Abstract

The epoxy resin modified with polyurethane was used as matrix resin forpreparation of anti-rolling and wear-resistant coatings applied on heavy loading decks ofships,and the performance of which was optimized by adding tri-functional epoxy resin,wear resistant fillings,mica powder,abrasive aggregates and so on. The technical route of developing anti-rolling and wear-resistant coatings was based on the impact force and shearstress that the coatings suffered when the heavy loaded pedrail vehicles were traveling. Theimpact force and shear stress of coatings suffered at the working condition of turning of heavy-duty caterpillar were investigated through analysis of virtual prototype with finite elementsimulation,based on the elastic modulus,yield strength and tensile strength of the preparedcoatings. The formulation of coatings was analyzed and confirmed concerning three aspects ofreinforcing resin,wear resistant fillings and abrasive aggregates. Then the compressive strength,abrasion performance,curing time,impact resistance and saline immersion resistanceof the prepared coatings were determined. The results indicated that the wear loss and compressive strength of coatings were 24 mg and 117 MPa respectively. The coatings passedthe falling ball impact and tolerated seawater immersion of 180 d. In conclusion,the preparedcoatings possessed excellent anti-rolling and wear-resistance and could be applied to protectthe heavy loaded decks of ships.
