Crosslinking agent for optical crosslinking coating
When the light crosslinking agent is added to the epoxy gel, when the matte irradiation is stable, when exposed to ultraviolet or visible light, it will decompose and cross-link the epoxy tree. Photocrosslinking agent and visible cross linking agent.
The main cationic polymer crosslinking agents, including the aromatic diazonium salt, triaryl sulfuric salt, diaryl group, and aromatic compounds, etc. The aromatic diazonium salt in epoxy resin has the problem of leg stability and yellow change. The two aryl iodide is very stable, and its epoxy resin composition has been applied for more than one year. Triaryl sulphide is the most widely used and can form thick film.
The visible cross-linking agent is composed of two aromatic iodine pick-pick salt with dye. Joined o. alicyclic epoxy resin in 3% of Ar2 Ⅸ and o. 15% of dye, the tungsten light 2 ~ 3 min crosslinking. The bisphenol AD epoxy resin (index 1.573) and fluorinated epoxy resin (refraction 1.405), and the adhesives of the diaryl sulphide salt, were dissociated from BF by light exposure. Almost instantaneous crosslinking, used as a silica gel adhesive for silica glass.
Water-based acrylic coating has no solvent and has good environmental performance. It is different from water-based acrylic latex paint. In addition to the general water-based acrylic coating system, it also develops water-based anti-carbonized acrylic coatings.
The water-based acrylic coating system for bridge concrete structures is as follows: water-based acrylic acid anti-alkali primer (25 mu m); Water-based acrylic intermediate paint (65 mu m); Water-based acrylic surface paint (65 mu m); The total thickness is 155 mu m.
The solvent oil is expected to be used in alternative toluene, xylene and mixed aromatics. At present, the solvent oil in domestic market is mainly alkane and naphthene. The alkane is divided into positive and heterogeneous groups, and its chemical stability at normal temperature is better, and its density is small and its viscosity is good. The chemical stability of naphthene is good. It is similar to alkanes, low freezing point, good lubrication and non-toxic.
The mixed alkanes are also called D series dearomatic solvent oils, which are free of polycyclic aromatic hydrocarbons and are controlled in the range of 100-150 PPM. It is not toxic to people and stable in performance. However, it is mainly composed of naphthene and alkanes, without polarity, and with many resins with polar groups, it has no solubility to many resins with polar groups.
Chinese name: Diethyl toluene diamine(DETDA)
Chinese alias: aryl, aryl diethyl - aryl - methyl-p-phenylenediamine
English name: Benzenediamine, ar, ar-diethyl-ar-methyl-English aliases:Diethyltoluenediamine; ar, ar-Diethyl-ar-methylbenzenediamine;Diethylmethylbenzenediamine;
CAS No. :68479-98-1
EINECS No. :270 -877-4
Molecular formula: C11H18N2
Molecular Weight: 178.28
Boiling point: 310 ℃
Refractive index: 1.581
Flash Point: > 140 ℃
Inchi: InChI = 1/C11H18N2/c1-4-8-6-7 (3) 10 (12) 11 (13) 9 (8) 5-2/h6H ,4-5,12-13H2 ,1-3H3 density : 1.022
Risk Codes: R10; R35
RIDADR: UN 3082
Safety instructions: S2; S26; S39; S61
Packing Group: III
Hazard Class: 6.1
Directly in the formulation, D series dearomatic solvent oil substitute for toluene, xylene and trimethylbenzene are proved to be difficult! The solubility of developing and supporting solvent is expected to improve. With the solubility improvement, the alkane solvent is more widely used for its low toxicity and relatively stable cost.
Ethylene glycol ether solvents are being replaced by other detoxification solvents due to toxicity. Currently, propylene glycol ether solvents are widely used in coatings.
Ether ester solvent is a multi - functional group, high boiling point oxygen solvent. The molecule contains both ether and ester and alkyl. The polarity and non-polar parts of the same molecule are mutually restricted and mutually exclusive. It to a variety of resin high dissolving power, to other high proportion of mixed solvent soluble and comprehensive performance such as volatile rate slower can make the coating after most of the solvent evaporation, can still keep a good liquidity. To make the coating uniform, the gloss and adhesion are improved accordingly.
The ether ester solvents used in coatings are mainly dialcohol ether and alkolic propionate (e.g. EEP: 3-ethoxypropionate). The most widely used is propylene glycol methyl ether acetate (PMA).
Coating anticorrosive most widely application in the metal tank corrosion, with the development of technology, its heavy-duty coating will get long-term progress, toward multi-function, long life, and the direction of the whole process of corrosion, get more extensive application.
