Problems solved by technology

The vibration and sound insulation block currently used is a rubber block (the specification is 50mm*50mm*50mm). When the rubber is not aged, the rubber block has a good isolation effect on low-frequency noise and can reduce low-frequency noise by about 25dB. However, due to the presence of air With the action of oxygen, ozone and other gases and the action of moisture, the rubber block will quickly age and harden (lose elasticity), which reduces the attenuation effect on low-frequency noise (experimentally measured 50mm*50mm*50mm rubber block after one year of use) , the attenuation of low-frequency noise is reduced from 25dB to below 20dB), the service life is short, and when the rubber ages to crack, it may even cause the floating structure to collapse
The price of the rubber block itself is not low. It has cost the owner a lot of money to lay a large area of ​​floating structures in the equipment room, and replacing the aging rubber blocks will consume a lot of money and energy of the owner. owner satisfaction

Embodiment 1

[0023] After recycling waste tires, crush them into rubber particles with a diameter of about 10mm. After the crushing is completed, select cork particles with a diameter of about 10mm, and mix the cork particles, rubber particles, and water-based glue in a ratio of 2:2:1, and the mixing is completed. Then it is placed in a container and heated so that the temperature of the mixture is maintained at 150°C. Stir while heating. After stirring for 70min, stop heating and apply a pressure of 9000Pa to the mixture. When the mixture is cooled to 25°C (at this time The mixture has cooled into a block), the pressurization is stopped, and the block mixture is cut into cubes of 50mm size. The detection of low-frequency noise attenuation is carried out in accordance with GBJ75-1984 and GB / T19889.6-2005.

Embodiment 2

[0027] After the waste cable sheath is recovered, it is crushed into rubber particles with a diameter of about 5mm. After the crushing is completed, cork particles with a diameter of about 10mm are selected, and the cork particles, rubber particles, and water-based glue are mixed in a ratio of 3:2:2. After completion, it is placed in a container and heated so that the temperature of the mixture is maintained at 140 ° C. Stir while heating. After stirring for 90 minutes, stop heating and apply a pressure of 7000 Pa to the mixture. When the mixture is cooled to 25 ° C (this When the mixture has cooled into a block), the pressurization is stopped, and the block mixture is cut into cubes of 50mm size. The detection of low-frequency noise attenuation is carried out in accordance with GBJ75-1984 and GB / T19889.6-2005.

[0032] After recycling the rubber soles of waste rubber shoes, crush them into rubber particles with a diameter of about 8mm. After the crushing is completed, select cork particles with a diameter of about 8mm, and mix the cork particles, rubber particles, and water-based glue in a ratio of 4:2:3. After the mixing is completed, place it in a container and heat it so that the temperature of the mixture is maintained at 170 ° C. Stir while heating. After stirring for 120 minutes, stop heating and apply a pressure of 5000 Pa to the mixture. When the mixture is cooled to 25 ° C (at this moment, the mixture has cooled to block), the pressurization is stopped, and the block mixture is cut into cube blocks of 50mm size. The detection of low-frequency noise attenuation is carried out in accordance with GBJ75-1984 and GB / T19889.6-2005.

Abstract

The invention discloses a manufacturing method for spot irradiating type floating floor vibration isolation and sound insulation blocks. The method comprises the following steps that rubber particlesand softwood particles are mixed, then glue is added, a mixture of the rubber particles, the softwood particles and the glue is put in a container, the temperature of the container is kept at 30 DEG C-300 DEG C, then stirring is conducted for 5 min-600 min, after stirring is completed, 50Pa-10000Pa pressure is applied to the mixture for pressure cooling, pressurization is stopped when the mixtureis cooled to 25 DEG C, and the mixture is cut into pieces. The method has the following beneficial effects that a good attenuation effect on low frequency noise is realized, after the spot irradiatingtype floating floor vibration isolation and sound insulation blocks ( with the specification of 50mm*50mm*50mm) are installed in a floating building, the low frequency noise can be attenuated by morethan 27dB, the service life is long, cracking is not prone to occurring, the low frequency noise can be attenuated by more than 25dB after one-year use, the attenuation capacity of the low frequencynoise hardly changes, and good humidity resistance and fire resistance are realized.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a method for manufacturing point-shaped floating floor slab vibration and sound insulation blocks. Background technique [0002] Many equipment (such as compressors, air conditioners, water pumps, fans, washing machines, boilers and transformers, etc.) will generate vibration and low-frequency noise (frequency below 200Hz) during work, and if people are in a low-frequency noise environment for a long time, Symptoms of neurasthenia such as dizziness, headache, insomnia, dreaminess, memory loss, inattention, etc. and gastrointestinal symptoms such as nausea, vomiting, stomach pain, abdominal distension, and sluggish appetite may appear. In recent years, due to land constraints, there have been more and more steel structure buildings and super high-rise intelligent buildings. Due to space constraints, various power equipment in the buildings are often placed on the top floor of th...
