Problems solved by technology

[0002] Primary and middle school students often need to use correction fluid in their daily studies. The existing correction fluids basically use benzene series and halogenated hydrocarbons as solvents. Because benzene series and halogenated hydrocarbons are highly toxic, long-term use will have adverse effects on students' health. Therefore, there is an urgent need to invent a correction fluid composed of non-toxic materials

Abstract

The invention relates to nontoxic correction fluid which consists of the following raw materials in parts by mass: 50-70 parts of clam meal, 46-63 parts of water, 0.25-0.35 part of sodium hexametaphosphate, 17-23 parts of starch glue, and 0.11-0.15 part of potassium sorbate. The nontoxic correction fluid is prepared according to a certain method. The correction fluid disclosed by the invention is totally composed of nontoxic materials and a small amount of food additives, water is taken as a main solvent, and the correction fluid is high in covering property, uniform in coating and high in rewriting property and does not have any adverse effect to the body in long-term use.

Description

technical field [0001] The invention relates to a non-toxic correction fluid, which belongs to the technical field of stationery. Background technique [0002] Primary and middle school students often need to use correction fluid in their daily studies. The existing correction fluids basically use benzene series and halogenated hydrocarbons as solvents. Because benzene series and halogenated hydrocarbons are highly toxic, long-term use will have adverse effects on students' health. Therefore, there is an urgent need to invent a correction fluid composed of non-toxic materials. Contents of the invention [0003] The purpose of the present invention is to provide a non-toxic correction fluid, which is entirely composed of non-toxic materials and a small amount of food additives, with water as the main solvent, good covering and rewritable properties, and long-term use will not cause any adverse effects on the body. [0004] The non-toxic correction solution of the present i...
