Embodiment Construction

[0009] Preparation of modified phosphogypsum powder: Take 49.5 kg of phosphogypsum, 1.6 kg of alum, and 3.9 kg of quicklime, mix them evenly and put them in a dryer for drying. Keep the drying temperature at 105°C. When the moisture is lower than 8%, it is Stop drying; then put the mixture into a calciner for calcination at 260° C. for 1 hour, and obtain modified phosphogypsum powder after cooling.

[0010] Preparation of paint: Take 55 kg of modified phosphogypsum powder, 25 kg of heavy calcium carbonate, 10 kg of sodium silicate, 5 kg of glass fiber, 6 kg of fly ash, and 1 kg of paint rubber powder and mix them; Pour tap water into the mixture to make it creamy and apply it on the wall, let it dry.

[0011] After the paint dries, the wall surface is smooth and smooth to the touch. Dust can be wiped off with a damp rag, and there is no powder on the wall.

Abstract

The invention discloses a ceramic-like coating which belongs to the technical field of architectural ceramic-like coatings. The ceramic-like coating comprises the following raw materials: 50-60 parts by weight of modified phosphogypsum powder, 20-30 parts by weight of heavy calcium carbonate, 10-20 parts by weight of sodium silicate, 3-5 parts by weight of glass fibre, 5-10 parts by weight of coal ash and 1-2 parts by weight of coating rubber powder. The ceramic-like coating has the advantages of high hardness, wiping resistance, no shedding, low cost, full utilization of phosphogypsum waste materials, thereby the environmental pollution caused by phosphogypsum is resolved.

Description

technical field [0001] The invention relates to an imitation porcelain paint, which belongs to the technical field of architectural anti-ceramic paint. Background technique [0002] Phosphogypsum is an industrial waste produced by the reaction of phosphate rock and sulfuric acid in the wet process of phosphoric acid production. A large amount of storage not only occupies land, but also causes environmental pollution. Contents of the invention [0003] The object of the present invention is to provide a kind of imitation porcelain paint, the present invention makes full use of the phosphogypsum waste material, solves the environmental pollution of phosphogypsum, meanwhile, the made porcelain imitation paint has high strength, scrub resistance, meets the environmental protection requirement. [0004] The present invention is achieved through the following measures: [0005] The ceramic paint of the present invention is characterized in that it is prepared from the following...
