Drawings
Fig. 1 is a structural diagram of the plant fiber reinforced thermoplastic composite material of the present invention.
Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the following detailed description is provided with reference to the accompanying drawings:
referring to fig. 1, in a preferred embodiment of the present invention, a plant fiber reinforced thermoplastic composite material comprises a plant fiber woven fabric 1 and two layers of PP modified glue films 2, wherein the front and back sides of the plant fiber woven fabric 1 are respectively sprayed with a PP surface treatment agent 3, and the two layers of PP modified glue films 2 are correspondingly disposed on the front and back sides of the plant fiber woven fabric 1.
The plant fiber fabric 1 adopts a piece of checkered cloth or unidirectional fiber cloth, and hemp fibers can be woven into the checkered cloth by adopting a rapier loom; the unidirectional fiber cloth is warp cloth, and the fibrilia can be integrated into the warp cloth by adopting warping equipment.
The PP surface treating agent 3 is a water-soluble emulsion prepared by using maleic anhydride grafted high-fluidity PP resin as a matrix. The maleic anhydride grafted high-fluidity PP resin is P353 series of DuPont, is used for emulsifying water-distributed emulsion and surface treatment of fabric fiber fabric, and the content of the maleic anhydride grafted high-fluidity PP resin in the water-soluble emulsion is between 5 and 20 percent.
The PP modified glue film 2 is formed by pultrusion of high-fluidity PP resin grafted by maleic anhydride, and the gram weight range of the PP modified glue film is 20-200 g/sq m. The melt index range of the maleic anhydride grafted high-fluidity PP resin is 60g/10 min-200 g/10min, and the melting point is 40-180 ℃.
The fabric fiber fabric sprayed with the PP surface treating agent 3 and the two layers of PP modified glue films 2 can be compounded into the plant fiber composite material on a continuous steel belt press.
To sum up, the utility model discloses a plant fiber reinforcing thermoplasticity combined material can improve plant fiber's heat resistance, more makes things convenient for the people to use.
It will be appreciated by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as limitations of the present invention, and that changes and modifications to the above described embodiments will fall within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
