Abstract
The invention provides a manufacturing method of an environment-friendly corrugated board capable of being rapidly degraded, and relates to the technical field of paper product manufacturing. According to the manufacturing method of the rapidly-degraded environment-friendly corrugated board, a degradation raw material group comprises the following raw materials in parts by weight: 5-15 parts of polyurethane, 2-3 parts of polyvinylamine and 10-15 parts of ammonium chloride, and a flame-retardant raw material group comprises the following raw materials in parts by weight: 2-5 parts of aluminum nitrate, 5-10 parts of ammonium chloride, 20-30 parts of pure water, 10-15 parts of silicon monoxide and 10-20 parts of citric acid. In the stirring process, ammonium chloride is added into the stirring furnace every half an hour, the water solubility of the paperboard is improved through the added polyvinylamine and polyurethane, the degradation and separation speed of silicon contained in the paperboard is increased, and the silicon is dissolved and eliminated through the ammonium chloride; the temperature of the high-temperature stirring tank is increased to 120-130 DEG C, stirring is carried out, the obtained flame-retardant liquid is mixed with paperboard raw materials, the activeness of cellulose contained in the paperboard at the high temperature is reduced, and the flame-retardant capacity is improved.
