Description

Sound insulation structure

This creation relates to a sound insulation structure, especially to a sound insulation structure for buildings.

In order to improve the quality of domestic housing, the Ministry of Internal Affairs and Construction of the Republic of China formulated the "Building Technical Regulations Architectural Design and Construction", and its Article 46-6 records relevant regulations for the impact sound and sound insulation structure of household floor slabs. Among them, "Building Technical Regulations, Building Design and Construction" Article 46-6, Paragraph 1, paragraph 7 stipulates: "Surface materials (including cushioning materials) approved by the central competent construction authority, the impact sound reduction index of the floor surface materials ( △Lw) above 17 decibels, or high-performance green building materials (sound insulation) that have obtained the green building materials label from the Ministry of the Interior.

It should be noted that the existing building floor slabs are mainly equipped with rubber buffer materials (such as rubber sound insulation pads) and glass fiber cotton buffer materials and other sound insulation materials to reduce the transmission of impact sound waves and enhance the sound insulation effect of the existing building floor slabs. However, the existing rubber buffer material or glass fiber cotton buffer material and other common materials, due to the small area of a single sheet, construction personnel have to spend more construction time to lay multiple sheets of buffer material on the floor.

In addition, when laying sound insulation materials on existing building floor slabs, it is often necessary to use an additional layer of cement mortar as an adhesive so that the sound insulation materials can be stably installed on the floor slab. However, the use of cement mortar not only increases additional costs, but also causes inconvenience to the constructor in carrying and laying.

In addition, since there are currently hundreds of different types of sound insulation materials that have passed government inspections, there may not be precedents to follow when actually constructing and selecting a variety of sound insulation materials. As a result, when multiple sound insulation materials are used together, it is easy to The "uneven degree of softness and hardness" caused the tiles adjacent to the sound insulation material to crack.

For example, most of the existing sound insulation pads are relatively soft materials. When an earthquake comes, soft sound insulation materials such as sound insulation pads will produce relatively large displacements during vibration, which directly or indirectly causes hard materials (such as tiles) to crack or hollow at the joints. In other words, when an earthquake strikes, the tiles set on the soundproofing material are like the uppermost layer of sandwich biscuits. The displacement of the soundproofing material under the tiles creates voids, making the tiles easy to break when shaken.

As mentioned above, when an earthquake comes, tiles installed with existing sound insulation materials are prone to cracks or bursts due to misalignment, which in turn leads to increased follow-up maintenance costs of the tiles. Therefore, providing a sound insulation structure and its manufacturing method that comply with current laws and regulations and is easy to install has become one of the important issues that this business intends to solve.

The embodiment of the present invention provides a sound insulation structure in view of the shortcomings of the prior art, which can effectively improve the possible defects of the existing sound insulation structure.

This creative embodiment discloses a soundproof structure that can be used to install on a floor. The soundproof structure includes: a soundproof cement layer with a first surface and a second surface on opposite sides, and the second surface can be Used to install on the floor; wherein, the sound insulation cement layer is composed of cement, rubber particles, resin powder, glass fiber, fiber filler, and rheology additives; an adhesive layer is provided on the sound insulation The first surface of the cement layer; and an adhesive layer disposed on a side of the adhesive layer relatively far away from the first surface.

The cement composition is in powder form, and the cement composition can be mixed with water and hardened to form a sound insulation cement layer 2. Wherein, in this embodiment, the constituent materials of the cement composition are dry-mixed to be uniformly mixed and then packaged. Thereby, the cement composition is convenient to be transported, and the builder does not need to perform on-site proportioning when using the cement composition, effectively avoiding the problem of incorrect material proportioning.

Specifically, the cement composition includes 100 parts by weight of cement, 23 to 157 parts by weight of rubber particles, 1.5 to 14 parts by weight of resin powder, 5 to 20 parts by weight of glass fiber, and 1.5 to 8.5 parts by weight of fiber.

For example, the material type of the resin powder can be adjusted according to actual needs, or the resin powder can also be made by mixing two or more resins.

Furthermore, due to the different physical properties of cement and rubber particles, if the cement composition is not added with resin powder, the cement composition will harden and correspondingly form the sound insulation cement layer 2. The cement and rubber particles may interact with each other. Separate. Therefore, it is necessary to add resin powder to the cement composition (the sound-insulating cement layer 2) to prevent the cement and rubber particles from separating from each other. On the other hand, soundproof cement that does not contain resin powder is not the cement composition (the soundproof cement layer 2) referred to in this creation.

It is worth mentioning that if the resin powder in this embodiment is replaced with a liquid resin, the manufacturing cost of the cement composition may increase. In addition, because the liquid resin contains a large amount of water, the liquid resin will cause inconvenience to the constructor (such as: difficult to carry or wrong proportion of ingredients) when carrying and packaging the liquid resin. Therefore, in this embodiment, the cement composition preferably adopts a "solid" resin powder.

It should be noted that the rheological additives are selected from sulfonated naphthaleneformaldehyde condensates (SNF), Amino sulphonateformaldehyde condensates (ASF), and polycarboxylic ether comb copolymers. (Polycarboxylate ether comb copolymers, PCE), and the rheology adjuvant in this embodiment is preferably a polycarboxylate comb copolymer.

Specifically, in the process of general mixing of cement, it is necessary to continuously add water to help the cement to be mixed with other materials, because water will quickly evaporate and lose during the mixing of materials. In addition, the cement needs to be sprinkled for curing after it is formed, which consumes a lot of time and energy. On the contrary, the rheology additive in the cement composition of this embodiment can absorb water and continuously supply water for cement hydration through the absorbed water during the mixing and stirring process, thereby prolonging the operability of the cement during mixing. time.

It is worth mentioning that when the cement composition is hardened and the sound-insulating cement layer 2 is formed, the rheological additive can help other materials in the sound-insulating cement layer 2 to be tightly combined with each other, leaving micron-level closed pores (That is, the rubber particles are tightly covered by cement), so that the sound-insulating cement layer 2 is not easy to crack. Furthermore, through the technical means of "the cement composition contains rheological additives", the dynamic rigidity and compressive resistance of the soundproof cement layer 2 will be effectively improved and balanced with each other, which is beneficial to the soundproof cement The ability of layer 2 to multiply the load capacity.
