Anion thermal insulation building material

Abstract

The invention discloses an anion thermal insulation building material which comprises the following raw materials in parts by weight: 30-50 parts of expanded perlite, 10-30 parts of magnesium oxide, 10-30 parts of Portland cement, 10-30 parts of urea resin, 0.5-1.5 parts of sodium dodecyl benzene sulfonate and 4-6 parts of anion additive. The anion thermal insulation building material disclosed by the invention has relatively good thermal insulation property and can effectively release anions to purify air and eliminate indoor odor and various harmful gases.

Description

technical field [0001] The invention relates to a building material, in particular to a negative ion thermal insulation building material. Background technique [0002] Insulation materials are generally materials with a thermal coefficient less than or equal to 0.2. The development of thermal insulation materials is rapid, and the use of good thermal insulation technology and materials in industry and construction can often achieve twice the result with half the effort. Every ton of mineral wool insulation products used in buildings can save one ton of oil a year. [0003] The thermal insulation material can collect excess heat and release it in a timely and stable manner, with small gradient changes, which can effectively reduce the loss. The room temperature can be trended and the winter heat preservation can play a balancing role. In the decoration of new buildings and the renovation of old buildings, it can overcome the congenital disadvantages of wall cracks, condens...
