Description

Technical Field

[0001] The present invention relates to the technical field of antistatic agents, and in particular to a polymerizable eutectic antistatic agent, a preparation method thereof, and application thereof in decorative paper. Background Art

[0002] A polymerizable deep eutectic solvent-based antistatic agent is a new type of antistatic agent. It is a low-melting-point mixed solvent composed of two or more substances mixed in a specific ratio. It exhibits excellent properties such as low melting point, high ionic conductivity, environmental friendliness, non-toxicity, non-volatility, non-flammability, and low cost. The ionic substances in this antistatic agent can adsorb dust particles in the air, forming charged particles. The non-ionic substances neutralize these charges, preventing charge accumulation and ensuring safety and production efficiency.

[0003] Polymerizable deep eutectic solvent-based antistatic agents are widely used in a variety of fields, including polymer materials, electronic devices, packaging materials, and device materials. In the polymer materials field, adding antistatic agents to polymers such as polycarbonate, polyoxymethylene, polyamide, and polybutylene terephthalate effectively reduces surface resistivity, enabling rapid dissipation of static charges and preventing problems caused by static accumulation, such as dust collection, electric shock, and spark discharges. In electronic device manufacturing, antistatic agents prevent static damage to sensitive components, ensuring proper operation. In the packaging industry, antistatic agents reduce static accumulation in packaging materials during transportation and storage, preventing damage to goods. In the decoration industry, wood flooring and wall panels are currently one of the most popular decorative materials among consumers. The surface finishing / coating materials commonly used for wood flooring and wall panels are primarily paint or melamine-impregnated paper. Therefore, to achieve antistatic properties on wood flooring and wall panels, the paint or melamine-impregnated paper must be treated with an antistatic agent. This is primarily achieved by adding a suitable antistatic agent. However, most of the antistatic agents in the existing general technology have the problem that the antistatic performance is not long-lasting and is easily ineffective. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention provides a polymerizable eutectic antistatic agent, a preparation method thereof, and application thereof in decorative paper.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: The present application discloses a polymerizable eutectic antistatic agent, which comprises the following raw materials in parts by weight: 20-30 parts of polyurethane, 30-40 parts of polyaniline, 15-25 parts of n-butanol, 1-3 parts of catalyst, 12-16 parts of diethanolamine, 24-30 parts of graphite, 15-25 parts of polycarbonate, 20-40 parts of modified epoxy resin, 18-28 parts of glycerol, 15-25 parts of acetone, 8-14 parts of curing agent, 15-25 parts of sodium hydroxide solution, 10-20 parts of diethyl carbonate and 18-26 parts of bisphenol A.

[0006] Preferably, the antistatic agent comprises the following raw materials in parts by weight: 25 parts of polyurethane, 35 parts of polyaniline, 20 parts of n-butanol, 2 parts of catalyst, 14 parts of diethanolamine, 27 parts of graphite, 20 parts of polycarbonate, 30 parts of modified epoxy resin, 23 parts of glycerol, 20 parts of acetone, 11 parts of curing agent, 20 parts of sodium hydroxide solution, 15 parts of diethyl carbonate and 22 parts of bisphenol A.

[0007] By setting up the above technical scheme, both the polyaniline molecules and the modified epoxy resin have a certain rigidity. Under the action of the curing agent, the epoxy group of the modified epoxy resin opens to generate an ether homopolymer, and the cross-linked network structure formed between the molecules is strengthened, the hardness of the oil film is improved, and it is beneficial to extend the service life of the antistatic agent.

[0008] Preferably, the catalyst is selected from one of dibutyltin dilaurate, zinc isooctanoate, bismuth isooctanoate or dibutyltin diacetate.

[0009] Preferably, the curing agent is one of trifluoroacetic acid, isocyanate or triethylenetetramine.

[0010] Preferably, graphite and sodium hydroxide solution are weighed in proportion, wherein the concentration of the sodium hydroxide solution is 1 mol / L, 1 / 2 of the total mass of graphite is pretreated, and the other half is not treated. The pretreatment steps of the graphite are as follows: Under magnetic stirring conditions at 32° C., the graphite is impregnated with a sodium hydroxide solution for 30-40 minutes, and then filtered, washed, and vacuum-dried in sequence to obtain pretreated graphite.

[0011] By setting up the above technical solution, graphite and polycarbonate are incompatible with each other, and the mixing of the two is prone to agglomeration, resulting in poor dispersion effect. The pretreated graphite treated with sodium hydroxide solution under magnetic stirring conditions is easily fully dispersed in the polycarbonate, which promotes the blending effect with the polycarbonate. After being used to prepare an antistatic agent and sprayed on the surface of the product, static charge can be conducted and released in these channels, thereby effectively preventing the accumulation and discharge of static electricity and fully improving the antistatic properties of the product.

[0012] Preferably, the antistatic agent comprises the following raw materials in parts by weight: 25 parts of silver powder.

[0013] By setting up the above technical solution, after mixing the silver powder, the modified epoxy resin reduces the distance between the silver powder particles, forming more effective conductive channels, thereby improving the conductive performance, so that the final antistatic agent product has good antistatic properties after spraying to form an oil film.

[0014] Preferably, the preparation steps of the modified epoxy resin are as follows: weighing 10 parts of isosorbide, 50 parts of polytetramethylene glycol, 10 parts of epoxy resin and 2 parts of polyphosphoric acid, adding polytetramethylene glycol and polyphosphoric acid into a three-necked flask, reacting at 75° C. for 3 hours, washing with deionized water 3 times, then adding isosorbide and epoxy resin, stirring and reacting at 75° C. for 3 hours, and cooling to obtain the modified epoxy resin.

[0015] By setting up the above technical solution, the modified epoxy resin and graphite can be fully dispersed, the mixing effect with the system is improved, and the antistatic properties of the antistatic agent are fully exerted.

[0016] The present application also discloses a method for preparing a polymerizable eutectic antistatic agent, comprising the following steps: S1. Weigh polyurethane, 1 / 2 of the total weight of polyaniline, n-butanol, catalyst and diethanolamine in proportion, disperse them uniformly by ultrasonication, and set aside; S2. Weigh polycarbonate and pretreated graphite in proportion, dry them in vacuum at 85° C. for 5 h, mix them evenly, melt-blend them using a screw extruder, and granulate them for later use; S3. Weigh the modified epoxy resin, 1 / 2 of the total weight of polyaniline, glycerol, acetone, and curing agent in proportion, and ultrasonically disperse them uniformly. Then, add untreated graphite, diethyl carbonate, bisphenol A, silver powder, the mixture obtained in step S1, and the mixture obtained in step S2. Stir at a mechanical speed of 800-900 r / min for 30-40 minutes at 75° C., let it stand for 2 hours, and then transfer it to a planetary gravity mixer. The speed is gradually increased from static to 1800 r / min for degassing treatment to obtain a solvent-based polymerizable low eutectic antistatic agent.

[0017] Preferably, in step S2, the extrusion conditions of the screw extruder are: screw speed: 180-200 r / min, screw temperature: 200-220° C., die melt pressure: 45-50 MPa, and reaction time: 2.5-3.5 min.

[0018] The present application also discloses an application of a polymerizable low eutectic antistatic agent in decorative paper. Before use, the solvent-based polymerizable low eutectic antistatic agent is shaken well and evenly sprayed on the outer surface of the decorative paper.

[0019] The beneficial effects of the present invention are: During the ultrasonic dispersion process of polyurethane with polyaniline, n-butanol, catalyst and diethanolamine, the hydrogen atoms on the NH bonds in polyaniline form a cross-linked network structure with the polyurethane, which increases the interaction between the polyaniline and the polyurethane matrix. After the polyaniline particles are uniformly dispersed in the polyurethane matrix, this uniform structure gives the composite material good antistatic uniformity, thereby improving the antistatic effect and structural stability of the antistatic agent product.

[0020] Both polyaniline molecules and modified epoxy resins have a certain rigidity. Under the action of the curing agent, the epoxy groups of the modified epoxy resin are opened to generate ether homopolymers. The cross-linked network structure formed between molecules is strengthened, and the hardness of the oil film is improved, which is beneficial to extend the service life of the antistatic agent.

[0021] The pretreated graphite can be better mixed with polycarbonate and fully dispersed to form a conductive network. When used to prepare antistatic agents and sprayed on the product surface, static charges can be conducted and released in these channels, effectively preventing the accumulation and discharge of static electricity and fully improving the antistatic properties of the product.

[0022] Polytetramethylene glycol reacts with polyphosphoric acid to form polytetramethylene glycol phosphate, which then reacts with epoxy resin to graft polyether groups onto the epoxy resin backbone. The resulting cured modified resin exhibits tough fracture characteristics, effectively enhancing the toughness of the epoxy resin. The introduction of reactive functional groups such as carboxyl and hydroxyl groups into the polytetramethylene glycol-modified epoxy resin increases the curing shrinkage of the modified resin. When mixed with silver powder, the spacing between silver powder particles is reduced, creating more effective conductive pathways and improving electrical conductivity. This results in the final antistatic agent product exhibiting excellent antistatic properties after spraying to form an oil film. DETAILED DESCRIPTION

[0056] Examples 1-3 of the present invention primarily involve changes in the content of each component, altered parameters during the preparation steps, and altered types of catalyst and curing agent. These changes have minimal impact on the resistivity of the antistatic agent film. Comparative Example 4 shows that the absence of a catalyst has little effect on the antistatic agent film. This is likely because the catalyst only accelerates the reaction, slightly improving product quality and thus having little impact on the product's antistatic properties.

[0057] Comparative Examples 3 and 11 show that the absence of n-butanol and silver powder has a certain impact on the antistatic properties of the product, indicating that silver powder may have a certain promoting or coordinating effect on the modified epoxy resin, which is beneficial to improving the antistatic properties of the product. Furthermore, Comparative Examples 1, 2, and 4 show that polyurethane, polyaniline, n-butanol, and the catalyst may indeed interact with each other and form a cross-linked network structure, which has a significant effect on improving the antistatic properties of the corresponding product.

[0058] Comparative Example 5 shows that not adding graphite does have a significant impact on the antistatic properties of the product. Comparative Examples 6 and 7 show that not pretreating the graphite or using ordinary epoxy resin instead of modified epoxy resin also significantly affects the antistatic properties of the product. Therefore, pretreating the graphite and modifying the epoxy resin are very necessary.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
