High-performance heat preservation building material

Abstract

The invention discloses a high-performance thermal insulation building material, which is composed of the following raw materials in parts by weight: 22-32 parts of diatomite, 30-36 parts of quartz sand, 8-12 parts of plant fiber powder, and 10-32 parts of clay 16 parts, 4-10 parts of fly ash, 6-12 parts of filler, 1-3 parts of carboxylated nitrile rubber, 3-7 parts of polybutadiene rubber, 10-16 parts of waterproofing agent, 13-17 parts of flame retardant . The invention adopts a scientific raw material ratio, adopts diatomite, has no pollution to the environment, does not release toxic substances, and can improve indoor air; it solves the problem of energy saving and environmental protection, sound insulation, compressive strength and There are still insufficient problems in buildings with high thermal insulation performance requirements.

Description

Technical field [0001] The invention relates to a high-performance thermal insulation building material, belonging to the field of building materials. Background technique [0002] With the process of urbanization in China, infrastructure construction is not expanding much, so the demand for building materials has become higher and higher in quality. At present, most of the coatings used in building insulation have poor weather resistance. When the external temperature changes greatly, the coating film will crack. However, the existing waterproof materials can only be waterproof in a single layer, and the waterproof performance is not strong enough. The preparation method is not simple enough, and the heat preservation and fire resistance performance is not high. Summary of the invention [0003] In order to solve the above problems, the present invention provides a high-performance thermal insulation building material, which is composed of the following parts by weight: 22-32 pa...
