A Modification Method for Improving the Shape Memory Performance of Eucommia Gum

Abstract

The invention is a modification method for improving the shape memory performance of eucommia gum, belongs to the technical field of material modification, and solves the problems of single modification method of eucommia gum at present, poor shape memory performance, mismatch of crystallization temperature with the service temperature range of asphalt pavement, leading to problems of eucommia ulmoides The utilization rate of glue is low, and it is difficult to improve the shape memory performance and self-healing function of asphalt pavement when used in modified asphalt, and reduce the problem of asphalt pavement cracks or crack width. The present invention firstly prepares modified eucommia gum with shape memory performance, then molds the eucommia gum after sufficient reaction and imparts shape memory performance, and finally uses relevant instruments to conduct performance research to determine that the modified eucommia gum has the best shape memory performance formula . The modified eucommia gum prepared by the invention can modify the asphalt and make the asphalt pavement have shape memory performance. At the same time, the modification of eucommia glue enriches the modification methods of eucommia glue and improves the utilization rate of eucommia glue.

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...

Problems solved by technology

[0010] The purpose of the present invention is to provide a modification method for improving the shape memory performance of eucommia gum, which solves the problem that the existing modification method of eucommia gum is single, the shape memory performance after modification is poor, and the crystallization temperature does not match the temperature range of the asphalt pavement, which leads to the utilization of eucommia gum. It is difficult to improve the shape memory performance and self-healing function of asphalt pavement, reduce the cracks of asphalt pavement or reduce the width of cracks when used in modified asphalt

[0012] In order to solve the current modification method of eucommia gum, the shape memory performance after modification is poor, and the crystallization temperature does not match the temperature range of asphalt pavement, resulting in low utilization rate of eucommia gum, and it is difficult to improve the shape memory performance of asphalt pavement and Self-healing features, problems reducing asphalt pavement cracks or reducing crack width
