Raw materials of door and window sealant

Door and window sealants are welcomed and supported by consumers in our lives. Do you know what the raw materials of our door and window sealants are?

Door and window sealant is ordinary glass glue, generally transparent, white and black. The fabric is rarer, and the weather-resistant rubber is usually white or black with an intricate texture. Structural adhesives are generally black, and there are also two-component structural adhesives, which are the same in appearance as weather-resistant rubber. It is often used in combination in the market. Structural adhesives focus on strength and meet certain tensile strength and shear strength. Weather-resistant adhesives focus on aging resistance such as ozone, oxygen, weak acid, and ultraviolet rays.

The raw materials of sealant include silicone, polyurethane, polysulfide, acrylic acid, butyl, asphalt and oil-based resin modified products, etc. Among them, silicone, polysulfide urethane and polyurethane three room temperature curing elastic sealants are widely used in my country, especially It is a silicone sealant product. Due to its special molecular structure, silicone sealant has the characteristics of both inorganic and organic polymers.

Silicone rubber is stable and has excellent UV resistance, ozone resistance, weather resistance, temperature resistance and the characteristics of single-liquid and double-liquid applications. At the same time, products with different performance requirements can be prepared according to building needs, especially in the structure of shutter glass curtain wall It has replaced other materials in bonding applications. Moreover, at present, silicone-based building sealant products account for more than 60% of my country's building sealant consumption.

How to choose door and window sealant

Introduction to silicone glass glue manufacturers, door and window sealants play a very important role in our lives, but do you know the correct way to choose our door and window sealants?

First, the standard of door and window sealant is briefly introduced. When choosing a sealant product that meets the corresponding standards, the user should also consider the actual use and make the correct choice. At the same time, use high-quality sealant products whenever possible, and never use mineral oil-filled silicone sealants. Through test data and cases, the hazards of some mineral oil-filled silicone sealants on the market are analyzed and expounded, and the method of identifying oil-extended silicone adhesives is introduced.

With the continuous improvement of the quality of life, people have clear requirements for the quality and performance of houses, and more and more attention is paid to the energy-saving performance, safety performance, sound insulation and noise reduction, sun protection, comfort and durability of building doors and windows. When consumers buy building door and window products, they not only require beautiful products, but also pay more and more attention to excellent performance. Although sealant is only an auxiliary material in the manufacturing process of doors and windows, accounting for a small proportion of the cost, it plays a very important role in the performance of doors and windows, especially in terms of water tightness, air tightness, thermal insulation and sound insulation.

If the sealant has quality problems, it will lead to water leakage, air leakage and other problems, which will seriously affect the air tightness and water tightness of doors and windows; therefore, special attention should be paid to the correct selection of sealant, and it should not be sloppy, so as not to fail the application of the sealant. , the performance of doors and windows does not meet the expected requirements.
