Abstract

The invention discloses a preparation method of water-based acrylate modified emulsion paint. The preparation method is characterized by comprising the following steps: mixing composite nanometer acrylate emulsion, 2 deionized water, titanium dioxide, a short-chain modified CaCO3 / XH-9 nanometer material, ethylene glycol and a triethylhexylphosphoric acid, stirring and dispersing at a high speed for 10min, and uniformly mixing to obtain the water-based acrylate modified emulsion paint.

Description

technical field [0001] The invention relates to a preparation method of a water-resistant acrylate modified emulsion coating. Background technique [0002] Polyacrylate emulsions are widely used in industries such as paints, coatings, adhesives, fabric finishing agents, leather finishing and inks due to their excellent properties. However, most polyacrylate emulsions are ordinary emulsions with large particle sizes, most of which are white opaque low-viscosity colloidal dispersions with a particle size of 0.1-1 μm. [0003] Due to the surface effect, small size effect, quantum size effect and other properties of nanomaterials, nano-polymer particles have high surface energy and low film-forming temperature, and can obtain higher glass transition temperature at the same film-forming temperature. The paint film has better weather resistance and pollution resistance. Generally, the particle diameter of polymer emulsion is larger than 100nm, and microemulsion polymerization, w...
