Composite structure board with fiber unit layer attached to wood and bamboo recombined wood

Abstract

The invention provides a composite structural board with a wood-bamboo scrimber attached with a fiber unit layer. By omitting the primary hot-pressing working procedure, the comprehensive hot-pressing time is made shorter, energy consumption can be reduced, and production cost is reduced. There is no need to make fibers into a fiber board at first, and thus labor cost and consumption of adhesives and raw materials are greatly reduced. The influence on the glued construction with finished product performance by producing a fiber pre-curing layer in the fiber board production process is avoided, the sanding working procedure required due to existence of the pre-curing layer is also avoided, and consumption of the raw materials is further reduced. Moreover, equipment investment and energy consumption required in the sanding working procedure are reduced, and therefore the raw materials can be fully utilized, and manufacturing cost is greatly reduced. Meanwhile, parts of fibers are pressed into gaps of a wood-bamboo scrimber layer, and hence physical and mechanical properties of the board are improved.

Description

【Technical field】 [0001] The invention belongs to the processing technology of a composite structure board in one-time molded board, in particular to a manufacturing method of a composite structure board made of wood and bamboo recombined wood with fiber unit layers. 【Background technique】 [0002] Wood-bamboo composite plywood is usually made of wood veneer or bamboo mat, bamboo curtain, and bamboo mat veneer. The surface layer and the wood and bamboo recombined wood layer are composed of substrates. The veneer of the wood and bamboo recombined material layer is made of wood veneer, bamboo veneer, bamboo curtain, and bamboo mat veneer after drying once, applying adhesive, drying (baking glue) twice, and forming a blank with fiberboard and then hot pressing. Made of a man-made board. Because wood and bamboo are beautiful in texture, and their performance is complementary to that of fiberboard, the board has better mechanical properties and natural beauty, so it is widely u...

Problems solved by technology

The process is: first make or purchase the fiberboard produced by a professional factory, and then cut the fiberboard according to the length and width of the substrate according to the process requirements; select or make the wood and bamboo recombined material layer, and dry the veneer of the panel layer in turn (dry the inner moisture content of the raw material of the panel layer), apply the adhesive, and dry the adhesive twice (dry the adhesive); then glue the double sides of the fiberboard after trimming and form a billet, and then combine with the panel layer after the second drying or The wood and bamboo recombined material layer is hot-pressed; that is, the fiber material is formed into a fiberboard for one-time hot pressing, and the fiberboard and the panel layer and the wood and bamboo recombined wood layer are hot-pressed for the second time; The pre-cured layer needs to be sanded on the surface before leaving the factory, and then it needs to be cut once before it can be packed out of the factory; the second is that when the fiberboard arrives at the secondary processing plant for sticking wood and bamboo veneers, it needs to be cut twice before it can participate in the assembly. After hot pressing, the structural board needs to be trimmed and trimmed

The fiberboard is sanded once, trimmed twice or three times to waste materials, and secondly, the fiber must be hot-pressed to form a fiberboard. After the fiberboard participates in the formation of the blank, it must also participate in the second hot-pressing. Multiple hot-pressing wastes a lot of heat source resources. It also results in a large investment in equipment
