Embodiment 1

[0040] 1. Take 40 parts of montmorillonite with a particle size of 100-120µm and 15 parts of nano-titanium dioxide particles with a particle size of 15-20nm and mix them evenly in a high-speed mixer, add 500 parts of CTAB aqueous solution (the mass concentration of CTAB is 10%) After stirring evenly, add 15 parts of titanium tetrachloride (CAS7550-45-0, AR, purchased from Aladdin, product number T104376) to obtain suspension A; add ammonia water with a mass concentration of 20% to suspension A , adjust the pH to 8, and react under stirring conditions. After the reaction is completed, a suspension B is obtained; the suspension B is centrifuged to obtain a sediment, and water is added to the sediment to repeat the centrifugation process several times, and the sediment is cleaned until The pH was 7; then the precipitate was dispersed in water, 40 parts of hydrogen peroxide with a mass concentration of 35% was added for oxidation reaction, and a composite hydrogel was obtained afte...

Abstract

The invention discloses an environmentally-friendly composite mineral thermal-insulation board and a preparation process thereof, belonging to the technical field of building materials. The compositemineral thermal-insulation board includes the following components: 15 to 85 parts of non-metallic minerals, 6 to 85 parts of expanded polystyrene, 0.3 to 26 parts of polystyrene fibers, 0.5 to 28 parts of titanium dioxide aerogel, and 3 to 23 parts of nanometer titanium dioxide particles. The preparation process comprises the following steps: preparing a composite aerogel composed of the nanometer titanium dioxide particles, the non-metallic minerals and titanium dioxide, and then subjecting the obtained mixture and polystyrene foam beads to heating and foaming so as to obtain the environmentally-friendly composite mineral thermal-insulation board. The thermal-insulation board has a large number of pores, rich pore structures, and good thermal insulation, sound insulation and flame retardant properties, and can meet the demands of building construction.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an environment-friendly composite mineral insulation board and a preparation process thereof. Background technique [0002] The development of the construction industry has promoted the continuous diversification and functionalization of building materials. Building insulation boards are usually used for thermal insulation and heat insulation of building exterior walls. They are a new type of environmentally friendly and energy-saving building materials. Foamed asbestos board is an insulation board material commonly used in the early days. It has high fire resistance and high thermal insulation performance, and has a good insulation effect. However, long-term exposure to asbestos fibers will cause respiratory diseases and skin diseases. my country has basically banned the use of asbestos insulation boards. At present, the insulation boards commonly used in ...
