Manufacturing method of sanding-free burning-resistant superfine fireproof plate

Abstract

The invention relates to a manufacturing method of a sanding-free burning-resistant superfine fireproof plate. The method comprises the sequential steps of: fireproof slurry stirring, molding and thickness fixing, demoulding, drying curing and trimming. The molding and thickness fixing step is mainly as below: placing a flat template on the bottom layer of a mold holder of the fireproof plate for to be molded, pouring the prepared fireproof slurry into the mold holder, accumulating a predetermined thickness on the surface of the template, covering a cladding layer on the upper edge of the fireproof slurry, applying vibration or rolling dynamic pressure on the upper edge of the cladding layer by a presser, so that the fireproof slurry firmly contacts with the template. Through the molding and thickness fixing step, the surface of the corresponding template is smooth after completion of the fireproof plate, and no additional sanding process is required, so as to enhance the manufacture efficiency and quality of the fireproof plate.

Description

technical field [0001] The invention relates to the field of fireproof building materials, in particular to a method for manufacturing a non-sanding flame-resistant super-grade fireproof board. Background technique [0002] Usually, most of the building materials used in the construction field are wood, but if a fire occurs, wood will help to burn, making wood not a good building material. Therefore, the current building materials used in construction have tended to use fireproof building materials, in addition to reducing the use of natural resources. In addition, it also avoids the occurrence of fire. [0003] Known from the prior art, there are two types of refractory building materials manufacturing methods, one is flow type, the finished product is continuous form, the other is frame mode, the finished product is one frame, one frame form. As for the product type, calcium silicate board is more common at present. Calcium silicate board is made of quartz powder, diatoma...

Problems solved by technology

[0004] The above three commonly used techniques to complete the finished fireproof board have a disadvantage, that is, the outer surface is rough, or even uneven. Whether it is for compartments or decorations, the appearance is poor, and it is necessary to apply additional coatings to the rough and uneven board surface. Using soil filling and sanding operations, or using sanding methods to control the thickness of the board, not only increases the manufacturing time and labor costs, but also the quality of the surface smoothness is poor, so it is necessary to improve it

The flame resistance effect of the fireproof board achieved by the above three commonly used technologies is not the best, and there is still room for strengthening
