Abstract

The invention provides a low flame spread damping coating. The low flame spread damping coating is composed of a damping layer and a restraint layer, wherein the damping layer is attached to a substrate, the restraint layer is attached to the damping layer, and the damping layer is formed by mixing components A and B which are identical in mass; the component A is synthesized by reacting polyether 2000, polyether 3050 and TDI; the component B is composed of the following substances: modified hydrated alumina, glycol, dibutyl ester, Moca, mica powder and chrome green; the restraint layer is formed by mixing a first component with a second component in the mass ratio of (15-18): 1, wherein the first component comprises epoxy resin, dibutyl ester, modified hydrated alumina and iron oxide brown; the second component comprises polyamide and triethylene tetramine. The low flame spread damping coating has a vibration and noise reduction effect, is high in composite loss factor, wide in damping temperature range, curable through reaction at room temperature, convenient for construction, even and adjustable in thickness and good in adhesion, and does not crack or peel.

Description

technical field [0001] The invention provides a low-flame-spread coating, in particular to a coating with excellent comprehensive properties such as damping, vibration reduction, sound insulation, sealing, and heat insulation, and belongs to the field of coatings. Background technique [0002] When the machine is running, friction will be generated in many parts, and the friction will bring noise and heat, which will not only cause noise pollution, but also cause the machine to wear and tear due to the heat generated. The damping coating is prepared by adding a proper amount of fillers and auxiliary materials to a polymer resin. It is a special coating that can be coated on the surface of various metal plate structures. It has vibration reduction, heat insulation and certain sealing properties. It can be widely used. It is used for vibration reduction of aircraft, ships, vehicles and various machinery. Since the paint can be directly sprayed on the surface of the structure,...
