A novel pulp composition having oil resistance and / or water resistance is provided by a pulp composition comprising a liquid-repellent compound and a pulp substrate, wherein the liquid-repellent compound is a compound having a monovalent hydrocarbon group having 6 or more and 40 or less carbon atoms and optionally having a substituent, and is not a fatty acid ester having a glycoside bond, and the pulp substrate comprises bagasse pulp.

The invention discloses safe fully-degradable kraft paper and a preparation method thereof, and relates to the technical field of kraft paper processing. Comprising a base material layer which is formed by mixing 30-40% of bagasse pulp, 20-30% of wheat straw pulp, 25-35% of softwood pulp and 5-10% of bamboo pulp. The bagasse pulp, the wheat straw pulp and other agricultural wastes are compounded with the bamboo pulp to replace part of softwood pulp as the raw material of the base material layer, so that the raw material source is wider and environment-friendly, the dependence on wood resources is reduced, and meanwhile, all components are natural degradable components, so that the overall degradability of the material is improved, and the cost is reduced. The micro gravure coating of the functional coating and the design of the directional barrier layer are combined with the synergistic effect of all the components, so that the degradable kraft paper has comprehensive functions of water resistance, antibacterial property, barrier property and the like while the degradability is ensured, the application scene of the kraft paper is expanded, and the fiber of the base material layer is subjected to microwave-assisted alkali treatment and enzymolysis synergistic pretreatment, so that the comprehensive performance of the kraft paper is improved. The fiber surface activity is improved, the binding force between the fibers is enhanced, and the mechanical strength and formability of the base material layer are effectively improved.

The invention discloses a preparation process of a degradable plant fiber food packaging material, and relates to the technical field of preparation processes of food packaging materials, the technical scheme is that the preparation process comprises the following specific steps: S1, layered pulping: respectively preparing a core layer fiber suspension and a surface layer fiber suspension; the core layer fiber suspension is prepared by taking bamboo pulp, wood pulp and bagasse pulp as raw materials, grinding and pulping, adding a fiber modifier, a reinforcing agent and a compound water-resistant and oil-resistant agent, and diluting; the surface layer fiber suspension is prepared by taking superfine bamboo pulp fibers and konjac glucomannan fibers as raw materials through the steps of accurate grinding, pulping, fiber surface grafting modification, adding of a compound water-resistant and oil-resistant agent and dilution. The meal box has the beneficial effects that the binding force between fibers is improved, the breakage resistance of the meal box is remarkably enhanced, and by designing a surface layer-core layer-surface layer composite structure and adopting a gradient filter pressing process, the fibers between the layers are tightly interwoven, and the layers are not easy to separate.

The present invention is a pulp composition containing a liquid-repellent compound and a pulp base material, the liquid-repellent compound being a compound containing a monovalent hydrocarbon group having 6 or more and 40 or less carbon atoms which can have a substituent, and not being a fatty acid ester having a glycoside bond, and the pulp base material containing bagasse pulp. With the pulp composition, a novel pulp composition having oil resistance and / or water resistance can be provided.

The invention relates to the technical field of functional packaging materials, in particular to degradable oil-proof paper and a preparation method thereof. The method comprises the following steps: 1) mixing nanocellulose, bagasse pulp and modified starch, and carrying out wet papermaking to form a porous substrate layer; 2) spraying a sodium alginate-chitosan composite solution on the surface of the substrate layer to form a hydrophilic barrier layer; and (3) blending anthocyanin microcapsules, zein and hydrophobic modified nano silicon dioxide into a coating material, and coating the surface of the barrier layer with the coating material to form an oil-proof layer, so as to prepare the degradable oil-proof paper. A low-cost and high-performance bio-based raw material foundation is provided through material combination, and construction and function implementation of a gradient structure are supported; according to the structural design, accurate balance of oil-proof, breathable and moisture-proof performance is achieved through a multi-layer framework; the process guarantees efficient manufacturing of a complex structure and complete maintenance of microcapsule functions; and the material is endowed with environmental response and self-monitoring capability.

This utility model discloses a high-efficiency mixing reactor for bleaching bagasse pulp, including a mixing reaction tank, a bagasse pulp preparation tank, and a chlorine dioxide preparation tank. The mixing reaction tank has bagasse pulp inlets and chlorine dioxide inlets on its top two sides, respectively, and a discharge outlet at its bottom. The bottoms of the bagasse pulp preparation tank and the chlorine dioxide preparation tank are higher than the top of the mixing reaction tank, and their bottom outlets are connected to the bagasse pulp inlets and chlorine dioxide inlets respectively via discharge pipes. The bagasse pulp preparation tank contains a float and a level switch, and the chlorine dioxide preparation tank contains a float and a level switch. This utility model, through the floats and level switches in the bagasse pulp preparation tank and the chlorine dioxide preparation tank, can control the submersible pump to disconnect, ensuring a precise ratio of bagasse pulp and chlorine dioxide drawn into the tanks, while also saving labor costs and improving mixing reaction efficiency.
