Problems solved by technology

However, these three production methods are difficult to form mass production due to large investment and high cost, or due to many disadvantages such as poor weather resistance and adhesion, fear of collision, and scratch resistance.
Moreover, the profiles produced by these three methods all have a common defect during assembly: because the color is limited to the surface, corner-clearing marks with color difference will inevitably appear after welding and corner-clearing, which affects the overall aesthetic effect
Although the tinting ability and tinting strength are the nature of the pigment and have nothing to do with the PVC formula, the heat stability, light stability, sulfide spot, fading and dispersibility of the pigment may be affected by other components in the production formula

Abstract

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.

Description

technical field [0001] The invention relates to a high-concentration and high-efficiency pigment preparation colored sand. That is to say, the special processing technology is used to uniformly and stably disperse the pigment in the carrier resin with a high concentration, and then it is used for the coloring and processing of polyvinyl chloride plastic. Background technique [0002] With the promotion and popularization of PVC plastic door and window products, people have put forward higher and more requirements for it-in addition to more choices in performance, they also hope to break through the traditional white color and give users a better life experience in terms of color. More options to suit different architectural environments and different consumer groups. [0003] At present, there are generally three ways to produce colored profiles in China: co-extrusion, film coating and spraying. However, these three production methods are difficult to form mass production ...
