Friction Materials Boron-Modified Phenolic Resin Tung Oil Microwave Synthesis Research

Microwave technology is in the 1980s with the emergence of a new organic synthesis technology, microwave as an effective heat source is widely used in chemical synthesis of various fields, especially in the field of synthetic organic chemistry is developing rapidly. Usually in the traditional heating conditions require a longer time to return to complete the reaction in the microwave for easy and quick to complete. Compared with conventional heating, microwave radiation under the uniform heating of organic reaction system, increasing risk of collisions between molecules, can significantly shorten the process by the use of time and increase yield response, simple operation, therefore, microwave radiation technology used in industrialized Production prospects are broad, is of great significance.Phenolic resin is a first discovered and access to wider use of synthetic resin, the raw materials can be used as a friction material, adhesive, paint, and so on. But with the rapid development of modern industry, a number of areas on the heat-resistant resin and flexibility of a higher demand, therefore, the phenolic resin modified, while improving its heat resistance and flexibility are high-performance Phenolic resin direction for the development of boron phenolic resin than phenolic resin is more excellent heat resistance and mechanical properties, tung oil molecules embedded in a long chain of carbon phenolic resin may raise the oil-soluble and toughness, we in the preparatory work On the basis of boron PF / Tong phenolic material at the same time modified. In this paper, and boron-phenolic resin modified phenolic resin synthesis of traditional methods on the basis of microwave synthesis of the boron - tung oil phenolic resin, the improvement of resin in the traditional production of long hours, low efficiency, large energy-consuming , And other shortcomings on the basis of free phenol content resin solution, polymerization slow, poor comprehensive performance issues in order to meet the increasing quality, environmental protection, efficiency and so the demand. To this end, the issue will be efficient quickly, the microwave heating energy conservation and environmental protection technology used in the synthesis of thermoset phenolic resin, synthetic process through the screening, optimization, the resin modified modification process is the key conditions need to experiment Modification of determining the ratio of raw materials, temperature, reaction time, trying to develop a comprehensive performance excellent B - tung oil modified phenolic resin.
