Description

Technical Field

[0001] The utility model belongs to the technical field of decorative materials, and relates to an enhanced sound-insulating and heat-insulating integrated wall aluminum gusset plate for indoor and outdoor wall decoration, specifically a composite aluminum gusset plate with strong impact and deformation resistance and strong sound-insulating and heat-insulating functions. Background Art

[0002] Aluminum gusset plates have good moisture-proof, oil-proof and flame-retardant properties, as well as beautiful appearance and easy use. They are widely used in home decoration and engineering decoration. Usually, aluminum gusset plates are based on aluminum alloy plates, which are obtained by cutting, cutting corners, and compression molding. Since the aluminum alloy material used to make aluminum gusset plates is thin and has low hardness, aluminum gusset plates generally have the disadvantages of being not impact-resistant and easy to deform, and do not have functions such as sound insulation and heat insulation. In order to solve the above problems, existing products are enhanced by adding reinforcing ribs, aluminum-plastic composites and honeycomb structures. For sound insulation and heat insulation, the main technology used is to add a rubber layer, but the effect is limited. At present, there is no integrated wall aluminum gusset plate that combines high strength and good sound insulation and heat insulation. Utility Model Content

[0003] The purpose of the utility model is to provide an enhanced sound insulation and heat insulation integrated wall aluminum gusset plate in view of the above problems.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An enhanced sound insulation and heat insulation integrated wall aluminum gusset plate comprises an aluminum gusset plate body, wherein a composite material layer, a polyurethane foam layer and an epoxy board layer are fixed in sequence from bottom to top at the bottom of the groove of the aluminum gusset plate body.

[0006] In the above-mentioned enhanced sound insulation and heat insulation integrated wall aluminum gusset plate, the thickness of the composite material layer is 1-5 mm.

[0007] In the above-mentioned enhanced sound insulation and heat insulation integrated wall aluminum gusset plate, the thickness of the polyurethane foam layer is 1-8 mm.

[0008] In the above-mentioned enhanced sound insulation and heat insulation integrated wall aluminum gusset plate, the thickness of the epoxy board layer is 1-3 mm.

[0009] In the above-mentioned enhanced sound insulation and heat insulation integrated wall aluminum gusset plate, the bottom and edge of the epoxy board layer are respectively glued and fixed to the polyurethane foam layer and the inner wall of the aluminum gusset plate body.

[0010] In the above-mentioned enhanced sound insulation and heat insulation integrated wall aluminum gusset plate, the composite material layer is formed by curing short glass fiber and thermosetting resin.

[0011] In the above-mentioned enhanced sound insulation and heat insulation integrated wall aluminum gusset plate, the polyurethane foam layer is formed by foaming polyurethane with a modulus greater than 10Mpa.

[0012] Compared with the existing technology, the advantages of the utility model are:

[0013] The aluminum gusset plate of the utility model integrates high strength and sound insulation and heat insulation. After the aluminum gusset plate is reinforced with composite materials, the product service life can be significantly increased. The sound insulation and heat insulation function can reduce the sound insulation and heat insulation construction of the wall during indoor and outdoor decoration, shorten the construction period, and reduce the decoration cost.

[0014] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a structural schematic diagram of the utility model.

[0016] In the figure: aluminum gusset plate body 1, composite material layer 2, polyurethane foam layer 3, epoxy board layer 4. DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0018] Example 1

[0019] like Figure 1 As shown, a mixed slurry of epoxy resin and chopped glass fibers is poured into the groove of the aluminum gusset body 1 in a pouring device, the pouring thickness is 1 mm, and a composite material layer 2 is obtained after curing and molding. 1 cm of foamed polyurethane is sprayed to obtain a polyurethane foam layer 3. During the foaming process of the foamed polyurethane, a 1 mm epoxy board with epoxy resin evenly coated on the lower surface and edge is pressed onto the polyurethane foam layer 3, and an epoxy board layer 4 is formed on the polyurethane foam layer 3, thereby forming a sandwich of the composite material layer 2, the polyurethane foam layer 3 and the epoxy board layer 4, and the sandwich is a sandwich structure. In this example, the impact strength of the integrated wall aluminum gusset is greater than 95 kJ / m 2 , thermal conductivity 0.028W / (m·K), achieving a sound insulation effect of 20 decibels.

[0020] The utility model solves the problems of aluminum gussets for wall decoration being weak in impact resistance, easy to deform, and poor in sound insulation and heat insulation. The composite material layer, polyurethane foam layer, and epoxy board layer form a closed sandwich structure, which can greatly improve the strength and sound insulation and heat insulation effect of the aluminum gussets.

[0021] Thermosetting resin filled with chopped glass fiber is poured on the back of the aluminum gusset plate, and the cured composite material forms the main reinforcement layer of the aluminum gusset plate. Thermosetting resins such as epoxy resin and phenolic resin with high bonding strength with aluminum alloy materials are used. In order to achieve high strength and high toughness of the composite material, chopped glass fiber is used as the reinforcing fiber.

[0022] The bonding process of the composite material layer and the aluminum gusset body is to pour a mixed slurry of chopped glass fiber and thermosetting resin into the groove of the aluminum gusset in a pouring device, and then place it in a curing box for curing and forming.

[0023] The foamed polyurethane placed on the composite material layer is one of the materials with the lowest thermal conductivity. The thickness of the foamed polyurethane layer is 1 cm, and the modulus of the resin is greater than 10 MPa. Accurately measured liquid foamed polyurethane resin is sprayed on the composite material layer. During the foaming process of the foamed polyurethane, an epoxy board with epoxy resin evenly coated on the surface and edges is pressed on the foamed polyurethane layer to form a closed sandwich structure after compaction. The thickness of the epoxy board in this embodiment is 1 mm.

[0024] In the present invention, the performance test standards such as impact strength of the enhanced sound insulation and heat insulation aluminum gusset plate refer to GB / T1451-2005, the sound insulation test standard refers to GB50118-2010, and the thermal conductivity test standard refers to GB / T 10294-2008.

[0025] The utility model adopts a composite structure design, sprays a sound-insulating and heat-insulating foamed polyurethane layer on a high-strength glass fiber composite material, adheres an epoxy board on the foamed layer, and the composite material, foamed polyurethane and epoxy board form a closed sandwich structure, which can greatly improve the strength and sound-insulating and heat-insulating effect of the aluminum gusset plate. The aluminum gusset plate is far superior to ordinary aluminum gusset plates in terms of impact resistance, bending resistance, sound insulation and heat insulation.

[0026] Example 2

[0027] The structure and principle of this embodiment are basically the same as those of embodiment 1, except that a mixed slurry of epoxy resin and chopped glass fibers is poured into the groove of the aluminum gusset body 1 in a pouring device with a pouring thickness of 2 mm to obtain a composite material layer 2. After preliminary curing and forming, 5 cm of foamed polyurethane is sprayed to obtain a polyurethane foam layer 3. During the foaming process of the foamed polyurethane, a 2 mm epoxy board with the surface and edge evenly coated with epoxy resin is pressed onto the polyurethane foam layer 3 to form an epoxy board layer 4, forming a sandwich structure. The impact strength of the integrated wall aluminum gusset in this example is greater than 190 kJ / m 2 , thermal conductivity 0.025W / (m·K), achieving a sound insulation effect of 26 decibels.

[0028] Example 3

[0029] The structure and principle of this embodiment are basically the same as those of embodiment 1, except that a mixed slurry of epoxy resin and chopped glass fiber is poured into the groove of the aluminum gusset body 1 in a pouring device with a pouring thickness of 5 mm to obtain a composite material layer 2. After preliminary curing and forming, 8 cm of foamed polyurethane is sprayed to obtain a polyurethane foam layer 3. During the foaming process of the foamed polyurethane, a 3 mm epoxy board 4 with epoxy resin evenly coated on the lower surface and edge is pressed onto the polyurethane foam layer 3 to form a sandwich structure. The impact strength of the integrated wall aluminum gusset in this example is greater than 270 kJ / m 2 , thermal conductivity 0.022W / (m·K), achieving a sound insulation effect of 30 decibels.

[0030] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways without departing from the spirit of the present invention.
