What are the performance aspects of polymer silicone additive surface treatment agents?
The difference between polymer silicone additive surface treatment agent and traditional surface treatment agent is shown in:
① The polymer silicone additive surface treatment agent is the introduction of anchoring groups, which ensures its firm adsorption on the surface of solid particles, and many irreversible adsorption, it is difficult to desorption.
② Polymer silicone additive surface treatment agent main chain solvation chain oleophilic group, has a certain compatibility with the resin, to ensure that it forms a certain thickness of the solid particles on the surface of the protective layer, so that the solid particles adsorbed with the surface treatment agent interact due to the van der chemical force, due to the space barrier between the adsorption layer and the particles spring apart each other, Thus solid particles can be stably dispersed in non-aqueous media.
The traditional surface treatment agent is generally random polymer, and its adsorption groups are randomly distributed on the polymer long chain, and the adsorption forms on the surface of solid particles are horizontal, ring and tail. Among the three forms, the horizontal adsorption contributes almost zero to the steric resistance of space, and only the ring and tail adsorption can form an effective space thickness.
Due to the existence of horizontal adsorption, the effective utilization rate of solvation chain is reduced. The anchoring group in the polymer silicone additive surface treatment agent is at the same end of the molecular chain and closely connected, there is not enough distance between each other, and the adsorption form between it and the solid particles is multi-tail, so the effective utilization rate of the solvation chain is greatly improved.
