Problems solved by technology

[0003] The hot-melt masking tape currently on the market has an unreasonable adhesive formula, which makes its initial adhesion unsuitable. As the temperature rises, its viscosity will gradually change, but when the temperature rises above 80 ° C, its resistance The shortcomings of the temperature difference began to show again
In addition, its cohesive force is not enough, its tensile strength is weak, and its adhesive force is not enough. When the tape is pasted for a long time, it will cause residual glue when the tape is torn off.

Embodiment Construction

[0024] The present invention is further elaborated below by way of specific embodiments:

[0025] This embodiment provides a production process for hot-melt masking tape, which specifically includes the following steps:

[0026] a. Select masking paper 1, and dip the masking paper 1 in carboxylated styrene-butadiene latex;

[0027] b. Use a mixture of tackifying resin emulsion and modified styrene-butadiene emulsion as a primer to spray one side of the masking paper 1 at room temperature, and perform high-temperature treatment;

[0028] c. Use a mixture of vinegar-acrylic emulsion and silicone as a release agent to coat the other side of the masking paper 1 with silicon, and perform high-temperature treatment;

[0029] d. Use hot melt adhesive to scrape coat the surface of the primer at a temperature of 100-190°C.

[0030] The temperature of the high temperature treatment in the step b is 100-150°C, and the treatment time is 10-40s. The temperature of the high temperature t...

Abstract

The invention provides a hot melt masking tape and a production process thereof. The production process comprises the following steps: firstly carrying out immersion treatment on masking paper in carboxylated styrene-butadiene latex; spraying a mixture of tackifying resin emulsion and modified styrene-butadiene emulsion as a primer onto one side of the masking paper at normal temperature and carrying out high-temperature treatment; then coating silicon on the other side of the masking paper by using a mixture of vinyl acetate-acrylic emulsion and organic silicon as a release agent and carrying out high-temperature treatment; coating hot melt glue on the surface of the primer with a knife. The hot melt masking tape produced by the production process has excellent temperature resistance and water resistance and does not have adhesive residues.

Description

technical field [0001] The present invention relates to a hot-melt type masking tape and its production process, in particular to a hot-melt type masking tape which dips masking paper and has excellent temperature resistance and no glue residue during use and its production process . Background technique [0002] Hot-melt masking tape is a high-tech decoration and spraying paper (also known as ribbon paper because of its special performance), it is widely used in interior decoration, spraying of household appliances and spraying of high-end luxury cars . Hot-melt masking tape is a roll-shaped tape made of masking paper and adhesive as the main raw materials. One side of the masking paper is coated with adhesive, and the other side is coated with anti-adhesive material (also known as release agent). . Its color separation effect has a clear and clear boundary, and also has an arc art effect, which has brought a new technological revolution to the decoration and spraying in...
