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.
Some farmers simply incinerate or pile up at random. This treatment method not only wastes precious natural resources, but also brings various hazards, causing air pollution and frequent traffic accidents, etc., which is harmful to human health and the ecology of surrounding animals and plants. serious impact on the environment

Abstract

The invention relates to a thermal insulation board and a preparation method thereof. It is prepared from the following raw materials in parts by weight: 30 to 50 parts of phase change materials and 50 to 70 parts of plant fibers. Any one phase change material in calcium, n-octylic acid and butyl stearate; the plant fiber adopts crop straw, or rice straw, or asparagus, which can be obtained locally, and waste straw resources can be used to turn waste into Combining the energy storage characteristics of phase change materials to achieve energy saving and consumption reduction, the production has the advantages of fire and flame retardancy, light weight, high compressive strength, good energy saving effect, thermal insulation and sound insulation, non-toxic and harmless, and green environmental protection. .

Description

technical field [0001] The invention belongs to the technical field of thermal insulation boards for building walls, and in particular relates to a 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. Existing foam insulation boards on the market are foam insulation boards made of organic polymer materials such as plastics and rubber as base materials. 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, an...
