[0067] From the above results, it can be seen that the resin introduced by silica sol 1 has a higher gloss; the resin introduced by silica sol 2 has the best surface dry performance; the introduction of silica sol 1 and silica sol 3 will have an impact on the gloss, but the solid drying and resistance of the resin are significantly improved.

Abstract

The invention belongs to the field of water-based paints, and discloses a high-resistance inorganic-organic composite modified acrylic epoxy ester resin. The high-resistance inorganic-organic composite modified acrylic epoxy ester resin is synthesised from the following raw materials in parts by weight: 30-70 parts of epoxy ester, 5-50 parts of acrylic monomers and 5-25 parts of silica gel, wherein the epoxy ester is prepared by carrying out a catalytic reaction on 40-70 parts of epoxy resin and 20-60 parts of unsaturated fatty acid; the acrylic monomers comprise 20-60 parts of vinyl monomers and 40-70 parts of acrylic acid monomers; the silica gel is prepared by reacting 10-50 parts of an organic silicon intermediate, 5-50 parts of a silane coupling agent, 20-70 parts of a cosolvent, 0.2-5 parts of a pH value regulator and 5-15 parts of water; the nanoscale silica gel is capable of improving the resistance and dryness of a paint film; secondary crosslinking is formed along with the changes of a pH value, thus increasing the crosslinking density after film formation; the structure taking the nanoscale silica gel as a core and the organic resin as a shell is capable of improving the stability of silicon hydroxyl; the water-based epoxy ester resin is capable of reducing a VOC content.

Description

technical field [0001] The invention relates to a preparation method of a highly resistant organic-inorganic composite modified waterborne epoxy acrylate resin, which belongs to the field of waterborne industrial coatings. Background technique [0002] Alkyd resin has the characteristics of dryness, gloss, flexibility, good adhesion, good wetting performance to pigments, excellent construction performance, full coating and excellent decoration. However, its coating film is soft, and its water resistance and alkali resistance are not good. Due to the presence of a large number of ester bonds, the stability of waterborne alkyd resins is often problematic. A large amount of modification techniques have been developed at present, such as a kind of epoxy-modified water-based alkyd resin and its preparation method in patent CN101838389A. Improved adhesion and corrosion resistance, but did not solve the problem of alkyd resin hydrolysis stability; patent CN102391439A introduces s...
