Scissors handle

Abstract

The invention discloses a scissors handle. The scissors handle is made from a polypropylene modified composite material. The raw material formula of the polypropylene modified composite material comprises the following components in percentage by weight: 60 to 80 percent of copolymerized polypropylene, 10 to 20 percent of calcium carbonate, 2 to 4 percent of antistatic agent, 2 to 4 percent of master batch and 1 to 15 percent of assistant. The scissors handle has the advantages of high impact property, high transparency and the like; the scissors handle can balance scratch resistance, product shrinkage and color difference, and also has excellent performance effects on the aspects of mechanical strength and thermal performance.

Description

technical field [0001] The invention belongs to the field of office supplies, and in particular relates to a handle of scissors. Background technique [0002] Polypropylene is a thermoplastic resin obtained by the polymerization of propylene; it can be divided into three types: isotactic polypropylene, atactic polypropylene and syndiotactic polypropylene according to the position of the methyl group. If the methyl groups are arranged on the same side of the molecular main chain, it is called isotactic polypropylene. If the methyl groups are arranged randomly on both sides of the molecular main chain, it is called atactic polypropylene. When the methyl groups are arranged alternately on both sides of the molecular main chain It is called syndiotactic polypropylene. Polypropylene also includes copolymers of propylene and a small amount of ethylene. It is usually a translucent, colorless solid, odorless and non-toxic. Due to its regular structure and high degree of crystalliza...

Problems solved by technology

However, the PP materials currently on the market and their corresponding modified PP materials more or less always have the following problems: In order to improve a certain aspect of performance, in PP modified materials, when a certain aspect of performance is improved , other properties will be affected, and various factors cannot be well balanced. For example, the shrinkage rate is improved, but the impact resistance and scratch resistance are lost, and the color difference is obvious, and the appearance and texture are poor.

Although it improves the shrinkage problem of the material, the scratch resistance of its products cannot be guaranteed, and the color difference of its products, and for products that focus on appearance and color, there are big problems in their color difference, texture, and bubbles.
