【Abstract】 The characteristics of spray polyurea elastomer as a bulletproof impact resistant material were introduced, including plenty of hydrogen bond in the molecular structure, particularly sensitive to strain rate and excellent environmental performance. The research and application of polyurea in bullet-proof and anti-impact fields were summarized, the impact resistance mechanism of polyurea was discussed. The principles of formulation design and detection method of polyurea were pointed out.更多还原
