Document Type and Number:
WIPO Patent Application WO/2024/067261
Kind Code:
A1
Abstract:
A polyamide molding composition, which comprises the following components: 40-75 parts by weight of PAXC YC resin; 30-60 parts by weight of a white pigment, and an amount of a dispersing agent equivalent to 1.5-5% of the parts by weight of the white pigment. The PAXC YC resin comprises 60-100 mol% XC unit and 0-40 mol% YC unit as calculated on the basis of the molar percentage of PAXC/YC, wherein the XC unit is composed of 1,4-cyclohexanedicarboxylic acid and a diamine unit, and the diamine unit is selected from at least one of a nonane-1,9-diamine unit, a decane-1,10-diamine unit, and a dodecane-1,12-diamine unit; the YC unit is composed of the 1,4-cyclohexanedicarboxylic acid and a diamine unit, and the diamine unit is selected from at least one of aliphatic diamine units containing 5-13 carbon atoms. The white pigment in the polyamide molding composition of the present invention has good dispersity and, where a conventional amount of the white pigment is added, has the advantages of high reflectivity and a high melting point.
