A kind of high-efficiency insulated fireproof composite board with decoration effect
Technical field
The present invention relates to building material field, be specifically related to a kind of high-efficiency insulated fireproof composite board with decoration effect and preparation method.
Background technology
Building Energy-saving, is not only economic problems, and is important strategic issue. Building energy conservation is for promoting energy resources saving and rationally utilizing; accelerate development recycling economy; realize the sustainable development of economic society; build a conservation-minded society; having very important effect, is also an Important Action that ensures national energy security, protection of the environment, raising people quality of life, implement scientific view of development.
Exterior-wall heat insulation is to be worth applying in the world effective power-saving technology, nowadays exterior-wall heat insulation building has become American-European grade for the highest a kind of energy-saving building technology of developed country's occupation rate of market, and occupation rate in other markets, various countries, the world is also in rising year by year.
On market, Outwall thermal insulation board is mainly taking organic heat-insulating plate as main, although the warming plate heat-insulating property of this organic is good, but the fatal shortcoming of this class organic heat-insulating plate is exactly that its combustibility is high, although great majority have added fire retardant at present commercially available organic insulation material, have certain flame retardant effect, but flame retardant effect is not obvious. And there is the undesirable shortcoming of overall heat insulation effect in the inorganic heat-insulation board of selling on market.
Summary of the invention
First object of the present invention is to provide a kind of high-efficiency insulated fireproof composite board with decoration effect, comprises heat-insulation layer, fiber web layer and decorative layer.
Above-mentioned heat-insulation layer and decorative layer lay respectively at the both sides of fiber web layer, between them, fix by organic binder cemented.
Above-mentioned fiber web layer is glass fiber mesh, bamboo fibre net or wood fibre net.
Above-mentioned decorative layer is styrofoam, phenolic foam heat insulation plate or polyurethane foam insulation plate.
Above-mentioned organic bond is epoxy adhesive, polyurethane adhesive or phenolic resin adhesive.
Above-mentioned heat-insulation layer comprises the raw material of following weight portion: 15 ~ 30 parts of foam glass, 8 ~ 15 parts of ferrosilicon ground-slags, 12 ~ 15 parts of grey calcium powders, 15 ~ 25 parts, asbestos, 15 ~ 20 parts of wood fibres, 8 ~ 15 parts, magnesium powder, 3 ~ 6 parts of foaming agents, 3 ~ 8 parts of waterproofing agents, 15 ~ 25 parts of sawdust powder.
Above-mentioned grey calcium powder is 300 ~ 500 object ash calcium powders.
Above-mentioned foaming agent is OTAC, Cetyltrimethylammonium bromide or aluminium powder.
Above-mentioned waterproofing agent is calcium stearate, aluminum stearate or sodium methyl silicate.
Second object of the present invention is to provide a kind of preparation method of high-efficiency insulated fireproof composite board with decoration effect: by foam glass, ferrosilicon ground-slag, grey calcium powder, asbestos, wood fibre, magnesium powder, ripe rubber powder II, foaming agent, waterproofing agent, sawdust powder, mixes in proportion, puts into mixer and adds water and stir and mix; To absorb water paper washer at die surface, and gained mixture is poured extrusion forming in mould into; The raw material module obtaining after extrusion forming is sent in baking oven and is dried; Take out shaped heat insulation material, to be cooled completely after, by heat-insulation layer, fiber web layer and decorative layer by organic binder cemented fixing.
The raw mixture of above-mentioned making heat-insulation layer and the mass ratio of water are raw mixture: water=1:1.5 ~ 2.2.
Invention raw material are easily buied, and preparation method is simple, and sound insulation, heat insulation, heat preservation energy-saving and decorative effect are remarkable.
Detailed description of the invention:
Below in conjunction with concrete case study on implementation, the present invention is described in further detail.
