Problems solved by technology

[0002] Red pigments are widely used in painting, paint, plastic, construction, etc., but the red pigments on the market cannot be preserved for a long time after painting. During the preservation of paintings, due to the influence of light and suspended particles in the environment, it will make The red pigment gradually fades and loses its luster, and affected by the humidity in the air, the painting is easy to mildew, making the painting lose its preservation value
[0003] The existing patent document CN 103483923 A discloses a quick-drying and durable red acrylic paint, which specifically discloses mixing Pigment Red 202 with bentonite, mica powder, dispersible latex powder, hydroxypropyl starch ether, methyl acrylate and water , Pigment Red 202 is an existing red pigment product on the market, adding several ingredients for simple mixing, little change in the characteristics of Pigment Red 202 itself, so the red pigment disclosed in the patent document can dry quickly, but the storage time is too long It can only reach about 2 years, and it will not significantly prolong the preservation time of paintings

Abstract

The invention mainly relates to the technical field of pigment processing, and discloses a lightfast mildew-resistant red pigment. The red pigment is prepared from the following raw materials: 17-19 parts of iron thiocyanate, 11-13 parts of zeolite powder, 7-9 parts of hydroxyethyl cellulose, 6-8 parts of nanometer titanium oxide, 6-8 parts of fumed silica, 3-5 parts of sulfamic acid, 1.4-1.6 parts of silicone oil, and 5-7 parts of water. The lightfast mildew-resistant red pigment provided by the invention has bright color, is fine and bright, has good fluidity, makes painting smooth and beautiful, has strong tolerance to light and heat, inhibits mold growth, keeps the painting in light for 8 years without fading, and can significantly extend the preservation value of the painting. The zeolite powder is heated at a high temperature and undergoes long-term heat preservation, the porosity and adsorption property of the zeolite powder are improved, so that the pigment can be quickly dried, the adhesion of the pigment to a base material is increased, and the pigment can be prevented from falling off.

Description

Technical field [0001] The invention mainly relates to the technical field of pigment processing, in particular to a light-resistant and mildew-resistant red pigment. Background technique [0002] Red pigments are widely used in painting, paint, plastics, construction, etc. However, the red pigments currently on the market cannot be stored for a long time after painting. During the preservation of the painting, due to the influence of light and suspended particles in the environment, it will cause The red paint gradually fades, loses its luster, and is affected by the humidity in the air. The painting is prone to mold, which makes the painting lose its preservation value. [0003] Existing patent document CN 103483923 A discloses a quick-drying and durable red acrylic pigment, which specifically discloses mixing pigment red 202 with bentonite, mica powder, dispersible latex powder, hydroxypropyl starch ether, methyl acrylate and water Pigment Red 202 is the existing red pigment fi...
