Description
Technical Field
The invention relates to the field of coatings, in particular to a long-acting protective water-based phenolic epoxy static conductive coating and a preparation method thereof.
Background
With the promotion of strategic petroleum reserves in China and the development of petrochemical industry, the demand for storage tanks for crude oil and petroleum products is increasing. Crude oil and oil products have strong corrosiveness and permeability, and are extremely easy to corrode the inner wall of the storage tank; static electricity can be generated due to friction in the transportation and storage processes, and if accumulated static electricity cannot be removed in time, accidents such as static electricity ignition and explosion can occur at any time. The national Petroleum administration specifies in GB13348-2009 standard of the liquid Petroleum product static safety Specification that antistatic paint should be used for the "inner wall of an oil tank" and the table shows thatThe area resistivity should be at 10 8 ～10 11 Within the omega range, GB50393-2008 technical Specification for anti-corrosion engineering of Steel Petroleum storage tanks clearly requires the performance indexes of static conductive anti-corrosion paint and coating.
The static-conductive anticorrosive paint is mainly divided into two main types, namely an intrinsic type and an additive type. The intrinsic static conductive anticorrosive paint does not need to be added with a static conductive material, the static conductive stability is longer due to the self conduction of the resin matrix, and the practical application of the intrinsic static conductive paint in the anticorrosive field is greatly limited due to the complex production process of a resin system, high cost and the like. The resin matrix of the additive type static-conductive anticorrosive paint is not conductive, so that the static-conductive filler is required to be added to achieve the purpose of static conduction. The additive conductive filler mainly comprises three main types of carbon-based, metal-based and metal oxide-based. The carbon conductive filler has low price and good static electricity conducting performance, but can seep into oil products in practical application to influence the quality of the oil products; the carbon-based filler also readily forms electrochemical corrosion with the metal substrate, which becomes the anode and accelerates corrosion. The metal and metal oxide conductive filler is expensive, and is limited in practical popularization and application.
The static conductive anticorrosive paint which is commercialized and used on a large scale in the petrochemical industry is mostly solvent-type paint, and has excellent chemical resistance, oil resistance and anticorrosive performance, but has great hidden trouble in construction safety. The inner wall of the storage tank is constructed in a closed environment mostly, air does not circulate, the solvent type coating not only affects the health of constructors, but also causes flash explosion accidents in the oil tank due to volatile organic matters. Therefore, from the viewpoints of safety and environmental protection, the waterborne static-conducting anticorrosive paint has become a necessary development trend nowadays.
At present, the environment-friendly water-based static-conductive anticorrosive paint which is pushed out by some enterprises is mainly made of water-based epoxy resin, but a series of defects which are difficult to overcome always exist, for example: the paint is slow to dry, cannot be cured at low temperature, has poor weather resistance when being used outdoors, has larger difference in chemical resistance and corrosion resistance than solvent type paint, is only suitable for carbon steel substrates in practical application, and has the problems of poor adhesive force to nonferrous metal surfaces and the like.

Table 2 main technical index of waterborne phenolic epoxy static conductive coating
Test results show that the aqueous phenolic epoxy electrostatic-conducting paint for long-acting protection, which is applicable to the surfaces of various substrates such as carbon steel, aluminum alloy, stainless steel, galvanized sheet, concrete and the like, has long application period, good construction property, quick drying and low-temperature curing, and has high electrostatic-conducting stability, excellent adhesive force, water resistance, boiling resistance, chemical resistance, good weather resistance and excellent corrosion resistance, is obtained in examples 1 to 4.
From the test results of examples 1 to 4, the coating prepared by using the high-content graphene-carbon nanotubes and the low-content silver-coated aluminum powder of example 4 is superior to the coating prepared by using the low-content graphene-carbon nanotubes and the high-content silver-coated aluminum powder of example 1 in conductivity, hot water resistance, chemical resistance and corrosion resistance. The three-dimensional network conductive network with stable conductivity is formed by the synergistic action of a dot-shaped/linear/plane-shaped ternary conductive system consisting of modified graphene/carbon nano tube/silver coated aluminum powder in a coating. The introduction of the graphene and the carbon nano tube not only can effectively reduce the consumption of the conductive filler, but also can obviously improve the mechanical property and exert the water vapor shielding effect by virtue of the special structure, and improve the corrosion resistance.
From the results of comparative example 1 and example 1, it was found that an electrostatic conductive coating having low surface resistivity and high efficiency and stability could not be obtained by using an unmodified graphene-carbon nanotube aqueous dispersion, and the hot water resistance, chemical resistance and salt spray resistance of the coating were all lowered. The unmodified graphene and the carbon nano tube are difficult to disperse uniformly in a coating system, are easy to agglomerate, cannot exert excellent conductivity, mechanical property reinforcement and water vapor barrier effect, and the comprehensive performance of the coating is reduced.
From the results of comparative example 2 and example 2, it is clear that the use of the aqueous epoxy-modified acrylic resin is important for improving the artificial aging resistance of the coating, and also helpful for prolonging the activation period and improving the drying property. The double-resin film forming system which adopts the aqueous phenolic epoxy emulsion and the aqueous epoxy modified acrylic resin as film forming materials effectively integrates the characteristics of phenolic resin, epoxy resin and acrylic resin, and the long-acting protective aqueous phenolic epoxy electrostatic conductive paint is prepared, has excellent adhesive force, water resistance, acid and alkali resistance, corrosion resistance and weather resistance, and therefore, the applicability is wider, the protective life is also higher, and the maintenance cost of the whole life cycle can be greatly reduced.
From the results of comparative example 3 and example 3, it is known that the aqueous curing agent is prepared by compounding cardanol modified phenolic amine and modified aliphatic amine, and the aqueous curing agent can be synergistically complemented, so that quick-drying and low-temperature curing of the phenolic amine curing agent can be brought into play, the aliphatic amine curing agent has good adhesion, excellent water resistance, excellent corrosion resistance and heat resistance, good flexibility, good weather resistance and long pot life, and the coating system has excellent comprehensive properties through reasonable proportioning screening.
As can be seen from the results of comparative example 4 and example 4, by compounding organically modified zinc in inorganic zinc phosphate Hall SZP-391RZ can exert the synergistic effect of organic and inorganic, can exert the rust-proof effect under lower dosage, and greatly improves the corrosion resistance. It has been found in experiments that the use of flaky silica fume having excellent acid resistance in the filler also contributes to the chemical resistance, salt spray resistance and weather resistance of the coating system.
From the results of comparative example 5 and example 4, it is known that the silane coupling agent is adopted for modification, so that a strong binding force covalent bond can be formed between the silane coupling agent and the aqueous organic resin, the inorganic pigment and filler and the substrate, the adhesion of the coating to the substrate is improved, the silane coupling agent is applicable to various substrates (carbon steel, aluminum alloy, stainless steel, galvanized sheet and concrete), and the hot water resistance and corrosion resistance of a coating system are also obviously improved.
