Description

A kind of antibacterial antistatic ultraviolet-curing paint and preparation method thereof
Technical field
The present invention relates to a kind of antibacterial antistatic ultraviolet-curing paint and preparation method thereof, belong to photo-cured coating field.
Background technology
Ultraviolet-curing paint is a kind of environmental protection and energy saving coating succeeded in developing in recent decades.It has the incomparable advantage of many traditional coatings: save the energy, capacity usage ratio is high; Solvent-free discharge, safety non-pollution; Curing speed is fast, and production efficiency is high; Can application to heat sensitive base material; Film quality is high, coating performance is excellent.Enter 21 century, people's environmental consciousness constantly strengthens, and more and more selects environmentfriendly products, and this Green Product will obtain larger development from now on.In the past few years, ultraviolet-curing paint has and develops very rapidly in fibre coating, CD coating/DVD tackiness agent, credit card, timber, beverages can, food product pack, journal surface, medicine equipment and automobile industry.Ultraviolet-curing paint has huge market potential.The coating material solidified first part of patent of UV-light (UV) was born in nineteen forty-seven, through the development of over half a century, UV is coating material solidified has become comparatively proven technique, and particularly along with the raising of people's environmental consciousness, production and researchist note the development and application that UV is coating material solidified more.
Antibiotic paint refers to a class functional paint that can stop bacterial growth or kill bacterium, is generally divided into addition type antibiotic paint and structure-type antibiotic paint.Addition type antibiotic paint is by adding the antiseptic-germicide with antibacterial, the obtained coating with antibacterial.Current antiseptic-germicide mainly contains the large class of natural antibacterial agent, organic antibacterial agent and inorganic antiseptic 3.Structure-type antibiotic paint is connected on macromolecule resin base-material by certain chemical bond by antibacterial group, with the antibiotic paint that this macromolecule resin base-material is obtained.
Static hazard results from electrostatic force and static sparking, and static discharge the most serious in static hazard causes the on fire of combustiblematerials and blast.Because the volume specific resistance of polymkeric substance is generally up to 10 10~ 10 20Ω/cm 2, easily put aside electrostatic and cause danger, and static inhibitor polyphyly tensio-active agent, can make frosting affinity moisture, ionogenic surfactant also has electric action, and electrostatic thus can be made to leak in time.
Coating increasing application in daily life, in order to adapt to different service requirementss, have developed the functional coating of different functions.The coating having several functions concurrently is the direction of future studies development.At present, have antistatic and coating that is anti-microbial property concurrently and not yet see relevant report, therefore in order to meet antibacterial and anlistatig demand simultaneously, develop a kind of coating having both functions concurrently, seem particularly necessity.
Summary of the invention

In aforementioned antibacterial antistatic ultraviolet-curing paint, base resin is unsaturated polyester resin 191, and activity diluting monomer is Dipentaerythritol Pentaacrylate and/or pentaerythritol triacrylate.
In aforementioned antibacterial antistatic ultraviolet-curing paint, light trigger is sulfo-propoxy-thioxanthone and/or isopropyl thioxanthone, and static inhibitor is stearyl trimethyl ammonium chloride, and fire retardant is tetrabromobutane or trioctyl phosphate, and antiseptic-germicide is zinc oxide.
In aforementioned antibacterial antistatic ultraviolet-curing paint, flow agent is organosilicon flow agent Tech-257N, defoamer is BYK-055 or BYK-057, described thickening material is one or more in polyacrylamide, polyvinyl alcohol or polyvinylpyrrolidone, photostabilizer is 2-(2 '-hydroxyl-5 '-aminomethyl phenyl) benzotriazole and N, N '-bis-(2,2,6,6-tetramethyl-piperidyl) hexanediamine.
The preparation method of antibacterial antistatic ultraviolet-curing paint, comprises the following steps: (1) takes base resin according to quantity and activity diluting monomer adds in reaction vessel, mixing ultrasonic disperse; (2) take light trigger, static inhibitor, fire retardant and antiseptic-germicide according to quantity, add in reaction vessel, warming while stirring to 110 DEG C, reaction 2 ~ 4h; (3) be cooled to 75 DEG C, add flow agent, defoamer, thickening material and photostabilizer according to quantity, reaction 1 ~ 3h, to obtain final product.
Further, preparation method comprises the following steps: (1) takes base resin according to quantity and activity diluting monomer adds in reaction vessel, mixing ultrasonic disperse 45min; (2) take light trigger, static inhibitor, fire retardant and antiseptic-germicide according to quantity, add in reaction vessel, warming while stirring to 110 DEG C, reaction 3.5h; (3) be cooled to 75 DEG C, add flow agent, defoamer, thickening material and photostabilizer according to quantity, reaction 2.5h, to obtain final product.
The light trigger used in the present invention, static inhibitor, fire retardant, antiseptic-germicide, flow agent, defoamer, thickening material and photostabilizer, wherein light trigger is one of important component of photocuring sizing agent, and it plays decisive role to solidification rate.Light trigger is by after UV-irradiation, and light absorbing energy, splits into 2 living radicals, initiating activity polymkeric substance and monomer generation chain reaction polymerization, in the present invention light trigger have fast, environmental protection and energy-conservation feature.
Static inhibitor: be the deleterious charge of gathering is guided/eliminated make it not bring inconvenience to production/life.The present invention selects stearyl trimethyl ammonium chloride to have the anti-static function of rapid long-acting.
Fire retardant: the functional aid giving combustible polymers flame retardancy, mainly for the Principle And Method of Flame Retardation Design of macromolecular material.Additive flame retardant joins in polymkeric substance by mechanical mix techniques, makes polymkeric substance have flame retardant resistance.Reactive flame retardant is then participate in polyreaction as a kind of monomer, and therefore make polymkeric substance itself containing flame-retardant composition, its advantage affects less on polymer materials use properties, and flame retardant resistance is lasting.
Antiseptic-germicide: refer to and can within a certain period of time, make the growth of certain micro-organisms (bacterium, fungi, yeast, algae and virus etc.) or breeding remain on chemical substance necessary below horizontal.
Flow agent: it can impel coating to form smooth, smooth, a uniform film in drying and forming-film process.
Defoamer: have antifoaming speed faster, but the bubble time is longer, Applicable media is wider, and even harsh media environment is as the feature of high temperature, strong acid and highly basic.
Thickening material: adding after thickening material can adjusting coating rheological, gives the physical mechanical stability that it is good.
Photostabilizer: UV light absorber can the UV-light of absorbing polymeric sensitivity consumingly, and can be that harmless form of thermal energy is released by energy conversion.Radical scavenger can catch the living radical generated in polymer, thus suppresses photo-oxidation process, reaches light and stablizes object.Both acting in conjunction energy barriers of combining or suppress photoredox or photo aging process.
Usefulness of the present invention is: a kind of antibacterial antistatic ultraviolet-curing paint provided by the invention and preparation method thereof, the gained paint solidification time is short, hardness is high, surface resistivity change after film-forming 24h and after three months is little, all there is higher surface resistivity, thus not easily accumulation electrostatic, embody good electrostatic-proof function; Also there is certain anti-microbial property, and it is to the suppression of bacterium, the longer time can be maintained, there is excellent flame retardant properties, can effectively for the combustible matl of coating provides obstruct protective effect; Preparation method of the present invention is simple, and mild condition is easy to control.
