Description

A waterproof and moisture-proof composite insulation board

Technical Field

The utility model relates to the technical field of thermal insulation boards, in particular to a waterproof and moisture-proof composite thermal insulation board.

Background technique

Insulation board has a wide range of uses. It can be used for building insulation, including walls, roofs and floors. In terms of wall insulation, insulation board can be installed on the inside or outside of the exterior wall to reduce heat conduction and improve the building's insulation performance. In terms of roof insulation, insulation board can prevent heat from transferring between the roof and indoor space, playing a role in heat insulation. Composite insulation board is also a common insulation material. It is composed of multiple layers of materials and has better insulation performance and strength.

According to the announcement number: CN215926352U, a composite insulation board with waterproof joints includes: a mounting plate, in which a composite insulation board body is embedded and arranged inside, and a fixing block for installation is fixedly connected to the outer side of the left end of the mounting plate, and a fixing rod is connected through the inside of the fixing block; a connecting groove is opened on the outer side of the right end of the mounting plate, and a first sealing strip is installed on the left end face of the mounting plate, and a second sealing strip is installed on the right end face of the mounting plate; mounting grooves are opened on the inner side of the right end of the mounting plate at equal intervals, and a mounting assembly installed on the outer side of the left end of the mounting plate is arranged inside the mounting groove, and sealing grooves are arranged on both sides of the mounting plate, and the fixing block and the fixing rod are connected by threads. The composite insulation board with waterproof joints strengthens the sealing effect of the joints, avoids water seepage during use, and at the same time improves the firmness of the installation and prolongs its service life; however, the existing insulation boards still have the following defects during actual use:

1. Insulation boards are mainly used to provide thermal insulation effects, and relatively little consideration is given to sound insulation performance. If the sound insulation performance of the insulation board is poor, it may not be able to effectively reduce the spread of noise, leading to indoor noise problems.

2. Buildings will be affected by the external environment, such as temperature changes, which will cause thermal expansion, contraction and deformation of the building, resulting in a weakening of the structural strength of the insulation board, which poses a potential threat to the overall stability and safety of the building.

3. The existing insulation boards have poor fire retardant effects and may not provide adequate fire protection when a fire occurs, which may increase the risk of fire spread and pose a threat to the safety of buildings and personnel.

In order to increase the structural strength of the insulation board and prevent the influence of external factors, we use a crack-resistant adhesive layer with high adhesion and flexibility, and wrap multiple layers of alkali-resistant glass fiber mesh layers to enhance the crack resistance.

1. By setting up sound-absorbing supports and cavities, the problem of poor sound insulation performance, which leads to the spread of noise and affects people's use, can be solved. During people's use, the object resonance frequency is formed by the sound-absorbing supports, and the sound close to the object resonance frequency can be reduced, thereby increasing the sound insulation effect. The cavity set inside the sound-absorbing supports can form an isolation barrier on the sound propagation path to block the propagation of sound. The sound will be reflected, scattered and absorbed many times in the cavity, thereby weakening the energy of the sound wave, increasing the sound insulation effect of the insulation board, and reducing the problem of noise entering the room.

2. By setting an anti-cracking mortar layer and an alkali-resistant glass fiber mesh layer, in order to prevent the insulation board from being affected by the external environment, which leads to the weakening of the structural strength of the insulation board, people use the internally filled anti-cracking mortar layer with high adhesion and flexibility to increase the flexibility of the insulation board. The alkali-resistant glass fiber mesh layer is wrapped inside the anti-cracking mortar layer, and a multi-layer type is used to reinforce the anti-cracking mortar layer. By combining with the anti-cracking mortar layer, a strong tensile strength and crack resistance are formed. The alkali-resistant glass fiber mesh layer can effectively absorb and disperse the stress generated by the building, prevent the formation and expansion of cracks, improve the building's crack resistance, and increase the stability and safety of the insulation board.

3. By setting a fire-retardant layer and a protective coating, in order to increase the flame retardancy and fire resistance of the insulation board, the fire-retardant layer can generate a fire barrier when a fire occurs, and slow down the spread of the fire by isolating the burning area and reducing heat transfer, which buys precious time for the evacuation of personnel, reduces the damage to the building structure caused by the fire, and prevents the fire from spreading to the insulation board, thereby improving the fire safety of the building. In addition, the protective coating provides protective properties for buildings and materials, including fire resistance, high temperature resistance and corrosion resistance. At the same time, the protective coating can also provide a certain moisture-proof effect to protect the insulation board from moisture and water. The above settings solve the problem of insufficient flame retardancy and fire resistance of the insulation board.

It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

Embodiment: As shown in Figure 1, a waterproof and moisture-proof composite insulation board includes: an insulation board body 1 is the main part of the entire insulation board, usually made of insulation material, has good insulation performance, can reduce heat conduction, and improve the insulation effect of the building; an adhesive layer 2 is used to fix the insulation board and enhance the stability of the structure, and it can use a special adhesive or adhesive to firmly attach the insulation board to the surface of the building; an arc-shaped protrusion 3 is usually located at the top and one side of the insulation board, and has an arc shape, which provides connection strength with the arc-shaped groove 4 and increases the stability of the structure; the arc-shaped groove 4 is usually located at the bottom and the other side of the insulation board, corresponding to the arc-shaped protrusion 3, which increases the stability of the entire structure.

As shown in Figure 2, it includes: a protective coating 6 which provides the insulation board with waterproof, fire-resistant and high-temperature resistant properties, and provides additional corrosion protection; expansion holes 7 allow the insulation board to be installed with holes reserved for expansion screws, which helps to maintain the structural integrity of the insulation board; a rubber ring 8 acts as a seal to prevent water and air from penetrating and increase the waterproof effect; a first support plate 9 increases the stability and structural strength of the insulation board; a rubber layer 10 provides the insulation board with waterproof properties and prevents moisture from penetrating; a fire-retardant layer 5 is used to provide additional fire protection, which can prevent the spread of flames, slow down the fire and protect the safety of buildings and personnel.

As shown in Figure 3, it includes: a second support plate 11 to provide additional support and structural strength, a sound-absorbing support frame 12 to provide noise reduction function, which can reduce noise propagation, absorb and reduce sounds close to the frequency by forming a resonant frequency of the object, a cavity 13 is arranged in the sound-absorbing support frame to form an isolation barrier, which can block the propagation path of sound and weaken the energy of sound waves by reflection, scattering and absorption of sound in the cavity, an anti-cracking mortar layer 14 has high adhesion and flexibility, can resist external environmental factors and changes in building structures, and reduce the generation and expansion of cracks, and an alkali-resistant glass fiber mesh layer 15 is connected to the inside of the anti-cracking mortar layer, and through combination with the anti-cracking mortar layer, the overall tensile strength and crack resistance are increased, thereby improving the stability and safety of the insulation board.

Working principle: First, for the problem of poor sound insulation performance, which leads to the spread of noise and affects people's use, during people's use, the object resonance frequency is formed through the sound-absorbing support frame 12, and the sound close to the object resonance frequency can be reduced, thereby increasing the sound insulation effect. The cavity 13 set inside the sound-absorbing support frame 12 can form an isolation barrier on the sound propagation path to block the propagation of sound. The sound will be reflected, scattered and absorbed many times in the cavity, thereby weakening the energy of the sound wave, thereby increasing the sound insulation effect of the insulation board and reducing the problem of noise entering the room. In order to prevent the insulation board from being affected by the external environment, resulting in the weakening of the structural strength of the insulation board, during people's use, the internally filled anti-cracking mortar layer 14 has high adhesion and flexibility, which makes the insulation board more flexible, and the alkali-resistant glass fiber mesh layer 15 is wrapped inside the anti-cracking mortar layer 14, and the multi-layer type is used to reinforce the anti-cracking mortar layer. The slurry layer is combined to form a whole with strong tensile strength and crack resistance. The alkali-resistant glass fiber mesh layer can effectively absorb and disperse the stress generated by the building, prevent the formation and expansion of cracks, improve the crack resistance of the building, and increase the stability and safety of the insulation board. In order to increase the flame retardant and fireproof properties of the insulation board, the fire retardant layer 5 is set to generate a fire barrier when a fire occurs, and the speed of the fire spread is slowed down by isolating the burning area and reducing heat transfer, which buys precious time for the evacuation of personnel, reduces the damage to the building structure by the fire, and prevents the fire from spreading to the insulation board, thereby improving the fire safety of the building. In addition, the protective coating 6 provides protective properties for buildings and materials, including fire resistance, high temperature resistance and corrosion resistance. At the same time, the protective coating can also provide a certain moisture-proof effect to protect the insulation board from moisture and water. The above settings solve the problem of insufficient flame retardancy and fireproofness of the insulation board.
