Description

A kind of inorganic composite heat-preserving plate and preparation method
Technical field
The invention belongs to construction materials and Material Field, specifically, are related to a kind of inorganic composite heat-preserving plate and preparation side Method.
Background technology
Building thermal insulation material 75% is the above are combustable organic material at present, such as EPS, XPS, PU etc..The section of these materials Can effect it is preferable, thermal conductivity factor is low, system application relative maturity, but shortcoming is also obvious, is mainly poor performance, cigarette during burning Mist is mostly big with smoke toxicity.
Inorganic heat insulation material also has application, such as rock wool, mineral wool, perlite etc. at present.These materials are A grades non-ignitable Material, though being not easy on fire, its poor thermal insulation property, water absorption rate are big, density is high, cost is also higher, and it is big to promote difficulty.
Current building thermal insulation material is in dilemma, organic insulation material good heat insulating, but poor performance.Inorganic guarantor Adiabator performance is good, but poor thermal insulation property.Recent years, the fire caused by thermal insulation material are therefore public into growth trend year by year Peace portion, house and town and country construction portion have all promulgated some files, and stringent regulation has been carried out for the performance of thermal insulation material.
Therefore, a kind of composite plate of good heat insulating how is provided as those skilled in the art's urgent problem.
The content of the invention
In view of this, the present invention provides a kind of inorganic composite heat-preserving plate, the coating face of the composite plate is using a variety of organic Material, inorganic material are mixed with, and can both achieve the purpose that heat preservation, and core selects hard-foam polyurethane plate, XPS extrusion moldings Plate, phenolic board and rock cotton board cover layer adhesion with the present invention, solve the composite plate of preparation and keep the temperature asking for difference in the prior art Topic.
To achieve these goals, the present invention adopts the following technical scheme that:
A kind of inorganic composite heat-preserving plate, including overlay and core plate, the formula of the overlay includes following parts by weight Raw material:40-50 parts of glass bead, 2-4 parts of mineral fibres, 4-8 parts of inorganic coagulation material, 4-8 parts of aerogel material, cement 25-35 parts, 8-12 parts of silicon ash, 2-3 parts of cellulose.
Preferably, the glass bead is dry density 100-110kg/m3, thermal conductivity factor 0.045-0.047W/ under room temperature (m·K)。
Preferably, the cement is 42.5 Portland cements.
Preferably, the silicon ash is 1200-1250 mesh numbers.
Preferably, the mineral fibres is 3-6mmPP staple fibers.
Preferably, the core plate is hard-foam polyurethane plate, XPS extruded sheets, phenolic board and rock cotton board.
Preferably, the core plate is preferably hard-foam polyurethane plate.
A kind of preparation method of inorganic composite heat-preserving plate, comprises the following steps:
1) each raw material is weighed by the formula of overlay in a kind of inorganic composite heat-preserving plate described above, then by each raw material Obtained dry blend is uniformly mixed, then dry blend and water are pressed 1:1.1-1.3 ratio is uniformly mixed to get batch mixing A;
2) the batch mixing A prepared in step 1) is uniformly paved with rapidly bottom portion of groove, thickness 10nm, then mechanization is put down Core plate is spread, is then uniformly paved with the batch mixing A prepared in step 1) on core plate again, then flattens compacting, thickness 50mm is wet to cut Required specification is cut into, last natural air drying 10-20min is to get inorganic composite heat-preserving plate.
Advantageous effect of the present invention:1) present invention in overlay be by with glass bead, mineral fibres, inorganic coagulation material, The mixing materials such as aerogel material, cement, silicon ash, cellulose process the thermal insulation material to be formed, rise it is high-efficiency insulated it is heat-insulated, moisture-proof, Increase intensity and protect core layer, the effect for isolating burning things which may cause a fire disaster;
2) overlay uses unsymmetric structure in the present invention:One of single side overlay is thick (hereinafter referred to as just for 10mm Face), another single side 50mm thickness (the hereinafter referred to as back side), the positive face paste wall in construction, even if can so ensure to run into because it is other because When plain (such as door and window, curtain, furniture, kitchen catch fire) generates fire, wall insulation system will not be grilled thoroughly, greatly increases safe system Number, further improves fire protecting performance;
3) present invention using unsymmetric structure reduces further production cost, and because catching fire in room when is mainly at metope Burning, so there is no need to especially thick overlay inside wall, but be further protection core plate, the intensity of plate is improved, The overlay for the one side for pasting wall is related to 10mm thickness;
4) present invention prepares the technique of inorganic composite heat-preserving plate, simple to operation, simplifies construction site because of thermal insulation material Material it is different and need the complicated processes of construction in layer, a variety of insulating products are integrated, can be implemented in production with standard, Solves the problems, such as the confusion in building supervision.
