Embodiment 1

[0010] For microencapsulated air freshener, mix and stir 3g of sodium alginate and 100mL of water while heating to 60°C to completely dissolve the sodium alginate in water, continue to stir and gradually cool to 40°C, add 0.3mL of mint essential oil, tea tree A mixture of essential oil and lemongrass essential oil (the weight ratio of peppermint essential oil, tea tree essential oil and lemongrass essential oil is 3:4:4), the mixed essential oil is evenly dispersed in the solution, and then slowly lowered to room temperature and formed Sodium alginate-essential oil microcapsules, then add sodium alginate-essential oil microcapsules weight 0.5% chitosan wall material, and add sodium alginate-essential oil microcapsules weight 0.2% glycerol, finally form chitosan, A microencapsulated air freshener that uses sodium alginate as the wall material and peppermint essential oil, tea tree essential oil and lemongrass essential oil as the core material.

Embodiment 2

[0012] For microencapsulated air freshener, mix and stir 8g of sodium alginate and 100mL of water while heating to 70°C to completely dissolve the sodium alginate in water, continue to stir and gradually cool to 45°C, add 1.8mL of peppermint essential oil, tea tree The mixed olein (the weight ratio of peppermint essential oil, tea tree essential oil and lemongrass essential oil is 6:4:1) mixed with essential oil and lemongrass essential oil, the mixed essential oil is evenly dispersed in the solution, then slowly lowered to room temperature and formed Sodium alginate-essential oil microcapsules, then add the chitosan wall material of sodium alginate-essential oil microcapsules weight 1.5%, and add sodium alginate-essential oil microcapsules weight 1.0% glycerol, finally form chitosan, A microencapsulated air freshener that uses sodium alginate as the wall material and peppermint essential oil, tea tree essential oil and lemongrass essential oil as the core material.

Embodiment 3

[0014] For microencapsulated air freshener, mix and stir 5g of sodium alginate and 100mL of water while heating to 65°C to completely dissolve the sodium alginate in water, continue to stir and gradually cool to 42°C, add 1.2mL of peppermint essential oil, tea tree Essential oil and lemongrass essential oil are mixed into a mixed olein (the weight ratio of peppermint essential oil, tea tree essential oil and lemongrass essential oil is 1:1:1), and the mixed essential oil is evenly dispersed in the solution, then slowly lowered to room temperature and Form sodium alginate-essential oil microcapsules, then add sodium alginate-essential oil microcapsules weight 1.0% chitosan wall material, and add sodium alginate-essential oil microcapsules weight 0.6% glycerol, finally form chitosan , Sodium alginate as the wall material, peppermint essential oil, tea tree essential oil and lemongrass essential oil as the core material microencapsulated air freshener.

Abstract

The invention discloses a microencapsulated air freshener. A preparation method of the microencapsulated air freshener comprises the following steps: mixing and stirring 3-8g of sodium alginate and 100ml of water, and heating to 60-70 DEG C at the same time; after the sodium alginate is completely dissolved in the water, continually stirring, gradually cooling to 40-45 DEG C, and adding 0.3ml-1.8ml of an essential oil mixture formed by mixing peppermint essential oil, tea tree essential oil and lemongrass essential oil in the weight ratio of 3:4:4 to 6:4:1; and after the essential oil mixture is uniformly dispersed in the solution, slowly cooling to room temperature to form sodium alginate-essential oil microcapsules, adding a chitosan wall material accounting for 0.5wt%-1.5wt% of the sodium alginate-essential oil microcapsules, and adding glycerine accounting for 0.2wt%-1.0wt% of the sodium alginate-essential oil microcapsules, thus finally forming the microencapsulated air freshener taking chitosan and sodium alginate as the wall material and taking the peppermint essential oil, the tea tree essential oil and the lemongrass essential oil as the core material. The microencapsulated air freshener disclosed by the invention has the beneficial effects of good air purifying effect and long lasting time.

Description

technical field [0001] The invention relates to an air freshener, in particular to a microencapsulated air freshener. Background technique [0002] When the indoor air quality is poor, the air is dirty, and there are pungent smells such as oily smoke, not only the unpleasant smell will not only cause people to feel depressed, but also the harmful components in the air may endanger people's health. The use of air fresheners increasingly important. However, the air fresheners in the current market have a short duration and a single effect, and if they are sprayed in large quantities, a lot of waste will be caused. Contents of the invention [0003] The object of the present invention is to solve the above problems and provide a microencapsulated air freshener, which has the advantages of fresh air, clean air, and low cost of use. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] For microencapsulate...
