Plant panel and preparation method thereof

Abstract

The invention relates to the technical field of artificial panels, in particular to a plant panel prepared from plant rattans, stems, leaves and stalks and a preparation method thereof. The plant panel is prepared from the following raw materials in percent by weight: 50-70% of plant rattans, stems and leaves and stalks, 10-25% of an adhesive and 20-25% of water. The plant panel is wide in sourceof raw materials, stable in performance, good in nail-holding power, high in strength, environmentally-friendly and energy-saving.

Description

technical field [0001] The invention relates to the technical field of artificial boards, in particular to a plant board made of plant vine stems and stalks and a preparation method thereof. Background technique [0002] The output of rural straw, especially crop straw, in my country is huge. The straw produced in the last century can be used as firewood, so it enters the environmental cycle very well. series of questions. During the summer harvest and autumn and winter every year, a large amount of wheat and crop straws burned in the fields produce a large amount of thick smoke, which not only aggravates the serious environmental problems caused by the smog, but also poses safety hazards and causes fires.

AI Technical Summary

Problems solved by technology

Every year during the summer harvest and autumn and winter, a large amount of straw such as wheat and crops burned in the field produces a large amount of thick smoke, which not only aggravates the serious environmental problems caused by the smog, but also poses safety hazards and causes fires

Therefore, in order to solve various environmental problems caused by burning straw, two ways of digesting straw have been developed: first, the straw is returned to the field through the stomach, and the straw has been cut, bundled, transported, guillotined, and ammoniated. As animal husbandry feed, livestock manure is applied to the ground after the abdomen. This method is time-consuming and laborious, and the amount of processed livestock is limited, so it is difficult to realize large-scale digestion of straw. Second, mechanized straw is returned to the field. Shredding and returning to the soil not only effectively supplements the soil fertility, improves the soil structure, solves the adverse consequences caused by the excessive use of chemical fertilizers, saves time and labor, and creates conditions for solving the problem of excess straw on a large scale. The first half of the leaves or straw can rot within a year or two, but the lower part of the straw and the roots are hard to rot. Finally, the method of burning the land is used to solve the problem. At present, straw burning is strictly prohibited by the state. Therefore, the disposal of crop stalks has become a big problem. Now more solutions are to gather these stalks or roots to the fields. However, as time goes by, the crop stalks and roots gathered on the fields become more and more More and more, not only will it affect normal farming, but these straw roots will also flow into the river with the rain, which will have a great impact on the river water, especially in the watery places in the south

In addition, in recent years, the weeds on the edge of the rural fields have been overgrown, no one manages and cleans them, and the field roads are full of fields, which has a great impact on agricultural cultivation. Therefore, if the processing and reuse of waste straw can be realized, it can be avoided. The environmental problems encountered in the process of dealing with straw pairs can also realize the utilization of straw and turn waste into treasure

[0003] Although there are many technologies for making straw boards from straws, formaldehyde-based adhesives are generally used in straw boards, so the finished products will release more or less free formaldehyde. When the free formaldehyde content exceeds a certain limit, it will affect human health. In addition, in the current straw board making process, high-temperature pressurization is often used to form the board. The glue needs to be cured at high temperature, and the material is formed under pressure, which consumes a lot of energy. At the same time, because the main material of the straw board is straw, its thermal conductivity is poor. The thickness of the formed sheet is greatly limited
