Detailed ways

As shown in Figures 1 to 3, the two-color building material 10 shown in the present invention is made of a two-color laminated structure by extrusion molding technology, including a plastic building material body 20 with a lighter base color and a dark plastic coating TLC30.

That is, the two-color building material 10 shown in the present invention is a two-color laminated structure formed by covering the surface of the light-colored plastic building material body 20 with the dark-colored plastic coating thin layer 30 .

Wherein, the shape of the plastic building material body 20 is the shape of a light-colored door frame or window frame building material made by extrusion molding technology, and the plastic coating thin layer 30 with a dark primary color is extruded and covered. on the surface of the plastic building material body 20 .

After the two-color building material 10 of the present invention is processed through the imitation wood grain surface, many imitation wood grain dents 35 are formed on the surface of the plastic coating thin layer 30, and the dents of the formed imitation wood grain dents 35 The depth is limited to the thickness that does not pass through the thin plastic coating layer 30 .

Therefore, the two-color building material 10 of the present invention can reflect the light base color of the plastic building material body 20 whose original color is light-colored by the imitation wood grain dent 35 formed, because the thickness is relatively thin. Comparing the color displayed by the imitation wood grain dent 35 with the surface primary color of the plastic coating thin layer 30 , there will naturally be an obvious color difference contrast effect.

Therefore, the two-color building material 10 of the present invention can naturally show the imitation wood similar to natural wood due to the effect of color difference contrast between the primary color of the surface of the plastic coating thin layer 30 and the imitation wood grain dent 35 formed. grain effect. Since the two-color building material 10 of the present invention does not need to be painted, the cost of painting can be saved.

As shown in FIG. 4 , the manufacturing method of the two-color building material 10 shown in the present invention is made according to the following steps (a) to (e).

Step (a): Prepare materials for extrusion molding of the plastic building material body 20 and the plastic coating thin layer 30, wherein the material of the plastic building material body 20 is selected from thermoplastic foaming material or thermoplastic Non-foaming material or carbon fiber material is used as the material; and the material of the plastic coating thin layer 30 is made of plastic materials such as PVC, acrylic or ABS with a dark color after deployment;

Step (b): At a mold temperature of 150°C to 200°C, extrude the plastic building material body 20 in the shape of a light-colored door frame or window frame building material with an extrusion die; The surface of the main body 20 is covered with a plastic coating thin layer 30 with a dark primary color and a thickness of 0.3 mm to 0.7 mm at the same time, so that the plastic building material body (20) and the plastic coating thin layer 30 form a two-color Two-color building materials with laminated door frame or window frame structure10;

Step (c): After cooling the two-color building material 10 produced in step (b), then carry out imitation wood grain surface processing, so that many imitation wood grains are formed on the surface of the plastic coating thin layer 30 of the two-color building material 10 Dent 35;

Step (d): After the two-color building material 10 made in step (b) is processed through step (c) imitating wood grain surface processing, the surface primary color of the plastic coating thin layer 30 of the two-color building material 10 is consistent with the formed imitation wood grain. There will be a color difference contrast effect between the grain dents 35; therefore, the surface of the plastic coating thin layer 30 of the two-color building material 10 does not need to be painted. The color difference phenomenon formed by the light primary color can naturally show the imitation wood grain effect similar to natural wood.

Step (e): Conveying the finished two-color building material with imitation wood grain surface that does not need to be painted again.
