Problems solved by technology

[0005] In aging, thermal aging is the most common aging phenomenon in the aging of polymer materials. The study of thermal aging is of great significance to the research of the properties of polymer materials. The existing thermal aging of polymer materials is usually performed in a thermal aging test box. However, the existing thermal aging test chamber has large test errors and low test efficiency, which affects the research on thermal aging of polymer materials.

Abstract

The invention provides a testing device for polymer material thermal aging and a testing method, and relates to the field of chemical engineering. The testing device comprises a box. A testing cavity and a preheating cavity are disposed in the box. The testing cavity is larger than the preheating cavity. The top of the preheating cavity is communicated with an annular gas delivery pipe. The annular gas delivery pipe winds at the bottom of the testing cavity, and is provided with a plurality of gas inlet holes communicated with the testing cavity. Each of the gas inlet holes is provided with a gas flowmeter. A first thermal insulating layer is adhered at the outer side of the testing cavity. The annular gas delivery pipe is disposed between the testing cavity and the first thermal insulating layer. The testing device is simple and efficient, and single-variable control for the thermal ageing testing device can be achieved, and therefore influences of temperature on thermal ageing can be researched.

Description

technical field [0001] The invention relates to the field of chemical testing, in particular to a polymer material thermal aging test equipment and a test method. Background technique [0002] Polymer materials are materials composed of compounds with relatively high molecular weight, including rubber, plastics, fibers, coatings, adhesives and polymer-based composite materials. Polymers are the form of life. All living organisms can be regarded as a collection of macromolecules. [0003] Polymer materials are divided into natural polymer materials and synthetic polymer materials according to their sources. Natural polymers are polymer substances that exist in animals, plants and organisms, and can be divided into natural fibers, natural resins, natural rubber, animal glue, etc. Synthetic polymer materials mainly refer to the three major synthetic materials of plastics, synthetic rubber and synthetic fibers, and also include adhesives, coatings and various functional polyme...
