Novel insulation material and preparation method thereof

Abstract

The invention provides a novel insulation material and a preparation method thereof, and relates to the technical field of building materials. The novel insulation material comprises the following raw materials in parts by weight: 30-50 parts of retinte glass microbeads, 3-5 parts of light magnesium oxide, 0.7-1.1 parts of sodium fluosilicate, 0.4-0.6 part of aluminum dihydrogen phosphate, 0.2-0.6 part of polyvinyl alcohol, 0.5-0.7 part of kaolin, 2-4 parts of fly ash, 2-3 parts of attapulgite, 10-16 parts of sepiolite powder, 1-3 parts of sodium succinate sulfonate, 12-16 parts of cement, 5-13 parts of rock wool, 6-8 parts of phenolic foam, 11-15 parts of flexible ceramic, 3-7 parts of ceramic fiber, 5-11 parts of polyester fiber, 10-20 parts of vermiculite, 2-6 parts of polyethylene foam plastic, 0.3-0.9 part of a heat stabilizer, 0.2-0.6 part of a water reducing agent, 0.1-0.5 part of a bonding agent, 0.2-0.4 part of a foaming agent and 4-8 parts of water. The preparation method comprises the following steps: (1) weighing the raw materials; (2) roasting the vermiculite; (3) stirring; (4) adding into a mould, moulding and curing. The novel insulation material prepared by the preparation method provided by the invention has the advantages of good sound isolation, high tensile strength, high compressive strength and good insulation.
