Embodiment 1

[0015] 200 μL of silane coupling agent methyltrimethoxysilane was added dropwise to 105 g of PDMS emulsion (10% solid content), stirred and mixed evenly to obtain silicone emulsion immersion solution; sisal fibers were soaked in water after washing and drying In the immersion solution, ultrasonically disperse for 5 minutes, after soaking evenly, take out the sisal fiber and remove the excess immersion solution, and then place it at room temperature for curing to obtain the modified sisal fiber.

Embodiment 2

[0017] Add 500 μL of silane coupling agent methyltrimethoxysilane dropwise to 200 g of PDMS emulsion (solid content 10%), stir and mix evenly to obtain silicone emulsion immersion solution; wash and dry sisal fiber soaked in In the immersion solution, ultrasonically disperse for 5 minutes, after soaking evenly, take out the sisal fiber and remove the excess immersion solution, and then place it at room temperature for curing to obtain the modified sisal fiber.

Embodiment 3

[0019] Add 200 μL of silane coupling agent KH-550 dropwise to 105 g of PDMS emulsion (solid content 10%), stir and mix evenly to obtain a silicone emulsion immersion solution; soak the sisal fiber after washing and drying in the immersion solution , ultrasonically dispersed for 5 min, soaked evenly, took out the sisal fiber and removed the excess immersion liquid, and then placed it at room temperature to solidify, that is, the modified sisal fiber was obtained.

Abstract

The invention discloses a method for preparing a waterproof material by modifying surfaces of sisal fibers with water-based organosilicone. The method utilizes sisal fibers as raw materials, and through the simple immersion curing process, surfaces of the sisal fibers form organosilicone hydrophobic layers. The method which produces sisal fibers with high hydrophobicity through hydrophilicity change is a simple and effective sisal fiber surface modification method. The method has the advantages of use of cheap and easy raw materials with wide raw material sources and simple and fast preparation process. The method realizes the synergistic effects of organosilicone and sisal fibers and overcomes the defects of use of the single material. The organosilicone hydrophobic layer coats the sisal fiber surface so that the sisal fibers have hydrophobicity, fiber interface adhesion is improved and sisal fiber application development is broadened.

Description

technical field [0001] The invention belongs to the technical field of sisal fiber modification, and in particular relates to a method for preparing a waterproof material by modifying the surface of sisal fiber with water-based organic silicon. The surface modification method is simple and efficient, which makes the sisal fiber hydrophobic, improves its interfacial adhesion, and can broaden the research and application of the sisal fiber. Background technique [0002] As the most abundant green and environmentally friendly renewable resource on the earth, natural plant fiber has attracted extensive attention in its application and development. Sisal is a perennial natural hard fiber plant with leaves of the genus Agave. As an important natural tropical economic crop, it is widely planted in parts of southern my country. Sisal bundle fiber has hard texture, high strength, low density, high cellulose content, easy surface modification, low price, and is a renewable resource. ...
