Novel high-temperature-resistant cold mounting material

Abstract

The invention relates to an ingredient designing and preparing method of a novel cold mounting material, in particular to a novel cold mounting material for metallographic specimen mounting. The coldmounting material is composed of, by mass, 5-8 parts of dental base acrylic resin liquid, 7-9 parts of dental base acrylic resin powder and 6-15 parts of aluminate cement. The preparation method includes: sufficiently mixing the dental base acrylic resin powder and the aluminate cement, and adding the dental base acrylic resin liquid. The cold mounting material prepared by the method is quick in curing, good in forming effect, high in hardness, wear resistance and deformation temperature and free of deformation after being formed below 200 DEG C.

Description

technical field [0001] The invention relates to the field of cold mounting materials for metallographic samples, and has the characteristics of high deformation resistance at high temperature and convenient operation. Background technique [0002] The invention aims to solve the problems that the deformation temperature of the current cold mounting material is low, and the samples well mounted by the cold mounting material cannot be heated at high temperature and high temperature mechanical property experiments cannot be performed. [0003] Inlaid metallographic sample preparation has the functions of sample fixation, sample support, and standardized samples. The inlaid samples need to continue to be subjected to high-temperature aging or mechanical performance experiments at high temperatures. Therefore, there are certain high temperature resistance requirements for the mosaic material. [0004] Cold mounting material is a mounting material for embedding samples at room te...
