Abstract

The invention provides a thermal insulation wall and a preparation method thereof and relates to the technical field of building materials. The thermal insulation wall comprises the following raw materials: pine fly ash, river sand, quartz sand, rice straws, bagasse, oat hulls, cottonseed hulls, cement, sepiolite fibers, rock wool, aerogel, polyamide resin, quartz glass fibers, a ceramic matrix composite, sodium fluosilicate, ceramic fibers, nanometer silicon carbide, floating beads, expanded glass beads, a flame retardant, a water reducing agent, a set retarder, an air entraining agent and water. The preparation method comprises the following steps: (1) raw material weighing; (2) river sand treatment; (3) material preparation; (4) screen fabric preparation; (5) mixing and stirring; and (6) in-mold pouring, demolding and maintaining. The thermal insulation wall prepared by the invention has the advantages of good thermal insulation property, good fireproofness, high fracture and compressive strength, small mass and low production cost.

Description

Technical field: [0001] The invention belongs to the technical field of building materials, and in particular relates to a thermal insulation wall and a preparation method thereof. Background technique: [0002] Walls are important structural components of buildings. In the prior art, there are a large number of wall materials that use fly ash and sand and gravel to mix and prepare, and then mix them with cement to prepare wall materials with thermal insulation performance. However, there are strict requirements for such materials, such as flexural resistance Compressive strength, light weight, low production cost, etc. [0003] In addition, in order to ensure the safety of people in the building, it is also necessary for the wall to have good fire performance. [0004] However, the existing walls lack the properties of good thermal insulation, good fire resistance, high flexural and compressive strength, light weight and low manufacturing cost.
