example 1

[0026] In parts by mass, agent A includes: bleaching powder, 100 parts by mass, with an effective content of 50%; ethylene-propylene rubber, 10 parts by mass; and toluene, 30 parts by mass. In parts by mass, agent B included: acetone, 100 parts by mass; furfural, 4 parts by mass; and ethylene glycol-methyl ether, 0.5 parts by mass.

[0027] Prepare agent A and agent B; apply the prepared agent A on the font of the waste paper with a roller brush; after one minute, apply the prepared agent B to the part that has been coated with agent A with a roller brush After another minute, use an electric blower to blow hot air to the paper to remove the font ink and all substances of agent A and agent B from the paper. Finally, it was found by visual inspection that no ink marks were present on the obtained recycled paper.

example 2

[0029] In parts by mass, agent A includes: bleaching powder, 100 parts by mass, with an effective content of 60%; ethylene-propylene rubber, 20 parts by mass; and toluene, 40 parts by mass. In parts by mass, agent B included: acetone, 100 parts by mass; furfural, 5 parts by mass; and ethylene glycol-methyl ether, 1 part by mass.

[0030] Prepare agent A and agent B; apply the prepared agent A on the font of the waste paper with a roller brush; after one minute, apply the prepared agent B to the part that has been coated with agent A with a roller brush After another minute, use an electric blower to blow hot air to the paper to remove the font ink and all substances of agent A and agent B from the paper. Finally, it was found by visual inspection that no ink marks were present on the obtained recycled paper.

example 3

[0032] In parts by mass, agent A includes: bleaching powder, 100 parts by mass, with an effective content of 70%; ethylene-propylene rubber, 30 parts by mass; and toluene, 50 parts by mass. In parts by mass, agent B included: acetone, 100 parts by mass; furfural, 6 parts by mass; and ethylene glycol-methyl ether, 1.5 parts by mass.

[0033] Prepare agent A and agent B; apply the prepared agent A on the font of the waste paper with a roller brush; after one minute, apply the prepared agent B to the part that has been coated with agent A with a roller brush After another minute, use an electric blower to blow hot air to the paper to remove the font ink and all substances of agent A and agent B from the paper. Finally, it was found by visual inspection that no ink marks were present on the obtained recycled paper.

[0034] The waste paper can be various waste papers, such as waste printing paper, waste copy paper, waste fax paper, etc., and the paper size is not limited. The de...

Abstract

The invention provides a deinking agent composition. The composition comprises an A agent and a B agent in parts by weight, wherein the A agent comprises the following components in parts by weight: 100 parts of bleaching powder with effective content between 50 and 70 percent, 10 to 30 parts of ethylene propylene rubber, 30 to 50 parts of toluene; and the B agent comprises the following components in parts by weight: 100 parts of acetone, 4 to 6 parts of furfural, and 0.5 to 1.5 parts of ethylene glycol-monomethylether. According to the deinking agent composition provided by the invention, carbon powder ink, pencil ink and the like on waste paper can be completely removed so as to obtain recycled new paper. Therefore, the deinking agent composition is advantageous to environmental protection and treatment and utilization of special confidential data, the office cost is reduced, and low-carbon economical development is promoted.

Description

technical field [0001] The present invention relates to a deinking agent composition. Background technique [0002] In recent years, with the increasing attention to environmental issues, the use of disposable consumables has gradually developed to recyclable items. [0003] In daily office work, a large amount of printing, copying, faxing and other paper needs to be used, and the paper (single-sided or double-sided) that is no longer used after printing (referred to as waste paper here) is usually destroyed by a shredder or manually. , or for materials that have nothing to do with confidential information, they are sent to waste recycling stations through various channels to be used as raw materials for papermaking. [0004] Whether it is by shredders or manual destruction of waste paper, or used as a raw material for papermaking, there are significant costs involved, while running counter to the existing low-carbon economy. [0005] In addition, the current processing of...
