Special gel coat resin is developing more and more species, its function is also grown stronger . With the rising variety and performance gel coat resin , gel coat resin application areas expanding , currently in sanitary ware, shipbuilding, transportation, construction , entertainment , medical instrument housing , billboards, phone booths and security booths , etc. have been applied . According to experts , the first noteworthy is antibacterial gel coat resin . Antimicrobial resistance is an important performance indicator antibacterial gel coat resin , it has a direct impact on the further development and application of antibacterial gel coat resin , the study factors affecting antibacterial properties has very important significance. Composite Materials Science Engineering , Zhejiang University School of inorganic house, and silica as the carrier through a load of metallic silver nano ions Ti02, 3 , on the surface of the silicon dissolved precipitated silica Zn02 and A12 (SOi3), prepared composite inorganic antibacterial agent , and added to the gel coat resin prepared antibacterial gel coat resin . The preparation parameters of antimicrobials affect the antibacterial properties of gel coat resin content when the number and type of preparation and antibacterial gel coat resin. Experimental results show that with the sintering temperature , the rate of antibiotic antibacterial gel coat resin showed first increased and then decreased , the sintering temperature is 1000 ℃ , the highest antibacterial gel coat resin antibacterial rate ; With the extension of milling time , antibacterial gel coat resin antibacterial rate is rising , the milling time is greater than 6:00 antibacterial rate enhancement amplitude decreases.

About UV curing gel coat resin . According to experts, the gel coat resin is an unsaturated polyester resin in a particular species, mainly in the rejection of a covering sheet is formed on a continuous surface of the resin article , a matrix resin or a laminated material provides protection, improved weathering products , corrosion resistance, heat resistance and other properties, and give products a bright, beautiful appearance. UV curing with low pollution, low power consumption, fast curing , high productivity and other advantages . Chemistry and Chemical Engineering , Henan University, with isophthalic acid , phthalic acid and a mixture of both ( between phthalic anhydride molar ratio of 4:1 ) , and a diol ( propylene glycol and diethylene glycol Moore ratio of 4:1 ) , was synthesized three kinds of gel coat resin - inter -UPR, ortho -UPR and mixed -UPR. When the resin is added after the mass fraction of 1% of benzoin ethyl ether as a photoinitiator , can be ultraviolet light cured 3omin . The cured product of acid and alkali resistance , solvent resistance and surface gloss to phthalate resin best . Methods such as infrared spectroscopy to study the UV curing process with its TG-DTA method to study the thermal properties of the cured material was found at 300 ℃ inter -UPR to seniors almost weightless , and ortho -UPR began at about 100 ℃ weightlessness . Further, the light -curable resin with a peroxide in the thermal stability began losing weight , the photo-curable resin on the thermal stability of peroxide -curable resin .

With antifouling unsaturated polyester gel coats have long been developed. U.S. AshlandInc a stain of the present invention unsaturated polyester gel coats , reported stain agent containing an unsaturated polyester gel coat paint for ship applications. Unsaturated polyester gel stain stain coating agent comprising the stain is selected from a 4,5 dichloro-2 - octyl-4 - isothiazolin -3 , cyclopropyl-N a ( a 1 - dimethylethyl tomb ) -6 - ( methylthio ) -1,3,5 - triazine- 2, 4 - diamine , and N [( methyl -dichloro- fluoro ) thio ] phthalimide , or mixtures thereof , the present invention also relates to the preparation of unsaturated polyester gel stain resistant coating . According to experts, the Finnish NesteChemical also studied the low monomer content of unsaturated polyester composition of the compound and its preparation , coating systems for multi- channel gel coat and laminate materials of the kind of unsaturated polyester composition containing : ≥ 1 kinds of high- molecular weight high viscosity unsaturated polyester 10 ~ 90%; 10 ~ 80% ≥ 1 kinds of low molecular weight and low viscosity unsaturated polyester monomer ≥ 1 90 to 30% . For example, 31 parts of glycidyl from phthalic anhydride, trimethylolpropane , glycerol methacrylate , and an unsaturated acid polyesters prepared with 15 parts of maleic anhydride , diethylene glycol, benzyl alcohol and 2 ethyl alcohol has been obtained by an unsaturated polyester , 31 parts of maleic anhydride , diethylene glycol, ethylene glycol . Diethylene glycol, glycidyl methacrylate and the obtained unsaturated polyester , and a mixture of 23 parts of styrene , a cured product of the cured tensile strength of 66MPa, a bending strength of 108MPa, heat distortion temperature was 64 ℃.
