The present invention relates to a composite material with excellent interlayer bonding strength consisting of a fiber-reinforced thermosetting resin layer and a polyolefin layer. Fiber-reinforced thermosetting resin materials made from unsaturated polyester resin, vinyl ester resin, epoxy resin, etc. and reinforcing fibers are lightweight and have excellent mechanical strength, so they can be used in various industrial products such as water tanks, etc.
It is widely used in housing-related products. However, although these products have sufficient mechanical strength, they lack chemical resistance and hot water resistance against alkaline substances, solvents, and hot water of 80°C or higher, making it difficult to use them for these purposes. Ta. In order to improve these drawbacks, a composite material has been proposed in which a polyolefin such as polypropylene or polyethylene, which has excellent chemical resistance and hot water resistance, is used as the wetted layer and a fiber-reinforced thermosetting resin layer is arranged on the back side. It has been implemented. However, polyolefin and fiber-reinforced thermosetting resin have poor adhesion, and various efforts have been made to improve the adhesiveness of the polyolefin layer. For example, methods such as surface treatments such as corona discharge and electron beam irradiation, and etching treatments using chemicals have been proposed, but these methods still lack adhesiveness and are problematic in practice. In addition, as a method to physically improve adhesive performance, a method has been proposed in which a polyolefin sheet partially impregnated with glass fiber fabric, organic fiber, etc. using a hot roll is reinforced with fiber-reinforced thermosetting resin to obtain a composite material. It has been put into practical use. However, with this method, it is difficult to preform a polyolefin sheet partially impregnated with a fiber material into shapes that vary widely, such as pipes, angles, and boxes, by thermoforming. Welding of polyolefin sheets is necessary to obtain a preform. Therefore, there are disadvantages in that quality variations are likely to occur due to the skill of the welding technique of the worker, stress is likely to be concentrated in the welded area, and production efficiency is also poor. As a result of intensive research aimed at resolving these drawbacks, the inventors have found that by imparting characteristics to the polyolefin layer, a composite material consisting of a fiber-reinforced thermosetting resin layer and a polyolefin layer with excellent interlayer adhesive strength can be obtained. This discovery led to the completion of the present invention. That is, the present invention provides a composite material comprising a fiber-reinforced thermosetting resin layer and a polyolefin layer, wherein the polyolefin layer is composed of (A) polypropylene, (B) a polypropylene copolymer, another olefin polymer, and a filler. To provide a composite material with excellent interlayer adhesive strength, characterized by being made of a mixture with at least one selected one. The polypropylene and polypropylene copolymer used in the present invention are already well-known propylene-based polymers, and the polypropylene refers to a homopolymer of propylene, while the polypropylene copolymer refers to ethylene, butene, etc. whose main component is propylene. A copolymer with olefins such as pentene. In addition, other olefin polymers include
Refers to already well-known olefinic polymers, excluding the polypropylene and polypropylene copolymers mentioned above, such as low-density, medium-density and high-density polyethylene, ethylene-butene copolymers, ethylene-butene copolymers, etc.
These include pentene copolymers and polybutenes. Further, the filler refers to a well-known filler for plastics, such as talc, clay, calcium carbonate, aluminum hydroxide, silica, etc., with talc and calcium carbonate being preferably used. In the polyolefin layer constituting the composite material of the present invention, the mixing ratios of (A) polypropylene, (B) polypropylene copolymer, other olefin polymers, and fillers are usually
0 to 30 parts by weight, 0 to 100 parts by weight, respectively
40 parts by weight and 0 to 100 parts by weight, preferably 5 to 20 parts by weight, 5 to 30 parts by weight and 20 to 80 parts by weight. If the mixing ratio of the above-mentioned polypropylene copolymer and other olefin polymer is small, the adhesion, preformability and composite moldability will be low, and if it is large, the adhesion and stress cracking resistance will be low. Furthermore, if the amount of filler is small, the adhesiveness will be extremely low, and if the amount is large, the sheet formability and impact resistance will be low, which is not preferable. The fiber-reinforced thermosetting resin layer constituting the composite material of the present invention mainly consists of reinforcing fibers and thermosetting resin. Examples of the reinforcing fibers include glass fibers and carbon fibers, and examples of the thermosetting resin include non-carbon fibers. There are saturated polyester resins, vinyl ester resins, epoxy resins, etc. Further, well-known fillers, low-shrinkage agents, pigments, mold release agents, curing agents, and other additives may be mixed into the thermosetting resin layer. When laminating the fiber-reinforced thermosetting resin layer, the reinforcing fibers and thermosetting resin may be mixed on the spot, or SMC (sheet molding compound) or BMC (bulk molding compound) may be used. A molding material in which a compound of reinforcing fibers and a thermosetting resin is mixed in advance, such as a molding compound (molding compound), may also be used. The composite material with excellent interlayer adhesion strength of the present invention can be easily produced by superimposing the material constituting the fiber-reinforced thermosetting resin layer and the material constituting the polyolefin layer (abbreviated as polyolefin material) and heating and pressurizing them. can be obtained. In this case, it is preferable to use a polyolefin material preformed by a commonly used thermoplastic resin molding method such as extrusion molding, vacuum molding, pressure molding, injection molding, or blow molding, if necessary. For example, a box-shaped composite material is produced by preforming a sheet of polyolefin material into a box shape by hot pressure forming such as vacuum forming, and setting the obtained box-shaped product into a mold for molding a thermosetting resin. It is obtained by composite molding, in which a fiber-reinforced thermosetting resin compound such as SMC is placed on top of it and heated and pressed. In normal cases, the heating temperature and molding pressure are
110-160℃, 1-150Kg/ cm2 , preferably
130-145℃, 20-80Kg/ cm2 . In addition, the thickness of the polyolefin layer after preforming is usually in the range of 0.3 to 5.0 mm, preferably in the range of 1.0 to 2.5 mm, considering the balance between composite moldability, chemical resistance, and hot water resistance. . The composite material obtained in this way has excellent chemical resistance and hot water resistance due to the polyolefin layer placed on the liquid contact side, and is also mechanically resistant because it is backed with a fiber-reinforced thermosetting resin with good interlayer adhesion. It also has excellent strength. Since various shapes such as plates, boxes, pipes, and angles can be easily obtained, it can also be used in combination with urethane foam, resin concrete, etc. to create various molded products that have both heat insulation and rigidity. . The present invention will be explained in more detail by showing Examples below. In addition, all parts and percentages in the examples are based on weight. Examples 1 to 11 and Comparative Examples 1 to 3 1.0 mm thick sheet obtained by extrusion molding a polyolefin material into a concave mold (300 mm x 300 mm x 3.5 mm) for MMD (Matted Metal Die) molding. on top of which a continuous glass matte M-
