Modification method for improving shape memory performance of gutta-percha rubber

Abstract

The invention provides a modification method for improving the shape memory performance of gutta-percha rubber and belongs to the technical field of material modification. Through the modification method, the problems that an existing gutta-percha rubber modification method is single, the shape memory performance is poor, the crystallization temperature is not matched with the asphalt pavement using temperature range and the gutta-percha rubber is low in utilization rate and can hardly improve the shape memory performance and the self-repairing function of an asphalt pavement when used for modifying asphalt and reduce asphalt pavement cracks or the crack width are solved. The modification method comprises the steps of firstly, preparing the modified gutta-percha rubber with the shape memory performance; secondly, conducting mold pressing on the gutta-percha rubber subjected to sufficient reaction and giving the shape memory performance to the gutta-percha rubber; and finally, carryingout a performance study through related instruments to determine that the modified gutta-percha rubber has the optimum shape memory performance. Through the modified gutta-percha rubber prepared through the method, the asphalt can be modified, and the asphalt pavement has the shape memory performance. Meanwhile, the gutta-percha rubber is modified, the modification manner of the gutta-percha rubber is enriched, and the utilization rate of the gutta-percha rubber is improved.

Description

technical field [0001] The invention relates to a modification method for improving the shape memory performance of eucommia gum, belonging to the technical field of material modification. Background technique [0002] In recent years, great breakthroughs have been made in the research on the application of eucommia gum. Since its molecular chain structure has three characteristics of double bond vulcanization, orderliness, and chain flexibility, it has great potential for development. Eucommia gum is divided into natural Eucommia gum (EUG) and synthetic Eucommia gum (TPI). EUG is mainly derived from the Eucommia tree, and China has more than 95% of the Eucommia tree resources in the world. Domestic TPI mainly comes from individual new material companies, which have 10,000-ton-level trans-isoprene rubber industrial production equipment, which can provide a large number of new high-quality raw materials for various researches. In the 1980s, Eucommia gum elastomer was prepare...
