2017-3-24 22:54:38
Heat transfer powder coating crosslinking agent,From the basic composition of powder coating, ink powder coating with no obvious difference, general powder coatings are made by resin, crosslinking agent, pigments, fillers and additives, etc. Because of the heat transfer powder coating painting after the completion of the required to pass through thermal transfer process, on the selection of materials, attention should be paid to the following:
For outdoor use powder coating raw materials must be chosen weatherability;
Due to thermal transfer is baking under the condition of high temperature and high pressure, so the performance of the coating film forming matter of thermal transfer wood grain effect is bigger, generally choose the polyester resin varieties with high glass transition temperature, thus powder coating couplet membrane after crosslinking density is big, coating on the surface of high hardness, thermal transfer process, it is not easy to glue paper, it is not easy to produce fog spots;
For inferior smooth peace light powder coating, the formulation selection of flatting agent system should have good stability, ensure that in the process of thermal transfer film gloss can basically remained stable
On the amount of pigment, considering the wood grain transfer paper printing ink penetration and grain clarity, adding amount of powder coating due to lower than normal;
Graphic products to add basic such as aid flow ping agent, degassing agent, etc., according to the normal formula amount can be added, if it is used in glue water transfer printing process, attention should be paid to control the use of waxy compounds class additives, if this kind of additive dosage is too high, easy to produce in the process of heat transfer glue brush glue contraction, with wood grain transfer paper can't complete joint coating level, wood grain transfer printing color depth is inconsistent;
In order to make the heat transfer effect is better, facilitate at the same time of thermal transfer paper or thermal transfer film and coating, raw material market has ink additives products, according to the type and content of product requirements through the test.
Crosslinking agent is also known as curing agent, curing agent, curing agent, it can make linear or mild branched macromolecules into a 3 d mesh structure, improving strength, heat resistance, abrasion resistance, solvent resistance, such as performance, can be used for foam or not foam products.
Common organic peroxide crosslinking agent for:
DCP: namely dicumyl peroxide, the most commonly used, 1.08 g/cm3 density, melting point 42 ℃ and decomposition temperature of 120 ~ 125 ℃, the refractive index of 1.54, 117 ℃ has a half-life of 10 hours, often associated with zinc oxide and use, improve the strength and aging resistance.
