In the environmental protection the advantages that.Bamboo-plastic composite material is widely used in construct platform, railing, pavement, marked time, outdoor desk-chair, flower stand, Shu Chi
Deng outdoor building gardens component, it can also be used to the numerous areas such as indoor decoration, packaging, conveying tray.
Existing bamboo-plastic composite material is mostly using plastic materials such as polypropylene, polyethylene, and its degradation property is poor, and bamboo fibre
Interfacial combined function between plastics is poor, and it is low that bamboo-plastic composite material has a raw material melt flow rate in preparation process, bamboo
Fiber distributing homogeneity is poor, and product has the problems such as performance deficiency.
The content of the invention
The present invention solves the technical problem of providing, a kind of bamboo is nanocomposite moulded, can solve the problem that existing bamboo modeling is multiple
Existing weak point existing for condensation material.
In order to solve the above technical problems, one aspect of the present invention is：A kind of bamboo is provided and moulds nano combined material
The preparation method of material, comprises the following steps：
(1) plastics, titanium dioxide, glycerine and the antioxidant for weighing formula ratio by being formulated, which are added in high-speed mixer, mixes
3~10min；
(2) bamboo fibre, nano zine oxide and coupling agent that formula ratio is weighed by formula mix in another high-speed mixer
Close 20~30min；
(3) mixed raw material in step (1) is added in the loading hopper of double screw extruder, then side line adds step
(2) mixed mixture in, through melting extrusion, it is nanocomposite moulded to obtain the bamboo.
In a preferred embodiment of the present invention, it is described to be formulated the raw material for including following parts by weight of component：Plastics 40~60
Part, 30~50 parts of bamboo fibre, 5~10 parts of nano zine oxide, 10~20 parts of titanium dioxide, 5~10 parts of glycerine, coupling agent 3~5
Part, 0.5~1.5 part of antioxidant.
In a preferred embodiment of the present invention, the plastics include the PLA and starch-based bio that mass ratio is 3: 2
Plastics；A diameter of 30~300 μm of the bamboo fibre, its draw ratio are more than or equal to 500.
The beneficial effects of the invention are as follows：A kind of nanocomposite moulded preparation method of bamboo of the present invention, it is easy to operate, easily
Realize, it uses bamboo powder by the apolegamy of raw material and in matrix resin, effectively improves the combination of bamboo fibre and resin matrix
The melt flow rate (MFR) of performance and mixed material；Gained composite has 100% degradation property and excellent mechanical property,
Excellent combination property, wide market.
