Problems solved by technology

[0009] However, due to the current aggravation of urbanization, the residents living in the city are under a lot of work pressure, and they need a quieter environment when they return home to rest. The processing technology of similar sound insulation panels is not mature enough, the seismic performance of the sound insulation panels is poor, and it is easy to crack; there are many human factors in the processing and production process, which often affect the quality of the final sound insulation panels, for example, the sound insulation of different positions of a sound insulation panel The effect is different. When laying floor tile mortar for interior decoration, it is easy to penetrate into the sound insulation pad to form a sound bridge, which affects the sound insulation performance.
At the same time, in the process of processing, irritating gas will be produced, which will affect the health of workers

preparation example Construction

[0043] The preparation method of rubber granule sound-insulating coiled material comprises the following steps:

[0044] Material selection: Prepare rubber particles with a particle size of 0.3-0.4mm, 0.8-1.2mm, and 3-3.5mm, mix them in a mass ratio of 1:4:15-1:5:20, and add the adhesive after mixing evenly ;

[0045]In order to improve the quality of the sound insulation coil, the heat-curable elastic polyurethane, or heat-curable elastic resin, or elastic UV light-curable resin is environmentally friendly and has no peculiar smell. Professional testing and ROS certification testing are carried out. These materials have no volatile matter , does not contain heavy metals. Therefore, it is preferable that the adhesive is heat-curable elastic polyurethane, or heat-curable elastic resin, or elastic UV light-curable resin.

[0046] Among them, the adhesive and rubber particles of different particle sizes need to be fully fused and bonded. At the same time, in order to increase t...

Embodiment 1

[0062] Material selection: Prepare rubber particles with particle sizes of 0.3mm, 0.8mm, and 3mm, mix them according to the mass ratio of 1:4:15, and use a mixer to mix for 5 minutes until uniform, then add heat-cured elastic polyurethane, or heat-cured Elastic resin, or an adhesive made of elastic UV light-curable resin; wherein, the mass ratio of the total amount of rubber particles to the added adhesive is 6:1.

[0063] Substrate production: spread the mixture of the rubber particles and the adhesive on the non-woven substrate film impregnated with the above adhesive, and send it to an oven for curing after rolling and defoaming. The base is completed.

[0064] Extrusion and rolling: Send the prepared tire bases to the extruder equipped with UV curing box and pressurize. The pressure during extrusion is 10Mpa, and then sent to the rolling machine for rolling; rolling When the pressure is 3010Mpa.

[0065] Curing: After the pressing, it is sent to the UV curing box again, ...

Abstract

The invention belongs to the field of sound insulation material processing, and particularly relates to a rubber particle sound insulation coiled material and a preparation method thereof. The performance of a final product is improved. The preparation method comprises the following steps: material selection: preparing rubber particles with the particle sizes of 0.3-0.4 mm, 0.8-1.2 mm and 3-3.5 mm, mixing in a mass ratio of 1: 4: 15 to 1: 5: 20, and adding an adhesive after uniformly mixing; manufacturing of base materials: spreading out the mixture of the rubber particles and the adhesive on the thin films of the base materials soaked by using the adhesive, and feeding in a curing device after rolling defoaming for curing to complete the manufacturing of the base materials; extrusion and rolling: successively feeding the manufactured base materials into extrusion forming equipment and rolling equipment for pressing; curing: feeding in the curing device again for curing after pressing; laminating: after curing, pasting protective films on the surfaces of the formed base materials.

Description

technical field [0001] The invention belongs to the field of sound-insulating material processing, and in particular relates to a rubber particle sound-insulating coiled material and a preparation method thereof. Background technique [0002] General objects have sound insulation effect, but we only call the board with the average sound insulation (in an infinite space, an infinite material between the sound source and the measured point) more than 30dB as a sound insulation board. Sound insulation panels are generally high-density materials. Sound is a wave-like energy that requires a medium to travel. When sound propagates in the same medium, the denser the medium, the faster the propagation speed. For example, the propagation speed in air at normal temperature is about 340 m / s, and the propagation speed in railroad tracks is about 5200 m / s. Another kind of propagation of sound is the propagation across media. That is to say, from one medium to another medium through t...
