The AMP-95 of department, thickener are the RM-8W and RM-12W of the Dow Chemical Company, and wetting agent is the GLIDE440 of goldschmidt chemical corporation.
The most crucial technological difficulties of the present invention are：Water-based stoving paint is mainly solved for white background baking vanish in bicycle
Rust-preventing characteristic, tear resistance, impact resistance on metal substrate and good mating with finishing coat.
The application is compounded using aqueous polyurethane resin emulsion and high Tg monocomponent self-cross-linking emulsion acrylic resin, collocation
Suitable amino resins reaches the technical requirements of bicycle use metal white background water-based stoving paint.
Aqueous polyurethane resin emulsion is usually synthesized by the soft pure and mild polyisocyanates of polymer polyol, wherein polymer
Polyalcohol constitutes the soft segment of polyurethane resin molecular structure, and polyisocyanates constitutes the hard section of polyurethane resin molecular structure.It is poly-
The soft segment of object polyalcohol is closed, molecule segment is very soft, and cohesive energy is very low, is easy to produce deformation, internally plasticized effect is generated, so that
Ester-polyurethane resin emulsion has excellent filming performance, even if being also such under low-temperature condition.Polyaminoester emulsion particle is one
The water-swellable type structure of a opening, water have stronger deformation and softening power to latex particle, can after polyurethane particulate swelling
Cause the surface area of particle to become very big, so that it is easily deformed and is formed a film, and system viscosity can comparatively fast increase, so as to have
Effect is riveted ground, pigments and fillers and various components, improves in paint film drying process due to high Tg monocomponent self-cross-linking acrylic resin
The trend that the various phases of the inconsistent and solvent volatilization inconsistent appearance of dissolving power of lotion diffusion crosslinking rate separate.And it is appropriate
The addition of hydrophilic solvent can more obviously reach this effect, so as to improve quality of forming film, reduce difficulty of construction.
The above-mentioned micrograined texture and characteristic of ester-polyurethane resin emulsion can make up high Tg monocomponent self-cross-linking acrylic resin
The linear structure of lotion and the defect for crossing multiple stiffness hard segment, collocation can significantly improve high Tg one pack system using polyaminoester emulsion
Self-crosslinking acrylic resin emulsion film forming and workability, the additional amount of ester-polyurethane resin emulsion reach certain level, Ke Yiming
It is aobvious to improve cissing, floating, tangerine line, whiten, the construction problems such as difficult infiltration and understood due to the raising of system entirety quality of forming film
The dependence to environment is reduced, the fluctuation of final painting quality is effectively improved.Since the two phase structure of polyurethane material assigns
The unique performance of polyurethane, hard segment domains play the role of physical crosslinking point in the material.Hard segment domains have biggish cohesion
Can, intermolecular force is stronger, conventional mechanicals efforts and at a temperature of, molecule segment is not allowed to be also easy to produce sliding, therefore firmly
Duan Weiqu plays the role of similar chemical crosslinking, can all have a major impact to tensile strength of material, hardness, temperature denaturation.Here it is
Even if polyaminoester emulsion is not chemically crosslinked, the reason of high intensity, high rigidity, highly resistance are after-tacked can be also shown under room temperature.Hard section
Phase region softening melting temperature also with higher, as long as hard section phase region is not melt thawing, material can show opposite
Thermal stability, material is not in deformation or surfaces of tacky, to show excellent anti-after tack.
Monocomponent self-cross-linking acrylic emulsion filming performance can be significantly improved additionally, due to ester-polyurethane resin emulsion, therefore
Slow curing film forming solvent in formula can largely reduce addition, can reduce solvent and accumulate in film, further improve the paint at initial stage
The anti-after tack of film.The above structure and characteristic of polyurethane can largely reduce high Tg monocomponent self-cross-linking emulsion acrylic resin
The addition of film forming solvent in system, and the temperature that can improve its linear molecular structure property becomes sensibility, to obtain excellent
Anti- after tack.Will form strong hydrogen bond in polyurethane material, between carbamate key and carbamate key and its
Its group can form hydrogen bond, and the formation of hydrogen bond is the structure root that polyurethane has outstanding wearability.Though active force between hydrogen bond
So big but more much bigger than intermolecular Van der Waals force without chemical bond power, hydrogen bond action can increase substantially polyurethane material
Cohesion energy density, obtain splendid wearability, polyurethane is referred to as " wear-resisting king " due to the feature.In addition polyurethane material
The hard phase microcell of material can assign the high mechanical force of material and thermodynamic (al) stability, show high intensity, high rigidity, highly resistance and after-tack
Characteristic, soft phase microcell assigns material fabulous elasticity, pliability and cryogenic property.These characteristics will lead to polyurethane material
Obviously good flexibility is shown compared to monocomponent self-cross-linking acrylic emulsion.Therefore the addition of polyaminoester emulsion can be obviously improved
The flexibility of high Tg self-crosslinking acrylic emulsion system improves paint film intensity, the cohesion energy density of material is greatly improved, to change
Kind paint film wearability.
The method have the benefit that：This is used for the metal white background water-based stoving paint of bicycle coating with aqueous polyurethane
Resin emulsion, high Tg monocomponent self-cross-linking emulsion acrylic resin and amino resins are main component, add titanium dioxide, flatting silica
It is white pigments and fillers with talcum powder, and is aided with hydrophilic solvent, other auxiliary agents and goes from from water, wherein waterborne polyurethane resin is newborn
Liquid is that polyhydroxy blocks aqueous polyurethane resin emulsion, hydroxyl value 40-120mgKOH/g, and solid content as 50~60wt.%；
Wherein in high Tg monocomponent self-cross-linking emulsion acrylic resin acrylic resin Tg be 50~60 DEG C, and solid content be 40~
55wt.%；Wherein amino resins is at least one of full Amino resin or part Amino resin, passes through tune
The parameter and dosage of whole each component substance, obtained metal white background water-based stoving paint have good adhesive force, rust-preventing characteristic, wear-resisting
Power, impact resistance, and it is good with the ability to provide the auxiliary items of finishing coat, construction tolerance is wide, product utilization rate is high, Environmental Safety.
