摘要:
An aqueous resin composition obtained by emulsion polymerization using a polymerizable unsaturated monomer (b) in the presence of an aqueous resin dispersion (A) comprising an acid-modified polyolefin (a), an ether-based solvent and a basic substance. Also, an aqueous coating composition comprising an aqueous resin dispersion (B) obtained by emulsion polymerization of a polymerizable unsaturated monomer (b) in the presence of an aqueous resin dispersion (A) containing an acid-modified polyolefin (a), an ether-based solvent and a basic substance, with resin beads (C), wherein the content of resin beads (C) is 1-30 parts by mass with respect to 100 parts by mass of the total resin solid content of the coating material. The composition has excellent adhesion for plastic bases and allows formation of coated films with excellent water resistance, stain resistance, damage resistance and solvent resistance.
摘要:
The present invention provides a method for producing paint and a system for producing paint, which enable, in a paint-producing process, moderate stirring and dispersive mixing without causing entrainment of air bubbles, and are also economically advantageous and easier to clean. The system includes a tank 2 for receiving a paint material to be mixed and dispersed, a pump 3 for sucking part of the paint material in the tank 2 and discharging the sucked paint material into the remaining part of the paint material in the tank 2, and a flow path reduction area 5 disposed between the pump 3 and a paint material discharge outlet 4, the discharge outlet 4 being positioned so as to be submerged in the paint material in the tank. This achieves the stirring, mixing, and dispersion.
