Description
Technical Field
The utility model relates to a coating structure, especially a strong constructability hinge spare waterborne low temperature seal coat structure.
Background
The coating structure of the existing door hinge part usually adopts oil paint, the oil paint has the advantages of fast curing, bright color and the like because of adopting an oil solvent, but the problems of volatility, irritation and the like inevitably exist because of adopting the oil solvent, in addition, the humidity of a construction place is particularly required to be noticed, and the construction cannot be carried out when the humidity is too high. Along with the promotion of environmental protection and health consciousness, the water-based paint is adopted for coating in the industry, but the problem of the existing water-based paint is that: high-temperature drying and curing are needed, and the water resistance is poor.
Disclosure of Invention
To the deficiency of the prior art, the utility model provides a low temperature is curable waterborne coating structure promptly. The structure does not change the chemical properties of each coating, but through the reasonable combination of the structure, the coating structure does not need high-temperature curing, and has better water resistance.
The technical scheme of the utility model is that:
the utility model provides a strong constructability door hinge waterborne low temperature seal coat structure which characterized in that: it includes sealant layer, waterborne epoxy paint layer, filling layer, waterborne floating coat, waterborne varnish layer and waterborne finish paint layer, the coating of sealant layer is on door hinge spare surface, and waterborne epoxy paint layer coating is on the sealant layer, and the filling layer coating is on waterborne epoxy paint layer, and waterborne floating coat coating is on the filling layer, and waterborne varnish layer coating is on waterborne floating coat, and waterborne finish paint layer coating is on waterborne varnish layer, and the sealant layer material is the water-soluble sealant. The water-soluble sealant is a water-based system, has high corrosion resistance and strong adhesive force, does not contain harmful substances such as formaldehyde, benzene, heavy metal and the like, is beneficial to environmental protection and the body health of operators, is a transparent bright film after being dried, can be used as an anticorrosive coating, and can also be used as an antirust primer. The water-based epoxy paint layer can enhance the corrosion resistance and also can be used as the attachment surface of the filling layer. The filling layer can play a role of leveling. The water-based intermediate coating can be used as an attaching surface of a water varnish layer. The water-based finish paint layer is used as a protective layer.
Furthermore, the material of the filling layer is atomic ash. The leveling and filling effects are excellent.
In some embodiments, a base color layer is further arranged between the filling layer and the water-based middle coating, and the base color layer is a water-based base color paint. The utility model discloses can make present predetermined colour.
In some embodiments, the aqueous topcoat layer is further coated with a hydrophobic coating. Its benefit is promoting by a wide margin the utility model discloses a water proofness.
The utility model has the advantages that: the sealing agent layer is directly contacted with the door hinge, the water-based sealing agent has lower requirements on construction conditions, and the construction is not influenced even if the field humidity is higher; after construction, high-temperature baking is not needed, and curing can be realized under a low-temperature condition (lower than 50 ℃).
