Abstract

The invention is a tri(methyl)epoxy acrylate isocyanurate (TGICA), and its synthesizing metehod: (1) batching ratio: triepoxypropyl isocyanurate (TGIC) to (methyl)crylic acid = 1 : 2.85-3.15 (mol); the dosage of catalyst is 0.4-0.8% (reference toTGIC), that of anti-aggregative agent 0.5-1.5 % (AA, abbreviated for H2-C=CH-COO, or MAA, abbreviated for CH2=C-COO(CH2) ), and that of antioxidant 0.05-0.08% (total material quantity); (2) process course and conditions: casting the AA/MAA, anti-aggregative agent, and catalyst in a reactor, stirring and raising temperatue to 80 deg.C, then casting in TGIC in batches, after TGIC fully dissolves, controlling at 100-110 deg.C and reacting for 1 hour, raising and controlling temperature at 100-120 deg.C to react for 4 hours; stop stirring, sampling at 1 hour intervals to determine until the acid value < 5 mgKOH/g, cooling to under 80 deg.C, and taking out material and packing. The invenrtion is a quickly-curable, excellent-thermal stability and -outdoor weatherability, cost-reducible TGICA and its synthesizing method.

Description

technical field The present invention relates to a novel compound-tri(meth)acrylic acid epoxy ester isocyanurate (TGICA) and its synthesis method. Background technique In recent years, UV-curable coatings (hereinafter referred to as UV coatings) have been widely used in many industrial and civil fields as a kind of green environmental protection coatings because they do not contain volatile organic solvents, and are an important aspect of clean production in the coatings industry. UV coatings are mainly composed of four major parts, namely film-forming resin, diluent monomer, photosensitizer and additives. The performance and application of UV coatings depend entirely on the performance and composition of the above substances. Existing UV film-forming resin acrylic bisphenol A epoxy ester, acrylic polyurethane, its thermal stability and outdoor weather resistance of acrylic polyester are not ideal enough. Contents of the invention The technical problem to be solved by ...
