NOVELTY - Long-acting deodorizing and spraying liquid comprises 0.5-2 pts. wt. thermal catalyst, 0.5-2 pts. wt. β-cyclodextrin, 5-10 pts. wt. common soil, 5-10 pts. wt. calcium carbonate, 5-10 pts. wt. agglomerant, 3-10 pts. wt. starch, 5-10 pts. wt. phase-change temperature-adjusting microcapsule, 0.1-0.5 pts. wt. photovoltaic power generation material and 30-40 pts. wt. solvent. USE - Used as long-acting deodorizing and spraying liquid. ADVANTAGE - The spraying liquid: forms coating in chamber; and utilizes the phase-change temperature adjusting microcapsules to increase the coating temperature at low temperatures even in the case of weak light, and utilizes photovoltaic power generation materials to assist in catalytic effect of thermal catalysts, so as to achieve the purpose of long-term degradation of volatile organic compound and purification of indoor air. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the spraying liquid, comprising (i) placing the paraffin in organic solvent, heating to a molten state at 70-80℃, cooling to room temperature, then adding n-heptadecane, uniformly stirring to obtain a composite core material solution, dissolving the emulsifier with water to form an emulsifier solution, adding the composite core material solution and wall material into the emulsifier solution, stirring at a low speed and performing high-speed shearing and emulsifying dispersion, placing emulsifying and dispersing reaction system in an ultrasonic wave, dripping initiator, and filtering and drying to obtain the phase-change temperature adjusting microcapsule, (ii) taking the solvent, adding thermal catalyst, calcium carbonate, starch, β-cyclodextrin and photovoltaic power generation materials, uniformly stirring at high speed, then adding phase change temperature adjusting microcapsules, and uniformly stirring at high speed again, and (iii) grinding common soil into powder, adding to the agglomerant, uniformly stirring, adding to the system in the step (ii), emulsifying and dispersing with high-speed shearing to obtain the finished product.
