摘要:
大幅面、连续化是推动浸渍薄木新型装饰材料产业化生产应用的关键。以成卷重组装饰单板(人造薄木)为材料、三聚氰胺甲醛树脂(MF)为浸渍液体,在浸渍纸工业化生产线上开展浸渍试验。介绍了重组装饰单板连续化浸渍工艺,观察了重组装饰单板浸渍前后表面微观形貌,并针对胶合板、刨花板和纤维板进行热压贴面,研究浸渍重组装饰单板热压工艺参数,包括热压温度、热压时间和热压压力,测试了贴面胶合强度及其耐久性。结果表明:工业化浸渍的重组装饰单板普适于胶合板、刨花板和纤维板基材的饰面,贴面板的表面胶合强度均高于1 MPa(纤维板表面胶合强度最高,其次是胶合板,最后是刨花板), 而且具有优异的贮存耐久性, 热压贴面温度宜控制在180~190 ℃、时间80~100 s、压力不低于2 MPa。研究表明, 直接采用传统浸渍纸生产设备实现大幅面装饰薄木的工业化、连续化浸渍完全可行, 浸渍后重组装饰单板反映出明显的浸填效果,树脂覆面效果类似于浸渍纸,为推进浸渍薄木装饰材料的规模化生产及应用提供了参考。
Abstract:
Thin veneer, including natural thin veneer and reconstituted decorative veneer, is commonly used to decorate the surface of woodbased panels and products. The traditional thin veneeroverlaying process requires the addition of adhesive to overlaying and the painting decoration, which is cumbersome and the release of organic volatiles can cause longterm indoor air pollution. Therefore, in recent years, the resinimpregnated thin veneer has been utilized as a new highgrade decorative material. As a new decorative material, the continuity and largedimension are crucial issues for the industrial production and application of the resinimpregnated thin veneer. In this research, an industrial production line of the resinimpregnated paper with melamine formaldehyde resin (MF) was used to impregnate the synthetic resin on the reconstituted decorative veneer. The continuous impregnation process of the reconstituted decorative veneer was introduced, and the micromorphology of the surface of the decorative veneer before and after impregnation were compared. The hotpressing process parameters including the hotpressing temperature, hotpressing time, and hotpressing pressure were studied to make the resinimpregnated reconstituted decorative veneer. Through the observation of the microstructure appearance, it was found that the resinimpregnated reconstituted veneer reflected the obvious impregnation quality which was similar to the impregnated paper. The surface bond strength of the resinimpregnated thin veneer overlaid plywood, particleboard, and fiberboard substrates were examined. The results showed that the resinimpregnated thin veneers could be widely applicable to such wood composite panels and the surface bond strengths of them were higher than 1 MPa, in which, the overlaid fiberboard owned the highest surface bond strength and followed by the overlaid plywood. It was also necessary to investigate the storage durability of resinimpregnated thin veneers by testing surface bond strength and the results indicated that resinimpregnated thin veneers had prominent storage durability. Compared with the resinimpregnated thin veneer stored at room temperature, the resinimpregnated thin veneer stored at low temperature was more durable. The optimized hotpressing technical parameters were the temperature of 180-190 ℃, for 80-100 s, at a pressure level of 2 MPa. The above results confirmed that it was technical feasible to continuously produce large dimension resinimpregnated veneers. This research can provide valuable information to promote the development of the large scale production and application of resinimpregnated thin veneers.
