The properties and uses
of saturated polyester resin in the field of chemical production
Abstract:

saturated polyester resin is an important chemical raw material, with excellent performance, widely used in coatings, adhesives, composites and other fields. This paper introduces the properties, synthesis methods, application fields and development prospects of saturated polyester resin in detail, aiming at deepening the understanding and understanding of saturated polyester resin.

1. Introduction

saturated polyester resin (Saturated Polyester Resin, referred to as SPR) is a kind of polybasic acid and polyol through esterification of polymer compounds. Because its molecular structure does not contain unsaturated double bonds, it has good chemical corrosion resistance, aging resistance, heat resistance and other properties, and has become an important material in the field of chemical production raw materials.

2. The properties of saturated polyester resins

1. Physical properties: Saturated polyester resins are usually colorless or light yellow transparent liquids or solids with good gloss and flexibility.
2. chemical properties: saturated polyester resin has excellent chemical corrosion resistance, can resist the erosion of acid, alkali, salt and other chemicals. In addition, it also has good aging resistance and can maintain good performance in harsh environments such as high temperature and high humidity. The synthesis method of

the synthesis method of
saturated polyester resin mainly uses esterification reaction, that is, polybasic acid and polyol react under certain conditions to produce ester compounds. Commonly used polybasic acids include adipic acid, terephthalic acid and the like, and polyhydric alcohols include ethylene glycol, propylene glycol and the like. In order to ensure the quality and performance of the product, it is necessary to control the reaction temperature, time and the amount of catalyst.

4. the application field of saturated polyester resin

1. coating: saturated polyester resin can be used as the main film-forming material of coating, with excellent weather resistance, chemical resistance and decoration, widely used in construction, automobile, furniture and other fields.
2. Adhesive: saturated polyester resin can be used as the main component of the adhesive, used for the bonding of wood, metal, glass and other materials, with high bonding strength and durability.
3. composite materials: saturated polyester resin can be used as the matrix resin of composite materials, and composite with glass fiber, carbon fiber and other reinforced materials to make composite materials with high strength and light weight, which are widely used in aerospace, automobile, construction and other fields.

5. development prospects

With the continuous development of science and technology, the application field of saturated polyester resin will continue to expand. In the future, saturated polyester resin will pay more attention to the development of environmental protection, high efficiency and functionalization to meet the needs of different fields. At the same time, with the continuous improvement of material performance requirements, the modification of saturated polyester resin will also become an important development direction in the future.

conclusion: As an important chemical raw material,

saturated polyester resin has excellent performance and wide application fields. Through the in-depth understanding of the properties, synthesis methods, application fields and development prospects of saturated polyester resin, it is helpful to better apply and develop this important material, and make greater contributions to the development of chemical production raw materials.
