Abstract

The invention provides a manufacturing method of an inorganic gel integrated timber based on a dry-pressing technology and a formula. The inorganic gel integrated timber comprises, by weight, 20-28% of magnesium oxide, 42.5-45.5% of a magnesium chloride solution with a Baume degree of 20-25 DEG C, 0.25% of an additive A (which is a liquid with a concentration of 5% prepared from a soluble sulfate and a soluble phosphate according to a ratio of 1: 1), 0.25% of an anti-explosion additive B (which is analytically pure tartaric acid) and the balance dry straws or wood chip particles. The manufacturing method of the inorganic gel integrated timber comprises 1, crushing dried straws or wood chips through a crusher and carrying out screening to obtain particles with granularity less than 8mm, 2, dissolving magnesium chloride solids in water to obtain a magnesium chloride solution with a Baume degree of 20-25 DEG C, and 3, mixing and stirring the above materials, injecting the mixture into a mold, pressurizing the mixture according to a ratio of 200-400t / m<2> to compact the mixture, carrying out standing curing and carrying out demolding. The inorganic gel integrated timber has uniform curing hardness, does not easily deform, can be easily cut, does not explode and can replace a timber material.

Description

technical field [0001] The invention relates to the technical field of integrated wood, in particular to an inorganic gelled integrated wood using a dry pressing formula and a manufacturing method thereof, which is particularly suitable for manufacturing high strength, not easily deformed, easy to cut, non-toxic, fireproof, and better in performance than wood of building materials. Background technique [0002] In order to protect the environment, care for forests and save energy, in recent years the existing technology has developed a composite material that can replace wood by adding magnesium chloride and magnesium oxide as base materials and adding dry plant particles. However, it has been proved by production and use that this kind of integrated composite material has always had the following shortcomings: first, it has low compressive and bending resistance, and the process is difficult to form. Sometimes fiber such as glass fiber has to be added to increase the tensil...
