Facile strategy to protect material surface using peelable film from prevulcanized rubber latex.

This study introduces a method for producing environmentally friendly peelable film using prevulcanized rubber latex, offering a simple and cost-effective solution capable of covering complex shapes. The synthesis investigation explores the relationship between conventional rubber formulations and the film's performance, highlighting the significance of selecting appropriate chemicals to improve functionality. Key considerations for selecting the latex compound formulation include the solution's properties, particularly focussing on flow behaviour and coating time, as well as the mechanical properties, fire resistance, peel ability and durability of the resulting film under challenging conditions. The primary investigation into the impact of the zinc diethyldithiocarbamate : sulphur (ZDEC : S) ratio on crosslink density provides insight into rheological and mechanical properties. Furthermore, the addition of phenol, 4-methyl-, reaction products with dicyclopentadiene and isobutene (CPL) as an antioxidant improves heat resistance and oxygen tolerance. The remarkable versatility of peelable film allows for its application through various methods, including sagging (1–10 s–1), painting and spraying (10–100 s–1), effectively protecting against dust, scratches and temperatures exceeding 200°C. Particularly noteworthy are its low peel force of 0.139 N, 44 mm removal path and 2-month service life. The findings from testing the crucial properties of the manufactured films, which meets industrial standards, indicate a pathway to produce environmentally sustainable products, with a strong potential for further advancement towards commercial production.
