Abstract

The present invention relates to a fireproof layer material, a preparation method thereof, and a fireproof glass. The fireproof layer material is prepared from the following raw materials in parts byweight: 50-300 parts of hydrophilic nano core-shell structured organic inorganic hybrid particles, 50-200 parts of deionized water, 5-200 parts of anti-condensation agent, 0.5-6 parts of charring agent, 0.5-6 parts of charring assistant, 0.5-6 parts of heat-resistant stabilizer, 0.05-1 part of ion fixing agent, 0.3-1.2 parts of storage stabilizer, 0.1-0.4 part of defoaming agent, 0.4-1.6 parts ofplasticizer, 0.2-1.2 parts of cross-linking agent, and 30-250 parts of potassium hydroxide aqueous solution with a mass percentage concentration of 50%, wherein the hydrophilic nano core-shell structured organic inorganic hybrid particles are widely distributed nano-particles. The fireproof layer material has the characteristic of shear thinning and can be poured into a thinner glass cavity. A composite fireproof glass prepared from the fireproof layer material has the advantages of no microbubble, good adhesion, high hardness, high transmittance, long fireproof time, and low temperature resistance.

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...
