Description

Technical Field

[0001] This utility model relates to the field of waterborne polyurethane coating production technology, specifically a waterborne polyurethane coating heating device. Background Technology

[0002] Waterborne polyurethane topcoat is an important component of anti-corrosion paints in industry. It has good mechanical properties, toughness, impact resistance, good adhesion, flexibility, good anti-permeability and shielding performance, sealing performance, water resistance, salt water resistance, and resistance to media corrosion.

[0003] According to Chinese Patent No. CN209791383U, a heating device for the production of water-based polyurethane resin for automotive coatings includes a material bin, a mixing chamber, and a circulation chamber. The mixing chamber is located at the top of the material bin, and the circulation chamber is located at the bottom. The mixing chamber and the circulation chamber are separated by a welded plate, within which an electric heating block is embedded. A rotating rod is installed in the mixing chamber, with arc-shaped plates welded to both sides. Conical holes are formed on the arc-shaped plates. A large-pore filter plate is installed at one end of the circulation chamber via an mounting block, and a micro-pore filter plate is installed at the other end. A small-pore filter plate is positioned between the large-pore and micro-pore filter plates. A lid is installed on the top of the mixing chamber via a locking mechanism. Insulation cotton is embedded in the inner wall of the material bin. This device improves the flowability of the liquid material during mixing in the mixing and circulation chambers, thereby increasing production efficiency.

[0004] However, the heating device for producing water-based polyurethane resin for automotive coatings proposed in this document is not convenient for cleaning the coating residue on the inner wall of the device during use, which causes different coatings to mix together during subsequent use, affecting the pass rate of coating production.
