AI Technical Summary
Existing fireproof and sound-absorbing coatings cannot achieve a balance between density and porosity, resulting in brittle and easily cracked coatings. Furthermore, the application process is complex, making it difficult to achieve a combination of fireproofing, sound absorption, and elasticity.
A multifunctional construct composition is adopted, which integrates a ceramic flame-retardant skeleton, in-situ encapsulated phase change heat storage microcapsules, multi-scale sound-absorbing fillers and SEBS-g-MAH elastic toughening body. Through a temperature and time synergistic process of mechanical air entrainment and static defoaming, a gradient structure of a dense surface pre-skin layer and a porous bottom sound-absorbing core layer is spontaneously constructed.
It achieves a three-in-one effect of fire resistance, sound absorption, and elasticity, solving the problem that traditional coatings cannot simultaneously achieve both fire resistance and density, and sound absorption and porosity. It provides a solution that can form a gradient structure with a single coating without the need for precise temperature control equipment.
