Wear-resistant and oil stain-proof book cover packing paper

Abstract

The invention mainly relates to the technical field of packaging material processing, and discloses a wear-resistant and oil stain-proof book cover packing paper. The wear-resistant and oil stain-proof book cover packing paper comprises an outer protective layer and an inner folded layer; the protective layer comprises, by weight, 28-30 parts of natural latex, 17-19 parts of an epoxy resin modified styrene-acrylic emulsion, 3.2-3.4 parts of nanometer titanium dioxide, 2.1-2.3 parts of nano-alumina and 0.5-0.7 part of negative ion powder; and the folded layer comprises, by weight, 41-43 parts of paper fibers, 17-19 parts of cotton fibers, 14-16 parts of bamboo fibers and 6-8 parts of activated carbon fibers. The book cover packing paper has the advantages of high strength, good wear resistance, easiness in folding, softness, comfortableness, avoiding of scratches of corners to skins, good oil-proof and waterproof property, avoiding of oil and water from contaminating the packing paper and then penetrating books, and good book protection effect; and the book cover packing paper is composed of the outer protective layer and the inner folded layer, and the protective layer can preventthe oil and water from penetrating in order to improve the wear resistance of the book cover packing paper.

Description

technical field [0001] The invention mainly relates to the technical field of packaging material processing, in particular to a wear-resistant and oil-proof book cover paper. Background technique [0002] Wrapping the book cover is a common phenomenon in the stage of primary and middle school students. Primary and middle school students cannot protect the books well, so they pack a layer of protective leather on the cover of the book to protect the books from damage.

[0002] Wrapping the book cover is a common phenomenon in the stage of primary and middle school students. Primary and middle school students cannot protect the books well, so they pack a layer of protective leather on the cover of the book to protect the books from damage. In order to meet the requirements of primary and middle school students, the current market There are many kinds of book covers on the Internet, generally made of paper and plastic. The paper book covers are bright in color and soft to the touch, but after a period of use, the edge folds will be worn out, and the paper Book wrapping paper cannot prevent oil stains, and oil stains will quickly penetrate into the book, lacking protective effect, so plastic book wrapping paper came into being, but the plastic book wrapping paper sold in the market now feels hard. It is difficult to fold, so what is sold are all formed book covers. Elementary and middle school students do not need to fold them, they can just put them on the cover of the book. Detachment, and the plastic material is relatively hard, so the corners of the book cover are easy to scratch the skin, and the edge is also easy to wear due to repeated use, so the current book cover paper on the market generally wears out in half a semester Phenomenon, poor durability

[0003] The existing patent document CN 107805364 A provides an oil-stain-resistant packaging bag and its preparation method, specifically disclosing that the composition of the packaging bag is: 100-120 parts by weight of polytetrafluoroethylene, 20 parts by weight of polyethylene terephthalate ~40 parts by weight, 2~4 parts by weight of glycerin, 10~15 parts by weight of luminous powder, 10~20 parts by weight of microprisms, 2~4 parts by weight of stabilizer, 2~4 parts by weight of plasticizer, 10~20 parts by weight of calcium carbonate parts by weight, 4-6 parts by weight of acrylic resin binder, and 2-4 parts by weight of essence, the obtained packaging bag has a good oil-proof effect, but the material is light and thin, it is difficult to fold and shape, and the wear-resistant packaging bag Poor, not suitable for book wrapping paper
