AI Technical Summary
Existing chemical milling protective adhesives release large amounts of volatile organic compounds (VOCs) during the spraying and curing process, polluting the environment and endangering workers' health. They also fail to balance high-temperature spraying fluidity, adhesion to metals, and resistance to peeling after etching.
A solvent-free hot melt spray-type chemical milling protective adhesive is used, which includes thermoplastic polymers, tackifying resins, fillers, antioxidants, defoamers, and γ-aminoethylaminopropyltrimethoxysilane-modified bamboo powder. Through the interlaced composite structure of modified silica and boron nitride, a dense physical barrier layer and chemical cross-linking network are formed, which improves corrosion resistance and adhesion.
It achieves solvent-free emissions, enhances the corrosion resistance and adhesion of the coating, reduces the penetration path of corrosive media, improves the mechanical and chemical stability of the coating, and avoids VOC emissions and safety hazards.
