Preparation process of novel water-based nano thermal insulation material

Abstract

The invention discloses a preparation process of a novel water-based nano thermal insulation material. The preparation method comprises the steps of firstly, preparing the following raw materials: a porous water-based nano silicon dioxide suspension, nano titanium dioxide, modified attapulgite, a wetting agent, modified fly ash, a thickening agent, modified montmorillonite, inorganic fibers, modified expanded perlite, a flame retardant, a defoaming agent, vitrified micro bubbles, an ethylene-vinyl acetate copolymer and deionized water; then preparing a mixture A; then preparing a mixture B; and finally, stirring the porous water-based nano silicon dioxide suspension, the mixture A, the mixture B, the wetting agent, the thickening agent, the defoaming agent and the flame retardant, and fully stirring and mixing to obtain the required novel water-based nano thermal insulation material. The product disclosed by the invention has excellent thermal insulation performance, and particularly, the modified attapulgite and the modified montmorillonite are added, and the thermal insulation effect can be further improved through synergistic interaction of the two components.

Description

technical field [0001] The invention relates to the technical field of preparation of thermal insulation materials, in particular to a preparation process of a novel water-based nano thermal insulation material. Background technique [0002] Thermal insulation materials generally refer to materials with a thermal coefficient less than or equal to 0.2. Today, global thermal insulation materials are developing in the direction of high efficiency, energy saving, thin layers, heat insulation, and waterproof and external protection. In the development of new thermal insulation materials and In line with structural thermal insulation and energy-saving technology, more emphasis is placed on the targeted use of thermal insulation materials, design and construction according to standard specifications, and efforts to improve thermal insulation efficiency and reduce costs. [0003] Most of the existing thermal insulation materials are ordinary and common inorganic thermal insulation m...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing thermal insulation materials are ordinary and common inorganic thermal insulation materials, such as rock wool, glass wool, vitrified microspheres, etc. Although the combustion performance reaches Class A, the thermal conductivity is poor, and the thermal insulation performance is not good, and even Ineffective in contact with water, more and more unable to meet higher usage requirements
