Problems solved by technology

This kind of porous oil-absorbing film made of synthetic materials has good oil-absorbing effect, soft touch, flexibility and not easy to break, and retains the necessary moisture for the skin while absorbing oil. On the other hand, due to the nature of the material itself, once it touches the skin during use, it will stick to the skin when it is pressed to remove the skin

Abstract

The invention belongs to the technical field of preparation of specialty paper in the paper-making industry and discloses a plant fiber and PHA (polyhydroxyalkanoate) composite oil-absorbing sheet and a preparation method thereof. The preparation method comprises steps as follows: (1) water is added to plant fibers for defibering and dispersion, the mass concentration of the plant fibers is controlled to range from 1% to 3%, and a defibered plant fiber suspension is obtained; (2) an aid, filler and PHA are sequentially added to the defibered plant fiber suspension and evenly mixed, paper is made with pulp and dried, and the plant fiber and PHA composite oil-absorbing sheet is obtained. The biocompatible and environment-friendly PHA is composited with the natural plant fibers, the cost is saved, and the obtained oil-absorbing sheet has good effects of oil absorption, water absorption avoidance, softness and degradability and has the bright application prospect.

Description

technical field [0001] The invention belongs to the technical field of special paper preparation in the papermaking industry, and in particular relates to a plant fiber and PHA composite oil-absorbing paper and a preparation method thereof. Background technique [0002] Facial oil-absorbing paper was first developed in Japan, and it is intended to wipe off excess oil on people's faces, so as to keep the face fresh. While the oil-absorbing paper wipes off excess oil on the face, it can also prevent the clogging of facial pores and prevent the formation of acne and pimples. Therefore, once it is listed, it will be favored by consumers. Commercially available oil-absorbing papers are mainly divided into two categories according to their materials. One is the traditional oil-absorbing paper based on natural plant fibers; the second is an oil-absorbing film based on synthetic materials. [0003] Oil-absorbing paper made of pure plant fibers, such as: cotton, hemp, virgin wood ...
