Description

Technical Field

[0001] The utility model relates to the technical field of coating production, in particular to a polyurethane coating production filtering device. Background Art

[0002] Polyurethane coatings are a common type of coating, which can be divided into two-component polyurethane coatings and one-component polyurethane coatings. Two-component polyurethane coatings are generally composed of two parts: isocyanate prepolymer and hydroxyl-containing resin, which are usually called curing agent component and main agent component. One-component polyurethane coatings mainly include urethane oil coatings, moisture-curing polyurethane coatings, closed polyurethane coatings and other varieties. Their application is not as wide as two-component coatings. They are mainly used for floor coatings, anti-corrosion coatings, pre-coiled material coatings, etc. Their overall performance is not as comprehensive as two-component coatings. In the production process of polyurethane coatings, in order to avoid the presence of particles and impurities in the coating that affect the painting effect, a filtering device is required for filtering.

[0003] When filtering the polyurethane coating, the existing filtering device will cause the polyurethane coating to pile up for filtering, which reduces the filtering effect of the polyurethane coating and reduces the quality of the polyurethane coating. In addition, when filtering the polyurethane coating, it is easy to cause the filter screen to be blocked, so that the filter screen cannot filter the polyurethane coating well, reducing the filtering speed.
