Problems solved by technology

For example: extruded board, polypropylene foam board, polystyrene board and polyurethane board, etc. The source of the base material of this foam insulation board is petrochemical products, which not only consumes a lot of energy, but also causes a shortage of raw material resources. Rather than energy saving, and the production process is complicated, the cost is high, and there are insurmountable natural defects: not resistant to high temperature, easy to burn, poor anti-aging, releasing toxic and harmful substances, etc.
At the same time, these insulation boards also have a small heat storage coefficient and cannot realize the functions of absorbing, storing and releasing heat energy.
The inorganic thermal insulation materials are mainly vitrified microbead thermal insulation mortar and rock wool. Although the inorganic thermal insulation materials themselves are non-combustible materials and have good adhesion to the wall, their thermal conductivity is generally large and their water absorption is average. Lack of management, foam concrete, rock wool, expanded perlite, etc. have great differences in performance during use, and it is difficult to meet the fundamental requirements of building energy conservation, and some even fail to meet the specification requirements

Description

technical field [0001] The invention relates to the technical field of thermal insulation boards for building walls, in particular to an ultrafine fiber composite molded thermal insulation board and a preparation method thereof. Background technique [0002] With the development of our country's economy, the problem of energy shortage is becoming more and more prominent, and the waste of building heating is serious. Building energy conservation has become an important topic. At present, the insulation materials used in the market are divided into two types: organic insulation materials and inorganic insulation materials. Most of the traditional organic insulation materials are foam insulation boards made of organic polymer materials such as plastics and rubber. For example: extruded board, polypropylene foam board, polystyrene board and polyurethane board, etc. The source of the base material of this foam insulation board is petrochemical products, which not only consumes a ...
