Description
Technical Field
The invention relates to the technical field of preparation of thermosetting polymer aqueous dispersions, and particularly relates to a thermosetting polymer aqueous dispersion and a preparation method and application thereof.
Background
Coatings prepared from aqueous dispersions of polymer particles may be deficient in gloss, durability, and hardness development compared to coatings prepared from solvent-based polymers. Dispersions comprising a blend of different aqueous polymer dispersions (e.g., a blend of an acrylic dispersion and a polyurethane dispersion, or a blend of an acrylic dispersion and an epoxy dispersion) are known to improve coating properties; blends in the wet state, however, can exhibit storage instability and are limited to solids. In addition, coatings derived from these blends can exhibit performance problems due to latex incompatibility and polymer back mixing. In addition, dispersions obtained by the simple polymerization of polyurethane and acrylic monomers by covalent bonding reactions are generally only suitable for single components. When curing by crosslinking as a two-component, it is generally necessary to use polyethylenimine as a crosslinking agent, but such crosslinking agents are highly toxic.
Patent CN102786759A proposes a method of mixing epoxy resin and aqueous acrylic acid by absorbing latex particles with thermoplastic polymer, which can introduce epoxy group into thermoplastic aqueous acrylic acid emulsion, and further can react with common amine curing agent to improve its physicochemical properties. However, the epoxy group is not introduced into the waterborne acrylic polymer in a covalent bond reaction mode, and when the amine curing agent is used for curing to prepare a two-component coating, the selectivity to the amine curing agent is high due to the difference of film forming speeds of acrylic acid and epoxy.

And (3) performance testing:
1. colloidal stability was evaluated. The samples were placed in an oven at 60 degrees celsius for 10 days to determine heat aging stability. The weight average particle size was measured by laser light scattering. The test results are shown in table 1.
2. Testing of the properties of metallic paints prepared using aqueous polymer dispersions:
the formulations of the aqueous metallic paints of the comparative examples are shown in Table 2, and part A was prepared by milling using a Kohler disperser to obtain a fineness rating of Hegman 7 +. Part B was configured using a bench mixer. Viscosity was measured using a stormer viscometer. Part B was then added to part a and stirred for 15 minutes at which time the stormer viscosity of the paint formulation was measured.
The formulation of the water-based metallic paint of the example is based on the table 2, after mixing the components A and B, 0.51 g MXDA is added as the third component amine curing agent for the cross-linking reaction with the water-based dispersion containing glycidyl ether group synthesized in the example.
The gloss, hardness and impact properties of the examples are listed in table 3. Gloss was determined according to test method ASTM D-523-89. The above formulation was applied to a treated aluminum substrate at a wet film thickness of 10 microns, following test method astm d-823-95 procedure E, to give a dry film thickness of about 2 microns. The coatings were tested for 20, 60 and 85 degrees gloss after one week of drying/curing at ambient temperature and 50% relative humidity. The hardness of the swing rod is tested on the same panel by using a test method ASTMD4366-95 and by adopting amplitude limitation of 6-3 ℃ and oscillation time of 1.4 seconds. After curing/drying for 2 weeks at ambient temperature and 50% relative humidity, pencil hardness was determined according to test method astm d3363-05 using the same plates as the gloss test.
After drying/curing the coating for one week at ambient temperature and 50% relative humidity, the treated aluminum panels were knife-coated for chemical resistance in the gloss test (spot test). The test was carried out as follows: the round fiber disc was saturated with different chemicals, placed on the coating and covered with a lid. During the soaking process, the lid is opened and the panel is wiped with a wipe. The following ranges were used to represent the degree of damage to the paint film and the coatings were rated: 1-undamaged, 2-slightly swollen, foamed or wrinkled, dull, yellow, 3-moderately swollen, foamed or wrinkled, 4-severely swollen, foamed or wrinkled, 5-dissolved, delaminated. The ratings and mean values for the individual chemicals are listed in table 4.
The corrosion resistance was tested by exposing the panels to a salt spray environment (5% sodium chloride mist) according to test method astm b-117-97. The panels were prepared by the following method: paint was drawn on 10-cm x 30-cm grit blasted hot and cold rolled steel panels and dried at 24 degrees celsius at 50% relative humidity for 2 weeks to give a final dry film thickness of 2 microns of coating. Bare metal was covered with 3M tape #471 before the salt spray test. A scratch mark is scribed on the bottom half of the panel. Periodic removal of the panels rated for rust and air bubbles. The blister rating is performed according to test method astm d714-87 and is reported as a number and one or more letters, V is the dense density, M is the medium density, and L is the small density. Rust rating is expressed as percentage of rust on the panel. The test results are shown in table 5.
