Description

Technical Field

[0001] The invention relates to the technical field of building materials, in particular to a lightweight plaster putty coating structure integrating waterproof, moisture-proof and sound-insulating functions, aiming to improve the comprehensive performance of a wall, prolong its service life, and optimize the living and working environment. Background Art

[0002] In the field of modern architecture, the performance of walls, as the basic components of buildings, is directly related to the service life, living comfort and energy efficiency of buildings. Although the traditional putty coating structure can meet the requirements of wall flatness and aesthetics to a certain extent, it has obvious deficiencies in waterproofing, moisture-proofing and sound insulation. Especially in humid environments or areas with frequent rain, walls are easily eroded by water vapor, causing the putty layer to fall off and mold, and even affecting the structural safety of the wall. At the same time, with the acceleration of urbanization, noise pollution is becoming more and more serious. The traditional putty coating structure has poor sound insulation effect and is difficult to meet people's demand for a quiet living environment.

[0003] In addition, traditional putty coating structures often use heavier materials, which are difficult to construct, costly, and prone to cracking and falling off, affecting the stability and durability of the wall. Therefore, developing a wall coating structure that is both effective in waterproofing and moisture-proofing, and can significantly reduce noise transmission, while being lightweight, easy to construct, and cost-controlled has become a technical problem that needs to be solved in the current construction field.

[0004] In view of the above problems, there are some attempts in the prior art, such as improving the performance of the wall by adding a waterproof layer and a sound insulation layer, but these solutions often have defects such as complex structure, cumbersome construction, and high cost, and are difficult to be widely promoted and applied. Therefore, there is an urgent need for a new wall coating structure that can comprehensively solve the problems of waterproofing, moisture-proofing, sound insulation, and light weight, so as to meet the high requirements of modern buildings for wall performance. Summary of the invention

[0005] The present invention provides a waterproof, moisture-proof and sound-insulating lightweight plaster putty coating structure, which integrates waterproof, moisture-proof and sound-insulating functions, and aims to improve the comprehensive performance of the wall, prolong the service life, and optimize the living and working environment.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a waterproof, moisture-proof and sound-insulating lightweight plaster putty coating structure, comprising a flexible net, a waterproof coating, a putty powder layer and a paint layer sequentially attached to a base wall in layers; The flexible net forms a plurality of grid-like cavities between the base wall and the waterproof coating.

[0007] In some embodiments, the flexible net is made of fiber material.

[0008] In some embodiments, each of the grid-shaped cavities is filled with sound-absorbing cotton.

[0009] In some embodiments, there are two pieces of sound-absorbing cotton in each of the grid-shaped cavities, and the two pieces of sound-absorbing cotton are arranged at an interval.

[0010] In some embodiments, a wall-solidifying coating is provided between the flexible net and the waterproof coating.

[0011] In some embodiments, the paint layer includes a primer and a topcoat.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The grid-like cavity formed by the flexible net of the present invention acts as a sound insulation layer in the coating, which can absorb and reflect sound waves and significantly reduce noise transmission. In particular, the filling of sound-absorbing cotton and the design of two pieces of sound-absorbing cotton arranged at intervals form a more complex sound wave propagation path, further improving the sound insulation performance of the coating structure. This design enables the coating structure to perform well in reducing noise transmission, providing a more quiet and comfortable space for living and working environments. In addition to having excellent sound insulation performance, the sound-absorbing cotton also has certain thermal insulation performance. It can block the transfer of heat and reduce the temperature exchange between indoors and outdoors, thereby improving the thermal insulation effect of the wall to a certain extent. The space between the two pieces of sound-absorbing cotton also plays a role in heat insulation, reduces energy consumption, and improves the energy saving of living and working environments.

[0019] like Figure 1 As shown, the present embodiment provides a waterproof, moisture-proof and sound-insulating lightweight plaster putty coating structure, comprising a flexible net 1, a waterproof coating 3, a putty powder layer 4 and a paint layer 5 which are sequentially attached to a base wall 100 in layers. The flexible net 1 forms a plurality of grid-like cavities between the base wall 100 and the waterproof coating 3. By arranging the waterproof coating 3 between the base wall 100 and the putty powder layer 4 and using the grid-like cavities formed by the flexible net 1, water penetration is effectively blocked, the waterproof and moisture-proof ability of the coating is improved, and the wall is ensured to remain dry and stable for a long time. The grid-like cavities formed by the flexible net 1 act as a sound insulation layer in the coating, which can absorb and reflect sound waves, significantly reduce noise transmission, and improve the sound insulation performance of living and working environments. In addition, the addition of the flexible net 1 enhances the bonding force between the coatings, reduces the occurrence of problems such as cracking and falling off, improves the stability and durability of the coating, and extends the service life of the wall. The coating structure of the present invention is clearly layered, the construction process is simple and clear, easy to operate and control costs, and is conducive to promotion and application.

[0020] The flexible net 1 of the present invention is laid on the base wall 100 and is tightly combined with the waterproof coating 3. Since the flexible net 1 has certain elasticity and toughness, it can form a number of grid-like cavities between the coatings. These cavities not only reduce the weight of the coating, but also play a role in sound insulation and buffering, effectively absorbing and dispersing sound wave energy, and reducing noise transmission.

[0021] The waterproof coating 3 is evenly applied on the flexible net 1 to form a dense waterproof barrier. The coating has excellent waterproof performance, can effectively block water penetration, and protect the wall from moisture erosion. At the same time, the waterproof coating 3 is closely combined with the flexible net 1, which enhances the overall stability and durability of the coating.

[0022] Moreover, a light plastering gypsum putty powder layer 4 is applied on the waterproof coating 3, and the coating is made of light material and has the characteristics of low density, light weight, easy construction, etc. The putty powder layer 4 is closely combined with the waterproof coating 3 to form a good waterproof, moisture-proof and sound-insulating layer.

[0023] In addition, the paint layer 5 is applied on the putty powder layer 4, which not only plays a decorative role, but also further enhances the waterproof performance and durability of the coating. The paint layer 5 can form a protective film to prevent external pollutants from damaging the coating.

[0024] In summary, the present invention realizes a waterproof, moisture-proof and sound-insulating lightweight plaster putty coating structure through unique structural design and material selection, effectively solves the technical problems existing in the traditional putty powder layer 4 structure, and improves the performance and service life of the wall.

[0025] In some embodiments, the material of the flexible net 1 is a high-strength, corrosion-resistant fiber material, specifically polyester fiber or nylon fiber. Both polyester fiber and nylon fiber have high tensile strength and toughness, which enables the flexible net 1 to more effectively disperse and withstand various stresses in the coating structure, especially when there are small cracks or deformations in the base wall 100, the flexible net 1 can connect the two sides of the crack like a "bridge" to prevent the further expansion of the crack, thereby greatly enhancing the stability and durability of the entire coating structure. Moreover, since polyester fiber and nylon fiber themselves have good water resistance and are not easy to absorb water, swell or rot, the flexible net 1 made of these materials can maintain its shape and performance for a long time, and will not reduce the waterproof and moisture-proof effect due to the erosion of water. At the same time, the fine structure of the fiber material can also block the penetration of water molecules to a certain extent, and work together with the waterproof coating 3 to form a more rigorous waterproof barrier. In addition, the density and elasticity of polyester fiber and nylon fiber are moderate, which can more effectively absorb and reflect sound waves, especially in the grid-like cavity formed, the sound waves gradually decay during multiple reflections and absorption processes, thereby significantly improving the sound insulation performance of the coating. This material property makes the coating structure excellent in reducing noise transmission, providing a quieter and more comfortable space for living and working environments. In addition, the flexible net 1 made of polyester fiber and nylon fiber is light, soft and easy to bend, easy to transport, cut and lay, greatly simplifying the construction process and reducing labor intensity. At the same time, the price of these materials is relatively reasonable, and they have a long service life and low maintenance cost, which has significant economic benefits in the long run.

[0026] In some embodiments, Figure 1As shown in Figure 2, each grid-like cavity is filled with sound-absorbing cotton 101. Sound-absorbing cotton 101 is a highly efficient acoustic material with excellent sound absorption and sound insulation performance. When sound waves enter the grid-like cavity and contact the sound-absorbing cotton 101, the porous structure of the cotton fiber can absorb a large amount of sound wave energy, convert it into heat energy and dissipate it, thereby effectively reducing the reflection and propagation of sound waves. This feature enables the coating structure to show a more outstanding ability in reducing noise transmission, especially in occasions that require high sound insulation, such as theaters, conference rooms, bedrooms, etc., which can significantly improve the comfort of living and working environments. The filling of sound-absorbing cotton 101 not only improves the sound insulation effect, but also further enhances the stability of the coating structure. Sound-absorbing cotton 101 can fill the gaps in the grid-like cavity, reduce the internal stress changes of the coating caused by air flow or temperature changes, thereby reducing the risks of cracking and falling off of the coating. At the same time, the close combination between the sound-absorbing cotton 101 and the flexible net 1, the waterproof coating 3 and the putty powder layer 4 forms a more solid overall structure, which improves the durability and service life of the coating. In addition to its excellent sound insulation performance, the sound-absorbing cotton 101 also has certain thermal insulation properties. It can block the transfer of heat and reduce the temperature exchange between indoor and outdoor, thereby improving the thermal insulation effect of the wall to a certain extent. This feature is particularly important in cold or hot areas, which can reduce energy consumption and improve the energy saving of living and working environments.

[0027] In some embodiments, Figure 2As shown, each grid-shaped cavity is provided with two pieces of sound-absorbing cotton 101, and the two pieces of sound-absorbing cotton 101 are arranged at intervals. The two pieces of sound-absorbing cotton 101 arranged at intervals can form a more complex sound wave propagation path. When the sound wave propagates in the grid-shaped cavity, it will encounter the obstruction and absorption of the two layers of sound-absorbing cotton 101. This multi-layer sound-absorbing structure can more effectively dissipate the energy of the sound wave, reduce the reflection and transmission of the sound wave, and thus further improve the sound insulation performance of the coating structure. Especially in terms of the isolation of low-frequency noise, the two pieces of sound-absorbing cotton 101 at intervals can form a more effective sound insulation barrier, providing a quieter space for living and working environments. Moreover, the two pieces of sound-absorbing cotton 101 are arranged at intervals, which can more evenly distribute the stress in the grid-shaped cavity and reduce the risk of cracking or falling off of the coating caused by single-point force. At the same time, the interval space between the sound-absorbing cotton 101 can also play a buffering role, absorbing and dispersing the stress changes inside the coating, thereby enhancing the overall stability and durability of the coating structure. This design enables the coating structure to maintain better integrity during long-term use and extend the service life of the wall. In addition, the space between the two pieces of sound-absorbing cotton 101 forms a certain air layer, which can play a role in heat insulation during heat transfer and reduce the exchange of heat between indoor and outdoor. At the same time, the air layer can also hinder the penetration of moisture, and work together with the waterproof coating 3 and the sound-absorbing cotton 101 to form a more rigorous waterproof and moisture-proof barrier. This feature is particularly important in humid environments or places that require high thermal insulation, and can significantly improve the thermal insulation and moisture-proof performance of the wall.

[0028] In some embodiments, Figure 1 As shown, a wall-solidifying coating 2 is provided between the flexible net 1 and the waterproof coating 3. As an interface treatment agent, the wall-solidifying coating 2 can penetrate the surface of the base wall 100, form a strong chemical bond with it, and tightly bond with the flexible net 1. This double bonding effect significantly enhances the adhesion between the base wall 100 and the entire coating structure, reduces the risk of cracking and shedding of the coating due to quality differences of the base wall 100 or shrinkage of the coating material, thereby improving the stability and durability of the coating structure. The wall-solidifying coating 2 usually has a certain waterproof performance and can form an additional waterproof barrier between the base wall 100 and the waterproof coating 3. This barrier can effectively prevent moisture from penetrating upward from the base wall 100, and cooperate with the waterproof coating 3 to form a more rigorous waterproof and moisture-proof system. Especially in humid environments or places susceptible to water vapor erosion, the addition of the wall-solidifying coating 2 can significantly improve the waterproof and moisture-proof ability of the coating structure, ensuring that the wall remains dry and stable for a long time. Moreover, the wall-solidifying coating 2, as a transition layer between the flexible net 1 and the waterproof coating 3, can evenly distribute the stress in the coating structure and reduce the stress concentration caused by differences in material properties or improper construction. This stress dispersion effect helps reduce the risk of cracking and deformation of the coating and improves the overall stability and service life of the coating structure.

[0029] In some embodiments, the paint layer 5 includes a primer and a topcoat. As the first layer of the paint layer 5, the primer can penetrate into the surface of the putty powder layer 4, form a strong chemical bond with it, and significantly enhance the adhesion between the paint layer 5 and the putty powder layer 4. This strong adhesion reduces the risk of cracking and falling off caused by material performance differences or environmental changes between the coatings, and improves the stability and durability of the entire coating structure. At the same time, the primer can also close the surface pores of the putty powder layer 4, provide a flat and uniform base for the subsequent construction of the topcoat, and ensure that the coating effect of the topcoat is more beautiful and durable. The primer usually has certain waterproof and moisture-proof properties, and can form an additional waterproof barrier between the putty powder layer 4 and the topcoat. This barrier works in synergy with the waterproof coating 3 and the putty powder layer 4, further enhancing the waterproof and moisture-proof ability of the coating structure, ensuring that the wall can remain dry and stable in a humid environment or in severe weather conditions. In addition, the primer can also improve the weather resistance of the coating structure, resist the erosion of natural factors such as ultraviolet rays and weathering, and extend the service life of the coating. As the last layer of the paint layer 5, the topcoat is directly exposed to the outdoor environment, and its coating effect and performance are crucial. The addition of primer provides a smooth and uniform substrate for the topcoat, making the coating of the topcoat easier and more uniform, avoiding the coating defects such as orange peel and sagging. At the same time, the primer can also improve the adhesion, hardness and wear resistance of the topcoat, making the coating structure more solid and durable, and resisting the external forces such as scratches and collisions in daily use. As the final decorative layer of the coating structure, the topcoat has a rich selection of colors and textures. By selecting topcoats of different colors, glossiness and textures, different architectural styles and decorative requirements can be met, and aesthetic and personalized elements are added to the living and working environment. The addition of primer provides a more stable and lasting substrate for the color and texture performance of the topcoat, ensuring that the decorative effect of the coating structure remains bright and beautiful for a long time.
