Description

Technical Field

[0001] This invention relates to the field of coating technology, and specifically to a Eucommia ulmoides gum-based coating. Background Technology

[0002] The traditional coating materials market suffers from severe fragmentation: interior wall latex paint, exterior wall stone paint, wood PU paint, steel structure epoxy zinc-rich paint… each segment has its own independent technology system, independent supply chain, and independent construction standards. The fundamental reason is that no single film-forming substance can simultaneously meet multiple requirements.

[0003] Eucommia ulmoides' "rubber-plastic duality" has changed this situation. Studies have shown that by controlling the degree of crosslinking, Eucommia ulmoides can continuously transform from a plastic to a rubber. More importantly, Eucommia ulmoides is crystalline at room temperature, and after curing, it forms a dense crystalline layer, naturally possessing a reinforcing effect on the substrate. However, although Eucommia ulmoides has unique rubber-plastic duality, its application potential in the field of coating materials has not yet been systematically explored. Summary of the Invention
