Patent Application with Complete Specification The following statement is a full description of this invention, including the best method of performing it 5 known to me. [ Title ] Structure and Production Method of Cement Board 10 [ Abstract] This invention describes the structure and its production method for a cement board. The structure of this cement board is formed by stirring the mixture of water, cement, expandable Polystyrene (EPS), polypropylene (PP) fiber, 15 and emulsion resin; which follows grouting, coagulating and mold release processes for shaping. The production includes a platform mixer for material preparation; a first carrier that carries and places the horizontal mold at the outlet of the platform mixer as the formation step; 20 the concrete is poured into the horizontal mold as the grouting procedure; initial setting is performed for the concrete to form into a cement board; after the completion of the initial setting the cement board is separated from the horizontal mold on the first carrier 1 as the mold release process; the cement board is then placed onto the second carrier and at the same time the first carrier returns to formation step; the second carrier is placed in the steam curing room to proceed 5 with curing; after curing the cement board is sent to the cutting area for cutting. By above, the structure of the cement board is enhanced to stronger which has the functions of fireproofing, sound insulating, and easy to be nailed by using standard nails or hooks without 10 fracture. [ Field of Technology] This invention is related to the structure and its production method of a cement board, which especially 15 describe the enhancement of the structure of this cement board. This invention enables the cement board to have the functions of fireproofing, sound insulating, and easy to be nailed by using standard nails or hooks without fracture. 20 [ Existing techniques] According to IPC patent no. B32B-013/02 "A process for producing a woody cement sound-insulating plank and the woody cement sound-insulating plank prepared by 2 the process", the production of conventional cement boards include the following manufacturing procedures: (i) Immerse the flake-shape wooden material in the water; 5 (ii) Remove the immersed wooden material and place it into a container. During stirring, sequentially add the surface-active agent, cement powder, and hardener to mix homogeneously; of the above during adding of the surface-active agent 10 and hardener, simultaneously adding appropriate amount of water; (iii) After initial setting of the mixture, stir and pour it into the mold and then pressurization for forming. 15 (iv) Pre-setting is done before or after mold release; and (v) Steam curing according to the situation and then oven-dry or air-dry. Although previously mentioned woody cement 20 sound-insulating plank can indeed achieve sound insulating performance, however it is not fireproofing; furthermore according to IPC patent no. E04C-002/04 "Fiber-cement/gypsum laminate composite building material" (Please refer to Figure 4), it must at least 3 include: a fiber cement board 90; and a gypsum board 91; the fiber cement board 90 is laid on the gypsum board 91 to form a individual laminate composite board 9, which conform to ASTM E119 specification with the 5 fire rating of at least 1 hour. Although the above has fireproofing performance, however it does not possess sound insulating function. Thus, both previously mentioned conventional cement boards do not concurrently possess both fireproofing and 10 sound insulating capabilities. In addition, if a nail is directly nailed onto the board, fracture is caused to the cement board. To avoid the fracture we need to use IPC patent no. E04D-003/365 "Improved nail structure used in fixing coated corrugated board (or Calcium Silicate 15 Board)" (Please refer to Figure 5). The nailing body 92 is composed of board 93, which the front end of the board 93 forms a sharp angle end 94. In addition, the middle part of the board 93 is installed with several crossed corresponding barbs 95. The rear end of the board 93 20 has a vertical fixed end 96; on the fixed end 96 there is a fixed surface and an impact surface 97. The impact surface corresponds to the firing pin of a nail gun. Thus for those two previously mentioned type of cement boards, not only can they concurrently possess the 4 functions of fireproofing and sound insulating, but also a special structured nail is to be used. Ordinary nails cannot be used. Therefore, conventional techniques are not suitable for practical requirements. 5 [Content of the invention] The main purpose of this invention is to solve the defects above, this invention can enhanced the structure of the cement board, and to enable the cement board 10 has the capabilities of fireproofing, sound insulating, and easy to be nailed by using standard nails or hooks without fracture. To achieve the above purpose, this invention is a cement board production method. The structure of the cement 15 board is the mixture of water, cement, polystyrene (EPS), polypropylene (PP) fiber, and emulsion resin; by stirring, grouting, coagulating and mold release processes for shaping. This method is sequentially done by adding water, self-curing materials, injection molding foam, 20 filling materials, and water-base structural materials into a platform mixer, and make them homogenized by stirring to form into concrete prior to grouting process; the horizontal mold on the first carrier is placed at the outlet of the platform mixer, and the concrete is poured 5 into the horizontal mold; and the first carrier along with the horizontal mold and concrete is placed in a warm house for initial setting, after the completion of initial setting the concrete in the horizontal mold become a 5 cement board; after mold release the cement board in the horizontal mold on the first carrier is placed onto the second carrier and the first carrier returns to formation step; the cement board on the second carrier is then placed to the steam curing room; after steam 10 curing the cement board is sent to cutting area to proceed with cutting procedure, which the second carrier returns to mold release step.
