Description

technical field [0001] The invention relates to the technical field of fireproof materials, in particular to a fireproof elastic sealant. Background technique [0002] Fireproof elastic sealant is mainly used for the fireproof isolation of various openings formed when cables, air pipes, oil pipes, air pipes, etc. pass through walls and floors, and cable trays. Due to the requirements of special environments, fireproof sealants must have high performance such as radiation resistance, ozone resistance, cold resistance, aging resistance, high temperature resistance, and flame retardancy. Existing sealants cannot have special properties such as flame retardancy, radiation resistance, ozone resistance, and water resistance at the same time. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a fireproof elastic sealant with excellent water resistance and radiation resistance, cold resistance, ...
