Antioxidant iron handicraft and manufacturing method thereof

Abstract

The invention relates to a manufacturing method of an antioxidant iron handicraft. The manufacturing method comprises the following steps that S1, the surface of an iron handicraft is coated with an antioxidant liquid with the use amount of 2-5 g / m <2>, and then is dried at 20-25 DEG C for 18-24 hours; the antioxidant liquid is prepared from the following components of gelatin, carrageenan, chitosan, citric acid, calcium lactate, ethylenediamine tetraacetic acid disodium salt, glutamine transaminase and water; S2, the surface of the iron handicraft smeared in the step 1 is sprayed with a protective coating, wherein the thickness of the protective coating is 20-50 microns; the protective coating is prepared from the following components of AlPO4, nano SiO2, nano Al2O3 and nano SiC; and S3,at the temperature of 120-140 DEG C, the iron handicraft sprayed in the step 2 is cured for 2-3 h, the antioxidant iron handicraft is obtained, and the iron handicraft has high oxidation resistance, high-temperature oxidation resistance and lasting oxidation resistance.

Description

technical field [0001] The present application relates to the technical field of iron handicrafts, in particular to an anti-oxidation iron handicraft and a manufacturing method thereof. Background technique [0002] As the most useful, cheapest, most abundant and most important metal, iron is widely used in our daily life, and with the development of society, the value of iron is getting higher and higher, and iron crafts are becoming more and more beautiful , not only can be used as ornaments for home decoration, but also can be made into many exquisite craft gifts. These iron crafts have unique craftsmanship and vivid expressions. [0003] However, iron handicrafts are exposed to the air for a long time, in contact with microorganisms and water vapor in the air, and after a long period of human touch, the grease on human hands can easily oxidize the surface of iron handicrafts, and brown-red rust appears. , the existence of these rusts will continue to absorb water and ac...
