Description
Technical field
The present invention relates to technical field of coatings more particularly to a kind of high glossy low friction type anti-fouling paints.
Background technique
Branch's attachment in the middle part of seawater is soaked in below drauht line, and there are many resistances that marine organisms, marine organisms generate
Not only increase marine fuel consumption, but also is the main reason for ship sea speed reduces.What use was most wide at present is to contain
Tin compound antifouling paint, this coating price is cheap, raw material easily obtains, anti-pollution is brilliant, and ship is made to have a small amount of ocean
Biological attachment.But existing sn-containing compound antifouling paint can release environmental hormone, be that current putative marine pollution is main
One of factor.The most newly developed principle gradually worn out using antifouling paint in ship navigation come play anti-pollution self
The antifouling paint of wear pattern can avoid release environmental hormone, and prevent marine organisms when ship navigation from adhering to greatest extent；But
The coating strength of this coating is very fragile, needs frequent progress Painting in Maintenance, and and do not solve big when ship berths for a long time
Measure marine organisms attachment issue.
Such as Korean Patent Publication No. 99-61474 (on July 26th, 1999 is open), Korean Patent Registration the 254651st
In self above-mentioned wear pattern antifouling paint recorded in (registering on 2 3rd, 2000) etc., because antifouling paint and seawater occur instead
It answers, and enters anti-fouling composition in seawater, therefore there are problems that frequent Painting in Maintenance, and in the case where berthing for a long time,
There are a large amount of marine organisms attachments because anti-fouling composition can not actively gush out.
In addition to this, the interior sidewall surface of the piping of farm or extracting seawater made of concrete, water-supply line, sewer
Etc for transfer medial surface of various pipings of fluid etc. also can there is a phenomenon where foreign matters adhere to, do not only result in fluid flow
It has some setbacks, and foreign matter has caused piping to be corroded, so that service life reduces, increased costs.
Summary of the invention
To solve the above problems, there is outstanding prolong the invention proposes a kind of high glossy low friction type anti-fouling paint
Rate, spring rate, abrasion performance, soil resistance, durability, cohesive force are stretched, can avoid vessel motion or sea occurs when berthing for a long time
The phenomenon that foreign biological attachment and Ship's corrosion, it is not easy to cause environmental pollution.
In order to solve the above-mentioned technical problem, present invention employs following technical proposals: a kind of high glossy low friction type is anti-
Dirty coating, including pre-polymer solution and resin solution, the pre-polymer solution and resin solution after the ratio mixing of 1:1 to carry out
It uses；For the pre-polymer solution by the methylene diisocyanate of 100wt%, the methylene diisocyanate contains 8wt%
The NCO of~12wt%；The resin solution includes point of the polypropyleneoxide diamine of 42wt%~48wt%, 8wt%~10wt%
Son amount for 5000 polyethers triamine, the poly- diphenylamine of 15wt%~20wt%, 8wt%~20wt% modified amido silicone resin,
The modified fluorin resin of 0.5wt%~10wt%, the modified resin filler of 4wt%~7wt%, 1wt%~2wt% binder
And the pigment of 1wt%~2wt%.
The pre-polymer solution is the methylene diisocyanate of 100wt%, determines the antifouling painting of high glossy low friction type
The component of the physical property such as integral hardness, weatherability and the elongation of material；Wherein, NCO content is higher, the hardness of film mistake after solidification
Height, NCO content is lower, and the hardness of film after solidification is lower, it is preferred, therefore, that methylene diisocyanate NCO of the present invention
Content is 8wt%~12wt%.
Polypropyleneoxide diamine in the resin solution is used to adjust the elongation percentage and tensile strength of film, the polyoxy third
When alkene diamines additive amount is less than 42wt%, film elongation percentage is lower, when the polypropyleneoxide diamine additive amount is greater than 48wt%, applies
Film elongation percentage and tensile strength increase, but abrasion performance reduces, it is preferred, therefore, that polypropyleneoxide diamine of the present invention with
The range of 42wt%~48wt% is added.
For adjusting curing time, the molecular weight is the polyethers triamine that molecular weight in the resin solution is 5000
When 5000 polyethers triamine additive amount is less than 8wt%, curing time is elongated, the polyethers triamine additive amount that the molecular weight is 5000
When greater than 10wt%, there is the phenomenon that appearance is reduced with adhesive force reduction because curing time is too fast, it is preferred, therefore, that this hair
The polyethers triamine that the bright molecular weight is 5000 is added with the range of 8wt%~10wt%.
Poly- diphenylamine in the resin solution is for adjusting solidification physical property and improving elongation percentage, the poly- diphenylamine
Additive amount is less than 15wt%, and when for adjusting curing time, increasing elongation percentage, film coated surface remains dope, after solidification still
There are residues, and surface is caused to be contaminated, upper foreign matter easy to stick, and abrasion performance reduces, and the poly- diphenylamine additive amount is greater than
20wt%, when for adjusting curing time, increasing elongation percentage, although curing time accelerates, durability is reduced after realizing solidification,
Easily there is the phenomenon for fractureing or being crushed, it is preferred, therefore, that poly- diphenylamine of the present invention is with the range of 15wt%~20wt%
Addition.
Modified amido silicone resin and modified fluorin resin in the resin solution is for improving sliding property and soil resistance；It is described
When modified amido silicone resin additive amount is less than 8wt%, sliding property and soil resistance are reduced, and can not prevent foreign matter attachment phenomenon, described
When modified amido silicone resin additive amount is greater than 20wt%, sliding property and soil resistance enhancing, interlayer adhesion are reduced, and elongation subtracts
It is small, it is preferred, therefore, that modified amido silicone resin of the present invention is added with the range of 8wt%~20wt%；The modified fluorine tree
When rouge additive amount is less than 5wt%, sliding property and soil resistance are reduced, and can not prevent foreign matter attachment phenomenon, the modified fluorin resin adds
Dosage be greater than 10wt% when, interlayer adhesion reduce, elongation reduce, it is preferred, therefore, that modified fluorin resin of the present invention with
The range of 5wt%~10wt% is added.
Modified resin filler in the resin solution is for improving abrasion performance, preferably, the Modification
Agent is nano silicate, is added with the range of 5wt%~9wt%.
Binder in the resin solution keeps the mixing between each component more smoothly and improves between substrate substrate
Bonding force, it is preferred that the binder be selected from β-(3,4- epoxycyclohexyl) ethyl trimethoxy silane, γ-propyl front three
One of oxysilane, γ-methacryloxypropyl trimethoxy silane, the content of binder are less than 1wt%
When, cohesive force reduces, and when the content of binder is greater than 2wt%, cohesive force increases but abrasion performance reduces, it is therefore preferable that
, the binder is added with the range of 1wt%~2wt%.
Pigment in the resin solution goes out tone for rendering；When the pigment additive amount is less than 1wt%, color is shielded
It covers, can not present, when the pigment additive amount is greater than 2wt%, can not be presented because color is concealed, it is preferred, therefore, that this hair
The bright pigment is added with the range of 1wt%~2wt%.
High glossy low friction type anti-fouling paint of the present invention is as follows the step of forming stain-proofing layer on substrate:
S1, substrate pre-treatment step to Ship body water line section below or are used for fluid and gas using power tool
The substrates such as the inside face of body transfer tube, the steel pipe of water channel, concrete water tank are pre-processed, and foreign matter is removed, and primer coating increases
Adhesive force between substrate and high glossy low friction type anti-fouling paint of the present invention；
