2. Description of the Related Art Heretofore, various methods for press-molding products such as bathtubs and counters having a marble-like appearance by using a resin concrete material in a concave shape and a convex shape have been proposed and implemented (for example, Japanese Patent Laid-Open Publication No. Sho. 56-117641,
JP-B-56-43201, JP-A-58-90921, 58-90922,
Japanese Patent Publication No. 56-220, etc.). As the base resin constituting the artificial marble in the conventional manufacturing method of the product, for example, a heat-resistant unsaturated polyester resin or epoxy resin obtained by mixing and kneading an inorganic filler or a fibrous reinforcing material is used. In general, a gel coat layer is provided on the surface of the base layer resin in order to provide surface gloss and smoothness.

By the way, when a product such as a bath is molded by press molding using the above-mentioned resin, the resin in the mold is heated to a molding temperature of 60 to 120 ° C. during press molding. The gel coat layer resin and the base layer resin in the inside may cause fine irregularities on the surface of the gel coat layer or may cause cracks in the product. It was customary to add shrinkage inhibitors such as.

However, the more the shrinkage preventing agent such as polystyrene resin is added, the more the transparency of the resin decreases, and unsaturated polyester resin or epoxy resin having excellent transparency is used for the gel coat layer and the base layer. Also, the finished product has an appearance that is far from transparent, so for example, even if a backing layer having a marble-like pattern is laminated, this pattern can hardly be seen through, and the product has the desired marble-like deep appearance. There was a problem that I could not do.

Therefore, when molding a marble-like product from which the surface pattern of the backing layer can be seen through,
As the resin for the gel coat layer and the resin for the base compound, a methacrylic resin excellent in physical properties such as transparency and impact resistance is being used in place of the above unsaturated polyester resin and epoxy resin (for example, JP-A-3-41114).

[Problems of the prior art] However, methacrylic resin has a poor affinity with other fillers, and it may take a very long time to process during molding and curing, resulting in poor productivity, and the resin itself is an unsaturated polyester resin. In addition to being expensive, the product is very expensive.

In view of the above-mentioned drawbacks, the present invention is excellent in transparency without using a methacrylic resin having excellent transparency and is excellent in transparency even though an unsaturated polyester resin is used as a gel coat layer. It was made for the purpose of obtaining a method for producing a marble-prepared product which can be sufficiently seen through even if a layer having an arbitrary colored pattern is laminated on the layer and which is excellent in moldability.

In the present invention, the gel coat layer is provided on the convex surface, and the compound for molding the product is supplied on the gel coat layer as in the conventional case. Further, in the present invention, an unsaturated polyester resin is used as the resin for the base layer compound. The unsaturated polyester resin in the present invention includes saturated dibasic acids such as phthalic anhydride, isophthalic acid, adipic acid, sebacic acid, tetrahydrophthalic anhydride, and het anhydride, and unsaturated unsaturated compounds such as maleic anhydride, fumaric acid, and itaconic acid. Unsaturated alkyds obtained by the esterification reaction of dibasic acids and glycols such as ethylene glycol, propylene glycol, diethylene glycol, 1.4-butanediol, 1.3-butanediol, neopentyl glycol and hydrogenated bisphenol A are diallyl. A liquid resin dissolved in a phthalate monomer or a triallyl cyanurate monomer is used.

A diallyl phthalate polymer is used as the allyl prepolymer. The diallyl prepolymer is a white powder which is obtained by polymerization of diallyl orthophthalate, diallyl isophthalate or diallyl terephthalate and has a softening point in the range of about 60 to 120 ° C. Polyester resins have many advantages over other materials, but have the drawback of shrinking upon curing, as described above.

On the other hand, a diallyl phthalate resin using an allyl-based prepolymer has a small degree of shrinkage during polymerization and has a good transparency and a refractive index close to that of glass. Therefore, if this allyl-based prepolymer is added to the above unsaturated polyester resin, the effect of imparting excellent transparency can be obtained at the same time as the prevention of shrinkage, which is commensurate with the addition, and as a result, the backing layer should be a layer that is fully transparent. Is possible.

In order to provide a gel coat layer on the convex surface, the gel coat resin powder is uniformly dispersed on the mold surface heated to a temperature of 70 to 100 ° C. to soften and melt it, or an allyl prepolymer dissolved in a solvent and The unsaturated polyester is applied uniformly. Then, when the viscosity becomes appropriate, glass fibers are mounted as needed. A base compound containing 10 to 35 parts by weight of an allyl-based prepolymer in a liquid unsaturated polyester resin is supplied onto the placed glass fiber layer.

In the above, the purpose of adding the allyl prepolymer is to prevent the shrinkage of the unsaturated polyester resin and to prevent the transparency from being impaired. If the addition amount of the allyl-based prepolymer is less than 10 parts by weight, sufficient shrinkage-preventing effect and moldability cannot be obtained, and if it is more than 35 parts by weight, it is convenient in terms of the above-mentioned shrinkage-preventing effect There is no improvement and it is economically disadvantageous. After the base compound is supplied, a backing layer resin, to which an optional color pigment is further added, is supplied onto the layer.

Next, the concave mold is placed and heated and compressed at a temperature of 60 to 120 ° C. and a compression pressure of 2 to 200 kg / cm 2 . The above temperature and pressure conditions are such that at temperatures lower than 60 ° C it takes too long for the resin to completely cure, and at temperatures higher than 120 ° C styrene and other substances are scattered during gel coat formation, which causes problems with quality and the like. May occur. Therefore, the above temperature range is the proper temperature. The compression pressure for the proper temperature is
2-20 kg / cm 2 is sufficient.

The base compound layer formed by the polymerization of the allyl-based prepolymer is transparent, and since the refractive index is similar to that of the glass fiber mat layer of the intermediate layer, no shadow of the fiber is recognized and the gel coat layer is formed. Since it is a very thin layer, both layers form a layer having excellent transparency.
Therefore, the coloring of the backing layer can be seen clearly on the surface,
A marble-like product with a very deep feeling is formed. In addition, a filler, a curing agent, a pigment, and glass fiber are added to the unsaturated polyester resin as needed.

By these, the transparency and the deep color tone can be completely satisfied.
