Abstract
The invention discloses a non-asbestos fiber reinforced calcium silicate board and a manufacturing method thereof. The non-asbestos fiber reinforced calcium silicate board comprises the following components in percentage by weight: 15-25 percent of ceramic waste powder, 35-40 percent of cement, 20-30 percent of powdered quartz, 8-10 percent of quick lime, 7-10 percent of organic fiber, 1-2 percent of inorganic thickening agent and 0.5-1 percent of antifoaming agent. After the technical scheme is adopted, the non-asbestos fiber reinforced calcium silicate board and the manufacturing method thereof have the greatest advantages that the rigidity of the board is improved by taking glaze-containing dust (ceramic working waste), produced by grinding during polishing of ceramic veneer, as filler to participate in hydration reaction of the board, the mechanical property of the board is reinforced, so that the mechanical property of a board containing asbestos fiber is achieved.
Description
Technical field
The present invention relates to the technical field of building board, be meant that specifically a kind of non-asbestos fiber strengthens calcium silicate board and preparation method thereof.
Background technology
It is the inside and outside wallboard that the Ministry of Construction applies that non-asbestos fiber strengthens calcium silicate board.Convention in the industry; The wallboard that contains fibrous magnesium silicate (carcinogens) use that is under an embargo from June 1st, 2011; And non-asbestos fiber enhancing calcium silicate board (hereinafter to be referred as sheet material) adopts organic fibre owing to not containing fibrous magnesium silicate, and the rigidity that must strengthen sheet material just can remedy the intensity that it does not contain fibrous magnesium silicate.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide a kind of and utilize ceramic veneer when polishing to grind the glaze dust (waste material of Production of Ceramics process) that contains that produces to strengthen calcium silicate board and preparation method thereof with the non-asbestos fiber that improves its mechanical property as the rigidity stopping composition.
For realizing above-mentioned purpose; Each composition that its non-asbestos fiber of technical scheme provided by the present invention strengthens calcium silicate board is by following weight percent proportioning: the useless powder 15～25% of pottery, cement 35～40%, konilite 20～30%; Unslaked lime 8～10%; Organic fibre 7～10%, inorganic thickening agent 1～2%, skimmer 0.5～1%.
The major ingredient of the useless powder of said pottery is AI

267-70%, Fe
2O
31%, K
2O 6-8% and colorant.
Said konilite is 200 order konilites.
Said inorganic thickening agent is a wilkinite.
The making method that non-asbestos fiber according to the invention strengthens calcium silicate board is following:
1) the component proportioning that, described non-asbestos fiber is strengthened calcium silicate board adds 75%～80% water and processes and contain solid-state 25～28% slip; At first the organic fibre water is mixed; Under whipped state, add unslaked lime, cement, the useless powder of pottery, konilite, inorganic thickening agent then; Wherein, Unslaked lime was given water cure earlier and is handled before feeding intake, can produce bubble at pulping process because organic fibre reacts, so add skimmer to stablize slip;
2), with above-mentioned 1) in the slip that obtains inject laminator and process the soft board embryo through 60 ℃ ± 2 ℃ warm and humid maintenances, under the condition of 175～185 ℃ of 0.8～1Mpa pressure and temperature, process hard plate material then through 8 hours hydration reaction.
The hard plate material of processing is at density 1.1g/cm
3State under, the folding strength>=10Mpa of its oven-dried condition meets the using strength of sheet material fully.
The present invention is after adopting above technical scheme; Its great advantage is that the present invention grinds the glaze dust (potter makes waste) that contains that produces to make the hydration reaction that stopping composition is participated in sheet material when utilizing the ceramic veneer polishing; Improve the rigidity of sheet material; To strengthen its mechanical property, make it reach the mechanical property of the sheet material that contains fibrous magnesium silicate.
Embodiment
Below in conjunction with specific embodiment the present invention is further specified.
