Cross-linking grafted modified collagen tensile water-proof enhanced degradable paper

Abstract

The invention discloses cross-linking grafted modified collagen tensile water-proof enhanced degradable paper. The cross-linking grafted modified collagen tensile water-proof enhanced degradable paper is prepared from the following raw materials in parts by weight: 38 to 40 parts of bagasse pulp, 60 to 62 parts of hardwood pulp, 8 to 9 parts of nanometer bentonite, 0.2 to 0.25 part of alkyl ketene dimmer, 1.5 to 1.6 parts of PAE resin, an appropriate amount of distilled water, 1.8 to 1.9 parts of gulcomannan, 4.2 to 4.5 parts of concentrated whey protein, 4 to 4.5 parts of beewax, 0.1 to 0.12 part of glycerinum, 0.08 to 0.1 part of Twain 80, 0.12 to 0.14 part of epoxy chloropropane, 2 to 2.3 parts of industrial collagen powder, 0.09 to 0.1 part of sodium persulfate, 1.1 to 1.2 parts of butyl acrylate, an appropriate amount of a sodium hydroxide solution with the concentration of 10% and 1 to 1.2 parts of polyacrylamide. The product prepared in the invention is excellent in waterproof effect, solves the defect that original paper is broken when encountering water, and can be used for packaging; and the product is solid and durable, high in strength, environment-friendly and degradable.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a cross-linked graft modified collagen tensile strength and water-repellent enhanced degradable paper. Background technique [0002] Paper fibers are highly hydrophilic. Generally, after untreated paper is soaked in water, most of the fiber strength will be lost, or even broken directly. In order to meet the needs of people's life and the development of modern industrial technology, the application field of paper is increasing. Waterproof paper is widely used in product packaging, food packaging and other fields. With the increasing awareness of environmental protection, people's demand for environmentally friendly and degradable waterproof paper is becoming stronger and stronger.

AI Technical Summary

Problems solved by technology

In the article, the waterproof base paper is mainly prepared from cellulose. Even if specific additives such as wet strength agent and sizing agent are added, its biodegradability is still outstanding. Under certain conditions, after a certain period of time, the waterproof paper It can still be completely degraded, but its waterproof effect has certain limitations. At present, there are PP waterproof papers on the market. A special process is used to make PP coated on the surface of the paper, so that the paper has good waterproof performance. Since PP is a petrochemical product, It has high stability and is difficult to biodegrade, causing harm to the environment
