2017-4-5 11:06:14
More nitrogen organism class c coating crosslinking agent, more nitrogen c organism (polyaziridine) crosslinking.
N propyl organism compounds used in paint, textile and medical and other fields for many years, in recent years as the room temperature of waterborne polyurethane crosslinking agent is used, it can react with carboxyl, hydroxyl and so on, and in the acidic environment also can be together, but are quite stable in alkaline environment. Often with two-component system, when using.
The crosslinked membrane water resistance, chemical resistance, high temperature resistance and adhesion to have markedly improved, if for baking performance is better. Coating at room temperature with the crosslinking agent added should be finished within 3 ~ 5 d, lest produce hydrolysis, loss of activity.
Functionality to 3 CX - 100, the equivalent of 166, when n propyl organism with paint base with carboxyl content quality than about 1:1. General addition amount for the amount of the emulsion of 1% ~ 3%, the best method of 1:1 water diluted to join. Because of its good water soluble, manual mixing can be used. The other kind of crosslinking agent has certain toxicity, and the price is higher, affect the promotion.
Crosslinking temperature of crosslinking agent and crosslinking of heat resistance has a lot to do. Similarly, in the same kind of crosslinking agent, although has the same functionality, but due to the different chemical structure, its properties and crosslinking behavior is also different. Therefore, a comprehensive understanding of have the same functionality, and chemical structure of different traits and characteristics of polyamine crosslinking agent, for choosing crosslinking agent, is very important.
In terms of hue, alicyclic most shallow, basically is transparent, and aliphatic and aromatic, its color degree is quite significant. In terms of viscosity, also have very big different, alicyclic but few Pa zero point zero s, the polyamide is very thick, for Pa s., aromatic amines are solid. Applicable period length is just the reverse of crosslinking sex completely, the highest aliphatic reactivity, and alicyclic, amide, aromatic reduced in turn.
Hue: (optimal) alicyclic - and aliphatic amide - aromatic amine (bad)
Cooked degrees: (low) alicyclic - aliphatic and aromatic - amide (high)
Shelf life: (long) and aromatic amides - alicyclic - aliphatic (short)
Crosslinking sex: (fast) the aliphatic, alicyclic - amide - aromatic (slow)
Stimulus: (strong) aliphatic and aromatic - alicyclic - amide (weak)
More amine chemical structure and properties of crosslinking agent
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Uses:
The product is identical to Ethancure 100 and Lonza DETDA 80, DETDA is very effective polyurethane elastomer chain extender; also be used as polyurethane and epoxy resin curing agent, epoxy resin of an antioxidant, industrial oils and lubricants . In addition, also as intermediates in organic synthesis.Especially for the RIM (reaction injection molding), is important in the field of spray polyurea chain extender species. Also can be used for casting polyurethane elastomer (CPU) and a curing agent, epoxy curing agent, epoxy resin of antioxidants, lubricants and industrial oils other antioxidants.
In addition, the gloss, flexibility, adhesion, acid resistance, resistance to water, also has a certain regularity.
Sheen: (optimal) and aromatic alicyclic amine, polyamide, fat (bad)
Flexible: (soft) - aliphatic, alicyclic - aromatic polyamide (just)
Adhesion: (optimal) - alicyclic - aliphatic and aromatic polyamide (good)
Acid (optimal) aromatic - alicyclic - and aliphatic polyamide (bad)
Water resistance: (optimal) polyamide - fatty amine - alicyclic amines, aromatic amine (good)
Polyamine crosslinking agent of chemical structure and bisphenol A and properties of crosslinked resin
For luster, best aromatic, aliphatic is the worst. The property affected by crosslinking temperature, temperature rise, luster. As for softness, functionality, the distance between the long polyamide better some, while high crosslinking density of aromatic amine. Is the opposite of softness, heat resistance and adhesion is consistent with softness. Drug resistance (acid) affected by the chemical structure, aromatic is fine, fat amine and polyamide are vulnerable to chemical corrosion. Controlled by the mass concentration of functionality, water resistance, functionality, quality of low concentration, high degree of hydrophobic polyamide class more resistant to water, and functionality, high concentration of aromatic.
