Abstract

A resin concrete product suitable for road surfacing bodies and the like, which comprises a laminate which is integrally formed by joining a first compact, which is composed of a first aggregate and a first resin, to a second compact which is composed of a second aggregate and a second resin. One of the aggregates can be composed of elastic bodies such as rubber chips or the like, and the other of the aggregates can be composed of rigid bodies such as rock or the like. Both of the resins can be thermosetting or one of the resins can be thermosetting and the other of the resins can be thermoplastic. A binding property of joined portions in the laminate is enhanced by a cross-linking reaction between the resins, engagement of irregularities themselves, and application of adhesives. The product constructed to have the irregularities themselves engaged with one another is obtained by forming recesses in the first compact and then integrally forming the first compact and the second compact with a resin mixture, which makes the second compact, pushed into the recesses.

Description

明 細 書 レジンコ ンク リー 卜製品およびその製造方法 技術分野  Description Resin concrete products and manufacturing method
本発明は、 レジンコ ンク リー卜製品およびその製造方法に関する。 背景技術  The present invention relates to a resin concrete product and a method for producing the same. Background art
骨材をバイ ンダである合成樹脂で相互に結合してなるレジンコ ンク リー卜製品の例として、 床面、 歩道、 公園、 広場等の舗装を目的とし て敷設される、 互いに結合された 2つの成形体または成形層からなる 舗装板がある。 前記舗装板の 2つの成形層は、 歩行時の衝撃緩和に役 立つ弾性層と、 前記弾性層の荷重負荷時の曲がりを防止するための支 持層とからなる。  As an example of a resin concrete product in which aggregate is mutually bonded with a synthetic resin as a binder, two resin bonded products that are laid for the purpose of paving floors, sidewalks, parks, plazas, etc. There is a pavement board consisting of a molded body or a molded layer. The two formed layers of the pavement board are composed of an elastic layer that helps alleviate the impact during walking, and a support layer that prevents the elastic layer from bending when a load is applied.
前記弾性層と前記支持層とは、 それぞれ、 ゴムチップのような弾性 粒状物からなる骨材と、 砂、 砂利、 砕石等の岩石の細片のような剛性 粒状物とからなる骨材とを有し、 これらのバイ ンダは両層に共通の熱 硬化性樹脂からなる。  The elastic layer and the support layer each have an aggregate made of an elastic granular material such as a rubber chip, and an aggregate made of a rigid granular material such as a small piece of rock such as sand, gravel, and crushed stone. However, these binders are made of a thermosetting resin common to both layers.
前記 2つの成形層からなる舗装板は、 前記剛性粒状物と前記熱硬化 性樹脂との混合物の層の上に、 前記弾性粒状物と前記熱硬化性樹脂と の混合物の層を重ね合わせ、 これらを加熱、 硬化させることによ り得 られる。 両混合物の層は共通の熱硬化性樹脂をバイ ンダとしているた め、 両層中のバイ ンダはこれらの境界で混じり合い、 硬化するとき、 両層を接合する。  The pavement board composed of the two molded layers is obtained by superposing a layer of a mixture of the elastic granular material and the thermosetting resin on a layer of a mixture of the rigid granular material and the thermosetting resin, It is obtained by heating and hardening. Since the layers of both mixtures have a common thermosetting resin as binder, the binders in both layers mix at these boundaries and join the two layers when they cure.
ところで、 共通の合成樹脂は、 両層の相互結合の点で最適である。 しかし、 両層における骨材相互の結合力および両層の性能の点で最適 であるとは限らない。 例えば、 前記舗装板の共通のバイ ンダと してポ リ ウレタン樹脂が使用されているが、 前記ポリ ウレタン樹脂は、 前記 ゴムチップを強固に結合するこ とができ、 また、 その硬化物が柔軟性 を有するために前記ゴムチ ップは相互に弾性的に相対変位可能であ り、 これが前記弾性層の弾性変形性を増大させる。 しかし、 反面、 前 記支持層における剛性粒状物相互の弾性的な相対変位を許し、 これが 前記支持層の剛性を低下させる。 By the way, a common synthetic resin is optimal in terms of mutual bonding of both layers. However, it is optimal in terms of the bonding strength between aggregates in both layers and the performance of both layers. Is not always the case. For example, a polyurethane resin is used as a common binder for the pavement board. The polyurethane resin can firmly bond the rubber chip, and the cured product is flexible. Due to this, the rubber chips can be relatively elastically displaced relative to each other, which increases the elastic deformability of the elastic layer. However, on the other hand, the rigid granular material in the support layer allows elastic relative displacement between each other, which lowers the rigidity of the support layer.
そこで、 前記弾性層および前記剛性層のそれぞれに異なるバイ ンダ を選択して両層を成形するこ とが考えられる。 しかし、 異種のバイ ン ダは共通のバイ ンダのような接合媒体にはならない。 このこ とは、 前 記舗装板に限らず、 互いに接合された 2つの成形体からなる他のレジ ンコ ンク リー ト製品においても同様である。  Therefore, it is conceivable to select a different binder for each of the elastic layer and the rigid layer to form both layers. However, different kinds of binders do not become bonding media like common binders. This applies not only to the above-mentioned pavement board, but also to other resin-concrete products composed of two molded bodies joined to each other.

And a second molded body having a convex portion received in the concave portion, wherein a part of the aggregate defining the peripheral surface of the convex portion is received in a gap between the aggregates defining the wall surface of the concave portion. As a result, the first and second molded bodies are connected to each other.

また、 前記第 1および第 2の成形体の一方の合成樹脂を熱可塑性樹 脂とし、 他の一方の合成樹脂を熱硬化性樹脂とすることができる。  Further, one of the first and second molded bodies may be a thermoplastic resin, and the other synthetic resin may be a thermosetting resin.

発明を実施するための最良の形態  BEST MODE FOR CARRYING OUT THE INVENTION
図 1 を参照する と、 2つの成形層 1 2， 1 4を有する舗装板 1 〇 (図 1 、 図 2および図 3 ) からなるレジンコ ンク リ ー ト製品の製造ェ 程が示されている。  Referring to FIG. 1, there is shown a process for manufacturing a resin concrete product comprising a pavement plate 1 having two formed layers 12 and 14 (FIGS. 1, 2 and 3).
この製造工程において、 型枠 1 6に、 骨材とそのバイ ンダとを混合 してなる第 1 の混合物 1 8および第 2の混合物 2 0を順次に層状に入 れる。  In this manufacturing process, a first mixture 18 and a second mixture 20 each obtained by mixing an aggregate and a binder are sequentially put into a mold 16 in a layer form.
図示の例では、 型枠 1 6への第 1 および第 2の混合物 1 8 , 2 0の 投入場所間の移動およびその後の製造工程間の移動を部分的にベル ト コ ンペャ 2 2を用いて行ない、 また、 部分的に手動によ り行なう。 第 1 の混合物 1 8が投入された型枠 1 6は、 矢印 2 4で示す工程ま たは矢印 2 6で示す工程を経て、 第 2の混合物 2 0の投入場所に運ば れる。  In the illustrated example, the movement of the first and second mixtures 18 and 20 into the mold 16 between the charging locations and the subsequent movement between the manufacturing processes are partially performed using the belt conveyor 22. And partially manually. The mold 16 into which the first mixture 18 has been charged is transported to a place where the second mixture 20 is to be charged through a step indicated by an arrow 24 or a step indicated by an arrow 26.
矢印 2 4で示す工程は、 第 1 および第 2の混合物 1 8 , 2 0力 互 いに接するときに架橋反応をする異種の熱硬化性樹脂 （例えば、 ェポ キシ樹脂およびポリ アミ ド樹脂の混合液と、 ポリ ウ レタン樹脂液との 組み合わせ、 ポリエステル樹脂液とポリ ウレタン樹脂液との組み合わ せ等） を前記バイ ンダとする場合に適し、 矢印 2 6で示す工程は第 1 および第 2の混合物 1 8， 2 0がこれらの合成樹脂以外の異種の合成 樹脂を前記バイ ンダとする場合に適する。 The step indicated by arrow 24 is a process in which different types of thermosetting resins (for example, epoxy resins and polyamide resins) that undergo a cross-linking reaction when they come into contact with the first and second mixtures 18, 20. Combination of mixed liquid and polyurethane resin liquid, Combination of polyester resin liquid and polyurethane resin liquid Is used when the first and second mixtures 18 and 20 are made of different kinds of synthetic resins other than these synthetic resins. Suitable for.
いずれの工程においても、 第 1 の混合物 1 8中の骨材 2 8 (図 2 ) と して、 砂、 砂利、 砕石等を含む岩石の細片、 プラスチッ ク片、 金属 片のような剛性粒状物を用い、 また、 第 2の混合物 2 ◦中の骨材 3 0 と してゴムチップ、 コルクチップのような弾性粒状物を用いる。 前記 剛性粒状物は成形層 1 2 に剛性を与え、 また、 前記弾性粒状物は成形 層 1 4に弾性を与える。 図示の例では、 骨材 2 8および骨材 3 0は、 それぞれ、 3〜 5 mmおよび 1〜 5 mmの粒径を有する。  In each case, the aggregates 28 in the first mixture 18 (Fig. 2) include rigid granules such as rock, sand, gravel, crushed stones, rock fragments, plastic fragments, and metal fragments. In addition, elastic particles such as rubber chips and cork chips are used as aggregates 30 in the second mixture 2. The rigid granules give rigidity to the molding layer 12, and the elastic granules give elasticity to the molding layer 14. In the illustrated example, aggregate 28 and aggregate 30 have a particle size of 3-5 mm and 1-5 mm, respectively.
また、 前記エポキシ樹脂およびポリ アミ ド樹脂の混合液と、 前記ポ リエステル樹脂液とは、 それぞれ、 前記岩石の細片の相互結合に特に 適し、 大きい結合強度を付与する。 同様に、 前記ポリ ウ レタ ン樹脂液 は、 前記ゴムチップの相互結合に特に適し、 大きい結合強度を付与す る。  In addition, the mixed solution of the epoxy resin and the polyamide resin and the polyester resin solution are particularly suitable for mutual bonding of the rock fragments, respectively, and provide a large bonding strength. Similarly, the polyurethane resin liquid is particularly suitable for the mutual bonding of the rubber chips, and provides a large bonding strength.
さらに、 前記第 1 および第 2の各混合物中の合成樹脂は骨材を互い に空隙 3 2 (図 2 ) をおいて結合するに足る量に設定する。 一例を 示すと、 骨材 2 8 ： 前記混合液 （エポキシ樹脂 +ポリ アミ ド樹脂） 二 1 0 0重量％ : 1 0重量％ ( 5重量％ + 5重量％) であり、 また、 骨 材 3 ◦ ： —液性ポリ ウ レタ ン樹脂液 = 1 0 0重量％ ： 1 ◦重量％であ る。 前記空隙は、 成形によ り得られる舗装板 1 0に通気性および透水 性を与える。  Further, the amount of the synthetic resin in each of the first and second mixtures is set to an amount sufficient to combine the aggregates with a gap 32 (FIG. 2). For example, the aggregate 28: the mixed solution (epoxy resin + polyamide resin) 210% by weight: 10% by weight (5% by weight + 5% by weight), and the aggregate 3 ◦: —liquid polyurethane resin liquid = 100% by weight: 1% by weight. The voids give the pavement board 10 obtained by molding air permeability and water permeability.
先ず、 工程 2 4を経る例について説明する。 工程 2 4は、 第 1 の混 合物 1 8が入れられた型枠 1 6を第 2の混合物 2 0の投入場所に移動 するこ とを内容とする。  First, an example through step 24 will be described. The step 24 includes moving the mold 16 containing the first mixture 18 to a place where the second mixture 20 is charged.
第 2の混合物 2 0を第 1 の混合物 1 8上に重ね入れた後、 型枠 1 6 をベル ト コ ンペャ 2 4で運搬する間に ドクターナイフ （図示せず） の ような器具を用いて第 2の混合物 2 0の表面を平らにする。 次いで、 型枠 1 6の開口とほぼ同形でありかつ該開口に嵌合可能であるプレー 卜 3 4を第 2の混合物 2 ◦の層の上に載せる。 After overlaying the second mixture 20 on the first mixture 18, the form 16 The surface of the second mixture 20 is flattened using an instrument such as a doctor knife (not shown) while transporting the second mixture 20 with a belt conveyor 24. Next, a plate 34 having substantially the same shape as the opening of the mold 16 and capable of being fitted into the opening is placed on the layer of the second mixture 2 °.
次に、 手動にて、 プレー ト 3 4が被された型枠 1 6をベル ト コ ンペ ャ 2 4からブレス装置 3 6に移し、 プレス装置 3 6の作動力をプレー 卜 3 4に及ぼす。 これによ り、 型枠 1 6内の両混合物 1 8 , 2 0を加 圧する。  Next, the form 16 covered with the plate 34 is manually transferred from the belt conveyor 24 to the breathing device 36, and the operating force of the press device 36 is applied to the plate 34. . Thereby, both the mixtures 18 and 20 in the mold 16 are pressurized.
プレス装置 3 6による加圧操作の解除前または解除直後、 適当な器 具 （図示せず） を用いて、 プレー ト 3 4が上昇しないよう にこれを 押さえる。 これによ り、 両混合物 1 8 , 2 0の加圧状態を維持する。 次いで、 加圧状態を維持された両混合物を含む型枠 1 6をプレス装置 3 6から取り出す。  Before or immediately after the pressurizing operation by the press device 36 is released, the plate 34 is pressed by a suitable device (not shown) so as not to rise. As a result, the pressurized state of both the mixtures 18 and 20 is maintained. Next, the mold 16 containing both mixtures maintained in a pressurized state is taken out from the press device 36.
なお、 レジンコ ンク リー 卜製品の用途によっては、 両混合物 1 8 , 2 0を加圧するこ となく 、 両混合物が入れられた型枠 1 6を次の加熱 工程に移行することもできる。  Note that, depending on the application of the resin concrete product, the mold 16 containing both mixtures can be transferred to the next heating step without pressurizing both the mixtures 18 and 20.
加圧状態を維持された両混合物が入れられた型枠 1 6が、 好ましく は、 複数個そろった後、 これらを加熱炉 3 8のような加熱手段に入 れ、 一時に加熱する。 加熱は、 例えば、 炉内温度 150 〜 200°C下で約 1 0分間行なう。  Preferably, a plurality of molds 16 containing both mixtures maintained in a pressurized state are put together, and these are put into a heating means such as a heating furnace 38 to be heated at a time. The heating is performed, for example, at a furnace temperature of 150 to 200 ° C for about 10 minutes.
型枠 1 6の加熱によ り、 その内部の第 1および第 2の混合物 1 8 , 2 0が加熱され、 両混合物中の熱硬化性樹脂液がそれぞれ硬化する。 この例に代えて、 両混合物 1 8 , 2 0の加熱を、 ブレス装置 3 6に て両混合物を加圧する間に前記プレス装置に内蔵された加熱手段 （図 示せず） を介して行なう こ とができる。  Due to the heating of the mold 16, the first and second mixtures 18 and 20 inside are heated, and the thermosetting resin liquids in both the mixtures are cured respectively. Instead of this example, the heating of both the mixtures 18 and 20 is performed via heating means (not shown) built in the pressing device while both the mixtures are pressurized by the breathing device 36. Can be.
前記エポキシ樹脂の硬化剤であるポリ アミ ド樹脂の一部と、 ポリ ウ レタ ン樹脂の一部とは両混合物 1 8 , 2 0の境界で接するとき、 前記 ポリ アミ ド樹脂のァミノ基と前記ポリ ウレタ ン樹脂のィ ソシァネ一 卜 基とが架橋反応を起こす。 残りのポリ アミ ド樹脂は前記エポキシ樹脂 の硬化に関与し、 前記エポキシ樹脂は骨材 2 8を相互に結合する。 ま た、 ポリ ウレタ ン樹脂は骨材 3 0を相互に結合する作用をなし、 空気 中の水蒸気 （湿気） との反応によ り硬化を促進される。 A part of a polyamide resin which is a curing agent for the epoxy resin, When a part of the urethane resin is in contact with the boundary between the two mixtures 18 and 20, a cross-linking reaction occurs between the amino group of the polyamide resin and the isocyanate group of the polyurethane resin. The remaining polyamide resin participates in the curing of the epoxy resin, which bonds the aggregates 28 together. Polyurethane resin also acts to bind aggregates 30 to each other, and accelerates curing by reacting with water vapor (moisture) in the air.
この架橋反応によって生じた網目状の硬化物質 4 0 (図 2 ) は、 前 記エポキシ樹脂およびポリ アミ ド樹脂の混合液と、 前記ポリ ウレタ ン 樹脂液との双方に連なるこ とから、 加熱後、 この硬化物質 4 0 によ り、 両成形層 1 2 , 1 4がー体に結合される。  The network-like cured substance 40 (FIG. 2) generated by this crosslinking reaction is connected to both the above-mentioned liquid mixture of epoxy resin and polyamide resin and the above-mentioned polyurethane resin liquid. By the use of the cured material 40, the two molded layers 12 and 14 are bonded to the body.
後者の組み合わせの例では、 互いに接するポリエステル樹脂液の一 部とポリ ウレタン樹脂液の一部とが接するとき、 ポリエステル樹脂の 水酸基と前記ポリ ウ レタ ン樹脂のイ ソシァネー 卜基とが架橋反応を起 こす。 前記ポリエステル樹脂液の残りおよび前記ポリ ウレタン樹脂液 の残りはそれぞれ骨材を結合する糊の作用をなす。  In the latter combination example, when a part of the polyester resin liquid and a part of the polyurethane resin liquid that come into contact with each other come into contact with each other, a cross-linking reaction occurs between the hydroxyl group of the polyester resin and the isocyanate group of the polyurethane resin. Rub The remainder of the polyester resin liquid and the remainder of the polyurethane resin liquid each serve as a glue for binding the aggregate.
加熱を終了した後、 加熱炉 3 8から各型枠 1 6を取り出し、 ベル ト コ ンべャ 2 4に載せて運搬し、 所定位置で脱型する。 脱型の際、 プ レー 卜 3 8を取り外し、 好ましく は、 型枠 1 6の底に開けた孔に例え ば液圧ジャ ッ キのピス ト ンロ ッ ドのようなロ ツ ド 4 2を挿入し、 成形 品を押し上げて該成形品と型枠 1 6 との付着を断つ。  After the heating is completed, each mold 16 is taken out of the heating furnace 38, placed on a belt conveyor 24, transported, and demolded at a predetermined position. When removing the mold, remove the plate 38 and preferably insert a rod 42, such as a hydraulic jack piston rod, into the hole formed in the bottom of the formwork 16. Then, the molded product is pushed up to cut off the adhesion between the molded product and the formwork 16.
プレー ト 3 8および型 1 2は、 それぞれ、 清掃後、 ベル ト コ ンべャ 4 3 , 4 5によ りプレー 卜 3 8を型枠 1 6に取り付ける位置と、 第 1 の混合物 1 8の投入箇所とにそれぞれ運ばれる。  After cleaning, the plate 38 and the mold 12 respectively have a position where the plate 38 is attached to the formwork 16 by the belt conveyors 43 and 45 and a position where the first mixture 18 is formed. It is transported to the loading point.
次に、 工程 2 6を経る例について説明する。 工程 2 6は、 型枠 1 6 を第 2 の混合物 2 0の投入場所に移動するに先立ち、 型枠 1 6内の 第 1 の混合物 （塊） 1 8を加圧し、 混合物 1 8に上方に解放する少な 1 〇 Next, an example through step 26 will be described. In step 26, the first mixture (block) 18 in the mold 16 is pressurized before the mold 16 is moved to the place where the second mixture 20 is charged, and the mixture 18 is moved upward. Little to release 1 〇
く とも 1 つの穴 4 4を形成するこ とを内容とする。 混合物 1 8の加圧 は、 ブレス装置 3 6 と同様のプレス装置 4 6を用いて行なう こ とがで きる。 得よう とするレジンコ ンク リー ト製品に応じて、 加圧を不要と し、 また、 非加圧下の第 1 の混合物の塊 1 8に例えば棒を突き刺して 穴を形成するこ とができる。 At least one hole 4 4 shall be formed. Pressurization of the mixture 18 can be performed using a press device 46 similar to the breath device 36. Depending on the resin concrete product to be obtained, pressurization is not required, and a hole can be formed by piercing, for example, a rod into the first mixture mass 18 under non-pressurization.
穴 4 4は、 例えば 4 0 mm厚さの成形層 1 2および 1 5 mm厚さの成形 層 1 4を有しかつ一片の長さがほぼ 3 0 cmの正方形の平面形状を有す る舗装板 1 0を得る場合、 好ましく は、 その直怪および深さ寸法をそ れぞれ 1 0 mmおよび 1 5 mmに設定し、 また、 穴 4 4の相互間隔を 2 0 〜 3 O mmに設定する。 穴 4 4は、 第 1 の混合物 1 8の層を貫通しない ものであっても良い。  The hole 44 is, for example, a pavement having a 40 mm thick forming layer 12 and a 15 mm thick forming layer 14 and a square planar shape having a piece length of approximately 30 cm. When obtaining plate 10, preferably, its straight and depth dimensions are set to 10 mm and 15 mm, respectively, and the distance between holes 44 is set to 20 to 3 O mm. I do. The holes 44 may not penetrate the layer of the first mixture 18.
プレス装置 4 6は、 穴 4 4を形成するための複数の突起を有する、 型枠 1 6の開口に嵌合可能のプレス板 4 8を有する。 型枠 1 6内の混 合物 1 8にプレス板 4 8を押しつけることによ り、 混合物 1 8が圧縮 され、 複数の穴 4 4が形成される。 言うまでもなく 、 混合物 1 8を圧 縮するこ となしに複数の穴 4 4のみを開ける場合、 ブレス装置 4 6は 不要である。  The press device 46 has a press plate 48 having a plurality of projections for forming the holes 44 and capable of fitting into the opening of the mold 16. By pressing the press plate 48 against the mixture 18 in the mold 16, the mixture 18 is compressed and a plurality of holes 44 are formed. Needless to say, if only a plurality of holes 44 are to be made without compressing the mixture 18, the breathing device 46 is unnecessary.
第 1 の混合物 1 8 に穴 4 4を開けた後、 型枠 1 6を移動し、 型枠 1 6内の第 1 の混合物 1 8の層上にさらに第 2の混合物 2 0を重ね入 れる。 この時、 第 1 の混合物 1 8の穴 4 4に第 2の混合物 2 0を押し 入れる。 その後の操作は、 工程 2 4を経る例と同様である。  After drilling holes 4 4 in the first mixture 18, move the mold 16, and further insert the second mixture 20 on the layer of the first mixture 18 in the mold 16 . At this time, the second mixture 20 is pushed into the holes 44 of the first mixture 18. Subsequent operations are the same as in the example through step 24.
これによれば、 第 1 の混合物 1 8の穴 4 4の壁面を規定する骨材 2 8相互間の空隙 3 2に第 2の混合物 1 4中の骨材 3 0が部分的に入 り込み、 この状態を維持したまま成形される。 その結果、 図 3に示す ように、 骨材 2 8相互の空隙 3 2 にとどめられた骨材 3 0によ り分離 を阻止された両成形層 1 2 , 1 4からなる舗装板 1 0が得られる。 工程 2 6を経るこの製造方法は、 したがって、 両混合物 1 8， 2 0 中の合成樹脂に親和性がない場合、 あるいは、 両合成樹脂がそれぞ れ熱可塑性樹脂 （例えば、 スチ レ ン、 ポ リエチ レ ン、 ポ リ プロ ピ レ ン 等） と熱硬化性樹脂とからなる場合にあっても、 両成形層 1 2 , 1 4 がー体の舗装板 1 0を得られる。 両合成樹脂が熱可塑性樹脂と熱硬化 性樹脂とからなる後者の場合、 両混合物 1 8， 2 0の加熱温度を 7 0 〜 8 0 °Cに設定することが望ましい。 これによ り、 加熱に伴う前記熱 可塑性樹脂の軟化による垂れ落ちを防止しつつ前記熱硬化性樹脂を硬 ィヒさせるこ とができる。 According to this, the aggregates 30 in the second mixture 14 partially enter the gaps 32 between the aggregates 28 defining the wall surfaces of the holes 44 of the first mixture 18. The molding is performed while maintaining this state. As a result, as shown in FIG. 3, the pavement plate 10 composed of the two molded layers 12 and 14 that were prevented from being separated by the aggregate 30 retained in the gap 32 between the aggregates 28 was formed. can get. This production method via step 26 can therefore be carried out if the synthetic resins in both mixtures 18 and 20 have no affinity, or if both synthetic resins are thermoplastic resins (eg styrene, po Even if it is made of polyethylene, polypropylene, etc.) and a thermosetting resin, it is possible to obtain a pavement board 10 in which both of the molded layers 12 and 14 are formed. In the latter case where both synthetic resins are composed of a thermoplastic resin and a thermosetting resin, it is desirable to set the heating temperature of both mixtures 18 and 20 to 70 to 80 ° C. This makes it possible to harden the thermosetting resin while preventing the thermoplastic resin from sagging due to softening due to heating.
工程 2 6を経る場合、 第 1 の混合物 1 8および第 2 の混合物 2 〇 は、 したがって、 骨材 2 8および骨材 3 0がそれぞれ互いに空隙 3 2 をおいて結合される量の合成樹脂をそれぞれ有するこ とが必要であ る。  In the case of going through step 26, the first mixture 18 and the second mixture 2〇 are therefore made of an amount of synthetic resin in which the aggregate 28 and the aggregate 30 are bonded to each other with a gap 32 therebetween. It is necessary to have each.
これに対して、 工程 2 4を経る場合、 このような制限はなく 、 骨材 相互間が樹脂液で満たされていてもよい。  On the other hand, when the process 24 is performed, there is no such limitation, and the space between the aggregates may be filled with the resin liquid.
