2. refuses the ceaseless promotion of colophony of bacterium gel coat as breed of gel coat resinous and function, gel coat resinous applies a domain to expand ceaselessly, provide in wholesome clean at present, the respect such as housing of instrument of industry of shipbuilding industry, traffic carrying trade, bldg. , entertainment, medical treatment, billboard, booth and security personnel booth got applied. The sex that fight bacterium is resinous of the gel coat that fight bacterium index of a main function, it is affecting resinous of the gel coat that fight bacterium directly further progress and application, the factor that because this research affects his,defies bacterium function has very important sense. The Gao Chengchao of science of Zhejiang university material and place of engineering courtyard inorganic it is carrier with silicon collosol, the 2 oxidation silicon that belongs to precipitation of silver-colored ionic TiO2, ZnO2 and dissolve of Al2(SOi3)3 Yu Gui through laden Namijin apparently, preparation compound inorganic fights bacterium agent, the preparation in joining its gel coat colophony colophony of the gel coat that fight bacterium. The preparation parameter that studied the agent that fight bacterium, content and sort and parameter of preparation of resinous of the gel coat that fight bacterium resist the influence of bacterium function to gel coat colophony. Experimental result makes clear as firing temperature elevatory, resinous of the gel coat that fight bacterium fights bacterium to lead the current that after appearing to lift first, reduces, firing temperature is the agent that fight bacterium when 1000 ℃ , resinous of the gel coat that fight bacterium fights bacterium rate is high; Grind the extension of time as the ball, resinous of the gel coat that fight bacterium fights bacterium rate to show ascendant trend, the ball grinds time to be more than 6h to fight bacterium to lead addition scope to reduce; As the addition of styrene content, its fight bacterium rate to also increase gradually, styrene content is 10% when the rate that fight bacterium is amounted to 94% ; Along with the extension of agitate time, resinous of the gel coat that fight bacterium fights bacterium rate to also increase somewhat, agitate time fights bacterium to lead for 1h for 94% . 3. Solidify of ultraviolet light of colophony of gel coat of ultraviolet light solidify has the advantage such as low pollution, feebleminded bad news, fast solidify, tall productivity. Gao Qingyu of chemical college of Henan university chemistry and Li Xiaogong use a benzene respectively benzene of 2 formic acid, adjacent 2 formic acid and its both mixture (, the quantity of material of anhydride of 2 formic acid compares adjacent benzene for 4: 1) and binary alcohol (third 2 alcohol and shrink the quantity of 2 glycol material compares for 4: 1) reaction synthesized colophony of 3 kinds of gel coat (it is respectively - UPR, adjacent - UPR and mix - UPR) . After quality mark should be being joined to make smooth initator for the benzoic ether of 1% in colophony, 30min of ultraviolet light illuminate can solidify. After solidify, the acid-proof and alkalescent, solvent resistance of child and exterior burnish are good with adjacent benzene colophony. Studied with the method such as infra-red spectrum its are ultraviolet solidify process, studied the hot property of condensate with TG-DTA law, the.UPR between discovery does not have weightlessness almost below in 300 ℃ , and adjacent - UPR begins weightlessness namely in 100 ℃ left and right sides. In addition, thermal stability of smooth solidify resinous is good the colophony that crosses oxide solidify at using. 4. Anti-fouling the Kaarnakari of Ashland Inc of United States of coating of gel of not saturated polyester, the hair palpability such as Matti is provided be able to bear or endure corrupt coating of gel of not saturated polyester, reported will contain be able to bear or endure corrupt the application that the coating of gel of not saturated polyester of the agent makes marine coating. Gel of not saturated polyester is able to bear or endure corrupt coating is contained be able to bear or endure corrupt agent, should be able to bear or endure corrupt the agent is chosen from 4, 5- 2 chloric - 2- Xin Ji - ketone of Lin of 4- different thiazole - 3, annulus propyl - N’-(1, 1- 2 methylic second base) - 6-(methylic sulfur is acting) - 1, 3, 3 Qin of 5- - 2, 2 amine of 4- and N’[(fluorine - 2 chloric - methylic) sulfur is acting] adjacent benzene 2 acyl inferior amine or its mixture. This invention still involves gel of not saturated polyester to be able to bear or endure corrupt the preparation of sexual coating.
