Abstract

The invention discloses an adhesive for a waterproof masking tape, characterized by comprising components in percentages by weight: 10%-30% of natural rubber, 10%-20% of synthetic rubber, 10%-30% of viscosity-increasing resin, 1%-3% of an accelerant, 2%-5% of an age resister and a solvent of the rest. The adhesive for the waterproof masking tape and the waterproof masking tape disclosed by the invention has a waterproof function and is suitable for the use in occasions of spraying paint in automobiles, baking varnish, spraying water to polish the paint surface, repairing the paint surface and the like. Furthermore, after the use, no residual adhesive is remained after the tape is torn off. In the automobile varnish baking process, the waterproof masking tape disclosed by the invention is suitable for the varnish baking procedure at a temperature up to 80 DEG C. The raw materials in the invention are aqueous emulsions so that no environmental protection exists in production and use processes.

Description

technical field [0001] The invention relates to an adhesive for a waterproof masking tape and a waterproof masking tape. Background technique [0002] In the process of automobile production and use, it is often necessary to paint and bake the various parts of the automobile, especially the outer surface. However, not every part of the outer surface requires the same painting and baking treatment; and during the treatment process, most of them need to be painted and baked, and then need to be polished and repaired. [0003] In order to carry out different painting and baking treatments on various parts, some parts need to be covered. Simple methods can be used for shielding, such as using cardboard to cover parts that do not need to be treated or require other special treatment. But this method is inefficient and cumbersome to operate. [0004] The commonly used masking method is to use masking tape, that is, use a certain adhesive tape to stick it on the parts that do no...
