Abstract

The present invention relates to a kind of ceramic sanitary appliance self-cleaning composition, it is made up of tri- kinds of components of A, B, C, wherein A has been the fluorocarbon resin and related auxiliaries of filming function, B is the polysilazane with hardening crosslinked action, organo-silicon coupling agent and its diluent, and C is the isocyanate curing agent for solidifying fluorocarbon resin.After composition is fully cured on ceramic sanitary appliance surface, the contact angle of the composition film and water is more than 150 °, it is more than 120 ° with the contact angle of soybean oil, therefore it is easy to be taken away by water droplet when spot stays in film coated surface, reach automatically cleaning effect, the film has wide spectrum, efficient sterilizing effect simultaneously, and Durability of antimicrobial effect was up to more than 5 years.

Description

A kind of ceramic sanitary appliance self-cleaning composition
Technical field
The present invention relates to a kind of ceramic sanitary appliance self-cleaning composition, belong to the technical field of surface of ceramic sanitary appliance.
Technical background
In nature, lotus leaf surface has unique self-cleaning function, larger contact angle can be formed with water surface, is referred to as Lotus leaf effect or super-hydrophobic effect.Because the contact area of super hydrophobic surface and water droplet is very small, and water droplet easily rolls from table Fall, therefore, super hydrophobic surface not only has a self-cleaning function, but also with it is anti-electric spread lead, it is anticorrosion, waterproof, antifog, anti- Mould, snow defence, frost protection, it is anti-the function such as stick, be anti-pollution, thus in building, textile clothing, liquid conveys, is biomedical, daily The fields such as product and packaging, transport facility and micro-analysis are all with a wide range of applications.
Chinese patent 201310043491.3 discloses a kind of super-hydrophilic self-cleaning coating formula and its film-forming products, and the formula includes pressing The following component calculated according to percentage by weight:Water nano resin 10%~20%;Nano-scale alumina slurry 30%~50%; BYK023 is 0.1%~0.5%;Ethanol 10%~50%;Deionized water is as surplus;The invention nano-resin is as film forming agent Use;Hydrophilic coating is used as using nano-scale alumina slurry;Defoamer and levelling agent are used as using BYK023;Cosolvent is used as using ethanol. In in use, by the super-hydrophilic self-cleaning coating matched spraying, showering or brush on the surface of product, dry at normal temperatures Film forming or the film forming after 60~70 DEG C of bakings, the coating surface formed can be spontaneously wet out by water completely, and contact angle is less than 5 degree. Due to too small with water contact angle, the self-cleaning coating described in the invention is not suitable in the pottery that spot easily stops, bacterium easily grows Porcelain field of sanitary.
The content of the invention
The shortcomings that to overcome prior art and deficiency, primary and foremost purpose of the invention are to provide a kind of ceramic sanitary appliance automatically cleaning Composition.
A kind of ceramic sanitary appliance self-cleaning composition of the present invention is made up of tri- kinds of components of A, B, C, and concrete composition is as follows Table:
Described fluorocarbon resin 20~80mg of hydroxyl value KOH/g.
Described levelling agent is organosilicon levelling agent, preferably TEGO450, TEGO4100, BYK450, BYK415, BYK333, At least one of BYK358, BYK306.
Described bactericide is that solvent-borne type is complexed silver ion disinfectant, concentration 2000ppm.
Described diluent is in petroleum ether solvent, ethyl acetate, butyl acetate, kerosene, diesel oil, ethanol, n-butyl ether, butanol It is at least one.
Described organo-silicon coupling agent is that tetraethyl orthosilicate, methyl silicate, gamma-aminopropyl-triethoxy-silane, γ-shrink are sweet Oily ether oxygen propyl trimethoxy silicane, γ-methacryloxypropyl trimethoxy silane, trimethoxymethylsila,e, three At least one of (ethoxymethyl) base silane.
The polysilazane be Perhydropolysilazane, organopolysilazane, boron hydridization organopolysilazane, boron hydridization perhydro gather At least one of silazane.
The isocyanate curing agent is low-free TDI tripolymer, low free MDI tripolymer, low free HDI trimer, low trip From at least one of IPDI tripolymers.
The described anti-skidding Wax composition of water-based ceramic tile imposes on ceramics after using preceding be sufficiently mixed A, B, C uniformly, by spraying Sanitary equipment surface, after surface drying, it is fully cured after 60~80 DEG C of freeze-day with constant temperature 12h.
Relative to prior art, ceramic sanitary appliance self-cleaning composition of the present invention has advantages below or benefit:(1) use Fluorocarbon resin does film forming basic resin, the composition have than excellent acidproof, alkaline-resisting, weatherability, water and oil repellence, it is anti-stick, Resistant to pollution excellent properties;(2) most hard synthetic resin polysilazane resin makees hardening agent, the composition film known to selecting Afterwards, polysilazane resin self-crosslinking in the presence of Karsted catalyst, simultaneously participate in and fluorocarbon resin crosslinking and isocyanic acid The cross-linking reaction of ester curing agent, composition film densification is hard, adhesive force is good;(3) after being fully cured on ceramic sanitary appliance surface, institute The contact angle for stating composition film and water is more than 150 °, is more than 120 ° with the contact angle of soybean oil, therefore when spot stays in film It is easy to be taken away by water droplet during surface, reaches automatically cleaning effect;(4) in the composition containing wide spectrum, efficiently, safety silver from Sub- bactericide, antibacterial effect was up to more than 5 years.
