Abstract
The invention provides a grainy topcoat used in color plate surface coating, and a preparation method thereof. The invention belongs to the technical field of paints. The topcoat assists in ameliorating a problem of steel surface decoration effect. The grainy topcoat is characterized in comprising the substances of, by weight: 45-55 parts of SK-ES410 saturated polyester resin, 8-11 parts of CYTEC303 amino resin, 30-35 parts of a pigment, 0.3-1.0 parts of a BYK110 dispersing agent, 0.5-1.2 parts of a BYK354 leveling agent, 5-10 parts of a solvent, and 0.3-1 parts of a KING N-5225 catalyst. The substances are blended and grinded, such that the topcoat is obtained. According to the topcoat provided by the invention, a formula is optimized, paint film surface state is changed, product application time is prolonged, and color plate surface coating quality is improved. As a result of tests, various indexes of the product are better than existing products, product service life is greatly improved, and product colors are enriched.
Description
Technical field
The present invention relates to a kind of coil coating, particularly a kind of for producing the finish paint that similar grained face effect can effectively increase the service life, enrich product color behind the colored steel external coating, belong to the paint technical field.
Background technology
The colored steel finish paint namely at galvanized sheet external coating paint, also claims coiled material finishing paint, is a kind of for the galvanized sheet external coating, plays the paint of decoration and provide protection.It namely requires with priming paint good sticking power is arranged, and can beautify again the Product Visual effect and can also protect ground not to be subjected to the factor affecting such as environment duration of service.The present employed finish paint of coil coating, following several raw materials of the general employing of its prescription: common saturated polyester, common aminoresin, pigment, auxiliary agent, solvent.Coil coating production technique routinely after the above-mentioned starting material batching processes through operations such as dispersion, grinding, paint, cans.The deficiency of this lacquer is: 1, paint film appearance is simple, without stereoscopic sensation; 2, duration of service short, weathering resistance is poor, color is single; 3, solid part is low in the prescription, and the VOC discharging is higher, unfavorable environmental protection.
Summary of the invention
The object of the invention is to overcome above-mentioned prior art not enough, provide a kind of paint film appearance effective, weathering resistance is good, reduces the VOC discharging, and environmentally friendly coiled material is with finish paint and preparation method.
Problem of the present invention is solved by following technical scheme: a kind of colored steel top coat grained finish paint is characterized in that it is comprised of the material of following weight unit: SK-ES410 saturated polyester resin 45-55, CYTEC303 aminoresin 8-11, pigment 30-35, BYK110 dispersion agent 0.3-1.0, BYK354 flow agent 0.5-1.2, solvent 5-10, KING Jin Shi N-5225 catalyzer 0.3-1.
Above-mentioned coiled material grained finish paint, it is comprised of the material of following weight unit: SK-ES410 saturated polyester resin 50, CYTEC303 aminoresin 8, pigment 32, BYK110 dispersion agent 0.5, BYK354 flow agent 1, solvent 8, KING Jin Shi N-5225 catalyzer 0.5.
Above-mentioned coiled material grained finish paint, described solvent by weight unit consists of: 1-Methoxy-2-propyl acetate (trade name PMA) 10-20, propyl carbinol 10-20, dibasic ester (trade name DBE) 5-20, petroleum solvent 100#50-60.
Above-mentioned coiled material grained finish paint, described solvent by weight unit consists of: 1-Methoxy-2-propyl acetate (trade name PMA) 15, propyl carbinol 10, dibasic ester (trade name DBE) 15, petroleum solvent 100# 60.
Above-mentioned coiled material is as follows with the preparation method of grained finish paint:
The first step: take by weighing each raw material for standby by proportioning;
Second step: get first the SK-ES410 saturated polyester resin, add the BYK110 dispersion agent and stir at dispersion machine, add while stirring pigment and solvent, 1000-1500 rev/min of lower high-speed stirring 30 minutes, the solution for standby that obtains;
The 3rd the step: mentioned solution is ground twice at sand mill, to fineness less than 15 microns dischargings;
The 4th step: add while stirring other raw material after the solution cooling, stirring gets product.
Product of the present invention improves for the deficiency of existing coil coating, the high weather-proof saturated polyester resin of its formula optimization and high stability aminoresin are as matrix resin, and be equipped with closure acid and adjust the drying varniss time, guarantee product stock stability, add mill base and adjust the coating surface color, enrich the visual effect of coil coating.Solid is high in the prescription, and noxious gas emission is few when dry, can reduce topsoil.After product of the present invention is used in the coiled material surface application, can prolong colored steel duration of service, enrich visual effect.Through check, this product is curved at sticking power, shock strength, pencil hardness, T, the index of cupping, anti-solvent (MEK) property, the aspect such as ageing-resistant all is better than currently available products.
After testing, the technical indicator of product of the present invention, paint film property and parameter comparison parameter see Table one, table two, table three:
