Description
Technical field
The present invention relates to a kind of sanitary ware, specifically a kind of antibacteria type water tap.
Background technology:
Along with the enhancing of health of people consciousness, the quality problems of tap water cause the public's concern day by day.A large amount of financial resources are all dropped in various places, material resources clean, sterilize to guarantee the up to standard of resident living water water source and water supply network, be used for public supply mains as developing water pipe, in the fluming water process, be not secondary polluted guaranteeing with antibacterial.Yet as the sink node of water channel, the water tap that uses at user side does not but have any anti-microbial property.Because water tap inside easy cleaning not is in obturation, the wet environment for a long time, breed bacteria very easily, thereby make current through out-of-date contaminated, and then give the people healthyly bring harm.Therefore the germ resistance of water tap becomes the subject matter that whether can guarantee water safety at present finally, effectively.
CN1607215 discloses a kind of plastics kitchen utensils with antibacterial, the antimicrobial powder that wherein contains 1-1.5% (weight), the primary particle size of this powder is 75-115nm, and it is that to be embedded in wherein particle diameter by the zirconium phosphate carrier of tool laminate structure and absorption be that the metallic silver particles of 10-20nm constitutes.The antibacterial of these plastics kitchen tools is that 24 hours antibiotic rates are about 90%.Still there is certain gap in obvious its antibacterial aspect.
Summary of the invention
Purpose of the present invention is exactly that a kind of antibacteria type water tap with high antibacterial will be provided, to reduce the secondary pollution of running water system to water to greatest extent.
The object of the present invention is achieved like this: antibacteria type water tap is to be made by antibiotic plastic, described antibiotic plastic is to add the antibacterial matrices that accounts for multipolymer weight 1-1.5% in propylene fat-butadiene-styrene copolymer, described antibacterial matrices is to make by add the antimicrobial powder account for multipolymer weight 20-30% in propylene fat-butadiene-styrene copolymer, and described antimicrobial powder is to carry silver-colored body and auxiliary agent is mixed and made into by zirconium phosphate; The particle diameter that zirconium phosphate carries silver-colored body is 75-115nm, wherein contain account for zirconium phosphate weight 3-8%, particle diameter is the metallic silver particles of 10-20nm; Auxiliary agent is made up of the amphiphilic dispersion agent of the 1-2% that accounts for antimicrobial powder weight, the polyethylene wax that accounts for the coupling agent of antimicrobial powder weight 2-3% and account for antimicrobial powder weight 1-2%.
Wherein the amphiphilic dispersion agent is selected the SOLSPERSE series product of ICI company or the CH series product of ShangHai SanZheng polymer Materials Co., Ltd for use, and coupling agent is selected titanate ester or silane coupling agent for use.
Propylene fat-butadiene-styrene thermoplastic multipolymer is commonly referred to ABS, because its heat-resisting processibility and shock resistance are better, can satisfy the technology and the characteristic requirement of processing and fabricating water tap, so the present invention selects the material of main part of this material as preparation antibacteria type water tap parts.
Among the present invention, antimicrobial powder is a carrier with the zirconium phosphate with laminate structure, and nano-Ag particles is embedded in the laminate structure of zirconium phosphate.And can be by known preparation method's preparation.
The amphiphilic dispersion agent has anchoring base and solvent chain (the polymkeric substance long-chain with certain molecular weight), and coupling agent has while and mineral filler and the affine performance of macromolecule matrix, and polyethylene wax is a WE type macromolecule wax.The applicant is in test repeatedly, be surprised to find that and use above-mentioned three kinds of raw materials to make up as auxiliary agent, add in the antimicrobial powder, anti-microbial property that prepared antibiotic plastic had and time length obviously are better than using separately the antibiotic plastic of coupling agent as dispersion agent.
Amphiphilic dispersion agent among the present invention preferably uses the CH-1A of SOLSPERSE17000 or ShangHai SanZheng polymer Materials Co., Ltd.Coupling agent is selected titante coupling agent for use, and the product of the NDZ specification of producing with Nanjing dawn chemical industry one factory is good as coupling agent NDZ-1 or coupling agent NDZ-2.Coupling agent is selected silane coupling agent for use, the KH series product that adopt Nanjing dawn chemical industry one factory to produce.The molecular weight of polyethylene wax is 2000-10000, can preferably adopt the product of the WE specification of Kingsoft, Shanghai Venus plastic molding and processing plant production, as polyethylene wax WE-3 or polyethylene wax WE-2 etc.
Key of the present invention is to have selected the proper auxiliary agent combination and cooperates consumption, make the dissolution rate of antibiotic composition of the antibacterial water tap of being produced moderate, antibacterial longer duration not only, can reach more than 10 years, and antibacterial ability is strong, can reach more than 99.9%, so be particularly suitable for the antibiotic needs of water tap.
