Abstract
A room hanging board method for evaluating antifouling property of resin which is coating resin on blank board with width of 2.5-5cm, length of 7.5-15cm and height of 2.5-5cm in room; solidifying said coat on board then putting prepared board in artificial cultured algae liquid in index growth period, taking said board out at each interval 6-12hr.for observing algae number attached on different resin, evaluating antifouling proper of resin according to variation of algae cell concentration in algae liquid.
Description
Technical field
The present invention relates to a kind of indoor link plate evaluation method of resin antifouling property.
Background technology
At present, antifouling paint mainly is made up of resin, anti fouling agent, auxiliary material, inserts and 5 kinds of components of solvent, and wherein resin and anti fouling agent are the key components of antifouling paint.In essence, the development of antifouling paint depends on the exploitation two main lines of the exploitation and the novel antifouling agent of new type resin.And the resin with superperformance is one of precondition of exploitation high-performance antifouling paint.For resin newly developed, adopt the method for real extra large link plate that its performance is estimated usually, and this traditional evaluation method is subjected to a lot of restrictions at present, not only the cycle is long, be difficult to quantitatively, and affected by environment bigger, and this just is difficult to reach in a short time the purpose of resin screening.Therefore need set up one easy to operate, experimental period short, indoor link plate evaluation method that can be quantitative.
Summary of the invention
The indoor plate-hanging method that the purpose of this invention is to provide a kind of effectively evaluating resin antifouling property is to satisfy the demand of prior art.
A kind of indoor plate-hanging method of effectively evaluating resin antifouling property, it is characterized in that resin to be evaluated being coated the wide 2.5～5cm of being equably indoor, length is 7.5～15cm, height is on the blank plate of 0.25～0.5cm, after doing solid work, this coating model is put into the ARTIFICIAL CULTURE algae liquid of exponential phase, every 6～12 hours this coating model is taken out again, observe algae adhering to quantity or washing model on different resins from microscopically with eluent, algae on the model is as far as possible all swept away, with the negative contrast of blank plate, by the spectrophotometric determination light absorption value or with blood counting chamber counting, according to the antifouling properties of the rate of change evaluating resin of frustule concentration in the algae liquid.
The selected algae of method of the present invention is marine most typical tack algae such as diatom, chrysophyceae or green alga, can be in a short time the antifouling property of resin be simply characterized, to reach the purpose of it being carried out preliminary screening, compare with the extra large plate-hanging method of traditional reality have easy to operate, experimental period short, advantage that can be quantitative.
Embodiment
1, the cultivation of the Nitzschia closterium minutissima algae liquid of experiment usefulness
With seawater scalding after the glass sand core funnel filters, be used to prepare nutrient solution after the cooling, the concentration (concentration expressed in percentage by weight) that this nutrient solution contains nutritive salt is respectively: ammonium nitrate 4%, potassium dihydrogen phosphate 0.4%, urea 1.8%, ferric citrate 0.045%, sodium silicate 2%.Used Nitzschia closterium minutissima algae liquid is cultivated in growth cabinet.The sample bottle that fills Nitzschia closterium minutissima algae liquid vibration all around lightly, frustule is uniformly dispersed.Above-mentioned nutrient solution dilution back with varying number counts to get the concentration of the frustule of each dilution respectively with blood counting chamber, and measures the light absorption value of each dilution frustule in the maximum absorption wave strong point, thereby obtains one group of algae liquid concentration-light absorption value data.And, the algae liquid of cultivating exponential phase is diluted to certain concentration with nutrient solution according to these group data, shake up stand-by.
2, making sheet
To be resin, the N-(6-(acrylamide methyl)-1 that comonomer makes with N-(4-hydroxyl-3-methoxy-benzyl) acrylamide (HMBA), 3-benzo two oxa-s penta ring-5-methyl) resin that makes for monomer of acrylamide (AMBMA) and brush equably on the test plate of 25mm * 75mm * 5mm respectively with the resin that acrylamide monomer makes, spreading area is about 15cm
2, in air, dry naturally, standby.
3, in Nitzschia closterium minutissima algae liquid, carry out the link plate experiment
The model that dries well is put on the model frame, and this model frame is put into the glass jar of the algae liquid that fills above-mentioned ARTIFICIAL CULTURE, and (length * wide * height: 30cm * 25cm * 15cm), under 20 ℃, intensity of illumination is to cultivate under the condition of 8000Lx.Total liquid volume is 5L in the cylinder, throws in two blocks of gas stones, and the initial concentration of algae liquid is 3.88 * 10
5Individual/ml, 13 days link plate time, during detection in the cylinder algae liquid concentration be 1.745 * 10
6Individual/ml.Periodicity of illumination is 12: 12, and nutrient solution still is above-mentioned nutrient solution.
To test model and take out, and at first observe algae from microscopically and adhere to quantity on different resins, the adhesion condition of Nitzschia closterium minutissima on three kinds of different resins is different as can be seen on apparent.Perhaps wash print repeatedly, the algae on the print is as far as possible all swept away,, the algae liquid that sweeps away is counted with blood counting chamber, when algae liquid concentration is too rare, can directly use the spectrophotometric determination light absorption value with the negative contrast of blank plate with the 20ml eluent.Obtain different test findings from the different as can be seen resin of test, the concrete following table that the results are shown in.
The adhesion condition of algae on link plate
As can be seen from the above table, it is many that the resin that does not contain functional monomer contains the frustule that the resin of function monomer HMBA or AMBMA adheres to, and contain the increase of the functional resin of HMBA or AMBMA along with HMBA and AMBMA content, and the frustule quantity that it adheres to reduces.And the frustule that adheres on the glass blank is fewer, and this may be because glass surface can be lower, is not easy to algae and adheres to.
Replace with diatom, chrysophyceae or green alga with the algae Nitzschia closterium minutissima and can obtain similar effects equally if will test; Change blank model into teflon flat board, PE plate, PP plate, ABS plate or PVC flat board and can obtain similar effects equally.
The method of indoor detection resin antifouling property of the present invention is compared the cycle that has reduced the resin screening greatly with the extra large link plate of traditional reality.The selected algae of the present invention is marine most typical tack algae such as diatom, chrysophyceae or green alga, can be in a short time the antifouling property of resin be simply characterized, and reaches the purpose of it being carried out preliminary screening, can obtain good effect.
