Background

The problems faced by the water-based paint are that the viscosity of a water-based resin system is low, sagging is easy to occur in the construction process, and the sedimentation phenomenon is easy to occur in the storage process, which are all regulated by a rheological additive to improve the sagging resistance and the storage stability. The polyamide wax which is usually used as a rheological aid is an excellent thixotropic additive, can well balance the anti-sagging and leveling properties of a coating film, can endow a coating system with higher thixotropic performance, has excellent thickening and anti-settling effects, and can effectively prevent pigment and filler in the coating from settling.

Commercial grades of aqueous polyamide wax base stocks are typically obtained by the polycondensation of diacids and diamines. Since the chain structure of the polyamide wax is itself hydrophobic, efficient dispersion in aqueous coatings is difficult. In order to increase the hydrophilicity of the material, a higher acid value is generally imparted to the polyamide wax material, which requires a reduction in the degree of polymerization of the polycondensation reaction at the time of synthesis; the material with low molecular weight and high acid value has excellent hydrophilic performance and is very suitable for being dispersed in an aqueous system. But the molecular weight is low, the crystallization performance is poor, and the crystal form structure is unstable, so that the thermal stability of the crystal form structure in a system is relatively poor. Accordingly, there is a need in the industry for a polyamide wax that has both dispersibility and thermal stability, and coatings comprising the polyamide wax.
