Abstract
The invention discloses a low-cost environmental-friendly composite heat-insulating mortar which is characterized by being prepared from the following raw materials in parts by weight: 9-12 parts of volcanic scoriae, 25-29 parts of small expended and vitrified balls, 38-42 parts of portland cement, 7-9 parts of phosphogypsum, 4-6 parts waste brick dregs, 2-3 parts of palm fibers, 4-6 parts of crushed coconut shells, 3-4 parts of cotton seed hull, 2-3 parts of aluminum hydroxide, 0.8-1 parts of silane coupling agents KH-580, 14-18 parts of pottery clay, 2-3 parts of polyacrylamide and 8-10 parts of synergists. The low-cost environmental-friendly composite heat-insulating mortar disclosed by the invention can be used for enhancing the property of small vitrified balls by matching the addition of the phosphogypsum, the waste brick dregs and the like and the addition of natural components, namely the cotton seed hull, the crushed coconut shells and the like, with the addition of light-weight aggregates, namely the volcanic scoriae, the pottery clay and the like, and has good crack resistance and high-temperature resistant property through the addition of synergists prepared from crop straw base materials, thus enhancing the fire prevention and fire retardance of a product. The low-cost environmental-friendly composite heat-insulating mortar disclosed by the invention has the advantages of good heat-insulating effect, energy conservation, low cost and convenient construction.
Description
technical field [0001] The invention relates to the field of building thermal insulation materials, in particular to a low-cost environment-friendly composite thermal insulation mortar and a preparation method thereof. Background technique [0002] The large stockpiling of phosphogypsum not only encroached on land resources, but also polluted the atmosphere, water system and soil due to wind erosion and rain erosion. Due to the process of urbanization, large-scale demolition work is underway, which has resulted in a large amount of construction waste, especially discarded bricks and slag, which not only affects the city appearance, but also causes a waste of resources. The present invention adds these two components to the manufacture of the thermal insulation mortar, which can not only turn waste into treasure, but also enhance the compressive strength of the thermal insulation mortar and reduce the bulk density. [0003] The invention intends to make a low-cost environmen...
