Abstract

The invention discloses an acid-resistant and alkali-resistant waterborne damping coating with a wide temperature range and high damping capacity, comprising, by weight, 30-65 parts of a waterborne emulsion, 15-45 parts of a filler, 10-35 parts of a flame retardant, 0.1-2 parts of fibers, 0-5 parts of a film-forming agent, 0.1-1.5 parts of a dispersing agent, 0.1-1.5 parts of a defoaming agent, 0-4 parts of an antifreeze agent, 0.2-3 parts of a thickening agent and 1-8 parts of a multifunctional aid. The acid-resistant and alkali-resistant waterborne damping coating with wide temperature region and high damping capacity has the advantages that the acid-resistant and alkali-resistant waterborne damping coating is high in damping performance, wide in damping temperature range and excellent in acid resistance and alkali resistance; loss factors of materials in the temperature range ranges from -30 DEG C to 50 DEG C reach 72 hours as shown by acid-resistant and alkali-resistant tests on the materials by the aid of 10% NaOH solution and 10% H2SO4 solution, and the acid-resistant and alkali-resistant waterborne damping coating is free of foaming, softening and sticking and excellent in acid resistance and alkali resistance.

Description
