The composition and difficulties of the production process o

The production technology of artificial leather off type paper is mainly composed of two parts: the original paper coating and the embossing.

Release paper on paper or paper base have higher requirements, requiring only the shed high strength heat-resistant bulk water and other aspects also have strict requirements, in the paper the quantitative aspects of general use 125g/m2 more than the use of paper, coating machine production technology is difficult to control, bulk and the heat resistance of the base paper. The thickness is generally used softwood pulp and hardwood pulp ratio making way to control in heat resistance, heat addition agent in pulp to enhance the heat resistance of paper.

From the type of coating each have different characteristics different types, such as silicone resin coating has excellent stripping performance and heat resistance, solvent resistance and poor chromium complex type coating, polypropylene coating with high gloss but poor heat resistance.

In general, from the type of coating layer can be divided into two kinds, namely silicon release coating layer and non silicon coating from calvin.  Silicon based materials include silicone resin and modified silicone resin with alkyd resin and acrylic resin. Non silicon release materials include package chromium complex, methacrylic acid or fatty acid, polypropylene resin, polymethene resin TPX and other special resins, amino alkyd resin, epoxy resin and so on.
