Embodiment Construction

[0011] This product is made of recycled paper pulp, wood pulp board, water repellant, and oil repellent, with one side smooth and one side with a coarser texture. The smooth surface of paper products is covered with PE film. The waterproofing agent generally uses cationic neutral paper glue such as UNT multifunctional waterproofing agent and HFS-I waterproofing agent; in order to strengthen the waterproofing performance of the product, an oil-proofing agent of dry pulp weight (1-3%) is added to the pulp. The anti-oil agent used is the imported F321 oil-proof agent of France Atofina Company and DuPont Company of the United States and the domestically produced HF-I oil-proof agent. This kind of oil repellent is a copolymer of water-dispersible fluorine-containing acrylate and other non-fluorine monomers, which has extremely low surface tension and excellent waterproof, oil-proof and stain-proof properties.

Abstract

The invention relates to section paper angle protector, paper pad and relative producing method, which provides a packing material used to pack section materials. Wherein, the paper angle protector and the paper pad are made from recycled paper (vellum or newspaper or/and yellow plate), wooden slurry plate, waterproof agent, and oil-proof agent. Said producing method comprises: processing the recycled paper and wooden slurry plate, with dipping, breaking, and adding waterproof agent and oil-proof agent to prepare slurry, and via molding and vacuum slurry adsorption, to shape; molding it with molding module in high temperature and high pressure; cutting edge to attain final product. The invention uses pulp as raw material, with lower cost. And it adds waterproof agent and oil-proof agent to attain waterproof property, flexibility and better anti-drawing property. The invention can be decomposed and nontoxic. It has lower producing cost and high efficiency, while the product can be used to pack steel, wood, stone and ceramic.

Description

technical field [0001] The invention relates to a packaging material for profile packaging and a production method thereof. Background technique [0002] General industrial paper mold packaging products mostly use the mixed pulp of yellow cardboard and newspaper (or white paper edge). After fixed molding, it requires good compressive strength and cushioning performance, but it does not require flexibility. The requirements are not high. However, the packaging material produced by the present invention needs to be bent and folded at 90°C, and the top is perforated, so that the packaging steel belt can pass through, and it must be suitable for open-air storage, so the packaging material must be flexible, waterproof, and must have a certain tensile strength strength. In order to meet the flexibility requirements, the fiber of the packaging material should be long, so that the product is not easy to break when it is bent and folded. And the existing "a...
