Description

A kind of water nano composite coating material and its preparation method and application
Technical field
The present invention relates to a kind of water nano composite coating materials and its preparation method and application, belong to ink-jet printing technology Field.
Background technology
Realize that picture and text printing is an emerging research hotspot in three-dimensional object surface at present, domestic and international researcher is positive It conducts a research.Ink-jet technology have many characteristics, such as it is non-contact, without printing pressure, adaptable, be it in three-dimensional objects surface individual character Change printing and provides possibility.
But since the ingredient of three-dimensional objects is varied, and the ink of inkjet printing, it is either water base or oily Base, viscosity all very littles, mobility is all very big, and in air brushing forming process, ink can be in substrate surface stream after arriving at stock Dynamic, dip dyeing to the position of neighbouring ink droplet had both influenced color rendition quality or had influenced resolution ratio;Furthermore, it is possible to there is also The problems such as picture and text adhesive force caused by surface affinity difference is not good enough, image definition defect.Therefore it needs to increase on its surface Corresponding coating makes colour picture in colored vividness, saturation to improve the ink absorption and image appearance power of stock Degree, finely structured hierarchies, clarity, color rendition and color fastness are attained by good level.Used coating currently on the market Mostly fast-drying solvent type, with the rapid development of industry, more and more noticeable, people the problem of environmental pollution, ecological degeneration More and more stronger to the appealing of environmental protection, green science and technology has become the mainstream of scientific development, traditional solvent-based coating due to The discharge of volatile organic compounds (VOC) and hazardous air pollutants (HAP) severely exceeds can be gradually by environment-friendly type aqueous painting Layer is replaced.
Invention content
The purpose of the present invention is to provide one kind capable of shortening layer of ink surface drying time, and the excellent water nano of printing quality is multiple Close coating material and its preparation method and application.
In order to achieve the above objectives, the technological means that the present invention uses for:
A kind of water nano composite coating material, is made of the raw material of following parts by weight:100-132 parts of water-base resin, nothing 0-2 parts of 14-66 parts of machine Nano sol, 0-54 parts of white pigment, 2-4 parts of macromolecule dispersing agent and auxiliary agent.
Preferably, the water-base resin is waterborne polyurethane resin, water-based acrylic resin, aqueous acrylic modified poly- ammonia At least one of ester resin.
Preferably, the inorganic nano colloidal sol be water-based nano silicon dioxide alkaline sol, grain size 10-30nm, than Surface area is 200-300m2/g。
Preferably, the ingredient of the white pigment includes nano-titanium dioxide.
Preferably, the macromolecule dispersing agent is polyvinylpyrrolidone (PVP), polyethylene glycol -200 (PEG-200), gathers At least one of ethylene glycol -400 (PEG-400).
Preferably, the auxiliary agent is at least one of antifoaming agent, preservative and rheological agent.
Preferably, the grain size of the water-base resin, inorganic nano colloidal sol, white pigment, macromolecule dispersing agent and auxiliary agent is equal Within 500nm.
The present invention also provides a kind of methods preparing the water nano composite coating material, include the following steps: Water-base resin is added in beaker, the water that the 0.5-30% of water-base resin gross mass is added is diluted stirring, at the same time Inorganic nano colloidal sol, macromolecule dispersing agent is added, adjusts pH value to 7-9, continues to stir, obtain pre-emulsion, by the pre-emulsion into It is shaken, is filtered to get water nano composite coating material after row grinding.
Preferably, further include that white pigment is added and helps while inorganic nano colloidal sol, macromolecule dispersing agent is added The step of agent.
The present invention water nano composite coating material be applied to inkjet printing in, can be used for 3D printing material (including PLA, ABS, PMMA, photosensitive resin), the material surfaces such as wood materials and leather.
Compared with the existing technology, the beneficial effects of the present invention are:
Since resin used in water nano composite coating material of the present invention contains stronger polar group-NCO ,-OH, urea groups Deng, and intermolecular formation hydrogen bond, there is higher cohesive force, and inorganic nano sol particles used have porosity and print to Substrate surface can quickly absorb by itself intrinsic capillary force between particle and accommodate the moisture in ink droplet after forming coating, Layer of ink surface drying time and excellent printing quality can be shortened.It is according to the invention to be formulated aqueous receiving of being prepared Rice composite coating material VOC content is less than 200g/L, prints colored picture and text again after being printed to stock surface, can improve The adhesive force and glossiness of layer of ink.
