Description
Technical Field
The invention belongs to the technical field of coatings, and particularly relates to a microcapsule slow-release natural plant fragrance functional coating.
Background
With the rapid development of the current society, the requirement of people on living comfort level is increasingly improved, and the living environment with health and environmental protection is concerned and paid more attention. According to relevant statistics, about 70% of the life time of human beings is spent indoors, so that indoor air quality becomes a hot spot of people. More than 300 indoor air pollutants are discovered, and more than 20 indoor air pollutants are easily harmful to human bodies and even carcinogenic, so that the healthy life of the human bodies is greatly threatened. In recent years, people pay more attention to the influence of indoor air quality on the health of people, and more attention is paid to the health and environmental protection of decoration materials. In addition to the basic decorative properties of coatings, consumers are increasingly concerned about their environmental protection properties, including the presence of toxic and harmful substances such as formaldehyde, VOCs, etc., and their ability to optimize the air quality of the indoor environment.
in daily life, natural plant essential oil is used more and more, and the method is a method for effectively optimizing indoor environment. The plant essential oil has effects in preventing infectious diseases, resisting bacteria, viruses, and mold, preventing inflammation, preventing spasm, promoting cell metabolism, and promoting cell regeneration. Some plant essential oils can regulate endocrine organs, promote hormone secretion, and have positive effects on physiological and psychological activities of human body. For example, the lavender essential oil not only has physiological effects of relieving pain, resisting convulsion, diminishing inflammation, resisting rheumatism, resisting bacteria and the like, but also has psychological effects of helping sleep, soothing mood and the like; the white orchid essential oil has the effects of reducing blood pressure, adjusting heart rate, calming and relaxing nerves and the like; the clove essential oil has the functions of local anesthesia and pain relief; the herba Menthae essential oil has refreshing, pathogenic wind expelling, and antiinflammatory effects.
The natural plant fragrance substance is adopted to improve the indoor air and improve the life quality, and is a great appeal for people all the time. The natural plant fragrant substances such as petals, pollen and the like can not control the color due to the influence of other factors such as the pH value of the coating and the environment, and the application of the natural plant essential oil is limited to a certain extent due to the defects that the natural plant essential oil cannot be stably dissolved in the water phase for a long time, the mixture stability is poor, the volatilization speed is high and the like. The slow-release type fragrance nanometer material with the cylindrical or layered structure can effectively solve the problems of solubility and volatilization stability of plant essential oil, can control and adjust the color of the coating, but has larger granularity and unsmooth surface, so that the washing and brushing resistance of the coating is reduced to a certain extent, and only first-class products can be obtained by directly adopting the material. Further pulverization of the material is required, and the inclusion structure is destroyed to some extent.
