Water-based closed isocyanate paint crosslinking agent
Using aqueous polyurethane resin as main film former, and water closed isocyanate crosslinking agent, the surface wetting additives, adhesion agent and defoaming agent to cooperate, the preparation of the corona processing optical two-way stretch polyester film (BOPET) pre-coating film use water-based coating liquid online.
The effects of main film, crosslinking agent, various auxiliaries and coating liquid solid content on coating liquid and its precoating properties were studied. The research shows that the water-based coating can satisfy the process requirement of on-line coating. Adopts pre-coating film of the preparation of the coated fluid has excellent optical properties and apparent state, with the corona treatment optical BOPET under high temperature and high humidity environment and various functional surface coating has good adhesion performance.
Preparation of a fork with hydroxy ethyl phosphonic acid (HEDP) as a conversion of rust agent type conversion on rust coating, by adding different mass fraction of HEDP coating samples of salt spray test and electrochemical test and analysis, studies the conversion of HEDP as rust agent on rust corrosion resistance of coatings.
The quality score of HEDP is 5%, and the corrosion resistance is the best. Using the EDS analysis and infrared spectroscopy (ft-ir) technique, the anti-rust mechanism of HEDP and the reaction of rust were studied.
The EDS line scan showed that when HEDP was added to the water-based coating, the phosphorus concentration was concentrated on the boundary between the rust layer and the coating. The results of infrared test show that HEDP is mainly used to react with the rust's porous iron ore to produce chelate, forming a stable complex protective membrane and protecting the base.
The two-step synthesized can fluorinated acrylates prepolymer polymerization (FM), with the methyl glycidyl ester of acrylic (GMA) synthesized by the copolymerization of epoxy and long fluorine carbon chain of acrylate copolymer (CFPA). The structure of the polymer was characterized by the GPC and 1H NMR. The CFPA and epoxy E51 are mixed with the modified epoxy resin coating. The surface performance of the film and its properties were studied.
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
Results show that: add a small amount of the CFPA (0.5%) can make the coating hydrophobicity increased significantly (water contact Angle is 97.8 °, 2 methyl iodide contact Angle is 66.0 °, surface energy of 25.16 mN/m).
X-ray photoelectron spectroscopy (XPS), the study found that fluorine-containing acrylate polymer content was 4%, the CFPA fluorine content in surface modification of epoxy resin film is random containing fluorine containing epoxy acrylate (RFPA) 8.39 times that of the modified epoxy resin coating, fluorine concentration in the modified coating surface, make the hydrophobic material was improved. The properties of the modified coating were studied, and the results showed that the modified coating had high gel content, high hardness (4H), excellent adhesion (0 stage) and low absorption rate.
According to the different heat insulation mechanism, the reflective insulation coating with different functional filler is made. Test the internal temperature of different reflective insulation coatings in indoor and outdoor environments using homemade devices. This paper studies the influence of the functional packing of silica aerogel, phase change capsule, potassium hexatitanate, titanium powder, ceramic microbeads and infrared radiation powder on the coating properties of the coating.
Results show that although iodine tungsten lamp light and solar energy distribution varied in different bands, but the results of two specimens under light irradiation temperature changes, shows that by using iodine tungsten lamp simulate sunlight test coating of heat insulation performance is feasible under the sun.
The coating's best dry film thickness of the coating is about 300 mu m, and the heat insulation effect of the coating with the barrier type and phase change packing is increased with the thickness of the dry film. In the sun's radiation, the reflective packing heat insulation works best. In the night outdoor environment, the thermal radiation performance of the filler has little effect on the cooling effect of the coating.
