Abstract

The invention relates to the technical field of cements, and concretely relates to a foaming cement slab and a preparation method thereof. The foaming cement slab is mainly prepared from the raw materials: 60 to 70 parts of cement, 10 to 15 parts of tetrasodium iminodisuccinate, 10 to 15 parts of ethylene diamine tetraacetic acid dipotassium ethylene dinitrilotetra-acetic acid, 10 to 15 parts of potassium chromate, 5 to 10 parts of tetrahydro-iso-humulone, 5 to 10 parts of 4,4-diphenylhydrazine diphenyl ether4,4-disulfonylhydrazide diphenyl ether, 5 to 10 parts of 4,4'-p-sulfonylhydrazide diphenyl ether 4,4'-oxybis(benzenesulfonyl hydrazide), 2 to 4 parts of sodium alkyl sulfate, 2 to 4 parts of heavy sodium alkyl benzene sulfonate, 0.3 to 0.5 part of sodium polymethacrylate, 0.3 to 0.5 part of sodium amine sulfonate, 0.5 to 0.7 part of 2,3-dihydrobutanedioic acid, 0.5 to 0.7 part of sodium hexametaphosphate, and the like. The preparation method comprises the steps of mixing the raw materials, injection molding, maintaining, demoulding and the like, and is simple in process and easy to operate. The foaming cement slab provided by the invention is low in heat conductivity coefficient, light in weight, less in water consumption, prolonged in initial setting time, sufficient in foaming, waterproof, and better in heat insulation and sound insulation effects.

Description

technical field [0001] The invention relates to the technical field of cement, in particular to a foamed cement board and a preparation method thereof. Background technique [0002] Foamed cement is currently widely used in the construction field, and it is an ideal thermal insulation, sound insulation, heat insulation and fireproof material. The existing foam cement technology has the problem of poor foaming effect caused by too fast solidification speed, which will directly lead to the decline of thermal insulation effect, and at the same time, it is tight with the connection part of the cavity, which is prone to peeling off Contents of the invention [0003] The purpose of the present invention is to: aim at the above existing problems, to provide a foamed cement board and its preparation method, which has low thermal conductivity, less water consumption, prolonged initial setting time, good foaming effect, good waterproof, heat preservation and Sound insulation effect...
