Inorganic light thermal insulating wallboard and manufacturing method thereof

Abstract

The invention discloses an inorganic light thermal insulating wallboard and a manufacturing method thereof. The inorganic light thermal insulating wallboard comprises the following components in parts by mass: 10-30 parts of cement, 40-60 parts of coal ash, 10-15 parts of waste slag, an inorganic foaming agent accounting for 3-5% of the cement, and an assistant accounting for 0.05-0.5% of the inorganic foaming agent, wherein the inorganic cement foaming agent is 90-95% hydrogen peroxide and 5-10% of ammonium carbonate. The manufacturing method of the inorganic light thermal insulating wallboard comprises the steps of mixing the cement, the coal ash and the waste slag with water to form concrete grout, adding the inorganic cement foaming agent and the assistant to the concrete grout, stirring, allowing concrete to be foamed rapidly, casting the foamed concrete into a mold, and allowing the foamed concrete to be solidified, demolded and stacked automatically and cured naturally. The inorganic light thermal insulating wallboard is low in heat conductivity coefficient, good in noise control and sound-proof effect, fire-proof, low in volume-weight, moderate in strength, nontoxic and odorless, and insulates heat. Raw materials are easy to obtain, the cost and equipment investment are low, the technological operation is simple, and the wallboard takes effect rapidly, and is worth for extensive popularization and application.
