Abstract

The invention relates to the technical field of cellulose plates, in particular to a scented cellulose and a method for preparing a single-color plate using the scented cellulose. The scented cellulose consists of the following raw materials in parts by weight: 80-120 parts by weight of cellulose acetate, plasticizer 20~40 parts, 0.01~0.1 parts of fragrance agent and 0~1 part of pigment powder. A method for preparing a single-color plate using the above-mentioned scented cellulose, comprising the following steps: A, adding the above-mentioned cellulose acetate and plasticizer in the blender, stirring at room temperature for 18-30 hours at a speed of 60-100 r / min, Obtain the mixture; B, put the above mixture into a twin-screw extruder, melt and extrude it, cool it to 30~40°C, and cut it into pellets to obtain the rubber material; C, put the above rubber material and the above weight parts of flavoring agent and pigment powder into The single-screw extruder is melted and extruded to obtain a single-color plate of flavored cellulose. The scented cellulose monochromatic plate prepared by the invention has strong scent persistence.

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 monochrome 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. As a recyclable material, cellulose has low thermal conductivity, flexible production, various visual effects, excellent fluidity, good surface gloss, good electrical insulation, anti-static, self-brightness, high transparency, compression resistance Strong, unique surface vision, has been widely used in tool handles, hairpins, toys, goggles, helmets, glasses frames, toothbrushes, tableware handles, combs and photo negatives, etc. [0003] Various applications using plastics such as cellulose can be increased if the cellulose can emit a pleasant or appropriate fragrance.
