Abstract

The invention relates to a fire-proof layer material, a preparation method thereof and fire-proof glass. The fire-proof layer material is prepared from raw materials in parts by weight as follows: 50-300 parts of hydrophilic nano core-shell structure type organic / inorganic hybrid particles, 50-200 parts of deionized water, 5-200 parts of a condensation resistant agent, 0.5-6 parts of a carbon forming agent, 0.5-6 parts of a carbon forming aid, 0.5-6 parts of a heat-resisting stabilizer, 0.05-1 part of an ion fixing agent, 0.3-1.2 parts of a storage stabilizer, 0.1-0.4 parts of a defoaming agent, 0.2-1.2 parts of a cross-linking agent and 30-250 parts of a potassium hydroxide aqueous solution with mass fraction being 50%. The hydrophilic nano core-shell structure type organic / inorganic hybrid particles are widely distributed nanoparticles. The fire-proof layer material has the characteristic of shear thinning and can be used for filling a thinner glass cavity. The composite fire-proof glass prepared from the fire-proof layer material has the advantages of being free of microbubbles, good in adhesion, high in hardness, high in transmittance, long in fire-proof time and resistant to low temperature.

Description

technical field [0001] The invention relates to the field of safety glass, in particular to a fireproof layer material, a preparation method thereof and fireproof glass. Background technique [0002] As the pace of urbanization progresses faster and faster, the architectural windows of houses are also becoming larger and larger. Elegant, beautiful and functionally safe glass components are gradually being favored by domestic and foreign designers, which directly leads to the rapid development of various safety glass and special glass in the architectural glass industry. Architectural glass has gradually developed from simply being used as a lighting and decorative material to a composite direction with multiple functions such as light control, room temperature adjustment, noise reduction, and improvement of the living environment. [0003] In addition to some properties of ordinary glass, fire-resistant glass also has the properties of controlling fire spread, smoke insulat...
