Building thermal insulation material and preparation method thereof

Abstract

Relating to the field of building materials, the invention provides a building thermal insulation material and a preparation method thereof. The building thermal insulation material comprises the following raw materials by weight: 30-50 parts of diatomite, 15-20 parts of expanded perlite, 20-30 parts of vermiculite, 15-25 parts of flexible ceramic, 22-30 parts of ash calcium powder, 15-20 parts of quartz sand, 0.5-1.5 parts of fly ash, 12-22 parts of polyethylene foam plastic, 15-25 parts of negative ion powder for building, 10-15 parts of stearic acid, 5-11 parts of sodium formate, 10-12 parts of inorganic fiber, 5-9 parts of a cementing material, 10-14 parts of filler, 1-2 parts of an exciting agent, 0.3-0.7 part of a water reducing agent and 4-8 parts of water. The preparation method includes the steps of: (1) raw material weighing, (2) vermiculite roasting, (3) crushing of flexible ceramic and polyethylene foam plastic, (4) stirring, and (5) molding, demolding, stacking and maintenance. The building thermal insulation material and the preparation method provided by the invention solve the problem that disadvantages exist in application of existing building thermal insulation materials to building with high requirements for energy saving and environmental protection, sound insulation, compressive strength and thermal insulation performance.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a building thermal insulation material and a preparation method thereof. Background technique [0002] With the implementation and development of building energy conservation, thermal insulation materials and products have been paid more and more attention by people. However, the currently used materials are not ideal in various properties, especially in terms of heat preservation, acid and alkali resistance, and weather resistance, which cannot meet people's needs. At present, the most commonly used thermal insulation material for exterior walls is polystyrene plastic foam board, and its main material is polystyrene resin. Because of its high transparency, good rigidity, and good chemical corrosion resistance, it has been favored by people. , however, it has the defects of large specificity, large thermal conductivity, prone to stress cracking, and high cost.
