Development Trends of Petroleum Resin Applied Technology

The development trend of petroleum resin technology is toward high performance and high value-added development, and attaches importance to environmental protection and production safety. Special structure petroleum resins and additives are developing towards refinement, functionalization, and curing under special circumstances. The cured product has high toughness, high strength, radiation resistance, high and low temperature resistance. As a result, the varieties of special resins, curing agents and diluents will have greater development, forming a multi-variety and small-batch production pattern. With the recent development of polymer physics, the development of varieties has focused on the use of chemical or non-chemical synthesis. The method is to prepare petroleum-rubber, petroleum-thermoplastics, various organic and inorganic filler composites and petroleum resin-based inorganic nanocomposites through blending and alloying.

1. Paint

The development trend of petroleum coatings is to reduce pollution, improve quality and safety, and develop functionality. Focus on the development of can coatings, anti-corrosion coatings, functional coatings and environmentally friendly coatings and their promotion and application. In particular, the development and quality improvement of water-based petroleum systems will be used in the automotive industry (such as electrophoretic coatings), home appliance industry, food industry (such as tank coatings), chemical industry (such as anti-corrosion coatings), and construction industries (such as floor coatings). Breakthroughs have been made in application fields such as coatings, construction adhesives, petroleum mortar and concrete.

2. Electronic materials

With the development of electronic equipment towards miniaturization, light weight, high performance and high functionality, electronic devices have also developed in the direction of high integration, thinness, and multilayer. Therefore, it is required to improve the resistance of petroleum packaging materials and copper clad laminates. Thermal, dielectric properties and toughness, reduce water absorption and internal stress. The current development focus is on petroleum resins and curing agents with high purity, high heat resistance, low water absorption and high toughness. For example, in petroleum resins and curing agents, the skeletons such as dicyclopentadiene, biphenyl, diphenyl ether, and drugs can greatly improve the heat resistance and electrical properties of petroleum cured products, and reduce water absorption. In addition, the research and development of the non-wave flame-retardant petroleum system has also attracted great attention at home and abroad.

3. High-performance petroleum composite materials

The research focus of high-performance petroleum composites is to improve heat and humidity resistance, compressive strength after impact, and mechanical properties between layers. In order to improve the heat and humidity resistance, just like the petroleum electronic materials, the skeletons such as Cai, dicyclopentadiene, biphenyl, diphenyl ether, drugs, etc. can be introduced into the petroleum resin and curing agent. In order to improve the compressive strength and interlayer mechanical properties after impact, the method of improving the fracture toughness of the petroleum cured product can be used, usually by adding rubber or heat-resistant thermoplastic resin to the petroleum resin to form a sea-island structure or a multiphase interpenetrating network structure. system.

4. Fireproof petroleum materials

The continuous occurrence of malignant fires has made people gradually realize that materials with flame retardancy are far from achieving the purpose of preventing fires. It is the first to propose requirements for fire resistance for aircraft materials, that is, it has performance requirements such as flame-retardant (flame retardant), less smoke, low toxicity (the gas produced is less toxic), and low heat release rate. The research and development of fireproof petroleum materials is of great importance not only for aviation and aerospace, but also for vehicles, ships, household appliances, high-rise buildings and public buildings.
