Problems solved by technology

[0003] It is difficult to meet the requirements of written paper due to the different preparation techniques of written paper. In addition, the flame retardant effect of existing written paper is not good. Score: bamboo pulp: 10-30 parts; asparagus grass pulp: 50-80 parts; wood pulp: 5-20 parts; water-soluble polyvinyl alcohol fiber: 5-15 parts; silk: 5-20 parts; agent: 0.01-1 part; waterproofing agent: 0.001-0.5 part; the starch binder includes starch, urea-based resin, sodium bromide, ammonium chloride and water, and the flame retardancy of the written paper prepared in this document is not the best Good, still can be further improved

Abstract

The invention discloses cover paper with a fireproof and flame-retardant function. The cover paper comprises the following raw materials in parts by weight: 34-36 parts of a mixed pulp, 18-22 parts ofpolyvinyl alcohol fiber, 13-17 parts of sea island fiber, 6-10 parts of emulsified paraffin, 1-3 parts of melamine, 8-12 parts of modified clay mineral powder, 6-10 parts of a flame retardant intensifier, 3-5 parts of a waterproof assistant and 12-18 parts of deionized water. The purpose of the invention is to provide the cover paper with the fireproof and flame-retardant function and a preparation method thereof, and the cover paper has a good fireproof and flame-retardant effect, is greatly improved as compared with the prior art, and has a high use value and a good application prospect.

Description

technical field [0001] The invention relates to the technical field of writing paper, in particular to a writing paper with fireproof and flame retardant functions and a preparation method thereof. Background technique [0002] Written paper is also called book cover paper, which is the paper used to print the cover of books. Pigments are added to the written paper when making paper, and it has gray, blue, beige and other colors. Originally, all paper suitable for calligraphy and painting is called written paper. However, due to the prevalence of imitation rice paper , as the difference can be seen, the title of written paper that appears, the difference between written paper and Xuan paper lies in the raw materials and manufacturing process. [0003] It is difficult to meet the requirements of written paper due to the different preparation techniques of written paper. In addition, the flame retardant effect of existing written paper is not good. Score: bamboo pulp: 10-30 p...
