Problems solved by technology

[0002] As we all know, paper is made of plant fibers and can be folded arbitrarily for writing. Paper is the carrier of writing and printing, and can also be used for packaging or hygiene and other purposes, such as printing paper, carbon paper, toilet paper and facial paper, etc. , Nowadays, the scope of application of paper has been imagined by people in Chaohu, and all walks of life are inseparable from the application of paper, so the performance requirements of paper are becoming more and more stringent, especially in the packaging and catering industries, the waterproof performance of paper There are strict requirements, but the waterproof performance of existing paper is mostly unsatisfactory

Abstract

The invention relates to environment-friendly paper with good waterproof effect, belonging to the technical field of papermaking. According to the invention, a mixture of starch, diluted sulfuric acid, salicylic acid, rosin, nanometer palladium, a silicon latex and magnesium oxide is prefabricated; meanwhile, the mixture is sprayed onto the outer surface of paper; the mixture composed of the starch, the diluted sulfuric acid, the salicylic acid, the rosin, the nanometer palladium, the silicon latex and the magnesium oxide has high waterproof performance and is non-toxic and odorless, so obtained finished paper has high waterproof performance and can be securely applied in the catering industry; meanwhile, after the mixture of the starch, the diluted sulfuric acid, the salicylic acid, the rosin, the nanometer palladium, the silicon latex and the magnesium oxide is sprayed onto the outer surface of the paper and undergoes secondary calendering, no influence is generated on the writing handfeel of the paper, and the paper can be still applied in the field of office work; and through addition of butylparaben and citric acid, the anti-corrosion performance of the paper is increased, andthe storage life of the environment-friendly paper provided by the invention is improved.

Description

Technical field [0001] The invention belongs to the technical field of papermaking, and particularly relates to an environmentally friendly paper with good waterproof effect. Background technique [0002] As we all know, paper is made of plant fibers and can be folded arbitrarily for writing. Paper is a carrier for writing and printing. It can also be used for packaging or sanitation and other purposes, such as printing paper, carbon paper, toilet paper and facial tissue, etc. Nowadays, the scope of application of paper has been imagined by people in Chaohu, and all walks of life are inseparable from the application of paper, so the performance requirements of paper are becoming more and more demanding, especially in the packaging and catering industries, the waterproof performance of paper There are strict requirements, but the waterproof performance of existing papers is mostly unsatisfactory. Summary of the invention [0003] Aiming at the problems in the background, the purpo...
