Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a straw wooden ceramic root irrigation pipe and its preparation method and application, which overcomes the difficulty in preparing wooden root irrigation pipes with complex shapes by traditional molding techniques, and other processes The cost of wood ceramics is too high. This method first dissolves phenolic resin in alcohol, then adds straw for ultrasonic impregnation, and after drying, it is ball milled with clay and dextrin at a low speed, then adds silica sol and carbon fiber, and stirs to form a ceramic slurry. Inject into a stainless steel mold, dry and demould to form an underground root irrigation tube blank, and finally sinter under the protection of a static atmosphere to prepare an underground root irrigation tube with a complex shape

preparation example Construction

[0037] A method for preparing a straw wood ceramic root irrigation pipe, comprising the following steps:

[0038] Step 1: According to the formula quantity, add phenolic resin with a particle size of 200 mesh into 90% alcohol to make a solidification solution, put the solidification solution in a sealed beaker, stir at a low speed for 10 minutes to fully dissolve, and prepare a solution;

[0039] Step 2: In order to avoid the interference of impurities such as soil particles on the straw, the straw is washed with water and then dried, and then the straw of the formula is crushed into particles with a particle size of 50 mesh by a pulverizer, and the straw is dipped into the solution obtained in step 1, and dipped into The time is 1h; after the impregnation is completed, place it in a blast drying oven at 65°C to dry to remove alcohol and form a solidified block;

[0040] Step 3, put the solidified block obtained in step 2, the clay and dextrin in the formula amount into a ball...

Embodiment 1

[0048] The present embodiment provides a straw wood ceramic root irrigation pipe, which comprises the following raw materials in terms of mass percentage: 10% phenolic resin, 20% alcohol, 10% straw, 7% clay, 3% dextrin, 48% silica sol and Carbon Fiber 2%. The preparation method of straw wood ceramic root irrigation pipe comprises the following steps:

[0049] Step 1: According to the formula quantity, add phenolic resin with a particle size of 200 mesh into 90% alcohol to make a solidification solution, put the solidification solution in a sealed beaker, stir at a low speed for 10 minutes to fully dissolve, and prepare a solution;

[0050] Step 2: In order to avoid the interference of impurities such as soil particles on the straw, the straw is washed with water and then dried, and then the straw of the formula is crushed into particles with a particle size of 50 mesh by a pulverizer, and the straw is dipped into the solution obtained in step 1, and dipped into The time is 1h...

Embodiment 2

[0056] This embodiment provides a kind of stalk wooden ceramic root irrigation pipe, which comprises the following raw materials in terms of mass percentage: 13% phenolic resin, 19% alcohol, 10% straw, 7% clay, 3% dextrin, 46% silica sol and Carbon Fiber 2%. The preparation method and condition parameters of straw wood ceramic root irrigation pipes are the same as those in Example 1.

Abstract

The invention discloses a straw wood ceramic root irrigation pipe and its preparation method and application. The raw materials of the root irrigation pipe include phenolic resin, alcohol, straw, clay, dextrin, silica sol and carbon fiber, and are prepared by pouring molding with a specific structure. The green body is sintered under the protection of nitrogen to make the underground root irrigation pipe. The method can prepare underground root irrigation pipes with required shapes according to actual needs, can realize fast connection of underground irrigation pipes, and greatly reduces preparation and installation costs. At the same time, the root irrigation pipe has good environmental coordination. After reaching the design life, it can be directly crushed and returned to the field without recycling, which not only saves recycling costs, but also effectively improves the soil structure.

Description

technical field [0001] The invention belongs to the field of water-saving irrigation, and in particular relates to a recycling-free and easy-to-connect straw wood-ceramic underground root irrigation pipe and a preparation method and application thereof. Background technique [0002] At present, underground irrigation pipes are generally made of plastic or rubber products, and the recycling problem is more complicated. In order to achieve the purpose of easy recycling or no recycling, it is necessary to use pipeline products with low strength and no pollution to the environment. The patent "A Natural Mineral Modified Wood Ceramic and Its Preparation and Application" (application number: 201810163839.5) discloses a natural mineral modified wood ceramic and its Its preparation method has good adsorption effect, but the pore size range of the material is basically between 0.3-5.2um, and the pore size is too small; at the same time, the flexural strength is generally 8-9MPa, and...
