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.

Problems solved by technology

[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 irregular voids formed when the wood wool is stirred, and through the cement as a medium, heat and sound waves will be transmitted quickly, which will reduce heat preservation, heat insulation, sound insulation, Sound-absorbing effect; because of the addition of a large amount of cement, the weight increases, the transportation is inconvenient, the color becomes darker, and there is also concern about deformation. Moreover, when the cement is exposed to high temperatures above 1000 degrees Celsius, cracks and strength decay will occur.

[0004] In addition, in terms of diversification of raw materials, there are currently attempts to use plant fibers other than wood wool as building material raw materials; however, cement-based hardeners will be affected by the sugar and lignin contained in plant materials, which will seriously hinder the curing phenomenon , so in addition to the limited selection of plant raw materials, the strength of the produced products will also be limited. In addition, additional processing of raw materials is required, which increases production costs; The treatment of the mineralization process is not thorough enough, the use of too much cement-based hardener and the difficulty in forming and curing, etc., and the poor technology of the mixing process, forming process and curing process cannot achieve light weight and strength at the same time. High and fire-resistant requirements, so it has not yet reached the stage of practicality and mass production

[0005] It can be seen that the conventional wood wool resin board, wood wool cement board, and plant silk mineralization technologies still have many deficiencies, which are not good designs and need to be improved urgently.
