Embodiment 1

[0020] The plant straw-containing thermal insulation brick composed of the raw materials in the following proportions by weight:

[0021] 70 parts of plant straw, 20 parts of magnesium hydroxide, 10 parts of isocyanate,

[0022] Preparation method: crush plant straw with a moisture content of 15% by weight into fibers with a length of 5 to 10 mm, dry until the moisture content is 8% by weight, weigh the plant straw according to the weight percentage, and press Add magnesium hydroxide and binder isocyanate to the parts by weight, stir and mix ingredients, and then pre-press, the pre-press pressure is 500 tons, and then mold compression molding, the molding pressure is 1.2 thousand tons, using high-frequency electromagnetic induction Method, heating to 110 ° C, hot pressing for 4 to 5 minutes to shape.

Embodiment 2

[0024] The plant straw-containing thermal insulation brick composed of the raw materials in the following proportions by weight:

[0025] 80 parts of plant straw, 15 parts of magnesium hydroxide, 5 parts of isocyanate,

[0026] Preparation method: adopt high-frequency electromagnetic induction method, heat to 110°C, hot press for 4-5 minutes to form, and the rest of the method and steps are the same as in Example 1.

Abstract

The invention relates to a preparation method of an insulating brick containing plant straws. The preparation method is characterized in that the insulating brick is produced from the raw materials in parts by weight: 70-80 parts of the plant straws, 13-25 parts of magnesium hydroxide and 5-10 parts of isocyanate and comprises the steps: crushing the plant straws to obtain crushed plant straws with the fiber length of 5-10mm, drying the crushed plant straws until the moisture content is 8 percent according to the weight percentage, weighing the plant straws according to the parts by weight, adding the magnesium hydroxide and the isocyanate as a binder according to the parts by weight, carrying out mixing and burdening, then carrying out prepressing with the precompression of 500 tons, then carrying out compression molding with the die pressure of 1.2 kilotons, heating to 110 DEG C by virtue of a high-frequency electromagnetic induction method, and carrying out hot pressing for 3-6 minutes to form the insulating brick. According to the production method disclosed by the invention, with the plant straws as main raw materials, the produced insulating brick has a good fireproof performance without needing secondary insulation; in addition, the insulating brick is rapid in construction, has a favorable anti-seismic effect and has the shock strength according with the stipulations of a national standard in wall materials.
