| titleOfInvention | A kind of corrugated base paper waterproof and moisture-proof method |
| abstract | The invention provides a water-proof and moisture-proof method for corrugated base paper. In the method, 100% national waste is used as raw material to prepare pulp, and the pulp is improved in the dehydration stage and the forming stage of the wire part respectively to obtain the corrugated base paper after the homogenization treatment; the starch is subjected to gelatinization treatment with biological amylase , get the gelatinized starch, pump the gelatinized starch, aluminum sulfate and defoamer to the surface glue working tank to mix, pump the SAE surface sizing agent to the surface glue working tank to mix, get the mixture, mix the mixture The surface sizing agent and AKD are transported to the sizing machine through the conveying pump to obtain the surface sizing material; the sizing material is subjected to surface sizing treatment on the corrugated base paper under a certain temperature on the sizing machine to obtain the finished product. The method can improve the retention rate of the sizing medicine, greatly reduce the loss of the sizing medicine, reduce the cost, and can improve the water resistance and moisture resistance of the corrugated base paper. |
