Cross-linking agent for dithio-pyridine coatings
Dithiopyridine can react with sulfhydryl to form a disulfide bond within a wide pH range, and the optimal pH is 4-5. Due to the effect of 2-thiopyridine, the reaction can be determined by detecting its absorbance at 343nm. The commonly used disulfide cross-linking agents include LC - SPDP, vulcanization lc-spdp and PDPH.
Vinyl paint is made of cold molecules have a key of vinyl resin paint, belongs to this kind of resin with polyvinyl chloride, polyethylene, chlorinated polyvinyl chloride, poly vinyl acetate in polyvinyl acetal, polyacrylic ester synthetic rubber, etc.
Polyvinyl chloride resin paint: tenacity, non-flammable, its characteristic is film on the role of acid, alkali, oxidant and water stability, odourless, tasteless, good oil resistance, but not resistant to temperature above 70 ℃. The dissolving force is only dissolved in several solvents such as cyclohexanone, so it is only applied to the surface coating of plastic products. It has the corrosion of formaldehyde, ammonia and other media, so it is used in the formaldehyde and ammonia storage tank of chemical industry.
Vinyl perchloride resin paint: a single class of paint.
- vinyl chloride vinylidene chloride copolymer resin paint, good water resistance, chemical resistance, cold resistance, resistance to moisture, paint film is tough and resilient, the intensity is high, can dissolve in ester, ketone, all kind of solvents. Can be used as metal, wood, building materials and other waterproof and anti-chemical corrosion coatings.
Chloric ethylene vinyl acetate copolymer resin paint, since is a kind of dry coating, good corrosion resistance and acid resistance, alkali resistance performance, to stable oil and alcohol, can be used under 70 ℃, short-term can withstand 100 ℃ temperature. The film is dry and fast, tough and wear-resistant, and has the properties of moisture resistant and mildew proof.
Vinyl acetate for vinyl acetate:
1. Vinyl acetate latex paint: vinyl acetate emulsion paint is widely used in architecture, and it has good color protection and adhesion.
2. The polyvinyl acetal resin paint: it has excellent adhesion, perseverance, abrasion resistance, light resistance and aging resistance, resistant to moisture, heat and cold resistance, low temperature, high temperature can not sticky, soft can be used to manufacture all kinds of coating.
Styrene system for vinyl: the earliest application is latex paint, which is flexible and good, mainly used for interior architectural paint. Because the film is brittle and brittle, it will be replaced by vinyl acetate.
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
Ethylene paint made from certain by-products
1. Vinyl acetylene resin paint:
It has good drying, water resistance and chemical resistance to mineral oil. It does not soften in organic solvents. The disadvantage is that the solvent used is toxic, it has a bad smell, the adhesion is not very good, easy to become brittle, not to be resistant to the sun. This kind of resin can be used to produce cheap, good anti-corrosive coating, waterproof coating and oil resistant coating.
2. Polyene resin paint:
For the modified polyene resin enamelled film, it is easy to crack, brittle, and needs modification, and the modified polyene resin paint film is flexible and gas view is better. Oil resistant to coating, used for general indoor wood lacquer.
3. Styrene tar resin paint:
It has good waterproof, abrasion resistance, alkali resistance, ammonia resistance and anti-aging properties. Its disadvantage is that the quality is unstable, the smell is large and the heat resistance is poor. Generally used for the decoration of building walls, roofing waterproof and ground acid and alkali resistant coatings.
Other vinyl paint: trifluorochloroethylene coatings with excellent chemical resistance, low temperature resistance and excellent insulation resistance; It has chemical resistance and good weather resistance. There are excellent chemical resistant vinyl chloride, chlorinated polyether, polytetrachloro-ethylene coating.
