Abstract

Vulcanized paper raw paper is prepared from the following raw materials: by weight, 94%-97% of cotton fibers, and 3%-6% of glass fibers. A manufacturing method of the vulcanized paper raw paper comprises the following steps of beating, poaching, pulp evening, paper-making and packaging. The vulcanized paper raw paper is high in strength, good in water-absorbing capacity, low in deformability, good in evenness, and good in stiffness. Moreover, the manufacturing process is simple and easy to control, cost is low and period is short.

Description

technical field [0001] The invention relates to a steel paper base paper and a manufacturing process thereof. Background technique [0002] Steel paper base paper is a special paper made from plant fiber by paper machine. The steel paper base paper can be made into steel paper after layer-by-layer stacking and gelation reaction. Steel paper is as hard as steel and as light as paper. It has excellent electrical insulation and is widely used as an insulating material in the electrical industry, textile industry, transportation and other industries. [0003] Further improving the strength and other properties of finished steel paper has always been the goal pursued by the industry. At present, an effective method is to prepare glass fiber-steel paper composite materials, and use the advantages of high strength and good toughness of glass fiber to improve the strength performance of steel paper. For example, a high-strength product is made by wrapping a glass fiber layer on t...
