Abstract

The invention discloses a high-transparency cellulose acetate material and a preparation method thereof. The high-transparency cellulose acetate material comprises the following raw materials by weight: 100 parts of cellulose acetate, 17-25 parts of a plasticizer, 0.1-2 parts of a cross-linking agent, and 0.1-2 parts of other auxiliary agents. The cross-linking agent is selected from isocyanate, dianhydride or peroxide; and the melting point of the cross-linking agent is not higher than 120 DEG C. The preparation process comprises the following steps of uniformly blending all the raw materials, performing heating treatment to perform melting pre-crosslinking modification, and then performing extrusion, granulation and drying to obtain the high-transparency cellulose acetate material. According to the cellulose acetate material prepared by adopting the raw materials and the process, the use amount of a plasticizer is remarkably reduced, and the risk of precipitation is reduced; and the prepared cellulose acetate material has the advantages of high light transmittance, low haze, simple and convenient process flow, short time consumption and high production efficiency, and is suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the field of cellulose acetate materials, and in particular relates to a high-transparency cellulose acetate material and a preparation method thereof. Background technique [0002] Cellulose acetate (CA) is a cellulose derivative obtained by acetylation of cellulose, and it is also the earliest commercialized cellulose derivative. The performance of cellulose acetate depends on the degree of acetylation of the hydroxyl group in the production process. It has the characteristics of good toughness, good gloss, high mechanical strength, high transparency, stable to light, and non-flammable. At present, cellulose acetate is widely used in cigarette filters, textile fibers, medical materials, separation membranes and other fields. [0003] At present, the methods for preparing cellulose acetate transparent products or improving the transparency of cellulose acetate products mainly include: 1, solvent method, after utilizing aceton...
