Abstract

The invention relates to a method for producing an environment-friendly composite building material by utilizing industrial solid wastes. The method comprises the following steps: a, drying the industrial solid wastes and then pulverizing the industrial solid wastes by using a pulverizer until the granule diameter is less than 1mm; b, adding 10% of modified organic-inorganic composite binder taken as a binding material, 5% of chlorinated paraffin, 5% of octyl epoxy stearate and 10% of dimethyl isophthalate taken as a plasticizer into 70% of industrial solid waste granules and evenly stirring; c, plastifying the evenly-stirred materials in a rolling manner by using a plasticator so as to obtain a clinker billet, discharging the clinker billet from the plasticator and put into a prefabricated pressure mould and drying for 10 to 20 minutes under the pressure of 400 tons and at the temperature maintained within 90 DEG C to 100 DEG C, thereby obtaining the environment-friendly composite building material. The environment-friendly composite building material is wide in application range and good in economic and social benefits. When the environment-friendly composite building material is applied to the nonbearing wall of an energy-saving building, the performance of the environment-friendly composite building material is superior to the current national standard; and the friendliness of a natural environment and the recycling of resources are realized.

Description

technical field [0001] The invention belongs to the field of building materials and the field of resource recycling, and in particular relates to a method for producing environmentally friendly composite building materials by using industrial solid waste. Background technique [0002] Industrial solid waste, also known as industrial waste or industrial waste, refers to various waste residues, dust and other solid wastes discharged during the production activities of machinery, light industry and other industrial and mining enterprises. Such as acid and alkali sludge in the chemical industry, waste foundry sand in the machinery industry, activated carbon slag in the food industry, fiber shavings of animals and plants in the fiber industry, brick and tile fragments in the silicate industry, etc. This kind of solid waste is huge in quantity, complex in composition and various in variety. With the development of industrial production, the amount of industrial waste is increasin...
