Description
Technical field
The invention belongs to a kind of inorganic heat insulating fiber PLASTIC LAMINATED, belong to 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 national fundamental state policy tackling climate change, realize national economy sustainable development.Since Eleventh Five-Year Plan, at national energy-saving, reduce discharging under the promotion energetically of policy, China's Building Energy-saving Work is developed rapidly.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 the northern area of China almost all adopts the thin heat-insulation systems of plastering such as pasting styrofoam (EPS/XPS), spraying polyurethane, account for the more than 95% of engineering application quantity, the Building Energy-saving Work that these technology are China has been made outstanding contributions.
But because styrofoam (EPS/XPS), spraying polyurethane all belong to inflammable material, at ground external wall insulation projects such as Shanghai, Shenyang, frequently there is fire disaster accident, cause the leader's of State Council great attention, therefore can become the fresh target that insider studies by fp warming plate.
Asbestos are a kind of good thermostable heat-isolating materials, there is low price, the feature such as short texture, light specific gravity, once be widely used in manufacturing 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.In the situation that the application of asbestos is restricted, exploitation becomes the demand of relevant industries without asbestos high-temperature-resistant thermal-insulation plate.
At present, many asbestos-free inorganic fiber thermal insulation PLASTIC LAMINATED have been there is on the market, mainly by various fibers, electrodeless bonding agent, organic bond, a large amount of mineral fillers and additive form, the Chinese patent that for example application number is 200610155138.4 discloses a kind of without asbestos thermostable heat-isolating plate, by high-temperature fibre, mineral filler and tackiness agent form, wherein the content of high-temperature fibre is 40%-80%, the content of mineral filler is 10%-50%, in a large amount of mineral fillers being added to without polar fibers when making, make sheet material, granulation frothing mold moulding again, spray mo(u)lding, foaming etc., this will certainly have influence on the thermal conductivity of filamentary material, cause thermal conductivity higher, and can cause refractory temperature low, as the high temperature resistant of the sheet material in this piece of patent application also only can reach 900 ℃.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.
