Abstract
The utility model relates to a crop straw wood-plastic composite board. The board is characterized in that the upper surface and the lower surface of a straw board core are respectively coated with veneering glue, and veneers are respectively stuck on the veneering glue. The straw board core is protected by the veneer, so the physical strength is greatly increased, and the impact resistance can be improved by 20kg/cm2The veneer is 1-8 mm thickDense plywood, polyurethane impregnated paper or PVC plastic board; the coating adhesive is E1Special grade MVF glue, high-strength latex or all-purpose adhesive; the temperature of the veneering is as follows: 170-180 ℃; the veneering time is as follows: 7-8 minutes. After the composite board is processed by compounding, the straw artificial board not only can greatly enhance the physical strength, but also has some advantages of a wood board and the wood artificial board, and the board also has the advantages of the wood board and the wood artificial board, namely the straw artificial board has the advantages of light weight, low price, environmental protection, high economic benefit, wide raw material supply and the like.
Description
Affiliated technical field
The utility model relates to a kind of artificial composite plank, especially a kind of crop stalk art plastic clad plate.
Background technology
China is large agricultural country, the surplus of annual crop stalk class accessory products is up to more than 10 hundred million tons, this is a huge reproducible resource, making wood-based plate with straw is that the straw industrialized utilization has the technology of market development potentiality and industrialization prospect most, it is one of optimal path that solves the crop stalk comprehensive utilization, but, compare with wood based panel and wood-base fibre and particle panel material, also there is certain shortcoming in its straw wood-based plate on its physical strength performance, its anti-impact force intensity does not also reach the level of wood based panel and wood-base fibre and particle panel material, and some some problem is physically satisfactorily resolved so far as yet.
Summary of the invention
In order to solve the problems such as physical strength of straw wood-based plate, the utility model provides a kind of composite board of wood and plastic produced from stalk of crop, this composite plate is by after the Compound Machining, this straw wood-based plate not only can strengthen its physical strength greatly, some advantages that can have wood based panel and wood-base fibre and particle panel material, and this plate also has wood based panel and the unexistent advantage of wood-base fibre and particle panel material, promptly has advantages such as the light weight that is possessed of straw wood-based plate, inexpensive, environmental protection, economic benefit height, raw material supply be extensive.
The technical scheme that its technical problem that solves the utility model adopts is: this composite plate comprises thick china, straw plate core and overlay glue three parts; It is characterized in that: the upper and lower faces at straw plate core scribbles overlay glue respectively, is pasted with thick china on the overlay glue respectively.During use, straw plate core has been owing to there has been the protection of thick china, thereby physical strength increases greatly, can improve impact resistance 20kg/cm
2More than, its thick china is that thickness is highly dense glued board, poly hydro ammonia impregnated paper or the PVC plastic plate of 1mm～8mm; Its overlay glue is E
1The special-purpose MVF glue of level, high-strength latex or all-purpose adhesive; The veneer temperature of its hot pressing is: 170 ℃～180 ℃; Its veneer time is; 7～8 minutes.
Its beneficial effect: this composite plate is by after the Compound Machining, this straw wood-based plate not only can strengthen its physical strength greatly, some advantages that can have wood based panel and wood-base fibre and particle panel material, and, this plate also has wood based panel and the unexistent advantage of wood-base fibre and particle panel material, promptly has advantages such as the light weight that is possessed of straw wood-based plate, inexpensive, environmental protection, economic benefit height, raw material supply be extensive.
