The main application areas of petroleum resin

Time:2021-11-30

Petroleum resin's excellent physical and mechanical properties, electrical insulation properties, bonding properties with various materials, and flexibility in its use process are not available in other thermosetting plastics. Therefore, it can be made into coatings, composite materials, casting materials, adhesives, molding materials and injection molding materials, and is widely used in various fields of the national economy.


1. Paint


The application of petroleum resin in coatings accounts for a large proportion, and it can be made into varieties with various characteristics and uses. The commonalities are as follows:


(1) Excellent chemical resistance, especially alkali resistance.


(2) The paint film has strong adhesion, especially to metal.


(3) It has good heat resistance and electrical insulation.


(4) The paint film has better color retention.


However, the bisphenol A petroleum resin coating has poor weather resistance, and the paint film is easy to pulverize and lose gloss in the outdoors, and it is not suitable for outdoor coatings and high-decorative materials. Therefore, petroleum resin coatings are mainly used as anti-corrosion paints, metal primers, and insulating paints.


2. Adhesive


In addition to the poor adhesion of petroleum resins to non-polar plastics such as polyolefins, it is also suitable for various metal materials such as aluminum, steel, iron, and copper; non-metallic materials such as glass, wood, concrete, etc.; and thermosetting plastics such as phenolic, Amino, unsaturated polyester, etc. have excellent bonding properties, so it is called the *** glue. Petroleum adhesives are an important variety of structural adhesives.


3. Electronic and electrical materials


Because of its many unique advantages, such as high insulation performance, high structural strength and good sealing performance, petroleum resin has been widely used in insulation and packaging of high and low voltage electrical appliances, motors and electronic components, and has developed rapidly. Mainly used:


(1) Pouring of insulation packages for electrical appliances and motors. Manufacturing of integrally sealed insulating packages for high and low voltage electrical appliances such as electromagnets, contactor coils, mutual inductors, and dry-type transformers. It has developed rapidly in the electrical industry. It has developed from normal pressure casting and vacuum casting to automatic pressure gel forming.


(2) It is widely used for potting insulation of devices equipped with electronic components and circuits. It has become an indispensable and important insulating material in the electronics industry.


(3) Electronic grade petroleum molding compound is used for plastic packaging of semiconductor components. It has developed extremely fast in recent years. Due to its superior performance, it has a tendency to replace traditional metal, ceramic and glass packaging.


(4) Petroleum laminated plastics are widely used in the fields of electronics and electrical appliances. Among them, the development of petroleum copper clad laminate is particularly rapid, and it has become one of the basic materials of the electronics industry.
