Abstract

The invention relates to a scented cellulose and an injection molding method thereof. The scented cellulose comprises the following raw materials: 60-90 parts of cellulose, 20-30 parts of plasticizer, 0-3 parts of pigment powder, 0.01-0.1 part of flavoring agent, The plasticizer added in the cellulose of the present invention helps the migration of the fragrance agent in the cellulose, and can significantly enhance the persistence of the fragrance without adding other compatibilizers, and the prepared fragrance cellulose has high fragrance intensity and strong fragrance Strong 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, and is not allergic to long-term contact with the skin. Very good liquid penetration and excellent adsorption, can be dry-cleaned or washed, can be used to make a variety of products such as tool handles, hairpins, etc., and has a wide range of applications. low cost.

Description

technical field [0001] The invention relates to the technical field of cellulose plates, in particular to a scented cellulose and an injection molding method thereof. 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 appropriate fragrance, i...
