Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface finishing material for a heating heater provided on a surface side of a heating heater used for floor heating and wall heating.

[0002]

2. Description of the Related Art With regard to surface finishing materials for floor heating and wall heating, for example, in the case of floor heating, a laminated finishing material in which a thin decorative material is stuck on the surface of plywood or the like, so-called flooring, or
Corks, tatami mats, PVC sheets, PVC tiles, and carpets are widely used, but flooring has been rapidly increasing in recent years from the viewpoint of preventing the occurrence of mites and preventing environmental pollution at the time of disposal.

[0003]

When flooring is used as a surface finishing material for floor heating and wall heating, the flooring often comes into contact with an object in use, and therefore, the surface of the finishing material is damaged (especially dents). There was a drawback that the appearance deteriorated.
In particular, when the decorative material is a veneer, paper, or the like, it is impossible to prevent the surface from being broken due to dents. In addition, the standard thickness of the finishing material is as large as 12 mm, and since the material itself has heat insulating properties, the time required from when a heat source is turned on until the set temperature is reached, that is, the so-called rise time is delayed, and energy during operation is reduced. Loss was a major factor.

[0004] Therefore, the present invention is to provide a finish material that is resistant to scratches and has excellent scratch resistance even if the decorative material is a thin plate or a soft material, and that the thickness of the finish material is reduced to increase the heating start-up time. It is an object of the present invention to provide a surface finishing material that saves energy and saves energy at low cost.

[0005]

In order to achieve the above-mentioned object, the present invention relates to a heating heater surface finishing material provided on the front side of a panel-type heating heater. A resin-permeable sheet material containing glass fibers is superposed, and the resin is impregnated and solidified in all or a part of the sheet material and the decorative material.

[0006]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

In the embodiment shown in FIG. 1, a permeable sheet material 2 containing glass fiber is superimposed on the back surface of a permeable material 1, and resin is applied to all or a part of the sheet material 2 and the decorative material 1. Shows the surface finish 10 impregnated and solidified. The surface finishing material 10 is provided on the panel-type heating heater 3. As the decorative material 1, a veneer such as a veneer veneer (thickness of about 0.3 mm to 1.0 mm) or paper can be suitably used. A material obtained by printing wood grain on paper and performing unevenness processing along the wood grain has a texture and can be suitably used as the decorative material 1. The glass fiber forming the sheet material 2 may be a woven fabric, a nonwoven fabric, or a net-like glass fiber. In particular, regarding the nonwoven fabric, a fiber cut into 3 to 50 mm as a fiber raw material is prepared by wet papermaking or dry nonwoven fabric production. In this case, those formed into sheet materials and bonded with a binder resin can be suitably used. For short fibers with a glass fiber length of less than 3 mm,
On the other hand, with a long fiber exceeding 50 mm, it is difficult to form a uniform sheet, and as a result, an excellent reinforcing effect cannot be obtained. In addition, short fibers of 3 to 15 mm account for 2% of all fibers.
It is preferable that it is 0 to 100% from the viewpoint of strength (reinforcing property) and uniformity of the nonwoven fabric. If the short fibers are less than 20%, uniformity of the nonwoven fabric cannot be achieved. Mixing short fiber cellulose pulp or the like in addition to these fiber materials may be used. When glass fibers are used, the reinforcing effect can be enhanced by coating the fiber surfaces with a silane coupling agent. The nonwoven fabric containing glass fibers is formed into a sheet by a method of mechanically, chemically, thermally or using a solvent by bonding and / or entanglement of raw fibers, or a combination thereof. Further, from the viewpoint of impregnation, defoaming, sheet base strength, handling, and scratch resistance of the molded product, the basis weight is 50 to 2
00 g / m ² is desirable. Glass nonwoven fabric has a basis weight of 50
When the amount is less than g / m ² , scratch resistance is hardly developed and 200
If the amount is more than g / m ² , it becomes difficult to impregnate the resin. Examples of the resin which is impregnated into the decorative material 1 and the sheet material 2 and solidified are, for example, a phenol resin obtained by a reaction between a phenol and an aldehyde, and a curing agent for an oligomer having a reactive epoxy group at a terminal. Examples thereof include an epoxy resin, a urea resin, and a urethane resin obtained by addition, and further include various fillers such as lead stearate, dibutyltin dilaurate, carbon black, calcium carbonate, titanium white, mica, glass spheres, and hydroxide. Aluminum, antimony oxide, tri (2,3 dibromopropyl) phosphate, fatty acid sulfonates, higher alcohol sulfates, etc., heat stabilizers, reinforcing agents, flame retardants, antistatic agents and the like are used in combination. When a phenol resin is selected as the thermosetting resin, alkylamine, ammonia, sodium hydroxide, barium hydroxide, and the like are preferable as a catalyst required for producing the resin. In particular, alkylamine and ammonia have larger molecular weights than the other two, and have low hydration properties in terms of molecular structure, so that the water resistance after bonding is remarkably improved. At this time, the phenol resin is dissolved in water or alcohol (in the case of alcohol, the boiling point is low and it is easy to dry) so that the solid content becomes 20 to 80%.
OH is preferred) in terms of ease of impregnation. If the solid content is less than 20%, it becomes difficult to impregnate the required amount, and if it is more than 80%, the impregnation becomes difficult due to an increase in viscosity. The resin to be impregnated into the glass fibers contains at least 50% by weight of the fiber (weight ratio), and preferably 100 to 300%. When impregnating the sheet material 2, the solid content is 50 to 500 g /
m ² , preferably 150 to 350 g / m ² . If it is less than 50 g / m ^2, it is difficult to develop sufficient scratch resistance, and if it is less than 500 g / m ² , it takes a long time to cure and there is a problem in appearance such as protruding from an end.

After the glass fiber is impregnated with the resin solution as described above, the resin is dried under a certain condition to bring the resin into a semi-cured state. That is, the prepreg is formed. Prepreg is a fiber reinforced material and thermosetting resin, other thermoplastic resin as needed,
It is a molding material in a semi-cured state before the completion of curing, which retains adhesiveness and moldability of a reinforced plastic obtained by mixing a coloring agent, a curing catalyst, etc., and has a preferable gel time of 150 ° C.
30 to 800 seconds.

The thermosetting resin impregnated in the glass fiber is
As the drying conditions for setting the cured state in the latter half of the impregnation, the solvent content in the prepreg state is 3 to 15% by weight, more preferably 5 to 15% by weight.
The content is preferably set to 10% by weight, and if it is less than 3% by weight, poor adhesion to the decorative material 1 occurs, and if it is not less than 15% by weight, prepreg blocking occurs. 90-1
A preferable semi-cured prepreg can be obtained at a temperature of 20 ° C. and a drying time of 2.5 to 20 minutes.

[0010] The tensile strength of the prepreg is preferably 10 kgf / cm ² or more in order to sufficiently develop scratch resistance. If it is less than 10 kgf / cm ² , sufficient scratch resistance will not be exhibited. The measurement of the breaking strength is as follows. The prepreg is sandwiched between two release papers, 150 ° C., 5 minutes, 10 kg
The test was performed after the resin was cured by hot pressing under the condition of f / cm ² .

As described above, when the prepreg in which the glass fiber is impregnated with the thermosetting resin in a semi-cured state is superimposed on the back surface of the decorative material 1 and hot pressed, the condition is a temperature of 130 ° C. to 180 ° C. Preferably, furthermore 140-1
60 ° C. is preferred. If the temperature is lower than 130 ° C., the curing of the resin is not sufficient. If the temperature is higher than 180 ° C., the curing of the resin is too fast and the contact with the decorative material 1 becomes insufficient. This is because the warpage increases. As the pressure is preferably 1~30kgf / cm ^2, of 1 kgf / cm lower than ² and resin decorative material 1
Adhesion decreases due to insufficient bleeding
If it is larger than kgf / cm ² , inconveniences such as an increase in warpage of the decorative material 1 occur. Further, the pressing time is preferably 2.5 to 20 minutes, more preferably 3 to 20 minutes.
~ 12.5 minutes. If the time is shorter than 2.5 minutes, the curing of the resin is not sufficient, and if the time is longer than 20 minutes, the resin is deteriorated and the warp of the decorative material 1 is increased.

A woven or non-woven fabric containing glass fibers is used alone, and a material impregnated with a semi-cured thermosetting resin (prepreg) is not used alone. A material obtained by laminating the prepreg on a material impregnated with a curable resin can also be used. For example, if the uncured phenol resin is impregnated into paper and the prepreg is bonded to the paper, the overall strength and dimensional stability are dramatically improved.

FIG. 1 shows a sheet material 2 on which a sheet material 2 is superimposed and fixed on the back surface of a decorative material 1, and FIG. 2 shows a sheet obtained by bonding a metal plate 4 to the sheet material shown in FIG. For example, a glass nonwoven fabric is used as the sheet material 2, and a solid content of 50 to 500 g /
impregnated with a phenol resin solution so as to obtain m ^2, and after the impregnation, dried at a predetermined temperature and time to make the phenol resin in a semi-cured state (prepreg state), and the phenol resin impregnated in the glass nonwoven fabric is in a semi-cured state. Sometimes, a material that is superimposed on the cosmetic material 1 can be used. In the surface finishing material 10 shown in FIG. 1, the resin is impregnated into the decorative material 1 by hot pressing after the glass nonwoven fabric in which the resin is in a semi-cured state is overlaid on the back surface of the decorative material 1. In the surface finishing material 10 shown in FIG. 2, the metal plate 4 is bonded to the back surface of the sheet material 2 after the decorative material 1 and the sheet material 2 are fixed. The thickness of the surface finishing material 10 can be 1 mm or less, and preferably 3 mm or less at most. By setting the thickness to 3 mm or less, the rise time of heating can be shortened. Surface finishing material 1
Even if the thickness of 0 is reduced, the use of the prepreg provides excellent strength and scratch resistance. In addition, by reducing the thickness, the temperature of the heat source during operation can be lowered, and energy saving can be achieved.

In the surface finishing material 10 shown in FIG. 1, the content of resin such as phenol resin is 30% by weight or more.
Preferably it is 60 to 150% by weight.

A veneer veneer having a thickness of 0.3 mm is used as the decorative material 1 and a nonwoven fabric having a basis weight of 100 g / m ² made of glass fiber having a fiber length of 3 mm is used as the sheet material 2. The glass nonwoven fabric is impregnated with a phenolic resin so that the resin content in the sheet material 2 becomes 30% by weight, the prepreg is formed under a certain condition, and the resin is impregnated on the back surface of the decorative material 1 in the prepreg state. Example 1 was obtained by laminating nonwoven fabrics and then hot pressing to fix the decorative material 1 and the sheet material 2 together. In addition, the glass fiber length was 12 mm, and the other conditions were the same as those of Example 1 to manufacture Example 2. Example 3 was manufactured in the same manner as in Example 1 except that the content of the phenol resin was 100% by weight. A glass fiber length of 12 mm, a resin content of 100% by weight, and the other conditions were exactly the same as those of Example 1, and were manufactured as Example 4. Example 5 was manufactured in the same manner as in Example 4 except that the resin content was 150% by weight. Further, Comparative Example 1 was obtained by directly bonding the decorative material 1 (0.3 mm thick veneer veneer) directly to the base material 5 (12 mm thick plywood) with a urea-melamine adhesive (see FIG. 3). ).

In Examples 1 to 5 and Comparative Example, J
A pencil scratch test was performed based on IS K-5400. The results were as shown in Table 1 below. In the pencil scratch value, “H” was evaluated as “X”, “2H” as “Δ”, “3H” as “○”, and “4H or more” as “◎”.
The evaluation becomes worse in the order of ◎, ○, Δ, ×.
