Abstract

The invention provides a pencil handwriting eliminating liquid which is characterized in that the formula comprises materials in parts by weight as follows: 10-30 parts of ethoxy ethyl acetate, 5-10 parts of dihydroxyethyl amine ether acetic ester and 40-50 parts of triethylene glycol methyl ether acetic ester. The preparation process comprises the steps as follows: the ethoxy ethyl acetate, the dihydroxyethyl amine ether acetic ester and the triethylene glycol methyl ether acetic ester are mixed uniformly, so that the product is obtained. The pencil handwriting eliminating liquid has the advantages that the raw materials are easy to obtain, the cost is low, the liquid is environment-friendly and free from peculiar odor, and the paper surface is not damaged when the handwriting is eliminated.

Description

technical field [0001] The invention belongs to a stationery, in particular to a stationery product for removing ink. Background technique [0002] At present, there are common classifications of Xiaoziling in the market. Carbon Eliminator, Multifunctional Eliminator, Good Partner Eliminator. Carbon is mainly some carbon handwriting, like the printed handwriting in life. The multifunctional ones are those ballpoint ones. A good partner is the ink of the carbon ballpoint pen of the printer, the ink of the carbon paper. Several chemical components in Xiaoziling are covered with strong alkali, corroded, and bleached. These types will affect things other than him, as well as humans and animals. I have used other similar products before, and it is not very easy to operate, and after using it at that time, the paper will become thinner and the color of the shading of the paper will change. After a period of time, the used paper will deteriorate and break when touched up. The...
