Embodiment 1

[0032] First respectively crush the waste polystyrene foam, industrial production waste coal cinder or fly ash, and building demolition waste building residue; 10 kg of building demolition waste and old construction residues were mixed and stirred evenly to obtain a plate base material. Weigh 1 kg of polyvinyl alcohol, 0.2 kg of polyacrylic acid, 0.04 kg of methyl cellulose, 0.02 kg of lignin, 0.1 kg of boric acid, 0.04 kg of calcium sulfonate, and 0.02 kg of calcium chloride, mix them well and stir them evenly. After irradiating with Co-γ rays for 1 h, the sheet cementitious material was prepared. Mix the prepared plate base material and plate cementitious material with 30 kg of low-alkali sulfoaluminate cement and 15 kg of water, stir evenly, add to the prefabricated mold, stir and pressurize, keep for 24 hours, and demould to obtain the mold sheet. The resulting formed plate has low unit mass and low strength, which is good for processing.

Embodiment 2

[0034] First respectively pulverize waste polystyrene foam, industrial production waste cinder or fly ash, building demolition waste building residue, industrial production waste desulfurization gypsum; then weigh 30 kg of crushed waste polystyrene foam, industrial production waste cinder or 10 kg of fly ash, 10 kg of waste building residues from building demolition, and 5 kg of waste desulfurized gypsum from industrial production were mixed and stirred evenly to prepare the board base material. Weigh 5 kg of polyvinyl alcohol, 3 kg of polyacrylic acid, 0.2 kg of methyl cellulose, 0.5 kg of lignin, 1 kg of boric acid, 0.5 kg of calcium sulfonate, and 0.2 kg of calcium chloride, mix them well and stir them evenly. After irradiating with Co-γ rays for 5 hours, the sheet cementitious material was prepared. The preparation sequence of the sheet base material and the sheet cementitious material can be determined according to the actual operation situation, either the sheet base mat...

Embodiment 3

[0036] First respectively pulverize waste polystyrene foam, industrial production waste cinder or fly ash, building demolition waste building residue, industrial production waste desulfurization gypsum; then weigh 20 kg of crushed waste polystyrene foam, industrial production waste cinder or 15 kg of fly ash, 5 kg of waste building residues from building demolition, and 5 kg of waste desulfurized gypsum from industrial production were mixed and stirred evenly to prepare the board base material. Weigh 2 kg of polyvinyl alcohol, 1.2 kg of polyacrylic acid, 0.28 kg of methyl cellulose, 0.04 kg of lignin, 0.2 kg of boric acid, 0.28 kg of calcium sulfonate, and 0.16 kg of calcium chloride, mix them well and stir them evenly. Under the irradiation of Co-γ ray for 10h, the sheet cementitious material was prepared. Add 20 kg of water to the prepared board base material and 32 kg of low-alkali sulfoaluminate cement to prepare a mixed slurry; add 10 kg of water to the prepared board cem...

Abstract

The invention discloses a processing method of a novel light energy-saving environmental-protection board, belonging to the field of processing professional technology of building wall body material; the basic technical proposal is that: the novel light energy-saving environmental-protection board is manufactured by the waste polystyrene foam, industrial production waste coal cinder or coal ash, building-removal waste residue, industrial production waste desulfuration gypsum, low-alkali sulphate aluminium cement, special chemical additive and water by weight parts, wherein the special chemical additive is prepared by radiating polyvinyl alcohol, polyacrylic acid, methylcellulose, lignin and boric acid which have a certain weight parts by Co-gamma rays; compared with the traditional wall body material, the novel composite molding board has the advantages of low cost, temperature insulation, energy saving, high-intensity shock resistance, sound insulation, moisture proofing, durability,light weight, simple manufacturing process, convenient construction, and being capable of fastening hangers, is completely accordance to the national green development requirements of energy saving, environment protection and waste utilization, therefore, the processing method of the novel light energy-saving environmental-protection board is an ideal sustainable development green wall body material.

Description

technical field [0001] The invention belongs to the professional technical field of building wall material processing, and specifically relates to a method for processing light-weight energy-saving and environment-friendly boards by using waste polystyrene foam, industrial production waste cinder or fly ash, and building demolition waste and old building residue. Background technique [0002] Building energy efficiency benefits the country and the people, and the development of energy-saving building materials can fully save land, waste, and protect the environment, which is conducive to promoting economic growth and building a harmonious society. my country is a developing country with relatively poor resources per capita. At present, the leading product of my country's wall materials is solid clay bricks. The annual energy consumption of wall materials production and building heating is nearly 150 million tons of standard coal, accounting for about 15% of the total annual ...
