Example Embodiment
[0031] Example 1
[0032] A PMMA ultra-thin hot melt adhesive film composed of 80KG PMMA, 5KG methyl methacrylate-butadiene-styrene terpolymer, 5KG rutile titanium dioxide, and 10KG polyisobutylene rubber raw material components.
[0033] The preparation method is:
[0034] The above-mentioned raw material components are mixed to obtain a mixture; the mixture is added to the mixing chamber of the granulator, the granulator adopts co-rotating parallel twin screws, the screw diameter is 20mm, the screw length to diameter ratio is 32:1, and the granulation temperature is 180℃ , The pellets are made by a pelletizer; the pellets are extruded through a single-screw extruder and calendered by a calender to produce an ultra-thin 0.05mm thick, flexible, foldable, and highly weather-resistant environmentally friendly Type hot melt adhesive film. The drying temperature is 80℃, the drying time is 6h, the screw temperature is 220℃, the conveying section temperature is 230℃, the extrusion pressu...
