Abstract

The invention discloses a fireproof cement foam insulation board, comprising the following components in parts by weight: 38-45 parts of sulphate aluminium cement, 28-33 parts of fly ash, 0.28-0.35 part of wooden anti-crack fiber, 2.9-3.5 parts of waterproof agent, 0.55-0.75 parts of calcium stearate, 0.18-0.25 parts of polycarboxylate superplasticizer, 2.0-3.0 parts of GM-A foaming agent, and 25-30 parts of water. The fireproof cement foam insulation board disclosed by the invention is simple in manufacturing technique, good in insulation and waterproof effects of products, and inflammable.

Description

technical field [0001] The invention belongs to the field of cement building materials, and in particular relates to a cement foam fireproof and thermal insulation board. Background technique [0002] As the country pays more and more attention to building energy-saving technology for roof and wall insulation, various types of external wall insulation materials continue to appear in the market. However, currently commonly used insulation materials such as polystyrene board, extruded board and foamed phenolic resin have disadvantages such as flammability, aging, high cost and short service life. Especially in recent years, fire accidents ignited by building exterior wall insulation materials have occurred frequently, and the fire safety of building exterior wall insulation systems has been valued by relevant national ministries and commissions. [0003] The existing cement-foamed fire-proof insulation board adopts adding surfactant to cement and fly ash, and uses a f...
