Abstract

The invention discloses a fire stopping ring core material and a preparation method and use thereof. The fire stopping ring core material consists of a core material solidifying agent, a flame-retarding agent, a carbonizing agent, a carbonization catalyst, a foaming agent, an expansible material, a reinforcing body, glue and other materials. The fire stopping ring core material disclosed by the invention has the advantages of environment protection, convenience and low cost; and at a certain temperature, the fire stopping ring core material can be used for quick plugging, the expansion factor of the fire stopping ring core material is high and the fire resistant time is long.

Description

technical field [0001] The invention relates to the technical field of engineering materials, in particular to a fire-stop ring core material and its preparation method and application. Background technique [0002] At present, there are many types of core materials for fire retardant rings on the market, and the quality is uneven, and there is a phenomenon of shoddy ones. There are some toxic substances in some core material formulas, which are harmful to the health of production workers and the production process is complicated. The molded core material takes a long time to cure, and the strength of the cured core material is small, and it is easy to break under the action of external force. Defects such as poor fire resistance and heat insulation effect. Contents of the invention [0003] The object of the present invention is to provide a core material of a fire retardant ring that is safe, environmentally friendly, low in cost, large in expansion coefficient and lon...
