Desulfurization gypsum powder decorating board

Abstract

The invention discloses a desulfurization gypsum powder decorating board. A raw material formula of the desulfurization gypsum powder door pocket board is as follows: 60-70 percent of desulfurization gypsum powder, 8-12 percent of epoxy resins, 4.8-5.2 percent of polyvinyl chloride, 4.8-5.2 percent of foam regulating agents, 4.8-5.2 percent of activated charcoal (AC) foaming agents, 2.8-3.2 percent of stearic acid, 3.8-4.2 percent of calcium stearate and 4.8-5.2 percent of glazes. A preparation method of the desulfurization gypsum powder decorating board comprises the following steps of: (1) weighing the materials in the proportion of the raw material formula; (2) mixing and stirring the weighed materials; (3) performing extrusion molding on a mixed material by virtue of an extruding machine; (4) heating and conserving molded blank bodies; (5) manufacturing semi-finished products which are subjected to the conservation to be blank bodies by using a board pressing machine; (6) delivering the pressed blank bodies to a drying kiln for drying; (7) performing atomization and glaze spraying on the dried desulfurization gypsum powder decorating board by using the conventional method; and (8) drying the desulfurization gypsum powder decorating board onto which the glazes are sprayed. The desulfurization gypsum powder decorating board has the advantages of corrosion resistance, weather resistance and the like.

Description

technical field [0001] The invention relates to the field of building boards, in particular to a desulfurized gypsum powder decorative board. Background technique [0002] Coal-fired power generation is the largest emitter of sulfur dioxide, so our government attaches great importance to it. Thermal power plants consume more than 50% of the country's coal while converting chemical energy into electrical energy. Coal ash, desulfurized gypsum and other solid emissions, as the national environmental protection requirements for desulfurization of power plants are getting higher and higher, the output of desulfurized gypsum is increasing, and the environmental pollution caused is also increasing. How to dispose of this large amount of "waste It is the subject of the development of circular economy to turn "things" into important mineral resources. The main component of desulfurization gypsum is calcium sulfate dihydrate crystals. It is made of ester baking paint or fluorocarbon ...

[0002] Coal-fired power generation is the largest emitter of sulfur dioxide, so our government attaches great importance to it. Thermal power plants consume more than 50% of the country's coal while converting chemical energy into electrical energy. Coal ash, desulfurized gypsum and other solid emissions, as the national environmental protection requirements for desulfurization of power plants are getting higher and higher, the output of desulfurized gypsum is increasing, and the environmental pollution caused is also increasing. How to dispose of this large amount of "waste It is the subject of the development of circular economy to turn "things" into important mineral resources. The main component of desulfurization gypsum is calcium sulfate dihydrate crystals. It is made of ester baking paint or fluorocarbon paint, carved aluminum-zinc alloy steel plate, polyurethane insulation layer, and glass fiber cloth; it is mainly used for exterior wall decoration and energy saving of various buildings such as gymnasiums, libraries, school and hospital office buildings, villas, etc. Renovation; the main functions are architectural decoration, heat preservation and energy saving, heat insulation and sound insulation, waterproof and mildew proof, etc. However, the production cost of this kind of exterior wall decorative board is high and it is not suitable for mass consumption
