Some embodiments of the invention are described in detail below with reference to the accompanying drawings. Features in the embodiments described below may be combined with each other without conflict.
Referring to fig. 1, an embodiment of the present invention provides a vibration-damping and noise-reducing pad for a user to perform a fitness exercise. It has good damping and the performance of making an uproar of falling, and the noise cancelling effect is good, can avoid producing the noise and cause the influence to other people, and user experience is good.
The vibration and noise reduction pad is prepared from the following raw materials in parts by weight: 14 parts of basic preparation, 4 parts of vibration damper, 1 part of chemical auxiliary agent and 1 part of pigment agent. Specifically, because the noise mainly arouses by the vibration, adopt damping can effectual suppression resonance to the noise reduction, so in this application, added the vibration damping agent in the preparation raw materials, improved the damping performance of the pad of making an uproar that falls in the damping, help reducing because of the sound radiation that the vibration produced, thereby the noise reduction improves noise cancelling effect, avoids causing the influence to other people.
In the embodiment, the basic preparation is made of thermoplastic elastomer (TPE), and the TPE has various excellent properties of high elasticity, aging resistance, oil resistance and the like of the conventional crosslinked vulcanized rubber, and has the characteristics of convenience in processing and wide processing mode of common plastics, and is convenient and practical. But not limited thereto, in other embodiments, the base formulation may be made of vinyl acetate copolymer (EVA), polyvinyl chloride (PVC), or Polyethylene (PE), and the material of the base formulation is not particularly limited.
In this example, the vibration damper was made of hydrogenated styrene butadiene block copolymer (SEBS). The hydrogenated styrene butadiene block copolymer has excellent aging resistance, plasticity and high elasticity, can be processed and used without vulcanization, has good weather resistance, heat resistance, compression deformation resistance and excellent mechanical property, and can improve the damping performance of the vibration and noise reduction pad, thereby realizing the vibration and noise reduction function.
It should be noted that, the density of the vibration and noise reduction pad is greater than or equal to 160 kg/cubic meter, and the high-density vibration and noise reduction pad can further improve the noise reduction effect and avoid causing noise influence. Specifically, when sound is transmitted into the surface of the vibration and noise reduction pad, one part is reflected, and the other part penetrates through the vibration and noise reduction pad.
In the present embodiment, the density of the vibration and noise reduction pad is 160 kg/cubic meter, but the density is not limited thereto, and in other embodiments, the density of the vibration and noise reduction pad may be 180 kg/cubic meter, or may be 200 kg/cubic meter, and the density of the vibration and noise reduction pad is not particularly limited.
In this embodiment, the inside of the vibration and noise reduction pad is cellular, and the inside of the vibration and noise reduction pad is provided with a plurality of open pores which are communicated with each other inside, so that when sound waves enter the pores of the vibration and noise reduction pad, the sound waves are subjected to friction and viscous resistance of air molecules and drive the fine fibers to perform mechanical vibration, so that sound energy is converted into heat energy, and vibration and generated noise are reduced.
The embodiment of the invention also provides a production method of the vibration and noise reduction pad, which is used for producing the vibration and noise reduction pad and comprises the following steps:
step S101: mixing the vibration damper, the basic preparation, the chemical auxiliary agent and the pigment agent to form a preparation raw material.
In step S101, the base formulation, the vibration damper, the chemical additive, and the pigment agent are mixed in a mass ratio of 14:4:1:1 to form a preparation raw material. Wherein the basic preparation is made of thermoplastic elastomer (TPE) and is used as a main production raw material of the vibration and noise reduction pad; the vibration reducer is made of hydrogenated styrene butadiene block copolymer (SEBS), and is used for improving damping performance so as to realize the functions of vibration reduction and noise reduction; the chemical auxiliary agent is used for improving the production process and improving the production efficiency; the pigment agent is used for regulating and controlling the color of the vibration and noise reduction pad.
Step S102: and banburying and open mixing are carried out on the preparation raw materials to form a rubber blank.
Specifically, step S102 includes two steps, which are respectively:
step S1021: plasticating the preparation raw materials by using an internal mixer under the dustless condition to form the master batch.
In step S1021, the raw materials for preparation are plasticated with an internal mixer under a dust-free condition. Specifically, the internal mixer is provided with a pair of rotors of a specific shape and relatively rotatable, which can masticate and mix the polymer material intermittently in a closed state with adjustable temperature and pressure. When the internal mixer works, the two rotors rotate relatively to clamp the preparation raw material from the feed inlet and bring the preparation raw material into a roll gap, in the process, the preparation raw material is extruded and sheared by the rotors and is divided into two parts under the action of a lower top bolt sharp edge after passing through the roll gap, the two parts of the preparation raw material respectively return to the upper part of the roll gap along the gap between the front and rear chamber walls and the rotors and are extruded and sheared by the rotors again, and the steps are repeated, so that plastication of the preparation raw material is realized, and master batch is formed. Further, during one week of the revolution, the preparation raw materials are subjected to shearing and friction everywhere, so that the temperature of the preparation raw materials is sharply increased, the viscosity is reduced, the wettability of the base preparation on the surface of the vibration reducer is increased, and the base preparation is fully contacted with the surface of the vibration reducer.
Step S1022: and mixing the master batch by using an open mill to form a rubber blank.
In step S1022, the master batch is kneaded by an open mill. Specifically, the main working components of the open mill are two hollow rollers which rotate inwards in different directions, the two rollers are the same in size and rotate relatively at different speeds, and one roller can be close to or far away from the other roller so as to adjust the gap between the two rollers. The master batch is rolled into a gap between the two rollers along with the rotation of the rollers, and the two rollers apply larger shearing acting force to the master batch simultaneously so as to realize the mixing of the master batch and form a rubber blank. Further, during the rotation of the roller, the base agent, the vibration damper and other various agents are thoroughly mixed and preliminarily crosslinked.
Step S103: and cutting the rubber blank to a preset thickness by using a water-cooled piece discharging machine.
In step S103, since the thickness of the rubber blank is large, in order to facilitate the vulcanization process, the rubber blank needs to be cut first so that the rubber blank becomes a sheet by sheet, thereby obtaining a sheet-like rubber blank. Specifically, water-cooled pelleter is equipped with discoid cutting blade, and discoid cutting blade rotates at a high speed under the motor drives to cut into slice with the rubber base, at the tapping in-process, utilize water-cooled mode to cool off heat dissipation to discoid cutting blade, reduce discoid cutting blade's temperature, prolong discoid cutting blade's life, improve cutting efficiency.
Step S104: and vulcanizing the rubber blank by using a flat vulcanizing machine to generate the vibration and noise reduction pad.
Specifically, step S104 includes three steps, which are respectively:
step S1041: and placing the rubber blank into a foaming mold.
In step S1041, the sheet-like rubber blank is placed in a foaming mold, and the foaming mold is placed between two hot plates of a press vulcanizer, so that the opening and closing of the foaming mold are performed.
Step S1042: and closing the mold, heating and pressurizing the rubber blank to foam the rubber blank, and filling the foaming mold with the rubber blank.
