Abstract

The invention relates to glass fiber heat insulating cotton taking gold copper tailings as a main raw material and a preparation method of the glass fiber heat insulating cotton. The raw materials of the glass fiber heat insulating cotton comprise the following components in percentage by weight: 65-75 percent of gold copper tailings, 15-25 percent of quartz sand, 3-5 percent of sodium borate, 2-5 percent of sodium carbonate and 1-2 percent of titanium dioxide. The raw materials are mixed in proportion to prepare the glass fiber heat insulating cotton through an electric smelting crucible wire drawing method in combination with a jetting method. The density of the glass fiber heat insulating cotton prepared from the gold copper tailings is in a range of 20 to 120 kg / m<3>, the normal-temperature heat conductivity coefficient is in the range of 0.03 to 0.10 W / (K.m), and the glass fiber heat insulating cotton can achieve the effects of sound insulation, sound absorption, heat preservation, moisture resistance and heat insulation, is simple in production process, relatively low in cost and capable of consuming lots of waste tailing materials, can have the effects of changing wastes into valuable materials and protecting the environment, and has high added value of products.

Description

technical field [0001] The invention relates to a glass fiber thermal insulation cotton with gold-copper tailings as the main raw material and a preparation method thereof, belonging to the field of building materials. Background technique [0002] A large number of mines have been mined around the world, resulting in a huge amount of abandoned tailings, which has caused serious impact and damage to the ecological environment, and it will take a long time to restore the environment. Also with the rapid development of my country's national economy, the demand for various mineral resources has increased sharply, and a large amount of solid waste will inevitably be produced. According to statistics from relevant departments, the comprehensive utilization rate of associated mineral resources is less than 20%, and the total recovery rate of mineral resources is only 30%. Even if some large state-owned mining enterprises have carried out comprehensive resource utilization, it only...
