Preparation method of portable and movable straw sheet and plate prepared by preparation method

Abstract

The invention discloses a preparation method of a portable and movable straw sheet and a sheet prepared by the preparation method. Main raw materials for the straw sheet comprise agricultural straws or wild straws, asphalt and/or polymer and/or rubber material, the preparation method is characterized in that harvested and spike-removed straws can be used as raw materials for production of the sheet and thus the production process is simplified; a portable production device can be moved to the field for on-the-spot production, the stress and cost in collection, transportation and warehousing of the straws are reduced and the radiation scope of the device is expanded. The prepared sheet can be used for laying traffic auxiliary roads so as to reduce the consumptions of asphalt and gravel; and can also be used as base plates for sheets such as waterproof sheets and building templates and renewable wood fiber resources which are most abundant on the earth are fully utilized. The sheet is prepared from the straws, a large amount of agricultural straws are consumed and problems caused by the waste straws are alleviated, especially the problems of air pollution and haze due to the traditional burning of straws in the fields by farmers are solved, the preparation device and process are simple and convenient, affordable and strongly feasible and rural farmers can be organized to process the straw sheet.

Description

technical field [0001] The invention relates to the field of straw boards, in particular to a convenient mobile straw board preparation method and the prepared boards. Background technique [0002] According to the report of the United Nations Environment Program, various crops planted in the world can provide about 2.9 billion tons of various straws every year, of which less than 20% are utilized. As a large agricultural country, China produces hundreds of millions of tons of crop straw every year, except for the energy needed by rural residents, most of which are discarded at will or burned in the fields. The smoke from straw burning contains a large amount of air pollutants, which has a negative impact on China's traffic safety, ecological environment, and human health and safety. Although the government has issued repeated orders requiring farmers not to burn straw, there is no more reasonable and effective way to deal with it. Consuming such a large amount of straw, ev...

Problems solved by technology

[0003] At present, the utilization of straw includes gaskets, stacking manure in the field, fermentation to produce biogas, silage as feed, biomass ethanol production, sugar production, etc., and there is also the production of processed straw and other additives into building boards. Its industrial scale Most of the production processes are relatively complicated, the one-time investment is large, the transportation cost of straw is too high, and the collection range of raw materials is not large; in addition, due to the scattered distribution of straw and strong harvest seasonality, straw collection, storage and transportation have become the main methods for large-scale utilization. bottleneck
