Abstract

The invention relates to a bamboo cuttings and powder coal composite water-proof plate and a method for manufacturing the same, the composite water-proof plate is made by blending, press molding and polymerizing 20 to 70 potions by weight of bamboo cuttings, 10 to 60 potions by weight of powder coal, 5 to 40 potions by weight of adhesive and TAIC. The compositions of bamboo cuttings and powder coal composite water-proof plate provided by the invention can also comprises 1 to 12 potions by weight of new and old plastic materials. The bamboo cuttings and powder coal composite water-proof plate has high intensity and favorable water-proof performance; most of the raw materials adopted are the scrap products in industry and agriculture, thereby the environment pollution can be degraded. The bamboo cuttings and powder coal composite water-proof plate can be widely used in the floor manufacturing industry, the furniture industry, the decoration and construction material industry as well as the inner decoration material in automobile industry.

Description

technical field [0001] The invention relates to a preparation method and application of a waterproof board, in particular to a waterproof board made of bamboo chips and fly ash and a preparation method thereof. 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 bamboo chips are two major wastes in today's industry and bamboo processing. According to statistics, the world's fly ash emissions are about 160 million tons per year, and China's is about 110 million tons per year; there are currently more than 50 genera and more than 1,200 species of bamboo plants in the world, and the bamboo forest area is 22 million hecta...
