Abstract

The invention is a bamboo and wood composite container bottom plate manufactured by one-step hot pressing and having high elastic modulus and a manufacture method thereof. The structure of the plate is that materials for an upper surface and a lower surface are respectively 3-5 layers of thin bamboo curtains dipped with phenolic glue or melamine glue; an inner layer is a layer of transverse veneer and still inner layers are structural particleboards; or inner layers are all wood veneers; or the longitudinal and transverse wood veneers are replaced by a partial of bamboo curtains; and the number of layers and the fiber direction of the wood veneers or the bamboo curtains are determined by structural principles of wood container bottom plates. The plate has advantages in that by utilizing the outermost layers of bamboo curtain surfaces which are pressed densely and have a high elastic modulus, the elastic modulus of the bottom plate is increased greatly and the energy consumption is small. In addition, the surface bamboo curtains are characterized by low absorbent expansion rate, high hardness and good wear-resistance. Raw material sources of the bottom plate are widened. The finished composite container bottom plate has stable quality, and the performance indexes of the bottom plate, such as strength, elasticity modulus, etc., measure up to the technical requirements of the international container industry.

Description

technical field

[0001] The invention relates to a bamboo-wood composite container floor with a high elastic modulus formed by one-time hot pressing with multi-layer bamboo curtains as the surface layer and a manufacturing method thereof, which belongs to the technical field of wood-based panel manufacturing in the wood industry. Background technique

[0002] The main load-bearing area of ​​a container is the bottom plate. The container manufacturing industry requires the bottom plate to have high mechanical properties, appearance quality, impact resistance and aging resistance. The existing bamboo-wood composite container floor has two forms: the surface layer of patent ZL 98111153.x is a kind of bamboo-wood composite container floor with impregnated paper and bamboo mat, and the surface layer of another patent ZL 03152841.4 is formed by high-pressure hot pressing A thin layer of high-density bamboo is used as the surface and back layer, and then combined with structural par...
