However, with the increasing pressure of environmental protection, the ban on wooden pallets for railway transportation has been promulgated. Europe, the United States, Japan and other countries have strict fumigation and inspection and quarantine requirements for imported product wood packaging (including wooden pallets), and wooden pallets have been imposed. Demand has a huge impact

Embodiment 1
[0041] The concrete process of making described composite material comprises the following steps:
[0042] 1) Take 80 parts of polypropylene and 3 parts of modified color masterbatch into the hopper and measure them accurately. The mixed materials enter the first-stage twin-screw extruder through the hopper for plasticization and melting to obtain primary modified polypropylene.
[0043] 2) Add 0.5 parts of compatibilizer and 16.5 parts of antioxidant to the modified polypropylene and mix thoroughly to obtain secondary modified polypropylene.
[0044] 3) The output of the first-stage twin-screw extruder is set to 70% of the weight of the final product, and the temperature of each heating section is controlled at 200°C to 230°C, and the obtained secondary modified polypropylene is extruded through the first-stage twin-screw extruder The machine is melted to obtain a molten mixture.
[0045] 4) The automatic cutting equipment sets the glass fiber output to be 30% of the final p...

Abstract
The invention discloses an advanced composite material tray for logistics. The advanced composite material tray for the logistics comprises an upper faceplate and a lower faceplate. The upper faceplate and the lower faceplate are formed by mould-pressing a composite material LFT-D, wherein the composite material is prepared by a fusing mixture of which the weight percentage is 60-80% and a reinforcing material in equal length of which the weight percentage is 20-40%. Through an advanced production technology and a novel product design, the LFT-D tray has the good falling resistance and impactresistance by using a mode of striking from the high-dimensionality to the low-dimensionality, namely a mode of the dimensionality-reducing striking. The market promotion and the selling are performed, so the market potential is large.
Description
technical field [0001] The invention relates to a pallet, in particular to a logistics pallet of a novel composite material. Background technique [0002] In recent years, China's logistics industry has developed rapidly, with an average annual growth rate of more than 15%. Experts predict that in the next few years, the average annual growth rate of China's logistics market will maintain 20%, and the annual new pallet consumption will exceed 20 million pieces. "High efficiency, energy saving, environmental protection, and low cost" will be the main characteristics of the logistics industry in the future. This is not only a golden opportunity for development, but also a huge challenge for the late-starting plastic pallet manufacturing industry. [0003] For a long time, the pallets used in China's logistics industry are mainly wooden, accounting for 90% of the total domestic pallets. However, with the increasing pressure on environmental protection, the ban on wooden palle...
