Abstract

The invention discloses a plastic pencil holder material which comprises the following raw materials in parts by weight: 0.1-0.4 part of octyl mercaptan tin, 130-150 parts of polystyrene, 50-70 partsof talcum powder modified rubber powder and 3-7 parts of ethylene-bis-stearamide. Effective compatibility of talcum powder with waste rubber powder is achieved, furthermore the dispersion performanceof the talcum powder modified rubber powder in polystyrene is improved, and the mechanical stability of a finished product material is improved.

Description

technical field [0001] The invention belongs to the field of materials, in particular to a plastic pencil holder material. Background technique [0002] Traditional pencil shafts are mainly made of wood, but this method has high requirements for wood. Only limited species of wood such as red cedar, xiangshan, sida, basswood and kai wood can be used, which seriously restricts its use. It is used for development and does not meet the current requirements for environmental protection. Based on this, those skilled in the art have proposed to replace the original wood pencil holder with a plastic pen holder, but the existing plastic pencil holder, adding various inorganic fillers to the plastic particles, is likely to cause defects such as poor mechanical stability and easy breakage of the pencil holder. Contents of the invention [0003] The purpose of the present invention is to solve the problem that a large amount of wood is used in the existing pencils, resulting in waste...
