Abstract

The invention discloses a composite material for a large-diameter jacket head. The composite material comprises, by weight, 15-32 parts of TiN / Ti-B, 7-17 parts of Ti70Nb7.8Cu8.4Ni7.2Al6.6, 13-25 parts of Ti5Si3 / NiTi, 2-6 parts of Sm2O3, 1-5 parts of catalyst, 30-45 parts of chloroethylene / vinyl acetate and 28-41 parts of poly(n-butyl methacrylate). In this way, the composite material has higher corrosion resistance, high abrasion resistance, pressure resistance and high temperature resistance, and longer service life and is not prone to leakage or peeling.

Description

technical field [0001] The invention relates to the field of sealing heads, in particular to a composite material for large-diameter jacketed sealing heads. Background technique [0002] The head is an important part of the equipment. According to the different geometric shapes, it can be divided into spherical, elliptical, dish-shaped, spherical crown, conical shell and flat cover, among which spherical, elliptical, dish-shaped, and spherical Type heads are collectively referred to as convex heads. It is used in various container equipment, such as storage tanks, heat exchangers, towers, reactors, boilers and separation equipment, etc. It is connected with the cylinder to form the shell of the equipment. [0003] However, the materials currently used for large-diameter jacketed heads have poor corrosion resistance, easy leakage, easy peeling, poor wear resistance, and low pressure resistance. Contents of the invention [0004] The main technical problem to be solved by ...
