Embodiment 1

[0019] Mix 525 ordinary Portland cement, fly ash, fiber reinforced material, and foaming and stabilizing dispersant first, by weight, including 140 parts of cement, 50 parts of fly ash, 1 part of fiber reinforcing material, and foaming and stabilizing dispersion 4 parts of agent, 7 parts of iron black powder. Add 100 parts of hot water at 40-60 degrees to the mixed powder and stir for 10 minutes to form a slurry. Add 12 parts of foaming agent (hydrogen peroxide) to the well-stirred slurry, stir for 30 seconds, immediately pour into the mold to foam, heat and solidify with a warm room, demould, and maintain at room temperature for 24 hours, cut into decorative plates, and naturally cure 30 days.

Abstract

The invention discloses a preparation method of a black foamed cement insulation board, and belongs to the field of building materials, and the preparation method comprises the following steps: uniformly mixing cement, fly ash, a fiber reinforced material and a foaming stabilizing dispersant, adding hot water at 40-60 DEG C, stirring the components to form slurry, adding a foaming agent, uniformlystirring the mixture, pouring the mixture into a mold, foaming the mixture, and curing and molding the foamed product in a greenhouse, and demolding the product; and maintaining the shaped product atnormal temperature for 24 hours, cutting the product into decorative plates, and naturally curing the decorative plates for 30 days. The decorative plate has excellent strength, heat preservation andcolor effect, and reaches the flame retardant property grade-A.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a preparation method of a black foamed cement insulation board. Background technique [0002] Cement foam board is launched in response to the national "Interim Regulations on Fire Protection of Civil Building External Thermal Insulation System and External Wall Decoration". [0003] The existing cement foam insulation boards in the market have uneven technical levels and unstable quality. The main problems are easy mold collapse during production, uneven bubble size, uneven distribution, and poor color. These directly affect the promotion and use. Contents of the invention [0004] The object of the present invention is to provide a method for preparing a black foamed cement insulation board with stable quality, good flame retardancy, thermal insulation and color effect in view of the defects in the prior art. [0005] The technical scheme adopted for realizing ...
