Crosslinking agent for esters of esters
The ester ring is an amine compound containing ester rings (cycloethyl, heteroxic, nitrogen hexaplase) in the molecular structure. Most of them are low-viscosity liquids, which are longer than fatty amines, and are superior to fatty amine and polyamide.
Ester cyclohexaniline crosslinking agent: montane diamine
The relative molecular weight is 170, containing four active hydrogen atoms, and the calculated dose is 22 percent. At room temperature the duration of the application is 8h. The heating temperature is 93 ℃, colorless transparent liquid. The crosslinking agent with low toxicity, easy to absorb carbon dioxide from the air, mixed with liquid bisphenol A epoxy resin, the resin viscosity reduction, long period, fast crosslinking and crosslinking system: 80 ℃ ~ 130 ℃ / 0.5/2 h h, after crosslinking, can improve its heat resistance.
Ester cyclohexane crosslinking agent: n-aep (n-aep)
Molecular weight 128, density 0.98, lively three hydrogens, calculate dosage is 23%, the applicable period for 17 min at room temperature, the crosslinking agent is colorless transparent liquid, crosslinking properties similar to diethylene triamine, impact resistant performance is good, mainly used in the manufacture of plastic tools.
Esters of esters: isofortone diamine
3-methyl-3, 5, 5-trimethylcyclohexylamine, which is a mixture of cis and trans, and shows the different properties of the normal diamine. The crosslinking agent is of long duration and similar to montane diamine. It can be crosslinked at room temperature, but only in phase B, which needs to be heated and crosslinked. The colour stability of crosslinked products and excellent drug resistance. Its simple degeneration or using the appropriate additives, can be a ideal under the condition of low temperature, high humidity, crosslinking agent, suitable for solvent-free paints, coatings, structure, casting resin, can be injected sealant, etc.
Chinese name: Diethyl toluene diamine(DETDA)Diethyltoluenediamine packing： net weight 200KG/ galvanized iron drum (a small cabinet pallet loaded 16 tons), 1000KG/IB barrels (a small cabinet loaded 18 tons or 23 tons of ISOTANK).
1, 3 - double (1, 3-bac) cyclohexane (1, 3-bac) is made from the hydrogenation of the dimethylbenzene diamine (MXDA). The product is very basic and easy to absorb the carbon dioxide in the air. It is usually kept in a container with nitrogen seal, which has irritant eyes and skin. It can be used as the crosslinking agent of epoxy resin, and it can be cross-linked with high temperature crosslinking, heat resistance, water resistance and drug resistance. Due to low viscosity, good technology.
A crosslinking agent containing an imide structure. The compounds containing imide have high heat resistance, and the introduction of such compounds as crosslinking agent into epoxy resin can effectively improve the heat resistance of the epoxy resin crosslinking.
Bimaleimide has good heat resistance, but less process. The aromatic diamine crosslinking agent and double maleic imide blending with epoxy resin system, not only can improve the composition of process performance, but also can improve the heat resistance of polymer and its reinforced plastics.
Crosslinking agent with E - 51 epoxy resin in mass ratio of 1:2, epoxy resin adhesive system (GB/T7123.2-2002, observed at room temperature (25 ℃) stored under the different period of crosslinking system viscosity, the changes of maneuverability and the latent crosslinking system after 90 days, the viscosity increases obviously, not account for more than three months storage period.
In the reaction, the optimal molar ratio of methyl isobutyl ketone and diphenylamine was 2:1, the synthesis yield was 89%, and the structure of the synthesized products was characterized by the Fourier transform infrared spectrometer. The results show that the target product is generated. Synthesis of the proceeds of the crosslinking agent with E - 51 epoxy resin made by the quality match of 1:2 one-component adhesive, has more than 90 d storage period at room temperature, under a certain temperature of crosslinking experimental results as follows: 120 ℃, the crosslinking time of 120 min.
From the molecular formula, cyanide was introduced, the molecular structure changed, and its crystallization changed obviously. The viscosity has increased, but it is still the crosslinking agent with low viscosity, which has no influence on the process performance of the construction of the structure.
