Abstract

The invention relates to a silicon dioxide composite heat insulating coating and a preparation method thereof. The silicon dioxide composite heat insulating coating comprises a subcoat and a closing layer from bottom to top. The subcoat is prepared from, by weight, 20-25 parts of coarse floating bead particles or coarse sinking bead particles, 80-100 parts of polymer mortar and 5-10 parts of water, and the closing layer is prepared from, by weight, 70-80 parts of fine floating bead particles or fine sinking bead fine particles, 3-8 parts of silicon carbide, 15-25 parts of polymer mortar and 5-6 parts of water. The preparation method is simple, floating beads and sinking beads are adopted as raw materials to prepare the silicon dioxide composite heat insulating coating, the heat resistance of silicon dioxide and silicon carbide is fully utilized, the stability of heat expansion and cold contraction of the polymer mortar is used in cooperation, therefore, the prepared coating cannot crack or fall off whether in spring or summer or autumn or winter under sunlight irradiation, the floating beads and the sinking beads are developed and utilized, energy is saved, and economic benefits 10-20 times those of the raw materials and energy-saving social benefits can be achieved.

Description

technical field [0001] The invention relates to a silica composite thermal insulation coating and a preparation method thereof, and belongs to the technical field of new material preparation. Background technique [0002] Silica is traditionally used in the fields of rubber, ceramics, glass, refractory bricks, oil well drilling lubricating fluid - curing light cement, etc. Due to the mature technology at home and abroad, the added value is relatively low, because of the low technology content. In the National Twelfth Five-Year Plan, emphasis is placed on environmental protection and resource integration and utilization. Energy-saving and emission-reduction, new energy-saving materials with industrial waste as the main raw material developed according to the national industry orientation are mainly used in ultra-high temperature roofs, pipes, and interior and exterior wall coatings, which play the roles of heat insulation, heat conduction, flame retardant, and cooling.
