Abstract
Description
本発明は、樹脂組成物、成形材料およびその成形品に関する。 The present invention relates to a resin composition, a molding material and a molded product thereof.
シートモールディングコンパウンド（ＳＭＣ）は、熱硬化性樹脂、無機充填剤、増粘剤、硬化剤等を混ぜたペースト（コンパウンド）をガラス繊維に含浸させてシート状とし、熟成処理を行って、半硬化させた成形材料である。このＳＭＣを金型によって加熱・加圧成形することで、成形品が得られる。このような成形品は、優れた耐久性や耐水性、機械的強度等の特性を利用して、浴室機器や貯水槽、浄化槽、建築材、床材、電気部品、車両用材料等として幅広く用いられているが、特に車両用材料、航空機材料等においては軽量化が求められている。 Sheet molding compound (SMC) is made by impregnating glass fibers with a paste (compound) mixed with a thermosetting resin, an inorganic filler, a thickener, a curing agent, etc. to form a sheet, which is aged and semi-cured. It is a molded material. A molded product can be obtained by heating and pressure molding this SMC with a mold. Such molded products are widely used as bathroom equipment, water tanks, septic tanks, building materials, flooring materials, electrical parts, vehicle materials, etc. by utilizing their characteristics such as excellent durability, water resistance, and mechanical strength. However, weight reduction is particularly required for vehicle materials, aircraft materials, and the like.
これらのＦＲＰでは、十分な強度を得る為にガラス繊維を用い、またコスト低減の為に炭酸カルシウム等の無機充填材を添加する場合が多く、その比重は１．７～２．０程度であるが、近年、炭酸ガス削減や燃費向上の要求により、自動車部材・船舶部材・航空機部材を中心に軽量化が求められてきた。 In these FRPs, glass fiber is often used to obtain sufficient strength, and an inorganic filler such as calcium carbonate is often added to reduce the cost, and its specific gravity is about 1.7 to 2.0. However, in recent years, due to the demand for reduction of carbon dioxide gas and improvement of fuel efficiency, weight reduction has been required mainly for automobile parts, ship parts, and aircraft parts.
成形品を軽量化する手法として、中空ガラスビーズ、ガラスマイクロバルーンに代表される中空充填剤（バルーン）を添加する方法が提案されている（例えば、特許文献１参照）。しかしながら、バルーンを添加すると表面平滑性が劣ること、コンパウンド粘度が高くなることによりＳＭＣ製造適性が損なわれる課題があった。 As a method for reducing the weight of a molded product, a method of adding a hollow filler (balloon) typified by hollow glass beads and glass microballoons has been proposed (see, for example, Patent Document 1). However, when a balloon is added, there are problems that the surface smoothness is inferior and the compound viscosity is increased, so that the suitability for SMC production is impaired.
本発明が解決しようとする課題は、製造適性に優れ、優れた表面平滑性を有する低比重の成形品が得られる樹脂組成物、成形材料及びその成形品を提供することである。 An object to be solved by the present invention is to provide a resin composition, a molding material, and a molded product thereof, which can obtain a molded product having excellent production suitability and excellent surface smoothness and a low specific density.

We found that we could obtain it, and completed the present invention.

前記ＳＭＣの製造方法としては、通常のロール、インターミキサー、プラネタリーミキサー、ニーダー、押し出し機などの混合機を用いて、不飽和ポリエステル（Ａ）、水素添加スチレン系熱可塑性エラストマー（Ｂ）、スチレンモノマー（Ｃ）、無機充填材（Ｄ）、ガラスバルーン（Ｅ）、湿潤分散剤（Ｆ）、及び重合開始剤（Ｇ）等の樹脂組成物の各成分を混合分散し、上下に設置されたキャリアフィルムに均一な厚さになるように塗布し、所定の長さにカットされたガラス繊維を、前記上下に設置されたキャリアフィルムの樹脂組成物に挟み込み、次いで、全体を含浸ロールの間に通して、圧力を加えて繊維補強材に樹脂組成物を含浸させた後、ロール状に巻き取るか又はつづら折りに畳んでＳＭＣが得られる。必要に応じて、この後に熟成等を行う。増粘剤を配合した場合は、２５～６０℃の温度で熟成することが好ましい。キャリアフィルムとしては、ポリエチレンフィルム、ポリプロピレンフィルム等を用いることができる。 As a method for producing the SMC, an unsaturated polyester (A), a hydrogenated styrene-based thermoplastic elastomer (B), and a styrene are used in a mixer such as a normal roll, an intermixer, a planetary mixer, a kneader, and an extruder. Each component of the resin composition such as the monomer (C), the inorganic filler (D), the glass balloon (E), the wet dispersant (F), and the polymerization initiator (G) was mixed and dispersed, and placed above and below. The glass fibers applied to the carrier film to a uniform thickness and cut to a predetermined length are sandwiched between the resin compositions of the carrier films placed above and below, and then the whole is sandwiched between the impregnating rolls. After the fiber reinforcing material is impregnated with the resin composition by applying pressure, the fiber reinforcing material is wound into a roll or folded into a zigzag fold to obtain SMC. If necessary, aging is performed after this. When a thickener is blended, it is preferably aged at a temperature of 25 to 60 ° C.

Is molded and a molding pressure of 0.1 to 20 MPa is maintained to cure the molding material, and then the molded product is taken out to obtain a molded product. In this case, in a mold having a share edge, the molding pressure of 1 to 10 MPa is maintained for a specified time of 1 to 2 minutes per 1 mm of the thickness of the molded product at a mold temperature of 120 ° C to 160 ° C, and heat compression molding is performed. The manufacturing method is preferable.

なお、本発明における成形品の比重は、各原料成分の比重及び組成比から求めた計算比重とする。 The specific gravity of the molded product in the present invention is a calculated specific gravity obtained from the specific gravity and the composition ratio of each raw material component.
本発明の成形材料から得られる成形品は、低比重で且つ表面平滑性が優れた成形品が得られることから、浴槽や洗面ボウル等の住宅設備部材に加えて、自動車部品、船体部品、航空機部品等に好適に用いることができる。 Since the molded product obtained from the molding material of the present invention has a low specific density and excellent surface smoothness, in addition to housing equipment members such as bathtubs and wash bowls, automobile parts, hull parts, and aircraft It can be suitably used for parts and the like.
