Problems solved by technology

[0002] In the process of waste paper being recycled and remade, according to the process requirements, the ink on the surface of the waste paper needs to be cleaned. In the prior art, biocatalysts are usually used to separate cellulose from ink particles by hydrolysis catalytic reaction. However, The disadvantage is that the ink particles and cellulose have opposite charges and have a strong electrostatic attraction. Although the biocatalyst separates the ink particles and cellulose, the time is relatively short, and the ink particles and cellulose will be in the Recombination takes place within a certain period of time, resulting in extremely low efficiency of subsequent extraction of ink particles

Embodiment 1

[0013] A deinking separator with various combination systems, including anionic surfactant, nonionic surfactant and amphoteric surfactant.

[0014] The anionic surfactants include the following substances: sodium salts, ammonium salts, amine salts, amino alkoxides, magnesium salts, alkyl sulfates, alkyl ether sulfates, alkyl amido ether sulfates, alkylaryl Polyether Sulfate, Glycerin Monosulfate, Alkyl Sulfonate, Alkyl Phosphate, Alkylamide Sulfonate, Alkylaryl Sulfonate, Alpha Olefin Sulfonate, Paraffin Sulfonate, Alkyl sulfosuccinates, alkyl ether sulfosuccinates, alkylamide sulfosuccinates, alkyl sulfosuccinates, acyl sarcosinates, and acyl glutamates.

[0015] The nonionic surfactant is composed of one or more of the following substances: acrylamide, methacrylamide, N-methacrylamide, N,N-dimethyl (meth)acrylamide, N-isopropyl(meth)acrylamide, N-(2-hydroxypropyl)methacrylamide, N-isopropyl(meth)acrylamide, N-methylolacrylamide, N-vinyl Formamide, N-vinylacetamide, N-vinyl...

Embodiment 2

[0024] All the other are the same as Example 1, the difference is that the anionic surfactant includes methacrylic acid and acrylic acid, the nonionic surfactant is composed of polyacrylate and vinyl acetate, and the amphoteric surfactant The agent comprises alkyl amphoteric monoacetate and alkyl amphoteric diacetate, wherein, the mass ratio of the anionic surfactant to the nonionic surfactant is 1.1.

Abstract

The invention discloses a deinking separating agent with multiple combined systems. The deinking separating agent comprises an anionic surfactant, a nonionic surfactant and an ampholytic surfactant, wherein the anionic surfactant comprises sodium salt, ammonium salt, amine salt, alkamine salt and magnesium salt, the nonionic surfactant comprises methacrylamide, and the ampholytic surfactant is selected from C10-C24 alkyl acylamino C3-C8 alkyl glycine betaine, sulpho glycocoll betaine and the like. The separating agent can effectively inhibit ink particles from rebinding with the cellulose after separation, thus improving the deinking efficiency.

Description

technical field [0001] The invention relates to the technical field of waste paper ink treatment, in particular to a separating agent with multiple combination systems. Background technique [0002] In the process of waste paper being recycled and remade, according to the process requirements, the ink on the surface of the waste paper needs to be cleaned. In the prior art, biocatalysts are usually used to separate cellulose from ink particles by hydrolysis catalytic reaction. However, The disadvantage is that the ink particles and cellulose have opposite charges and have a strong electrostatic attraction. Although the biocatalyst separates the ink particles and cellulose, the time is relatively short, and the ink particles and cellulose will be in the Recombination takes place within a certain period of time, resulting in extremely inefficient subsequent extraction of ink particles. Contents of the invention [0003] In order to solve the above-mentioned technical problem...
