Indoor flooring and outdoor wall decoration of PVC tiles, Feather Flag Poles PVC coating is in the thick mass of asbestos paper mixed with a foaming agent, and then into the low-temperature drying tunnel to the formation of the PVC foam layer, and after cooling the winding and then number of color photo gravure inhibitors, such as by adding a 2 color ink to make this color part of the dent, the printed paper surface coating of transparent PVC surface protection layer after processing by the foaming furnace, ie the cohomology and pattern embossing embossed foam products. As the of building materials, with low processing costs, innovative features.
Foam used in the production of packaging materials. Foam packaging has the advantages of wear, pressure, water-resistant, bright color, breathable, moisture and other role, the look, feel worthy and comparable to natural leather.
With the continuous development of
The ② foam material. Foam of the material in addition to materials, paper, plastics, textiles, glass, leather, plywood, sheet metal, etc., foam ink.
a. Microcystis foam ink. Microcystis foam ink is foaming microcapsules dispersed to link the compound, and add some additives made. The ink in the paper, textile and other substrates by the method of , after the low-temperature drying, baking heated to
Microcapsules foam ink formula:
60% of the acrylate copolymer
5% of the other ingredients
Microcapsules. Microcystis is the main ingredient for the manufacture of microcapsules foam ink. It differs from the blowing agent used in the manufacture of foam plastics industry. The principle is the monomer to polymer synthesis, made 5 to 80 microns in diameter, and tiny plastic sphere filled with a low boiling point solvents. Microcapsules after heating, the capsule of the low boiling point solvent is vapourised by heating the microcapsules diameter of 5 to 30 times. Acrylate copolymer. Acrylate copolymer type of acrylic acid A, B, D, and octyl. Under the general law of the carbon chain is the longer, the better the transparency of the copolymer, commonly used in carbon chain length to adjust the hardness. Is to use acrylic as a link to material in the microcapsules foam ink. This ester link material is oil, the aqueous non-ionic.
Urea. Urea has good moisture absorption, can promote the expansion and diffusion in the microcapsules is vapourised by heating, but also in the acidity and paste, to protect the substrate, stabilizing effect on the water and milk foam ink.
