Abstract

The present invention relates to a non-sticking paint containing fluorine-silicon material, which is composed of a paint part and a solidifying agent part. The dosage of the solidifying agent is from 6.5% to 12% of the weight of the paint part. The paint part mainly comprises fluorocarbon resin, 10% to 20% organic silicon resin, 3% to 30% of color filling material, 1% to 5% of silicon miropowder, 3% to 10% of fluorine miropowder, etc. The solidifying agent is at least one of biuret, HDI trimer and organic tin. The fluorocarbon resin is formed by the copolymerization of tetrafluoroethylene monomers, alkyl vinyl ester and functional monomers, wherein the fluorine content is not lower than wt 35%, and the solidifying content is not lower than 50%. The organic silicon resin is end-hydroxyl organic silicon resin. The non-sticking paint of the present invention has the advantages of good non-sticking performance, normal temperature drying, aging resistance and easy construction.

Description

A kind of silicon fluoride super-amphiphobic non-stick coating material
(1) technical field under
The present invention relates to a kind of non-adhesive coating, particularly a kind of non-viscous paint of fluorine silicon material.
(2) background technology
The existing non-viscous paint in market can roughly be divided into two classes: a class is cooker and household electrical appliances non-viscous paint, and another kind of is anti-graffiti class non-viscous paint.Last class is representative with Du Pont's " teflon ", owing to be subjected to the influence of carcinogenic substance Perfluorocaprylic Acid amine, its safety performance is just being endured common people's suspection to the fullest extent, and the second class coating owing to be subjected to the influence of various factors, also has the following disadvantages:
1, viscosity not there is no special salient point;
2, the product that has can not Air drying, and its construction is affected by environment big;
3, range of product is single, and decorative effect is relatively poor;
4, product for a long time not viscosity can't guarantee.
(3) summary of the invention
The present invention is in order to overcome the deficiency of above technology, provide a kind of not viscosity can be good, Air drying, ageing-resistant, the silicon fluoride super-amphiphobic non-stick coating material that is easy to construct.
The present invention realizes by following measure:
Silicon fluoride super-amphiphobic non-stick coating material of the present invention is made up of base-material part and solidifying agent two portions, and hardener dose accounts for the 6.5-12% of coating part weight,
Described base-material partly is made up of following raw materials by weight percent:
Fluorocarbon resin 30~50%
Silicone resin 10~20%
Color stuffing 3~30%
Silicon powder 1~5%
Fluorine micro mist 3~10%
Auxiliary agent 0.01~3%
Organic solvent 5~30%;
Described solidifying agent is at least a of biuret, HDI tripolymer and organotin;
Described fluorocarbon resin is to be formed its fluorine content 〉=wt35%, solid content 〉=50% by tetrafluoroethylene monomer, alkyl vinyl ester and function monomer copolymerization; Described function monomer is one or both of vinyl carbinol and undecylenic acid;
Described silicone resin is the terminal hydroxy group silicone resin;
Described fluorine micro mist is a ptfe micropowder, particle diameter≤5um; Described silicon powder is an aerosil, particle diameter≤5um.
Non-viscous paint of the present invention, described alkyl vinyl ester is a vinyl acetate.
Silicon fluoride super-amphiphobic non-stick coating material of the present invention, described organic solvent are ester class, ketone or solvent of ether ester type.
Non-viscous paint of the present invention, with tetrafluoro resin and terminal hydroxy group silicone resin is matrix resin, the main low surface energy characteristic of using the fluorine silicon materials, thereby macro manifestations is for scolding water, scold the two thin performance of oil, cooperate particle diameter less than 5 microns fluorine micro mist, silicon powder, in order to strengthen the two thin performances and the lubricity of filming, certain pigment filler realizes multiple ornamental, functional agent and ketone, the needs in production and the construction process have been satisfied in the application of organic solvents such as ester class, cooperate biuret, the HDI tripolymer, solidifying agent such as organotin, in concrete construction application, both can in warm forced drying, also normal temperature solidified, enlarged the range of application of product.
Silicon fluoride super-amphiphobic non-stick coating material of the present invention can adopt the preparation method under recognizing: add part organic solvent, fluorocarbon resin, silicone resin, auxiliary agent in the jar of a constant volume, using dispersion machine simultaneously is uniformly dispersed with certain speed, according to different requirements, add color stuffing, requirement difference according to color stuffing, determine whether sand milling, really need sand milling, control sand mill discharging fineness.Then, remaining fluorocarbon resin, silicone resin, auxiliary agent and organic solvent add paint mixing tank in will filling a prescription, and obtain the coating part of described silicon fluoride super-amphiphobic non-stick coating material after stirring.In above-mentioned preparation technology's method, equipment is the normal temperature and pressure state.
The coating part of getting above-mentioned preparation mixes with an amount of solidifying agent, adds a certain amount of thinner and adjusts viscosity, can construct.
Silicon fluoride super-amphiphobic non-stick coating material of the present invention has following performance:
1, range of product is abundant, and real chromatic effect, metallic travel, pearl effect and transparent effect are arranged;
2, ultra-amphosphobic, after the dried coating film, not sticking to any water-based and oily matter, the small advertisement that shows as stickups such as glue, paste all can come off in 10-30 minute automatically, and the small advertisement that uses non-setting adhesive to paste is easy to peel off, and does not stay any stain;
But 3, product Air drying, also can in warm forced drying, construction can be adopted spraying, roller coat and brush multiple mode;
4, anti-outdoor aging, outdoor use can not produce efflorescence, variable color more than 20 years;
5, be applicable to multiple base materials such as cement, metal matrix, plastics, timber, pottery.
