Container wood-plastic bottom plate and preparation method thereof

Abstract

The invention belongs to the technical field of wood-plastic plates, and particularly discloses a container wood-plastic bottom plate and a preparation method thereof. The container wood-plastic bottom plate comprises a core layer and a skin layer wrapping the core layer, a reinforcing layer is arranged between the core layer and the skin layer; the core layer and the skin layer are wood-plastic plates, the core layer is doped with short fibers; the reinforcing layer has a net-shaped structure and is made of glass fibers or metal, and the core layer, the skin layer and the reinforcing layer are integrally formed by adopting a co-extrusion process. By adding short fibers into the wood-plastic material of the core layer and arranging the reinforcing layer, the strength of the wood-plastic plate is remarkably improved, and the strength requirement of a container bottom plate is met. The skin layer wraps and protects the core layer and the reinforcing layer, the service life of the bottomplate is prolonged; the reinforcing layer is designed into a net-shaped structure, and a co-extrusion process is adopted, so that the bonding firmness between layers is greatly improved.

Description

technical field [0001] The invention relates to the technical field of wood-plastic boards, in particular to a container wood-plastic bottom board and a preparation method thereof. Background technique [0002] The container floor is installed at the bottom of the container to carry and fix the cargo. Because of its small specific gravity and easy installation and fixation, wooden boards have become the main material for container bottom boards. Most of the existing container bottom boards are bamboo and wood plywood. However, due to the excessive cutting of forest resources, wood resources are becoming less and less. Extremely restrictive. Wood-plastic composites are green and environmentally friendly materials developed in recent years with waste wood fiber powder and polymers as the main raw materials. They have both the use and processing characteristics of wood and plastics. They are often used as building templates, furniture, floors, etc., such as Being able to appl...

AI Technical Summary

Problems solved by technology

[0003] Conventional wood-plastic panels cannot be directly used as container bottom plates because their strength is far from meeting the requirements. In the prior art, reinforcing fibers are usually added to wood-plastic materials to improve The strength of wood-plastic panels, such as a hybrid wood-plastic composite material disclosed in the Chinese invention patent with the publication number CN105924720A, improves the bending strength, modulus and impact strength of the wood-plastic composite material by adding glass fibers, but this method is still Unable to make wood-plastic panels meet the container floor strength requirements
