Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of chemical production, specifically is a kind of polyurethane solid hot melt adhesive safety production equipment. BACKGROUND

[0002] Polyurethane solid hot melt adhesive is hot melt type polyurethane adhesive, which is a special environmentally friendly solventless adhesive. It is solid at room temperature and melts into a viscous liquid when heated to a certain temperature. It returns to solid after cooling and exhibits strong bonding effect. Polyurethane solid hot melt adhesive has high polarity, high strength, good flexibility, excellent heat resistance and other characteristics, as well as high reliability, good chemical and physical uniformity, and simple bonding process.

[0003] The existing safety production equipment is usually used to stir the polyurethane adhesive with stirring blades during use. However, the equipment itself cannot rotate, which limits the flow of materials in the barrel. Although the stirring blades rotate, they cannot fully drive the materials in the entire barrel to mix uniformly. At the same time, the stirring dead angle increases, and some materials may be in a static state for a long time, resulting in uneven mixing. In addition, polyurethane solid hot melt adhesive releases volatile organic compounds such as benzene, toluene, and xylene during heating. These substances can irritate the respiratory tract at high concentrations and cause respiratory diseases. Unfiltered harmful gases are directly discharged into the atmosphere, which pollutes the air and reduces air quality.

[0004] Therefore, it is necessary to provide a new polyurethane solid hot melt adhesive safety production equipment to solve the above technical problems. UTILITY MODEL CONTENTS
