Description
Technical field
The present invention relates to Material Field, and in particular to polymer.
Background technology
Fluorine material has excellent physico-chemical property and mechanical performance, is widely used in each neck of the national economic development
Domain, has especially turned into irreplaceable raw material in space flight and aviation, defence and military and high-technology field.In national oil chemical industry
Be fluorinated in " 12 " development plan work be one it is special a piece is single-row is planned, and listed in by State Economic and Trade Commission, the Department of Science and Technology ought
One of preceding state key encouragement, the high-technology field given priority to, " 12 " emphasis hair is also listed in by work office of national defence section
The high end materials of exhibition.Fluorocarbon resin coating material receives much concern because of its excellent physical and chemical performance, and China is after the U.S., day
The 3rd possesses fluorocarbon coating synthetic technology and realizes the country of industrialization after this.Current China has turned into fluorine the biggest in the world
Chemical industry primary producing country and exported country, but apply research and development deficiency, technical merit to fall behind and allow domestic fluorine chemical industry to be difficult to
Break away from the passive situation that low-end product is superfluous, high-end product is not enough.High-technology field, such as photovoltaic industry, communication electronics are produced
Industry, the appearance and development of New Energy Industry, the coating material of its critical component to traditional fluorocarbon resin retain high-weatherability and
Chemicals, in the performance basis such as water and oil-resistant, easy to clean, it is proposed that new requirement：Such as high-flexibility, rub resistance high
Property, self-cleaning property and is produced on a large scale.
At the same time, (referring mainly to skin surface) and ocean (referring mainly to oceanographic equipment outer surface) two kinds of rows are built
The coating used in industry is although numerous, but antifouling automatic cleaning coating species is simultaneously few.Current nonpolluting coating is limited primarily to propylene
Acid esters coating, the coating of silicon third and the class of Fluorocarbon resin coating three.Because the coating performance of single base-material compounding is difficult in adapt to again
Miscellaneous external environment, also appears in the newspapers repeatly to above-mentioned three kinds of coating modified products.It is to use modified propylene than more typical two class
Acid esters coating, organic silicon-acrylate composite coating.Wherein acrylate type coating is preferable in terms of weather resistance, antifouling effect
It is really undesirable.Organic silicon-acrylate composite coating is mainly ageing-resistant, the UV resistant irradiation, resistance in acrylate coatings
In corrosion and the performance basis such as water-fast, alkaline-resisting, coating performance is improved using organosilicon, make coating have preferably it is heat-resisting, antifouling,
Characteristic, thus the relative acrylate coatings, the Technological Economy good combination property of the type coating, anti-fouling effect such as do not after-tack under high temperature
Also have some improvement.More than improve coating compared with, without improved Fluorocarbon resin coating have longer durability, more preferably
Antifouling property, but production cost it is high, using being limited to.Even if in addition, outstanding Fluorocarbon resin coating still cannot be realized
It is antifouling from source, also, the weatherability of these materials, drug-resistant aspect of performance still need to improve to adapt to external working environment
It is required that.In a word, comprehensive various aspects of performance, especially at antifouling aspect, fluor resin coating show at present it is most with prospects, and
Because its low-surface-energy also has good potential in terms of friction resistant.For actual demand, domestic or even two kinds of the whole world
All there is antifouling automatically cleaning in industry " object " (such as in-service ship).Market existing procucts unitary function, although temporarily
Certain aspect functional requirement can be met, but generally existing life of product is short, consumption big, or even there is secondary pollution defect.
Currently there are some researchs in fluorosilicic block copolymer forward position, such as positive letter of sieve etc. is adopted in CN101215364A
Dimethyl silicone polymer-b-polymethyl methacrylate-b-poly- seven fluorine butyl methyl third is prepared for atom transfer polymerization
Olefin(e) acid ester.This kind of product remains the characteristic of fluorine silicon, and reduces cost by PMMA, but due to the rigidity of segment itself, nothing
Method is used in the larger occasion of basic unit's STRESS VARIATION, is easily caused cracking phenomena；In CN103435764A big vast outstanding person et al. in sieve just
The concentration of catalyst is improved on the basis of letter, but target product is basically identical；Cheng Xitao et al. is used in CN104193923A
The method of micro- heating equally uses ATRP, prepares the triblock polymer of hydrophobic/oleophobic fluorine silicon.
CN101983976A Li Hui et al. prepare the block copolymerization of dimethyl siloxane-polyacrylic acid fluoroalkyl fat using RAFT techniques
Thing；Li Hui et al. is prepared for fluorosilicone-POSS acrylate block copolymers for biomedical neck in CN103524752A
Domain；Liu Yue great waves et al. are prepared for the copolymer of organic fluorinated silicone-polyurethane blocks and are generated in field of textiles in CN105646828A
Effect.
These researchs focus mostly on and are using silicone backbone, and fluorine-containing functional group pendant has reached the fundamental characteristics of fluorine silicon,
Some researchs take into account cost, and some researchs take into account pliability.But research is there is no for building and marine anti-pollution two
The market development targetedly product.This patent is to have considered construction market for cost and the demand of adhesive force.
