Aiming at the high temperature, high speed, high precision and high surface quality of the copper belt cold rolling, the purpose of this paper is to develop a new type of lubricant for cold rolled copper belt.

The component of the developed oil was determined based on the physical and chemical properties of the base oil and the tribological properties, the oxidation resistance properties, the rust resistance properties, the anti-foam properties, the demulsibility and the other properties of the additives. The orthogonal experiment method was used to determine the optimum adding amount of the additives; finally, the developed oil formulation was determined.

The physical and chemical experiment results show that the developed oil has a good performance of oil film bearing capacity and oxidation resistance. The simulation of rolling experiment found that the developed oil can significantly reduce rolling pressure and effectively reduce the friction in the process of rolling.

The experimental results show that the developed oil has excellent performance and can meet the requirement of lubrication in the process of cold rolling copper belt.

Purpose: This study explores the growing significance of environmentalism and sustainability in the contemporary business landscape. Focussing on aligning industries with evolving consumer expectations, the research seeks to understand the awareness surrounding environmental conservation, sustainable development, and the adoption of an environmentally conscious lifestyle.

Need for the study: With environmental consciousness on the rise, understanding the initiatives taken by organisations and the utilisation of digital platforms for environmental advocacy becomes crucial. The study addresses the need to unwind the cultural shift towards sustainability and assess the effectiveness of green marketing practices in the digital age.

Methodology: A triangulation approach is employed, integrating secondary data from literature research with information from company reports and databases. The literature survey provides extensive insights into green marketing practices, forming the basis for an in-depth analysis. The comparative analysis and integration of findings from both sources aim to draw a comprehensive picture, identifying areas of agreement and disagreement.

Findings: The study provides robust evidence supporting the effectiveness of green marketing practices in the digital age. Convergence between academic literature and real-world corporate practices underscores the consistency in approaches adopted by companies in leveraging digital technology to advance environmental sustainability.

Practical implications: The findings suggest that theory and practice converge on various aspects of green marketing, indicating its profound impact on culture, behaviours, and strategies. This research informs businesses and policymakers about the tangible benefits and shared responsibility of incorporating green practices in corporate strategies, fostering a sustainable future.
