Abstract

The invention belongs to the technical field of thermal insulation materials, and provides a non-burning and non-steaming foam thermal insulation composite material, which uses waste porcelain powder, red mud and cement as the gelling material, and the slurry formed after adding water can harden in air or water, and can The components are glued together to form a composite material; by adding a foaming agent, the gelled material forms pores while hardening, combined with the use of a foam stabilizer, the composite material contains a large number of stable pores, thereby improving the performance of the composite material. The thermal insulation performance of the composite material reduces the thermal conductivity of the composite material; by adding an activator to stimulate the active substances in the cementitious material to react, the adhesion of each component is promoted, and the cement is beneficial to promote hardening, thus eliminating the need for sintering and autoclaving , the foam insulation composite material with small thermal conductivity can be obtained by curing at room temperature. The results of the examples show that the thermal conductivity of the non-burning and non-steaming foam insulation composite material provided by the present invention is 0.044W / (m·K).

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a non-burning and non-steaming foam thermal insulation composite material and a preparation method thereof. Background technique [0002] my country is the world's largest producer of ceramics. However, a large number of ceramic wastes are also produced during the mass production of ceramics. The annual production of ceramic polishing wastes from the national ceramic polishing tile production line has reached more than 10 million tons. The accumulation of a large number of ceramic wastes not only occupies Land resources, and open-air stacking can easily lead to dust and contamination of groundwater, so the problem of utilization of ceramic waste is becoming more and more prominent. [0003] At present, the utilization of ceramic waste mainly has the following two ways: recycling and digestion, recycling ceramic waste as mineral raw material to make ceramic slu...
