とにある。However, although the support layer has a sufficient supporting effect on the gel coat layer, it contains reinforcing fibers as a main material in addition to the reactive curable resin. There is a problem that the gel coat layer needs to be thickened because the resin between the two shrinks during curing to become uneven, which adversely affects the surface of the gel coat layer. Therefore, an object of the present invention is to provide an FRP molded product having a smooth surface even when the thickness of a gel coat layer is reduced while maintaining heat retention in view of the above problem.

高い。(Function 1) According to the above-mentioned configuration 1, the balloon-shaped lightweight filler exhibits heat insulating properties due to the space confined therein, and has a substantially spherical shape, so that it has a reaction hardening property. By integrating with the resin and laminating directly on the back surface of the gel coat layer, there is no adverse effect such that unevenness due to the reinforcing fiber appears on the surface of the gel coat layer unlike a conventional FRP molded product. If the lightweight filler is less than 20 parts by weight with respect to 100 parts by weight of the reaction curable resin, the heat insulating property is inferior, and if it is more than 100 parts by weight, the heat insulating layer becomes brittle. Although it is preferable in performing spray molding such as an up method, a heat insulation layer having good heat insulation and strength can be formed at 20 to 100 parts by weight in consideration of brush coating. In addition, the average thickness of the insulation layer
If it is smaller than 2.0 mm, the heat retention is inferior and 5.0 m
If it is larger than m, it takes a lot of time and effort for molding.
A thickness of 0 mm is practical, but 2.0-5.0 mm
At the average thickness, both heat retention and moldability can be improved. ( Function 2 ) According to the above configuration 2 , if the lightweight filler is at least one selected from the group consisting of a shirasu balloon, a ceramic balloon, a glass balloon, a silica balloon, a carbon balloon, a phenol balloon, and an alumina balloon, the heat insulating property is obtained. Of course, it has high strength and heat resistance. Above all, a shirasu balloon is inexpensive and has an uneven surface shape, so that it is well compatible with the reaction curable resin and has a large bonding strength, and also has a high supporting strength for the gel coat layer as in the case of the supporting layer. The size is preferably 150 μm because the heat retention is poor if the size is smaller than 10 μm, and the surface smoothness is poor if the size is larger than 300 μm.
When the thickness is 300 μm, the heat retention is large and the smoothness of the gel coat layer is not adversely affected. ( Function 3 ) According to the above configuration 3 , if the reaction curable resin is one selected from the group consisting of an unsaturated polyester resin, a vinyl ester resin, a bisphenol-based polyester resin, and an epoxy resin, heat resistance and water resistance are provided. And high strength.

At 0 kg / square cm, it is nonflammable and has excellent fire resistance and heat insulation. In addition, the shirasu balloon has a good mixing property and adhesiveness with the resin, and not only the balloon absorbs heat generated when the reaction-curable resin is cured, but also bridges the resins, so that shrinkage upon cooling is reduced. Extremely small, preventing sinks and cracks and increasing the product efficiency of the resin. Furthermore,
By mixing the shirasu balloon, the resin is given thixotropy, so that no dripping occurs at the time of coating, a single coating can be made thicker, and a uniform coated surface can be obtained.

As the kind of the granular lightweight filler, a hollow inorganic material or a resin material can be used, but a spherical hollow body is preferably used. Specifically, shirasu balloon, ceramic balloon, glass balloon, silica balloon, carbon balloon, phenol balloon, alumina balloon and the like are used. Above all, a shirasu balloon is preferably used in the present invention because it is inexpensive and has good compatibility with resins and fibers. The average particle diameter of the lightweight filler is preferably 10 to 300 μm, and 30 to 200 μm.
Is more preferred. In other words, if it exceeds this range, not only does it become less compatible with the resin, but if it is less than 10 μm, the heat retention is poor, and if it is more than 300 μm, the smoothness after molding tends to be poor. The amount of the particulate light filler used is, based on the above-mentioned reason, based on 100 parts by weight of the reaction curable resin,
Although it is preferably 20 to 50 parts by weight, about 20 to 100 parts by weight can be used depending on the type of the resin used and the method of forming the layer. If the viscosity increases, the surface tends to be uneven, and molding by the spray-up method is difficult. However, if it exceeds 100 parts by weight, it becomes brittle.

ため、より好ましい。Examples of the reactive curable resin include those containing a resin component such as an unsaturated polyester resin, a vinyl ester resin and an epoxy resin, and a monomer component such as a styrene monomer and an acrylic monomer. The viscosity of such a reaction curable resin can be adjusted by adjusting the amount of the monomer component.
Adjust to 0 poise, more preferably 14 to 40 poise. If it is less than this range, dripping tends to occur and the thickness of the layer tends to be difficult to obtain. More coating materials, wherein at blown to gelcoat layer, the average thickness of the heat insulating layer obtained by the above, from the reason described above, after curing

層の全重量中、３０〜４０重量％が好ましい。[Step of Forming Support Layer] The support layer is formed by a known material and method mainly for the purpose of increasing the overall strength of the FRP molded product. The outline of this step is to form a support layer by applying a coating material mainly composed of a reaction-curable resin and fibers to the surface of the heat insulating layer by spraying or the like, and then curing the resin after the application. Examples of the type of fiber include glass fiber and those obtained by subjecting the fiber to various surface treatments, and any fiber having similar physical properties can be used. The average fiber length of the fiber is 15 to 50
mm, more preferably 25-30.
mm. If it exceeds this range, fluffing tends to increase, and if it is less than this range, the reinforcing effect tends to decrease. The amount of the fiber used depends on the type of the resin used, but is preferably 30 to 40% by weight based on the total weight of the support layer from the viewpoint of the strength of the support layer.

度であることが好ましい。Examples of the reactive curable resin include those containing a resin component such as an unsaturated polyester resin, a vinyl ester resin, and an epoxy resin, and a monomer component such as a styrene monomer and an acrylic monomer. The viscosity of such a reaction curable resin can be adjusted by the amount of the monomer component. The coating material described above is sprayed on the back surface side of the heat insulating layer (the molding procedure is the front surface of the heat insulating layer) in the same manner as in the step of forming the heat insulating layer. The average thickness of the support layer obtained after curing is preferably about 1.5 to 2.5 mm.
