Influence Law of Polyurea Coating Material on the Mechanical Properties of Agricultural Tractors
Agricultural tractors are often affected by severe corrosion in field operations,and polyurea coatings are widely used in the anti-corrosion protection of agricultural machinery.In this study,polyurea coating thickness,nano-reinforcer content and anti-corrosion agent content are selected as the influencing factors,and tensile strength and section shrinkage are used as evaluation indexes to carry out three-factor three-level orthogonal test.By analyzing the interaction and varia-tion law among the factors,the mechanism of polyurea coating on the mechanical properties of agricultural tractors was clarified,and the best combination of polyurea coating parameters was further explored:when the thickness of polyurea coating was 0.4 mm,the content of nano-reinforcer was 1.5％and the content of anti-corrosion agent was 15％,the me-chanical properties of polyurea coating on agricultural tractors were the best and met the production requirements.
