Method of mineralizing plant fiber and its applications

Abstract

A method for mineralizing the plant fibers and using them to prepare building material includes such steps as preparing plant fibers from at least one of wood, palm fiber, coconut fiber, cotton stalk, bamboo, grass, nut shell and bean shell, preparing hardening agent by mixing solution with at least one of calcium carbonate, calcium chloride, calcium silicate, magnesium oxide, magnesium chloride, magnesium oxygen sulfate, zinc oxide, pearlite, carborundum and fluorspar, mixing it with said plant fibers, loading the mixture in mould, pressurizing, demoulding and solidifying.

Description

technical field [0001] The present invention relates to a method of mineralizing plant silk and its application, in particular to a plant silk made from a variety of plant materials, which is mixed with a hardening agent made of inorganic mineral materials and solutions to make plant silk The fiber is mineralized, and the mixture of the plant silk and the hardening agent is placed in the mold, pressurized to form building materials of various shapes, demolded, and solidified to form building materials of various shapes.

[0002] The usual process of wood wool resin boards is to cut wood into wood wool, mix it with glue or resin, gypsum, magnesia and other inorganic substances or cement, and finally press it into a board shape; it is different from traditional brick construction, etc. Compared with other construction methods, the construction is relatively simple, and has the advantages of thermal insulation, sound absorption, and humidity control; however, when the above-mentioned wood wool resin board absorbs water for a long time, it will have the disadvantage of water seepage deformation and disintegration of the shape, and its fire resistance The performance, weather resistance, corrosion resistance and output are not good, and cannot meet the actual market demand, so it cannot be widely accepted by the market; in addition, when a fire occurs, the resin will release toxic gas due to high temperature combustion, which is harmful to the environment and human health. will have harmful effects

[0003] In order to improve the above-mentioned conventional wood wool resin boards, wood wool cement boards with cement as the solidified product and a small amount of inorganic mineral additives are added to the cement to improve fire resistance, water resistance, weather resistance and acid and alkali resistance. However, the above-mentioned wood wool cement board uses a large amount of cement to achieve the effect of solidification, and its fire resistance basically only depends on the fire resistance of the cement itself, and does not do some flame retardant treatment for the wood wool fiber itself, so its fire resistance It is not ideal; in addition, due to the large amount of cement used, it will block and fill the
