Polyacrylic emulsion with good binding resistance, water resistance, smoothness and adhesive force and low-temperature film-forming property at same time

Abstract

The invention provides a polyacrylic emulsion with excellent performance. The emulsion particles are fine; the mean grain size is 70-100mm; the emulsion particles have a core-shell structure; and the core and the shell respectively adopt different cross-linking methods. When the mass ratio of core emulsion to core emulsion achieves a proper ratio, the emulsion has water resistance, gliding property, good adhesive force, wettability, permeability, brightness, smoothness and good handle when having the low-temperature film-forming property. A water toy, a craft paint, a water plastic paint, a water-based wood sealer, a water outdoor wood paint and the like can be prepared by the emulsion.

Description

Technical field: [0001] The invention relates to a polymerization method of an acrylic acid microemulsion with a self-crosslinking core-shell structure at normal temperature. technical background: [0002] Acrylic emulsion has excellent physical and chemical properties such as color retention, gloss retention, weather resistance, acid and alkali resistance, pollution resistance and certain hardness. There are a wide variety of raw materials, large options, and relatively cheap prices. Water-based coatings made of acrylates are widely used in construction, leather, paper, clothing, metal anti-corrosion, toys, handicrafts, plastics and other fields. [0003] However, acrylate water-based coatings also have deficiencies in water resistance, solvent resistance, hardness, etc., especially the lack of anti-adhesiveness restricts its application and development. In order to improve the performance of acrylic emulsions, acrylic emulsions are modified. research work. [0004] For ...
