Description

Furniture board with UV-3D veneer

Technical Field

The utility model relates to a furniture material field, concretely relates to furniture board of UV-3D veneer.

Background

The furniture board is a double-coated wood decorative board which is mainly used for manufacturing board or board-wood furniture and the like and is prepared by taking an artificial board plain board or a decorative veneer veneered artificial board as a base material and processing the surface through artistic design and a digital coating process. Also called: the facing furniture board is painted digitally. The novel home decoration material is a new home decoration material which is gradually developed in China in recent two years, and is popular with markets and users due to the fact that surface decoration patterns of the novel home decoration material have high simulation degree and natural authenticity, the characteristics of being capable of being designed, customized, reproducible, imitated and rapidly produced and delivered, and the advantages of being capable of being environment-friendly, standardized, large-scale, customized or personalized production and delivery and the like. The product application is popularized to various application fields and different application scenes of home spaces such as wardrobes, kitchen cabinets, book cabinets, dining cabinets, wine cabinets, television cabinets, balcony cabinets, shoe cabinets and the like.

However, the new products have the disadvantages of complex material structure, complex production process, high production cost, low surface performance of parts such as paint film hardness, surface scratch resistance, crack resistance, cold and heat cycle resistance and the like, and difficult improvement, so that the comprehensive cost performance is not high, and further popularization and promotion of the products are restricted. Therefore, the performance of the new products is improved and optimized, the cost is reduced, and the effect is improved, thereby becoming a pain point in the industry.

In a conventional furniture board product system, when artificial boards such as plywood, fiberboard, and particle board are used as base materials, large quality performance differences (such as surface density, hardness, color, texture, porosity, and absorption and adhesion to paint) exist objectively due to different surface conditions and different material performance characteristics of different types of base materials, and it is necessary to adjust and reduce the differences in final product performance (such as paint film adhesion, hardness, surface scratch resistance, surface crack resistance, and surface impact resistance) caused by different base materials through a complicated coating process.

When the artificial board with decorative veneers such as the plywood with decorative veneers, the fiberboard with decorative veneers, the shaving board with decorative veneers and the like is used as the base material, the problem of standardization of the surface condition of the base material is solved, and the subsequent coating process is simplified. However, the product not only increases the veneer facing process, but also more importantly, the product reduces the surface properties of the product, such as paint film hardness, surface scratch resistance, surface cold and heat cycle resistance, surface crack resistance, surface impact resistance and the like, due to the material properties (small density, low hardness, large porosity, shrinkage and wet expansion, easy cracking and the like) of the veneer layer, so that when the product is applied to areas with obvious changes of climatic environment and use environment (temperature, humidity and the like), a higher-requirement maintenance measure needs to be adopted in a matching way, the use cost of the product is relatively higher, and the cost performance of the product is reduced.
