Description of the invention: [Technical field to which the invention belongs] The present invention relates to a two-color building material structure with an imitation wood grain surface, especially a thin plastic coating layer covering a light-colored plastic building material body. Two-color building material structure with imitation wood grain surface. [Previous technology] According to the building materials such as door frames or window frames made of plastic or carbon fiber, in order to imitate the quality of wooden building materials, the surface processing will be used to form a wood-like surface, and then a layer of paint will be used to paint. After the wooden road test that highlights the imitation wood grain surface, the surface of such building materials as door frames or window frames made of petals or carbon fiber can exhibit the effect similar to natural wood. However, due to the wood-like surface of this custom-made building material or carbon fiber building material, you must show the wood-like effect after painting. It is actually not economical in terms of the burden of extra expenses. The cost of the system [Abstract] According to Jian Wei, the main purpose of the present invention is to reveal a two-color construction handle with an imitated wood grain surface covered with an ice-colored plastic coating on the base color _ light or carbon surface. And constitute-a kind of two-color laminated building material structure, through the wood-like sister surface plus coating of stolen wood _ and _ Gannen = = too = Γ Yingjiajiao or the background color of the carbon fiber building material body, so that the cover sound = The primary color of the recess t and the surface of the plastic coating layer is therefore different. Therefore, it is not necessary to: 'paint the job' to show the advantages similar to natural too cost. ，，，， 果 ， There is no need to modify the paint and save the secondary purpose of this book is to show the surface-a kind of imitation wood grain surface ^ The surface passes the imitation wood grain surface plus% structured door frame «frame and other building materials. The effect is similar to natural 1240776 after the paint operation. [Embodiment] Call the first to third pictures. The two-color building material (10) shown in the present invention is made by extrusion molding technology. A two-color laminated structure includes-a light-colored plastic material body 职) and-a dark plastic coating thin layer (30). That is, the two-color building material (10) shown in the present invention is a system A two-color laminated structure formed by covering a surface of a light-colored plastic building material body (20) with a thin plastic coating layer (30) of primary color. Guan Jia. The plastic building material body (20 ) Shape, which is made by the extrusion molding technology in the shape of the door frame or frame building material with a primary color of g, and the primary color is a dark _ petal covering thin layer (30), which is shot over the plastic building material body (2 〇) on the surface. The two-color building material (1) by Takimoto Iki was treated with imitation wood grain surface, On the surface of the plastic covering deaf layer (30), many imitation wood grain dents are formed, and the depth of the indentation of the imitation wood grain embossing (35) is formed so as not to pass through the petals. (3_Thickness is limited. Therefore, the two-color building material of the present invention can be formed by the imitation wood grain indentation. Because the thickness is thinner, it will be more inverse_the petal building material body with a light color.) The pale background color makes the color system displayed by the imitation wood grain indentation 与 compare with the original color of the surface of the translucent thin layer ⑽, which naturally has a clear color contrast effect. ΜΙ 二 ί 发 _ 双 _ ( 10) By the surface color of the plastic coating thin layer (3G) and === thin) The material of the main body of the building material is the 'extractable foaming material f', or the thermal foaming material, or the carbon fiber material 1240776, which is color-matched; and the plastic is covered with a thin layer (30 ) Material, use the plastic material such as PVC, acrylic or ABS with dark color as the material; Step (b) · At the mold temperature of 15 (rc 200t: Next, the plastic building material body (20) in the shape of the door frame or window frame building material with a light primary color is extruded with an extruder; and at the same time, the surface of the plastic building material body (20) with a light primary color is simultaneously molded. Covered with a layer of plastic coating thin layer (30) with a dark original color and a thickness of 0.3mm ~ 0.7mm, making the plastic building material body (20) and the coating thin layer (3G) -structure button two colors Laminated door frame or window frame structure of the two-color building material (10); Step (C): After cooling the two-color building material (10) made in step ⑹, then proceed with imitation wood grain surface processing treatment, so that the two-color building material (10 ) The surface of the plastic-coated thin layer (30) is formed with many woodgrain-like indentations (35); Step ⑷ ·· The two-color building material produced as a result of Step ⑽ is processed after the woodgrain-like surface processing in Step (c) The color difference between the surface primary color of the plastic coating thin layer (3Q) of the two-color building material (1G) and the imitation wood grain dents (35) formed; therefore, the plastic of the two-color building material (10) The surface covered with a thin layer (30) does not need to be painted. The imitation woodgrain dents (35) are used to reflect the The color difference phenomenon formed by the light primary color of the plastic building material body (20) can naturally show the effect of imitating wood grain similar to that of natural wood. Step (e): Convey the two-color building material without imitating the wood grain surface. Finished product. [Brief description of the drawings] The first diagram is a schematic diagram of a two-color building material with an imitation wood grain surface shown in the present invention. The second figure is a partial enlarged view of the two-color building material shown in the first and second figures, showing the two-color laminated material structure of the present invention is composed of a two-layer dark plastic coating layer covered with a light-colored plastic building material body. Constituted above. The second picture is an enlarged partial cross-sectional view of the two-color building material shown in FIG. 1. Effect. The fourth figure is a manufacturing flowchart of the two-color building material shown in the present invention.
