Polyester/acrylic powder coatings with crosslinking agent
2017-3-22 20:47:42
Polyester/acrylic powder coatings with crosslinking agent, the application of low temperature crosslinking resin has become increasingly popular, the durability of super weatherability resin to further improve, a new hybrid varieties, such as polyester/acrylic powder coating has also developed a super weatherability and durability of fluorine resin powder coatings, as well as 180 ~ 180 ℃ / crosslinking conditions for 20 minutes with multiple isocyanate crosslinking hydroxyl fluororesin powder coating.
In terms of the use of the crosslinking agent, Europe and the United States in recent years has been gradually canceled toxic TGIC (isocyanate three glycidyl ester) application, switch to hydroxyl silane in amide, and so on. At present the main research direction of this aspect is development can improve the construction speed of the process and how to reduce the thickness of the coating, and to reduce particle size and improve reaction activity is to decrease the thickness of the coating and the key to improve the construction speed.
Polyester, the pluralistic alcohol and acid polycondensation for polymer. Refers to gather b two terephthalate (PET), traditionally including polyethylene terephthalate succinic ester (PBT) and linear thermoplastic resin such as aromatic esters.
Polyester is a kind of excellent performance, USES a wide range of engineering plastics. Also can be made of polyester fiber and polyester film. Polyester include polyester resin and polyester elastomer. Polyester resin and include gather b two terephthalate (PET) and polyethylene terephthalate succinic ester (PBT)) and aromatic esters (PAR), etc. Polyester elastomer (TPEE) generally by dimethyl terephthalic acid, 1, 4 - ding two alcohol and poly (butyl alcohol polymerization and chain segment includes hard segment and soft segment part, as a thermoplastic elastomer.
Acrylic acid is an important organic synthetic raw material and synthetic resin monomer, is very fast polymerization of vinyl monomers. Is the most simple of unsaturated carboxylic acid, consists of a vinyl and carboxyl. Pure acrylic acid is a colorless clear liquid with characteristic of irritating smell. It with water, alcohol, ether and chloroform miscibility, is made from oil refinery propylene preparation. Most used to manufacture acrylic acid methyl ester, ethyl acetate, butyl acetate, hydroxyl ethyl acrylate classes.
Acrylic acid and acrylic ester can homopolymerization and copolymerization, the polymer used in synthetic resin, synthetic fiber, high absorbent resin, building materials, coatings and other industrial sectors. Acrylic professional standards is the TLV - TWA 6 mg/m3; TWA 30 mg/cubic meter. Acrylic poison material Data is 79-10-7 (Hazardous Substances Data).
In recent years, the propylene oxidation made many improvements in the aspect of catalyst and process, has become the main method of production of acrylic acid.
Chinese name: Diethyl toluene diamine(DETDA)
Chinese alias: aryl, aryl diethyl - aryl - methyl-p-phenylenediamine

Acrylic chemical properties
1, flammable, the steam can form explosive mixtures with air, caused an explosion of the combustion flame, high heat. Strong reaction can occur with antioxidants. If encounter high fever, can happen polymerization and released a lot of heat caused by the vessel rupture and explosion accidents. Encounter heat, light, moisture, peroxide and iron easily caused by the blast.
2 joint response, has the double bond and carboxyl functional groups, can happen addition, functional group and ester exchange reaction, long preparation polycyclic and heterocyclic compounds, easily by hydrogen reduction of propionic acid, formic acid and acetic acid alkali can be broken down into.
3, with a strong acid. Corrosive. Chemical properties and lively. Easy to aggregate and become transparent white powder. Generate propionic acid reduction. 2 - chloropropionic acid and hydrochloric acid addition generated when. Acrylic characteristic of carboxylic acid reaction, reaction with alcohol can also get the corresponding esters.
Acrylic acid and its esters itself or blended with other monomers, polymerization reaction happens homopolymer or copolymer. Usually with acrylic copolymer monomer including amides, acrylonitrile and butadiene styrene, vinyl, etc. This kind of polymer can be used in the production of various plastics, coatings, adhesives, elastomers, floor light agent and coating.
4, this product has strong corrosive, moderate toxicity. Its aqueous solution or high concentrations of vapors may irritate the skin and mucous membrane. Rat oral LD50 to 590 mg/kg. Do not contact with acrylic acid solution or steam, operation is to wear good clothes and working cap, protective glasses and rubber gloves. Production equipment should be closed. Work and storage place with good ventilation.
