Abstract

The invention belongs to the technical field of vulcanized paper and particularly discloses red abrasive disc vulcanized paper with high tinting strength. The red abrasive disc vulcanized paper is prepared from the following components in parts by weight: 100-120 parts of cotton fiber, 50-70 parts of wood pulp fiber, 4-10 parts of an inorganic composite pigment, 0.8-1.6 parts of a dispersing agent, 1-2 parts of water-soluble chitosan, 2-6 parts of an insulating reinforcing agent, 3-7 parts of a heat-resistant reinforcing agent and 1-3 parts of a setting agent; the inorganic composite pigment is prepared from rhodolite, vermilion and cadmium red at the weight part ratio of (0.4-0.8):(0.3-0.5):1; and the particle size ranges of the rhodolite and vermilion are 0.1-1nm. The red abrasive disc vulcanized paper is high in tinting strength, not easy to fade, good in heat resistance, not easy to absorb moisture or deform, insulated, flame-retardant and long in service life, meanwhile, the surface of the red abrasive disc vulcanized paper is good in smoothness and the prepared abrasive disc is good in machining precision.

Description

technical field [0001] The invention belongs to the technical field of steel paper, in particular to a red abrasive steel paper with strong tinting strength. Background technique [0002] Steel paper, also known as hardened paper, is a kind of processed paper with high hardness. It is made by expanding and gelling the raw material fiber with zinc chloride solution. It has high wear resistance, corrosion resistance, heat resistance and insulation performance. And mechanical processing performance, the processed products are durable, light and beautiful, and can be made into red, green or gray by adding pigments, which are used for cutting, drilling, grinding and other mechanical processing. However, there are the following problems in the use of steel paper: firstly, organic dyes are added in the preparation of the existing steel paper base paper, and the color fastness is low, which causes the color of the steel paper to fade and fade; secondly, the heat resistance of the st...
