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 resis

Abstract

The invention relates to a phase change energy storage plant fiber composite heat insulation board and a preparation method of the composite heat insulation board; the phase change energy storage plant fiber composite heat insulation board is prepared from the raw materials in parts by weight: 30-50 parts of phase-change material and 50-70 parts of plant fiber, wherein the phase-change material is one selected from mirabilite, calcium chloride hexahydrate, n-caprylic acid and butyl stearate; crop straw, straw or Chinese alpine rush is adopted as the plant fiber, so that the local materials can be used, the waste straw resource is utilized, and the waste is changed into valuable; the energy storage characteristic of the phase-change material is combined, so that energy conservation and consumption reduction are realized; and the produced composite heat insulation board has the advantages of being fireproof, flame retardant, light in mass, high in compression strength, good in energy-saving effect, non-toxic, harmless and environment-friendly, and has the functions of heat insulation and sound insulation.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation boards for building walls, and in particular relates to a phase-change energy storage plant fiber composite 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 produ...
