Production method of cement-based thermal insulation material

Abstract

The invention discloses a production method of a cement-based thermal insulation material, comprising the following steps: S1: preparing a thermal insulation material matrix, the thermal insulation material matrix including a carrier and thermal insulation powder; S2: preparing adhesive microcapsules and foaming microcapsules; S3: mix the thermal insulation material matrix, the conductive microcapsule adhesive microcapsule and the foaming microcapsule according to the ratio in the set mold; S4: use the high-frequency coil to energize the microcapsule to cause micro-explosion, and use the described Adhesive microcapsules glue the thermal insulation material matrix into a whole, and use the foamed microcapsules to generate air bubbles inside the whole; S5: by filling the mold or the whole into the actual engineering site, adding an appropriate amount of mixing Combine water to obtain cement-based insulation materials. The cement-based thermal insulation material produced by the invention has the characteristics of simple construction, good material homogeneity, excellent thermal insulation performance and high strength.

Description

technical field [0001] The invention relates to the field of thermal insulation building materials, in particular to a production method of cement-based thermal insulation materials. Background technique [0002] Since cement was invented at the beginning of the 19th century, because it is a hydraulic cementitious material, it can be hardened in air or better hardened in water, and can firmly bind sand, stone and other materials. It is glued together, so it is widely used in civil construction, water conservancy, national defense and other projects. Because cement-based cementitious materials have good strength and durability, they have become the most widely used and largest building materials at present. [0003] Although the thermal conductivity of traditional cement-based materials is lower than that of steel materials, the thermal insulation performance is better than that of steel materials. However, with the improvement of living standards, people pay more and more ...

AI Technical Summary

Problems solved by technology

In the prior art, thermal insulation materials made of cement-based materials are usually formed by adding some physical or chemical foaming agents on the basis of cement materials to form foam boards, but the control and distribution of air bubbles are difficult to control, and the overall thermal insulation material The thermal conductivity is not uniform, and the requirements for actual mixing and construction technology are relatively high

Traditional cement-based materials usually use ordinary Portland cement, resulting in low overall strength of the insulation material
