Embodiment Construction

[0068] The main principles of the present invention are as shown in the following Figures 1 to 1C:

[0069] Please refer to FIG. 1 for a schematic diagram of processing a black plastic product that can transmit infrared light.

[0070] Among Fig. 1, mainly be that black pigment 11 and transparent resin 12 are mixed into black composite material 13, utilize the metallic mold 14 of an internal mold polishing again with black composite material 13, mold into a black plastic product 15.

[0071] Please refer to FIG. 1A which is a schematic diagram of the composition of the black colorant 11 .

[0072] In Fig. 1A, the composition method of black pigment 11 is to mix two or more single-color transparent pigments 111, or use a kind of fine carbon black powder to make it appear black pigment 112, the main purpose is to present black and absorb visible light.

[0073] Please refer to FIG. 1B which is a schematic diagram of the conditions of the metal mold 14 . Among Fig. 1 and Fig. ...

Abstract

A black plastic product made of transparent colorant is prepared by blending black colorant into transparent colorless resin. It has visible-light absorbing and infrared ray penetrating functions in spectrum and can be used for CCD camera with infrared band inductive system and to take photo for remote object.

Description

technical field [0001] The invention relates to a plastic that can absorb visible light and transmit infrared light, in particular to a black plastic made by mixing transparent colored pigments with colorless transparent resin and its application in infrared photography. Background technique [0002] Generally, the manufacturing method of black plastic products (plates) mainly takes opaque plastic as the carrier and mixes the inorganic black pigments into the finished processing. Most of the inorganic black pigments are mainly carbon black (Carbonblack) with relatively large particles. [0003] Carbon black is different from other pigments, and the classification of black pigments is not divided according to chemical composition or chemical structure. On the other hand, the specific production process adopted has a great influence on the performance of the pigment, so it is natural and common to use the production process as an important criterion for the classification of b...
