Embodiment 1

[0028] 1. Fiber extraction

[0029] Cut sugarcane bark into small sections about 70 mm in length and wash them with clean water.

[0030] Take an appropriate amount of sugarcane peel and add it to clean water, the bath ratio is 1:50, put it in a water bath and boil for 1 hour, replace with new clean water and boil for another 2 hours, then change the water and boil for 1 hour. Take out the sugarcane skin and wash it, put it in a 55°C oven and dry it for later use.

[0031] Take the cleaned and dried sugarcane bark for fiber extraction according to the following process:

[0032] Take 30g of sugarcane skin, put it into 600ml of hydrochloric acid and formic acid mixed solution, the solution contains 15ml of hydrochloric acid with a mass concentration of 36-38%, and 60ml of formic acid with a mass concentration of 88%, stir at 80°C for 60min; take out the solid Wash it with water, put it into 600ml of NaOH solution with a mass concentration of 10%, and stir it at 75°C for 120 m...

Abstract

The invention discloses a sweetcane bark fiber composite and a preparation method thereof. The preparation method comprises the following steps: extracting short fibers from sweetcane barks, adding a certain amount of sweetcane bark short fibers at the beginning of monomer synthesis according to the free radical polymerization mechanism, decomposing initiator molecules into primary free radicals under the condition of heating firstly, then generating a monomer free radical through reaction of the primary free radical and a monomer to further achieve the chain growth, obtaining mixture of sweetcane bark fibers and high molecular polymers after the reaction of the monomer is over, pouring the mixture after being cooled down into a die, drying the mixture at a room temperature to make into a film, and preparing the sweetcane bark fiber composite finally. The sweetcane bark fiber composite is good in formability and uniform in fiber distribution, has excellent hydroscopic property and ventilation property, can be used as base materials of artificial leather, and is used for making clothing, shoes, hats and the like.

Description

technical field [0001] The invention relates to a fiber composite material and a preparation method thereof, in particular to a fiber composite material with a high molecular polymer as a base material and plant fibers as a reinforcing material and a preparation method thereof. Background technique [0002] Fiber composite material is a kind of composite material with fiber as reinforcing material and resin or cement as matrix. Traditional fiber-reinforced composite materials mainly include chemical fibers such as polypropylene fiber, glass fiber, aramid fiber or carbon fiber, which generally have problems such as large energy consumption, high cost, and easy pollution of the environment. Due to the increasing shortage of petrochemical resources, people are constantly looking for new energy and new materials to replace coal and petrochemical products, so as to alleviate or solve the energy and resource crisis. The use of bio-renewable resources to develop environmentally fr...
