Embodiment 1

[0049] Embodiment 1, prepare composite waterproof board 1

[0050] At room temperature, the mass ratio of binder—maleic anhydride (technical grade), phthalic anhydride (technical grade), propylene glycol (technical grade), styrene (technical grade) is 10:15: Mix 100g of a 10:30 mixture with 2g of hydrogen peroxide evenly, and then mix with 100g of wheat straw with a length of 5-20 mm to make a pre-molding material; pour 100g of power plant fly ash (300 mesh) into this In the pre-molding pressing material, mix evenly to make the molding pressing material.

[0051] In order to facilitate demoulding, brush a small amount of engine oil in the mold, take 130g of molding compound and fill it into the cavity, press it flat with your hands, cover the mold and press the template for compaction. Heat the upper and lower heating plates of the flat vulcanizing press to 110°C, and pressurize the loaded mold to 5MPa in the vulcanizing press, hold the pressure and keep it warm for 10 minute...

Abstract

The present invention relates to a composite water-proof material. It is made up by using (by weight portion) 20-70 portions of plant fibre, 10-60 portions of flyash and 5-40 portions of adhesive through the processes of mixing them, die-pressing and polymerization. The described adhesive is formed from maleic anhydride, phthalic anhydride, polyalcohol, styrene or mixture of their homologous compounds, also can include trimeric cyanamide, acrylic acid or rosin and dicyclopentadiene. Its raw material composition also can include 10-40 portions of new and old plastics. Said plate material has strong strength and good water-proof property, so that it has extensive application range.

Description

technical field [0001] The invention relates to a composite waterproof board and its preparation method and application. Background technique [0002] The furniture manufacturing industry and the building decoration industry need to consume a lot of wood, which has caused a sharp decline in the world's forests and land desertification. Therefore, various countries in the world have introduced various policies to limit forest felling, making the raw materials of the building materials industry scarce. On the other hand, fly ash and straw are two major wastes in today's industrial and agricultural production. According to statistics, the emissions of fly ash and straw in the world are about 160 million tons / year and 2.9 billion tons / year respectively, while in China they are 110 million tons / year and 600 million tons / year. In addition, with the increasing demand for plastic consumption, the total amount of waste plastics is also expanding. The annual production of waste plast...
