Embodiment Construction

[0031] The present invention contains a kind of organic foam combined with airgel fire prevention material manufacturing method, please refer to figure 1 As shown, the embodiment of the present invention includes the following steps:

[0032]A. Add an acid catalyst to a mixed solution of a precursor and an organic solvent to cause a hydrolysis reaction to form an anhydrous airgel solution. This embodiment mainly provides a precursor of an alkoxysilane or a methyl orthosilicate, and an organic solvent mixed with water and ethanol. The alkoxysilane is tetraethylsiloxane (Tetraethoxysilane, TEOS). The mixing ratio range is that the molar ratio (mol%) of the precursor (tetraethylsiloxane) to the organic solvent ranges from 1:9 to 1:18, wherein the molar ratio of the precursor to water ranges below 1:4, then add an acid catalyst, the molar ratio of the precursor mixed with the acid catalyst ranges from 1:0.001 to 1:0.1, stir at room temperature to carry out a hydrolysis reaction,...

Abstract

The invention discloses a manufacture method of a fireproof material prepared from organic foam combined with aerogel. The method comprises the following steps: A, adding an acid accelerant into a mixed solution of a precursor and an organic solvent, so as to ensure that the mixed solution is subjected to hydrolysis reaction to form an anhydrous aerogel solution; B, adding an alkali accelerant aqueous solution into the anhydrous aerogel solution, so as to ensure that the anhydrous aerogel solution is subjected to condensation reaction to form an aerogel solution; C, soaking organic foam into the aerogel solution, producing aerogel through gelatinization, and combining the aerogel with the organic foam to form a stereochemical network structure; D, drying the organic foam to form a fireproof material. The invention further discloses a fireproof material prepared from organic foam combined with aerogel, which is manufactured through the steps. The fireproof material has an excellent fireproof effect, and passes a combustion minimum oxygen content test.

Description

technical field [0001] The invention relates to a fireproof material combined with organic foam 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, add an alkali catalyst to carry out a condensation reaction (Condensation), and a sol will be formed after the reaction. The molecules in the sol continue to undergo condensation reaction bonding, gradually forming a semi-solid polymer gel, and after a period of aging, the colloid will form a three-dimensional network structure with stable structure.
