Description

Technical Field

[0001] The present application relates to the technical field of preparation of functional water-based asphalt coatings, and in particular to a water-based asphalt anti-pest and anti-corrosion coating and a processing technology thereof. Background Art

[0002] As a major importer and exporter, my country's container throughput has exceeded 300 million since 2003. As a special tool for international transportation and logistics, containers travel between land and sea and need to be coated with anti-corrosion coatings to withstand the erosion of harsh climates. At present, there are two main types of anti-corrosion coatings for containers: traditional solvent-based asphalt coatings and environmentally friendly water-based asphalt coatings. Solvent-based asphalt coatings will produce large amounts of volatile organic compounds (VOCs) during construction, which are prone to secondary environmental pollution and endanger the health of construction workers. Therefore, they have been gradually replaced by environmentally friendly water-based asphalt coatings.

[0003] Existing water-based asphalt paints, such as the special container bottom anti-rust asphalt paint disclosed in announcement number CN 105950017 B, select high-quality refined solvents and road asphalt, add anti-rust wax and additives with good plasticizing properties, and cooperate with organic bentonite, heavy calcium powder, etc. to adjust the appropriate viscosity to facilitate on-site construction. After the solvent evaporates, a long-term anti-corrosion and harsh condition resistant black shiny protective film is formed on the bottom of the container.

[0004] In recent years, public health and safety incidents and alien species invasions caused by imported containers have been reported from time to time. The problem of pests and diseases encountered in container transportation has become increasingly prominent. The hardest-hit areas where pests and diseases frequently occur are mainly concentrated in refrigerated goods, food goods, or other containers that may inadvertently transport harmful organisms.

[0005] Although the existing anti-corrosion coatings for containers have a good anti-corrosion and anti-rust effect, they still cannot effectively solve the problem of pests and diseases. Although it is reported in existing literature that the introduction of mildew inhibitors and antibacterial agents into the formula of anti-corrosion coatings for containers can avoid public health and safety incidents caused by the spread of microbial invasion to a certain extent, it is still unavoidable to encounter pest problems. The main problem of container pests is that the regional environment and climate of container loading vary greatly, and the levels of health quarantine also vary. It is inevitable that harmful organisms will be inadvertently mixed in during the loading of containers, which will not only cause damage to the goods, especially cause serious health and safety hazards to cold chain foods, but also the mixed harmful organisms will spread diseases and cause collective public health and safety problems. Even harmful organisms enter the container unloading area. Because there are no natural enemies to limit them, they reproduce in large numbers, causing biological invasion problems and seriously damaging the ecosystem.

[0006] Pests mixed in containers, such as common cockroaches and borers, not only damage the cargo, but also carry a variety of pathogens, posing a threat to human health; such as jewel beetles, longhorn beetles, termites, etc., can also cause serious damage to cargo and even affect the balance of the entire ecosystem. Therefore, a water-based asphalt anti-pest and anti-corrosion coating and its processing technology are urgently needed. Summary of the invention

In summary, the asphalt base coating / insect-proof polymer coating formed by curing the asphalt insect-proof and anti-corrosion coating of the present invention can not only have good anti-corrosion and anti-rust durability, but also have good insect-proof effects and insect-proof durability. That is, the present invention has an effective anti-corrosion and anti-rust effect and at the same time has an excellent and lasting anti-disease and insect-pest effect.

[0020] The polyurethane latex particles in the pest-proof filler are first physically adsorbed on the porous inorganic filler carrier, and the active matrix on the polyurethane latex particles is bonded with the active groups on the surface of the porous inorganic filler carrier, so that the polyurethane latex particles are firmly connected to the porous inorganic filler carrier. The polyurethane latex particles can be firmly grafted to the asphalt base coating, which can ensure that the pest-proof polymer coating has excellent pest-proof durability.

[0021] Preferably, the preparation process of the pest-proof filler is as follows: Step 1: placing the porous inorganic filler in a low-temperature plasma treatment device, and performing low-temperature plasma treatment for 10-15 minutes at 0-4°C and nitrogen or nitrogen-oxygen mixed gas, with a plasma generator frequency of 40KHz, a power of 100-300W, and a nitrogen input of 40-80L / h, to obtain a plasma-modified porous inorganic filler; Step 2: placing 10 parts by mass of the plasma-modified porous inorganic filler in 200-400 mL of a 0.4-0.8 wt% aqueous solution of a siloxane coupling agent, wherein the siloxane coupling agent in the aqueous solution of the siloxane coupling agent comprises at least epoxy silane, adding 0.5-1 mL of a 0.1 mol aqueous solution of hydrochloric acid, stirring at 100-200 rpm for 1-3 min, and then performing ultrasonic dispersion treatment for 15-30 min at an ultrasonic frequency of 40 kHz and an ultrasonic power of 300-600 W, filtering, and drying to obtain an epoxy-modified porous inorganic filler; Step 3, 0.5-1.5 parts by weight of an organic synthetic insect repellent is added to 200-250 mL of deionized water, wherein the organic synthetic insect repellent is at least one of 4-nitrophenyl carbamate, (3-methylazetidin-3-yl) methylcarbamic acid tert-butyl ester, and malathion monocarboxylic acid, and after mixing evenly, 10 parts by weight of an epoxy-modified porous inorganic filler is added, and the mixture is heated to 60-65° C. in a water bath, and the mixture is maintained at 60-65° C. and 100-200 rpm for 20-40 minutes.

By controlling the mass ratio of polyurethane latex particles to insect repellent filler, the bonding stability of the insect repellent filler and the asphalt base coating can be adjusted, thereby improving the durability of the insect repellent effect.

[0025] In addition, the particle size of the pest-proof filler also needs to be optimized. Although a particle size that is too large can improve its bonding stability with the asphalt base coating, it will affect the overall pest-proof effect and the durability of the pest-proof performance.
