High-strength straw board and preparation method thereof

Abstract

The invention relates to a high-strength straw board. The high-strength straw board comprises a straw base plate, wherein six side faces of the straw base plate are successively bonded to a sound-resistant layer, a waterproof layer and a fireproof layer through an adhesive; the straw base plate is made of wheat straws; the adhesive is a thermoplastic adhesive; the sound-resisting layer is prepared from PU matrix resin and a foam material plate which is prepared from hollow polymeric microspheres; the waterproof layer is a high-performance fiber board; the fireproof layer is a glass magnesium board. The production method of the high-strength straw board comprises the following main steps: S1, preparation of the straw base plate: 1, preparation and conveyance; 2, punch forming; 3, hot-pressing and paper-coating; and 4, cooling, segmenting and blocking; and S2, preparation of the straw board. The high-strength straw board provided by the invention has the advantages of relatively high strength, good sound-resistant effect, good fireproof performance, good waterproof performance, insect prevention and bacterial resistance and the like, can effectively replace various building panels in the current market, and can be widely applied to manufacturing exterior walls, interior walls, partition walls, roofs, doors, active houses and quick houses.

Description

Technical field [0001] The invention relates to the field of straw board production, in particular to a high-strength straw board and a preparation method thereof. Background technique [0002] my country is a big country producing food. There are more than 20 kinds of main crop stalks. The annual output is large. The planting of rice and wheat also has the problem of stalk disposal. A large amount of stalks are used as livestock feed, but livestock feed can only consume less Part of the straw, so the remaining straw is burned on the spot. Burning the straw not only wastes resources, but also causes environmental pollution. [0003] With the rapid development of the national economy, population growth and people’s living standards, the scale of economic infrastructure has expanded, and buildings have developed rapidly in the direction of diversification and technology. The demand for wood and wood-based panels has also grown rapidly. Resources are scarce and people’s awareness of e...

Problems solved by technology

[0007] The purpose of the present invention is to provide a high-strength straw board and its preparation method, which has many advantages such as high strength, good sound-proof effect, good fireproof performance, good waterproof performance, insect-proof and anti-bacterial, etc., and can effectively replace many straw boards currently on the market. Building boards can be widely used in the production of exterior walls, interior walls, partition walls, roofs, suspended ceilings, floor partitions, doors, mobile houses and fast-installed houses; and it can effectively solve the strength difference existing in straw boards , Adding mixed adhesives has poor environmental protection, high processing costs, etc.
