A reflective heat-insulating sprayable waterproof coating

Abstract

The invention discloses light-reflecting and heat-insulating spraying waterproof paint. The light-reflecting and heat-insulating spraying waterproof paint comprises a component A and a component B, wherein the component A is prepared from raw materials including, by weight, 65-70 parts of an EVA (ethyleno vinyl acetale copolymetr) emulsion, 5-8 parts of high-refractive-index glass beads, 15-25 parts of reflective quartz powder, 0.3-0.5 part of a flocculant, 0.5-1 part of a stabilizer, 0.2-0.3 part of a dispersing agent, 0.2-0.3 part of a defoamer, 0.15-0.25 part of a bactericide and 5-15 parts of water; the component B is prepared from raw materials including, by weight, 12-25 parts of an accelerator, 3-8.5 parts of an accelerant and 8-14 parts of water. The quartz powder of the porous and high-porosity structure is plated with a high-refractive-index metal oxide nanomaterial to achieve light reflecting effect together with high-refractive-index glass beads which are lightweight, low in heat conductivity, high in tensile strength and good in chemical stability, heat-insulating performance of the waterproof paint is enhanced, environment protection is achieved, construction can be performed by means of spraying, construction efficiency is improved, and working intensity is lowered.

Description

【Technical field】 [0001] The invention relates to the technical field of architectural waterproof coatings, in particular to a reflective heat-insulating waterproof coating that can be sprayed. 【Background technique】 [0002] Architectural waterproof coating is a viscous liquid polymer synthetic material with no fixed shape at room temperature. After coating, it can form a tough waterproof coating film on the surface of the base layer after the volatilization of solvent or water evaporation or reaction curing. the general term for. At present, the functionality of architectural waterproof coatings is relatively single, with the effect of waterproof and water insulation, but the effect of reflective heat insulation is poor. [0003] Due to sunlight, the indoor temperature of the building will rise rapidly, and the indoor ventilation effect is poor, resulting in poor heat dissipation, increasing the use of air conditioners, and serious energy consumption. Human health and th...
