Abstract

The invention relates to flavor celluloses and an injection molding method. The flavor celluloses comprise the following raw materials: 60-90 parts of celluloses, 20-30 parts of plasticizer, 0-3 parts of pigment powder and 0.01-0.1 part of flavoring agent, wherein the plasticizer added to the celluloses is conductive to the transfer of the flavoring agent in the celluloses, so that the durability of flavor can be remarkably enhanced without the addition of other compatilizers. The prepared flavor celluloses have high flavor strength and strong flavor durability; the problem of short time of duration of the flavor of conventional celluloses is solved; multicolor cellulose boards manufactured by the flavor celluloses have high elasticity, good air permeability, no electrostatic adherence, no toxicity, very good liquid permeability, good adsorptivity and wide application range, is anallergic after being in contact with skin for a long term, can be dry-cleaned or washed with water and can be manufactured into multiple products such as tool handles and hair pins. The injection molding method of the flavor celluloses 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 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...
