High-efficiency waterproof kraft paper and preparation method thereof

Abstract

The invention discloses high-efficiency waterproof kraft paper and a preparation method thereof. The high-efficiency waterproof kraft paper comprises a body paper base layer and a coating layer covering the body paper base layer; the body paper base layer comprises the following components according to a weight ratio: fir, pine, phoebe zhennan, poplar, wood dust, a wooden furniture leftover material, sugarcane stems, Chinese banana stems, animal hair, a paper-making additive and a filler; the coating layer is a waterproof coating layer; the coating layer is prepared from cationic starch, a perfluorinated alkyl compound, acrylic resin, polyving akohol, 2,2'-azobis[2-methylpropionamidine] dihydrochloride, functional monomer, animal glue and the balance of distilled water. The high-efficiencywaterproof kraft paper is prepared and has the effects of convenience for use, low price and good waterproof effect.

Description

technical field [0001] The invention relates to a high-efficiency waterproof kraft paper and a preparation method thereof. Background technique [0002] Kraft paper is a common wrapping paper material. Its strength is higher than that of ordinary wrapping paper. In the paper state, there are two shapes of roll and flat sheet, but it can also be used in envelope paper, glued paper packaging, asphalt paper and other places. [0003] Kraft paper can be divided into packaging kraft paper, high-efficiency waterproof kraft paper, moisture-proof kraft paper, anti-rust kraft paper, pattern-making kraft paper, process kraft paper, insulating kraft board, kraft stickers, etc. kraft paper plays the most important role in the use process. It is tensile and quite good waterproof performance. The waterproof performance on the market is mainly obtained by various additives, but the existing additives include some coagulants, defoamers, flocculants, fillers and other materials that do not ...

Problems solved by technology

[0003] Kraft paper can be divided into packaging kraft paper, high-efficiency waterproof kraft paper, moisture-proof kraft paper, anti-rust kraft paper, pattern-making kraft paper, process kraft paper, insulating kraft board, kraft stickers, etc. kraft paper plays the most important role in the use process. It is tensile and quite good waterproof performance. The waterproof performance on the market is mainly obtained by various additives, but the existing additives include some coagulants, defoamers, flocculants, fillers and other materials that do not have waterproof performance. Moreover, existing processing plants often focus on profit, and they are all cheap and how to produce. The effects obtained by adding different additives are completely different. Patent No. CN201510952750.3 discloses a production process for kraft paper. The beating degree and wet weight of trees are adjusted, and the beating degree of trees is not very related to the waterproof effect. It is mainly changed by additives, but there is no kraft paper with better water resistance on the market.
