Abstract

The invention discloses a process and method for preparing sheet paper from crop straws. The method comprises the following steps: 1, cutting aired crop straws into crop straw sections, and pulverizing the crop straw sections to obtain a pulverized crop material; 2, putting the crushed crop materials into a stirrer, and then injecting water into the stirrer for pulping until the crushed crop materials are uniformly stirred and mixed; 3, filtering the uniformly stirred slurry through a screen to remove impurities in the slurry, and dispersing the slurry through a disperser to obtain raw slurry;and 4, adding the starch fiber, the fast-growing eucalyptus fiber, the bamboo charcoal powder, the sepiolite powder and the carboxymethyl starch into water, and performing heating to 90 DEG C. The preparation process is simple, the production cost is low, the crop straw can be effectively utilized, the prepared straw board adopts the resorcinol adhesive and has water resistance and weather resistance, the overall performance of the board is improved, and use of people is facilitated.

Description

technical field [0001] The invention relates to the technical field of straw utilization, in particular to a process and method for making sheet paper from crop straws. Background technique [0002] Straw is the general term for the stems and leaves of mature crops. It usually refers to the remaining parts of wheat, rice, corn, potato, rape, cotton, sugarcane and other crops after harvesting seeds. More than half of the photosynthetic products of crops exist in straw. Straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter. It is a multi-purpose renewable biological resource. Straw is also a kind of roughage. It is characterized by high crude fiber content and contains lignin. Lignin Although cellulose cannot be utilized by pigs and chickens, it can be absorbed and utilized by ruminant cattle, sheep and other livestock. [0003] With the rapid development of the wood-based panel industry, the insufficient supply of wood raw materials has incr...
