Antibacterial-effect-enhanced environment-friendly degradable waterproof paper under synergic actions of wood vinegar and lanthanum-zinc white carbon black

Abstract

The invention discloses an antibacterial-effect-enhanced environment-friendly degradable waterproof paper under synergic actions of wood vinegar and lanthanum-zinc white carbon black. The waterproof paper is prepared from the following raw materials in parts by weight: 38-40 parts of bleached softwood pulp, 60-62 parts of cotton pulp, 1.5-1.6 parts of PAE (polyarylether) resin, 1.5-1.6 parts of polyacrylamide, 0.2-0.23 part of alkyl ketene dimer, a right amount of distilled water, 6-7 parts of calcium carbonate, 4.2-4.5 parts of condensed whey protein, 1.8-1.9 parts of konjak glucomannan, 4-4.5 parts of beeswax, 0.1-0.12 part of glycerol, 0.08-0.1 part of Tween 80, 6-7 parts of wood vinegar, 12-13 parts of water glass, 2-3 parts of sodium bicarbonate, 2--2.5 parts of lanthanum nitrate and 1.5-2 parts of zinc sulfate. The product has the advantages of excellent waterproofness, favorable tensile strength and superhigh bactericidal effect, can be widely used for packaging in the fields of industry, food and the like, and is firm and durable.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to an environment-friendly and degradable waterproof paper in which wood vinegar cooperates with lanthanum zinc white carbon black to enhance the antibacterial effect. 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.

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
