Problems solved by technology

[0003] In order to avoid leakage during the measurement process, the electronic components in the measurement device must be potted with sealant. At present, epoxy resin is mostly used as the main component for the sealing of electronic components. The epoxy resin used for this purpose is usually Acid anhydrides are used as curing agents, and the curing reaction generally needs to be carried out above 100°C, which consumes more energy; although the cured product has good light transmittance and physical and chemical properties, it has high hardness, poor flexibility, and low elongation at break , the packaged electronic components cannot be bent and installed at will, and once the sealing surface is damaged, it will be difficult to repair

Abstract

The invention belongs to the technical field of epoxy resin sealants, and particularly relates to a sealant for a water content measuring device. The sealant is composed of a component A and a component B. The component A comprises the following components in parts by weight: 40-80 parts of modified epoxy resin, 10-40 parts of polytetrafluoroethylene micropowder, 2-8 parts of a diluent, 1-10 partsof a dispersing agent and 0.05-0.5 part of a defoaming agent. The component B comprises the following components in parts by weight: 5-15 parts of an epoxy curing agent, 1-7 parts of a silane coupling agent, 1-5 parts of a dehydrating agent and 0.5-2 parts of an ultraviolet absorbent. According to the sealant, defects in the prior art are overcome, potting and curing can be performed under a roomtemperature condition, and the sealant is high in bonding strength, excellent in aging resistance, cracking resistance and flexibility and capable of being well applied to potting electronic components.

Description

technical field [0001] The invention belongs to the technical field of epoxy resin sealants, and in particular relates to a sealant for water content measuring devices. Background technique [0002] The water content of crude oil is the main factor that directly affects the extraction, dehydration, gathering and transportation, metering, sales, and refining of crude oil. Therefore, it is required to detect the water content of crude oil in the process of crude oil production, storage and transportation. On-line detection of water content in crude oil is of great significance for determining the water and oil production layers of oil wells, estimating crude oil production, and predicting the development life of oil wells. At the same time, the accurate and timely online detection of the water content of crude oil can reflect the working status of the oil well in real time, which plays an important role in reducing energy consumption and cost for the management department and ...
