C9 petroleum resin properties and uses

1. Introduction

C9 petroleum resin is an important chemical production raw materials, widely used in rubber, coatings, inks, adhesives and other fields. In this paper, the properties and uses of C9 petroleum resin are introduced in detail.

2. C9 petroleum resin properties

1. physical properties
C9 petroleum resin is usually light yellow to dark brown viscous liquid or solid, with a certain special smell. Its molecular weight distribution is wide, the softening point is generally between 80-120 ℃, and it has high viscosity and thermal stability.
2. Chemical properties
C9 petroleum resin is mainly composed of hydrocarbons, rich in aromatic and olefin structures, with high unsaturation and polarity. Because of its molecular structure contains more active groups, such as carboxyl, phenolic hydroxyl and so on, C9 petroleum resin has good reactivity and compatibility.

3. C9 petroleum resin use

1.
in the field of rubber C9 petroleum resin in the field of rubber has a wide range of applications, can be used as rubber tackifier, reinforcing agent and filler. It can increase the viscosity of rubber, improve processing performance, and give rubber products good wear resistance, tear resistance and anti-aging performance.
2.
in the field of coatings C9 petroleum resin can be used as a film-forming material in coatings, which can improve the adhesion, hardness, water resistance and chemical resistance of coatings. In addition, it can also be used as a pigment dispersant to improve the dispersibility and stability of the pigment.
3.
in the field of ink C9 petroleum resin can be used as thickener, binder and drying oil in ink, which can improve the viscosity, adhesion and drying performance of ink. At the same time, it can also improve the printability and scratch resistance of the ink.
4. Adhesive field
C9 petroleum resin can be used as the main resin in the adhesive to improve the adhesive strength, heat resistance and water resistance. At the same time, it can also improve the workability and storage stability of the adhesive.

4. conclusion

In short, C9 petroleum resin as an important chemical production raw material, has a wide range of applications and good performance. In the future development, with the continuous progress of science and technology and the expansion of application fields, the performance and use of C9 petroleum resin will be further improved and explored.
