[ technical field ] A method for producing a semiconductor device

The invention relates to the technical field of high polymer materials, in particular to anti-sticking gloss oil for luggage cloth of a PVC coating and a preparation method thereof.

[ background of the invention ]

gloss oil is a product that has emerged with the rapid development of the packaging and printing industry. The gloss oil is coated on the surface of an object by adopting different printing processes to form a continuous solid layer with firm adhesion and certain strength, and the gloss oil is shiny after film formation, has superior performances such as hardness and wear resistance and the like, can well play a role in protecting printed pictures and texts, and is widely applied to the outer surfaces of food, beverage, shoes, clothes and packing boxes for cigarettes and wines based on the advantages.

in order to ensure the waterproof effect when the case cloth is made, a designer usually adds a PVC coating on the inner surface of the case cloth, and the PVC coating contains a large amount of plasticizer which can not be dried at normal temperature and can easily migrate to the surface of the bottom material when the temperature rises. The phenomenon of ink anti-sticking is easily caused when the traditional solvent type ink is printed on the luggage cloth, so that a large amount of defective products in a printing factory are accumulated, and the requirements of people cannot be met.

[ summary of the invention ]
