2017-3-1 17:32:21
Organic silicon high temperature resistant coatings with crosslinking agent, organic silicon high temperature resistant coatings on the crosslinking agent and under the action of room temperature curing catalyst, organic silicon resin first pay couplet membrane. With the rising of the temperature, the organic silicone resin, such as methyl, phenyl gradually break down.
In the process of decomposition, the breakup of the resin, pigments, such as steel constitute inorganic silicon crosslinking structure; Above 350 ℃, organic silicon resin completely decomposed into inorganic silica crosslinking structure, make the high temperature resistant organic silicone coating "second film"; Regardless of the single and double component of organic silicon high-temperature paint, there is the transformation process.
Part of high temperature resistant, low melting point glass powder is added to the paint when under the environment of high temperature after reaching the melting point of glass beads, glass beads can melt into a membrane, replacing the part of the organic silicon resin adhesion of the role of fillers, form a layer of loose silicide layer, make the "second film", high temperature resistant coating on substrate heat insulation and anti-corrosion effect.
The rapid industrial development in our country, high demand, high temperature resistant coatings and organic silicon high temperature resistant coating is because advantages such as good effect of high temperature resistant, low carbon environmental protection become the top of the high temperature resistant materials. Silicone heat resistant coatings, then, is how to withstand high temperature
Learned, silicone paint can resistance to high temperature over 400 degrees, is not itself the resin can be resistant to 400 degrees, silicone basically complete decomposition at 350 degrees. Silicone paint can resistance to high temperature, depends entirely on "convert".
Formula points:
Select a specific organic silicon resin as film-forming substance; Packing for talcum powder and glass powder; Solvent for xylene; Paint for graphite and ferrochrome black.
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.
Organic silicon high-temperature coating ratio of the total weight percentage as follows:
Organic silicon resin: 30-40%.
Chromium iron black: 25-35%.
Talcum powder: 10-20%.
Glass powder: 10-15%.
Xylene: 10-15%.
Graphite powder: right amount;
Organic silicon resin as phenyl chlorosilane, methyl chlorosilane and combination of fluorinated organic silicon compound monomer.
Silicone heat resistant coatings with normal temperature quick drying, high film tough, resistant to your performance is good, save energy, and the advantages of cheap, more can adapt to organic silicon industry development in our country at present are badly in need of high temperature resistant coating requirements.
Coating pigment volume concentration (PVC) is the most important characterization of coatings, the most basic parameters, widely used in coating industry early YanJi than describe the coating formulation of the pigment content, because the coating used in all kinds of pigments, fillers and basic material density is far, PVC is more scientific and reflects the performance of the coating.
Required coating with high gloss, high durability, unfavorable use high YanJi ratio formula, special coatings or functional coatings are need to use appropriate YanJi ratio according to actual situation.
