DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a laminate in which a thermoplastic resin molded article is reinforced with a polymerizable curable resin.

[0002]

2. Description of the Related Art In a thermoplastic resin molded product, the thermoplastic resin constituting the molded product is used as a surface layer, and the back surface is reinforced with a fiber-reinforced polymerization curable resin (hereinafter, referred to as FRP) to increase the strength of the molded product. Various improved products are on the market. For example, in a bathtub or a sink, an acrylic resin having an excellent appearance is used for a surface layer instead of a gel coat layer, and the back surface is reinforced by FRP.

As described above, the reason why a thermoplastic resin molded product requires reinforcement is that a thermoplastic resin plate can be easily given various shapes by vacuum forming, pressure forming, press forming, etc. The molded product has a reduced thickness in a deep drawing shape, and as it is, the shape is not maintained and the strength during use is insufficient. Because it is a thermoplastic resin, its use at high temperatures is limited. For that reason.

[0004] FRP is usually laminated by a hand lay-up method or a spray-up method. In this method, bubbles are easily entrained at the time of lamination, and thus the defoaming operation of the FRP is performed. Therefore, it is difficult to confirm the presence of air bubbles from both the thermoplastic resin side and the FRP side, so skill was required, and it was difficult to completely remove the air bubbles.

[0005] The presence of air bubbles in an FRP product is liable to be broken when an impact is applied thereto, as compared with a portion that is in close contact with the product. In the case of a bathtub or the like, it is exposed to hot water or used for a long period of time with a temperature change. This causes problems such as cracks and the like.

[0006] In addition, the operation of laminating FRP by the hand-array-up method or the spray-up method may impair the working environment, such as using a reactive resin containing a highly toxic solvent or scattering glass fibers.

In recent years, there has been no need to perform defoaming work.
As a method that does not impair the working environment, use a thermoplastic resin molded product in one of the molds, combine it with the other mold to form a cell, inject the polymerization curable resin raw material, polymerize and cure, and form a thermoplastic resin molded product A method of integration is disclosed and proposed in JP-A-51-91965, JP-A-5-237854 and the like.

[0008]

However, in these methods, when the thermoplastic resin molded article used as one of the molds is filled with a polymer curable resin material, the molded article is easily formed by the pressure of the polymer curable resin material and its own weight. It may be deformed.

For example, an acrylic resin plate is formed into a bathtub shape by a vacuum forming method, and the bottom surface of the formed product has a width of about 40 mm.
When the thickness is 0 mm and the length is about 800 mm, and the thickness is distributed from 1 mm to 2 mm, the pressure applied to the outer surface of the molded product is only 0.01 kg / cm ² and the center of the bottom is about 2.5 m.
m. This means that the molded article undergoes large deformation when the polymerization curable resin material is injected and filled, and it is difficult to achieve the target thickness of the laminated material. As described above, the thermoplastic resin molded article has various problems such as not only being required as a surface layer material but also requiring a sufficient thickness in terms of strength. Further, when glass fiber or the like is present, the flow of the polymer-curable resin material is hindered, so that it is difficult to quickly fill the cell with the polymer-curable resin material.

The present invention has been made to solve such a problem. That is, according to the present invention, it is possible to obtain a laminate having a desired lamination thickness by maintaining the shape of the cell outer surface on the mold side made of the easily deformable thermoplastic resin molded product by various pressing means.

[0011]

According to the present invention, a cell is formed by combining one easily deformable mold composed of a container-shaped thermoplastic resin molded article and a mold that is not substantially deformed. While maintaining the shape by pressurizing the outer surface of the cell on the mold side composed of the product, the polymer curable resin material is poured into the cell to fill it, and then the polymer curable resin material is polymerized and cured, and is integrated with the thermoplastic resin molded product. And forming the laminate into a laminate, and then releasing the laminate from the mold that is not substantially deformed.

Further, according to the present invention, in the above-mentioned invention, the distance between the two molds is made variable, and the polymerization-curable resin raw material is injected with the distance between the two molds being larger than the thickness of the laminated material intended. While pressing the outer surface of the cell on the mold side made of the thermoplastic resin molded article, the distance between both molds is reduced to a predetermined distance to fill the cell with the polymer curable resin material, and then polymerize the polymer curable resin material. A method for producing a laminate, characterized in that after being cured and integrated with the thermoplastic resin molded article to form a laminate, the laminate is released from the substantially non-deformable mold.

Further, according to the present invention, a polymer-curable resin raw material is placed on a substantially invariant mold having a similar shape to a container-shaped thermoplastic resin molded product, and then the container-shaped thermoplastic resin is placed on the mold. The cell is formed by setting the resin molded product as the other easily deformable mold, or the cells are formed at intervals larger than the thickness of the intended laminated material, or from the thermoplastic resin molded product while forming Filling the cell with the polymer curable resin material by pressing the outer surface of the cell on the mold side to narrow the distance between the two molds to a predetermined distance, then polymerizing and curing the polymer curable resin material, and then forming the thermoplastic resin molded article And then releasing the laminate from the substantially non-deformable mold.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A container-shaped thermoplastic resin molded article usable in the present invention is obtained by thermoforming a thermoplastic resin plate. As the thermoplastic resin plate, an acrylic resin plate, a polystyrene plate, an ABS resin plate or a laminate thereof,
A thermoformable resin plate such as vacuum forming, pressure forming or press forming can be used. Auxiliary molding using a plug or the like can be performed for vacuum or compressed air molding.

The thickness of these resin plates is not particularly limited, but if the thickness is too thin, cracks may occur due to the solvent contained in the reinforcing raw material resin, or heat may be generated during curing of the polymerizable resin material. Due to the deformation, 0.3 mm or more where the thickness of the molded product is the thinnest, further 0.8 mm
It is preferable to make the above. In addition, printing on these resin plates and laminating films are not prevented.

An acrylic resin plate particularly excellent in thermoforming processability and solvent resistance is disclosed in Japanese Patent Publication No. 6-70098, methyl methacrylate alone or 60% by weight or more of methyl methacrylate and acrylic ester 40.
In preparing an acrylic resin plate by polymerizing a monomer mixture of not more than 1% by weight in the presence of a polymerization initiator, 0.01 to 20% by weight of a chain transfer agent is added to the entire monomer in advance. It is preferable to use an acrylic resin plate obtained by preparing a syrup by adding 0.02 to 1.0% by weight of a crosslinking agent to the obtained syrup and casting-polymerizing in a mold.

As the polymerizable curable resin of the reinforcing layer for reinforcing the thermoplastic resin molded product, unsaturated polyester resin, acrylic resin, vinyl ester resin, urethane resin, epoxy resin, and resins modified from these can be used.
Including foamed resin. Examples of the unsaturated polyester resin include iso-, tele- or bis-unsaturated polyester resins and their acryl-modified unsaturated polyester resins or unsaturated resins obtained by adding an acrylic resin to the iso-, tele- or bis-unsaturated polyester resins. It is selected from at least one of polyester resins.

It is to be noted that these polymerizable and curable resins have an affinity for a thermoplastic resin molded article in the form of a container, and those which can be polymerized and cured and can be tightly integrated with the thermoplastic resin molded article are used. It is appropriately selected according to the type of resin of the molded article.

In the present invention, a filler for reinforcement can be mixed with the polymer curable resin which is filled by being injected or charged into the cell, and specific examples thereof include aluminum hydroxide, calcium carbonate, and glass fiber. Known fillers such as carbon fiber, aramid fiber and polyester fiber can be used. These can be used alone or in appropriate combination of two or more kinds. These fillers are preferably subjected to a coupling treatment.

When glass fiber is used, the glass fiber preform is formed into a glass fiber preform by matting it into a woven or nonwoven fabric, or by spraying or pressing it into a shape substantially the same as a container-shaped thermoplastic resin molded product. You can also keep
These can be set in a cell prior to injecting or charging the polymerizable resin material. Fillers, glass fiber mats and glass fiber preforms are mainly mixed in to improve the strength and to improve the heat resistance, and the content is from 10% by weight based on the polymerizable curable resin material to be filled. It is preferable to use it in the range of 90% by weight.

Further, a veneer plate or a resin plate divided into one or a plurality of pieces as a reinforcing material is inserted between one easily deformable mold made of a thermoplastic resin molded article and a substantially non-deformable mold to be polymerized and curable. It is also effective to integrate with resin. The thickness of the reinforcing layer is adjusted by the size of the space (cell spacing) between one easily deformable mold made of the thermoplastic resin molded product on the surface layer and the mold that does not substantially deform.

When polymerizing and curing the polymer-curable resin raw material filled in the cell, it is necessary to control the curing conditions so that the heat generated by curing does not deform the container-shaped thermoplastic resin molded product. Specifically, the heat generation temperature is prevented from increasing by reducing the amount of the curing agent. Further, it is also effective to degas the polymerizable curable resin material to be filled so that the polymerizable curable resin material does not foam during curing.

As shown in the drawing, the cell is composed of one mold, a container-shaped thermoplastic resin molded article 1 and a mold 2 which is not substantially deformed. The substantially non-deformable mold 2 refers to a mold having a high deformation strength and a rigid structure that does not substantially deform.

Types of the mold 2 include an FRP mold using an epoxy resin, a vinyl ester resin, an unsaturated polyester resin, etc., a mold composed of a laminate of FRP and resin concrete, and a Ni electroforming mold (FRP mold). Surface-coated with nickel), metal molds such as aluminum, and those reinforced with a rib structure. After the polymerization-curable resin material filled in the cell is polymerized and cured, it is released from the mold 2 which is not substantially deformed. Therefore, a surface of the mold 2 in contact with the polymer-curable resin material is coated with a release agent,
Alternatively, it is preferable to perform lamination with a non-contact material such as Teflon.

The laminated material in the present invention means a polymer-curable resin layer composed of a polymer-curable resin material alone, and a polymer-cured resin layer composed of a polymer-curable resin material containing a glass fiber mat or a glass fiber preform.

When pouring a polymer curable resin material into the cell, the mold 2 is provided with a polymer curable resin material inlet 5.
In addition, in the case where the polymerizable curable resin raw material is charged, the injection port is not particularly provided, and the polymerizable curable resin raw material is poured into the mold 2 which is not substantially deformed in a state where the cell is opened in advance, and the thermoplastic resin molded article is further poured thereon. A method of setting as a mold is adopted. The mold 2 that is not substantially deformed has a shape substantially similar to the other thermoplastic resin molded article having a container shape.

The elimination of air in the cell during the process of filling the polymerization-curable resin raw material is achieved by a method of providing an exhaust port as shown by reference numeral 6 in the drawing and a method of forming a thermoplastic resin molded product substantially. There is a method in which air is exhausted from the outer peripheral portion of the cell in which a mold that does not deform is combined, and any method can be adopted.

When the cell is filled with the polymer-curable resin material, the outer surface of the cell is pressurized so that the mold made of the container-shaped thermoplastic resin molded product is not deformed by the injected or charged polymer-curable resin material.

In the case of a solid, the outer surface of a cell made of a thermoplastic resin molded product is formed by a presser or the like, which is divided as indicated by reference numeral 10 in FIG. And pressurize. The presser to be pressed is made of FRP such as epoxy resin, vinyl ester resin and unsaturated polyester resin, metal such as aluminum, wood, and the like. The temperature control of the fluid or solid pressurized body is also effective for the moldability such as the molding cycle up similarly to the mold temperature control.

In the present invention, when the cell outer surface of the easily deformable mold side made of a container-shaped thermoplastic resin molded article is pressurized, when the shape and dimensions of the mold made of the thermoplastic resin molded article are changed, it is added by a fluid. Although the pressure is not particularly problematic, the pressurization by a solid may cause a problem in fitting. In this case, except for the corners, etc., which are not easily deformed, by pressing the easily deformable portions such as the flat portions with the presser, the shape margin of the mold and the presser made of the thermoplastic resin molded product and the shape of the obtained laminate are obtained. Stability can be improved.

Further, the outer surface of the cell is divided by a holding member which is divided.
If you RiKa圧, it is adhered by the, for example, a reduced pressure state between the pressing surface and the mold side of the cell outer surface of a thermoplastic resin molded article of the retainer, to correct the deflection of the surface of the thermoplastic resin molded article Can be. Specifically, as shown in FIG. 6 , a depressurizing hole is provided in the presser, and degassing and depressurizing are performed therefrom. Figure
In FIG. 6 , reference numeral 13 denotes a pipe connected to a pressure reducing hole provided in the holding member so that the pipe can be connected to a pressure reducing device (not shown).

Further, in the present invention, in order to enlarge the flow cross-sectional area of the polymer-curable resin raw material, a thermoplastic resin molded article which is one of the easily deformable molds is combined with the other mold which is not substantially deformed. In forming the cell, the distance between the two molds was made variable, and the gap between the mold made of a thermoplastic resin molded article and the mold that was not substantially deformed was set to be larger than the thickness of the intended laminated material, and then polymerized and cured. Injecting or injecting a thermoplastic resin raw material, pressurizing the outer surface of the cell of the mold made of the thermoplastic resin molded article, thereby narrowing the distance between the mold made of the thermoplastic resin molded article and the mold that is not substantially deformed, and the injected polymerization The curable resin raw material is filled with the polymer curable resin raw material in the cell 9
To quickly fill the entire cell.
Next, after the polymerization-curable resin raw material is polymerized and cured to be integrated with the thermoplastic molded article to form a laminate, the laminate is obtained by releasing the laminate from the mold that is not substantially deformed.

Further, the present invention provides a method of introducing a polymerizable curable resin material into a substantially non-deformable mold substantially similar to a container-shaped thermoplastic resin molded article, and placing the container-shaped thermoplastic resin on the mold. The molded article is used as the other mold to form cells at intervals larger than the thickness of the intended laminated material, or to form both cells by pressing the outer surface of the mold side of the thermoplastic resin molded article while forming the cells. The interval between the molds is reduced to a predetermined interval, the cell is filled with the polymer curable resin material, and then the polymer curable resin material is polymerized and cured to be integrated with the thermoplastic resin molded article to form a laminate. The laminate can be obtained by releasing the laminate from the mold that does not deform substantially.

The outer periphery of the cell formed by the easily deformable mold made of a thermoplastic resin molded article and the other mold that is not substantially deformed has a seal packing 4, a clamp 3, etc. as shown in each figure. Can be sealed.

The present invention can be used for producing a bathtub, a washbasin and the like. Further, it can be preferably applied when a thin thermoplastic resin molded product is used as one of the molds.
