Problems solved by technology

[0002] In the currently recommended soundproof door design, generally 4cm thick rigid board is used as the door panel or cement is poured inside the door panel to improve the quality and achieve a higher sound insulation effect. However, the sound insulation effect is achieved, but the weight of the door panel will indeed increase the door. The burden of the foot chain, if the hinge cannot be fully loaded, the door leaf cannot be opened and closed easily or even the hinge will be damaged. When the soundproof door is closed, there will be gaps around the sound insulation effect. Opening the door will cause damage to the rubber sealing strip, so we propose a soundproof door

Embodiment 1

[0021] The preparation method of nano sound insulation board, this method comprises the following steps:

[0022] Step 1. Weigh 14 parts of thermoplastic elastomer (POE), 28 parts of MOF-SO 3 @TS-1 nanomaterials, 14 parts of dioctyl phthalate and 3 parts of calcium-zinc stabilizer were mixed in a high-speed mixer at 1500rpm for 5 minutes, then 2 parts of citrate plasticizer were added to continue mixing, and then 42 Parts of barium sulfate granules, 2 parts of stearic acid, 20 parts of polyoxyethylene, and 0.5 parts of azodicarbonamide continue to mix at high speed until the temperature reaches 128°C, and then discharge;

[0023] Step 2. Add the above-mentioned mixed raw materials into the twin-screw extruder to extrude and granulate. The temperature of each section of the extruder: 135°C; 145°C; 140°C; 140°C; die 150°C; screw speed 35rpm;

[0024] Step 3. Add the above-mentioned pellets to a single-screw extruder for melting and plasticization, and then feed the material to ...

Embodiment 2

[0030] Step 1. Weigh 7 parts of thermoplastic elastomer (POE), 27 parts of MOF-SO 3 @TS-1 nanomaterials, 14 parts of dioctyl phthalate and 3 parts of calcium-zinc stabilizer were mixed in a high-speed mixer at 1500rpm for 5 minutes, then 2 parts of citrate plasticizer were added to continue mixing, and then 42 Parts of barium sulfate granules, 2 parts of stearic acid, 20 parts of polyoxyethylene, and 0.5 parts of azodicarbonamide continue to mix at high speed until the temperature reaches 128°C, and then discharge;

[0031] All the other preparations are the same as in Example 1.

Embodiment 3

[0033] Step 1. Weigh 14 parts of thermoplastic elastomer (POE), 21 parts of MOF-SO 3 @TS-1 nanomaterials, 7 parts of dioctyl phthalate and 3 parts of calcium-zinc stabilizer were mixed in a high-speed mixer at 1500rpm for 5 minutes, then 2 parts of citrate plasticizer were added to continue mixing, and then 42 Parts of barium sulfate granules, 2 parts of stearic acid, 20 parts of polyoxyethylene, and 0.5 parts of azodicarbonamide continue to mix at high speed until the temperature reaches 128°C, and then discharge;

[0034] All the other preparations are the same as in Example 1.

Abstract

The invention discloses a soundproof door in the technical field of soundproof doors. A rotating handle is arranged on the front end of the gear, the top of the gear is movably connected to a first connecting rod, the left side of the gear is movably connected to a second connecting rod, and the right side of the gear is arranged There is a third connecting rod, and the bottom of the gear is movably connected to the fourth connecting rod. Rubber sealing strips are arranged around the front end of the inner cavity of the soundproof door body, and the ends of each group of rubber sealing strips away from the soundproof door body are connected to the first connecting rod respectively. The second connecting rod, the third connecting rod, and the fourth connecting rod are connected. The inner cavity of the soundproof door body includes a soundproof layer, and the rear end surface of the soundproof door body is provided with a nano-sound-insulating board. The board greatly reduces the weight of the soundproof door, making it easier and labor-saving to move the soundproof door. At the same time, there are gears, racks and rubber sealing strips in the inner cavity of the door, and a rotating handle is provided to control the rotation of the gears to move each set of rubber seals. strip.

Description

technical field [0001] The invention relates to the technical field of soundproof doors, in particular to a soundproof door. Background technique [0002] In the currently recommended soundproof door design, generally 4cm thick rigid board is used as the door panel or cement is poured inside the door panel to improve the quality and achieve a higher sound insulation effect. However, the sound insulation effect is achieved, but the weight of the door panel will indeed increase the door. The burden of the foot chain, if the hinge cannot be fully loaded, the door leaf cannot be opened and closed easily or even the hinge will be damaged. When the soundproof door is closed, there will be gaps around the sound insulation effect. Opening the door will damage the rubber sealing strip, so we propose a soundproof door. Contents of the invention [0003] The object of the present invention is to provide a soundproof door to solve the problems raised in the above-mentioned background...
