Problems solved by technology

[0006] The temperature sensor is used in an environment with a large temperature range. The measurement material is not limited to a neutral environment, and may be used in an acid-base environment, so it is prone to cracking, which affects the accuracy of measurement data and the service life of the sensor. , therefore, it is necessary to develop an epoxy resin product with strong chemical resistance and not easy to crack

Abstract

The invention relates to a manufacturing process of epoxy resin for temperature transducers. The process includes: by weight part, adding polyurethane modified epoxy resin, bisphenol A epoxy acrylate,glycidyl methacrylate, vinyltri(dimethylsilyloxy)silane, metal nickel chelate agarose gel 6FF, (2-methane acylphenyl)(1R, 2S)-1-amino-2-vinylcyclopropane methyl formate4-methylbenzenesulfonate into areaction kettle, mixing the substances evenly, and carrying out reaction at 65-90DEG for 4-10h, thus obtaining the epoxy resin product.

Description

technical field [0001] The invention relates to a manufacturing process of epoxy resin, in particular to a manufacturing process of epoxy resin for a temperature sensor. Background technique [0002] A temperature transducer is a sensor that can sense temperature and convert it into a usable output signal. The temperature sensor is the core part of the temperature measuring instrument, and there are many varieties. According to the measurement method, it can be divided into two categories: contact type and non-contact type. According to the characteristics of sensor materials and electronic components, it can be divided into two types: thermal resistance and thermocouple. [0003] Epoxy resin can cross-link with various types of curing agents to form an insoluble polymer with a three-way network structure. All polymer compounds containing epoxy groups in their molecular structure are collectively referred to as epoxy resins. The cured epoxy resin has good physical and che...
