Abstract

The invention relates to a ceramic microbead gel material and a preparation method thereof. The ceramic microbead gel material comprises vacuum ceramic microbeads, silicon carbide fibers, a gelling agent, a lithium silicate solution, a sodium silicate solution, a benzene-acrylic emulsion, polyacrylamide, hexadecyl trimethyl ammonium bromide, Tween-80, water and a conditioning agent. According to the material disclosed by the invention, the vacuum ceramic microbeads are used as a heat-insulating functional material, the hexadecyl trimethyl ammonium bromide is used as a dispersing agent, so that other solutes are accelerated to dissolve and are uniformly dispersed, the high-temperature-resistant silicon carbide fibers are used as a reinforcing material, and the gel material has high smearing property and water-retaining property and is prevented from cracking due to the gelling agent; tween-80 is used as a stabilizer, a lithium silicate solution and a sodium silicate solution are added, so that the heat conductivity coefficient of gel is reduced, and the gel and the vacuum ceramic microbeads form a more compact vacuum heat insulation structure, so that the composite coating which has a high-temperature heat insulation function and is excellent in smearing performance and water resistance is prepared.

Description

technical field [0001] The invention relates to a ceramic microbead gel material and a preparation method, and belongs to the technical field of functional materials. Background technique [0002] At present, the commonly used wall insulation materials include mineral rock wool, glass wool, foam plastic, polyester resin, calcium silicate board, etc. These insulation materials have different degrees of low compressive strength, poor water resistance, and high temperature resistance. The disadvantage is that the process is complicated, but the biggest disadvantage is that the cost is generally higher, especially the higher price of polyester resin and calcium silicate board. Some thermal insulation materials also produce pollution during the manufacturing process, and some use polyphenylene particles as wall insulation layers. Then apply the adhesive fiberglass mesh cloth to strengthen it, and then apply the cement mortar twice. Although the cost per unit area of ​​this meth...
