Embodiment 1

[0014] (1) Select healthy reed stalks without insect eyes, and classify reed stalks in different diameter ranges.

[0015] (2) To prepare a modifying agent, take 85 parts of polyethylene glycol 200, 5 parts of ethanol, and 10 parts of water to prepare a solvent for modifying reed stalks.

[0016] (3) Put the cut reed section into a test tube, pour the modifying agent solution until the reed straw is submerged. In order to prevent uneven impregnation caused by reeds floating on the liquid surface, seal the test tube mouth with plastic wrap, and use a needle to poke a few holes in the plastic wrap to avoid uneven pressure due to the plastic wrap during negative pressure dipping. Put the test tube into a vacuum box and impregnate under negative pressure for 12 to 36 hours at a pressure of -0.09MPa and a temperature of 40-60°C. After soaking, take it out and put it in a ziplock bag, and keep it sealed for later use.

[0017] The reed stalk modified by this method, with reference...

Abstract

The invention provides a toughening modification processing process of reed straws for reed weaving products. The toughening modification processing process of the reed straws for the reed weaving products comprises the steps that reed raw materials are used as a carrier, and a modifying agent is prepared from the following components by parts: 70-90 parts of polyethylene glycol 200, 5-10 parts ofethyl alcohol and 10-30 parts of water. A vacuum dipping mode is adopted in modification processing, the processing condition is that the pressure is -0.09 MPa, the temperature is 40 DEG C-60 DEG C,and the dipping time is 12-36 hours. The reed straws are taken out and placed into a self-sealing bag after dipping for sealing storage. According to the modified reed straws through the method, referencing a bamboo wood test density method in (GB / T 15780-1995 bamboo wood physical and mechanical property), and the density of the reed straws is tested by increasing 553%; and an elasticity modulus Eof the reed straws is calculated by using a three-point bending method to obtain the intensity of the reed straws increasing by 600%, and the modification effect is good. Reeds after the modificationprocessing are easier to bend, and can restore a state before bending after the bending is completed.

Description

technical field [0001] The invention relates to a reed straw toughening and modification treatment process for reed woven products, which belongs to the technical field of home decoration, preparation and modification of manufacturing materials. Background technique [0002] Reed Phragmites australis (Cav.) Trin.exSteud is a perennial herbaceous plant in Gramineae. It is a highly differentiated morphologically differentiated species of meadow and wetland vegetation, and is widely distributed all over the world. At present, it is used as a raw material for papermaking instead of wood, and it is known as the "second forest". [0003] The fiber aspect ratio of reed (the ratio of fiber length to fiber width) is higher than that of wheat straw, straw, corn stalk and larch, and it is an excellent papermaking material. Reed has less non-fibrous cell content, although it is not as good as wood, it is second only to cotton stalk core in Poaceae. The longitudinal tensile strength of...
