Abstract

The invention relates to a pressure sensitive adhesive tape for high-temperature resistant masking and a preparation method thereof. The pressure sensitive adhesive tape consists of a substrate layer, an isolator layer, a release agent layer, a primer layer and an adhesive layer, wherein the isolator layer and the release agent layer sequentially cover the upper surface of the substrate layer, and the primer layer and the adhesive layer sequentially cover the lower surface of the substrate layer. The pressure sensitive adhesive tape prepared by the invention, compared with the prior art, can avoid crack and residue when being peeled off after being roasted for 60 minutes at high temperature of 180 DEG C, and the adhesive property has strong adhesive property and can avoid a wrapping phenomenon when being used.

Description

technical field [0001] The invention relates to a pressure-sensitive adhesive tape and a preparation method thereof, in particular to a high-temperature-resistant pressure-sensitive adhesive tape for shielding and a preparation method thereof. Background technique [0002] High temperature tape is mainly used for spray painting, varnish leather processing, painting masking and fixing in the manufacturing process of electronic parts, printed circuit boards and high temperature masking treatment, etc. During the painting and high-temperature baking of the car body in the automobile manufacturing process and automobile repair, the small area that is not painted can be directly pasted and covered with adhesive tape, and the large area can be pasted with adhesive tape on the larger area. on the border of the part to be painted. [0003] When the car is painted and baked, the pressure-sensitive tape may have to withstand a period of time (such as 30min-60min) high temperature (su...
