Abstract

The invention discloses a modified PVC (Polyvinyl Chloride) cable material of a high-temperature high-moisture resistant sensor and a preparation method of the modified PVC cable material. The PVC cable material is mainly prepared from the following raw materials in parts by weight: 80-120 parts of a PVC resin, 30-60 parts of a thermal-resistant plasticizer, 3-8 parts of a calcium-zinc stabilizer,5-10 parts of coarse whiting, 3-9 parts of calcined kaolin, 3-6 parts of a composite flame retardant, 0.5-2 parts of an acrylic resin and 0.2-1 part of a comprehensive internal and external lubricant, wherein the PVC resin is polyvinyl chloride of which the polymerization degree is within 1800-2000; the thermal-resistant plasticizer is a trioctyl trimellitate plasticizer; and the composite flameretardant is prepared from antimonous oxide and magnesium hydrate through compounding. The modified PVC cable material is capable of meeting national standards of China and customer use requirements,also has the advantages of low cost, high production efficiency and good stability, can be processed into components normally, and is applicable to wide popularization and application.

Description

technical field [0001] The invention belongs to the technical field of PVC cable material preparation, and in particular relates to a modified PVC cable material for a high-temperature and high-humidity sensor and a preparation method thereof. Background technique [0002] With the advancement of science and technology, temperature sensors are used more and more widely, which are mainly used in the following aspects: (1) for temperature detection of automobile batteries, engines, transmission mechanisms, air conditioners and internal / external environments, as well as oil and Gas liquid level detection, (2) used to monitor the temperature of aircraft, satellites, ground radars, manned orbiters and deep space sounding rockets. As a key component of the NTC temperature sensor, the sensor cable has an important impact on the performance and accuracy of the NTC temperature sensor. More than 90% of the domestic sensor cables can only meet the unilateral requirements of high tempe...
