Description

Technical Field

[0001] The present invention relates to the technical field of plastic sound insulation boards, in particular to a plastic sound insulation board that can be installed and shaped on site and a manufacturing process thereof. Background Art

[0002] Plastics are playing an increasingly important role in human society and everyday life. However, excessive plastic use not only leads to increasingly serious environmental pollution but also results in significant resource waste. In this context, utilizing waste plastics through modification to create low-cost sound-absorbing materials can help reduce costs for construction companies.

[0003] Plastic sound insulation panels are widely used in aircraft cabins, ship cabins, and other areas. However, existing traditional plastic sound insulation panels are shaped and delivered to the user for installation. This poorly matches the structural surface they are installed on, and they cannot be processed and re-used. Furthermore, shaped sound insulation panels are far less convenient to transport than straight panels. Therefore, to address these issues, a plastic sound insulation panel that can be shaped and installed on-site and a manufacturing process are proposed. Summary of the Invention

[0008] Preferably, one side surface of the plastic sound insulation board body is bonded and covered with an adhesive layer.

[0009] Preferably, a tear film is provided on the outer surface of the adhesive layer.

[0010] A manufacturing process for a plastic sound insulation board that can be installed and shaped on site is characterized by the following specific process steps: Step 1: Using two injection molds, a plastic sound insulation board body with a sound-absorbing hole block distribution and a plastic base plate with a circular hole distribution are respectively processed; Step 2: One end of the spiral electric heating wire is fixedly connected to the inside of each circular hole on the plastic substrate, and the spiral portion of the spiral electric heating wire contacts the other side surface of the plastic substrate; Step 3: Partially remove the injection mold used for the plastic sound insulation board body to expose the other side surface of the plastic sound insulation board body, and pre-fix the other side surface of the plastic substrate that contacts the spiral portion of the spiral electric heating wire to the other side surface of the plastic sound insulation board body in an orderly manner; Step 4: Use ultrasonic welding to weld the plastic substrate and the plastic sound insulation board body together; Step 5: First, fill the space between the sound insulation blocks with sound insulation cotton, and then provide an adhesive layer on one side of the plastic sound insulation board body; Step 6: Mark the ends of a group of spiral electric heating wires distributed in different locations on one side of the plastic substrate in different colors according to the distribution of the lines of the user's product appearance; Step 7: Configure the installation instructions and pack for shipment.

[0018] See also Figure 1-5 As shown, a plastic sound insulation board that can be installed on site includes a plastic sound insulation board body 1 and a plastic substrate 2. A plurality of sound-absorbing hole blocks 110 are integrally distributed on one side surface of the plastic sound insulation board body 1. A plurality of circular holes 210 are distributed on the surface of the plastic substrate 2, and one end of a spiral electric heating wire 6 is inserted into each circular hole 210. The spiral electric heating wire 6 is located between the plastic substrate 2 and the plastic sound insulation board body 1. The effective range of the spiral electric heating wire 6 is the cross portion where the plurality of sound-absorbing hole blocks 110 are spaced apart and intersected. The ends of the plurality of spiral electric heating wires 6 located on one side surface of the plastic substrate 2 are not limited to being electrically connected in series at one location.

[0019] like Figure 1 As shown, each interval formed between the plurality of the muffler hole blocks 110 is provided with sound insulation cotton 3 to enhance the sound insulation effect.

[0021] like Figure 2 As shown, one side surface of the plastic sound insulation board body 1 is bonded and covered with an adhesive layer 4, and the adhesive layer 4 is used to bond the plastic sound insulation board body 1 to the surface of the user's product structure.

[0022] Combine Figure 1 and Figure 2 As shown, a tear film 5 is provided on the outer surface of the adhesive layer 4 , and the tear film 5 is provided to protect the outer adhesive surface of the adhesive layer 4 .

[0023] The specific method of use is as follows: before tearing off the tear film 5, the user connects one end of a group of spiral electric heating wires 6 distributed at different locations on one side of the plastic substrate 2 in series, marking them in different colors. Then, the corresponding surface of the plastic sound insulation board body 1 is attached to the surface of the user's product structure. Then, the corresponding spiral electric heating wires 6 connected in series are connected in order to generate heat, which plays the role of heating and softening the plastic structure at the corresponding location. At the same time, external force is applied to ensure that the heated and softened plastic sound insulation board matches the appearance and shape of the product structure. After each part is heated and softened for secondary molding, the user gradually tears off the tear film 5 from the outer surface of the adhesive layer 4 to complete the installation of the entire plastic sound insulation body 1 on the surface of the product structure.

[0024] A manufacturing process for a plastic sound insulation board that can be installed and shaped on site is characterized by the following specific process steps: Step 1: Using two injection molds, a plastic sound insulation board body 1 with distributed sound-absorbing hole blocks 110 and a plastic base plate 2 with distributed circular holes 210 are respectively processed; Step 2: One end of the spiral electric heating wire 6 is fixedly connected to the inside of each circular hole 210 on the plastic substrate 2, and the spiral portion of the spiral electric heating wire 6 contacts the other side surface of the plastic substrate 2; Step 3: Partially remove the injection mold used for the plastic sound insulation board body 1 to expose the other side surface of the plastic sound insulation board body 1, and pre-fix the other side surface of the plastic substrate 2 that contacts the spiral portion of the spiral electric heating wire 6 to the other side surface of the plastic sound insulation board body 1 in an orderly manner; Step 4: Ultrasonic welding is used to weld the plastic substrate 2 and the plastic sound insulation board body 1 together. Step 5: First, fill the space between the plurality of sound insulation holes 110 with sound insulation cotton 3, and then provide an adhesive layer 4 on one side of the plastic sound insulation board body 1; Step 6: Mark one end of a group of spiral electric heating wires 6 distributed in different locations on one side of the plastic substrate 2 in different colors according to the distribution of the lines of the user's product appearance; Step 7: Configure the installation instructions and pack for shipment.

[0025] In summary, the spiral electric heating wire 6 acts on the cross-section between the plurality of silencer hole blocks 110, and is connected in series according to the trend of connecting one end of a group of spiral electric heating wires 6 distributed in different positions on the surface of one side of the plastic substrate 2, and is marked in series with different colors and energized in an orderly manner, thereby heating and softening the plastic structure of the corresponding position. At the same time, with the external force extrusion, the plastic sound insulation board is guaranteed to match the contact shape of the product structure after heating and softening, and the high degree of consistency with the product structure connection is greatly improved, and the function of secondary molding and installation of the straight plastic sound insulation board on site is realized, which solves the problem that the traditional plastic sound insulation board is not highly matched with the shape of the installed structural surface after being molded and delivered to the user for installation, and cannot be proofread and reused, and stacking and transportation are more convenient.
