High-performance foam concrete insulation board and preparation method thereof

Abstract

The invention belongs to the field of an external wall insulation material of a building, and particularly relates to a high-performance foam concrete insulation board and a preparation method thereof. The high-performance foam concrete insulation board is prepared from the following raw materials in parts by weight: 45-250 parts of cement, 10-125 parts of admixture, 6-30 parts of foaming agent, 40-130 parts of water, 0.8-5.5 parts of additive, and 2-11 parts of modifier in a mixed casting manner. The insulation board provided by the invention is light in weight, high in strength and excellent in waterproofness.

Description

technical field

[0001] The invention belongs to the field of thermal insulation materials for building exterior walls, and relates to a high-performance foam concrete thermal insulation board and a preparation method thereof. Background technique

[0002] At present, in the organic materials commonly used in the building exterior wall insulation material market, such as polystyrene foam boards, phenolic foam boards, etc., their fire performance is extremely poor and they are easy to burn. Poor performance, short service life and high replacement cost. Among inorganic thermal insulation materials: foam glass, foam aluminum, and foam ceramics have high cost prices; although fiber thermal insulation materials such as rock wool are slightly lower in price, they are not hard materials, have poor constructability, and are harmful to human health. It is easy to make people itchy all over the body, silicosis, etc.; in addition, granular loose insulation materials such as expanded p...
