(Comparative Example 3)
40 parts of the vinyl ester resin (1) obtained in Reference Example 1 and 10 parts of the air-drying unsaturated polyester resin (2) obtained in Reference Example 2 were mixed with methacrylic monomer BG (1,3-butylene glycol dimethacrylate, new Add 30 parts of flash point (Cleveland 100 ° C or higher) manufactured by Nakamura Chemical Co., Ltd. and 30 parts of methacrylic monomer FA512MT (dicyclopentenyloxyethyl methacrylate, Hitachi Chemical Co., Ltd., flashpoint (Cleveland) 100 ° C or higher) and heat in advance Then, the resin (1) and (2) that were easily dissolved were diluted and dissolved with the methacrylic monomer to obtain a radical polymerizable resin composition (1). To 100 parts of this radical polymerizable resin composition (1), 0.5 part of 6% cobalt naphthenate (manufactured by Dainippon Ink and Chemicals) as a curing accelerator, 0.2 part of dimethylaniline, Aerosil # 200 (as thixotropic agent) Nippon Aerosil Co., Ltd.) 1 part, an antifoaming agent and an inhibitor were added and prepared to obtain a resin composition (A) to which thixotropy was imparted. As a radical curing agent, 1.0 part of Parmek N (manufactured by Nippon Oil & Fats Co., Ltd.) is blended, and 450 g / m 2 chopped strand mat (manufactured by Nittobo Co., Ltd.) is used. Then, the resin composition provided with thixo was applied from above, the bubbles adhering to the chopped strand mat were removed using an impregnation roller, and so-called hand lay-up lamination was performed. On top of that, a chopped strand glass mat was similarly placed, and this operation was repeated to carry out hand lay-up lamination molding so that the glass mat had three layers, and cured to obtain an FRP molded product having a thickness of 3 mm. .
(Example 2)
After adding 0.3 parts of ethylene urea to 100 parts of the resin composition (A) obtained in Comparative Example 3 , the resin composition (B) was obtained by heating and dissolving. Using this resin composition, the same operation as in Comparative Example 3 was performed to obtain an FRP molded product.
(Comparative Example 1)
A resin composition was obtained in the same manner as in Comparative Example 3 except that 65 parts of the unsaturated polyester resin (3) obtained in Reference Example 3 was diluted with 35 parts of styrene. In this resin composition, an irritating odor derived from styrene (ceta closed flash point 31 ° C.) was observed.
This resin composition was cured to prepare a laminated plate and a cast plate. The amount of formaldehyde volatilized from the laminate was confirmed to be 0.35 mg / L or more. In addition, the styrene emission rate was over-detected because the peak derived from styrene was too large.
(Comparative Example 2)
Except not using the air-drying polyester resins of Comparative Example 3, the same operation as in Comparative Example 3, followed by laminate to prepare a cast plate.
The resulting laminate had a sticky surface even after 8 hours.
[Measurement method and evaluation criteria]
About this radically polymerizable resin composition and a molded article obtained using the same, air drying property, formaldehyde emission amount, styrene volatilization amount and water resistance were measured and evaluated. The measurement method and evaluation criteria are as follows. The results of Example 2 and Comparative Examples 1 to 3 are shown in Table-1.
