Technical field
The invention belongs to the refractory ceramic fibre material type, specifically is a kind of ceramic fiber backing warming plate.
Background technology
Traditional heat insulating inorganic fiberboard mainly contains: block of glass wool, rock wool heat-preservation plate, slag wool warming plate, mineral wool insulation and decoration absorbing ceiling, asbestos plate, aluminosilicate fiberboard and the fiberboard etc. that is mixed.
Traditional heat insulating inorganic fiberboard use temperature or below 600 ℃, such as: block of glass wool, rock wool heat-preservation plate, slag wool warming plate, mineral wool insulation and decoration absorbing ceiling, asbestos plate; More than 1000 ℃, such as the aluminosilicate fiberboard and the fiberboard that is mixed; At present, the heat insulating fiberboard that does not still have 600 ℃～1000 ℃ of use temperatures.Although some fibre enhanced composite heat insulation board is arranged, use temperature is in 600 ℃～1000 ℃ scopes, but owing to be not to be base material with the fiber, make that these material fragilities are big, easy efflorescence during use, for example: calcium silicate board fragility in the transportation use is big, and is damaged easily, and cause the efflorescence of calcium silicate board when using owing to high temperature burning mistake effect, thereby the intensity of losing.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency of the prior art, use temperature is in 600 ℃～1000 ℃ scopes, adopting ceramic fiber is that base material replaces fibrous magnesium silicate, and after adding one or more reinforcing fibres and adding part of auxiliary, and a kind of ceramic fiber backing warming plate that can increase substantially the thermal and insulating performance of thermal insulation thermal insulation board that makes.
The present invention is achieved by the following technical solutions:
It is a kind of ceramic fiber backing warming plate, with the pure aluminium silicate series fiber as base material, add one or more organic fibres or inorganic fibre and do fortifying fibre, and organic bond or inorganic bonding agent, filler and the additive of adding suitable proportion, make through batching slurrying, moulding, drying and following process operation, it is characterized in that it forms weight ratio is aluminum silicate fiber 50-85 part, organic fibre 1.5-3 part, 5～30 parts of ore deposit rock wools, 0～20 part of pearlstone, 5～20 parts of clays, 3～8 parts of starch, 0～1 part of polyacrylamide, 0.01～0.5 part of polymerize aluminum chloride.
It forms weight ratio further is aluminum silicate fiber 55-80 part, organic fibre 1.5-2.5 part, 7～25 parts of ore deposit rock wools, 2～17 parts of pearlstones, 5～16 parts of clays, 4～7 parts of starch, 0.2～0.8 part of polyacrylamide, 0.03～0.4 part of polymerize aluminum chloride.
It forms weight ratio further is aluminum silicate fiber 60-75 part, organic fibre 1.8-2.1 part, 9～19 parts of ore deposit rock wools, 5～15 parts of pearlstones, 7～13 parts of clays, 5～6.5 parts of starch, 0.4～0.7 part of polyacrylamide, 0.1～0.3 part of polymerize aluminum chloride.
The present invention adopts to such an extent that fortifying fibre is one or more organic fibres or inorganic fibre, improves the intensity of product of the present invention and reduces cost with this.Organic fibre is meant a kind of or compound use in the fiber kinds such as disregard message paper, ramie yarn, polyvinyl alcohol fiber, polyethylene fibre; Inorganic fibre is meant a kind of or compound use in the fiber kinds such as rock wool, slag wool, glass fibre.
