Typically, it is crosslinked to be based on the transesterify of carboxyl-functional and two-N-beta-hydroxy acid amides linking agent based on the powder coating of beta-hydroxy acid amides.Such powder is by being purchased

The type powder is illustrated.Embodiment 4 has shown the details of composition and based on the curing of the resin of biology and curing based on the resin of conventional oil chemical products.Such chemical action is insensitive to catalyzer, so the significant difference of solidification rate in not occurring expecting, and in fact, does not also find the advantage of any resin solidification speed in this kind situation.

These two kinds of coating were solidified 30 minutes down in two kinds of different temperature (121 ℃ and 147 ℃).Its maximum differential is the gloss under the comparatively high temps, promptly based on the gloss of the resin combination of biology than bright about 50 units of the gloss of control group.But, based on the solvent resistance of the composition of biology slightly a little less than.Significantly, when comparing, all has competitiveness based on the resin of the biology over-all properties in the crosslinked composition of beta-hydroxy acid amides with the control group that is purchased.

Hydridization powder coating: carboxylic acid-epoxy cross-linking

The powder coating of carboxylic acid-epoxy cross-linking is modal hybridization coating.Usually, these hybridization coatings comprise can with the polyester acid that prepare, petroleum derivation of acrylic acid epoxy linking agent.Synthetic carboxyl-functional of the present invention based on the resin of biology and in typical composition, comparing test with the polyester acid that is purchased based on petroleum chemicals.

When Fig. 4 A has shown 121 ℃, from this research based on the resin of biology and the analogous viscosity that typically is purchased resin (FINE-CLAD 8400) (with the pool expression) to 121 ℃ shearing rates.Noticeable biological resin (data point of the low group) viscosity that is based on is lower than its comparison (counterpart).

Given this viscosity differences possiblely is---under lower temperature, can provide better based on the material of biology and flow, thereby make the outward appearance of cold curing paint overall the improvement occur.The roughness average measurement value that described improvement can use various industrial processes to obtain is represented approx.

In embodiment 4A, with Clear coating surfaceness (R based on biology _a) definite value 1.3 compares, and will be decided to be 4.2 based on the surfaceness of the Clear coating of the control group of petroleum chemicals.The roughness of the plate of petroleum derivation and common sawing operation quite, and is and suitable based on the plate of biology and typical electronic bundle or laser operations.Composition based on biology more approaches " A level " surface smoothness than control group.

The powder coating and low temperature cured powder coating (the Forrest Powder Low Temperature that is purchased obtainable petroleum derivation that have prepared embodiment 4A based on biology

) plate of usefulness relatively.Spray two plates of the film thickness of about 2.5 mils, then in 121 ℃ of thermofixations 30 minutes.Show with contrasting based on the powdered material of biology and to compare still less tangerine peel (or surfaceness) with powder coating.In addition, the plate based on the powder coated of biology shows higher glossiness (72 minutes to 50 minutes) under 60 ℃.Detailed content referring to the composition of embodiment 4A.

The melt flow of the improvement of the composition that service stress control type rheometer measurement is biologically-derived.Powdered sample is placed between the platen that is heated to 100 ℃ and with it is compressed to the thickness (about 2 mils) of typical powder coating film.This temperature is risen to 121 ℃ and measure viscosity change (with pool expression) until this sample solidifies.Viscosity data is shown in Fig. 5.

The curve data point of top is represented correlated control group powdered sample, and the curve data point of below is represented the powdered sample based on biology.Be starkly lower than the sample (3694 pools are than 11980 pools) of control group based on the initial viscosity of the composition of biology.Along with time lapse, owing to sample solidifies makes the viscosity of two kinds of samples increase.Because the viscosity based on the composition of biology remains on lower level in remaining set time, thus such powder at film crosslinked and solidify before have higher fusing and mobile probability.

Snappiness (tolerance of roughness) is the coating attribute of a key, the use that it can withstand last finished product to follow coated object and the bump that takes place every day and fiercely attack.When bump took place, relatively poor snappiness caused coating cracking and makes coating be peeled off by substrate sometimes.When substrate out of doors, when using under chemical substance (as the acid rain) condition in the water, in uv irradiation, oxidation and the atmosphere, may performance degradation and film is become fragile.Multiple in these factors also can cause corrosion, and corrosion can cause gets rusty and make outward appearance and snappiness variation.

In the flexibility test that is called bending shaft (Mandrel Bend) (ASTM D522), and then the sample of control group discussed above and composition based on biology are compared.For this test, the substrate that applies sandwiched in the anchor clamps and around the cone axis surface rotate.Adhesive tape binding power test on this zone has been determined the final performance of coating.Tear to determine whether described coating still is attached to this plate with the bending area of described tape applications on coating and with this adhesive tape.

Cone axis has different width along its length, and is the narrowest for 3.18mm (1/8 inch)---and this is the minimum size that can be used for testing and is flexible size, peeling off or ftractureing of coating just can not occur after withstanding this size.

Coating based on biology has good snappiness, and it only has small crack and does not have and significantly peel off sign.The coating of the control group of petroleum derivation is about 40% of bending length along whole plate length cracking and the coating peeled off.Detailed content referring to the composition of embodiment 5.

If can remedy more low viscous words under the certain temperature by the surface of pigments excellent wetting capacity, then painted powder coating also can obtain some advantages based on the resin combination of biology.In embodiment 6, the composition of two kinds of black has been described, a kind of is control group and a kind of biology that is based on.

Under 60 ℃, compare with petroleum chemicals deutero-coating based on the powder coating of biology, have higher glossiness (85 proportions by subtraction 44 minutes).This may be once more owing to the good melt flow of composition during the thermofixation.

Use improves the colour developing/blackness of black pigment based on the composition of biology.Can determine described blackness by L and the b color component measured in the coating.(be used to explain Hunter color meter (Huntercolor Scale), referring to " Organic Coatings:Science and Technology ", second edition, Wicks, Z.W. etc., particularly 351-355 page or leaf, Wiley Interscience, NY, NY.ISBN0-471-24507-01999).

The total Delta E or the aberration of two black plates are 0.52, and wherein the composition based on biology is easier to colour developing (black).Because the black pigment of the plate of control group (left side) does not resemble based on the black pigment of the composition of biology and is dispensed in the vanish system fully, so the plate of control group (left side) demonstrates than based on the more grey color of the composition of biology.This may be owing to described based on the lower viscosity of the resin of biology.
