Abstract

The invention discloses a rapid packing hot melt adhesive and a preparation method thereof. The hot melt adhesive is used in a high speed sizing machine production line for straws and box sealing in food and beverage industrial packaging. The packing hot melt adhesive can be cured in short time, and has strong adhesive property and better tear resistance, thermal resistance, antioxidation, ageing resistance and ultraviolet resistance; furthermore, the hot melt adhesive product is applicable to wide temperature range, and the preparation method is simple, does not discharge pollutants or dust, does not generate pungent smell, and has good environmental protection performance.

Description

technical field [0001] The invention belongs to the technical field of hot-melt adhesives, and in particular relates to a quick-packing hot-melt adhesive and a preparation method thereof, which are applied to high-speed sizing machine production lines such as straws and box sealers in food and beverage industrial packaging. Background technique [0002] The food and beverage industry packaging production line is initially a slow-speed standard sizing machine, and its sizing speed is 6000~7500 boxes / hour, or 20~30 boxes / minute per minute. In recent years, with the rapid increase in the scale of food and beverage processing enterprises, the continuous improvement of automation, the continuous emergence of new sizing machines and the increase in production demand, the sizing speed of TETRA STROW APPLICATOR 22 / 3 can reach 20,000~24,000 boxes / hour , the sealing machine reaches 30~50 cases / min. The traditional sealing glue is mainly EVA type, and the bonding performance and curin...
