Embodiment 1

[0034] Mix and heat 0.8 tons of tallow fatty acid and 1.4 tons of stearic acid at 70°C-75°C to a molten fluid state, stir at a speed of 120r / min for 20-30min, and slowly spray 2.2 tons of talcum powder on the molten mixed sample , increase the rotation speed to 150r / min, mix the talc powder and the mixed sample at 70°C-75°C for 30min, add 0.8 tons of polyoxyethylene 12-methyl stearyl ether, and react for 1h. The temperature of the above mixed liquid was raised to 85°C, and then 0.2 tons of polyoxyethylene oleate, 0.05 tons of polyether L61 and 0.2 tons of sodium chloride were added to the mixed sample, stirred and reacted for 30 minutes to obtain a green and environment-friendly mineral deinking agent.

Embodiment 2

[0036] Mix and heat 0.8 tons of tallow fatty acid and 1.2 tons of stearic acid at 70°C-75°C to a molten fluid state, stir at a speed of 120r / min for 20-30min, and slowly spray 2.0 tons of saponite powder on the molten mixed sample , increase the rotation speed to 150r / min, mix the soapstone powder and the mixed sample at 70°C-75°C for 30min, add 1.2 tons of polyoxyethylene 12-methyl stearyl ether, and react for 1h. The temperature of the above mixed liquid was raised to 85°C, and then 0.2 tons of polyoxyethylene oleate, 0.05 tons of polyether L62 and 0.2 tons of sodium sulfate were added to the mixed sample, stirred and fully reacted for 30 minutes to obtain a green and environment-friendly mineral deinking agent.

Embodiment 3

[0038]Mix 0.8 tons of palm oil fatty acid and 1.0 tons of stearic acid at 70°C-75°C and heat it to a molten fluid state, stir at a speed of 120r / min for 20-30min, and slowly spray 1.8 tons of kaolin on the molten mixed sample, lift Rotate to 150r / min, mix the kaolin and the mixed sample at 70°C-75°C for 30min, add 1.6 tons of polyoxyethylene 12-ethyl stearyl ether, and react for 1h. The temperature of the above mixed solution was raised to 85°C, and then 0.2 tons of polyoxyethylene ether oleate, 0.05 tons of polyether L61 and 0.2 tons of sodium chloride were added to the mixed sample, stirred and fully reacted for 30 minutes to obtain a green and environmentally friendly mineral deinking agent.

Abstract

The invention provides a paper-making environmentally-friendly mineral deinking agent. In the conventional anion and non-ion compound deinking agent and mineral material and surfactant compound deinking agent, waste gas and waste water are easy to produce in the production process of the deinking agent; and the product is difficult to biodegrade in the using process under the alkaline deinking condition. The paper-making environmentally-friendly mineral deinking agent comprises the following raw materials in percentage by mass: 5 to 35 percent of anion surfactant, 5 to 25 percent of stearic acid, 10 to 40 percent of silicate inorganic mineral soil, 5 to 20 percent of biodegradable nonionic surfactant, 0.5 to 5 percent of emulsifying agent, 0.01 to 2 percent of polyether type surfactant and 0.5 to 2 percent of inorganic salt electrolyte. By the paper-making environmentally-friendly mineral deinking agent, the effects of removing oily ink, water-based ink and sticky substances by using the deinking agent are improved obviously; the selected components have environmental friendliness and biodegradability and do not have toxicity to a human body and an environment; and secondary pollution is avoided.

Description

technical field [0001] The invention relates to a papermaking auxiliary agent, in particular to a green and environment-friendly mineral deinking agent for papermaking. Background technique [0002] The deinking agents currently used in the market are mainly flotation deinking agents and washing deinking agents. Flotation deinking agent is the most widely used and most effective deinking agent in waste paper deinking production. Flotation deinking agents mainly include anionic fatty acid soap (sodium soap), nonionic fatty alcohols and fatty ethers, complex surfactants, biological enzymes, etc., of which anionic fatty acid soap (sodium soap) and surface active Compound deinking agents have always been the two most important deinking agents used in domestic and foreign markets. [0003] In recent years, the deinking agents developed by the majority of scientific research workers are mainly anionic and nonionic surfactant complexes, biological enzymes, and mineral materials a...
