A radiation-proof heavy aggregate prepared from waste and its preparation method

Abstract

The invention relates to a radiation-proof heavy aggregate prepared from waste and a preparation method thereof. The radiation-proof heavy aggregate is made of the following raw materials in weight percentage: 30-35% of waste cathode ray tube glass, 15-5% of barium mud 20%, high-iron red mud 40-45%, and coke powder 10-15%; when preparing the radiation-proof heavy aggregate, weigh the raw materials according to the above ratio, then crush or grind the raw materials separately, and then fully Mix and pelletize, then dry the pelletized green body, then roast the dried green body in sections to make it fully react, and finally take it out of the furnace when it cools down to 250-350°C Obtain radiation-proof heavy aggregate. The anti-radiation heavy aggregate of the present invention uses red mud, barium mud and waste cathode ray tube glass as the main raw materials, and replaces relatively expensive and scarce barite, which can reduce the dependence of my country's building material industry on barite, and ease the rapid development of industries. The crisis of lack of high-quality barite brought about by development.

Description

A kind of radiation protection heavy aggregate prepared by using waste and preparation method thereof technical field The invention belongs to the heavy aggregate manufacturing technical field, be specifically related to a kind of radiation protection heavy aggregate prepared by utilizing waste and its preparation method. Background technique In recent years, display technology has developed rapidly, and liquid crystal display technology and plasma display technology are more Polar ray tube display technology has greater advantages, so the waste cathode ray tube heavy metal glass on computers and TV sets in my country Rapid growth in volume. CRT glass often contains heavy metals such as barium and lead, which can seriously harm human health if not disposed of properly. health and ecological environment. Therefore, the comprehensive treatment and secondary utilization of CRT waste glass becomes very important. Residual solid is called barium mud in the barium salt...

Problems solved by technology

However, with the continuous development of industry, high-quality, single-type barite mines are increasingly depleted. At present, most of the barite mines in my country are of low grade, which makes barite concrete raw materials very scarce.
