Description of the invention: [Technical field to which the invention pertains] The present invention relates to a calcium silicate board, and more particularly to a lining acid board which uses one of the waste liquids as a raw material. The present invention also relates to a method for preparing the aspartic acid dance board, and a composition comprising the waste liquid crystal glass frit for preparing the stone plate. [Prior Art] It is known that calcium silicate board is good for installation and surface decoration, and has good properties of fire prevention 14, moisture resistance, durability, weather resistance, heat insulation, etc., while its billimeter is light and the deformation rate is low. Therefore, it is particularly suitable for use as a wall panel and roof for P or exterior slabs in buildings. It has become a widely used building board. The calcium silicate board is mainly made up of about 30~45 wt% of calcareous material (magic, lime, cement, etc.), about 3〇~45 wt% of tannin material (such as Shiyang powder, diatomaceous earth, etc.)矽 矽 acid material), and about 5 to b wt% of reinforcing fibers (such as pulp fibers, glass fibers, etc., used to enhance = structure) and 10 to 20 wt% of other mixed materials [which means in addition to "lime shellfish" “Materials”, “Shixi Acid Materials” and “Additional Materials for “Reinforcing Fibers” are selectively used as needed; other mixed materials commonly used in the industry are stone and paste (eg dihydrate gypsum, hemihydrate gypsum, Anhydrite gypsum), stone powder (carbonated dance powder), tackifier, aggregate, kaolin clay, montmorillonite clay, bentonite, recovered and crushed calcium silicate board powder, or these combinations It is mixed with water to form a first-class slurry, which is then formed into a mold box and obtained by a high pressure steaming treatment with a hot press pot. 200909378 Most of the above-mentioned tannins are derived from natural sandstone, but if the natural sandstone is over-exploited, it will seriously affect soil and water conservation and ecological balance. In addition, based on the gradual depletion of resources and the prohibition of laws and regulations, it also makes qualified grades of tannins. Materials are not easy to obtain. Therefore, 'the relevant industry is in urgent need of the substitute for the tannin material; in particular, 'if the tannin material can be provided by a waste, in addition to the environmental purpose of recycling the waste, Reduce the cost of the industry. Glass is a 100% recyclable material, and contains about 60% of NW2's should be used as the above-mentioned tannin material; however, the recycling source of waste glass is extremely wide and not fixed, resulting in recycling plants. The produced waste glass coupling can not maintain stable quality, and the higher alkali metal oxide content of the waste glass will produce "alkali_Aggregate Reacti〇n (AAR) for the hardened concrete, so that Waste glass can currently only be used in areas with low economic value, such as being added to asphalt or concrete as lightweight aggregates, followed by road paving works. The glass substrate is a necessary material for various panel manufacturing industries, and a large number of discarded glass substrates are also produced at the same time as the production of the panel, hereinafter referred to as "waste liquid crystal glass". At present, the subsequent treatment of the waste liquid crystal glass is carried out by landfill or simple and low-value recovery, for example, as a raw material for paving building materials, etc., and has no economic value; however, the advantage of the waste liquid crystal glass is that it contains an alkali metal oxide. The amount is low, and the source of waste liquid crystal glass is very consistent, so the quality of each batch is very stable. Therefore, it is speculated that the recycling of waste liquid crystal glass can not only improve its economic value, but also reduce costs and environmental protection. Many purposes. 200909378 [Summary of the Invention] The applicant of the present invention tried to replace the previously used raw material with waste liquid crystal glass powder, and as one of the raw materials for preparing the plate, and found that the obtained calcium silicate plate has the quality in accordance with national standards. It is obvious that the waste liquid crystal glass is used; 1 to replace each of the original ascorbic acid materials used in the conventional crushed (four) plate to prepare each of the plates. Therefore, the object of the present invention is to provide a preparation method for preparing a cesium strontium calcium plate using a composition containing waste liquid crystal glass powder suitable for preparing a chopped acid plate, and a preparation method from the preparation Method Calcium citrate plate. The composition containing waste liquid crystal glass powder provided by the purpose of this month includes 3 〇 to 45 Wt% of the yoghurt acid material, 30 to 45 Wt% of the calcareous material '5 丨 5 wt% of reinforcing fiber And other mixed materials of 1〇~2〇' are characterized in that the material material towel contains waste liquid crystal glass powder. In addition to the above, the composition is also allowed to contain other substances which do not affect the positive plate of the preparation, such as a small amount of water. The composition containing waste liquid crystal breaks can be further used to prepare a calcium silicate board, as follows. Another preparation method provided by the second object of the present invention is to prepare a calcium silicate board by using waste liquid S glass powder as one of raw materials. The method of the present invention comprises the steps of: (A) mixing the composition of the above-mentioned first object with water to form a slurry; (B) subjecting the slurry to a papermaking process to form a layered type of 200,909,378. After the preform, a high pressure steaming treatment and a drying treatment are sequentially performed to obtain the calcium silicate board. By applying the above-described preparation method of the second object of the present invention, the corresponding Shishi acid plate can be obtained to attain the third object of the present invention. The invention not only opens up a new application route for waste liquid crystal glass, but also achieves the purpose of low material cost, good efficacy and environmental protection appeal in the manufacture of calcium silicate board.
