Abstract
The invention provides a short-oil alkyd and a low-smell polyurethane paint containing the same. An adipate long-chain structure is added in resin design, and trifunctional ethanol and tetra-functional ethanol which have different structures are matched so that the stereochemical structure of a resin molecular chain is enhanced, the release property of a product in the filming process is improved, and the odor of a furniture product is greatly reduced. The odor is released within 24h for normally waiting for drying, and thus, low odor is realized.
