Description

A kind of organic porcelain of water-based pre-roller coat metal colored steel
Technical field
The utility model relates to the organic porcelain of a kind of water-based pre-roller coat metal colored steel, belongs to decorative building material technical field.
Background technology
Along with the development of coatings industry, the pattern of coating, kind, function get more and more, and divide the work also more and more thinner.But traditional solvent-borne coating is thinner mainly with organic solvents such as toluene, dimethylbenzene, N-BUTYL ACETATEs, it manufactures and construction process causes huge pollution because of a large amount of discharge of organic solvent to environment.Be limited the discharge of organic solvent processed, and the high solids content of coating, organic solvent-free, Water-borne modification, high utilization rate are in the gesture be growing steadily.Wherein, the Water-borne modification of coating is a development in recent years field very rapidly.Water-borne coatings take water as diluting solvent, silicon, fluorine element, inorganic salt, organism are combined the high polymer alloy hybridized to together, volatile matter in film process, both can not produce HUMAN HEALTH and threaten, a large amount of use also can not pollute room air and atmospheric air quality, and can meet the requirement of various color imagination.
In the disaster of subway, fire hazard is the most serious.Due to the Architecture and environment feature of subway, if the enclosed environment presence of fire such as tunnel, station, train within the service time, high temperature, along with poisonous dense smoke, adds the feeling of terror be trapped in a finite space, thus increases the possibility that the dead group of generation group hinders serious consequence.In subway station, track traffic operational process, mobility of people is large in addition, and also large to the colliding with of finishing material, abrasive damage probability, surperficial contaminated possibility also increases.At kitchen electrical domain, high temperature resistant, scratching, performance requriements easy to clean are also existed equally to the requirement of material.
The pre-roller coat product of water-based on market is few, the false aqueous coating product even having bad businessman to adopt oil primer to add aqueous finish paint or aqueous priming paint to add " two skins " that oiliness finish paint is made.Existing class ceramic coating mostly is solvent-borne type spraying coating, and require higher to the condition of surface of substrate in construction process, sandblasting, shot peening need be done, complex procedures, special board with enamel panel layer even needs 800 ~ 1000 DEG C to sinter, and production unit drops into high, energy consumption is large, pollute large, cost is higher, and hardness is high but crisp.In published patented technology, 200410014277.6 " organosilicon-ceramic coatings of resistance to 900 ~ 1200 DEG C of high temperature " are mainly to the utility model that coating resistance to elevated temperatures is studied, to fire prevention, high rigidity, the performance such as self-cleaning and application product is rare relates to; CN101857772A " scratch resistance nano inorganic-organic polymer paint and application thereof ", although the coating aquosity nano polysilicon oxygen alkane that relates to, only accounts for 20 ~ 30% of total amount, does not claim water-borne coatings, and just emphasis to the utility model of adhesion strength.
Before the utility model completes, there is not yet the patent report adopting the pre-roller coat production technique identical with the utility model and product, do not see the performance index identical with the utility model, the product of Application Areas commercially sells.
Based on this, make subject application.
Utility model content
In order to overcome the above-mentioned defect existed in prior art, the utility model provides that a kind of glossiness is high, high rigidity, scratch resistance, the organic porcelain of high temperature resistant, corrosion-resistant, that there is self-cleaning function water-based pre-roller coat metal colored steel.
For achieving the above object, the technical scheme taked of the utility model is as follows:
A kind of organic porcelain of water-based pre-roller coat metal colored steel, from bottom to top be followed successively by the organic porcelain facing enamelled coating of preprocessing layer one, metal substrate, preprocessing layer two, waterborne basecoat and water-based, described waterborne basecoat is the laminate structure formed by a kind of or several combination in water-base epoxy, polyester or polyurethane coating systems, water-based organic porcelain facing enamelled coating is the high polymer alloy layer formed by many organoalkoxysilanes and aqueous inorganic polysiloxane hybrid, and aqueous priming paint layer thickness is 6-10 μm, the organic porcelain surface paint layer thickness of water-based is 10-15 μm; Described preprocessing layer one and preprocessing layer two lay respectively at upper surface and the bottom surface place of metal substrate, and this preprocessing layer one and preprocessing layer two are integral type structure with metal substrate.
Further, as preferably:
The organic porcelain facing enamelled coating of described water-based is covered with protective membrane and forms protective film.More preferred, described protective film is that 4 ~ 6 transparent films of polyethylene or polyvinyl chloride are covered on the laminate structure that the organic porcelain facing enamelled coating of water-based is formed.
The surface gloss (60 of described waterborne basecoat and the organic porcelain facing enamelled coating of water-based o) scope all can reach 5 ~ 90.
Principle of work of the present utility model and beneficial effect as follows:
1) in the utility model, waterborne basecoat and the organic porcelain facing enamelled coating of water-based are all by the high polymer alloy layer of the high solid water-borne coatings of organic inorganic hybridization, the plate finishing coat mass effect parameters such as plate finishing coat sticking power, density, finish are high also improve, the volatile quantity of organic solvent can be reduced, do not have the harmful chemical releases such as formaldehyde, benzene, dimethylbenzene, VOC discharges comparatively solvent based coating and reduces more than 80%, and ensure that coating and metal substrate, the sticking power that coating is enough each other.
2), in the utility model, the coating matrix resin of waterborne basecoat and the organic porcelain facing enamelled coating of water-based is organic inorganic hybridization.Water-based organic porcelain tricoat finish matrix resin is carry out the obtained high polymer alloy of hydridization containing many organoalkoxysilanes such as methyl, phenyl, vinyl and aqueous inorganic polysiloxane, organic constituent provides enough gloss, cracking resistance, low surface energy and the snappiness of coating, and inorganic component provides hardness, the rigidity of coating.
3) not only to have gloss range adjustable between 5 ~ 90 for metal colored steel of the present utility model, color is unrestricted, various color imagination and machining needs can be met, especially high temperature resistant, the function such as resistance to acid attack, scratch resistance, high rigidity, fire line, weathering resistance is splendid, and there is automatically cleaning ability, its pencil hardness can reach 4H, resistance to burning grade A1, produces cigarette toxic smoke classification AQ1.
The organic porcelain of the utility model water-based pre-roller coat metal colored steel can be widely used in household electrical appliances, kitchen electricity, the place of people's stream aggregations such as track traffic subway station, railway station, train upholstery, exhibition center, stadiums, has high temperature resistant, resistance to acid attack, scratch resistance, high rigidity, fire line, weathering resistance and self-cleaning function.
