Boron Boron chemical mud is discharged out of the waste, a huge amount of their emissions, only the cumulative amount of Liaoning Province, has more than ten million tons. Boron Mud strongly alkaline, it is not only large accumulation of farmland and pollute the environment, its development and utilization of boron industry has become an urgent need to solve the problem. Boron Mud current research is focused on leveraging its silicon magnesium composition, preparation materials, production of agricultural fertilizer, for wastewater treatment, extract useful components, preparation refractories. In this thesis, a new type of energy-saving foam material prepared for the target, the use of boron sludge secondary resources such as raw materials through the foam slurry prepared a lightweight porous foam material, and preparation process and material properties were studied . The main contents are as follows: (a) boron mud-based foam material preparation. Boron mud as the main raw material, respectively, using the Add method and the pore foam slurry foaming method were investigated pore-forming agent to the amount of sintering temperature, foam dosage and other important process parameters on materials. Adding method obtained pore foam porosity up to 20% compressive strength than 9.5MPa. Foaming slurry was obtained foam porosity of 69%, a compressive strength of 1.6 MPa, adding glass powder, borax and sodium hydroxide can improve sinterability flux, and the material strength. (2) Boron Mud Preparation of fly ash-based foam. Boron mud and fly ash as the main raw material obtained foams investigated the amount of fly ash added and additives on the material properties; material can be rapid sintering, the density of 0.695g/cm3, apparent porosity of 72.3%. compressive strength of up to 7.91 MPa, thermal conductivity of 0.1866 W / m. K, can be used as thermal insulation materials. (3) removal of magnesium boron mud-based foam material preparation. Magnesium removal of boron in the mud for raw materials foams investigated sintering temperature, foam dosage and base excitation process on the material properties, and analyzes its base excitation mechanism; material porosity was 66.39%, and the apparent density of 0.90 g/cm3, a compressive strength of 6.5 MPa. (4) Boron Mud base unburned magnesium gelling foam preparation. After activation boron mud add curing agent, additives and water slurry foaming method to get through unburned foam investigated CMC as additives influence on the material properties, the material can be used as filling material and the insulation filling material.
