Description
Technical Field
The invention relates to a hollow glass warm edge strip coated hot melt adhesive and a manufacturing method thereof.
Background
The hollow glass is formed by combining two or more glass plates, the glass plates are separated by an edge sealing system, and gas is filled in the middle of the glass plates. The glass plate may be a common plate glass, a tempered glass or a Low-E glass, which is selected depending on the place of use and the role of the insulating glass. The gas between the glass plates must be dry and may be air, argon or other special gas, with molecular sieves keeping the gas dry. Edge sealing systems are of a wide variety, mainly spacer bars (frames), sealants and molecular sieves. The spacer bars are arranged between the two layers of glass and play a role of separating the glass plates, and the peripheries of the two layers of glass are sealed by sealant so that the glass is bonded together and gas in the layers is prevented from overflowing. When two fluids having different temperatures are present on both sides of the hollow glass, the amount of heat passing through the central portion and the edge portion thereof is different. The heat passes through the glass plate in a mode of heat conduction and radiation, and the heat resistance is the same. The spaced gases primarily conduct heat and may also conduct convective heat transfer. The heat insulation capability of the hollow glass mainly comes from a sealed air layer, the heat conductivity coefficient of the air is 0.026W/m.K at the temperature of 20 ℃, and the heat conductivity coefficient of a common transparent glass plate is 0.76W/m.K, and the ratio of l: 29. in the air layer sealed by the hollow glass, the heat convection accounts for a smaller part and is basically in a heat conduction mode, so that the heat resistance of the hollow glass can be improved to a greater extent. At the edge of the hollow glass, it is the conductive heat transfer between the multiple flat walls, due to the close contact of the sealing system with the glass sheets. The heat conductivity coefficient of the spacer bar material has great influence on the thermal resistance, and the initially used aluminum spacer bar has large heat conductivity coefficient and small thermal resistance. For the hollow section, the air layer thickness is close to the spacer dimensions, so their thermal resistance ratio is also similar to the ratio of their thermal conductivity. The thermal conductivity of pure aluminum is 202W/mK, and the thermal conductivity of aluminum alloy is 130-150W/mK, so that the thermal resistance of the edge part is far smaller than that of the middle part. When different spacers are used, the temperature of the edge of the hollow glass can also change, and in winter, the thermal resistance of the peripheral part of the hollow glass of the building is small, and the temperature is obviously reduced. Because the indoor has certain humidity, the moisture in the air is condensed when contacting the glass plate with lower temperature, and the phenomenon of condensation and frosting is generated at the edge of the hollow glass, which not only influences the appearance, but also damages the sealing material.
In order to improve the phenomena of over-low thermal resistance and easy condensation and frosting of the peripheral parts of the hollow glass, research is focused on the thermal performance of the material and the shape of the spacing bars. The result shows that the material with lower heat conductivity coefficient is adopted to replace the traditional aluminum spacing bar, the peripheral temperature of the inner layer glass can be improved, and the dewing at the edge of the inner layer glass is avoided. Therefore, various materials with small heat conductivity coefficient and spacing strips (warm edge strips) with various shapes are developed in large quantity, and the warm edge strips are mainly formed by co-extrusion of PP and PVC plastics and stainless steel sheets coated with hot melt adhesive; therefore, the research and development of the hot melt adhesive coated by the warm edge strip is the technical key for manufacturing the warm edge strip.
