Abstract: A method for manufacturing high heat resistant and high scratch resistant water-based polyurethane, which can improve the mechanical strength and water resistance of water-based polyurethane by using acrylate graft modification, is provided. In particular, 2-hydroxyethyl acrylate (2-HEA), methyl methacrylate (MMA), ethyl acrylate (EA), acrylic acid (AA), glycidyl methacrylate (GMA) and triallyl isocyanuric acid ester (TAIC) are used to dilute polyurethane prepolymer. As a result, the prepolymer has a good dispersing effect, and further, waterborne bridging agent and cellulose nanofiber are added to the water-based polyurethane to obtain water-based polyurethane which has high heat resistance and scratch resistance.

Abstract: An illuminating balloon includes an inflatable envelope and a sectional bulb support integrated in the envelope. The sectional bulb support includes a horizontally freely turnable top support to avoid tangling of the bulb support with the envelope during inflating. The top support defines an upper locking space for connecting the whole bulb support to a radially inward projected ring member integrally provided at a top center of the envelope without causing water leakage thereat. The sectional bulb support is height-adjustable and adaptable to differently sized inflatable envelopes, and has an open bulb-protecting grid that does not block light sources to produce shadows on the envelope, and an air-relieving hole to prevent the envelope from fluttering while being quickly inflated.

Abstract: A multi-purpose massage shaver, with a connecting seat which has a guide slot, and an elastic flange at the center of the connecting seat to hold and latch razor holder, face massager, gums massager, or eye socket bone massager etc. for differing functions.
