Novel high-dimensional magnesium aluminum silicate thermal insulation material and preparation method thereof

Abstract

The invention discloses a novel high-dimensional magnesium aluminum silicate thermal insulation material. The novel high-dimensional magnesium aluminum silicate thermal insulation material contains the following components: zirconium-containing, high-aluminum or common aluminum silicate fibers, magnesium oxide fibers, potassium hexatitanate whisker fibers, white carbon black, glass beads, nanometer micro-powder, potassium silicate, a sodium solution, nano-magnesia, a water-proofing agent and hole-closed perlite. The invention further discloses a preparation method of the novel high-dimensional magnesium aluminum silicate thermal insulation material. The novel high-dimensional magnesium aluminum silicate thermal insulation material has the beneficial effects that the thermal insulation material is low in density, has the function of resisting pull and decreasing high-temperature thermal conductivity and low-solubility thermal conductivity and further has the effects of reducing cracking, deformation and collapse. A novel physical constitution is formed by virtue of a cheap magnesium aluminum silicate material, a production process is innovated, and the low-volume-weight, low-thermal-conductivity and high-strength novel magnesium aluminum silicate thermal insulation material is innovated, so that the powerful popularization of new techniques, new materials and new products is promoted, and a new application market is expanded.

AI Technical Summary

Problems solved by technology

[0003] However, among these super thermal insulation and high-grade thermal insulation materials, the raw materials of some materials (nano 2ro2, nano sio2, si3N4 nano powder, pyrite, sodium lignosulfonate) are very expensive, which in turn causes the product price to be extremely high, and can only be used For cutting-edge rare high-tech products

Compared with basic industries and large-scale general-purpose industries, it is difficult to popularize and promote applications due to their high cost. The effect is particularly obvious when it is applied in a fairly static working state, such as foaming materials used for building wall insulation, etc.

For mechanical equipment pipelines that move, vibrate, and are often subject to external collisions, tramples, and gravity pressures, high volume density is often required in the state of the board wall, so the thermal conductivity is high, which affects the heat insulation effect. It is subject to a certain lack, and the promotion and use are limited
