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 the technical field of cellulose plates, and in particular to a fragrance cellulose and a method for preparing a multi-colour cellulose plate by applying the fragrance cellulose. The fragrance cellulose is composed of the following raw materials in the following parts by weight: 60-100 parts of cellulose, 20-50 parts of a plasticizer, 0-3 parts of pigment powder and 0.01-0.1 parts of a flavouring agent. According to the method disclosed by the invention, the plasticizer added in cellulose is conducive to migratinge the flavouring agent in cellulose, the persistence of fragrance can be remarkably enhanced without the need of adding other compatilizerscompatilizers, the prepared cellulose is high in fragrance intensity and strong in fragrance persistence, and the problem of short fragrance persistence time of the existing cellulose is solved; the prepared multi-colour cellulose plate is high in elasticity, good in air permeability, without free from electrostatic adsorption, non-toxic, non-allergic in case of being contacted with the skin for a long time, great in liquid transmission property, excellent in adsorbability, capable of being dry-cleaned or water-washed, capable of being applied to preparinge various products such as tool handles, hairpins and the like, and wide in application range; and the method for preparing the multi-colour cellulose plate disclosed by the invention is simple in process and low in 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...
