Production method of cement-based heat insulation material

Abstract

The invention discloses a production method of a cement-based heat insulation material. The method comprises the following steps of S1, preparing a heat insulation material base body which comprises acarrier and heat insulation powder; S2, preparing adhesive microcapsules and foaming microcapsules; S3, proportionally mixing the heat insulation material base body, the conductive adhesive microcapsules and foaming microcapsules in a set mold according to the proportion; S4, using a high-frequency coil for electrification so that the microcapsules generate micro explosion; using the adhesive microcapsules for bonding the heat insulation material base body into a whole; using the foaming microcapsules to generate bubbles inside the whole; S5, under the condition of being in a mold or fillingthe whole to the practical engineering part, adding a proper amount of stirring water to obtain cement-based heat insulation material. The cement-based heat insulation material produced by using the method has the characteristics that the construction is simple; the material homogeneity is good; the heat insulation and thermal isolation performance is excellent; the intensity is high, and the like.

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
