Description

Technical Field

[0001] The present invention relates to the field of chemical materials, in particular to the field of surface treatment agents. Background Art

[0002] In the traditional surface treatment field, scorching treatment agents are often mainly solvent-based. Although this type of treatment agent can provide a good scorching effect, it contains a large amount of organic solvents, which easily volatilize harmful gases during use, endangering human health and polluting the environment. Especially in the process of high-temperature treatment, the volatility problem of solvent-based treatment agents is more prominent. The shortcomings of existing technologies are mainly concentrated in the following aspects: poor environmental protection: solvent-based treatment agents contain a large amount of organic volatiles, which are not friendly to the environment and have safety hazards; complex operation: solvent-based treatment agents require strict operating specifications during use to avoid the release of harmful gases and the risk of explosion; unstable scorching effect: after traditional treatment agents are treated under high temperature conditions, the scorching effect often fluctuates due to uneven solvent evaporation rate, affecting the consistency of product quality.

DETAILED DESCRIPTION

[0038] The purpose of the present invention is to provide a high-performance scorch treatment agent emulsion to effectively improve the stability, processability and performance of the final product of the material. Scorch treatment agents play a vital role in various industrial applications, especially in enhancing the durability and adaptability of materials. The present invention combines the advantages of various monomers and emulsifiers through an innovative process flow, aiming to provide a scorch treatment agent emulsion with excellent performance and environmental friendliness.

[0039] To achieve the above object, the method adopted by the present invention is to add a nonionic emulsifier with excellent emulsification performance to deionized water, then mix a plurality of monomers with the emulsion, and initiate a polymerization reaction to obtain the desired emulsion.

[0040] In the above technical solution, S100 specifically includes:

[0041] S110. Add nonionic emulsifier to deionized water to obtain a uniform emulsion. Nonionic emulsifiers have good biocompatibility and degradability, which is essential for improving the environmental protection characteristics of the emulsion. In addition, nonionic emulsifiers also have good stability and can effectively reduce the surface tension between the liquid phase and the gas phase, preventing the emulsion from stratification and precipitation during storage;

[0042] S120, mixing a plurality of monomers with the emulsion to obtain a first mixed solution. The monomers include acrylic acid, methyl methacrylate, butyl acrylate, etc.;

[0043] S130, initiating a polymerization reaction, dissolving an initiator in water, and adding the first mixed solution to obtain the scorch treatment agent emulsion;

[0044] S140, using a pH regulator to adjust the pH value of the scorch treatment agent emulsion.

[0045] Preferably, S100 specifically includes:

[0046] S110, add 140-150 parts of deionized water to the reactor, start the stirrer, and gradually add 2-3 parts of non-ionic emulsifiers, such as polyethoxylated alkylphenols, alkyl polysaccharides or fatty acid soaps. These emulsifiers not only have good biodegradability, but also provide good stability during the emulsion formation process. Keep the temperature between 40-50°C and continue stirring for 30 minutes to ensure that the emulsifier is completely dissolved and a stable liquid phase is formed, thereby effectively avoiding the occurrence of stratification and precipitation;

[0047] S120, gradually adding 25-30 parts of acrylic acid, 30-35 parts of methyl methacrylate, 35-40 parts of butyl acrylate and 20-25 parts of styrene into the reaction kettle, ensuring continuous stirring during the mixing process to ensure that the monomers are evenly dispersed in the liquid phase to avoid agglomeration;

[0048] S130, when initiating the polymerization reaction, dissolve 0.5-1 part of ammonium persulfate in a small amount of deionized water, and slowly add it to the reactor to start the free radical polymerization reaction. At this time, the reaction temperature needs to be maintained at 80-90°C, and stirring is continued for 2-3 hours until the viscosity of the emulsion increases significantly, indicating that the monomer has been completely polymerized to form an emulsion;

[0049] S140, during the post-treatment and pH adjustment process, use an appropriate amount of pH regulator to adjust the pH value of the emulsion to 7-8 to ensure the stability of the emulsion during storage and use and prevent performance degradation caused by pH changes. This step helps to improve the compatibility of the emulsion and make it show excellent stability in a variety of application environments.

[0050] The reason for adopting the above steps is that through precise reaction conditions and component ratios, the excellent performance of the scorch treatment agent emulsion can be ensured. This emulsion can not only effectively enhance the material's resistance to hydrolysis, but also improve the material's durability and processing performance, thereby adapting to a wider range of application needs. Ultimately, the resulting scorch treatment agent emulsion will have efficient processing performance and good environmental characteristics.

[0051] Considering the poor compatibility of common thickeners with the scorch treatment agent of the present invention and the lack of environmental protection, the present invention provides an efficient thickener for the scorch treatment agent to improve the rheological properties and application effect of the scorch treatment agent. Through reasonable formula design and process steps, the present invention can effectively improve the performance of the thickener.

[0052] In the above technical solution, S200 specifically includes:

[0053] S210, mixing water and bentonite to prepare the inorganic thickener solution;

[0054] S220, mixing water and hydroxyethyl cellulose to prepare the organic thickener solution;

[0055] S230, mixing the inorganic thickener solution and the organic thickener solution, adding a pH regulator, and obtaining the scorch treatment agent thickener.

[0056] The specific steps are as follows:

[0057] S210, take 80-90 parts of water and add them to a stirring tank, and slowly add 5-8 parts of bentonite during stirring. In order to ensure the good dispersion of bentonite, 0.5-2 parts of dispersants (such as sodium hexametaphosphate, sodium pyrophosphate or sodium tripolyphosphate) are added simultaneously, and these dispersants can effectively reduce the mutual attraction between bentonite particles and help them to disperse better. Continue stirring for 30-60 minutes until bentonite is fully dispersed to form a uniform inorganic colloid. At this point, bentonite should be fully hydrated to form a good thickening matrix to enhance the stability and effectiveness of subsequent thickeners.

[0058] S220. In another container, add 25-30 parts of water and heat it to 30-40°C to increase the dissolution rate of hydroxyethyl cellulose. Subsequently, gradually add 2-3 parts of hydroxyethyl cellulose and stir slowly to avoid the formation of lumps. During this process, it is necessary to maintain uniform stirring to ensure that the hydroxyethyl cellulose is completely dissolved in the water. After about 30 minutes of stirring, a viscous transparent solution is finally formed. Since hydroxyethyl cellulose is a heat-sensitive material, excessively high temperatures may cause it to degrade and produce by-products, affecting its thickening properties and the quality of the final product. Within the range of 30-40°C, this thermal degradation phenomenon can be effectively avoided to ensure that its functionality is maintained.

[0059] S230. Mix the dispersed inorganic part with the organic part and continue stirring for 20-30 minutes to ensure that the two parts are evenly combined. During the mixing process, gradually add 0.2-0.5 parts of pH regulator (such as sodium hydroxide, potassium hydroxide, ammonia or citric acid) to adjust the pH value of the system to between 8 and 9. This adjustment helps to enhance the thickening effect of bentonite and stabilize the thickening performance of hydroxyethyl cellulose. The appropriate pH value can improve the rheological properties of the thickener, improve its performance in practical applications, and ensure that the scorch treatment agent has good fluidity and stability.

[0060] Through the above steps, the prepared thickener for scorch treatment agent can not only significantly improve the viscosity and stability of the treatment agent, but also provide better performance support for subsequent industrial applications. This efficient thickener has broad prospects in the application of coatings, inks and other related fields, and can meet the needs of different customers.

[0061] In the above technical solution, S300 specifically includes:

[0062] S300, prepare a mother solution, add 10 parts of deionized water into a stirrer, start stirring, gradually add 80 parts of the emulsion, maintain the stirring speed at 300-500 rpm, and continue stirring for 20-30 minutes.

[0063] In the above technical solution, S400 specifically includes:

[0064] S400, add auxiliary additives, continue stirring, and slowly add 1.5 parts of defoamer (polydimethylsiloxane, polydimethylsiloxane can be used as the defoamer), 2 parts of thickener, 1 part of wetting agent (fatty alcohol polyoxyethylene ether, nonylphenol polyoxyethylene ether) and 0.5 parts of preservative (isothiazolinone preservatives, sodium benzoate, methylisothiazolinone and phenoxyethanol combination) in turn to ensure that each ingredient is fully dispersed.

[0065] Among them, the defoaming agent can use polydimethylsiloxane, alcohol defoaming agent (isomeric alkanol: such as n-pentanol, n-hexanol), fatty acid ester defoaming agent, ethyl hexyl ester, glycerol ester, silicon-based defoaming agent, natural defoaming agent (such as vegetable oil-based defoaming agent, modified starch), surfactant defoaming agent (such as polyether).

[0066] Preferably, polydimethylsiloxane (PDMS) is used mainly because of its excellent defoaming performance and good chemical stability. This defoamer can effectively reduce the surface tension of the liquid, thereby improving the uniformity and effect of the treatment agent. In addition, PDMS has good temperature resistance and wide compatibility.

[0067] The wetting agent may include fatty alcohol polyoxyethylene ether, nonylphenol polyoxyethylene ether, polyvinyl alcohol (PVA), polyether-modified silicone oil, nonionic surfactant (such as hexadecyl alcohol polyoxyethylene ether), fatty acid polyoxyethylene ether and alcohol ether wetting agent.

[0068] Preferably, fatty alcohol polyoxyethylene ether has good biocompatibility and is suitable for water-based formulations. It can effectively reduce the surface tension of the liquid, thereby improving the wettability and dispersibility of the treatment agent. Nonylphenol polyoxyethylene ether has strong wetting and emulsifying ability, which can enhance the contact between the liquid and the substrate and ensure uniform coating. These two wetting agents perform well in a variety of industrial applications and have good compatibility with other ingredients.

[0069] As the preservative, a combination of isothiazolinone preservatives, sodium benzoate, methylisothiazolinone and phenoxyethanol can be used.

[0070] Preferably, the combination of methylisothiazolinone and phenoxyethanol has excellent broad-spectrum antibacterial properties and stability. This combination can effectively inhibit the growth of various bacteria and fungi, thereby improving the shelf life and safety of the treatment agent.

[0071] In the above technical solution, S500 specifically includes:
