Abstract

The invention provides a test method of a thermoplastic separation strip and outer adhesive bonding performance. The method comprises the following steps of providing a test specimen; stretching the test specimen under the standard condition; detecting the damage area of the bonding surface of the test specimen after the stretching; performing stretching on the test specimen after the aging underthe conditions of high and low temperature exchange and long-time high temperature; detecting the damage area of the bonding surface of the test specimen after the stretching. The result that the damage area of the bonding surface in the detection does not exceed 5 percent shows that the bonding performance of the thermoplastic separation strip and the outer adhesive meets the requirement. Throughthe test method provided by the embodiment of the invention, the bonding effect of the thermal plastic warm edge separation strip and the outer adhesive can be accurately judged; the phenomenon of adhesive strip falling of the thermoplastic warm edge hollow glass in the use process and the influence on the service life and the attractive appearance can be reduced.

Description

technical field [0001] The invention relates to a test method for the bonding performance of a sealant, in particular to a test method for the bonding performance of a thermoplastic spacer and an outer sealant. Background technique [0002] As a new type of energy-saving material, hollow glass has achieved long-term development since it was introduced into my country in the 1980s, and is widely used in many fields such as public buildings and civil buildings. At present, among the more than 40 billion square meters of existing buildings in our country, more than 90% are high energy consumption buildings. In these high-energy-consumption buildings, the energy consumption of doors and windows is 45% to 50%, accounting for 20% of the total energy consumption of the society. Therefore, enhancing the thermal insulation performance of doors and windows and reducing the energy consumption of doors and windows is an important part of improving the indoor thermal environment and imp...
