Environment-friendly material and preparation method thereof

Abstract

The invention provides an environment-friendly material and a preparation method thereof and relates to the field of building materials. The environment-friendly material is prepared from the following raw materials in parts by weight: 32 to 40 parts of expanded perlite, 10 to 16 parts of magnesium oxide, 20 to 30 parts of cement, 15 to 23 parts of urea resin, 0.5 to 0.7 part of sodium dodecylbenzene sulfonate, 3 to 5 parts of an anion additive, 12 to 14 parts of quartz sand, 22 to 32 parts of vermiculite, 14 to 20 parts of waste polyethylene foamed plastic, 8 to 12 parts of attapulgite, 6 to 12 parts of diatomite, 13 to 17 parts of nanometer titanium dioxide, 5 to 13 parts of ceramic fibers, 13 to 21 parts of polypropylene fibers, 12 to 14 parts of phenolic foam, 0.2 to 0.6 part of a binder, 0.5 to 1.1 part of a heat stabilizer, 0.3 to 0.7 part of an antioxidant, 0.2 to 0.6 part of a retarder, 0.5 to 0.7 part of a water reducing agent and 6 to 10 parts of water. The preparation method comprises the following steps: firstly, weighing the raw materials; secondly, roasting the vermiculite; thirdly, stirring; fourthly, casting moulding, demolding, stacking and curing. The environment-friendly material prepared by the preparation method provided by the invention has the advantages of high compressive strength, high tensile strength, high heat preservation and insulation properties and high energy-saving and environment-friendly properties.
