Abstract

The invention relates to the technical field of zipper teeth and in particular relates to a transparent flicker polyurethane TPU (Thermoplastic Polyurethane) zipper tooth, a preparation method and a zipper. The TPU zipper tooth comprises the following raw materials: isocyanate, polyhydric alcohols, a chain extender, a cross-linking agent, flicker powder, a lubricant, an antioxidant and an ultraviolet light absorber, wherein the flicker powder comprises a micron-order prism pyramid monomer and a polyacrylamide layer coating the micron-order prism pyramid monomer. As the surface of the micron-order prism pyramid monomer is coated with the polyacrylamide layer, the micron-order prism pyramid monomer has good compatibility and dispersion with a polyurethane prepolymer, and the zipper tooth isendowed with an appearance effect of light flickering and reflection; by additionally adding the cross-linking agent into the formula system, a cross-linking reaction of the polyacrylamide layer and the polyurethane prepolymer is promoted, the micron-order prism pyramid monomer is uniformly dispersed into the polyurethane prepolymer, the TPU zipper tooth of a dense structure is formed, and the zipper tooth has excellent water resistance, tension resistance and toughness.

Description

technical field [0001] The invention relates to the technical field of chain elements, in particular to a transparent flashing polyurethane TPU chain tooth, a preparation method and the chain tooth. Background technique [0002] A zipper is a connecting piece that relies on continuously arranged chain elements to merge or separate items. It is now widely used in clothing, bags, tents, etc. The current mainstream of chain teeth is to use metal materials, such as copper-zinc alloys such as red copper and brass, and copper-zinc-nickel alloys such as zinc white copper. These alloys are shaded through the use of materials in shades of copper, gold, silver. [0003] However, plastic chain teeth cannot be widely used due to the limitation of plastic rigidity, stretchability and other mechanical properties, and the existing plastic chain teeth only have the appearance of filling color, while metal chain teeth , nor does it have a brilliant appearance. Contents of the invention ...
