Weather resistance is improved and heat-insulating properties and waterproofness are maintained for a prolonged term because the heat-insulating material 3 is made up of the hot-vulcanizing silicone rubber, and the number of processes is decreased and productivity and production efficiency are enhanced because manufacture is conducted only by the operation of heating and pressing.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating profile used as a frame material, a frame material or the like of a heat insulating sash, and a manufacturing method thereof.

[0002]

2. Description of the Related Art A heat-insulating profile used for a frame material or a frame material of a heat-insulating sash and ensuring heat insulation at a boundary between an indoor and an outdoor space is generally a hollow-shaped profile. It is manufactured by filling the hollow part of the resin with a solution of synthetic resin such as hard urethane resin as a heat-insulating material and curing it, and adhering it to the inner peripheral surface of the shape as it is. Adhesiveness deteriorates due to use, and there is a risk of peeling from the adhesive surface of the profile, so conventional heat-insulating profiles lose heat insulation and waterproofness due to peeling of the heat-insulating material, and also tend to reduce rigidity and weather resistance. I am worried about strength.

Further, in a method of filling a synthetic resin in a liquid state, a resin solution is injected into a hollow portion on one side of a shape member extruded and molded as one component as in Japanese Patent Publication No. 34299/1990, and then the synthetic resin is synthesized. In order to separate the profile for the purpose of utilizing the elasticity of the resin, the manufacturing process is complicated because it requires multiple steps of cutting and inverting the connecting piece that serves as the weir plate at the time of injection and injecting it into the hollow part on the opposite side. Production efficiency is low.

The present invention has been made in consideration of the actual conditions of the conventional heat insulating profile and its manufacturing method, and it is intended to newly propose a heat insulating profile having high stability and producibility for long-term use. .

[0005]

According to the present invention, a heat-vulcanizable silicone rubber having excellent weather resistance and high stability in use is used as the heat insulating material, so that the heat insulation of the heat insulating profile can be achieved even after long-term use. Maintain heat resistance and waterproofness, and improve the manufacturability of heat-insulating profile by adhering to the profile by utilizing vulcanization of silicon rubber during heating.

Insulating material of silicone rubber is in an unvulcanized state,
It is sandwiched between a plurality of divided shape members and is adhered to both shape members by vulcanization by heating and pressurizing the shape members to form a heat insulating shape member together with the shape members.

Since the heat insulating material is silicon rubber, the weather resistance is high, and even if it is used for a long period of time, the adhered state with the shape member is maintained without peeling, and the heat insulating shape member has the heat insulating property at the time of manufacturing. And keeps waterproofness, and rigidity and strength.

In the production of the heat insulating profile, a plurality of profile members are sandwiched between them to face each other, and both profile members and the heat insulating member are heated and applied to the side where the profile members approach each other. This is performed by pressing and heat-insulating the heat-insulating material to the opposite surfaces of both the shape members to integrate the shape material and the heat-insulating material.

[0009] The production of the heat insulating profile is performed by heating the profile and the heat insulating material.
The number of steps is reduced by performing only pressurization operation,
Manufacturability and manufacturing efficiency are improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings showing an embodiment.

The heat-insulating profile 1 of the present invention is a thermal vulcanization in which a plurality of metal profiles 2 and 2 are sandwiched between the profiles 2 and 2 and vulcanized and bonded to the profiles 2 and 2. And a heat insulating material 3 made of a conductive silicone rubber, and is used as a frame material, a frame material, or the like of a heat insulating sash.

The heat insulating profile 1 is formed by combining a plurality of profile members 2 as shown in FIG. 1, which is an example of use as a frame.

As shown in FIG. 2, the shape members 2 and 2 are preliminarily divided and molded, and they are unified by adhering the heat insulating material 3. However, since the heat insulating materials 3 are separated from each other, the elasticity of the heat insulating material 3 is utilized. The two shape members 2 and 2 are relatively deformable within the range of their elasticity. The shaped members 2 and 2 may have adhesive surfaces 2 ₁ and 2 ₁ corresponding to the size of the heat insulating material 3 on opposite sides, and the cross-sectional shape thereof is arbitrary.

The heat insulating material 3 is sandwiched between the facing shape members 2 and 2, and is bonded to both adhesive surfaces 2 ₁ and 2 ₁ to be integrated with the shape members 2 and 2 to form the heat insulating shape member 1. The installation position of the heat insulating material 3 between the shape members 2 and 2 is determined according to the use part of the heat insulating shape material 1, and in the case of the frame shown in FIG. 1, the heat insulating material 3 is arranged on the outer peripheral side of the glass.

The heat insulating material 3 and the shape member 2, as will be described later,

Although is bonded to 2 _1, in the embodiment projecting from the adhesive surface 2 _1, 2 ₁ of Ryokatachizai 2,2 to supplement the adhesive hook piece 2 _2, 2 ₂ to the opposite sides, the tip By bending the bent pieces 2 ₂₁ and 2 ₂₁ into the heat insulating material 3, the integrity of the shape members 2 and 2 and the heat insulating material 3 is improved.

The heat insulating profile 1 is block-shaped heat insulator 3 on the bonding surface 2 ₁ of the previously molded one profile 2 as shown in FIG. 2
, The other shape member 2 is placed on top of it, and the heat insulating material 3 is sandwiched between them. As shown in FIG. 3, the shape members 2 and 2 and the heat insulating material 3 are heated from the outside of both shape members 2 and 2 by a hot press machine. Meanwhile, it is manufactured by applying pressure to the opposite sides of the shape members 2 and 2. The found width of the heat insulating material 3, that is, the width of the surface parallel to the bonding surface 2 ₁ of the shape member 2 is such a size as to be sandwiched between the two hook pieces 2 ₂ and 2 ₂ of each bonding surface 2 _1. heat and pressure by fluidized at the same time adhering to the adhesion surface 2 ₁ of the whole surface as shown in FIG. 4, hook piece 2 _2, 2 ₂ at the tip of the bending piece 2 _21, 2 ₂₁ bites, profile 2, Integrated with 2. At the time of heating and pressurizing the shape members 2 and ₂ , the hook surface piece of the heat insulating material 3, that is, the surface perpendicular to the adhesive surface 2 ₁ is continuous with the rising piece 2 ₂₂ of the hook piece 2 2 to be flush with each other. Weirs 4 and 4 are installed on both outer sides of the rising pieces 2 ₂₂ and 2 ₂₂ of 2 ₂ and 2 ₂ . Manufacture of the heat insulating profile 1 is substantially completed by only one step of heating and pressurizing with a hot press machine shown in FIG.

The production of the heat insulating profile 1 is performed not only in a state where each of the profile members 2 and 2 is a single body, but also in a state where each of the profile members 2 and 2 is framed in a frame shape.

FIG. 5 shows heating and heating between the profile members 2 and 2 for the purpose of improving the assembly accuracy when the heat insulating profile 1 shown in FIGS. 2 and 3 is manufactured.
This is a production example in the case where a connecting member 5 made of a hard resin having elasticity, which is capable of being compressed and deformed when being pressed, is laid across for the purpose of positioning between the two when being pressed. The connecting member 5 follows the relative deformation between the shape members 2 and 2 by its elasticity after the heat insulating shape member 1 is manufactured.

FIG. 6 shows that a heat insulating material 3 is installed at a joint portion between one of the shape members 2 and 2 which is framed in advance in a rectangular shape.
5A to 5C show an example in which waterproofing is applied to the joint portion at the same time as the production of the heat insulating profile 1 by the operation shown in FIG. In this case as well, the heat insulating material 3 is placed on the adhesive surface 2 ₁ with both hook pieces 2 ₂ ,
It is installed in the state of being sandwiched between 2 ₂ .

[0020]

As described above, the present invention uses a heat-vulcanizable silicone rubber having high weather resistance and stability as a heat insulating material,
Since it is formed by vulcanizing and adhering this to a profile,
The adhesive state between the heat insulating material and the profile can be maintained even after long-term use, and the heat insulating property, waterproof property and strength at the time of production can be maintained.

Further, since the heat insulating profile is manufactured only by the operation of heating and pressurizing, the number of steps required for manufacturing can be reduced and the manufacturability and the manufacturing efficiency can be improved.
