preparation example Construction

[0047] In a second aspect, the present invention also provides a method for preparing a metal-resin composite, wherein the preparation method includes the following steps:

[0048] (1) treating the metal surface to form nanopores on the metal surface;

[0049] (2) contacting the resin composition with a metal surface with nanopores formed on the surface, and then direct integral injection molding;

[0050] Wherein, the resin composition is the resin composition described in any one of the above.

[0051] According to the preparation method of the present invention, in step (1), the aperture of the nanopore can be 10-100nm, and when the nanopore formed on the surface of the metal is within the above-mentioned limited range, it is possible to make the fiber, carbon Black pigments can more smoothly enter the nanopores on the metal surface, which can effectively enhance the strength of the bonding layer, thereby improving the bonding force between the resin and the metal.

Embodiment 2

[0073] This example is used to illustrate the resin composition, the metal-resin composite and the preparation method thereof of the present invention.

[0074] (1) The resin composition contains 59.5% by weight of polybutylene terephthalate (PBT), 35% by weight of glass fiber, 3% by weight of toughening agent, 0.5% by weight of antioxidant, 0.5% by weight carbon black pigment, 0.8% by weight dispersant oxidized polyethylene wax, 0.8% by weight flow modifier; wherein, the ratio of the content of the dispersant to the flow modifier is 1:1;

[0075] (2) Treating the metal (aluminum alloy) surface to form nanopores of 100 nanometers on the metal surface;

[0076] (3) The resin composition in step (1) is contacted with the metal surface on which nanopores are formed on the surface, and then directly integrally injection-molded, and the prepared metal-resin composite is marked as S2.

[0077] The performance test of S2 is shown in Table 2.

Abstract

The invention relates to the field of macromolecular materials, and discloses a resin composition, a metal-resin composite and a preparation method of metal-resin composite, wherein the resin composition is prepared from matrix resin, fibers, a carbon black pigment, a dispersant and a flow modifier; and the content ratio of the dispersant to the flow modifier is 1:(1 to 2), preferably 1:(1 to 1.5), more preferably 1:(1 to 1.2). Under the synergistic effect of the two materials, i.e. the dispersant and the flow modifier, the dispersibility of solid phase materials such as the fibers and the carbon black pigment and the flowability of the composition can be effectively improved, so that the fibers, the carbon black pigment and the like can more smoothly enter the nanopores in the surface ofmetal, effectively enhancing the strength of a bonding layer, thereby increasing the bonding force between the resin and the metal.
