[0033] The invention provides a method for preparing nano temperature-controlled slow-release aromatic microcapsules, comprising the following steps:
[0034] (1) Preparation of raw materials: the nano-temperature-controlled slow-release aromatic microcapsules include the following raw materials in weight fractions, 20-60 parts of phase change material carrier, 20-60 parts of essence, 30-90 parts of monomer, 0.3- 1.0 parts of initiator, 3-6 parts of emulsifier and 200-600 parts of water;
[0035] (2) Preparation of core material components: Mix the phase change material carrier and essence in the above ratio in a closed container at 30-35°C at 800-1200r / min to form a core material component;
[0036] (3) Preparation of oil phase components: Stir and mix the core material components prepared in (2) with the monomer and initiator in (1) in a closed container at 30-35° C. to form oil phase components;
[0037] (4) Preparation of water phase components: Stir and activate the emul...
