Abstract

The invention belongs to the technical field of vulcanized paper and particularly discloses high-tinting-strength green vulcanized paper for abrasive discs. The high-tinting-strength green vulcanized paper is prepared from, by weight, 100-120 parts of cotton fibers, 40-70 parts of wood pulp cellulose, 4-12 parts of an inorganic composite pigment, 0.8-1.2 parts of a dispersing agent, 2-4 parts of water-soluble chitosan, 2-6 parts of an insulation reinforcing agent, 3-7 parts of a heatproof reinforcing agent and 1-3 parts of a setting agent. The inorganic composite pigment is prepared from glauconite, green serpentine and a cobalt green pigment, a particle size range of glauconite and green serpentine is 0.1-1nm, and glauconite and green serpentine are calcined for 2-3h at 500-600DEG C before use. The green vulcanized paper for the abrasive discs is high in tinting strength, less prone to fading, moisture absorption and deformation, great in heatproof performance, insulating, flame retardant and long in service life, and prepared abrasive discs are high in processing precision due to great surface fineness of the green vulcanized paper.

Description

Technical field [0001] The invention belongs to the technical field of steel paper, and in particular relates to a green grinding sheet steel paper with strong tinting power. Background technique [0002] Steel paper, also known as hardened paper, is a kind of processing paper with high hardness. It is made by expanding and gelling raw fibers with zinc chloride solution. It has high wear resistance, corrosion resistance, heat resistance and insulation properties. As well as mechanical processing performance, the processed products are durable and light in weight and beautiful. They can be made into red, green or gray by adding pigments for cutting, drilling, grinding and other mechanical processing. However, the steel paper has the following problems in the use: firstly, organic dyes are added to the existing steel paper base paper, and the low color fastness causes the steel paper to fade and fade; secondly, the steel paper has general heat resistance, and the high temperature g...
