Description

Technical Field

[0001] The present application relates to the technical field of container chassis anti-corrosion, and in particular to a container chassis anti-insect water-based asphalt paint and a processing technology thereof. Background Art

[0002] As a special tool for international transportation and logistics, containers travel between land and sea and are subjected to the erosion of severe weather. Therefore, the physical and chemical performance requirements of container protective films have strict high-performance requirements for corrosion resistance and weather resistance.

[0003] At present, the coatings widely used for container protection are mainly asphalt anti-corrosion coatings. Traditional asphalt anti-corrosion coatings are mainly solvent-based asphalt coatings. Although they can provide good corrosion resistance and wear resistance, they will produce large amounts of volatile organic compounds (VOCs) during construction. VOCs not only cause secondary environmental pollution, but also seriously endanger the health of construction workers, bringing them a high risk of occupational diseases, which is no longer in line with the current trend of green and low-carbon development. To this end, the inventor provides a water-based asphalt paint for anti-insect pests of container chassis and its processing technology. Summary of the invention

[0004] In order to solve the problem that a large amount of volatile organic compounds (VOCs) are generated during the construction of traditional solvent-based asphalt anti-corrosion coatings, causing secondary pollution to the environment and endangering the health of construction workers, the present invention provides a container chassis anti-insect water-based asphalt paint and a processing technology thereof.

[0005] During the actual development process, we learned from downstream ocean shipping companies about the pest problems encountered in long-distance container transportation, mainly involving refrigerated goods and other containers that may inadvertently transport pests. Given that there are 250-280 million containers in the world used to transport industrial products such as food, clothing, and mining, it is inevitable that containers are inadvertently mixed with pests. Container pests will not only damage the goods, especially causing serious health and safety risks to cold chain food, but also the mixed pests will spread diseases, cause collective public health and safety problems, or cause biological invasion problems, and seriously damage the ecosystem. Pests such as cockroaches and borers will not only damage the goods, but also may carry a variety of pathogens, posing a threat to human health; such as jewel beetles, longhorn beetles, termites, etc. will also cause serious damage to the goods and even affect the balance of the entire ecosystem.

[0006] The present invention provides a container chassis anti-insect water-based asphalt paint which not only solves the volatile organic compounds (VOC) of traditional asphalt anti-corrosion coatings, but also solves the container chassis insect pest problem, thereby improving the safety performance of container ocean shipping.

[0007] A container chassis anti-insect water-based asphalt paint is achieved through the following technical solutions:

[0008] A container chassis anti-insect water-based asphalt paint is prepared from 100 parts by weight of a water-based asphalt paint base material A and 8-20 parts by weight of an activator material B; the water-based asphalt paint base material A is prepared from 100 parts by weight of a water-based asphalt emulsion with a solid content of 25-50wt%, 40-60 parts by weight of a water-based polyurethane latex with a solid content of 35-50wt%, 40-60 parts by weight of a water-based epoxy resin latex with a solid content of 35-50wt%, and 15-30 parts by weight of a filler. The invention discloses a novel novel nanostructured carbon foam composition, 4-8 parts by weight of an insecticide composition, 0.5-2 parts by weight of an anticorrosive synergist, 0.5-2 parts by weight of an antirust synergist, 0.5-2 parts by weight of an antifungal and antibacterial agent, 1-4 parts by weight of a thickener, 1-4 parts by weight of a wetting and dispersing agent, 1-3 parts by weight of a defoaming agent, 0.5-1 parts by weight of a pH value regulator, 0.5-5 parts by weight of a film-forming aid, 0.5-1 parts by weight of an anti-settling agent, and 0.10-0.25 parts by weight of a drying agent.

[0009] Preferably, the polyurethane latex particles in the waterborne polyurethane latex are isocyanate terminated, with an R value of 1.40-1.50, and the polyol used to synthesize the waterborne polyurethane latex includes terminal hydroxyl polybutadiene and / or dihydroxy-terminated vinyl silicone oil in combination with at least one of polyester diol, polyether diol, and polycarbonate diol.

[0010] Preferably, the water-based epoxy resin latex contains at least bisphenol A epoxy resin.

[0011] Preferably, the activator material B is made of 65-85 parts by mass of epoxy resin curing agent, 10-25 parts by mass of polyurethane chain extender, and 5-10 parts by mass of double bond polymerization initiator.

[0012] The container chassis insect-proof water-based asphalt paint prepared in the present invention is a water-based formula system with ultra-low VOC volatility, which solves the organic volatile matter VOC pollution problem of traditional asphalt anti-corrosion coatings, and the insect-proof composition in the formula is effectively anchored in the internal cross-linked network structure of the cured asphalt paint film and the surface of the cured asphalt paint film, which can play a long-term insect-proof role, solve the problem of pest pollution encountered in the container chassis ocean shipping, and can ensure the hygienic safety performance of the goods carried in the container and the hygienic safety of the operation during the loading and unloading of the container.

[0013] The addition of water-based epoxy resin, on the one hand, enhances the overall viscosity strength, and on the other hand, forms a stable three-dimensional network structure system in the asphalt paint film, which can improve the density of the asphalt paint film and thus improve its overall weather resistance, corrosion resistance, wear resistance, and impact stability.

[0014] On the one hand, the addition of water-based polyurethane latex improves the brittleness caused by the three-dimensional network structure system formed by epoxy resin, increases the flexibility and deformation resistance of the asphalt paint film, and the glass transition temperature of the polyurethane structure is low, which gives the asphalt paint film good low-temperature flexibility, effectively improves the overall temperature resistance, and broadens the application scope of water-based asphalt paint for container chassis pest control; on the other hand, the polyurethane latex particles contain double bonds. In the subsequent construction-curing process, double bond polymerization reaction occurs under the action of the double bond polymerization initiator in the activator material B, which can improve the overall cross-linking density and density of the asphalt paint film, and improve the overall wear resistance, impact resistance, and corrosion resistance of the asphalt paint film. In addition, the three-dimensional network formed by the polyurethane latex particles can also play a damping and shock-absorbing effect, which can improve the safety of container installation and unloading operations.

[0015] Preferably, the mass ratio of the dry weight of asphalt in the aqueous asphalt emulsion to the dry weight of polyurethane latex particles in the aqueous polyurethane latex and the dry weight of epoxy latex particles in the aqueous epoxy resin latex is 100:(20-30):(20-30).

[0016] By adopting the above technical scheme, it can be ensured that the cured asphalt paint film has excellent weather resistance, corrosion resistance, rust resistance, and wear resistance, while also having a good slow-release insect repellent composition effect, achieving a long-lasting insect repellent effect.

[0017] Preferably, the waterborne polyurethane latex is made of isocyanate, polyol, chain extender, catalyst, emulsifier and deionized water, and the ratio of the NCO molar amount in isocyanate to the total NCO molar amount of hydroxyl groups in polyol and chain extender is 1.40-1.50.

[0023] Preferably, the method for preparing the waterborne polyurethane latex comprises the following steps:

[0024] S1. At a stirring speed of 150-300 rpm, add accurately measured isocyanate, polyol, and catalyst to the reactor, adjust the system temperature to 85-90 ° C, and stir the reaction at 150-300 rpm for 2-3h;

[0025] The reactor is equipped with an acetone condensation reflux device and a pressure relief device;

[0026] S2. Add chain extender and acetone, and react at 80-90℃ for 3-4h until the viscosity is 8*10 3 *5*10 4 mPa·s, add acetone into the reactor to control the viscosity at 3000-4000mPa·s;

[0027] S3. When the temperature drops to 40-45°C, dimethylethanolamine is added to neutralize and adjust the pH value to neutral, and then deionized water and emulsifier are added, and high-speed shear emulsification treatment is performed. Finally, acetone is removed by distillation to obtain the target product - water-based polyurethane latex.

[0028] The preparation method of the water-based polyurethane latex used in the present invention is relatively simple, which is convenient for industrial batch production, reduces the use cost of the water-based polyurethane latex, and further reduces the total production cost of water-based asphalt paint. In addition, the prepared water-based polyurethane latex contains double bonds. During the later construction-curing process, on the one hand, the insect-proof composition can be grafted to the inside and surface of the asphalt paint by double bond polymerization, and the insect-proof composition is not easy to fall off and become ineffective, thus achieving a long-term insect-proof effect; on the other hand, the cross-linking density of the asphalt paint film can be improved, thereby improving the overall wear resistance, impact resistance and corrosion resistance of the asphalt paint film.

[0030] Preferably, the preparation method of the fluorine-silicon modified bisphenol A epoxy resin is as follows: 1.01-1.05 mol of γ-methacryloxypropyltrimethoxysilane, 1 mol of pentafluorophenyl methacrylate, and 300-400 mL of xylene are added to a four-necked beaker equipped with a thermometer, a stirring device, a reflux condenser, and a dropping funnel, heated to 80-85° C. and then kept warm for 10 minutes, and an appropriate amount of AIBN is added to the reaction system through the dropping funnel every 30 minutes, and the reaction temperature is kept at 80-85° C. The reaction was maintained at 85° C. and nitrogen protection for 2.0 h, and the mixture was cooled to below 30° C. to obtain a fluorosilicone intermediate; 50 parts by mass of the fluorosilicone intermediate was mixed evenly with 300-350 parts by mass of bisphenol A epoxy resin, 200-300 mL of toluene, and 150-200 mL of butanone, and then 0.8-1.2 parts by mass of DMP-30 catalyst was added, and the mixture was heated to 105-108° C., and the ring-opening reaction was carried out for 30-40 min, and the mixture was naturally cooled to room temperature to obtain a fluorosilicone-modified bisphenol A epoxy resin.

[0031] The fluorosilicone-modified bisphenol A epoxy resin contained in the water-based epoxy resin latex can greatly improve the weather resistance and corrosion resistance of the cured asphalt paint film. By optimizing the addition amount of fluorosilicone-modified bisphenol A epoxy resin, a container chassis insect-proof water-based asphalt paint with high bonding strength, excellent weather resistance and corrosion resistance can be prepared, thereby improving the product's market competitiveness.

[0032] Preferably, the epoxy resin curing agent is composed of anhydride curing agent, tertiary amine auxiliary curing agent, and triglycidyl isocyanurate.

[0033] Preferably, the acid anhydride curing agent is at least one of hexafluorodianhydride, 4,4'-thiodiphthalic anhydride, 4,4'-phenylenedioxydiphthalic anhydride, and 4,4'-biphenyl ether dianhydride.

[0034] Preferably, the tertiary amine auxiliary curing agent is at least one of benzyl dimethylamine, o-hydroxybenzyl dimethylamine, 2,4,6-tris(dimethylaminomethyl)phenol, 2-methylimidazole, and 2-phenylimidazole.

[0035] Preferably, the polyurethane chain extender is composed of at least one of 4-(hexafluoro-2-hydroxyisopropyl)aniline and 2,2-bis(4-aminocyclohexyl)hexafluoropropane and at least one of 1,4-butanediol, 1,5-pentanediol and 1,6-hexanediol.

[0036] Preferably, the double bond polymerization initiator is at least one of benzoyl peroxide, dicumyl peroxide, potassium persulfate, ammonium persulfate, and dimethyl azobisisobutyrate.

[0037] By adopting the above technical solution, the weather resistance and corrosion resistance of the asphalt paint film formed by curing can be improved.

[0038] Preferably, the filler composition is composed of at least one of silicon micropowder, calcium carbonate, talc, kaolin, titanium dioxide, barium sulfate, calcined shell powder and at least one of flake graphite, molybdenum disulfide and mica powder.

[0039] Preferably, the anti-corrosion synergist is at least one of nano-scale nano zirconium oxide, nano titanium carbide powder, nano zirconium carbide, nano zirconium nitride powder, nano titanium nitride, and nano aluminum nitride.

[0041] The inorganic components in the filler composition, anti-corrosion synergist and anti-rust synergist have relatively poor compatibility with the asphalt system, while the composite emulsion system formed by water-based asphalt, water-based polyurethane and water-based epoxy resin is both hydrophilic and lipophilic compatible. Therefore, it is necessary to carry out surface modification treatment with aminosilane or methyl methacrylic silane so that the inorganic components in the filler composition, anti-corrosion synergist and anti-rust synergist can be more evenly dispersed in the composite emulsion liquid to ensure the weather resistance, corrosion resistance, wear resistance, rust resistance, antibacterial and mildew resistance of the prepared cured-asphalt paint film.

[0042] Rust-proofing agents can prevent the initial corrosion of metals and prevent flash rust on the metal surface. The use of calcium carbonate and gypsum powder can neutralize the acidic substances in the paint film through calcium ion exchange, inhibiting corrosion. Calcium ions can also combine with metal oxide films to form a protective layer, which protects the steel base material of the container, reduces corrosion, and prolongs its service life.

[0043] Preferably, the antibacterial and mildew-proof agent is an isothiazolinone complex and / or a single-atom antibacterial and mildew-proof agent.

[0044] Antibacterial and mildew-proof agents give the asphalt paint film excellent antibacterial and mildew-proof properties, effectively resist the erosion of effective microorganisms, and improve the antibacterial and mildew-proof properties and sanitary safety performance of the asphalt paint film.

[0045] Preferably, the isothiazolinone complex is at least one of 4,5-dichloro-N-octyl-4-isothiazolin-3-one, methylisothiazolinone and benzisothiazolinone.

[0046] Preferably, the insect repellent composition is a porous adsorbent and an insect repellent agent adsorbed on the surface and pores of the porous adsorbent; the surface of the porous adsorbent includes at least one of zeolite, mesoporous nano-silica, aerogel powder, porous alumina, microporous glass powder, porous ceramic powder, activated carbon powder, and halloysite powder; the insect repellent agent is at least one of malathion monocarboxylic acid, cypermethrin, permethrin, and flumethrin in combination with at least one of garlic extract, citronella extract, camphor leaf extract, wormwood extract, sophora flavescens extract, cnidium monnieri extract, quisqualis evodia extract, thunder ball extract, neem extract, onion extract, ginger extract, and tobacco extract.

[0047] The pest-proof composition can play a good pest-proof effect and has little impact on external environmental pollution and human health. It has the effect of slow-release of pest-proof agents, so that the asphalt paint film has a relatively long-lasting pest-proof effect. The active residues such as -OH carried by the porous adsorbent itself can, on the one hand, physically adsorb the pest-proof agent in its own pores, and on the other hand, chemically adsorb the pest-proof agent on its own pores and surface, thereby playing a good role in pest-proofing. The adsorption amount of the porous adsorbent can be regulated, such as performing low-temperature plasma activation treatment on the porous adsorbent, so that the surface and pores of the porous adsorbent have more active residue groups such as -OH, -COOH, -NH2, -SH, etc. The porous adsorbent is connected to the asphalt paint film as follows: the active residue groups of the porous adsorbent and the hydrogen bonds between the polyurethane molecular chains make the porous adsorbent distributed on both sides of the polyurethane molecular chains; and the porous adsorbent treated with surface aminosilane reacts with the epoxy resin and is grafted into the three-dimensional cross-linked network structure formed by the epoxy resin, so that the porous adsorbent is evenly distributed inside and on the surface of the asphalt paint film; and the porous adsorbent treated with surface methyl methacryl silane reacts with the double bonds in the polyurethane molecular chain under the action of the double bond polymerization initiator and is grafted onto one side of the polyurethane molecular chain, so that the porous adsorbent is evenly distributed inside and on the surface of the asphalt paint film, giving the formed asphalt paint film a lasting anti-disease and pest control effect.

[0048] Preferably, the thickener is at least one of TEGO ViscoPlus 3000 polyurethane thickener, TEGO ViscoPlus3010 polyurethane thickener, BASF Rheovis PU 1291, BASF Rheovis PU 1331, and BASF RheovisAS1130.

[0049] The above thickeners can improve the shear viscosity of the coating and give the water-based asphalt paint good anti-sagging performance. Polyurethane thickeners contain both hydrophilic and hydrophobic groups on their molecular chains, which thicken in the water phase and associate with the polymer emulsion for thickening.

[0050] Preferably, the wetting and dispersing agent is at least one of BASF Dispex Ultra PA 4570, BASF Dispex Ultra PA4590, BASF Dispex Ultra PX 4575, Dispex Ultra PX 4585, TEGO Dispers 750W, and TEGO Dispers 755W.

[0051] The above-mentioned wetting and dispersing agents can reduce the surface tension of the system, enhance the wetting of the coating on the substrate, and thus help improve the adhesion and bonding strength of the paint film. At the same time, they can also improve the leveling of the system, eliminate the unevenness of the coating film, and improve the processing performance.

[0052] Preferably, the defoaming agent is at least one of BASF Foamaster MO 2111, BASF FoamStar ED 2522, BASF FoamStar SI 2213, BASF FoamStar SI 2227, BASF FoamStar SI 2293, TEGO Airex 904W, and TEGO Foamex 844.

[0053] Preferably, the pH adjuster is at least one of 2-amino-2-methyl-1-propanol, ammonia water, triethylamine, N,N-dimethylethanolamine, dimethylethanolamine, cyclohexylamine, and AMP-95 multifunctional auxiliary agent.

[0055] Preferably, the anti-settling agent is at least one of montmorillonite and fumed silica.

[0056] The anti-settling agent can prevent the filler in the composite emulsion from settling, and improve the leveling property, anti-sagging property, storage property and construction property.

[0057] Preferably, the drier is at least one of a cobalt salt drier and an isooctanoic acid rare earth drier.

[0182] Combining Examples 1-4 and Comparative Examples 4-5 with Table 1, it can be seen that the amount of activator material B added affects the crosslinking density of the asphalt paint film formed by curing. When the activator material B is too little, the crosslinking density of the asphalt paint film is too low, the density decreases, and the heat resistance and waterproof performance of the asphalt paint film are affected. When the activator material B is too much, the crosslinking density of the asphalt paint film is too high, the density is increased, the wear resistance and rigidity are improved, but it also leads to a decrease in the flexibility of the asphalt paint film, which cannot meet the requirements of low-temperature flexibility.

[0183] It can be seen from Example 1 and Comparative Example 6 and Table 1 that the asphalt paint film formed by curing with the compounded activator material B in the present invention has excellent corrosion resistance and also has good heat resistance and low temperature flexibility.

[0187] Combining Examples 1-4 and Comparative Examples 4-5 with Table 2, it can be seen that the amount of activator material B added affects the crosslinking density of the asphalt paint film formed by curing. When the amount of activator material B is too small, the crosslinking density of the asphalt paint film is too low, the density decreases, and the mechanical properties and weather resistance of the asphalt paint film are affected. When the amount of activator material B is too large, the crosslinking density of the asphalt paint film is too high, the density increases, and the mechanical properties and weather resistance are improved, but the elongation and fracture rate of the asphalt paint film decreases.

[0188] It can be seen from Example 1 and Comparative Example 6 and Table 2 that the asphalt paint film formed by curing with the compounded activator material B in the present invention has excellent corrosion resistance and good mechanical properties and weather resistance.
