Problems solved by technology

Traditional clay bricks and blocks not only waste a lot of energy in the firing process, but also seriously destroy cultivated land, waste land resources, and the harmful gases and dust emitted will also pollute the environment and bring great harm to people's health
Moreover, its energy-saving effect is relatively poor, so traditional clay bricks and blocks have been banned or restricted in most areas, and energy-saving, green and environmentally friendly building insulation boards will be more and more used

Embodiment 1

[0010] Dry the corn stalks naturally, and add electric heating to dry them, so that the moisture content in the stalks is below 5%, crush the dried corn stalks to a length of 5-10 mm, mix the crushed corn stalks with polystyrene raw materials The particles are mixed according to the mass ratio of 15:1, the mixture is added to the plate mold, and the water vapor at 100°C is passed through the mold to make the polystyrene foam, and the straw and polystyrene particles are adhered to each other to obtain light weight. High-quality building energy-saving insulation board, the thermal conductivity of the insulation board is 0.054W / m 2 K.

Embodiment 2

[0012] Dry the corn stalks naturally, and add electric heating to dry them, so that the moisture content in the stalks is below 5%, crush the dried corn stalks to a length of 5-10 mm, mix the crushed corn stalks with polystyrene raw materials The particles are mixed in a mass ratio of 20:1, the mixture is added to the plate mold, and the water vapor at 100°C is passed through the mold to make the polystyrene foam, and the straw and polystyrene particles are adhered to each other to obtain light weight. High-quality building energy-saving insulation board, the thermal conductivity of the insulation board is 0.071W / m 2 K.

Embodiment 3

[0014] Dry the corn stalks naturally, and add electric heating to dry them, so that the moisture content in the stalks is below 5%, crush the dried corn stalks to a length of 5-10 mm, mix the crushed corn stalks with polystyrene raw materials The particles are mixed in a ratio of 30:1 by mass, and the mixture is added to the plate mold, and the water vapor at 100 ° C is passed through the mold to make the polystyrene foam, and the straw and polystyrene particles are adhered to each other to obtain a light weight. High-quality building energy-saving insulation board, the thermal conductivity of the insulation board is 0.097W / m 2 K.

Abstract

The invention relates to a manufacture method for stalk-polystyrene compounding warming plate that includes the following steps: insolating the corn stalk, drying to make the water content below 5%, smashing the corn stalk to 5-10mm, mixing with polystyrene raw material according to weight ratio of 15-30:1, adding the mixture into plate mould, adding 100 degree centigrade vapor into mould to make polystyrene foaming, the light construction energy saving plate.

Description

technical field [0001] The invention relates to a preparation method of a building energy-saving material, in particular to a preparation method of a straw-polystyrene composite thermal insulation board. Background technique [0002] With the increasing global energy and resource crisis, people pay more and more attention to building energy conservation. Traditional clay bricks and blocks not only waste a lot of energy in the firing process, but also seriously destroy cultivated land, waste land resources, and the harmful gases and dust emitted will also pollute the environment and bring great harm to people's health. Moreover, its energy-saving effect is relatively poor, so traditional clay bricks and blocks have been banned or restricted in most areas, and energy-saving, green and environmentally friendly building insulation boards will be more and more used. Contents of the invention [0003] The purpose of the present invention is to provide a method for making a buil...
