Description

Composite board and production process thereof
Technical Field
The invention belongs to the technical field of plates, and particularly relates to a composite plate and a production process thereof.
Background
The plate is a main material in the industries of furniture, construction and the like, and compared with a single-layer plate, the multi-layer plate has the advantages of good structural strength and stability, light weight, high strength, good elasticity and toughness, impact and vibration resistance, easiness in processing, coating and insulation and the like, and becomes a common material in the plate.
The multi-layer board in the current market can only use the wooden board due to the influence of the production process, and the wooden board is easy to expand with heat and contract with cold in the use process, is easy to deform and mildew after being affected with damp or heated, and has the problems of poor layering, cracking, bulging, bending and fireproof performance and the like.
Disclosure of Invention
The invention aims to provide a composite board and a production process thereof, and solves the problems that a wooden board is easy to expand with heat and contract with cold in the using process, is easy to deform and mildew after being affected with damp or heated, and has poor layering, cracking, bulging, bending and fireproof performances.
The invention provides a composite board, which comprises a spraying layer, wherein a first alloy layer is arranged below the spraying layer, a substrate layer is arranged at the lower part of the first alloy layer, and a second alloy layer is arranged at the lower part of the substrate layer. Through setting up the spraying layer, low in manufacturing cost, top layer intensity and coefficient of wear all have the improvement, and the transparency and the third dimension that can strengthen panel are stronger. Through setting up first alloy-layer, its abrasion resistance improves greatly, and fire prevention, dampproofing, corrosion-resistant, stable in structure non-deformable have prolonged product life.
Through setting up the second alloy-layer, make the product structure more stable, reduced expend with heat and contract with cold coefficient, the probability that the fracture warp has significantly reduced uses with the cooperation of first alloy-layer to make panel more level and smooth, and fire behavior improves. The substrate layer and the alloy layer are adopted, the manufacturing cost is low, the elasticity of the wood board is kept, the subsequent processing is easier, all waste materials can be recycled, the waste of resources can not be caused, and the pollution to the environment is reduced.
Further, the thickness of the first alloy layer and the second alloy layer is 0.5mm-1.5 mm. Through the thickness that sets up first alloy-layer and second alloy-layer, avoid thickness to lead to the panel intensity not enough excessively, perhaps thickness is too thick leads to the panel degree of difficulty to increase that flattens.

placing the first alloy layer (2) on a press, coating an environment-friendly adhesive, covering the spray coating layer (1), and then pressing tightly and pressing by using the press;
and (3) placing the board after the base material is pressed on a press, then coating the environmental-friendly glue, laying the board after the pressing and the pressing on the board after the base material is pressed, and finally performing the fitting and the pressing by using the press.
7. The process for producing a composite sheet material as claimed in claim 6, wherein the base material pressing temperature is 90 to 100 ℃ and the pressure is 12 to 16 Mpa; the pressing temperature is 160-; the temperature of the fitting and pressing is 100-120 ℃, and the pressure is 5-8 Mpa.
8. The production process of the composite board as claimed in claim 6, wherein when the substrate layer (7) is a three-layer board, the three-layer board is glued and then placed in a press, and then the three-layer board is pressed, wherein the pressing temperature of the three-layer board is 110-140 ℃, and the pressure is 12-16 MPa.
9. The production process of the composite board as claimed in claim 6, wherein the environment-friendly glue is triamino environment-friendly glue.
10. The production process of the composite board as claimed in claim 6, wherein the environment-friendly glue is mixed with an antibacterial agent and a flame retardant.
