Embodiment Construction

[0032] The present invention contains a kind of wood material combined with airgel fireproof material manufacturing method, please refer to figure 1 As shown, the embodiment of the present invention includes the following steps:

[0033] A. Add an acid catalyst to a mixed solution of a precursor and an organic solvent to cause a hydrolysis reaction to form an airgel solution. This embodiment mainly provides a precursor of an alkoxysilane or a methyl orthosilicate, an organic solvent mixed with water and ethanol, and the molar ratio (mol%) of water and ethanol in the organic solvent The range is 10:1 to 120:8. The precursor and the organic solvent are fully stirred and mixed to form a mixed solution. In addition, the molar ratio of the precursor to water in the organic solvent is higher than 1:4, so that the precursor can accelerate the hydrolysis reaction. That is to say, the molar ratio content of the precursor accounts for 9% to 16% in the mixed solution (this embodiment ...

Abstract

The invention discloses a manufacturing method of a fireproof material for combining a wood material with aerogel. The manufacturing method comprises the following steps: (A) an acid accelerant is added in mixed solution of a precursor and an organic solvent for hydrosis reaction to form aerogel solution; (B) alkali accelerant water solution is added in the aerogel solution for condensation reaction to form aerogel water solution; (C) the wood material is dipped in the aerogel water solution for gelation to generate the aerogel to coat the wood material; and (D) the wood material is dried to mold the fireproof material. The invention further discloses the fireproof material for combining the wood material with the aerogel, which is manufactured by using the steps. The fireproof material can achieve excellent fireproof effect, and can pass through a combustion lowest-oxygen-content test.

Description

technical field [0001] The invention relates to a fireproof material combined with wood material and airgel and a manufacturing method thereof. Background technique [0002] Aerogels have many special properties, such as low density, high porosity, high specific surface area, and low thermal conductivity. At present, the manufacturing method of airgel is sol-gel synthesis method, after mixing precursors such as alkoxysilanes (Alkoxysilane) or methyl orthosilicate with aqueous organic solvents, adding an acid catalyst, and performing a hydrolysis reaction (Hydrolysis) ). After hydrolysis for a certain period of time, an alkali catalyst is added to carry out a condensation reaction (Condensation), which is called a sol solution during the condensation reaction. The silica molecules in the sol solution continue to condense and aggregate, and gradually form silica gel. [0003] In the traditional airgel solution, because it contains a large amount of ethanol (alcohol) molecul...
