Problems solved by technology

[0003] But the compatibility of flavoring agent and cellulose of existing cellulose board material is relatively poor, after using for a period of time, fragrance is completely dissipated, causes the persistence of fragrance to be shorter, and existing cellulose board material color is single in addition, can't satisfy people. requirements

Abstract

The invention relates to a scented cellulose and a method for preparing multi-colored cellulose plates using the scented cellulose. The scented cellulose is composed of the following raw materials: 60-100 parts of cellulose, 20-50 parts of plasticizer, 0-3 parts of pigment powder, Fragrance agent 0.01~0.1 part, the plasticizer that the present invention adds in cellulose helps flavor agent migrate in cellulose, does not need to add other compatibilizer and can significantly strengthen the persistence of fragrance, the fiber that makes The plain fragrance has high strength and strong fragrance persistence, which solves the problem of short duration of the existing cellulose fragrance. The multi-color cellulose sheet has high elasticity, good air permeability, no electrostatic adsorption, non-toxic, long-term and It is not allergic to skin contact, has good liquid penetration and excellent adsorption, can be dry-cleaned or washed, and can be used to make tool handles, hair clips and other products, with a wide range of applications. The multi-color cellulose prepared by the present invention The plate method has simple process and low production cost.

Description

technical field [0001] The invention relates to the technical field of cellulose plates, in particular to a scented cellulose and a method for preparing multi-color plates using the same. Background technique [0002] Cellulose is the oldest and most abundant natural polymer on the earth. It is inexhaustible and the most precious natural renewable resource for human beings. The cellulose sheet made of it has low thermal conductivity and can be produced flexibly. , a variety of visual effects, excellent fluidity, good surface gloss, good electrical insulation, anti-static, self-brightness, high transparency, strong pressure resistance, unique surface vision, has been widely used in tool handles, hair clips, Toys, goggles, helmets, glasses frames, toothbrushes, tableware handles, combs and photo negatives, etc., as people's requirements for cellulose products continue to increase, people add flavoring agents to them, so that the prepared cellulose can Exudes a pleasant or app...
