Smalt for PVC (Poly Vinyl Chloride) plastic processing

The invention provides a smalt for PVC (Poly Vinyl Chloride) plastic processing, consisting of the following components in percentage by weight: 20-45% of carrier, 5-10% of adjuvant, and 50-70% of pigment. The carrier is one or more of chloride-vinyl resin, chloroethylene-vinyl acetate-maleic acid ternary polymerization resin, chloroethylene-vinyl acetate-hydroxy crylic acid ternary polymerization resin, chloroethylene, PVC or methyl methacrylate. According to the invention, the additive is well dispersed, keeps stable chemical stability and is correct and stable in addition amount. In term of a processing technology, as a powdery additive and resin are quite different in the size of particles, uneven addition in amount often happens. However, as the smalt and PVC particles are very similar in diameter, the addition amount can be kept stable. The addition process is convenient. The smalt can keep the environment clean, and is beneficial to production of PVC products with high quality.
