Description

A kind of phenolic composite fireproof insulation board for building

technical field

The utility model relates to the field of building boards, and in particular provides a phenolic composite fire-proof and heat-preservation board for buildings, which has dual functions of fire prevention and heat preservation.

Background technique

In view of the frequent occurrence of fire accidents caused by building insulation materials, on September 25, 2009, the Ministry of Public Security and the Ministry of Housing and Urban-Rural Construction jointly issued the "Interim Regulations on Fire Protection of Civil Building External Thermal Specific requirements are put forward for the combustion grade of the material and the structure of the fire barrier. At present, the inorganic fireproof barriers used in buildings are made of foamed cement and foamed ceramics. Although they can block fires, their thermal insulation effects are not good. In addition to their weight, they increase the load on the walls and bring inconvenience to the construction.

Therefore, people are badly in need of finding a kind of not only fireproof, but also the building plate of heat preservation.

Utility model content

The purpose of the utility model is to provide a special phenolic composite fireproof and heat preservation board for external wall insulation, so as to solve the problem of poor heat insulation effect of the existing fireproof board.

The utility model provides a phenolic composite fireproof and thermal insulation board for construction, which is characterized in that: the fireproof thermal insulation board uses a hard phenolic foam board as a core material 1, and the six sides of the core material 1 are sequentially covered with polymer Adhesive mortar layer 2, alkali-resistant glass fiber mesh reinforcement layer 3 and polymer plastering mortar layer 4, a layer of material 5 is fixed on the surface of polymer plastering mortar layer 4, wherein the surface material 5 is fiber-reinforced silicon Calcium acid board or fiber reinforced cement board.

The phenolic composite fire-proof insulation board for buildings provided by the utility model can not only effectively prevent flames from spreading, but also has outstanding heat insulation and energy-saving effects. Detailed structure, detailed structure under the pick-up plate, detailed structure of door and window tops and under the pick-up plate, detailed structure at the junction of the roof and the outer wall, and detailed structure of the roof opening, etc.

When a building catches fire, the fireproof insulation board provided by the utility model can effectively form an isolation zone at the door and window to prevent the flame from spreading, preventing the fire from spreading to the room through the outer wall, door and window. At the same time, due to its own flame retardant properties, it can block the development of fire and prevent the spread of flames.

The phenolic composite fireproof insulation board for buildings provided by the utility model has the following advantages:

1. The phenolic composite fire-proof insulation board for construction in the utility model uses hard phenolic foam board as the core material, which mainly plays the role of heat preservation, and the hard phenolic foam board is compared with polystyrene, polyurethane foam and other insulation materials. It has high flame retardancy and heat resistance, which makes the insulation board not easy to burn, and installing it on the outer wall of the building improves the fire protection level of the building; at the same time, because the phenolic foam board does not produce thick smoke and Toxic and harmful gases will not cause harm to the human body due to the burning of insulation materials, and have the characteristics of high safety;

2. The utility model adopts phenolic foam as thermal insulation material. Since the phenolic foam board has the characteristics of light weight, low thermal conductivity, high thermal insulation efficiency and stable performance, on the one hand, it can reduce the load on the outer wall of the building to the greatest extent. On the other hand, it can significantly reduce the energy consumption of buildings, save energy and improve energy saving efficiency;

3. The polymer bonding mortar added to the phenolic composite fireproof and heat preservation board in the utility model is used as a high molecular polymer cement-based prefabricated mix. It has excellent adhesion, good enhanced sagging resistance, water retention, water resistance, aging resistance and operability. It is used for pasting core materials and surface materials. It is easy to construct, non-toxic and polluted, and has a strong combination. Durability, anti-crack, anti-aging, waterproof and other characteristics;

4. The special grid cloth for external wall insulation added to the phenolic composite fireproof and thermal insulation board in this utility model is based on medium-alkali or non-alkali glass fiber woven fabric, and is processed by alkali-resistant coating. The product has high strength and good alkali resistance, and plays an important structural role in the insulation system, mainly preventing cracks. Due to its excellent anti-acid, alkali and other chemical substances corrosion performance and high tensile strength in warp and weft direction, it can make the stress on the external wall thermal insulation system evenly distributed, and can avoid the entire thermal insulation caused by the collision and extrusion of external impact. The deformation of the structure makes the insulation layer have high impact strength, and is easy to construct and quality control, and plays the role of "soft steel bar" in the insulation system;

5. The polymer anti-crack mortar added to the phenolic composite fireproof and heat preservation board in this utility model is a kind of special polymer and related additives and anti-crack substances. In the construction, the alkali-resistant mesh cloth is compositely inlaid to form a protective layer for the outer layer of thermal insulation. It is impact-resistant, crack-resistant, wind-pressure-resistant, waterproof, not hollow, and not peeling off. It especially solves the problem of cracks caused by the large temperature difference coefficient between the inside and outside of the insulation layer and the expansion and contraction of the joints between the plates, which improves the quality of the system and ensures the protective layer. not crack;

6. The surface material of the phenolic composite fireproof insulation board in this utility model is made of siliceous material and calcareous material with an appropriate amount of reinforcing material added, and undergoes processes such as pulping, molding, autoclaving, drying, sanding and post-processing. , and made of a new type of inorganic non-metallic board, which has the advantages of light weight, high strength, fireproof and heat insulation (heat insulation coefficient is less than 0.4), durable, low dry shrinkage, good processing performance, and easy surface decoration;

7. The utility model has excellent comprehensive performance. While not reducing the effect of heat insulation and energy saving, it also isolates the fire source area and controls the fire loss to the minimum;

8. The fireproof insulation board provided by the utility model is constructed with cement and the building wall as a whole. It is easy to be integrated with the base wall and can also be pasted on the wall. The construction efficiency is high and the cost is low.
