Plastic hair pin

Abstract

The invention discloses a plastic hair pin and in particular relates to a plastic hair pin opened or closed by the elasticity of a plastic body. The plastic hair pin consists of a base and a cover base, wherein one end of each of the base and the cover base is an opening end; the other end of each of the base and the cover base is a pivot end; and hairlines can be released and clamped by opening and closing the opening end by the elasticity of the plastic hair pin. The plastic hair pin comprises the following components in percentage by weight: 50 to 60 percent of cyclohexanedimethanol (CHDM), 25 to 35 percent of glycol, 5 to 15 percent of pure terephthalic acid (PTA), 1 to 5 percent of whitening agent and 2 to 10 percent of K glue or polypropylene (PP). The plastic hair pin has extensibility, plasticity, toughness, bright white appearance and environmentally-friendly characteristic.

Description

technical field [0001] The present invention relates to a plastic hair clip, in particular to a plastic hair clip that is opened and closed by the elasticity of the plastic body. The plastic hair clip is mainly composed of 55% CHDM (1,4-cyclohexanedimethanol), Ethylene glycol (Ethylene Glycol, EG) 30%, PTA (pure terephthalic acid) 10%, whitening agent (Optical Brightener) 1%, and selected from PP (Polypropylene) or K glue (K-Resin) 4 % composed of. Background technique [0002] General hairdressing mainly uses hair clips, hair hoops, hairpins or other appliances suitable for shaping and bundling hair. [0003] Since the hair clip is in the hair, the clip body must have considerable bending resistance, so most operators will focus on metal springs, etc. The selection of this material is mainly due to the use of better rigidity and resilience. Metal, but because the clip body made of this kind of metal pays attention to the aesthetics, it is often necessary to paste various ...

AI Technical Summary

Problems solved by technology

[0003] Since the hair clip is in the hair, the clip body must have considerable bending resistance, so most operators will focus on metal springs, etc. The selection of this material is mainly due to the use of better rigidity and resilience. Metal, but because of the aesthetics of the clip body made of this metal, it is often necessary to paste various plastic decorative sheets on the metal to increase its color, texture and texture.

[0004] Due to the high fluctuation of international raw materials, the production cost of metal has increased significantly. When the metal with the plastic decorative sheet is discarded and not used, it is not easy to separate and recycle the metal alone, and the metal must often be retrieved by solvents, combustion, etc. Therefore, the aforementioned Plastic decorations are prone to environmental hazards such as toxicity, and such metal clips, due to the complicated manufacturing process of plastic decorative sheets, and the metal parts are prone to rust, especially when they are often in contact with watery environments such as bathing, often Moisture is attached and it is easy to get wet and the chance of deeper rust

[0005] In the prior art of plastic materials, although some operators try to use a single plastic raw material such as ABS resin (acrylonitrile-styrene-butadiene copolymer), polycarbonate (Polycarbonate, PC for short) or use acrylic (polyacrylic) Polymethylmethacrylate), but this kind of material cannot have ductility, plasticity and toughness at the same time, so it is prone to breakage, whitening, aging and other phenomena
