Coating crosslinking agent for solvent
The coating is widely used in the fields of architectural decoration, industrial painting, corrosion protection, woodblock painting, printing, etc., which are indispensable in People's Daily life. Due to the coating contains a lot of organic volatile solvent, and the volatilization of organic matter is not only a huge waste of resources, but also pollute the environment, endanger human body health, damage the ecological environment.
In view of this, there is a growing clamour for environmental protection, and a set of rules to limit the emissions of VOC in coatings. Therefore, the coating of the solvent is faced with an unprecedented test, the severe challenge of water-based coating, and the tendency to be replaced by water-based coating.
In recent years, with the improvement of material living standard, people have raised higher requirements for the environmental protection problem in home decoration, and the water based wood lacquer is also born. With the improvement of the performance of water-borne wood, it will gradually replace traditional solvent products.
The application of water-based paint on wood floor coating is the most common in northern Europe, it has reached 80 % of floor coating. The demand for water-based wood lacquer is expected to grow by 7% over the next few years. However, the water-based wood lacquer is still the hardness, the water resistance is not enough, the problem of the problem such as poor fullness and high temperature return.
As a result of water-based paint to introduce a large number of hydrophilic group and the difference with solvent-based coating film-forming mechanism, makes compared with the same or similar molecular structure, solvent coating, waterborne coating is hard to exceed its performance. Now, the pencil hardness of water-based paint products in the market can be used very little by 2H, these are the main points of further study of water-based wood lacquer.

To this end, this paper USES ethyl methacrylate acetyl acetoxyl group (A b E M) as crosslinking monomer, synthesis temperature self crosslinking emulsion, waterborne wood paint are using self crosslinking technology to solve exist enough hardness, water resistance and high temperature back stick, has important theoretical and practical significance.
Experiment reagent and instrument, methyl methacrylate (M M A), butyl acrylate (n - A, B), acrylic acid (AA) and acrylic acid isooctyl ester (2 - EHA) are chemically pure, above monomers by vacuum distillation after stored in the refrigerator spare; Methacrylate acetyl acetylacetylacetylmethyleate (AAEM) is an industrial product; 1, 6 - hexadiamine (HDA) for pure analysis; Sodium lauryl sulfate (S D) is chemically pure; Polyethylene glycol octyl ether (OP -20) is chemically pure; And NaHCO3 is pure; Ammonium persulfate (A P S) is pure analysis.
To the emulsion, after besmear is on glass slide film in infrared spectrometer (Bruka Vector and Spectrophotometer, Germany) on infrared spectrometry; Emulsion will be diluted 400 times after the drop in copper coated carbon film online, negative staining with phosphotungstic acid first, and then in the tem (JEM - 1200 ex, Japan Electronics) on observing the morphology and size of latex particles; Bibulous rate is in accordance with the national standard GB 1733-79 test, water resistance according to GB/T 1733-93 test, pencil hardness test according to GB/T 6739-6739, on the basis of film cut.
Using the differential scanner (Perkin Elmer Instruments Pyris 1) determine the Tg, polymer test temperature range for - 40 ℃ ~ 100 ℃, the heating rate of 20 ℃ / min, the nitrogen atmosphere.
Emulsion will be diluted to mass fraction is 20% solid content, into the size of 90 mm x 90 mm x 6 mm of ptfe mold, drying at room temperature (25 ℃) to film the crosslinking density of no longer changes, then according to the national standard GB/T 16421-1996 film cut into type II dumbbell specimens, and in 2000-10 RG microcomputer control electronic universal test machine to determine the tensile strength of the coating. In accordance with the literature [4, 5], using the solubility test network chain density ve (mol/cm3).
