Classification of curing agent (1). Aliphatic amine
Different range of products with different performance; High reactivity, can quickly at room temperature or low temperature curing; Is not sensitive to relative humidity. Have a certain color stability; Good resistance to chemical corrosion, especially solvent resistance; Used for heat curing, has good high temperature performance; Good resistance to chemical corrosion and has good electrical and mechanical properties.
Vinyl triamine DETA
Aminoethyl piperazine AE
Humid conditions under the low temperature curing; Good film performance (such as the excellent surface gloss); To prevent amine spray frost and water spot phenomenon; Good color stability; Has the very good bonding performance and chemical corrosion resistance; Curing time and storage with a wider range of choice; Used for heat curing, has good high temperature performance; Has the very good resistance to chemical corrosion and has good electrical and mechanical properties.
2 amino cyclohexane DACH
Isophorone diamine IPDA
Methylene double loop hexane amine 4, 4 '- PACM
Ethylenediamine EDA
Equivalent 15 H2NCH2CH2NH2 molecular weight 60, lively hydrogen, colorless liquid, every 100 standard resin with 6-8. Performance: toxic, stimulating smell, volatile, low viscosity, fast curing at room temperature. Used for bonding, pouring and coating. The amine with the increase of molecular weight, viscosity increases, the volatile and toxic decreases, and performance improvement. But they put a big heat, it is suitable for the shorter period. In general the smaller the higher the molecular weight they affected by the match the amount. Long-term exposure to multiple amine fat can cause dermatitis, their steam highly toxic, must be very careful when operating.
Classification of curing agent (2). Aromatic amine
M-phenylene diamine m - PDA MPD
(NH2) 2 c6h4, molecular weight 107, lively hydrogen equivalent 26.7, white crystalline (solid black? , melting point 62 ℃, every 100 standard resin with 14-16. Curing 60 ℃ for 2 hours + 150 ℃ for 2 hours. Applicable period 500 grams of 50 ℃ 2.5 hours, thermal deformation temperature of 150 ℃, bending strength, 1050 kg/cm2, the compressive strength of 710 kg/cm2, the tensile strength of 540 kg/cm2, elongation is 3.0%, the impact strength of 0.2-0.3 feet - pounds per inch, rockwell hardness of 108. Dielectric constant (50 hz 23 ℃) 3.3, power factor (50 hz 23 ℃) 0.007, heat resistance, corrosion resistance, good electric properties, low toxicity. As a solid, the use of inconvenient, must be noticed when mixed with resin heating prevent gel.
Chinese name: Diethyl toluene diamine(DETDA)
Physical and chemical properties: light yellow transparent liquid, slightly soluble in water, soluble in alcohols, ethers, ketones and other polar organic solvents, and polyether, polyester polyol compatibility.
Density 1.022
Viscosity (20 ℃) ??mPa·ss290±10
Pour Point ℃-9
Boiling point of310°C
Flash Point°C161.1°C
Between benzene dimethylamine MXDA
C6H4 (NH2CH2), molecular weight 135, lively hydrogen equivalent 33.2, colorless liquid, resin with 16 to 18 per 100 standard. Curing at room temperature for 24 hours + 70 ℃ for 1 hour or at room temperature 4 days. Applicable period 100 grams of 25 ℃ for 50 minutes, thermal deformation temperature of 130-150 ℃, the bending strength of 1200 kg/cm2, the compressive strength of 1030 kg/cm2, the tensile strength of 720 kg/cm2, elongation is 6.7%, dielectric constant (50 hz 23 ℃) 4.0, the power factor (50 hz 23 ℃) 0.005, volume resistance is greater than 2 x1016 Ω. Cm, room temperature curing heat resistance, corrosion resistance, good electric properties, low toxicity. Low curing temperature, low viscosity, low toxicity, long period and good solvent resistance. It is easy to absorb carbon dioxide from the air causes products of bubbles.
Classification of curing agent (3) amide amine
Different amide, according to the different reactivity. Low viscosity. Render good adhesive performance; Under the condition of damp good curing; Amide modified can get faster curing speed and chemical stability.
Classification of curing agent (4). Latent curing amine
Dicyandiamide (DICY) is a kind of potential curing agent, has more than six months of stability; By a variety of product form and particle size. Imidazole is latent catalyst of epoxy system, storage time can be from a few hours to 6 months. They can be used as a curing agent of the other good promoter, such as dicyandiamide and anhydride.
Classification of curing agent (5). Urea alternatives
In dicyandiamide promoting agent, can be used for low toxicity of Monuron and Diuron alternatives.
