Problems solved by technology

[0004] (1) The release agents currently on the market are resistant to friction and solvents, but have low hardness
If the oil is not sprayed, the printed pattern will easily fall off, which will affect the use of the product;
[0005] (2) Some resin-type release agents have poor paving properties, and the release layer is hard and brittle after film formation, which is only suitable for hard surface transfer
And it is not resistant to solvents, and the effect of adhesion on the surface of PET is not good

Abstract

The invention provides a heat transfer release agent, a preparation method thereof and an oil injection operation-free use method thereof. The formula of the heat transfer release agent comprises a curing agent and a component which comprises a polyester resin, silicone oil, a defoamer, a leveling agent and a diluent according to certain weight percentages. The preparation method comprises the following steps: 1, stirring and uniformly mixing the diluent and the polyester resin; 2, stirring and uniformly mixing the defoamer, the silicone oil and the leveling agent; 2, and blending and uniformly mixing the component obtained in step 1 and the component obtained in step 2 to obtain the heat transfer release agent. In the use method, the thickness of the coating release layer is not less than 6mum, and the transferred release layer can be used as a protection layer; and by testing, the hardness can reach 2-3H, so a vanish baking effect is reached, and the oil injection operation is omitted, thereby the heat transfer release agent can be widely applied to the plastic industry.

Description

technical field [0001] The invention relates to a thermal transfer release agent and a method for preparing and using the same, in particular to a thermal transfer release agent capable of eliminating an oil spraying process and a method for preparing and using the same. Background technique [0002] In order to increase the added value of the product and make its appearance more beautiful, many manufacturers print patterns and colors on the shell of the product. This method mainly uses thermal transfer printing technology, that is, first coat the release agent, dry it, print the pattern, hot melt adhesive, and then transfer the pattern and the release layer to the product shell at a certain temperature, and then Do the oil spray. Thus, the patterns and colors printed on the shell of the product are durable and durable. [0003] However, the transfer printing release agents currently used in the industry generally have the following defects: [0004] (1) The release agent...
