Embodiment Construction

[0008] Embodiments of the present invention are described below with reference to the drawings.

[0009] Synthetic resins are ground into small particles, which are mixed with natural fiber materials and pressed into a certain mixture with an extruder. Here, the natural fibers consist of rice husks or sawdust.

[0010] That is to say, the diameter of synthetic resin is 0.1-0.3 mm, and the size of rice husk or sawdust is 20-50 meshes per square inch, which are dehydrated, dried, mixed, and then pressed into shape.

[0011] The preferred mixing ratio is 55%-75% of synthetic resin and 45%-25% of rice husk or sawdust.

[0012] In the surface binder used for surface bonding with the mixture, the synthetic resin accounts for 70% to 90%, and the additive accounts for 30% to 10%. The additive is made of at least one selected from glass fiber, carbonized fiber and needle-shaped structure filler.

[0013] In detail, synthetic resin composed of small particles and rice hulls or wood c...

Abstract

The present invention relates to a container board material, the mixture in the board material is made up by adopting the following method. The synthetic resin whose diameter is 0.1-0.3 mm and rice husk and wood dust whose grain size is 20-50 meshes / sq.inch are mixed together according to the ratio of 55%-75% and 45%-25% in mixer, dehydrated, dried and extruded by means of main extruder to obtain the invented first mixture, 70%-90% of synthetic resin and 30%-10% of additive are mixed, dehydrated, dried and extruded by means of secondary extruder to obtain second mixture as surface adhesive. Said two mixtures are bound together in mould. Besides, the filler consisting of resin and natural fibre material can be pressed into the interior of the board material.

Description

technical field [0001] The invention relates to a container bottom plate material, in particular to a container bottom plate material which can prevent deformation and rupture due to temperature changes and can improve product strength. Background technique [0002] Generally, the bottom of the container is made of plywood, which is easy to rot or deform due to moisture. Therefore, the bottom plate of the container needs a moisture-proof coating and requires frequent maintenance. Thus, due to the container floor, it is often necessary to do some maintenance work on the container. Contents of the invention [0003] Therefore, the object of the present invention is to provide a sheet material for the bottom plate of a container, which can overcome the above-mentioned problems in the prior art. [0004] Another object of the present invention is to provide a material for a container floor which is a mixture made by mixing natural fiber material into synthetic resin. [000...
