Embodiment 1

[0014] The preparation process of the palygorskite high-temperature-resistant mold-resistant cardboard of embodiment 1 comprises the following steps:

[0015] S1: To prepare silver-type zeolite, add 4A zeolite into silver nitrate solution, shake for 4-5 hours, filter the suspension with suction, and dry the obtained solid product to obtain silver-type zeolite;

[0016] S2: fiber beating, put palygorskite fiber and bamboo fiber in corresponding containers respectively, add distilled water to soak for 72h, beating respectively, stop when the beating degree of bamboo fiber is 67SR°, and the beating degree of palygorskite fiber is 23SR° beating;

[0017] S3: Pulp papermaking, mixing palygorskite fiber pulp and bamboo fiber pulp obtained in S2 in proportion to prepare a mixed slurry, adding 1‰ cationic polyacrylamide solution and silver-type zeolite made in S1, cationic polyacrylamide in cationic polyacrylamide solution The added amount is 2% of the composite fiber dry pulp in the...

Abstract

The invention discloses a preparation process of a palygorskite high-temperature-resistant anti-mould paperboard, wherein the preparation process includes three steps of silver zeolite preparation, fiber pulping and pulp papermaking. Palygorskite fiber pulp and bamboo fibers are mixed, silver zeolite and cationic polyacrylamide are added, and high-temperature resistance and antibacterial properties of the substances are synthesized, so the paperboard has high temperature resistance, antibacterial property, stronger paper sheet strength, adsorption performance and the like, and can be used as wallpaper.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a preparation process of palygorskite high-temperature-resistant and mold-resistant cardboard. Background technique [0002] Palygorskite fiber is a non-toxic, harmless, high-temperature resistant, high-adsorption and pulp-forming silicate mineral. It is used to make paper as a substitute for asbestos, and it is planned to solve the serious problem of asbestos harm to human health. . So far, there are many sources of fiber palygorskite. Fiber palygorskite deposits have been found in Fengjie and Gongxian County, Sichuan, Dafang, Zhijin and Nayong, Guizhou. In the prior art, there have been many researches on the use of mineral fiber to make paper, such as non-plant fiber and plant fiber to make paper, sepiolite fiber and other fibers to make high-temperature resistant tissue paper, sepiolite fiber and Coniferous wood fibers are mixed with edible oil filter paper, and the resulting edi...
