Abstract
The present invention relates to bottom paint for coating surfaces with moisture and rust. The present invention is bi-component epoxy paint with low surface treating requirements. The paint comprises 10 shares by weight of component A and 1 share by weight of component B, wherein the component A of the paint is iron red and is compounded from bisphenol A epoxy resin, a moisture treating agent, a corrosion stabilizing agent, a penetrating agent, high-efficiency rust-proof pigment, filler, a sagging-proof auxiliary agent, etc.; the component B of the paint is brown and is compounded from a special type modified amine hardener with high performance, etc. Therefore, the paint has low treating requirements for surfaces, and the paint has strong adhesive force and good physical and mechanical performance; the paint has good matching performance with other paint, and the paint simultaneously has good performance of rust prevention and corrosion prevention.
Description
Technical field
The present invention relates to a kind of band and wet, be with the rust coating prime lacquer, especially refer to steel construction, pipeline, storage tank, tank car and equipment anticorrosion engineering in the industries such as naval vessel, chemical industry, machinery, make low supporting priming paint of surface treatment or independent coating prime lacquer as the protective system use.
Background technology
At present, coating is a kind of economical and effective the most and the anti-corrosion method that is widely used, and in the execution of coating process, in order to give full play to the antiseptic property of coating, general requirement is carried out surface treatment as far as possible completely, and constructs under less than 85% condition in humidity.
The surface treatment quality is vital to the influence in film performance and life-span, and relevant statistic data shows that the influence degree of surface treatment quality is 59%.High-quality process of surface treatment indoor steel surface pretreated stream waterline during except that shipbuilding and integral body, the segmentation shot-peening, mainly is the dry type blasting method, but a large amount of dust that the dry type sandblast brings, contaminate environment not only, and human body caused very big injury, be limited gradually to use.Therefore, abroad use in a large number to have high quality, high-level efficiency, oligosaprobic high pressure water (abrasive material) jet process for treating surface this year, domestic also have part unit to use on a small quantity.But after the hydroblasting, especially by the sea, steel are understood generation " returning rust " phenomenon rapidly, and surface moisture is very big, and domestic showing all can not directly be carried out application with coating.Past is adopted the method for adding 1% inhibiter (as Sodium Nitrite) in water, not only causes a large amount of extraneous expenses, and coating is had certain influence.The external main large-scale drying plant (as high-pressure air and oven dry, exhaust equipment etc.) that adopts solves, and has the big problem of funds expenditure equally, has seriously restricted the large scale application of high pressure water (abrasive material) jet process for treating surface.
In addition, at some in particular cases, as rainy day construction and at narrow and small cabin, machine bottom, the angle steel back side and the pipeline of facilities and equipments such as boats and ships and the electric wire place etc. that arranges, area and import and export are all very little, often be difficult to carry out surface treatment completely, handle common corrosion and the rusty stain that still has in various degree in back, and often be in moist state, at the common coating of the direct application in the halfway surface of this processing, its life-span have only usually the original design life-span half in addition lower.
At present, low surface treatment paint---refer to the coating low, more and more be subjected to the attention of countries in the world, develop very soon, be coated with and load onto, can be used for containing the direct application of substrate surface of the following rusty scale of 80 μ m usually but mainly concentrate on band rust to surperficial processing requirements.Primer for rusty surface is very fast in China development, uses also a lot, has tentatively solved become rusty application problem of the band thoroughly time of rust cleaning.But they all can not be with wet application more for a long time at surface-moisture.
In addition, also in development, this part coating is solventless coatings to painting under water, as non-solvent epoxy painting under water coating and wet cured polyurethane paint, relies on special constructional method with coating, solves the problem of application in the water.But restraining factors such as flowability is poor, constructional difficulties that solventless coatings exists can not be directly used in the service requirements of high humidity, band rust occasion.
Existing at present can have only water-borne coatings with the coating of wet application, mainly is that dependence water is the characteristic of solvent, can be in the directly application of the surface of humidity.As CN 1075324 patents described " band rust band oil band oil bound water paint and preparation method thereof ", it relies on the purpose that emulsifying agent reaches oil removing; Rely on the rust stablizer and solve band rust application problem; Rely on aqueous solution characteristic and solve band water application problem.But the complex protection capability of water-borne coatings can not show a candle to solvent based coating at present; especially antirust ability is significantly less than organic solvent coating; and this class water-borne coatings is owing to relying on the normal volatilization film forming of water, so wait the big place use of ambient moisture can bring the thorough and problems such as " sudden strain of a muscle rust " of drying by the sea.
Take a broad view of existing both at home and abroad coating variety, also do not have a kind ofly to be adapted at that high humidity environment uses, can be simultaneously with the solvent-borne type high-performance low surface treatment paint of rust, the wet application of band.
Summary of the invention
The purpose of this invention is to provide a kind of band and wet, be with the rust coating prime lacquer, realized low-temperature curing by selecting high-performance special modification long-chain phenolic aldehyde amine epoxy hardener for use; By adding bisphenol A epoxide resin and the moisture content treatment agent good to the water affinity, coating can directly be coated be contained in humidity, even the body surface that has moisture film to exist, by adding the corrosion stablizer and having chemosmotic high-performance tensio-active agent and highly effective antirust face, filler and sag prevention auxiliary agent etc., coating can be coated with simultaneously be contained in the body surface that contains a small amount of corrosion, thereby provide a kind of can be directly in moist and a small amount of corrosion steel surface application, and oil resistant with extremely strong sticking power and excellent physical and mechanical properties and excellence, water-fast, acid and alkali-resistance, salt spray resistance can be wet with the good supporting high performance tape of most coating, band rust coating prime lacquer.
