Abstract
The composite straw powder board is produced by molding flowable colloid of straw 30% and magnesia 70% in 10-30 deg.c bittern, or molding 70% straw and 30% resin through stirring. The straw powder composite board can be used as decorative boards of inner and outer walls of buildings, floors, decorative boards of rural heated brick beds and the like. The board is warm, beautiful, firm and durable, has wide application, especially has easily available straw raw materials, is convenient for popularization and application, and leads the straw to be comprehensively utilized. Because the stabilized grass is used as the raw material, a large amount of wood can be saved. And is also beneficial to protecting the environment.
Description
The present invention relates to a kind of decorative boards, particularly relate to a kind of composite sheet and manufacture method made from straw powder and magnesia thereof.
Along with rapid development of national economy, national income constantly increases, and people require to improve rapidly the living environment of oneself, and to carrying out beautifying and fitting up of other tool style in the room, the heated kang that northern country is traditional also will be decorated.In order to solicit customers or business, operating service place such as each shop, hotel and various office room have also all carried out the decoration of each tool style and features.These finishing material are mainly made with timber at present, and this has just caused the mass consumption of forest tree resource.Supply falls short of demand owing to timber, and " excessive and random lumbering " phenomenon has appearred in many places, has destroyed ecotope, causes soil erosion, even lead to water, drought evil, caused unnecessary loss for national economy and people's lives and properties.In addition, some composition boards are pressed into sawdust.But just have when sawdust has only converted timber, and quantity seldom, can not satisfy the demand.
Purpose of the present invention, be to provide a kind of outward appearance U.S., price low, without the straw composition board and the production method thereof of timber.
Purpose of the present invention realizes by following technical proposals, that is:
Computer rice straw powder plate is by the straw powder of 5-50% and the magnesia (Mgo) of 45-95%, makes with the even also moulding of 10-30 degree bittern mix.
In the computer rice straw powder plate stiffening web can be set, stiffening web can be steel wire, glass yarn, plastics silk ribbon etc.
Computer rice straw powder plate also can be made through mould molding by the straw of straw powder 5-70% and the Resins, epoxy of 30-95%.
The production method of computer rice straw powder plate is:
1, be that straw is cut into the 30-5mm segment, be put into crusher for crushing and become thread, standby.
2, get straw and the magnesia that processes by ratio of components, mix, mix all.Pour 10-30 degree bittern again into, pour in the mould after stirring, the seasoning moulding is finished product.The size shape of mould and surface detail can be as required.
The another kind of production method of computer rice straw powder plate is the straw powder that processes above-mentioned, mixes resin by proportioning, after stirring, pours in-mold molding into.
Computer rice straw powder plate has following advantage:
1, sturdy and durable, be widely used.Can be made into sheet material, floor tile etc.Different shape.Can be used as within the walls, balustrade exterior panelling, floor, heated kang face decorative sheet etc.The computer rice straw powder plate that infiltrates magnesia has fire retardation, so fire resistance is good.
2, surface smoothness is good, sends out and warms up, pigmentable.
3, production technique is simple, cost is low.
4, straw raw material is abundant.China's paddy rice cultivated area is big, behind the annual rice harvesting, and rice threshing, just remaining a large amount of straw, the needs that distribute extensively, quantity is big, can satisfy the scale operation computer rice straw powder plate, dawn purchase price is very low.Be convenient to promote the use of in the whole nation.
5, because finishing material such as alternative plank, floor can be a large amount of timber of country's saving.This helps preventing haggling, cutting down trees at random of forest, the human physical environment of depending on for existence of protection, and help preventing erosion.
Embodiment one
Computer rice straw powder plate adds magnesia 70% by straw powder 30%, with the synthetic colloidal that flows of 30 degree bittern, pours in the mould seasoning moulding into.
Embodiment two
Computer rice straw powder plate, the straw powder by 70% adds 30% Resins, epoxy, stirs, and pours in-mold molding into and makes.
Claims (3)
1, computer rice straw powder plate is characterized in that the magnesia by the straw powder 45-95% of 5-50%, with the synthetic flowable colloidal of the bittern of 10-30 degree, reenters the mould typing and makes.
2, computer rice straw powder plate according to claim 1 is characterized in that described straw is 30%, magnesia is 70%.
3, computer rice straw powder plate according to claim 1 is characterized in that being provided with in the computer rice straw powder plate stiffening web.
