Abstract
Originally practical to be newly related to a kind of protective coating of body of a motor car water paint application; it is applicable in automobile industry; it discloses the dew on body structural member and is covered with epoxy primer layer; water-borne base coat layer is covered on the epoxy primer layer; it is covered with water varnish layer on the water-borne base coat layer, this practical new weatherability is excellent, and anti-stone hits, scratch-resistant; the plentiful beauty of bloom, environmental protection and energy saving.
Description
Technical field
Originally practical to be newly related to water paint field, and in particular to a kind of protection painting of body of a motor car water paint application
Layer.
Background technology
These years, with the fast development of auto industry and the continuous improvement of living standards of the people, China becomes in the world
Maximum automobile production and marketing state, but domestic automobile application coating has based on solvent-based system containing a large amount of volatility at present
Machine object causes pollution to environment and is on the rise, and with the reinforcement of people's environmental consciousness and perfecting for environmental regulation, volatility has
The discharge capacity of machine object (VOC) is limited by being increasingly stringenter, and the Water-borne modification of car paint is the inexorable trend of development.But now
In some aqueous automobile vehicle body coatings, water-base epoxy priming paint effect and comprehensive strength difference aqueous finish paint layer are in weatherability, machinery
It is undesirable in terms of performance and appearance
Invention content
This practical new technical problems to be solved is to provide a kind of protective coating of body of a motor car water paint application,
Aqueous functional epoxy primer layer is excellent to body structural member anti-corrosion effect and comprehensive strength, and entire inter-coat adhesion is strong, aqueous
Layer of varnish realizes that bloom is plentiful, weatherability is excellent, and paint film is hard and flexible, and anti-stone hits, scratch-resistant, and good protection is played to vehicle body
Decoration function.
This practical new technical solution is, originally practical newly to exist on the basis of the body structural member of the prior art
Dew is covered with epoxy primer layer on body structural member, water-borne base coat layer is covered on the epoxy primer layer, described aqueous
Background color enamelled coating overlying is covered with water varnish layer.
The thickness of aqueous functional epoxy primer layer and water-borne base coat layer described above is 15-25 μm.
The thickness of this practical new water varnish layer is 30-35 μm.
It includes newly aqueous functional epoxy primer layer, water-borne base coat layer and water varnish layer, aqueous background color layer that this is practical
It overlays on aqueous functional epoxy primer layer, aqueous enamelled coating overlays on waterborne basecoat.Aqueous functional epoxy primer layer, using powder
It restores auxiliary agent with fine zinc-rich compound to coordinate, there is stronger reproducibility, be obviously improved the anti-corrosion effect to body structural member
Fruit, and inorganic fibrous fillers are provided, so that coating integral strength is improved；Water-borne base coat realizes body color and metal effect
Fruit；Water varnish layer reaches excellent paint film property by isocyanate group cross-linking reaction.Realize that vehicle body is smooth, bloom is rich
It is full, while the protection and decorative effect to sunlight, rainwater, branch or other scrapings etc. being provided.
Originally practical new advantageous effect compared with prior art is：
Originally practical newly to remove floating coat, this aqueous functional between aqueous functional epoxy primer layer and water-borne base coat layer
Epoxy primer layer, while realization to vehicle body metalwork anti-corrosion protection, improving anti-stoning can be with upper layer water-borne base coat
Adhesive ability removes middle priming layer from, realizes energy conservation；Water varnish layer reaches excellent using double-component waterborne polyurethane varnish
Different paint film property plays good protection and decorative effect to vehicle body.
In conclusion this practical new advantage is that bloom is plentiful, has excellent weather resistance, stone, scratch-resistant and beauty are resisted,
Environmental protection and energy saving.
Description of the drawings：
Fig. 1 is this practical new structural schematic diagram
This practical is newly further described in detail with reference to the accompanying drawings and detailed description
Specific implementation mode：
It includes body structural member described in Fig. 1, this is practical new especially in body structure
It is covered with epoxy primer layer 1 on part 4, is covered on the epoxy primer layer 1 aqueous
Background color enamelled coating 2, the epoxy primer layer 1 and 2 two layers of thickness of water-borne base coat layer are at 15-25 μm.In the water
It is covered with water varnish layer 3 on property background color enamelled coating 2, it is described
The thickness of water varnish layer 3 is 30-35 μm.Aqueous functional epoxy primer layer 1, using powder reduction auxiliary agent with it is micro-
Thin zinc-rich compound cooperation, has stronger reproducibility, plays good antisepsis to body structural member, and provide inorganic fibre
Filler is tieed up, coating integral strength is improved；Water-borne base coat layer 2 realizes body color and metal effect, and vehicle body is made to have not
Same color, keeps it more beautiful；Water varnish layer 3 reaches excellent paint film property by isocyanate group cross-linking reaction, real
Existing vehicle body is smooth,
Bloom is plentiful, while providing the protection and decorative effect to sunlight, rainwater, branch or other scrapings etc..
Entire protective coating all uses environment protecting water-based paint, the discharge of VOC in application is greatly reduced, to environment
It is extremely friendly, and remove middle priming layer from, environmental protection and energy saving have far-reaching social effect.
A kind of performance technologies of the protective coating of this practical new body of a motor car water paint application check data：
