Description

The inorganic fibre fireproof heated board
Technical field
The invention belongs to a kind of inorganic heat insulating fiber PLASTIC LAMINATED, belong to the energy-saving building materials field.
Background technology
Building energy conservation is an important component part of save energy.Carrying out building energy conservation is a fundamental state policy of country's reply climate change, realization national economy sustainable development.Since Eleventh Five-Year Plan, under the big force urges of national energy-saving and emission-reduction policy, China's building energy conservation work has obtained fast development.Up to the present, more than 17 hundred million square metres of energy saving buildings have been totaled.The exterior wall of these newly-built energy saving buildings and existing building reducing energy consumption mainly adopts External Thermal Insulation Technology for External; Particularly north China almost all adopts the thin heat-insulation systems of plastering such as pasting styrofoam (EPS/XPS), spraying polyurethane; Account for more than 95% of practical applications amount, these technology have been made outstanding contributions for the building energy conservation work of China.
But owing to styrofoam (EPS/XPS), spraying polyurethane all belong to inflammable material; The fire disaster accident frequently takes place at ground exterior wall heat insulating works such as Shanghai, Shenyang; Cause the leader's of State Council great attention, therefore can become the fresh target that the insider studies by the fp warming plate.
Asbestos are a kind of good thermostable heat-isolating materials; Has low price; Characteristics such as short texture, light specific gravity once were widely used in making various insulations, heat insulation and high temperature material, but asbestos are comparatively serious to the harm of the pollution of environment and human body; Particularly the dust of dry state is very harmful to HUMAN HEALTH, thereby its application is restricted.Under the situation that the application of asbestos is restricted, develop the demand that no asbestos high-temperature-resistant thermal-insulation plate becomes relevant industries.
At present; Occurred many asbestos-free inorganic fiber thermal insulation PLASTIC LAMINATEDs on the market, mainly be made up of various fibers, electrodeless wedding agent, organic bond, a large amount of mineral filler and additive, for example application number is that 200610155138.4 Chinese patent discloses a kind of no asbestos thermostable heat-isolating plate; Form by high-temperature fibre, mineral filler and tackiness agent; Wherein the content of high-temperature fibre is 40%-80%, and the content of mineral filler is 10%-50%, a large amount of mineral fillers is added in the no polar fibers process sheet material; This will certainly have influence on the thermal conductivity of filamentary material; Cause thermal conductivity higher, and can cause refractory temperature low, also only can reach 900 ℃ like the high temperature resistant of the sheet material in this piece patented claim.But one skilled in the art will appreciate that if do not add mineral filler sheet material just can be very soft, physical strength is not high.
Summary of the invention
In order to solve the problems of the technologies described above, the object of the present invention is to provide a kind of thermal conductivity that does not influence fiber, high temperature resistant and inorganic fibre fireproof heated board that physical strength is high.
