Embodiment Construction

[0016] A non-woven fabric mixed with straw fiber and hemp fiber for seamless wallpaper, made of the following raw materials in parts by weight (kg): 200 parts by weight of rice straw, 100 parts by weight of raw hemp, appropriate amount of NaOH, appropriate amount of water, 0.73 polyvinyl alcohol, and nanometer aluminum hydroxide 0.2, epoxy lignin 0.2, trifluoroethyl methacrylate 0.2, dodecafluoroheptyl methacrylate 0.2, ethyl acetate 5, polyaniline nanofiber 0.3, nano polytetrafluoroethylene 0.3, isopropyl peroxide Benzene 0.05.

[0017] The preparation method of the straw fiber and hemp fiber mixed non-woven fabric for the seamless wallpaper comprises the following steps:

[0018] (1) Cut the straw into 3cm sections, add water according to the weight ratio of straw: water 1:20, add NaOH according to the weight ratio of straw: NaOH 1:0.6, stir evenly, heat to 89°C, stir and react under heat preservation conditions 1.8h, filter, wash with water until the pH is 7, and dry to ob...

Abstract

The invention discloses a straw fiber-hemp fiber mixed non-woven fabric used for seamless wallpaper. The straw fiber-hemp fiber mixed non-woven fabric is prepared from, by weight, 200 to 205 parts of straw, 100 to 104 parts of raw hemp, an appropriate amount of NaOH, an appropriate amount of water, 0.7 to 0.75 part of polyvinyl alcohol, 0.2 to 0.3 part of nano aluminium hydroxide, 0.2 to 0.3 part of epoxidized lignin, 0.2 to 0.3 part of trifluoroethyl methacrylate, 0.2 to 0.3 part of dodecafluoroheptyl methacrylate, 5 to 6 parts of ethyl acetate, 0.3 to 0.4 part of polyaniline nano fiber, 0.3 to 0.4 part of nano polytetrafluoroethylene, and 0.05 to 0.1 part of dicumyl peroxide. The straw fiber-hemp fiber mixed non-woven fabric is low in moisture regain rate, possesses mildew resistance, is high in toughness and strength; adding of polyaniline nano fiber is capable of improving elasticity, water resistance, and durability of the straw fiber-hemp fiber mixed non-woven fabric; adding of nano aluminium hydroxide and epoxidized lignin is capable of improving heat resistance, flame resistance, and toughness of the straw fiber-hemp fiber mixed non-woven fabric.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric manufacturing, in particular to a non-woven fabric mixed with straw fiber and hemp fiber for seamless wallpaper and a preparation method thereof. Background technique [0002] my country is rich in straw resources, ranking first in the world. Among them, rice straw accounts for 27.5%, corn straw accounts for 36.7%, and wheat straw accounts for 15.2%. The total amount of straw that can be used as energy is 376.1 million tons. At present, a large amount of waste rice stalks still face incineration as the only way to deal with them. Develop new uses of rice straw and solve new problems of rice straw treatment, which can not only reduce environmental pollution and management costs caused by burning rice straw as waste, but also turn waste into treasure, make full use of the value of rice straw resources themselves, and save resources . [0003] Through chemical composition research, rice s...
