Problems solved by technology

However, the metal still accounts for a large proportion in the metal-plastic composite floor, and there is no obvious advantage in weight; and the connection between the metal skeleton and the plastic floor is troublesome, usually through rivets, which increases the process and reduces the efficiency.

Abstract

The invention discloses a wood-plastic composite board. The wood-plastic composite board sequentially comprises a face layer, a core layer and a bottom layer from top to bottom, wherein the core layer comprises a middle core layer and a reinforcement layer, and the upper surface and the lower surface of the core layer are respectively connected with the face layer and the bottom layer through amphoteric adhesive films. A manufacturing method comprises the steps of respectively coating the amphoteric adhesive films on the upper surface and the lower surface of the core layer, then covering the face layer and the bottom layer respectively and finally performing hot pressing and pressure maintaining; performing segmented pressure reduction and exhausting or performing cooling to reach room temperature and then performing pressure relief to obtain the wood-plastic composite board. The density, strength, elasticity modulus, surface quality and other performance indexes of the wood-plastic composite board all meet the requirement of composite container base plates conforming to the international containerindustrial standard, so that the wood-plastic composite board serves as the composite container base plate and is high in designability, and the thickness and density of the face layer and the core layer are reasonably selected according to the actual demand to achieve the best economic effect.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a wood-plastic composite board, a preparation method and an application thereof. Background technique [0002] The container floor is the main stress-bearing part of the container. Due to its strict requirements on mechanical properties, it has always been made of cold and tropical hardwood panels or multi-layer composite panels made of these panels. However, hardwood has a long growth cycle and generally It will take 50 years or even longer, while the demand for container floor is increasing day by day. The depletion of hardwood resources forces us to look for better alternative resources and develop new types of container floor, which is an urgent problem we need to solve. [0003] Disclosed in the patent CN1105624A is a kind of manufacturing method of high-strength bamboo plywood, especially a kind of manufacturing method of bamboo plywood for containe...
