Problems solved by technology

[0002] Containers are used as a tool for loading and transporting goods and are convenient for loading and unloading with mechanical equipment. They are widely used in various fields. There are direct scratches and impacts between the container and the container. At present, the container floor is mostly wood or bamboo. Although the price is low, it is not corrosion-resistant and is easily eroded by water vapor during sea transportation. The bamboo-plastic composite board material has high strength and corrosion resistance. , has gradually become used to manufacture container bottom plates, but its impact resistance is not good, it is prone to damage during loading and unloading of goods and transportation bumps, and its service life is short

Embodiment 1

[0027] A bamboo-plastic composite board material for a container floor, comprising the following components in parts by weight:

[0028] 60 parts of MMA grafted modified bamboo pulp fiber, 25 parts of HDPE, 25 parts of LLDPE, 0.5 part of sarin resin, 2 parts of maleic anhydride grafted polypropylene, 0.5 part of polyethylene wax, and 8 parts of thermotropic liquid crystal polymer.

[0029] Wherein, the preparation method of MMA graft modified bamboo pulp fiber is as follows:

[0030] Add 5g of DMAP and 15mL of triethylamine into 500mL of THF, stir for 20min, blow nitrogen, then add 10g of bamboo pulp fiber, continue stirring for 20min, cool the reaction solution to 0°C, add 10mL of 2-bromoisobutyryl bromide, After returning to room temperature and reacting for 20 minutes, the temperature was raised to 65°C for 20 hours and then filtered. The resulting solid was extracted with absolute ethanol for 10 hours and then dried to obtain 12 g of intermediates. Copper bromide and penta...

Embodiment 2

[0036] Substantially the same as Example 1, the difference is that the prepared bamboo-plastic composite board material for the container floor includes the following components in parts by weight:
