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.

Embodiment 1

[0017] In the phase-change energy-storage inorganic foamed cement insulation board of the present invention, the ratio of each raw material can be: 10 parts of phase-change temperature-adjusting aggregate, 70 parts of cement, 2 parts of silicon dioxide, 3 parts of fly ash, mineral 1 part of fiber, 0.1 part of polypropylene short fiber, 0.5 part of cement foaming agent, and 0.1 part of stabilizer.

[0018] The production of the foam insulation board can be carried out according to the following method: First, take fly ash and silicon dioxide respectively, and crush them through a 300-400 mesh sieve to make powder, so as to enhance its specific surface area and activity, and then press the required According to the above ratio, weigh the phase-change temperature-adjusting aggregate, cement, fly ash powder, silica powder, mineral fiber and polypropylene short fiber, put them into the mixer, add water and stir for 3 to 5 minutes to make them fully mixed , to make a mixed slurry, w...

Embodiment 2

[0020] In the production of the phase-change energy storage foamed cement insulation board of the present invention, the proportioning of each raw material can also be: 12 parts of phase-change temperature-adjusting aggregate, 72 parts of cement, 2.5 parts of silicon dioxide, 4 parts of fly ash, 1.5 parts of mineral fiber, 0.15 part of polypropylene short fiber, 0.8 part of cement foaming agent, and 0.15 part of stabilizer. The production method is basically the same as that of Example 1, except that the amount of water added when preparing the mixed slurry is in a weight ratio: water: total amount of raw materials = 10:3.

Embodiment 3

[0022] In the production of the phase change energy storage foamed cement insulation board of the present invention, the ratio of each raw material can also be: 15 parts of phase change temperature-adjusting aggregate, 75 parts of cement, 3 parts of silicon dioxide, 5 parts of fly ash, 2 parts of mineral fiber, 0.2 part of polypropylene short fiber, 1 part of cement foaming agent, and 0.2 part of stabilizer. Its production method is basically the same as that of Example 1, except that the amount of water added when preparing the mixed slurry is in a weight ratio: water: total amount of raw materials = 10: 3.5.

Abstract

The invention relates to an inorganic composite phase-change energy storage foamed insulation board and a preparation method thereof. The board is prepared by the following eight raw materials: phase-change temperature adjusting aggregates, cement, silicon oxide, fly ash, mineral fibers, polypropylene staple fibers, cement foaming agents and stabilizing agents. The insulation board manufactured by the method of the invention has good heat storage property, waterproofness and ageing resistance, and has the advantages of light weight, strong binding strength, high compression strength, heat insulation, waterproofness and moistureproofness, obvious energy saving effect, etc.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation boards for building walls, and relates to a phase-change energy storage inorganic foam 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 production proce...
