▎ 摘　　要

NOVELTY - Abrasion-resistant water-based digital printing primer comprises component A and component B in a mass ratio of 10:1. The component A comprises 1-5 pts. wt. modified white carbon and modified graphene, 1-5 pts. wt. emulsifier, 5-10 pts. wt. polyurethane resin, 0.1-0.5 pts. wt. defoamer and 75-90 pts. wt. soft water. The component B comprises 1-5 pts. wt. cross-linked compound, 8-12 pts. wt. curing agent, 69-76 pts. wt. isopropanol and 14-16 pts. wt. soft water. The two components are kept separately, stored at low temperature, protected from light, and sealed during storage. The two components are mixed uniformly during use. USE - Abrasion-resistant water-based digital printing primer. ADVANTAGE - The abrasion-resistant water-based digital printing primer is eco-friendly, and has excellent color fastness, good printing performance and good product adaptability, and improves the abrasion resistance of the primer. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing abrasion-resistant water-based digital printing primer, which involves using modified white carbon and modified graphene, emulsifier, polyurethane resin, defoamer, cross-linked compound, curing agent, isopropanol and soft water.
