Abstract

Disclosed is a re-emulsifiable resin powder which is characterized in that the physical properties after being re-emulsified in water are substantially the same as those of the emulsion from which the resin powder is formed. A film formed by using an emulsion obtained by re-emulsifying such a re-emulsifiable resin powder is improved in water resistance. Specifically disclosed is a re-emulsifiable resin powder obtained from an aqueous synthetic resin emulsion which is dispersion-stabilized by a polyvinyl alcohol resin, wherein a hydrophobic monomer having a solubility in water at 20 DEG C of 0.1% or less is contained, as a copolymerizable monomer for constituting the aqueous synthetic resin, in an amount of not less than 30% by weight relative to the total weight of the copolymerizable monomers.

Description

Re-emulsifiable resin powders, aqueous emulsions and adhesive compositions comprising these technical field The invention relates to a re-emulsifiable resin powder obtained by drying an aqueous synthetic resin emulsion. More specifically, the present invention relates to a re-emulsifiable resin powder from which a film formed from an aqueous emulsion is excellent in water resistance, warm water resistance and retort resistance. The re-emulsifiable resin powder can be used in various applications including, inter alia, adhesives for wood parts or wooden materials or for paper and the like, inorganic finishing materials, coatings, and for hydraulic materials such as A mixture of cement and gypsum. Background technique Re-emulsifiable resin powders are prepared by drying (eg, spray drying) aqueous synthetic resin emulsions. Since the re-emulsifiable resin powder is in powder form, it is easier to handle than aqueous synthetic resin emulsions that are mainly packaged in jars...
