A method of making fireproof board by using straw and fly ash

Abstract

The invention discloses a method for preparing a fireproof board by utilizing straw and fly ash. The method comprises the following steps on the whole: crushing the straw, performing presoaking and removing precipitated sand, performing thread rolling, preparing materials, performing pulp grinding, removing residues and performing screening, performing conventional papermaking, performing soakingin glue, performing drying and performing cutting, placing glue-soaked paper, pressing a board and taking down the board, sawing waste edges and performing sanding, and performing inspection and performing packaging. The method provided by the invention utilizes the cotton straw and the fly ash for pulping, so that resource recycling can be realized, and the environmental pollution problem causedby straw burning and the fly ash can be solved; fibers are swelled and softened after fully absorbing and adsorbing the fly ash to obtain good pulp required for papermaking through mechanical pressureand temperature action; and a shortage of physical indexes of base paper is compensated through chemical engineering control, and high quality fireproof board impregnated base paper is further prepared.

Description

technical field [0001] The invention relates to a method for manufacturing a fireproof board, in particular to a method for manufacturing a fireproof board by utilizing straw and fly ash. Background technique [0002] Fireproof board, also known as anti-fold special board, is made of decorative colored paper impregnated with melamine resin, plus multiple layers of black or brown kraft paper impregnated with phenolic resin, and then pressed with a steel plate under high temperature (150°C) and high pressure (1430psi) environment. , the thickness can be made from 1.6mm to 25mm. It is a high-pressure decorative board with a transparent structure. The colored paper layer on the surface can not only meet a variety of color choices, but also provide "glossy surface, pearl suede surface, micro star surface, diamond pattern, square pattern, snow Meteor, matte, embossed, brushed metal" decoration needs. Therefore, fireproof panels are widely used in furniture, cabinets, interior de...

Problems solved by technology

[0003] At present, the demand for fireproof panels at home and abroad is very large. Although the global production is also increasing at an annual capacity of more than 20%, it still cannot meet the increasing demand for use. Therefore, the research and development of new manufacturing processes is very important for promoting the rapid development of social economy. of great significance
