Water-based pressure-sensitive adhesive production device and production process thereof

Abstract

The water-based pressure-sensitive adhesive production device comprises a main frame, a positioning groove is formed in the front side of the top end of the main frame, a sliding groove is formed in the top end of the middle of the front side of the main frame in the vertical direction, a limiting rod is arranged in an inner cavity of the sliding groove, and the upper end and the lower end of the limiting rod are arranged on the upper side and the lower side of the inner cavity of the sliding groove correspondingly; a lifting mechanism is arranged at the top end of the main frame, an emulsifying mechanism is arranged at the bottom end of the lifting mechanism, an emulsifying box is placed in an inner cavity of a positioning groove, a rotating groove is formed in the bottom end of an inner cavity of the emulsifying box in the circumferential direction, rolling grooves are formed in the bottom end of an inner cavity of the rotating groove at equal intervals in the circumferential direction, and rolling balls are arranged in inner cavities of the rolling grooves in a rolling mode. A smashing ring is arranged in the middle of the bottom end of an inner cavity of the emulsifying box, and extrusion grooves communicating with the inner cavity of the smashing ring are formed in the outer wall of the smashing ring in the circumferential direction at equal intervals. When the device is used, the emulsifying effect can be enhanced, the emulsifying time is shortened, and the device is convenient to use.

Description

technical field [0001] The invention relates to the technical field of water-based pressure-sensitive adhesives, in particular to a water-based pressure-sensitive adhesive production device and a production process thereof. Background technique [0002] Pressure-sensitive adhesive, short for pressure-sensitive adhesive, is a type of adhesive that is sensitive to pressure. It is mainly used to prepare pressure-sensitive tapes. Pressure-sensitive adhesives can be divided into two types: rubber type and resin type according to the main resin components. Adhesive can also be divided into water-based and solvent-based pressure-sensitive adhesives according to different dispersion media, and can be divided into packaging, protection, insulation, warning, labeling, stationery and other products according to different uses; [0003] Water-based pressure-sensitive adhesives and their products are widely used, and the most common form is to coat them on paper, stretched polypropylene,...

AI Technical Summary

Problems solved by technology

[0005] The emulsifier cuts, disperses, and impacts the material through the high-speed rotation of the homogenizing head connected to the engine, so that the material becomes more delicate and promotes the blending of oil and water. However, when the traditional emulsifier is used, the emulsification The effect is poor, and the effect of complete emulsification cannot be achieved, because the density of some materials is slightly higher than that of water, such as acrylic acid and methacrylic acid, which will cause the material with a density greater than water to sink to the bottom of the water, and when rotating emulsification, the floating on the water surface The material will follow the vortex generated by the rotation into the emulsification head for crushing and emulsification, and the material that sinks into the bottom of the water will have a centrifugal force greater than the centripetal force due to its own density, causing it to rotate against the inner wall of the emulsification tank, and due to the vortex The rotation speed of the surrounding water is much lower than the rotation speed of the vortex center, which leads to insufficient impact force between the material sunk into the bottom and the inner wall of the emulsification tank, thereby reducing the emulsification effect and increasing the emulsification time. If an emulsification tank with a smaller inner diameter is used, it will greatly Lower production efficiency to a certain extent, not easy to use
