Abstract
The invention discloses water-based ink-regulating oil and a preparation method and application thereof, wherein the preparation raw materials comprise the following components in parts by weight: 1 to 10 parts of phosphate modified acrylic resin, 0.5 to 5 parts of thickener, 1 to 2 parts of dispersant and 80 to 95 parts of solvent; the preparation raw materials of the phosphate modified acrylic resin comprise: phosphate functional monomers, methoxypolyethylene glycol acrylate, acrylic acid and acrylate; the phosphate functional monomer comprises at least one of methacrylic acid acyloxyethyl phosphate, ethylene glycol methacrylate phosphate, alkyl acrylate phosphate, allyl polyether phosphate and methacrylic acid polyether phosphate; the weight average molecular weight of the phosphate modified acrylic resin is 5000-100000 MW. The environment-friendly water-based ink varnish prepared from the phosphate modified acrylate resin has low smell, is environment-friendly, has little ash content after high-temperature sintering, has little carbon residue, and has little influence on the color of a glaze layer.
Description
Technical Field
The invention belongs to the technical field of ink, and particularly relates to water-based ink-regulating oil, and a preparation method and application thereof.
Background
The existing photovoltaic glass high-reflection ink is generally prepared from low-melting-point glass powder, titanium dioxide, ink-regulating oil and the like, wherein the content of the powder is up to more than 70%. The ink-regulating oil, also called as scraping plate oil (binder), is an important component of printing ink, and the rheological property, viscosity, drying property, film forming property, printing property and the like of the ink depend on the ink-regulating oil, and is the key of the quality of the ink. The main components of the glass screen printing ink are various organic resins, high boiling point organic solvents and auxiliary agents, and the glass screen printing ink mainly has the functions of mixing powdery low-melting glass powder, titanium pigment and other pigment fillers into paste so as to facilitate screen printing, and the glass powder and the titanium pigment can be temporarily adhered to the surface of a smooth glass product by means of the viscosity of the glass powder and the titanium pigment, and the glass powder and the titanium pigment must be completely volatilized and burnt in the high-temperature decoration firing (firing) process. The sintering process of the high-reflection printing ink for the photovoltaic glass is generally carried out at 680-750 ℃ for 2-6 min, the softening point of the low-melting glass powder for the high-reflection printing ink for the photovoltaic glass is generally between 450-600 ℃, the resin is rapidly decomposed at high temperature during glass tempering, and meanwhile, the low-melting glass powder is melted and softened to replace the resin as a binder to form an enamel body, so that the printing ink is converted from organic bonding to inorganic bonding and firmly bonded with the glass. In order to obtain good sintering properties (high reflection and ink layer compactness) and acid resistance, it is desirable that the resin and the low melting glass frit have good matching properties, i.e., to ensure that the low melting glass frit starts to melt flow when the resin decomposition is completed. Therefore, it is required that the final decomposition temperature of the resin and the softening point of the low melting glass frit are not greatly different; meanwhile, the softening point and crystallization temperature of the low-melting-point glass powder are required to be lower than the sintering temperature, so that the ink can be fully melted, flowed and spread into a compact surface layer during sintering, and the surface layer is crystallized to achieve better reflectivity and weather resistance. The problem of matching between the decomposition temperature of the varnish resin and the melting temperature of the selected low-melting-point glass powder and the temperature of a tempering furnace is required, the varnish cannot be decomposed prematurely, the ink layer is easy to pulverize and fall off due to the fact that the glass powder is not melted in the early decomposition process, the varnish cannot be decomposed too late, organic matters cannot be decomposed completely due to the fact that glass liquid melted by the glass powder covers and wraps the varnish in the late decomposition process, and the colored glaze is coked and blackened. In addition, for the ink with high powder content, the ink-preparing oil resin is also required to have excellent wetting and dispersing ability on powder, so that the surface of the powder is rapidly wetted and wrapped and the powder is quickly opened after penetrating into the powder, the powder dispersing and grinding efficiency is improved, the powder dispersing particle size is small, meanwhile, the agglomeration of the powder can be prevented, and the inorganic powder is easy to settle and delaminate, so that the storage stability and printing adaptability of the ink are affected.
In the prior art, the introduction of the organic silicon can reduce the surface energy and increase the wettability of resin to glass powder and titanium pigment, but the introduction of the organic silicon and styrene can also cause the decomposition temperature of the resin to be increased, so that the white high-reflection glaze layer is easy to cause higher carbon residue after sintering, and the color of the glaze layer is blacker; meanwhile, mass production data show that the introduction of the organic silicon easily causes 'white fog' in the toughening furnace, namely, the organic silicon is gasified to form fumed silica which is adhered to the upper cavity of the toughening furnace and the conveying roller, and the furnace needs to be shut down frequently for cleaning, so that the production efficiency is affected.
In summary, developing an aqueous ink-transfer oil with less residual carbon after high-temperature sintering is a difficult problem that researchers in the field need to explore.
