Description
Technical field
The present invention relates to building material field, be specifically related to a kind of external wall body thermal insulation decorative board and preparation method thereof.
Background technology
Building energy conservation and environmental protection are the key subjects of present face of mankind.In recent years, China has formulated " economizing energy law " in succession, " building law " a series of laws, rules such as " code for thermal design of civil buildings " are alleviated China's energy availability and demand contradiction, has promoted the development of building energy conservation cause.For single building, its energy-conservation door and window, exterior wall and roof heat insulation system of depending primarily on, wherein exterior wall will be born 50～60% of whole energy effect usually, so the quality of skin heat-insulation system is for realizing that the building energy-saving effect is most important.
The present unit building area heating of China is equivalent to 3～4 times of the close developed country of weather conditions with energy consumption; China is a country that the energy is barrenr; So reasonable energy utilization; Improving energy utilization rate is the task of paramount importance of Chinese society development, and the improvement of skin space enclosing structure power-saving technology, the renewal of heat insulating material has earth shaking meaning to the reduction of society and building energy consumption.At present China's architectural exterior-protecting construction power-saving technology is used maximum three kinds of forms that have: 1. external wall outer insulation; 2. exterior wall internal insulation: 3. sandwich heat preservation.Through finding behind the practical proof for many years that the advantage of the external wall outer insulation practice is the most remarkable, should become the developing direction of the principal mode and the energy saving building heat-preserving wall of China's wall thermal insulating.It is more that China is used for the energy-saving material kind of architectural exterior insulation, mainly contains: rock wool, polystyrol plastic foam plate, foam cement, polyphenyl plate etc.Current, the external wall heat insulation system of domestic popularization mainly contains the thin heat insulation system etc. of plastering of adhesive powder-polystyrene granule thermal insulation mortar, polyphenyl plate (comprising the extrusion molding type) and hard polyurethane foam.Although these systems have obtained better effects in applying, and improve perfectly constantly, the problem that exists is still many.Be that mainly especially durability enjoys query to the worry of crack, energy consumption (polyphenyl is the oil extract), safety and durability.
Now; Whole world heat preserving and insulating material just develops towards efficient, energy-conservation, frivolous, waterproof, decoration integrated direction, more should be widelyd popularize and use as a kind of novel heat preserving and insulating material and have the external wall outer insulation decorative panel of decorating with energy-conserving action simultaneously concurrently.Disclose a kind of outer wall heat insulating and decorating plate and manufacturing approach among the patent documentation CN 100398763C, but wherein still made insulation layer with polyphenyl plate, anti-flammability that it is whole and durability are still barely satisfactory.In addition, though there are some to make insulation layer, exist the moisture absorption in its goods, return halogen with the inorganic compounding material, serious mass defect such as scum, water resistance weatherability difference or heat-insulating property are not good.
Summary of the invention
The technical problem that the present invention will solve has provided the external wall body thermal insulation decorative board of a kind of nonhygroscopic, halogenation that integrates ornamental, energy saving, economy, convenience, scum, good weatherability, and discloses a kind of preparation method of external wall body thermal insulation decorative board.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
A kind of external wall body thermal insulation decorative board; Comprise finish coat; Be disposed with the magnesite bed of material, folder muscle layer and inorganic mixing insulation layer in this finish coat inboard; Said folder muscle layer is that thin bamboo strips used for weaving net, reed are slightd net, cornstalk crust and slight in the net any one, and said inorganic mixing insulation layer is filled by following inorganic compound and formed:
1.5～2.5 parts of 100～120 parts of the magnesium chloride brines of 100 parts of magnesia powders, Baume degrees 23～28,70～90 parts of medium sands, 120～130 parts of quartzs, 20～50 parts of glass beads, 4～8 parts of glass fiber, 1～2 part of alum, 13～14 parts of mica powders, 6～7 parts in flyash, OP-i01.5～2.5 part, modifier.
Between the said finish coat and the magnesite bed of material, also be provided with glass layer.
Said magnesite thickness of feed layer is 2～5mm.
Said folder muscle layer thickness is 1.5～3mm.
Degree is 35～45mm behind the said inorganic mixing insulation layer.
Said finish coat is provided with imitative layer of wood, or imitative metal-like layer, or the face brick-imitation layer.Employing mold technology, facing has abundant moulding, face brick-imitation, imitative wood, imitative stone material, imitative metal etc.
A kind of preparation method of external wall body thermal insulation decorative board may further comprise the steps:
(1) foundation forms is set, and lays polished film above that;
(2) coating magnesite grout on polished film; Form the magnesite bed of material of thickness 2～5mm, said grout forms (modifier that as required can add conventional requirement) by 1: 1～1.5 quality than hybrid modulation by the magnesium chloride brine of magnesia, 23～28 Baume degrees;
(3) on magnesite pulp layer upper berth if bonding folder muscle layer, said folder muscle layer is that thin bamboo strips used for weaving net or cornstalk crust are slightd net;
(4) on said folder muscle layer, lay inorganic mixing inserts, form inorganic mixing insulation layer; In weight portion, said inorganic mixing inserts is evenly mixed by following raw material: 1.5～2.5 parts of 100～120 parts of the magnesium chloride brines of 100 parts of magnesia powders, Baume degrees 23～28,70～90 parts of medium sands, 120～130 parts of quartzs, 20～50 parts of glass beads, 4～8 parts of glass fiber, 1～2 part of alum, 13～14 parts of mica powders, 6～7 parts in flyash, OP-101.5～2.5 part, modifier;
(5) vibratory compaction, rolling are smooth;
(6) under the condition of 25～30 ℃ of relative humidity 60～70%, temperature, maintenance demoulding after 1～3 day;
