Embodiment 1

[0032] Environmentally friendly deinking agent raw materials (parts by weight): 6 parts of sodium silicate, 16 parts of talcum powder, 15 parts of sodium sulfate, 30 parts of sodium bicarbonate, 7 parts of glycerin, 8 parts of surfactant, and 8 parts of penetrant.

[0033] Described tensio-active agent is mixed by ethylene glycol monostearate, triethylene glycol monostearate, diethylene glycol monostearate, and described ethylene glycol monostearate The mass ratio of ester, triethylene glycol monostearate and diethylene glycol monostearate is 1:1:1.

[0034] The penetrating agent is formed by mixing dibutyl ether, isopentyl ether and di-tert-butyl ether, and the mass ratio of dibutyl ether, isopentyl ether and di-tert-butyl ether is 1:1:1. The preparation method of the environmental protection deinking agent: the stirring speed is 300 rpm, first add sodium silicate; then add talcum powder, stir for 5 minutes; then add sodium sulfate, stir for 5 minutes; then add sodium bicarbo...

Embodiment 2

[0036] The environment-friendly deinking agent is prepared by the raw material ratio and method of Example 1, the difference is only: the surfactant is mixed from ethylene glycol monostearate and triethylene glycol monostearate , the mass ratio of the ethylene glycol monostearate and triethylene glycol monostearate is 1:1. Promptly get the environment-friendly deinking agent of embodiment 2.

Embodiment 3

[0038] Prepare environment-friendly deinking agent by the raw material ratio of embodiment 1 and method, difference is only: described tensio-active agent is mixed by ethylene glycol monostearate, diethylene glycol monostearate, so The mass ratio of ethylene glycol monostearate and diethylene glycol monostearate is 1:1. Promptly get the environment-friendly deinking agent of embodiment 3.

Abstract

The invention discloses an environment-friendly deinking agent. The environment-friendly deinking agent is prepared from the raw materials in parts by weight: 2 to 8 parts of sodium silicate, 12 to 18 parts of talcum powder, 10 to 20 parts of sodium sulfate, 20 to 40 parts of sodium bicarbonate, 4 to 8 parts of glycerol, 5 to 10 parts of surfactant and 5 to 10 parts of penetrant. According to the environment-friendly deinking agent disclosed by the invention, by reasonably selecting the surfactant and the penetrant to compound, the deinking performance of the environment-friendly deinking agent is effectively increased; the environment-friendly deinking agent is a green and environment-friendly type waste paper environment-friendly deinking agent which is suitable for a waste paper deinking technology through a washing method, the environment-friendly deinking agent can be adopted by chemical pulping or non-chemical pulping waste paper, and the waste paper is as white as new paper after deinking; the environment-friendly deinking agent does not contain toxic and harmful substances and is beneficial for environment protection.

Description

technical field [0001] The invention relates to a deinking agent and a preparation method thereof, in particular to an environment-friendly deinking agent and a preparation method thereof. Background technique [0002] In recent years, due to the increasing public awareness of environmental protection and the increasing shortage of paper-making raw materials, the utilization of waste paper has received widespread attention worldwide, and its usage has increased year by year. Waste paper recycling has the advantages of saving virgin fibers, reducing environmental pollution, simplifying process flow, and reducing energy consumption. It has good economic and social benefits, and is a national economy and people's livelihood issue that is directly related to environmental governance and resource protection. my country is a developing country with a serious shortage of forest resources and a shortage of grass resources. It will be more important to make full use of waste paper ra...
