Summary of the invention
Object of the present invention provides a kind of formula of heat-resistance type nanometer easy-cleaning paint.
The present invention, by the development of coating, is that nano paint has better property easy to clean, gives the better temperature tolerance of this coating, preferably hardness simultaneously, this type coating is more widely used.
For achieving the above object, the present invention by the following technical solutions:
A kind of heat-resistance type nanometer easy-cleaning paint, according to parts by weight, consists of the following composition: the special fluorine silicon resin of 50 ~ 70 parts, the cure-crosslinking agent of 5 ~ 15 parts, the special fluorine silicon additive of 1 ~ 3 part, the flow agent of 1 ~ 3 part, the thinner of 10 ~ 30 parts.
Further, described special fluorine silicon resin is fluorine-silicon copolymer resin.
Further, described cure-crosslinking agent is tripolymer class cure-crosslinking agent.
Further, described flow agent is silicone based or polyacrylic.
Further, described thinner is alkoxide solvent.
Dispensing information:
Special fluorine silicon resin refers to fluorine-silicon copolymer resin, is by fluoro-resin and the mixing synthetic resins of silicone resin.There is excellent temperature tolerance, resistance to bond, chemical-resistant, didirtresistance and ornamental.The present invention select performance comparatively superior, the fluorine silicon resin with heatproof (being greater than 220 degree), hardness (being greater than 3H) and better easy clean property, particular type can under 300 degree life-time service.
Cure-crosslinking agent is the material of a kind of promotion or telomerized polymer molecule interchain covalent bonds or ionic linkage formation.Linking agent is small molecule compound, molecular weight is generally between 200 ~ 600, there is 2 or the more reactive terminal for specific groups (amino, sulfydryl etc.), can with 2 or more molecule coupling thus these molecular juction are combined respectively, make the mutual bonding cross-linking of multiple thread-like molecule become the material of network structure at line style intermolecular bridging action.The material of promotion or telomerized polymer molecule interchain covalent bonds or ionic linkage formation, it can make the macromole of line style or slight branched chain type be transformed into tridimensional network, improve the performances such as intensity, thermotolerance, wear resistance, solvent resistance with this, be usually again " solidifying agent ", " stiffening agent " etc.It is of a great variety, and different according to selected main body, the cure-crosslinking agent used is also different.Due to the use of cure-crosslinking agent, product of the present invention can be solidified under normal temperature state and baking condition, operate and use more flexible.The present invention has selected the tripolymer class cure-crosslinking agent matched with matrix resin.
Flow agent, it can impel coating in drying and forming-film process, form smooth, smooth, a uniform film.Effectively can reduce and cover with paint, lacquer, colour wash, etc. liquid surface tension, improve a class material of its levelling property and homogeneity, the present invention has selected silicone based or polyacrylic.
Thinner, being mainly used in viscosity when regulating spraying to use, is that spraying application is easily more convenient.Less alcohol ester (as methyl alcohol, the N-BUTYL ACETATE etc.) kind solvent of choice for use environmental pollution of the present invention as the diluting solvent of product of the present invention, and within the discharge scope being strict controlled in VOC (being less than 420g/L).
The present invention has following beneficial effect:
This invention by formula modulation, make such easy-cleaning paint have temperature tolerance (be greater than 220 degree, indivedual system can heatproof to 300 spend) while, there is stronger easy clean property, due to the use of cure-crosslinking agent, make curing mode also more flexible.This invention containing heavy metal, does not meet WEEE, the environmental requirements such as RoHs, FDA, is applicable to every profession and trade.
