Polyamide coatings crosslinking agent
The polyamide coatings crosslinking agent was formed by polycondensation of fatty acids and fatty amines, such as: 9, 11 - linoleic acid and 9, 12 - linoleic acid dimer reaction, and then with 2 molecule DETA for the amide reaction.
The characteristics of polyamide crosslinking agent
(1) volatile and toxic;
(2) good compatibility with EP;
(3) the chemical measurement requirements are not strict and the dosage can vary between 40 and 100 PHR.
(4) it has a good toughening effect on crosslinking;
(5) low heat release effect and longer application period.
Polyamide crosslinking agent disadvantages: low heat resistance of crosslinking, chemical resistance and solvent resistance is poorer, the viscosity, crosslinking reaction activity is not high, low temperature crosslinking sex difference, when necessary, and other highly active crosslinking agent and or join a promoter.
Polyamide is the general term for the polymer containing the amide group in the main chain repeating unit.Polyamide can be polymerized from the inner acid amine, or polyamide and di-acid condensation.Polyamide has good comprehensive performance, including mechanical properties, heat resistance, abrasion resistance, chemical resistance and self-lubrication, and low friction coefficient, have certain flame retardant, easy processing, suitable for reinforced with glass fiber and other packing, improve performance and expand the application range.
Polyamide plastic is developed on the basis of poly phthalein amine fiber, is the earliest to withstand the load of thermoplastics, and the five common engineering plastics in the production is the largest and most varieties, USES the most widespread species.Polyamide plastic is a long history and a wide range of general engineering plastics, engineering plastics market in the world in 2000 allocated for PA, PC, POM, 32% and 11% 35% 10% 10% 10%, PPO, PBT, PET, UHMWPE 2%, high performance engineering plastics (PPS, LCP, PEEK, PEI, containing fluorine plastic PESU, PVDF, etc.) of 2%.

The synthesis of polyamide is an important milestone in the development of polymer chemistry.The international debate on the theory of polymer chain structure is mainly supported by the lack of clear and unsuspected experimental facts.The polycondensation reaction was not studied very much at that time, and the condensation was not complete.
Carrothers used far more than the usual method of organic synthesis, and when he was doing polymeric condensation, he had a strict ratio of the reactants to the reactants, with a difference of less than 1 percent.The degree of condensation is quite thorough, exceeding 99.5%, and thus synthesizing the polymer with a molecular weight of about 20,000.
Carothers studies have indicated that the polymer is a kind of real macromolecules, can be obtained from known organic reactions, the polycondensation reaction of each molecule contains two or more than two active group, these groups through covalent bond connection each other, not by a force not sure simple small molecules will be gathered together, which reveals the rule of polycondensation reaction.
Carrotherstone's study of polymerization reaction divides the polymer compounds into two main groups: one is the condensation polymer which is obtained by condensation polymerization;The other class is the addition of polymers, which are obtained by the addition of polymerization.Carothers assistant Florida (1910 ~ 1986), Paul j. Flory polyamide are summarized and a series of polycondensation reaction, proposed the polycondensation reaction in 1939 all the activity of functional group has the same basic principle, and put forward the polycondensation reaction kinetics and molecular weight and the quantitative relationship between polycondensation reaction.
Later, the statistical mechanics of the polymer solution and the statistical mechanics of the polymer were studied, and the Nobel Prize for chemistry was awarded in 1974.The synthesis of polyamide is a powerful demonstration of the existence of macromolecules, so that the theory of staudingg is firmly established and the polymer chemistry has been established.
