What kind of material is the resin made of?
Resin is the main raw materials for the manufacture of plastics, paint is also used the system (the main film-forming material, coating such as alkyd resin, acrylic resin, synthetic fatty acid resin, the resin in the Yangtze River Delta and Pearl River Delta are also relatively strong in the paint industry, such as Changxin chemical, Nuplex resin, three resin, Ying DSM syntech resins), adhesives, insulating material, synthetic resin in industrial production, is widely used in separation and purification of impurities in liquid, with macroporous adsorption resin, ion exchange resin, and some special resin.
Resin classification:1, according to resin synthesis reaction classificationAccording to this method, resins can be divided into polymers and condensation polymers. Polymers are polymers made by addition polymerization, and their chain structures are chemically identical to those of monomers, such as polyethylene, polystyrene, and polytetrafluoroethylene.Condensation polymer is a polymer prepared by condensation polymerization. Its structural unit is chemically different from that of monomer, such as phenolic resin, polyester resin, polyamide resin and so on.2, according to resin molecular backbone composition classificationAccording to this method, resins can be classified into carbon chain polymers, hetero chain polymers, and elemental organic polymers.A carbon chain polymer is a polymer composed of carbon atoms of the backbone, such as polyethylene, polystyrene, etc..A chain polymer is a polymer consisting of atoms of two or more elements, such as carbon, oxygen, nitrogen, sulfur, etc., such as POM, polyamide, polysulfone and polyether. Organic polymer refers to the main chain does not necessarily contain carbon atoms, mainly by silicon, oxygen, aluminum, titanium, boron, sulfur, phosphorus and other elements of the atoms, such as organic silicon.
Resin usually refers to softening or melting range after heating. When softening, it tends to flow under external force. At normal temperature, it is solid, semi solid, and sometimes liquid organic polymer. Broadly speaking, any polymer compound that can be used as plastic material for processing raw materials is called resin.
Resins are made of natural resins and synthetic resins. Natural resin is an amorphous organic matter from the secretions of plants and animals in nature, such as rosin, shellac, amber, etc.. Resins are resins derived from the synthesis of simple organic compounds by chemical synthesis or by the chemical reaction of certain natural products.
