Problems solved by technology

[0004] So far, reed raw materials are mainly used to make paper or let them fend for themselves or even burn them, so that the reeds cannot be fully utilized. At the same time, the environmental pollution caused by incineration will directly affect the ecological environment.

Embodiment 1

[0017] (1) Select healthy reed stalks without insect eyes, and classify reed stalks in different diameter ranges.

[0018] (2) To prepare a modifier, take 30% hydrogen peroxide and use deionized water to prepare solution A with a concentration of 1%, and place it in an inverted test tube for use.

[0019] (3) In step 2, the cut reed stalks with equivalent diameters are put into the test tube containing solution A, and the modifier should be submerged in the reed stalks. In order to prevent the reed stalks from floating on the liquid surface and causing uneven impregnation, seal the container mouth with plastic wrap to avoid the reed stalks from floating out of the test tube during heating and immersion. Put the test tube soaked in the reed stalks into a water bath, and soak at a constant temperature of 80-90°C for 1 hour. After the impregnation is complete, take out the reed stalks and put them in a ziplock bag, and keep them sealed.

Embodiment 2

[0022] (1) Select healthy reed stalks without insect eyes, and classify reed stalks in different diameter ranges.

[0023] (2)) To prepare a modifier, take 30% hydrogen peroxide and use deionized water to prepare solution B with a concentration of 2%, and place it in an inverted test tube for use.

[0024] (3) In step 2, the cut reed stalks with equivalent diameters are put into the test tube containing solution B, and the modifier should be submerged in the reed stalks. In order to prevent the reed stalks from floating on the liquid surface and causing uneven impregnation, seal the container mouth with plastic wrap to avoid the reed stalks from floating out of the test tube during heating and immersion. Put the test tube soaked in the reed stalks into a water bath, and soak at a constant temperature of 80-90°C for 2 hours. After the impregnation is complete, take out the reed stalks and put them in a ziplock bag, and keep them sealed.

Embodiment 3

[0027] (1) Select healthy reed stalks without insect eyes, and classify reed stalks in different diameter ranges.

[0028] (2)) To prepare a modifier, take 30% hydrogen peroxide and prepare a solution C with a concentration of 3% with deionized water, and place it in an inverted test tube for use.

[0029] (3) In step 2, the cut reed stalks with equivalent diameters are put into the test tube containing the solution C, and the modifier should be submerged in the reed stalks. In order to prevent the reed stalks from floating on the liquid surface and causing uneven impregnation, seal the container mouth with plastic wrap to avoid the reed stalks from floating out of the test tube during heating and immersion. Put the test tube soaked in the reed stalks into a water bath, and soak for 3 hours at a constant temperature of 80-90°C. After the impregnation is complete, take out the reed stalks and put them in a ziplock bag, and keep them sealed. It is measured that its density inc...

Abstract

The invention provides a method of toughening and modifying a phragmites communis raw material through hydrogen peroxide. According to the method, the phragmites communis raw material is used as a carrier, 30% hydrogen peroxide is prepared into a modification liquid with concentration of 1-3% by using deionized water; phragmites communis stalk is toughened and modified in a water-bath pot througha constant temperature impregnation manner, wherein treatment temperature is 80-90 DEG C, and time for constant temperature impregnation is 1-3 hours. Results show that density of the phragmites communis stalk modified by hydrogen peroxide is increased by 110-128% according to a bamboo density test method in GB / T 15780-1995 Bamboo Physical and Mechanical Property; calculation of elasticity modulusE of the stalk through a three point bending method shows that the strength is increased by 140-160%, so that the modification effect is good; and the processed phragmites communis is more likely tobend, and can recover completely after bending, thereby being used for production of phragmites communis knitted products.

Description

technical field [0001] The invention relates to a method for toughening and modifying reed raw materials with hydrogen peroxide, and belongs to the technical field of home decoration, preparation and modification of manufacturing materials. Background technique [0002] Our country is rich in reed resources and widely distributed, and there are reed fields or wild reeds in all provinces and cities. Phragmites reed has strong ecological environment function and socioeconomic value, and its strong reproductive ability makes it the main flora of wetland flora. At present, reed is mainly used for papermaking. Because of its rich fiber content and tough stems, it can be used as a substitute for wood, so it has the title of "Second Forest". [0003] The fiber aspect ratio (the ratio of fiber length to fiber width) of reed is higher than that of wheat straw, straw, corn stalk and larch, which makes reed have better physical and mechanical properties. Reed has less non-fibrous cel...
