Abstract:
1. A heat radiation shielding component dispersion used to produce heat radiation shielding products, which comprises: fine particles of a hexaboride represented by XB a polymer dispersant in which the fine hexaboride particles are dispersed; said hexaboride being a heat radiation shielding component, and said polymer dispersant being mixed in the fine hexaboride particles in a proportion that the polymer dispersant is from 0.3 part by weight or more to less than 50 parts by weight based on 1 part by weight of the fine hexaboride particles; and does not contain any organic solvent; wherein said polymer dispersant has functional groups adsorbed on the fine hexaboride particles to serve as anchors, as well as polymer backbone chains having an affinity for an organic solvent or thermoplastic resin, and is at least one selected from the group consisting of a polyacrylate dispersant, a polyurethane dispersant, a polyether dispersant, a polyester dispersant and a polyester-urethane dispersant.
