Description

Technical Field

[0001] The utility model relates to the technical field of hot melt adhesive production, in particular to a high-efficiency cooling mechanism for hot melt adhesive production. Background Art

[0002] The basic resin of hot melt adhesive is copolymerized ethylene and vinyl acetate under high temperature and high pressure, that is, EVA resin. This resin is the main component for making hot melt adhesive. The proportion and quality of the basic resin determine the basic properties of the hot melt adhesive. Generally, VA content of 18-33 and melt index of 6-800 are selected. The lower the VA content, the higher the crystallinity and the greater the hardness. Under the same conditions, the larger the VA content, the lower the crystallinity and the greater the elasticity. The selection of EVA melt index is also very important. The smaller the melt index, the worse the fluidity, the greater the strength, the higher the melting temperature, and the poor wetting and permeability of the adherend. On the contrary, if the melt index is too large, the melting temperature of the adhesive is low, the fluidity is better but the bonding strength is reduced. The selection of its additives should be appropriate for the ratio of ethylene to vinyl acetate.

[0003] At present, during the production of existing hot melt adhesives, the hot melt adhesives are often cooled by air cooling. However, this method requires the hot melt adhesives to be cooled in batches through different equipment. This method not only increases the use and occupied area of ​​the equipment, but also reduces the overall cooling time of the hot melt adhesive by batch cooling, increases work intensity and reduces work efficiency. Therefore, we propose an efficient cooling mechanism for hot melt adhesive production. Utility Model Content
