Description

A kind of acid-alkali-corrosive-resisting water proof and wearable terrace paint and preparation method thereof
Technical field
The present invention relates to a kind of coating, a specifically acid-alkali-corrosive-resisting water proof and wearable terrace paint, this coating is applicable to the facility protection against corrosions such as various chemical production mill floor, business and school ground, Sport & Casual workplace ground, smelting and ground, industrial manufacturing shop, computer operation workplace ground, GMP pharmacy dust-free purification workplace ground and uses.
Background technology
At present, at terrace paint corrosion-resistant field, most use epoxy flooring coating, polyurethane floor coatings, its over-all properties is by the impact of its film forming matter: although epoxy flooring coating is fine with the cohesiveness of ground, but owing to adopting amine curing agent solidification, degree of crosslinking is limited, and wear resistance only reaches 0.03g/m 2(wear loss), after the short period of time uses, terrace surface just there will be the disadvantage such as cut, contamination; Although polyurethane floor coatings wear resistance compares epoxy flooring coating, be significantly improved, wear resistance reaches 0.02g/m 2(wear loss), but its wear resistance improves, and its snappiness and physical mechanical strength but reduce, and poorer than epoxy flooring coating with the cohesiveness of ground, are easy to cause obscission after the short period of time uses.In addition, polyurethane floor coatings generally use TDI prepolymer the different hydrogen acid ether of TDI(toluene two) be the one of conventional how different hydrogen ester, main exist free TDI and can damage human body, mainly sensitization and hormesis; Solidification physical property is crisp, and snappiness is not enough } as solidifying agent, the fragility of coating after constructing is increased.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of acid-alkali-corrosive-resisting water proof and wearable terrace paint and preparation method thereof, this coating has the excellent adhesive property of epoxy flooring coating and the excellent wear resistance of polyurethane floor coatings concurrently, and no longer adopt TDI prepolymer as solidifying agent, improve the comprehensive physicochemical property of product.
A kind of acid-alkali-corrosive-resisting water proof and wearable terrace paint of the present invention, its component and weight proportion are respectively:
Containing isocyanate curing agent component, i.e. polymeric MDI polyether prepolymer solution 50%-80%;
Hydroxyl colored paint component: BS965 Hydroxylated acrylic resin 17.5%-7%, polymer 6101 epoxide resin polymer 2.5%-1%, 582-2 aminoresin 1.5%-0.6%, pigment 18%-7%, dimethylbenzene 8%-3%, N-BUTYL ACETATE 2%-1%, BYK defoamer 0.2%-0.06%, 1% methyl-silicone oil 0.2%-0.06%, organophilic clay 0.5%-0.2%.
Described isocyanate curing agent component is: polymeric MDI polyether prepolymer 41.32%, N204 polyethers 8.26%, N330 polyethers 21.49%, 52 ° of clorafins 6.61%, dimethylbenzene 20.66%, 200# industrial napthas 1.65%.
The preparation method of described acid-alkali-corrosive-resisting water proof and wearable terrace paint, it comprises the following steps:
1) isocyanate curing agent component is first prepared:
The dimethylbenzene of polymeric MDI polyether prepolymer, total amount 5% is added reactor to stir and be warming up to 70-90 DEG C, start the mixture dripping N204 polyethers+N330 polyethers+52 ° of clorafins, dropwise at 1-1.5h, be warmed up to 90-100 DEG C of insulation reaction 5h, cool to less than 60 DEG C, add surplus dimethylbenzene and 200# industrial naptha latting drown filters and packages;
2) hydroxyl colored paint component is prepared:
By uniform stirring 15-25 minute after the mixing of BS965 Hydroxylated acrylic resin, polymer 6101 epoxide resin polymer, 582-2 aminoresin, pigment, dimethylbenzene, N-BUTYL ACETATE, BYK defoamer, 1% methyl-silicone oil and organophilic clay, then grind 1-3 time according to the fineness of material requirement, uniform stirring 10-25 minute makes, and filters barrelling and is finished product;
Add two components when 3, using, stir and come into operation
The present invention is owing to employing polymeric MDI (PM200) polyether prepolymer and Hydroxylated acrylic resin, macromolecule epoxy resin polymer resin system, wherein, the molecular structure of epoxy resin be with in molecular chain containing active epoxide group for its feature, epoxide group can be positioned at the end of molecular chain, centre or structure circlewise; Due in molecular structure containing active epoxide group, make they can with polytype solidifying agent generation crosslinking reaction and form insoluble, the not molten superpolymer with tridimensional network; Polymeric MDI (PM200) polyether prepolymer be have two functionality polyethers, three-functionality-degree polyethers and polyisocyanates under 90 DEG C of high temperature after polyreaction 5h with the polyurethane prepolymer of dimethylbenzene latting drown.This prepolymer, containing isocyanic ester, can with the hydroxyl reaction in epoxy resin, Hydroxylated acrylic resin, it also reacts with the steam in air simultaneously, and mixing generates insoluble, the not molten cured article such as urethane manthanoate, polyureas with tridimensional network.Coating has high bond strength, high-wear resistance, not embrittlement, anti-ruled area is good, acidproof alkali salt, the feature that water-fast, oil-proofness is good, due to these characteristics, ensure that the sticking power of product of the present invention to concrete, metal, synthetic materials etc., coating itself is very corrosion-resistant, good mechanical performance, has wear-resisting, shock-resistant, organic solvent-resistant, the characteristic such as heat-resisting, water-fast.
