Abstract

PURPOSE: To obtain a resin panel enhanced in heat resistance, durability, and chemical resistance to a great extent and improved in novelty of surface design and weatherability by mixing a resol phenol resin powder in a hard substrate made of a synthetic resin. CONSTITUTION: A hard substrate 2 is formed by loading and mixing resol phenol resin powder 4 in a synthetic resin 3. The synthetic resin is made of one or more of a vinyl chloride resin, an acrylic resin, a polyester resin, a polyurethane resin, a phenol resin, an alkyd resin, a polycarbonate resin, and the like. The use of the resol phenol resin powder 4 enhances the heat resistance, mechanical strength, and weatherability of the synthetic resin insufficient in heat resistance and compression strength, upgrades an appearance of a decorative surface, and improves a flowability at the time of molding the synthetic resin. In a resin panel of a sandwich structure, a plastic foam is integrally provided as a backing material on the rear surface of the hard substrate 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interior / exterior material for buildings and structures, particularly to a resin panel most suitable for remodeling.

[0002]

2. Description of the Related Art In general, ceramic-based and metal-based dry construction methods have become mainstream as interior and exterior materials. In particular, expensive aluminum, stainless steel, titanium alloys, etc. are used for special environments such as reforms and coastal areas.

[0003]

However, the ceramic system has the disadvantages of being heavy and poor in workability, and lacking in waterproofness and durability of the coating film. Further, metal systems, especially surface-treated steel sheets, have a problem in corrosion resistance such as rust or chemical resistance. Therefore, it is necessary to coat with a special coating film having good anticorrosion property.

[0004]

In order to eliminate such drawbacks, the present invention mixes a resol-type phenol resin powder in a synthetic resin hard base material to significantly improve heat resistance, durability and chemical resistance. We propose a resin panel with various reinforcements and novelty of surface design and improvement of weather resistance, and a resin panel of composite structure in which plastic foam is integrally fixed to this hard base material, or a resin panel of sandwich structure. .

[0005]

EXAMPLE An example of the resin panel according to the present invention will be described in detail below with reference to the drawings. 1 and 3
Is a perspective view and a cross-sectional view showing a typical example of a resin panel according to the present invention. Reference numeral 1 is a resin panel for molding a hard base material 2 into a box type, or a cross-section as shown in FIGS. 3 and 4. It is formed in a long shape, and is fixed to a skeleton or the like through a through hole 6 of the mounting edge 5 through a fixture or an adhesive A as shown in FIG.

To further explain, the hard base material 2 is a synthetic resin 3 (plastic material) to which a resol type phenol resin powder 4 is added and mixed, as shown in a partially enlarged view in FIG. The synthetic resin 3 is made of one or more of vinyl chloride resin, acrylic resin, polyester resin, polyurethane resin, phenol resin, alkyd resin, polycarbonate, and the like.

The resol type phenol resin powder 4 is, for example, spherical and has a size of about 0.05 to 10 mm and a bulk density of 0.065 to 0.8 g / cm ³ , (a) heat melting type, (b) ) There are four types such as partial heat melting type, (c) heat non-melting type, or (d) firing type,
Especially in the case of a true sphere, the fluidity is good. The purpose of using this resol type phenol resin powder 4 is to improve the heat resistance of synthetic resin (plastic) lacking heat resistance, improve the mechanical strength of synthetic resin (plastic) lacking compressive strength, improve weather resistance, and improve the appearance of the decorative surface. This is for strengthening and improving the fluidity during molding of synthetic resin. The addition amount varies depending on the purpose, but is 10 to 200 parts by weight relative to 100 parts by weight of the raw material of the synthetic resin 3, for example.

FIG. 3 shows a resin panel 1 having a composite or sandwich structure, which is another invention of the resin panel according to the present invention, in which a plastic foam is integrally formed as a backing material 7 on the back surface of the hard base material 2. The plastic foam is polyurethane foam, polyisocyanurate foam, phenol foam, polyethylene foam, etc. Depending on the purpose, gypsum board, ALC board, sheathing board, etc. may be used.

Further, in the sandwich structure, as the backing material 8, kraft paper, aluminum foil, aluminum kraft paper,
Non-woven fabric (made of carbon, alumina, rockwool, graphite, inorganic fibers such as glass, polyester-based, nylon-based, aramid-based resin), asphalt felt, or thin metal plate such as iron, aluminum, if necessary.
Copper, stainless steel, titanium, aluminum / zinc alloy plated steel plate, enamel steel plate, clad steel plate, laminated steel plate (PVC steel plate, etc.), sandwich steel plate (vibration control steel plate, etc.) (of course, colored metal plates coated in various colors) Including)
One of the above is molded into various shapes by roll molding, press molding, extrusion molding or the like, or is made of an inorganic material.

Next, in order to evaluate the heat resistance of the resin panel according to the present invention, 100 parts by weight of the molten vinyl chloride resin was mixed with 4 parts of the resol type phenol resin powder 4 (average particle size 0.0
5 mmφ) is added in an amount of 80 parts by weight, and a hard substrate 2 having a thickness of 3 mm is extruded from an extruder (not shown) (flat or various shapes are extruded, and in the case of flat, roll molding is performed), and then cooled resin Panel 1. Further, a hard base material 2 having the above composition is extruded into a shape shown in FIG. 3, and a resol type phenol foam (density 40 kg / m ³ ) is laminated as a backing material 7 to form a backing material 8.
It is assumed that the sandwich-shaped resin panel 1 is manufactured by using aluminum kraft paper. The thickness T is 25
mm, width W was 250 mm.

Therefore, J is applied to the above two resin panels 1.
When the quasi-nonflammability test according to IS-A-1321 was conducted,
All of them passed the test, and the smoke emission coefficient and the calorific value of the panel formed of the vinyl chloride resin alone exceeded the pass values immediately after the start of the test and failed.

The above description is only one embodiment of the resin panel according to the present invention, the hard base material 2 can be extruded as shown in FIG. 4, and the male type connecting portion 9 and the female type connecting portion 10 can be extruded. And the grid 11 is provided on the resin panel 1.

5 to 7 show a male connecting portion 9 and a female connecting portion 1.
It is a modified example of No. 0, and is a resin panel 1 in which a protrusion 12 (hard or soft) and a soft fin 13 are waterproof and a single layer or more is planted for preventing play at the time of connection. Further, FIG. 8 shows the resin panel 1 in which the cosmetic ridges 14 are provided on the surface of the resin panel 1. Further, FIG. 9 may be a resin panel 1 in which a film 15 such as a fluorine film, a vinyl chloride resin, a colored film, or a metal foil is integrally bonded on a hard base material 2, particularly when it is extrusion molded. In addition, in terms of shape, FIG.
It is also possible to form the cross sections as shown in (a) to (c) to FIGS. 19 (a) to (e). It should be noted that FIG.
(E) and FIGS. 19 (a) to (e) show a resin panel 1 extruded into a flat plate shape and then formed into various shapes by roll forming or the like.

[0014]

As described above, according to the resin panel of the present invention, a synthetic resin extruded material lacking fire resistance and a roll molding material can be made into a resin panel having a performance higher than that of a semi-incombustible material. The resol type phenolic resin powder, which is an aggregate and also has fire resistance, can be easily mixed with various synthetic resins and has a novel compressive strength and appearance.
The weather resistance can be improved. The waterproof projections and the soft fins are extremely effective for connecting parts of this type of panel with high dimensional accuracy. The soft fin serves as play at the connecting portion, which facilitates construction and improves waterproofness. Weight reduction can be achieved.
There are characteristics and effects.
