Abstract:Tung oil is an important dry grease. In order to overcome the deficiencies of traditional processes in oil production, the preparation of tung oil was carried out by the butane-subcritical method. A response surface optimization experiment was carried out based on Design-Expert software, and the best process parameters were obtained. The extraction temperature was 42.98 °C, the extraction time was 43.77 min, the particle size of the raw material was 38.88 mesh, and the oil yield of tung oil under this conditio… Show more
“…Under alkaline conditions, TO-modified phenolic resin and cotton or wood pulp cellulose paper made of laminate material, the product has high heat resistance, low water absorption, excellent insulation properties, high mechanical strength and easy processing performance, and it can be applied to the coated board industry. In addition, TO has good cardboard waterproof performance, and it is widely used in construction [28], coatings, inks, ships, cardboard [29,30] and nano composite materials [31], furniture wood [32] and other aspects.…”
Tung oil (TO)/ultraviolet (UV) photo-composite curing material possesses the characteristics of low curing temperature, low material shrinkage and low environmental pollution. Accordingly, this material must be developed and utilized with the conjugated double bonds contained in the long chain of the main structure (α-tung acid) molecules in the refined TO. The aforementioned material can be chemically modified using a variety of chemical methods to develop a new TO-based UV photocurable material due to its unique chemical properties. This work reviews the research progress of TO/UV photo-composite curing materials in recent years. Firstly, the chemical structure and application of TO and UV Photocatalysis Technology were briefly introduced. Secondly, the research status of novel TO/UV photo-composite curing materials developed by the Diels-Alder reaction was discussed. The method and curing effect of the UV curing system constructed by other chemically modified TO were also discussed. Thereafter, the application of TO in industrial production is introduced from four directions: the application of TO in biodiesel, the application in synthetic resin, the application in self-healing coating and microcapsules and other applications. Finally, the research and application prospects of TO/UV photo-composite curing materials were presented.
