Description
Technical field
The present invention relates to technical field of coatings, more particularly to a kind of anticorrosive paint.
Background technology
Coating, in the traditional entitled paint of China.Coating refers to be coated on body surface, under certain conditions a film-forming class I liquid I or solid material, and the film can play protection, decoration or other specific functions, such as insulation, antirust, mould proof, heat-resisting.In early days, most of coating is with vegetable oil as primary raw material, therefore is referred to as and paints.Now, vegetable oil is replaced on a large scale, the substitute is synthetic resin, therefore is referred to as coating now more.Coating is only not liquid, and anti-corrosion shape coating is also the major class of coating variety one.Coating is a kind of material, and this material can be coated in object surface with different construction methods, formed adhesion firmly, with some strength, continuous solid film, shape film common name film is also called paint film or coating.Coating can only be referred to as semi-finished product for the film for being formed.
Anticorrosive paint, is generally divided into conventional anticorrosive paint and anticorrosive paint, is essential a kind of coating in paint.Conventional anticorrosive paint is under general condition, etch-proof effect, the life-span that protection non-ferrous metal is used to be played to metal etc.；For anticorrosive paint refers to relatively conventional anticorrosive paint, can be applied in relatively harsh corrosive environment, and with a class anticorrosive paint of protection period longer than conventional anticorrosive paint can be reached.
The material property of anticorrosive paint is：（1）Can use under severe conditions, and with the long-effective corrosion life-span, anticorrosive paint can be used 10 years or more than 15 years in chemical atmosphere and marine environment, typically, even if in acid, alkali, salt and solvent medium, and under the conditions of uniform temperature, could be used that more than 5 years.（2）Thick-film is the important symbol of anticorrosive paint.The coating dry film thickness of general anticorrosive paint is 100 μm or 150 μm or so, and anticorrosive paint thickness of dry film is then at 200 μm or more than 300 μm, also 500 μm~1000 μm.Coating has remarkable weatherability, anti-aging, radioresistance, wear-resisting, impact resistance, high temperature resistant（400 DEG C~600 DEG C）, low temperature（-60℃）, stable conductivity；Its resistivity can meet antistatic requirement, and the long-life of coating is can guarantee that again.（3）Adhesive force is strong：Coating is strong with basal body binding force, and hydroxyl is contained in paint composite（-OH）, metallic matrix provides cation, can form chemical bonds, under the coupling agent in coating is helped, or even the combination for realizing covalent chain.In the case where space net structure is maintained, metal, metal oxide nano-material and the rare earth oxide ultrafine powder contained in coating composition help coating to form an interface transition layer for densification, its comprehensive macroscopic property is matched with matrix.（4）It is efficiently convenient：Easy construction, really realizes the normal temperature self-curing of inorganic coating, and when 20 DEG C of environment temperature, when relative humidity is less than 85%, surface drying 15min does solid work 2h, it is ensured that high efficiency is constructed, and is capable of achieving excellent salt fog resistance, ageing-resistant.Coating has self-repair, and the local cut that external force is caused can still be protected, and coating is not slit and welding damage, and band coating welding does not influence welding quality.
The content of the invention
It is an object of the invention to provide a kind of adaptability is good, nonpollution environment anticorrosive paint.
To realize above-mentioned purpose of the invention, the present invention provides a kind of anticorrosive paint, is made up of the component of following parts by weight：20-35 parts, n-butanol 15-20 parts, barium hydroxide 3-6 parts, film forming agent 1-5 parts, chromate 5-12 parts, defoamer 1-5 parts, water 30-60 parts of silicon-based polyurethane resin.
The chromate is sodium chromate or potassium chromate.
The defoamer is silicone emulsion.
Beneficial effects of the present invention compared with prior art.
The anticorrosive paint that the present invention is provided, raw materials used to have good environmental safety, production process will not also be polluted to environment, and raw material is easy to get extensively, and production cost is relatively low, is conducive to penetration and promotion, to the great significance of national economy.
Specific embodiment
The present invention is further described with reference to specific embodiment.
Embodiment 1.
The present embodiment provides a kind of anticorrosive paint, is made up of the component of following parts by weight：30 parts of silicon-based polyurethane resin, 18 parts of n-butanol, 4.5 parts of barium hydroxide, 3 parts of film forming agent, 8 parts of chromate, 2.5 parts of defoamer, 45 parts of water.
The chromate is sodium chromate or potassium chromate.
The defoamer is silicone emulsion.
The barium hydroxide is amphoteric compound, it is easy to and there is chemical action in soda acid nuisance, and realize antiseptic effect；Its corrosion-resistant principles of chemistry is exactly to neutralize as neutral innocuous substance harmful acid-base material to protect the material in corrosion-inhibiting coating not encroached on by corrosive substance.
The film forming agent can obtain fine and close corrosion-inhibiting coating to isolate antisepsis to by the injury of protection materials, it is ensured that the compactness of corrosion-inhibiting coating；Its corrosion-resistant physical principle is exactly that will be kept apart with the corrosive substance in the external world by protection materials with corrosion-inhibiting coating.
The chromate can react when moisture and oxygen are by antirusting paint and form anti-corrosion ion, be passivated the metallic surfaces such as steel, so as to prevent the dissolution of metal ion, reach corrosion-resistant purpose.
The application field of anticorrosive paint that the present embodiment is provided is：（1）Improve the essence of metal：That is alloy treatment：Alloy steel products with Cr, Ni, Cu, P, Si and rare earth etc. as base, there is excellent antiseptic property, and develop a series of seawater corrosion resistance steel on this basis.But the consideration based on economy and technological factor, above-mentioned element do not use largely in seawater corrosion resistance steel.（2）Form protective layer：That is coated non-metallic or coat of metal：Coat of metal is mainly carries out phosphorating treatment, oxidation processes, Passivation Treatment to coated metal；On-metallic protective coating is mainly and for the coating such as paint of coating, plastics, enamel, mineral grease to form protective layer on the metal surface.The purpose of both protective layers is to play isolation base material and contact with sea water, is reacted instead of base material and seawater, so as to form protection.
Specifically, anticorrosive paint application field mainly has following five aspects：1. emerging ocean engineering：Offshore Units, seashore and bay structure, offshore drilling platformses；2. Modern Traffic transport：Freeway guardrail, bridge, ships and light boats, container, train and railway facility, automobile, airport installation；3. energy industry：Water conservancy project equipment, water pot, gas tank, petroleum refinement equipment, oil stockpile equipment（Oil pipe, oil tank）, power transmission and transforming equipment, nuclear power, colliery；4. large size industrial enterprise：Paper making equipment, medical equipment, food chemistry equipment, canister inside and outside wall, chemical industry, steel, the pipeline of petrochemical plant, storage tank, mine smelting, cement plant, the ground for having corrosive medium, wall, cement components；5. urban operating mechanism：Gas piping and its facility（Such as gas chamber）, natural gas line, drinking-water facility, refuse treatment plant etc..
