Abstract

The invention discloses a slow release type solid aromatic. The slow release type solid aromatic comprises the following components in percentage by mass: 40-46% of nanosilicon dioxide hollow spheres, 40-46% of essence, 4-10% of starch, 0.5-3% of superfine silica powder, 2.5-4% of polyvinylpyrrolidone and 1-3% of talcum powder, wherein particle size of each nanosilicon dioxide hollow sphere is 300-500nm. The invention also provides a preparation method of the slow release type solid aromatic. The preparation method of the slow release type solid aromatic comprises the steps of uniformly mixing nanosilicon dioxide hollow spheres, essence and auxiliaries, and carrying out direct compression, so that the slow release type solid aromatic is obtained. The slow release type solid aromatic has the advantages of uniform and slow fragrance release, long scent lasting time, no toxicity, no harm and high essence load capacity and can be widely applied to the fields of daily chemicals, textiles, leathers, coating and the like.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to fragrances, in particular to a slow-release solid fragrance and a preparation method thereof. Background technique [0002] With the progress of social civilization and the improvement of people's quality of life, the fragrant smell is gradually praised by people. Spices and flavors have been widely used in cosmetics, medicine, food, paint, rubber, plastic products, leather and textiles and other fields. However, spices and flavors are mainly volatile small molecular compounds, which are unstable and volatile. They are easily affected by heat and light during use and cause deterioration. Moreover, the currently commonly used flavors are mainly liquid flavors, which is not conducive to transportation. At present, in order to solve the problems of volatile, unstable and short fragrance retention time of essence, microcapsule coating technology is used to improve the volatility of e...
