Application of Castor Oil-Based Potassium Metaborate Extreme Pressure Agent BMEP-20 in Fully Synthetic Cutting Fluids

In today's cutting fluid market, with increasing environmental awareness, there is a growing demand for green and environmentally friendly performance of cutting fluids. The use of biodegradable vegetable oils to replace mineral oils as the base oil for water-soluble cutting fluids has become a trend. The method of using modified vegetable oils containing extreme pressure agents to replace toxic additives in water-based cutting fluids is gradually becoming a research and development direction for scientists and technicians. With the overall advancement of mechanical industry technology, machine tool cutting speeds are faster, cutting loads are greater, and cutting temperatures are higher. At the same time, new processes continue to emerge to adapt to the processing of new materials, all of which require new high-performance cutting fluids to meet processing requirements. Additionally, according to occupational health and environmental protection requirements, cutting fluids should not contain substances harmful to human health and the ecological environment. The castor oil-based potassium metaborate extreme pressure agent developed by Zibo Pengxin Chemical Technology Co., Ltd. is increasingly widely used in fully synthetic water-based cutting fluids. The development of high-performance, environmentally friendly, biodegradable, and long-lasting cutting fluid extreme pressure agents, along with methods to extend the service life of cutting fluids, helps reduce the discharge of cutting fluid waste.

The castor oil-based potassium metaborate extreme pressure agent developed by Zibo Pengxin Chemical Technology Co., Ltd. directly synthesizes high-content boron-based extreme pressure agent potassium metaborate BMEP-20 (BM stands for castor oil base, EP is the abbreviation for extreme pressure agent, and 20 represents the content of potassium metaborate) while modifying castor oil for water solubility. This product can form an efficient extreme pressure lubricating film on the surface of friction pairs under extreme conditions such as high temperature, high pressure, and heavy loads. It has high hard water solubility, can be formulated into a light yellow transparent aqueous solution, is resistant to high-temperature carbonization, and is biodegradable. The slight toxicity in castor oil can inhibit the growth of bacteria and mosquitoes but is safe and harmless to humans.

Introduction to Boron-Based Extreme Pressure Agent Potassium Metaborate

Potassium metaborate is environmentally friendly and does not contain harmful elements such as sulfur, phosphorus, or chlorine, addressing the issue of traditional extreme pressure agents polluting the environment. It solves the problem of workers frequently being exposed to metalworking fluids during metal processing, which can cause skin irritation, redness, itching, contact dermatitis, and peeling. It is an ideal extreme pressure additive for formulating synthetic metal cutting fluids that are safe, environmentally friendly, non-toxic, and high-performance. The castor oil-based potassium metaborate extreme pressure agent developed by Zibo Pengxin Chemical Technology Co., Ltd. is water-soluble, eliminating the need to consider particle size, dispersing agents, or concerns about precipitation or crystallization in aqueous solutions. It offers good stability and is simple and convenient to use and store.
