The thermosetting organic coloring printing ink and the marble paper that are used for decorating silicate and metal base
Technical field
The invention belongs to coloring printing ink and decorate the marble paper technical field, especially relate to a kind of thermosetting organic coloring printing ink for decorating silicate and metal base and marble paper.
Background technology
The decoration of pottery and glasswork normally utilizes screen printing technique at substrate surface bedye ink logo.Then, at high temperature curing glass combines pattern picture and glass surface fully.This process shows its weak point sometimes.From the angle of environment protection, ink ingredient contains heavy metal, is unfavorable for environment protection.Secondly, this is crossed range request and uses high temperature oven to cure, and can expend mass energy like this.
Summary of the invention
The low-temperature curing marble paper that provides a kind of formation can be widely used in the silicate base material is provided one of purpose of the present invention, solves the defective that prior art exists.Described silicate base material generally includes pottery, glass and other silicate material, and certainly, low-temperature curing marble paper of the present invention is decorated at the metallic substance base material, also can play good effect.
Described marble paper comprises supporting structure, the peelable mask layer on patterned layer and the patterned layer; Described patterned layer is that the thermoset coloring printing ink forms, and described thermoset coloring printing ink comprises: the Resins, epoxy of 20~30wt%, the linking agent of 20~30wt%, the pigment dyestuff of 10~30wt%, the solvent of 20~38wt%, and 0.01~0.5wt% auxiliary agent; Described component sum is 100%.When be used for decorating, can by directly or indirect screen printing to base material to be decorated.Among the present invention, patterned layer is made of printing ink, and printing ink contains the granular pigments in the epoxide resin type mixture that consists of patterned layer.In the patterned layer, the quantity of pigment is than scope approximately from 10% to 30%, and the preferred weight ratio is approximately 25% to approximately 30% of patterned layer.Contain the quantity of prescription (selectively comprising linking agent, solvent and levelling agent) of Resins, epoxy than from approximately 90% to 60%, preferred weight ratio is approximately 75% to approximately 65%.
For meeting the peelable marble paper of water, can precipitate a water-soluble coating at general ceramic support paper; Such a paper coating is one and contains water-soluble gluey thing, for example dextrin, polyvinyl alcohol, starch or be similar to such material.
When being attached to peelable marble paper on the decorated vessel, whole marble paper is soaked in water, and functional layer slides from supporting paper very simply, then is attached to decorated vessel surface.The ink printing layer is close to vessel surface, and patterned layer and clear coat double exposure are on printed layers.
Two of purpose of the present invention is to provide a kind of coloring printing ink, this printing ink is mainly used in forming the patterned layer of the described marble paper of one of goal of the invention, the Resins, epoxy that comprises 20~30wt%, the linking agent of 20~30wt%, the pigment dyestuff of 10~30wt%, the solvent of 20~38wt%, and 0.01~0.5wt% auxiliary agent; Described component sum is 100%.
Preferably: described Resins, epoxy is bisphenol A type epoxy resin, perhaps bisphenol f type epoxy resin, perhaps the two mixture; Described linking agent is aliphatic polyisocyante, perhaps the aliphatic epoxy polyisocyanates.Ring grease chemical combination Polyurethanes (cycloaliphatic polyisocyanate) the VESTANAT B 1358A (trade mark Degussa) that linking agent preferably seals, be used as 63% solution in the trimethylbenzene solvent (for example, Solvesso 100); Can also use and contain the linking agent that any epoxy group well-known and that can make Resins, epoxy is cross-linked with each other.
More optimizedly: described pigment dyestuff is one or more combinations in azoic dyestuff, dispersed dyestuff, perylene dyes, triphenylmethane dye, vat dyes, fluorescence dye, phthalocyanine and the carbon black pigment.The weight ratio scope of preferred tinting material can be 15wt% to 30wt%.Add suchlike pigment and make printed layers reach the opaque effect of expectation, and therefore just can reach the contrast effect of expection in ink printing layer seal patterned layer.
More optimizedly: the molecular weight of described Resins, epoxy is 4000~30000.Useful especially epoxy polymer is that trade mark is a kind of low-molecular-weight epoxy polymer of " EPIKOTE ", can obtain this material from HEXION SPECIALTYCHEMICALS company; Also adaptable other epoxide resin material comprises the RUETAPOX that Bakelite produces.Resin can be dissolved in the solids content scope approximately 25% to the about solvent between 50%, Dipropylenglykolmonomethylether for example, Monopropylenglykolmonomethylether, Propylenglykolmethyletheracetat waits suchlike material.Prescription that has much advantage is included in the mixture of above-mentioned solvent and contains 34% resin solution.
More optimizedly, described auxiliary agent is wetting agent or dispersion agent, described wetting agent or dispersion agent are the alkyl ammonia salts solution of anionic/nonionic characteristic high molecular polymer, described solvent is methoxyacetic acid n-propyl (Methoxypropylacetate), perhaps propylene glycol (Propyleneglycol), perhaps one or several mixtures in the methoxypropanol (Methoxypropanol).Wetting agent and dispersion agent have improved the wettability of pigment, have shortened the required time of process of lapping, and have stablized the dispersing property of pigment.Avoid loose colour and grow diming phenomenon, improved glossiness.
More optimizedly: the shared weight fraction of described wetting agent or dispersion agent is 0.05wt%~0.5wt%.
The present invention compared with prior art has following advantage and beneficial effect.
A kind of novel marble paper provided by the invention just can be fixed on for example pottery, glass and other silicate, the vessel surface such as metal such as aluminium under the low-temperature heat treatment condition.The operating process that the low temperature marble paper is transferred on the object from prop carrier is at room temperature carried out, greatly facilitated operation; When marble paper being shifted and be fixed to body surface, guarantee that the character of each layer of low temperature marble paper self remains unchanged simultaneously.
Marble paper of the present invention, utilize a kind of thermosetting resin of similar epoxide resin material, it can be combined with the linking agent of some amount and generate a kind of compound, after 160 ℃ approximately Celsius extremely approximately 200 ℃ of so simple low-temperature curings are processed, just can play gratifying effect of being combined with vessel surface.
Marble paper of the present invention by two necessity but not identical level and support base stock and consist of.Two-layer separately every layer comprise respectively supporting structure, peelable mask layer on patterned layer and the patterned layer, be transferred to vessel surface by the design that supports on the paper marble paper, normally directly precipitation or the printing technology of logical coating form such as silk screen printing to support base stock.The linking agent that contains low-molecular-weight epoxy resin and some amount when patterned layer, masked isocyanate for example, after the low temperature baking was burnt, marble paper just can be soon and is fixed on easily article surface.
