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

Embodiment 2

[0040] A kind of production equipment of container wood-plastic floor, such as Figure 4-5 Shown, comprise the first extruder 8, the second extruder 9, upper fiber network frame 10, lower fiber network frame 11, mold 12 and shaping table 13; Described first extruder 8 is used for extruding core layer, the second extruder 9 is used to extrude the cortex, and the extrusion ports of the first extruder 8 and the second extruder 9 are docked with the mold 12; the upper fiber grid 10 and the lower fiber grid 11 It is arranged on the upper and lower sides of the mold 12 ; the mold 12 includes a die head 121 , and the shaping table 13 is arranged at the outlet end of the die head 121 .

[0041] Utilize above-mentioned production equipment to prepare the method for container wood-plastic floor described in embodiment 1, comprise the following steps:

[0042] S1. Release the net: pull the glass fiber net into the mold 12 in advance, the two ends of the net stretch out from the mold 12,...

Embodiment 3

[0047] This embodiment provides an optimized reinforcement layer 3, such as Figure 6 As shown, it is a glass fiber mesh, the surface of the glass fiber mesh is provided with several support parts 31 at intervals, and the support parts 31 can be arranged on the surface of the network structure combined with the core layer, and the support parts 31 are elongated The protrusion is integrally formed with the glass fiber net, and the setting direction of the support part 31 in this embodiment is perpendicular to the running direction of the glass fiber net in the mold. When the core layer 1 drives the glass fiber net to advance together, the support part 31 is embedded in the molten state. In the core layer 1, not only the combination level of the glass fiber mesh and the core layer is improved, but more importantly, it plays a role of fixing and limiting, so that the mesh part of the glass fiber mesh is not easy to deform or bend, and the entire glass fiber mesh is flat Attached ...

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...
