Abstract

The invention discloses a hydraulic engineering thermal insulation material, and relates to the technical field of thermal insulation material production. The hydraulic engineering thermal insulation material is prepared from the following raw materials by weight: 20-30 parts of slag cement, 5-10 parts of mica powder, 5-10 parts of a porous material, 2-3 parts of glass micro-beads, 0.6-1 part of a foaming agent, 1-2 parts of polyaluminum chloride, 1-2 parts of potassium polyacrylate, and 18-25 parts of water. According to the invention, the porous material prepared from the waste ceramic and the plant fibers is added into the thermal insulation material, so that the thermal insulation material is good in thermal insulation performance, high in strength, economical and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of thermal insulation material production, in particular to a thermal insulation material for water conservancy projects and a preparation method thereof. Background technique [0002] Most of the dams and dikes constructed by water conservancy projects are concrete structures. Water conservancy projects in alpine regions are affected by the low temperature in winter, and the concrete of the dam body is subject to the impact of cooling, which is prone to temperature stress and cracks, which affects the durability of the structure of the water conservancy project. It is also crucial to construct insulation materials on the surface of the dam body. [0003] Chinese patent document (CN 111908865 A) discloses a kind of wear-resisting thermal insulation building mortar and its preparation method, the mortar is prepared by mixing powder and water, wherein the weight ratio of powder and water is 100:20-30; wherein ...
