Nanometer-material-base eraser

Abstract

A disclosed nanometer-material-base eraser is composed of the following raw materials in parts by weight: 42-47 parts of modified natural rubber, 7-11 parts of nanometer silicon dioxide, 1-5 parts of nanometer zinc oxide, 1-3 parts ofnanometer titanium dioxide, 1-3 parts of nanometer magnesium oxide, 2-6 parts of glycerol, 2-5 parts of calcium carbonate, and 1-3 parts of a pigment. The nanometer-material-base eraser is soft, and possesses extremely high self lubricating property, reduced friction coefficient with paper, good erasing effect, safety and no pollution.

Description

technical field [0001] The invention belongs to the field of office supplies, and in particular relates to a nano-based eraser. Background technique [0002] At present, there are many types of erasers on the market, some of which are relatively hard, and are easy to tear the paper when used, and the erasing effect is not good; some erasers are manufactured using hydrocarbons, polluting the environment, and nanomaterials are used as a new type of eraser. Materials, there is little research on the application of rubber. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a nano-based rubber. [0004] The technical scheme of the present invention is: a nano-based rubber, which is composed of the following raw materials in parts by weight: 42-47 parts of modified natural rubber, 7-11 parts of nano-silica, 1-5 parts of nano-zinc oxide, and nano-titanium dioxide. 1-3 parts, 1-3 parts of nano magnesium oxide, 2-6 parts of glyc...
