Description

Sound insulation mat multi-layer structure

This creation is about the multi-layered structure of the sound-insulating mat, especially a sound-insulating layer mat structure that prevents liquid from penetrating into the sound-insulating layer and ensures the overall sound-insulating effect.

In order to solve the noise interaction between the residents of the collective housing and the living peace, the current building regulations require that the sound insulation effect between the floor slabs separating the upper and lower floors must be kept at Below a predetermined value (58 decibels), and in order to meet the above-mentioned sound insulation requirements, the relevant construction industry is currently setting up sound-absorbing pads with sound-absorbing and cushioning effects between the floors of buildings to achieve the preset sound insulation requirements. Noise reduction effect and meet the regulations.

The sound insulation pads used in the sound insulation of floor boards in the early days were mostly made of foam materials. However, due to the poor structural strength of many foam materials, they are often used for a long time or the effect of stress concentration, which may easily cause partial or overall damage to the sound insulation pad. In the case of collapse, severe cases may even cause rupture and damage to the sound insulation pad, which requires time-consuming and labor-intensive inspection and repair.

There is also a sound-insulating mat structure with rubber as the main component. Although it can achieve a certain sound-insulating and shock-absorbing effect, due to the hard rubber material, it cannot fit on the protrusions or depressions of the floor and easily forms gaps, and the sound is easy to pass through the gaps. Reduce the performance of the overall sound insulation and noise reduction, and the weight of the rubber material is heavy, which increases the inconvenience of construction and transportation.

In the patent announcement No. I752806 of the Republic of China, a "sound-insulating layer structure of the floor" is disclosed, which mainly consists of two-sided substrates covering the upper and lower sides of a sound-insulating medium material to form a sound-insulating pad Body, the sound insulation material system can be made of porous fiber material (such as: polyester fiber Polyester, polyethylene PE, ethylene / vinyl acetate copolymer EVA, polypropylene PP, etc.) or polyolefin foam material (such as: IXPE; EVA Foaming material), there are densely connected pores inside the sound insulation material, which can achieve a certain degree of sound absorption effect; and the surface substrate is made of porous fiber cloth (such as: non-woven fabric, woven fabric, woven fabric etc.) or polyester cotton, its surface forms capillary fibers, which have excellent bonding with concrete.

Since the materials of the above-mentioned surface substrate and the sound insulation medium material are not waterproof, in actual application, it is very easy for the liquid (water or cement mortar) in the construction process to penetrate into the sound insulation medium material through the surface substrate, resulting in The sound-insulating middle material hardens or deteriorates, thereby affecting the overall sound-insulating effect; material), so as to prevent the liquid from penetrating into the sound insulation material and causing structural damage.

However, although the general waterproof layer (such as: polyethylene PE) material is not easy to combine with the surface substrate and the sound insulation material, if it is combined with glue, the production speed will be greatly limited. The sound insulation middle material and the upper and lower waterproof layers are combined by hot pressing first, but the bonding between the waterproof layer and the surface substrate (such as: non-woven fabric, woven fabric, woven fabric and other porous fiber cloth) is still not good. The common one is to use glue to achieve a stable combination between the two, and the problem of time-consuming processing or construction has not been perfectly solved; therefore, how to integrate the above-mentioned different materials and structures so that each layer structure can be quickly and conveniently It is an urgent task for relevant industry players to combine stably and generate preset functional characteristics so as to improve the deficiencies of the above-mentioned conventional knowledge.

In view of the above-mentioned shortcomings in the combined structure of the common sound-insulating layer mat and the relevant subsidiary layers in application, the creator studies the improvement method for these shortcomings, and finally this creation is produced.

The main purpose of this creation is to provide a multi-layered structure of a sound-insulating pad, in which the upper and lower surfaces of a sound-insulating layer are respectively provided with the first and second isolation layers with waterproof properties, so as to effectively prevent water or cement mortar from penetrating into the sound-insulating layer. Destroy its structure, and above the first isolation layer, combine a protective layer through a bonding layer, the bonding layer has fast and good bonding with the protective layer and the first isolation layer, so that the The protection layer forms a good bonding effect with the first isolation layer through the bonding layer, which effectively solves the problem of poor bonding between the first isolation layer and the protection layer; and the protection layer has better toughness It can withstand the extrusion and friction of cement and sand during construction, and achieve the best overall combination and protection effect.

Another purpose of this creation is to provide a multi-layered structure of the sound-insulating mat, wherein one of the first and second insulating layers is made of a material with both sound-insulating and waterproof properties, so that the sound-insulating effect of the overall sound-insulating layer mat is better. for promotion.
