However, it is proved that residents in subtropical and temperate regions have seasonal vitamin D deficiency, which means that functional vitamin D is sufficient in summer and insufficient in winter, so that the comprehensive immunity of most of people is relatively low in autumn and winter, and children in the growth period are particularly obvious.
The proper increase of exercise and sunlight irradiation are important factors for promoting the absorption of vitamin D, the effect of exercise in the time period with insufficient sunlight is more important, but with the deepening of the urbanization process in China, the number of urban population is increased, indoor exercise becomes the main exercise means of the urban population, and the household exercise is limited due to the problem of limited floor sound insulation effect.
However, no special sound insulation floor which can adjust the temperature and has comfortable foot feeling is available on the market at present. Acetophenone is colorless crystal below 20 ℃, is light yellow oily liquid above 20 ℃, has the smell of hawthorn, is a plasticizer of cellulose ester and resin, is hydrophobic, oil-resistant, non-toxic and harmless, is a good filler of a sound insulation floor, but does not have related application in the field of sound insulation floors at present. The main defects of the existing sound insulation floor on the market in the application of temperate zone and subtropical zone are that the floor is not water-resistant, has high rigidity and poor flexibility, has hard foot feel, has no damping function and thus has relatively low service life.
Therefore, the oil-proof, waterproof, long-life and environment-friendly sound insulation floor which is intrinsically water-resistant, good in material plasticity, comfortable in foot feeling, sound-proof and vibration-damping and the manufacturing method thereof are urgently needed in the market.
