specific Embodiment approach 1

[0015] In a specific embodiment of the present invention one, the ink remover paste comprises the following components by weight percentage:

[0016] (1) 25% friction agent, which contains polyvinyl alcohol 10% and silicon dioxide 15%;

[0017] (2) Forming agent 10%, adopts sodium stearate;

[0018] (3) Solvent 45%, adopt water;

[0019] (4) 8% solubilizer, adopt urea;

[0020] (5) Moisturizer 3%, adopt glycerin or sorbitol;

[0021] (6) bleaching agent 8%, adopt sodium hypochlorite;

[0022] (7) 0.5% preservative, using sodium benzoate;

[0023] (8) 0.5% essence.

[0024] Due to the large amount of solvent contained, this embodiment has low solution turbidity and viscosity during production, good fluidity, easy production, and long shelf life of finished products.

specific Embodiment approach 2

[0025] In a second embodiment of the present invention, the ink remover paste comprises the following components by weight percentage:

[0026] (1) Friction agent 65%, which contains polyvinylpyrrolidone 8%, polyvinyl acetate emulsion 25%, calcium carbonate 7%, silicon dioxide 25%;

[0027] (2) Forming agent 8%, adopts calcium stearate;

[0028] (3) 1% solubilizer, adopt thiourea;

[0029] (4) 26% solvent, which contains 18% water and 8% polyethylene glycol.

[0030] Due to less solvents and solubilizers, this embodiment has poor fluidity, high turbidity and viscosity during production, is difficult to produce, and has a short shelf life.

specific Embodiment approach 3

[0031] In a third embodiment of the present invention, the ink remover paste comprises the following components by weight percentage:

[0032] (1) 2% friction agent, using gelatin;

[0033] (2) Forming agent 40%, adopt potassium stearate;

[0034] (3) Solvent 50%, adopt water;

[0035] (4) 3% solubilizer, adopt urea;

[0036] (5) Additive 5%, adopt lanolin hydroxylate.

[0037] Because it contains more molding agents, the curing time is short during production and the fluidity of the solution is poor.

Abstract

An ink erasing paste is prepared from rubbing agent (2-65 Wt%), shaping agent (3-40) and solvent (10-90). Said rubbing agent is the adhesive-type rubbing agent chosen from inorganic adhesive, organic adhesive and their mixture and / or the water-insoluble rubbing agent chosen from aluminium hydroxide, SiO2,calcium pyrophosphate, calcium hydrogen phosphate, calcium carbonate, etc.

Description

Technical field [0001] The present invention relates to an ink remover, specifically an ink remover paste used in conjunction with an eraser or other fiber products. Background technique [0002] When people write, they often make mistakes and need to make corrections. In order to achieve better writing effects, it is usually necessary to eliminate the original handwriting. Common handwriting tools include pencils, pens, ballpoint pens, etc. Pencil writing can be easily erased with an eraser, while pen and ballpoint pen writing cannot be erased. Correction fluid is usually used to cover the writing surface. The use of correction fluid has the following disadvantages: First, the covering layer is not easy to dry after application, and it takes a long time to continue writing on the covering layer, which is extremely inconvenient; secondly, the covering layer of correction fluid is easily rubbed off, so it is difficult to write again. The writing on the covering layer is also...
