Description

Technical Field

[0001] This invention relates to the field of treatment agents, and more particularly to a water-dispersible fluorine-free copolymer and a treatment agent containing the copolymer. Background Technology

[0002] Polymers are widely used in various products, giving them specific functions. Fluorides, due to their low surface tension, are widely used to impart excellent water and oil repellency to many products. However, fluorinated oil repellents produce perfluorinated and polyfluoroalkyl substances (PFAS) byproducts that are difficult to degrade in the environment. These substances are highly bioaccumulative, toxic, and have long-distance environmental migration capabilities, causing significant impacts on the environment and ecosystem. Wax-based fluorine-free oil repellents are one of the most common types, but they have many limitations in the manufacturing process, including easy clogging during production, easy yellowing of products, generally poor oil repellency, poor stability, and the fact that the processing fluid is weakly acidic, thus also causing some corrosion to equipment.

[0003] Currently, many fields are gradually utilizing novel fluorine-free compounds to replace fluorinated oil-repellent agents. CN113123164A proposes a fluorine-free water and oil repellent agent using edible paraffin wax, stearic acid, gelatin, edible sodium carbonate, carboxymethyl cellulose, and starch as main raw materials, imparting water and oil repellency to food packaging products. CN115058918A proposes a fluorine-free oil repellent agent using acrylic acid, acrylates, and epoxy silane coupling agents as main monomers, thereby imparting oil repellency to pulp molded products. CN115515996A proposes an amide compound modified with long-chain hydrocarbon groups (7-40 carbon atoms) and amide groups on bio-based materials, imparting high-temperature oil resistance to the product. However, the oil repellency performance of these fluorine-free oil repellent agents is not ideal. While existing fluorine-free oil repellent agents with added silicon monomers can improve the oil repellency to some extent, they still suffer from numerous defects such as low product hardness, poor stability of oil repellency, and product sticking to the mold during pulp molding production. Therefore, there is an urgent need to develop new, non-toxic, and environmentally friendly fluorine-free oil repellents that have significant oil-repellent effects and stable oil-repellent performance in order to solve the problems and shortcomings in related oil-repellent fields. Summary of the Invention

[0466] The specific polymerization method of the water-dispersible fluorine-free copolymer of the present invention is described below.

[0467] The polymerization method of the copolymers in this invention is not particularly limited; conventional polymerization methods such as bulk polymerization, solution polymerization, emulsion polymerization, and radiation polymerization can all be used. For example, solution polymerization using organic solvents can generally be chosen to prepare the treatment liquid. This invention preferably uses solution polymerization for preparation.

[0468] In this invention, it is preferable to add a water / acid solution first after polymerization (e.g., solution polymerization), and then remove the organic solvent, thereby dispersing the polymer in water.

[0469] Examples of organic solvents include ketones such as acetone and methyl ethyl ketone; esters such as ethyl acetate and methyl acetate; diols such as propylene glycol, dipropylene glycol monomethyl ether, N-methyl-2-pyrrolidone (NMP), dipropylene glycol, tripropylene glycol, and low molecular weight polyethylene glycol; and alcohols such as ethanol and isopropanol.

[0473] The removal of organic solvents from polymer solutions can be achieved by heating the polymer solution under reduced pressure.

[0474] The preferred initiator for solution polymerization is a peroxide or azo compound with a half-life of 8 hours and a decomposition temperature of 30°C or higher, such as tert-butyl peroxypentanoate, 2,2'-azobis(2-methylpropionitrile), etc.

[0475] The treatment agent of the present invention, which contains a water-dispersible fluorine-free copolymer, can be well added externally to paper substrates or internally to pulp raw materials.

[0476] Paper substrates that are processed can include paper, containers made of paper, and molded objects made of paper (such as pulp molding).

[0477] Paper can be manufactured using existing, well-known papermaking methods. For example, an internal treatment method can be used, in which an oil-resistant treatment agent is added to the pulp before papermaking, or an external treatment method can be used, in which an oil-resistant treatment agent is applied to the paper after papermaking. The treatment method of the treatment agent in this invention is preferably an internal treatment method.

[0478] In the addition, the amount of fluorine-free copolymer contained in the treatment agent is preferably 0.01–4.0 g / m³. 2 Especially 0.1–2.0 g / m 2 The treatment agent is preferably formed from a treatment agent and starch and / or modified starch. The effective solid content for paper use in the treatment agent is preferably 3 g / m². 2 the following.

[0479] In the addition, the amount of the treatment agent is preferably 0.01 to 50 parts by weight or 0.01 to 35 parts by weight relative to 100 parts by weight of the pulp forming the paper, and the treatment agent is mixed with the pulp.

[0480] In the internal treatment of the processing agent, it is preferable to use pulp with a pulp concentration of 1 to 5.0% by weight for papermaking. Additives, including sizing agents, coagulants, reinforcing agents, defoamers, and water-dispersible non-fluorinated copolymers, are added to the pulp. Generally, the pulp is anionic, so it is preferable that at least one of the additives and the non-fluorinated copolymer is cationic or amphoteric, so that the additives and the non-fluorinated copolymer can be well fixed to the paper. It is preferable to use a combination of cationic or amphoteric additives and non-fluorinated copolymers; a combination of anionic additives and cationic or amphoteric non-fluorinated copolymers; or a combination of cationic or amphoteric additives and anionic non-fluorinated copolymers.

[0481] Examples of additives such as sizing agents, coagulants, and reinforcing agents include alkyl vinyl ketone dimers, alkenyl succinic anhydride, styrene polymers, urea-formaldehyde polymers, polyethyleneimine, melamine-formaldehyde polymers, polyamide-epimyl chloride polymers, polyacrylamide polymers, polyamine polymers, polydiallyl dimethyl ammonium chloride, alkylamine-epimyl chloride condensates, alkylene dichlorides and polyalkylene polyamine condensates, dicyanidamide-formaldehyde condensates, dimethyldiallyl ammonium chloride polymers, and olefin / maleic anhydride polymers.

[0482] A typical solution polymerization process for a treatment agent containing a water-dispersible fluorine-free copolymer is as follows:

[0483] In solution polymerization, an organic solvent is added first, followed by the addition of the corresponding monomer for dissolution. Nitrogen gas is then introduced for displacement, an initiator is added, and the temperature is raised to the reaction temperature of 50–120°C. The reaction time is 5–30 hours.

[0484] Specifically, the preparation method (process) of the treatment agent containing the water-dispersible fluorine-free copolymer can be divided into the following steps:

[0485] (1) The monomer, organic solvent and initiator are copolymerized in a reactor to obtain a polymer solution;

[0486] (2) Add an acid solution to the polymer solution for dispersion treatment;

[0487] (3) The polymer solution is desolventized to remove the organic solvent and obtain an aqueous dispersion;

[0488] (4) The amino groups in the aqueous dispersion are converted into nitrogen oxides to obtain a treatment agent containing a water-dispersible fluorine-free copolymer.

[0489] In a preferred embodiment, step (4) involves treating the aqueous dispersion with an aqueous hydrogen peroxide solution to convert the amino group into a nitrogen oxide compound.

[0490] In the treatment agent, the concentration of the fluorine-free copolymer can be 0.01 to 50% by weight, for example 0.1 to 40% by weight, preferably 1 to 30% by weight, more preferably 5 to 25% by weight.

[0491] In the preparation of the treatment agent, the preferred copolymerization method for the fluorine-free copolymer is solution polymerization.

[0492] In this invention, the workpiece is treated with a treatment agent comprising a water-dispersible fluorine-free copolymer. "Treatment" means applying the treatment agent to the workpiece through impregnation, spraying, coating, or internal addition. Through treatment, the fluorine-free copolymer, as the active ingredient of the treatment agent, penetrates into the interior of the workpiece and / or adheres to the surface of the workpiece or becomes part of the workpiece.

[0493] Example

[0494] Unless otherwise specified, the terms used in this specification have the general meanings known to those skilled in the art; “%” means “weight %”; “parts” means “parts by weight”.

[0495] The following are the processing and testing methods for paper products:

[0496] Paper product processing

[0497] Processable paper products include thin paper, thick paper, linerboard, or molded pulp, etc., from a unit area (m²) 2 A paper box weighing 500 grams, or per unit area (m²) 2 Kraft paper weighing 100 grams, from a unit area (m²) 2 ) reaching 150 grams of thin paper, to a unit area (m²) 2 Paper-plastic products weighing up to 300 grams can be processed. The raw materials for paper products can be chemically bleached pulp or unbleached pulp, wood pulp, chemimechanical pulp, mechanical pulp, etc.

[0498] Specific methods for handling paper lunch boxes

[0499] The pulping process was carried out directly with bleached sugarcane pulp / bleached bamboo pulp (3:7), with a Shore freeness of 23°SR and a pulp concentration of 0.3%. A pre-synthesized treatment agent was added at a rate of 8% by weight of the oven-dry pulp. A standard paper lunch box weighing 15 grams was produced using a small-scale pulping and forming system.

[0500] Oil resistance test (paper lunch box)

[0501] Place the sample on a dry glass or plate lined with filter paper, fill it with edible oil (salad oil, peanut oil, rapeseed oil) at the specified temperature*, let it stand for 30 minutes, observe whether the sample is deformed, and observe whether there are oil stains on the filter paper. Give it a rating according to the following standards. The higher the rating, the better the oil resistance.

[0502] *Specified temperatures for edible oils: heat resistance oil test (100±5℃), cold resistance oil test (0~5℃);

[0503] Level 4: Impermeable on both the inner wall and the back.

[0504] Level 3: Discoloration of the inner wall, no penetration on the back.

[0505] Level 2: Backside penetration rate > 5%

[0506] Grade 1: 5% ≤ back permeability < 20%, and the sample is not deformed and the filter paper underneath has no obvious oil stains.

[0507] Grade 0: Backside permeability ≥ 20%

[0508] Water resistance test (paper lunch box)

[0509] Place the sample on a dry glass or plate lined with filter paper, fill it with water at 95±5℃, and let it stand for 30 minutes. Observe the sample for any deformation, seepage, or leakage at the bottom. If the sample does not show any deformation, seepage, or leakage, it is considered to have "passed"; if deformation, seepage, or leakage occurs, it is considered to have "failed".

[0510] During the test, water vapor condensation at the bottom of the sample caused by the temperature difference between the inside and outside of the sample is not considered as seepage or leakage.

[0511] Relative yellowing (whiteness) rating of lunch boxes

[0512] Samples with and without the pre-synthesized treatment agent were prepared under the same process conditions. The sample without the pre-synthesized treatment agent was used as a standard. The relative yellowing (whiteness) change of the sample with the pre-synthesized treatment agent and the standard were visually evaluated. The samples were rated according to the following criteria.

[0513] Grade 0: Visually noticeably whiter compared to the standard product.

[0514] Level 1: Visually visibly whiter compared to the standard product.

[0515] Level 2: Visually, the whiteness is basically similar to that of the standard product.

[0516] Level 3: Visibly yellowed compared to the standard product.

[0517] Level 4: Visually noticeably yellowed compared to the standard product.

[0518] Food container hardness evaluation

[0519] Samples with and without the pre-synthesized treatment agent were prepared under the same process conditions. The sample without the treatment agent was used as a standard. The hardness changes of the sample with the pre-synthesized treatment agent and the standard were visually evaluated. Ratings were assigned according to the following standards.

[0520] Grade 0: Significantly softer than standard products

[0521] Grade 1: Slightly softer than standard products

[0522] Grade 2: Hardness is basically similar to the standard product.

[0523] Grade 3: Slightly harder than the standard product

[0524] Level 4: Significantly harder than the standard product

[0525] Evaluation of anti-sticking performance

[0526] Twenty standard lunch boxes weighing 15 grams each were produced continuously using a small-scale pulping and molding system. The bottom of the mold was observed for any sticking. If no sticking occurred after producing 20 standard lunch boxes weighing 15 grams each, the result was marked as "passed". If sticking occurred, the result was marked as "failed".
