Synthesis and characterization of maleated rosin‐modified
Imide-containing vinyl fluorosilicone resin (MR-VFS) was synthesized from maleated rosin (MR). And then, with MR-VFS as a new polar cross-linking agent in a heat curable fluorosilicone rubber composition, a series of maleated rosin-modified fluorosilicone rubbers (MR-FSR) were obtained.
Preparation of rosin epoxy soybean oil acrylate with high bio
Rosin epoxy soybean oil acrylate (RBAESO-15 %) displayed a high bio-renewable carbon (89.6 %). RBAESO-15 % exhibits higher tensile strength (14.4 MPa) compared to AESO (3.2 MPa). RBAESO-15 % can be use in 3D printers with 10 s/slice.
Rosin is a natural resin whose unique chemical properties and biological origin have enabled its application in numerous industrial fields. rosin itself lacks sufficient mechanical performance and heat resistance, which limits its practical applications. To improve its properties, scientists have subjected rosin to various modification processes. One important method involves using rosin sourced from the Yan'an region for modification.
Yan'an, located in northwestern China, produces rosin with excellent characteristics due to its distinctive geographical and climatic conditions. Yan'an rosin not only boasts vibrant color but also demonstrates strong adhesiveness and plasticity, making it an ideal material for modification. By blending Yan'an rosin with other resins, modified resins with superior properties can be prepared. These modified resins enhance heat resistance, mechanical strength, and anti-aging performance while expanding their applicability in specific fields.
In industrial production, Yan'an rosin-modified resin has broad applications. For example, in construction, it can be used to produce waterproof coatings and adhesives, improving the water resistance and durability of buildings. In the electronics industry, it serves as an insulating material for manufacturing circuit boards and cables. Additionally, Yan'an rosin-modified resin is employed in automotive parts, furniture, and various plastic products.
Beyond industrial use, this modified resin plays a significant role in agriculture. Thanks to its strong adhesion and anti-aging properties, it is widely used in agricultural materials such as pesticide packaging and fertilizer bags. These products protect agricultural goods from environmental erosion, extend their lifespan, and reduce resource waste.
Environmentally, Yan'an rosin-modified resin also contributes positively. Its excellent degradability allows it to decompose naturally without causing long-term pollution, making it an ideal eco-friendly material for applications in landfills and wastewater treatment plants.
Despite its widespread use, several challenges remain. First, its relatively high production cost restricts large-scale adoption. Second, while the performance of Yan'an rosin-modified resin has improved significantly, fully replacing traditional plastics requires more time. Finally, as environmental awareness grows, enhancing the eco-friendliness of this resin remains a key focus for future research.
Yan'an rosin-modified resin holds vast potential as a versatile material. By optimizing production processes and improving quality, it is poised to play an even greater role in industrial and daily applications. Addressing existing challenges and pursuing solutions will further advance China's material science innovation.
