摘要
Abstract
Polyvinylpyrrolidone(PVP)aqueous solution and trehalose were employed as composite adhesives,mica powder was selected as the matrix material,and silicon carbide and hollow glass microspheres were chosen as modifying fillers,whereby a high-temperature-resistant water-soluble core mold material suitable for composite molding was successfully prepared.The effects of curing temperature and adhesive formulation ratio on the mechanical and water-soluble properties of the core mold material were systematically investigated,and the micro-morphology,composition,thermal resistance,and thermal expansion behavior of the water-soluble core mold were characterized and analyzed.The results indicated that when the curing temperature reached 160℃and the mass fraction of trehalose in the adhesive was 60%,the core mold material exhibited optimal comprehensive performance,with its flexural strength and compressive strength reaching 17.34 MPa and 12.43 MPa,respectively,and the dissolution rate attaining 1.23 g/min.Below 420℃,this water-soluble core mold material demonstrated favorable thermal stability,and its coefficient of thermal expansion ranged between-3.10×10-5℃-1 and 1.02×10-5℃-1 within the temperature interval of 25～250℃.关键词
