本発明は、硬質熱可塑性合成樹脂内に芯材補強

される建材用補強硬質合成樹脂成型品の製造方法
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a reinforced hard synthetic resin molded product for building materials, which is suitably used as a building material material, in which a core reinforcing layer is embedded in a hard thermoplastic synthetic resin. It is.
硬質熱可塑性合成樹脂内に芯材補強層を埋込収
蔵させて、硬質熱可塑性合成樹脂成型品の持つ熱
変形，熱収縮の容易な点や、熱的あるいは構造的
強度が低い点などを改善した合成樹脂成型品とし
ては、芯材補強層に鉄板や、金網を用いた物が既
に公知であるが、このような鉄板や、金網を用い
た物は、製造面，コスト面，使用面から次のよう
な問題点を有している。 A core reinforcing layer is embedded in a hard thermoplastic synthetic resin to improve the ease of thermal deformation and shrinkage, as well as low thermal and structural strength, of hard thermoplastic synthetic resin molded products. Synthetic resin molded products using iron plates or wire mesh as the core reinforcing layer are already known, but products using such iron plates or wire mesh are difficult to manufacture, cost, and use. It has the following problems.
すなわち、熱可塑性合成樹脂に対し、異質の材
料となる鉄板や、金網の補強芯を埋込成形するの
で、補強芯の表面に適当な表面処理を施し、且つ
適当な接着剤を塗着する工程上の煩わしさがあつ
た。 In other words, since reinforcing cores such as iron plates or wire mesh, which are different materials, are embedded into thermoplastic synthetic resin, the process involves applying appropriate surface treatment to the surface of the reinforcing cores and applying an appropriate adhesive. The above annoyances bothered me.
また、補強芯が重いので成型品自体かなりな重
量増となり製造コストも高価であつた。 Furthermore, since the reinforcing core is heavy, the weight of the molded product itself increases considerably and the manufacturing cost is also high.
更に、成型品の切断端面に補強芯が露顕し発錆
を誘発して腐食しやすく、しかも補強芯は熱可塑
性合成樹脂とその該表面のみが接着剤等で密着し
ているだけなので構造的にも層間剥離を生じ易い
などの…問題点を有していた。 Furthermore, the reinforcing core is exposed on the cut end of the molded product, causing rust and corrosion. Moreover, the reinforcing core is structurally unstable because only the thermoplastic synthetic resin and its surface are in close contact with each other with adhesive, etc. However, they also had problems such as easy delamination between layers.
そこで、本発明は上記に鑑みて開発されたも

ある。 Therefore, the present invention was developed in view of the above, and is a core reinforcing layer made by impregnating a fibrous base material other than paper with a thermoplastic synthetic resin, and a hard thermoplastic synthetic resin composite integrally molded. The object of the present invention is to provide a method for producing a reinforced hard synthetic resin molded product for building materials, which is characterized by the following, and thereby to obtain a molded product that solves the above-mentioned problems.
以下に添付図を参照しつつ本発明の望ましい実
施例の製造方法について説明する。 A manufacturing method of a preferred embodiment of the present invention will be described below with reference to the accompanying drawings.
まづ、雨樋を例にとつた製造プロセスを第１
図，第２図によつて説明すると、基材調整工程(A)

Nonwoven fabrics, woven fabrics made of polyester fibers, nylon fibers, polyvinyl fibers, etc. alone or in combination,
Processed products such as mats and nets can be used, and it is also possible to polymerize them to form a multilayer structure and increase the thickness. Among these base materials, one is appropriately selected depending on the purpose of use.
熱可塑性合成樹脂含浸工程(B)は、上記工程(A)に
よつて選択された繊維質基材１０を樹脂原料の樹
脂液若しくはエマルジヨン型樹脂液中に含浸する
工程である。 The thermoplastic synthetic resin impregnation step (B) is a step of impregnating the fibrous base material 10 selected in the above step (A) into a resin liquid or an emulsion type resin liquid as a resin raw material.

好ましい。 The aging step (C) is a step of drying the resin component by leaving the impregnated resin liquid at room temperature or under heating. However, in this step (C), heating to soften the resin to some extent improves interlayer adhesion in the subsequent step of welding and integrating the hard thermoplastic resin 2 that forms the outer surface layer. It is preferable.

材補強層１１を連続的に導入する。 In the preforming step (E), the core reinforcing layer 11 is sent to the preforming mold RM to be preformed into a shape corresponding to the shape of a rain gutter, for example, by sending it to the preforming mold RM. In the next mold introduction step (F), a part corresponding to approximately the center of the thickness of the molded product of extrusion molding M, which is assembled with a rigid thermoplastic resin extruder EX and a cross die, is preformed into the shape of a rain gutter. The core reinforcing layer 11 is continuously introduced.

ことができる。 As the hard thermoplastic synthetic resin 2 forming the outer surface layer, PVC, acrylic resin, polycarbonate, modified resins thereof, etc. are used, and the thermoplastic synthetic resin 2 has excellent weather resistance, abrasion resistance, shear strength, tensile strength, impact strength, and the above-mentioned thermoplastic synthetic resin. Considering the compatibility with the resin 12 or depending on the properties required for the surface of the molded product, a single layer of the above-mentioned hard thermoplastic synthetic resin 2 or multiple layers made by polymerizing two or more resins may be used. can be formed into

is as shown in FIG. 3, and if the structure of this hard molded product P is microscopically analyzed, each of the fiber elements constituting the fibrous base material 10 in the core reinforcing layer 11 is As shown in FIG. 4, it is in a state where it is supported by the thermoplastic resin 12 that has been impregnated and solidified, and the thermoplastic resin 12 that has penetrated deeply between each fiber element and solidified is outside. It is welded and integrated with the hard thermoplastic resin 2 coated on the surface layer to form a structure with extremely high bonding strength.

ないので耐久性にも優れたものとなるのである。 Therefore, in the hard molded product P obtained by this manufacturing method, the core reinforcing layer 11 allows the hard thermoplastic resin 2 forming the outer surface layer to elongate in the longitudinal direction and the width direction and to shrink in the same direction due to heat. The core reinforcing layer 11
It is characterized by good adhesion at the interface between the two layers and the synthetic resin outer surface layer, making it difficult for interlayer peeling to occur. Furthermore, since the fibrous base material 10 is used as a reinforcing core, it is lighter and cheaper than iron plates or wire meshes, and in addition, rust does not occur even if the core material is exposed from the cut end surface. Since it does not induce this, it has excellent durability.

ることができるのである。 As described above, according to the manufacturing method of the present invention, there is no need to use iron plates, wire mesh, etc., and there is no need for a coating process. Since the two are welded and integrated, the adhesion between the two is good. Furthermore, since the hard thermoplastic synthetic resin is compositely integrated after the core reinforcing layer is preformed, there is no need to mold it into a shape that matches the shape of the molded product after the integration.
The two are completely integrated in close contact with each other, making it possible to obtain molded products for building materials that do not cause delamination even when molded products have various shapes.

It goes without saying that other building materials can also be produced in the same way, and especially for molded products such as pipes, a method may be adopted in which the thermoplastic resin of the outer surface layer is coated only on the outer peripheral surface.

Processes such as dipping are also possible, and a molding method that takes advantage of the characteristics of the molded product depending on the shape, size, etc. of the molded product to be obtained can be selected as appropriate.
最後に、本発明で雨樋を製造する場合を例にと
