Description
Technical field
The present invention relates to a kind of two-pack painting and production method and usage, especially based on the painting that is used for priming paint of Resins, epoxy.
Background technology
Paint be meant be coated onto body surface can dry film forming, make object attractive in appearance and be protected, perhaps form a class filmogen with other specific function film at body surface.Therefore paint is a multicomponent system, is generally thick liquid, because the effect of paint is to different object planes, shields in different environment, needs mechanical strength, characteristics such as ageing-resistant, corrosion-resistant.
The filmogen of paint uses macromolecular compound more; be commonly referred to as coating resin; it should have following performance: solvability is good; compatibility is good; good film-forming properties and to the wettability of pigment and can give the certain protection and ornamental of filming; also want good stability simultaneously, certain quality guaranteed period is arranged.Coating resin divides with its source, and natural resin, artificial resin and synthetic resins three major types are arranged.Synthetic resins is to use maximum, the best filmogen of performance in the present paint industry, such as Resins, epoxy, urethane, polymeric amide, polyester, resol, aminoresin or the like, all is widely used in paint industry.
The paint that China produces is various in style, but all belongs to usual production, far can not adapt to the requirement of China's high-technology industry development, and is especially true in the anti-corrosion of metal field.Corrosion of metal is that metal is subjected to the chemistry of surrounding medium or electrochemical action and ruined phenomenon.Corrosion of metal spreads all over the national economy every field, has brought tremendous loss to national economy.For a long time, one of method that the hardware protection against corrosion is effective, the most the most frequently used is at metallic surface coating erosion shield, with isolated corrosive medium and metallic matrix.Its prescription is formed and is mainly comprised binder resin, pigment, filler and solvent.Binder resin is a filmogen, is its main component, and its molecular structure is determining the salient features of paint.Can be a lot of as the resin of coating resin, different resins has different separately characteristics, has outstanding advantage simultaneously, and unsurmountable shortcoming is also arranged, such as, urethane resin has excellent Corrosion Protection, strong adhesion, wear-resisting, physical and mechanical properties is good, but its poor water resistance.Resins, epoxy is a kind of good coating material, as the paint that base-material is produced, has good sticking power, chemical proof, hardness, snappiness and fastness with it.Shrinking percentage is minimum during curing, and the mechanical property and the electric property of cured article are good, but its weathering resistance is poor, the easy efflorescence of paint film, loss of gloss.Therefore, present industrial two-pack or the multi-component painting of occurring, purpose is that various coating resins are used, advantages is got up separately, can also overcome shortcoming each other simultaneously.In CN 1061674C, disclose first, second two components based on the two-component priming anticorrosive paint of Resins, epoxy, the first component comprises that molecular weight is that 190～600 Resins, epoxy, molecular weight are that 600～1700 Resins, epoxy, iron oxide red, zinc yellow, zinc phosphate, wilkinite, filler, solubility parameter are 8～17, and viscosity is the organic solvent of 0.5～30 centipoise in the time of 20 ℃; The second component comprises that phenol aldehyde modified polyamine, amine value are that 200～600 polymeric amide, softening agent, iron oxide red, solubility parameter are 8～17, and viscosity is the organic solvent of 0.5～30 centipoise in the time of 20 ℃.This coating improves corrosion resistance and work-ing life greatly.This patent is with Resins, epoxy and two kinds of resin-bonded of polymeric amide, synergy, though improved the Corrosion Protection of coating to a certain extent, but still can not satisfy the needs of high-technology industry development fully.How the multiple coating resin with different characteristics is used, and is still the problem that the present utmost point need solve.
When the hardware surface applied is painted, generally need carry out high bake to the paint of coating, it can be solidified rapidly, this brings very big inconvenience with regard to the construction of giving paint, so easily construction also is a direction of paint industry development.
Summary of the invention
The object of the present invention is to provide a kind of two-pack painting that is used for priming paint, this invention has that strong adhesion, good toughness, stain resistance are good, wear-resisting, salt spray resistance, anti-gasoline, acid and alkali-resistance, electrical insulating property are good, shock-resistant, high temperature resistant, cold-resistant, the characteristics of good flame resistance, and energy spontaneous curing, be easy to construction, can be used as the priming paint of paint coating.
Another object of the present invention is to provide a kind of working method that is used for the two-pack painting of priming paint.
An also purpose of the present invention is to provide a kind of using method that is used for the two-pack painting of priming paint.
In order to realize the object of the invention, the invention provides a kind of two-pack paint that collects the polyploid organic resin, one group is mainly adopted hydroxyl (OH) bis-phenol base propane and epoxy chloropropane synthetic resin; (NCO) two amido toluene affixtures are with two mixed joining of component for isocyanic ester for another group.Utilize (OH) with (NCO) cross-linking reaction, leave standstill, solidify, it is good to generate a kind of function, natural, graceful and poised plentiful, bright-coloured paint film.
In order to realize the object of the invention, the invention provides a kind of two-pack painting that is used for priming paint, it is characterized in that by A, two kinds of components of B constitute, the composition of A component comprises by weight: 25 parts～40 parts of Resins, epoxy liquid, 1 part～5 parts in aminoresin, 30 parts～45 parts of fillers, described Resins, epoxy liquid comprises 20 parts～30 parts of Resins, epoxy, 2 parts～8 parts of linear epoxy resins, 5 parts～12 parts in butanols, 6 parts～15 parts of pimelinketone, 12 parts～20 parts of dimethylbenzene, the composition of B component comprises by weight: 35 parts～50 parts of polyamide resins, 28 parts～36 parts of dimethylbenzene, 20 parts～28 parts of pimelinketone, 1 part～5 parts of siccative mixed with the B component A component by 3: 1～8: 1 weight ratio.
The composition of A component of the present invention also may further be (by weight): 34 parts～36 parts of Resins, epoxy liquid, 1.5 parts～3 parts in aminoresin, filler: 35 parts～42 parts, described Resins, epoxy liquid comprises 26 parts～28 parts of Resins, epoxy, 3 parts～6 parts of linear epoxy resins, 6 parts～11 parts in butanols, 8 parts～11 parts of pimelinketone, 16 parts～18 parts of dimethylbenzene, the composition of B component comprises by weight: 46 parts～48 parts of polyamide resins, 28 parts～36 parts of dimethylbenzene, 24 parts～26 parts of pimelinketone, 1 part～2 parts of siccative mix with the B component A component by 4: 1～6: 1 weight ratio.
