Process for producing highly heat-resistant orange type inorganic pigment for Polyamide and highly heat resistant orange type inorganic pigment for Polyamide produced by this process

摘要

The present invention relates to a method of producing a highly heat-resistant orange type inorganic pigment for polyamide which is produced by firing a mixture of inorganic material powder including titanium dioxide (TiO_2), zinc peroxide (ZnO_2) and a stannic oxide (SnO_2), and a highly heat-resistant orange type inorganic pigment for polyamide produced thereby. According to the present invention, the highly heat-resistant orange type inorganic pigment is an environmentally friendly inorganic pigment which has excellent compatibility with a polyamide resin used as an orange colored material for automobile components such as a battery pack, a high voltage cable and peripheral parts thereof having a highly heat-resistant and high rigidity material applied thereto, and which has excellent heat resistance not to be carbonized or discolored during processing of the resin at high temperatures. Unlike an existing method of producing an orange type inorganic pigment, the method of the present invention has an effect of obtaining a high productivity by firing a mixture of the inorganic material powders and producing the orange type inorganic pigment such that the orange type inorganic pigment can be produced by a simple method.
