Abstract

The invention belongs to the technical field of celluloid sheet processing, and particularly relates to a celluloid sheet. The celluloid sheet is prepared from 58-72% by weight of nitrocotton, 15-21%by weight of camphor powder, 0.1-0.3% by weight of glacial acetic acid, 0.1-0.3% by weight of sodium carboxymethyl cellulose, 0.1-0.3% by weight of pigment powder, 2.6-3.4% by weight of zinc oxide powder, 1.1-2.3% by weight of acrylate high glue powder KM355P, 8.2-13.6% by weight of a flame retardant, 0.1-1.5% by weight of an aid and the balance of a solvent. According to the invention, the mechanical properties such as toughness, strength and the like of celluloid are improved, the service life of celluloid products is prolonged, the stability of the products is enhanced, especially, the fatal defect that celluloid is inflammable is overcome to a greater extent, and the products have multiple effects and have higher industrial popularization value.

Description

technical field [0001] The invention belongs to the technical field of celluloid sheet processing, and in particular relates to a celluloid sheet and a manufacturing process thereof. Background technique [0002] Celluloid sheets are the material used to make decorative panels for musical instruments. At present, all manufacturers of musical instrument decorative boards use pure color chips such as red or black as materials for making musical instrument decorative boards. Pure-colored tablets are made of nitrocellulose as the main material, acetone and ethanol as the solvent, zinc oxide as the filler, camphor powder as the plasticizer and ethyl acetate as the toughening agent. After the processes of rubber calendering, hot pressing, planing, drying and pressing, it is made into celluloid sheets for musical instrument decorative boards. It mainly has the following deficiencies: [0003] (1) If it is used for a long time, the color is easy to change; [0004] (2) Ethyl ace...
