Problems solved by technology

[0005] After the 1980s, the world's climate became warmer and energy sources were increasingly exhausted. Under the dual pressures of environmental protection and energy sources, new requirements were brought to external wall insulation, which required both good thermal insulation performance and high flame retardancy. External wall insulation materials are mainly organic materials such as polystyrene and polyurethane. These materials have good thermal insulation performance and construction performance, and the cost is relatively low. However, these materials have fatal shortcomings and are easy to burn. The combustion performance is B2

Abstract

The invention discloses a production method for producing a heat insulation board for a vacuum heat insulation wall body by utilizing small expanded and vitrified balls, and the method comprises the following steps: putting the small expanded and vitrified balls, glass fiber, silica fume, bentonite and a getter into a stirring kettle, adding a wetting agent and a bonding agent, and stirring for forming a paste-like material; uniformly spreading the well stirred paste-like material on a micro-wave baking line according to the required thickness for baking, and further cutting into blocks when the water content in the board is below 1%; further placing the board which is cut into the blocks on a vacuum machine assembly line and vacuum pumping till the vacuum degree is below 200Pa; and cutting and packaging the heat insulation board for the vacuum heat insulation wall body. By applying the method provided by the invention for production, the process is simple, the emission of three wastes can be avoided, the produced heat insulation board for the vacuum heat insulation wall body is easy to construct, the fireproof property can be realized, the heat insulation board for the vacuum heat insulation wall body can play great roles in heat preservation and heat insulation, the combustion performance is grade A, the weight is light, the weather-resistant time is long, and the service life can be above 30 years.

Description

technical field [0001] The invention relates to a method for producing a vacuum heat insulation wall insulation board by using expanded vitrified microspheres and other heat insulation materials, and belongs to the technical field of building material production. Background technique [0002] Vacuum insulation panel is a kind of vacuum insulation material, which is composed of filling core material and vacuum protection surface layer. It can effectively avoid heat transfer caused by air convection, so the thermal conductivity can be greatly reduced, less than 0.006w / m.K, And it does not contain any ODS materials, and has the characteristics of environmental protection and high efficiency and energy saving. It is currently the most advanced high-efficiency thermal insulation material in the world. Compared with traditional insulation materials, vacuum insulation panels can meet the same thermal insulation technical requirements, and have the advantages of thin layer, small si...
