Infrared ray low heating pigment composition and infrared ray low heating material

Abstract

An infrared ray low heating pigment composition comprises at least two pigment components, the pigment components are selected from the group consisting of a red pigment component, a yellow pigment component, a blue pigment component, an orange pigment component, a purple pigment component, a brown pigment component and a white pigment component, and the infrared ray low heating pigment composition can effectively reduce a heating effect due to infrared ray absorption. The invention also provides an infrared ray low heating material including the infrared ray low heating pigment composition and a substrate, the infrared ray low heating material is low in heating effect after absorption of infrared ray, and degree of absorption of heat of the infrared ray low heating material can be effectively reduced.

Description

technical field [0001] The invention relates to a pigment composition, in particular to an infrared low temperature rise pigment composition and an infrared low temperature rise material. Background technique [0002] Generally, vehicle seats are made of plastic materials, such as polyvinyl chloride (PVC), polypropylene (PP), etc., and in order to reduce the degree of dirt and reflection of the seat, easily available and used as pigments are usually added to the plastic. carbon black. Although the use of carbon black can avoid dirt, its disadvantage is that it is easy to absorb infrared rays and cause the seat to heat up quickly. In recent years, as the weather has become hotter and hotter, various products with low temperature rise properties and cool feeling (such as cool clothing, low temperature rise cushions, etc.) raw materials or by adding cool raw materials. Raw materials with low temperature rise properties include pigments or other reagents in addition to the po...
