Plastic steel hollow transportation square timber and preparation method thereof

Abstract

The invention discloses plastic steel hollow transportation square timber. The plastic steel hollow transportation square timber comprises, by mass, 50 to 80% of a main material, 25 to 30% of an auxiliary material, and 5 to 15% of a synthetic material; the main material comprises PVC resin; the auxiliary material comprises bamboo powder, wood flour, and light weight calcium powder; the synthetic material comprises a foaming agent, a stabilizing agent, and an adhesive. Advantages of a preparation method of the plastic steel hollow transportation square timber are that: finished product strength is high; the foaming agent is added, so that finished product hardness is reduced with the finished product strength is ensured, the plastic steel hollow transportation square timber possesses a certain porosity, and it is convenient to drive nails into the plastic steel hollow transportation square timber when a mould is immobilized on the plastic steel hollow transportation square timber; the plastic steel hollow transportation square timber is prepared by taking PVC resin as the main material, PVC resin is colorless, odourless, and non-toxic, possesses environmental protection flame resistance, and can be recycled, so that material loss and cost are reduced.

Description

technical field [0001] The invention relates to a plastic-steel hollow traffic wooden square; [0002] The invention also relates to a method for preparing plastic-steel hollow traffic wooden squares, which belongs to the field of construction traffic. Background technique [0003] At present, in my country's transportation and construction industries, the back reinforcement and bearing weight of the formwork are all made of wood. In the traffic, the wooden squares generally adopt the specifications of 10cm×10cm×4.0cm, and the construction industry generally adopts the wooden square specifications of 5cm×10cm×4.0cm. Douglas pine, white pine, and wooden materials are generally used for wooden squares, and wooden squares are used outdoors. After being exposed to the sun and rain, it is easy to cause deformation, or the length of the wooden square will become shorter and shorter according to the shape, and become waste. Reuse again, has caused a large amount of waste of timbe...

Problems solved by technology

Douglas pine, white pine, and wooden materials are generally used for wooden squares, and wooden squares are used outdoors. After being exposed to the sun and rain, it is easy to cause deformation, or the length of the wooden square will become shorter and shorter according to the shape, and become waste. Reuse, resulting in a lot of waste of wood
