Description

Technical Field

[0001] The utility model relates to the technical field of TGIC by-product processing, in particular to a TGIC by-product processing and synthesis device. Background Art

[0002] TGIC is a white granule or powder, a heterocyclic epoxy compound with good heat and weather resistance, adhesion and excellent high temperature performance. Main uses:

[0003] 1. Used as a cross-linking curing agent for pure polyester powder coatings, the dosage is about 7%-9% of the weight of pure polyester (the dosage is determined by the acid value);

[0004] 2. Used as a crosslinking curing agent for carboxyl-containing polyacrylate (PA), the dosage is about 7% of the resin weight (the dosage is determined by the acid value);

[0005] Currently, the TGIC production process produces approximately 10% by-products, amounting to thousands of tons annually. Existing manufacturers generally incinerate these by-products directly, use them as fuel, or bury them. This not only causes certain environmental pollution problems, but also such a large amount of by-products also brings certain economic losses to the enterprises. Therefore, we propose a TGIC by-product processing and synthesis device. Utility Model Content
