Method, device and electronic equipment for determining storage life of resin adhesive

Abstract

The invention relates to a method, device and electronic equipment for determining the storage life of a resin-type adhesive. By improving the Arrhenius model, the quadratic relationship between the logarithm of the accelerated life of the resin-type adhesive and the reciprocal of the temperature is established, thereby obtaining the resin-type adhesive. The relationship between the accelerated life of the adhesive and the temperature is obtained to obtain its actual storage life at a normal storage temperature. This method has a higher degree of fitting for the life and temperature, and the storage life of the obtained epoxy resin adhesive is also more accurate; the present invention Expand the nonlinear relationship between temperature and accelerated life, and use the improved model for data fitting, which solves the problem that the traditional Arrhenius cannot reproduce the relationship between the high-order term of temperature and life, and reduces the life estimation error; The invention updates the calculation at different temperatures. Compared with the existing methods, the present invention is not only applicable to the life estimation of resin adhesives at low temperature, but also applicable to the situation of high temperature life estimation.

Description

technical field [0001] The invention relates to a method, device and electronic equipment for determining the storage life of a resin adhesive, in particular to a method, device and electronic equipment for determining the storage life of a thermosetting resin adhesive, belonging to the technical field of storage life and accelerated testing of resin adhesives. Background technique [0002] Resin-based adhesives have a long history, especially thermosetting resin-based adhesives (such as epoxy resin adhesives), which used natural products as adhesives in the early days. With the development of science and technology, especially the development of the aerospace industry and the development of synthetic polymer materials, Synthetic adhesives have gradually been widely used in structural connection, equipment repair and sealing. As a kind of adhesive widely used in aviation, aerospace and other fields, resin adhesive has extensive and in-depth performance assessment to ensure t...

Problems solved by technology

[0007] Using the Arrhenius model to establish the relationship between accelerated life and temperature, it can be seen that the relationship between the logarithm of the accelerated life and the reciprocal of the temperature is a linear function relationship, but in the accelerated life test data of epoxy resin adhesives, it can be seen that the acceleration The logarithm of the life and the reciprocal of the temperature are not a simple quadratic relationship, so the traditional Arrhenius model cannot well establish the relationship between the accelerated life of the epoxy resin adhesive and the temperature, so that the exact value of the epoxy resin adhesive cannot be obtained.
