Description

Technical Field

[0001] The utility model relates to the technical field of environmentally friendly coating mixing, and more specifically to a high-boiling aromatic hydrocarbon solvent mixing device for polyurethane environmentally friendly coating. Background Art

[0002] Polyurethane environmentally friendly coating is an environmentally friendly coating, and its main component is polyurethane resin. Compared with traditional coatings, polyurethane environmentally friendly coatings have the advantages of low volatile organic compound (VOC) emissions, excellent weather resistance and chemical resistance, and are widely used in construction, automobiles, ships and other fields. High-boiling point aromatic solvents are a commonly used organic solvent with high boiling point and low volatility. In polyurethane environmentally friendly coatings, high-boiling point aromatic solvents are usually used as diluents, regulators or co-solvents to improve the rheological properties, drying speed and film properties of the coating.

[0003] Polyurethane environmentally friendly coating high boiling aromatic solvent mixing equipment is a kind of equipment used for mixing and preparing polyurethane environmentally friendly coating. It is mainly used to mix, stir and heat the raw materials such as polyurethane resin, environmentally friendly coating components and high boiling aromatic solvents to prepare environmentally friendly coating products that meet the requirements. Polyurethane environmentally friendly coating high boiling aromatic solvent mixing equipment usually includes a feed hopper, a mixing barrel, a stirring device and a control system.

[0004] The existing high-boiling aromatic solvent mixing equipment for polyurethane environmentally friendly coatings still has the following problems: the existing mixing equipment needs to use a heating device to heat the materials when mixing the raw materials, so as to reduce the viscosity of the raw materials and promote the mixing reaction between the raw materials. However, when the raw materials are mixed and heated, the heating effect of the existing mixing equipment is not uniform, and the raw materials close to the center are difficult to be heated well, so a lot of time is needed to stir the raw materials, which undoubtedly reduces the uniformity of heating and the efficiency of mixing. Secondly, the stirring devices of the existing mixing equipment are mostly stirred horizontally, which makes it difficult for the raw materials accumulated at the bottom to be mixed with the raw materials at the top, which will also increase the mixing time, causing many inconveniences to the use;

[0005] Secondly, when putting raw materials into existing mixing equipment, the raw materials are often directly filled into the feed hopper and then dropped into the mixing barrel. However, the raw materials are often piled up on one side of the mixing barrel, and the various raw materials cannot be better evenly distributed, which undoubtedly affects the time required for mixing, resulting in uneven mixing and low mixing efficiency, causing great trouble to the user.

[0006] In view of this, we propose a high-boiling aromatic solvent mixing equipment for polyurethane environmentally friendly coatings. Utility Model Content

[0007] Technical issues to be solved
