AI Technical Summary

Technical Problem

The preparation of existing quick-drying polyolefin hot melt adhesives suffers from problems such as inaccurate premixing measurement, dust pollution, lack of unified central control linkage between modules, and difficulty in meeting the segmented melting requirements of the reactor design. These problems result in uneven melting, low dehydration efficiency, easy failure or uneven dispersion of added components, reduced product toughness, and poor batch consistency.

Method used

The preparation device, which adopts an integrated central control system, includes a premixing module, a main material conveying module, a reaction synthesis module, and a liquid phase metering and addition system. Through precise metering, coordinated control, and segmented processing, combined with segmented heating and stirring rate curves and a vacuum system, it ensures that the additives are added in the optimal state, thereby achieving uniform mixing and efficient dehydration of the materials.

Benefits of technology

It improves product consistency, quality and production efficiency, solves problems such as metering deviation, dust pollution, independent operation of modules and poor vacuum effect in traditional equipment, ensures product uniformity and toughness, and improves the level of production automation.
