With the enhancement of people's awareness of fire protection and the strengthening of fire control by relevant government departments, the requirements for fireproof and heat insulation profiles are getting higher and higher. The frame materials used for traditional heat-insulating and fire-proof doors and windows are mainly plastic doors and windows or aluminum-plastic composite doors and windows, and then combined with insulating glass to form insulating doors and windows; due to the low strength of plastic or aluminum-plastic composite door and window profiles, they cannot meet the current high-strength, fire-proof and explosion-proof special requirements. glass requirements.

Subsequently, high-strength fireproof profiles appeared. By improving the structure of the profiles, they can play a role in fire prevention, and have certain heat insulation properties, reduce heat conduction indoors and outdoors, and are energy-saving and environmentally friendly. However, this profile only plays a certain role in insulation. Thermal action, if there is a fire, as the heating time increases and the temperature rises, its thermal insulation performance is limited, and the final profile is damaged, unable to support the glass. On the one hand, the collapse of the glass may cause casualties and property losses On the other hand, the collapse of fireproof glass can make the fire spread rapidly, and the consequences are extremely serious.

Therefore, in fireproof door and window profiles, if the frame profile is designed as an integral type, the heat conduction speed of the frame profile is too fast. In the case of indoor air conditioning in summer and indoor heating in winter, the temperature difference between indoor and outdoor is large, and too fast heat dissipation is not conducive to Energy saving. Therefore, the profile structure is designed to be hollow. The hollow structure has good thermal insulation performance, and can also prevent the profile from breaking and damaging quickly in the event of a fire, and cannot support the fire-resistant glass, causing heavy losses.
