The way to improve the antistatic performance of color paste and plastic masterbatch is mainly based on the dispersing, coupling and lubricating effects of hyperdispersants in plastic systems, as well as the promotion of the effectiveness of antistatic agents.1. Mechanism of action of hyperdispersantsDispersing effect: Hyperdispersants can reduce the interfacial tension of solid particles in liquid or another solid, thereby promoting the uniform dispersion of particles in the medium to form a stable suspension.In plastic masterbatch, hyperdispersants can help antistatic agents to be evenly dispersed in the plastic matrix to prevent them from agglomerating, thereby ensuring that the antistatic agent can fully play its role.Coupling effect: Hyperdispersants have coupling properties and can produce chemical bonds or physical adsorption between the plastic matrix and the antistatic agent, thereby enhancing the interaction between them.This coupling effect helps to firmly fix the antistatic agent in the plastic matrix and improve its durability and stability.Lubricating effect: Hyperdispersants can reduce friction and resistance during plastic processing and improve the processing performance of materials.Through lubrication, the hyperdispersant can reduce the viscosity of the plastic melt, making it easier to flow and form, which is conducive to the uniform distribution of the antistatic agent in the plastic.2. Improvement of antistatic performance of hyperdispersantsPromote the dispersion of antistatic agents: After adding hyperdispersants, the antistatic agent can be more evenly dispersed in the plastic masterbatch, reducing the occurrence of agglomeration.Uniformly dispersed antistatic agents can cover the plastic surface more effectively, improve the conductivity of the plastic, and thus reduce the accumulation of static electricity.Improve the effectiveness of antistatic agents: Due to the coupling effect of hyperdispersants, the interaction between antistatic agents and plastic matrix is enhanced, which helps the antistatic agent to maintain a longer effective period in plastics.At the same time, the lubrication effect of hyperdispersants also helps the antistatic agent maintain a stable dispersion state during the plastic processing process, thereby improving its antistatic performance.3. Application examples and effectsIn practical applications, adding hyperdispersants and antistatic agents to plastic masterbatches can significantly improve the antistatic performance of plastics. For example, in some plastic products, after adding hyperdispersants, their surface resistivity is significantly reduced, and the accumulation of static electricity is effectively suppressed. In addition, the addition of hyperdispersants can also improve the processing performance and mechanical properties of plastics, and improve the quality and stability of products.In summary, color paste and plastic masterbatch can significantly improve the antistatic properties of plastics through its dispersing, coupling and lubricating effects, as well as its promotion of the effectiveness of antistatic agents.
