Abstract

The invention discloses a burst-resistant brown paper and a making method thereof. The burst-resistant brown paper is produced from, by weight, 50-70 parts of coniferous bark, 40-60 parts of broadleaf tree bark, 30-50 parts of waste paper, 10-20 parts of cotton fibers, 15-30 parts of wingceltis bark, 10-15 parts of bamboo, 18-26 parts of bagasse, 8-15 parts of wool, 20-30 parts of grass, 5-10 parts of talcum powder, 8-15 parts of calcium carbonate, 3-5 parts of titanium dioxide, 4-10 parts of diatomite, 5-8 parts of clay, 1-5 parts of zinc borate and 5-10 parts of aluminum sulfate. The t brown paper produced in the invention has good burst resistance.

Description

technical field [0001] The invention relates to a burst-resistant kraft paper and a preparation method thereof. Background technique [0002] Kraft paper (kraftpaper), used as packaging material. The intensity is high. Usually yellowish brown. Semi-bleached or fully bleached kraft pulp is light brown, cream or white. Quantitative 80 ~ 120g / m2. The fracture length is generally above 6000m. Tear strength, work of rupture and dynamic strength are high. Mostly roll paper, but also flat paper. Using kraft softwood pulp as raw material, after beating, it is made on fourdrinier paper machine. It can be used as cement bag paper, envelope paper, glue-sealing paper, asphalt paper, cable protection paper, insulating paper, etc. [0003] Kraft paper (kraftpaper), used as packaging material. The intensity is high. Usually yellowish brown. Semi-bleached or fully bleached kraft pulp is light brown, cream or white. Quantitative 80 ~ 120g / m2. The fracture length is generally abo...
