Thermal insulation material and preparation technology thereof

Abstract

The invention provides a preparation technology of a thermal insulation material. The preparation technology comprises mixing basalt rock powder, white rock powder and coke by stirring, putting the mixture into a cupola furnace, carrying out melting, spraying the liquid to phenolic resin, carrying out centrifugation so that fibers are formed, collecting the fibers, carrying out S-shaped overlaying by a pendulum swinging way to obtain overlaid fibers, spraying an amine curing agent to the surfaces of the overlaid fibers to cure the overlaid fibers, simultaneously carrying out compression to obtain a thermal insulation rock plate, and carrying out segmentation, packaging, quality inspection and warehousing. Through use of nanometer basalt rock powder and white rock powder, fluidity and good mixing effects of the raw materials in melting are improved and uniform raw material mixing effect is realized. The preparation technology utilizes a dissolution method in melting, in dissolution, coke and liquid oxygen are used, the solution can be directly heated in the furnace, energy usage is reduced and heat efficiency is improved.

Description

Technical field [0001] The invention belongs to a method for preparing a thermal insulation material, and particularly provides a method for preparing a slate thermal insulation material. Background technique [0002] With the implementation and development of building energy saving, heat preservation materials and products have attracted more and more attention. At present, most of the materials used are benzene board and other materials. Its flammability and the phenomenon that environmental pollutants are easily generated in the production and installation process have always been the drawbacks of this kind of material. Summary of the invention [0003] The purpose of the present invention is to provide a preparation process of the thermal insulation material. [0004] The present invention specifically provides a preparation process of an insulation material, including the following steps: [0005] a. After mixing 10-20 parts of basalt rock powder, 0-5 parts of white rock powder...
