Abstract
A high wear resistance and static-free antibiosis paint relates to an oil paint and takes natural resin or synthesis resin as the base; pigment, filler, four-footed zinc oxide T-ZnO crystal whisker treated with dispersion and coupling, charging material and addition agent and solvent are then added, finally the paint is manufactured by mechanical processing; the isotacticity of the crystal whisker is more than 90 percent, the foot length-diameter ratio of the T-ZnO crystal whisker is 16-20, the foot length is 40-50 Mum and the consumption of the T-ZnO crystal whisker accounts for 0.5-5 percent of the total weight of paint. Compared with corresponding similar paints, the paint has simple and unique preparation process, excellent quality, stronger adherence, outstanding anticorrosive performance and mechanical property and preparation cost not more than the corresponding paint.
Description
Technical field
The present invention relates to a kind of oil paint, particularly relate to a kind of high abrasion, anti static antibacterial coating.
Background technology
The common traditional paint (oil paint) in market is that natural resin or synthetic resins are base-material, adds various pigment, various filler, auxiliary agent solvent again and forms through the mechanical workout manufacturing.Some resin wear no resistance and there is friction in some in environment for use, use and usually to cause the paint film wearing and tearing, and lose function; On the other hand,, in dry environment, usually can produce static, bring bigger harm because of macromolecular material mostly is the insulativity material, in addition dangerous; Because of can causing the enzyme flora of paint film, environment hygrothermal environment etc. gives birth to again.
Oil paint be used for more mechanical means and metal products/member and pipeline ,/protection and the decoration of road surface and woodenware or the like, in use can produce the motion friction and bear the impact of different media.Coating surface can cause wearing and tearing, come off being subjected to secular friction and impact, and loses protection and decoration to base material, influences its quality and life-span.Sometimes the reparation difficulty on its surface can very big (as inner-walls of duct etc.), and its expense is very high.
At present, being used to improve coating wear resistance major technique has:
(1) add mineral filler: hardness by improving coating and/or oilness to be improving its wear resistance, as: the application aluminum oxide micro-sphere (Al of description among the JP63227672 " Abrasion-resistant coating compositions containing alumina spheres " etc.s
2O
3); Mineral fillers such as usefulness molybdenumdisulphide, aluminum oxide such as Yang Jun prepare high abrasion epoxypaint " development of E-20 Resins, epoxy wear-resistant paint " (Chinese coating .2006, (3): 27-29); People such as Ma Haihua are in " research and development of wearing composite material coating " (Materials Science and Engineering .1995,13 (2): 34-37) introduced the influence to the epoxy coating wear resistance of titanium oxide, stannic oxide, ferric oxide, chromic oxide and corundum in the literary composition; Improve the hardness and the oilness of coating among the CN1687256A " a kind of corrosion-resistant abrasion coating " simultaneously with fluoro-resin and ceramic, to improve its wear resistance.
(2) modification of film-forming resin: as: the wear resistance " preparation of modified epoxy coating and performance study " of human base polyurethane prepolymer for use as modified epoxy coating such as Zhang Wei (Shanghai coating .2002,42 (3): 4-7); Human thiorubber modifications such as Shen Lixia have prepared wear-resistant paint " development of modified epoxy coating and application " (Sichuan chemical industry and corrosion control .2002,3 (5) 18-20).
(3) hybrid inorganic-organic, the wear-resistant paint that promptly prepares hybrid inorganic-organic by sol-gel process, as: usefulness silica gel and siloxanes cohydrolysis and polycondensation that EP604677-1994 " Silica-contaning siloxane-coated shaped articles and theirmanufacture " describes, the wear-resistant paint of preparation hybrid inorganic-organic; JP 06287470-1994 " Abrasion-resistant acrylic polyurethane coating composition " with silicon sol, contain isocynate silane coupling agent and the many palaces of hydroxyl and can roll into a ball acrylate and prepared urethane acrylate hydridization wear-resistant paint etc.
For the main means of coating static resistance are to add electroconductibility composition, the electric charge of ejecting/collecting effectively.As: CN1147552C is the method that adopts the mica conducting powder, has prepared polyurethane antistatic coating; CN1085927 is with aluminium powder system polyurethane antistatic coating; CN101260277A is with conducting powder system acrylic acid polyurethane antistatic paint; CN1184267C has made vinylformic acid, Resins, epoxy, polyester and polyurethane electrostatic resistance varnish with conductive carbon black; Lin Liping (material and surface treatment .2001, (7): 47-48) then adopt organic antistatic agentses such as S-1, ASA-150, ASB-2, ASB-5 to research and develop zapon varnish.
Giving the coating antibiosis function mainly is by adding the method for antiseptic-germicide.As: use triclosan and pyrithione antiseptic-germicide among the CN101250344A, prepared water anti-bacteria coating; Propose among the CN1436820A with commercially available be that antimicrobial component adds in the commercially available building coating and prepares antibiotic paint with silver, copper, zinc metal ion phosphate-based, that silicate is, oxide based inorganic materials is carrier; The CN100355839C invention is the antibiotic paint with titanium dioxide and the preparation of T-ZnO whisker silicon oxide antiseptic-germicide; People such as Shao Qing had once at large summarized antibiotic paint research new development (material Leader .2008,22 (3): 60-62,71), had described natural antibacterial agent, organic class antiseptic-germicide and mineral-type antiseptic-germicide.The mineral-type antiseptic-germicide comprises: mercury, silver, copper, zinc and compound thereof and inorganic carrier bonded preparation.
These effort are being more effective aspect the coating functional requirement that solves separately, antibacterial or static resistance or wear resistance aspect as coating, but what adopt respectively is special-purpose functional additive or the unifunctional method of modification, does not have comprehensive ground to solve wear-resisting, the anti-electrostatic and the germ resistance problem of coating simultaneously.Say on the other hand,, also exist complex process or cost keeping or " sacrifice "/some coating fundamental propertys of reduction or improve functional inapparent problem even solved single functional issues.
The bright grade of Chu Long is at " research of ZnOT-ZnO whisker complex antimicrobials " (material Leader .2003,17 (6): 84-85,79) in, speak of the preparation that is used for resin concentrates with four needle-like ZnO whiskers and sodium rice zinc oxide and sodium rice zinc oxide titanium complex antimicrobials, as plastics such as low density polyethylene (LDPE)s.The inventor had also once invented " high abrasion, antistatic type polyurethane material " (ZL2005100458985) patent.But all do not relate to four pin shape ZnO whiskers play wear-resisting, anti-electrostatic and germ resistance comprehensive function in coating effect.
