Abstract

The invention discloses a surface modifier composite for engineering plastics. The surface modifier composite for engineering plastics comprises one or more components A shown in the structure formula (I) and one or more components B shown in a structure formula (II). In the formulas (I) and (II), R1 and R2 are straight chains or branched hydrocarbons with C1-C45 and n is a natural number. When being applied to crystalline engineering plastics, the surface modifier composite for engineering plastics, provided by the invention, is capable of remarkably improving the polarity of plastics, and therefore the spray coating effect of the plastics can be improved and the plastics are beautiful and durable.

Description

Technical field: [0001] The invention relates to the field of plastic additives, in particular to the application of a surface modifier composition. Background technique: [0002] After the plastic surface is sprayed, it not only has a good appearance, but also has other functions such as oil resistance, water resistance, and humidity resistance, making the plastic durable. However, general plastics, especially easy-to-crystallize plastics such as PP, PA, PBT, POM, etc., are non-polar, have poor surface tension, poor compatibility with most coatings, are not easy to infiltrate, bond and print, and have poor coating performance. The cohesive strength of the coating is low, so some means of increasing its polarity is required to achieve sprayability. [0003] Commonly used methods to increase the polarity of plastics include surface grafting, surface crosslinking, surface coating modification, and blending of polar substances. Among them, the blending method of adding polar ...
