Abstract

The invention discloses a straw fiber and bast fiber mixed nonwoven fabric for water-resistant and heat-resistant seamless wallpaper. The straw fiber and bast fiber mixed nonwoven fabric is prepared from the following raw materials in parts by weight: 220-205 parts of straws, 100-104 parts of original hemps, a proper amount of NaOH, a proper amount of water, 0.8-0.85 part of polyvinyl alcohol, 0.5-0.6 part of bamboo charcoal powder, 0.2-0.3 part of trifluoroethyl methacrylate, 0.2-0.3 part of dodecafluoroheptyl methacrylate, 5-6 parts of ethyl acetate, 0.4-0.5 part of 4,4'-diphenylmethane diisocyanate, 0.4-0.5 part of hydroxyl silicon oil, 0.7-0.9 part of a waterborne fluorocarbon emulsion, 0.3-0.4 part of nanometer polytetrafluoroethylene and 0.05-0.1 part of dicumyl peroxide. The nonwoven fabric disclosed by the invention is prepared from 4,4'-diphenylmethane diisocyanate, the hydroxyl silicon oil and the waterborne fluorocarbon emulsion, so that the water resistance, heat resistance and toughness of the nonwoven fabric are improved; and due to the use of the bamboo charcoal powder, the nonwoven fabric has an antibacterial property.

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 water-resistant and heat-resistant 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 ch...
