Description
Technical field
The present invention relates to a kind of skin fire-type heat insulating board, more specifically to a kind of coal ash fiber exterior wall heat insulating board and preparation method thereof.
Background technology
Along with the aggravation of world energy sources crisis and the further deterioration of ecotope; Contradiction between China's energy and the environmental protection is more outstanding because of rapid economic development, and the heat preservation energy-saving of buildings has caused showing great attention in the industry to the positive influence of the deficient gradually energy and the ecotope that goes from bad to worse.Further standard and formulation and the enforcement of State Council along with the energy-saving design in construction requirement to relevant building energy conservation regulations; People have proposed increasingly high requirement to New Building Materials and wall thermal insulating system, and the energy-saving building materials of adiabatic heat-insulation, fire protection flame retarding, environmental protection has become the important subject of aspects such as social economy's Sustainable development, comprehensive utilization of resources, ecological environmental protection.
Exterior-wall heat insulation is as a kind of important building heat preservation technology; It is good to have heat preservation and energy conservation effects; Do not take indoor living space; Be convenient to buildings carried out characteristics such as decoration renovation, therefore in new building heat preservation energy-saving and existing building reducing energy consumption, have consequence, and in External Walls Heating Insulation, be used widely.The general traditional building materials such as air-entrained concrete building block, cement hollow building blocks, stove slag holllow building block and cement, gypsum hollow lath that adopt of at present domestic skin, heat insulation effect is poor more.And the general organic polymer cystoses that use of existing wall thermal insulation technology more; Like macromolecular material or thermal insulation mortar materials such as polystyrene foam plate, extruded polystyrene cystose, adhesive polystyrene cystoses; And that takes usually that insulating and facing protective layer combine is composite structured, has all obtained heat insulation effect preferably.But in practice is used; Though this type sheet material uses the focus with light weight, good heat insulating as external-wall heat-insulation material; Can also there be a lot of defectives simultaneously: poor like fire protection flame retarding property, do not reach the requirement of A level, when running into naked light, burn easily; And after burning, can produce toxic and harmful, hazardness is bigger.Therefore under existing exterior wall heat-preserving system system, the Green environmental-protection building material of exploitation safety performance height, fire protection flame retarding, heat-insulation and heat-preservation is significant.
Patent documentation CN101691801A discloses a kind of integrative external wall heat insulating decorative board for inorganic cotton metal finish and preparation method thereof; Main rock wool, mineral wool, glass wool or the aluminium silicate wool of adopting is as the warming plate base material; Adopt Tai-Ace S 150, phosphagel phosphaljel and calcium stearate as sticker, cost is higher.
Patent documentation CN101767974A has related to a kind of mineral-modified organic heat-insulating granules fireproof plate; With being pressed into fireproof heated board after mineral binder bond, auxiliary agent and granular polystyrene or the polyurethane particles mixing; Its fire resistance reaches national fire-retardant material A grade standard, but its ultimate compression strength is not high.
Patent documentation CN101428999A provide a kind of absorb low and medium frequency sound contain diatomaceous dalle of porous and preparation method thereof; Contain zeyssatite 70～80wt%, gypsum 18～25wt% in the sheet material; Though this sheet material can be used for fireproof heat insulating, heat insulation and acoustic absorption, volume density is still bigger.
Patent documentation CN101497216A discloses a kind of working method of light mineral wool slab; Particles of perlite is added in the mineral wool board; Further reduce the volume density of mineral wool board, but more in the sheet material of preparation because of powder particle, cause the mechanical property (like folding strength) of mineral wool board to descend.
Patent documentation CN86104350A provides a kind of method of manufacture of mineral fibreboard; Copying the slurry method with continuous wet type mixes mineral fibres such as asbestos and slag wool with waste paper that contains vegetable fibre or paper pulp; Add starch then as tackiness agent, the sheet material that makes is mainly used in indoor acoustic board.Yet utilize asbestos as base material in this method, bigger to human hazardness; Mouldy with starch as the easy moisture absorption of tackiness agent, influence its decorative effect.
Patent documentation CN1385388A has related to a kind of ceramic fiber warming plate and method for making thereof; Sheet material mainly is made up of ceramic fiber 40～60wt%, inorganic adhesive 20～30wt%, organic bond 0.5～1.5wt% and additive 20～30wt%; Be base material with the ceramic fiber in this sheet material, fibre content is less, and the inorganic bond agent content is more; Though the mechanical property of this ceramic beaverboard and heat-insulating property are high, volume density is still bigger.
Patent documentation CN101250039A has related to a kind of technology of preparing of coal ash fiberboard material; Make base material with coal ash fiber; With acrylic emulsions as sticker; Adopt the method for compression moulding and heat drying to prepare light weight, good heat insulation effect coal ash fiberboard material, but ultimate compression strength is not high.
At present; The most frequently used external wall insulation is rock cotton board, mineral wool board or calcium silicate board with microporous on the market; They are base material with rock wool, mineral wool or other vitreous fibre mainly, add sticker and other additive, copy to get and push or spray glue through wet method to be pressed into wet base; The base drying and moulding that will wet then is after deep processing becomes sound absorption warming plate or the fireproof heated board with decoration functions after handling.Though this type fireproof heated board fireproof insulation effect is relatively good,, it is applied received very big restriction because price is high or volume density is big.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of light weight is provided, fire retardant performance is good, heat insulation effect is good, the equal coal ash fiber exterior wall heat insulating board and preparation method thereof preferably of acoustically effective.
