prior art, solve the problems, such as in work progress vacuum thermal insulation plate because of damaged gas leakage, there is hollowing,
Construction efficiency is influenced, this composite plate has better resistance to pressure, crash resistance, and light weight, this composite plate construction and installation is convenient,
Utilization rate greatly improves；
2) Cement fibre felt can effectively be obstructed high temperature heat source as wall material to contact with the direct of STP evacuated panel, solved
STP evacuated panel the problem of wall material is more easily damaged under high temperature environment；
3) preparation step of composite evacuated heat insulating thermal preserving board improves.It is in the vacuum thermal insulation plate made before
On the basis of, coat external protection.The present invention is then first to prepare the high-intensitive gas barrier film with external protection, is then prepared again true
Empty heat insulating thermal preserving board.This have the advantage that operating procedure is simplified, make it possible large-scale production, makes Cement fibre felt
Composite evacuated heat insulating thermal preserving board is convenient for integrated molding.
Specific embodiment
A kind of composite evacuated heat insulating thermal preserving board of Cement fibre felt, the vacuum thermal insulation plate include core material and have anti-
The high-intensitive gas barrier film of sheath, the high-intensitive gas barrier film with protective layer are wrapped in the periphery of core material, and with core material it
Between by vacuumizing encapsulation；The high-intensitive gas barrier film with protective layer is answered by the protective layer in outside and the sealant of inside
It closes；Wherein, protective layer 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, ethylene-vinyl acetate
Copolymer film, ethylene-vinyl alcohol copolymer film, polycarbonate film, polyacrylic one or more are combined.
The present invention and existing low alkali adhesive mortar, foamed cement, inorganic heat insulation mortar, modified cement and polystyrene particle cladding
The prior arts such as object are compared, and can be improved about 18% crushing resistance, and because protective layer and sealant are taken out again after being integrally formed
Vacuum has lighter weight so that will form certain space between core material and gas barrier film, therefore compared with the existing technology
Amount, can reduce by about 16% or so weight, simultaneously as fibre cement felt, so that insulation board is with higher resistant to bending strong
Degree, can be improved about 12% intensity resistant to bending.Thermal insulation property of the invention simultaneously can improve 47% left side compared with the existing technology
It is right.
