Abstract

The invention relates to a flame-retardant insulation vulcanized fiber board and a manufacturing technique thereof. On the basis of paper making technology, plant fibers are compounded with many flame retardants, and a production technique combining in-pulp addition and surface treatment is adopted to endow the vulcanized fiber paper with high efficiency, environmental protection and enduring flame retardancy. Meanwhile, the vulcanized fiber board has favorable machining properties (pressure resistance, impact resistance, cutting resistance, scratching resistance, no stratification or blowout under pressure, and the like), and favorable electric insulation properties. The flame-retardant insulation vulcanized fiber board is an excellent environment-friendly special-structure multifunctional material. The production technique comprises the following steps: adding flame retardants in the pulp, carrying primary molding, vacuum dehydration and high-temperature hot-press drying, and impregnating the flame retardants on the surface. The invention has the advantages of lower production cost, simple production technique, easy control, low energy consumption and less water and power consumption, can not produce secondary pollution on the environment, and can implement clean production.

Description

technical field [0001] The invention relates to a flame-retardant insulating steel cardboard, and also relates to a manufacturing method of the flame-retardant insulating steel cardboard. Background technique [0002] In the context of the rapid and steady development of my country's economy, the automobile industry, household appliances, electronic instruments, communications, electroacoustics and other industries are also developing rapidly, and the requirements for processing materials are also increasing rapidly. For example, in the electroacoustic industry such as home audio , home appliance industry such as electric fans, vacuum cleaners, switches, electric tools and other products, due to the strong market demand, many foreign companies have continued to inject capital, and the output has increased rapidly. increase, and the requirements for product quality have also been continuously improved. Insulation moldings such as gaskets and other insulating materials that were...
