Abstract

The invention relates to a composite foamed cement insulation board for a tile surface. The insulation board consists of the following components in part by weight: 100 parts of portland cement, 20 to 40 parts of fly ash, 60 to 65 parts of water, 0.3 to 0.5 part of fibers, 1 to 2 parts of early strength agent, 0.5 to 1 part of accelerator, 0.5 to 0.8 part of water reducing agent, 1.3 to 2.0 parts of foam stabilizer and 5.5 to 6.5 parts of foaming agent. A preparation method of the composite foamed cement insulation board comprises the following steps of: firstly, preparing the accelerator; then adding the portland cement, the fly ash, the water, the fibers, the early strength agent, the accelerator and the water reducing agent into a mixing tank to stir and pulp; and finally, adding the foam stabilizer and the foaming agent, pouring the mixture into a die after uniformly stirring, naturally carrying out foam forming in the die, maintaining in the natural state, and finally cutting into blocks and packaging. The composite foamed cement insulation board disclosed by the invention has the tensile bond strength greater than or equal to 0.2MPa and can be used for the tile surface.

Description

technical field [0001] The invention relates to a thermal insulation board material, and more specifically relates to a composite foamed cement board thermal insulation which can be used for ceramic tile decoration and a preparation method thereof. Background technique [0002] According to Article 2 of the People's Republic of China's "Interim Provisions on Fire Protection of Civil Building External Thermal Insulation Systems and External Wall Decoration", the external thermal insulation materials of civil buildings must use materials with a combustion performance of Class A. According to this regulation, the original civil building external thermal insulation systems were widely used The use of organic boards such as XPS and EPS is prohibited. Various insulation boards on the market that can meet Class A fire protection standards such as rock wool boards, glass wool, foamed ceramics, foam glass, expanded perlite and other insulation materials are flourishing. Among them, t...
