Abstract

The invention discloses a fragrance adsorption and slow release mobile phone shell and a production method thereof. The fragrance adsorption and slow release mobile phone shell comprises an inner layer, two sides of the inner layer are provided with matched outer layers, and the length of the inner layer is the same as that of the outer layers. The lengths of the inner layer and the outer layers are 80-120mm; and each outer layer is made of xanthan gum, and the inner layer is made of starch-beta cyclodextrin composite microspheres. The invention further discloses a production method of the fragrance adsorption and slow release mobile phone shell. According to the invention, the starch-beta cyclodextrin composite microspheres serve as the inner layer, the outer layers are coated with the xanthan gum to produce the mobile phone shell, the mobile phone shell has the fragrance adsorption and slow release functions, and the problems that an existing mobile phone shell does not have the fragrance slow release function, and the fragrance release time cannot be prolonged are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of mobile phone cases, and in particular relates to a mobile phone case for aroma absorption and slow release and a preparation method thereof. Background technique [0002] As of June 2020, the number of netizens in my country has reached 940 million, and the Internet penetration rate is 67.0%. The Internet has become an indispensable part. As the most convenient carrier of the Internet, smart phones have become a necessity for everyone in today's society. The mobile phone case is a kind of decoration for people to protect the mobile phone and show their individuality. Nowadays, there are many kinds of mobile phone cases, and there are several kinds of materials for making mobile phones, from the previous plastic, mirror, and metal to the current Kevlar, acrylic, Liquid silicone, etc. These materials have their own advantages, but all of them are products with a single function. [0003] According to the ...
