Problems solved by technology

[0004] The prior art described above has the following deficiencies: 1. Rubber-plastic modified sealing strips, PVC sealing strips, have low aging resistance, and are easily brittle and cracked in a short period of time through sunlight and high-temperature environments, and are water-tight and air-tight. Sexuality drops sharply, and it will release harmful gas to pollute the environment
2. Although EPDM strips and other elastomer strips have good elasticity, they have poor air-tightness and water-tightness, poor followability, and are not resistant to aging. In order to maintain good elasticity, a large amount of plasticizer needs to be added, and it will precipitate out after a long time , easy to pollute the environment
3. Although the use of silicone structural adhesive seals has good elasticity and bonding fastness, if all of them are used for sealing, the appearance will be untidy, and the water-tightness and air-tightness of silicone structural adhesives are poor, the construction process is complicated, and the cost is high. low efficiency
4. Although the EVA tape or PE foam tape coated with pressure-sensitive adhesive is convenient and clean, it only plays the role of fixing the glass and the frame, and has no sealing effect
This kind of sealing strip has good sealing and elasticity, but its temperature resistance is poor, and its applicability is affected

Description

technical field [0001] The invention relates to the technical field of building sealant strips, in particular to a sealant strip for building curtain walls. Background technique [0002] Doors, windows and curtain walls are mainly composed of aluminum alloy or steel-plastic structure, insulating glass and low-E glass or ordinary glass, and the sealing of doors, windows and curtain wall frames and glass accounts for a large proportion (15%) of the entire building energy saving. In the stage of sealing doors, windows and curtain walls, structural adhesives and sealing strips are mainly used together or alone, which puts forward high requirements on the tightness and aging resistance of sealants and strips, because poor sealing directly affects Building energy-saving technical indicators, and poor aging resistance will directly affect the cost of building energy-saving use, because the service life of doors, windows and curtain walls is generally required to be more than 20 yea...
