Abstract

The invention relates to a foamed basalt insulation material and a preparation method thereof, which belong to the field of the insulation material. The foamed basalt insulation material is prepared by the following main components in parts by weight: 50-90 parts of basalt ore, 0.3-10 parts of a foaming agent, 5-25 parts of a fluxing agent, 3-10 parts of a foam stabilizer, 0.1-0.5 parts of a dispersant, and 0.1-0.7 parts of an auxiliary material, The foamed basalt insulation material is prepared by the steps of crushing, ball milling, spray drying, and foaming. The foamed basalt insulation material is the inorganic non-metallic material having excellent performance, has the advantages of no toxicity and no radiation, low heat conduction coefficient, good thermal insulation performance, andstable chemical property, wherein the pH value is 7-8, the foamed basalt insulation material is neutral or weakly alkaline, and has no corrosion on the metal materials such as carbon steel, stainlesssteel and aluminium; refractiveness is good, the melting point is higher than 1200 DEG C, and a fireproof grade can reach a A-grade standard; and the compressive strength and shearing intensity are high.

Description

technical field [0001] The invention belongs to the field of thermal insulation materials; in particular, it relates to a foam basalt thermal insulation material and a preparation method thereof. Background technique [0002] For the energy-intensive Chinese economy, due to the rapid economic growth, the demand for energy is becoming increasingly urgent, and the situation of energy conservation is not optimistic. Under the condition of limited energy, how to maximize the efficiency of energy use has become a common problem faced by the whole society. Building energy consumption, which accounts for about 30% of the total energy of the whole society, has become the main aspect of energy consumption in our country. Of all the buildings currently owned by our country, only 4% of them have adopted energy-saving measures. Due to the increasingly prominent contradiction between energy supply and demand, the energy situation is still very severe, and energy shortage has become a b...
