Embodiment 1

[0031] see figure 1 , an environmentally friendly and pollution-free biodegradable adhesive tape, comprising a substrate layer 1, an adhesive layer 2 formed on one side of the substrate layer 1 and a release layer 3 formed on the other side of the substrate layer 1, the substrate layer 1 is Cellulose film, the adhesive layer 2 is made of adhesive, and an acrylic resin layer 4 is arranged between the base material layer 1 and the adhesive layer 2 .

[0032] The manufacturing process of the above-mentioned environmentally friendly and non-polluting biodegradable adhesive tape is carried out according to the following steps:

[0033] S1: Provide a base material, coat the first surface of the base material with acrylic resin, and dry at 60° C. to form a base material layer 1 having an acrylic resin layer 4;

[0034] S2: Apply 0.1 g of artificial wax per square meter of the substrate on the second side of the substrate, and dry at 60°C to form a release layer 3;

[0035] S3: Prov...

Embodiment 2

[0037] In this embodiment, the structure of the environmentally friendly and pollution-free biodegradable adhesive tape is the same as that of Embodiment 1, the difference is: its production process is carried out according to the following steps:

[0038] S1: Provide a base material, coat the first surface of the base material with acrylic resin, and dry at 55°C to form a base material layer 1 with an acrylic resin layer 4;

[0039] S2: Apply 0.18 grams of artificial wax per square meter of the substrate on the second side of the substrate, and dry at 55°C to form a release layer 3;

[0040] S3: Provide pressure-sensitive adhesive, water and hydrogen peroxide, mix the pressure-sensitive adhesive and water in a weight ratio of 40:60, then add hydrogen peroxide, and the amount of hydrogen peroxide added is 0.4% of the total mass of the pressure-sensitive adhesive and water to make an adhesive; The adhesive is coated on the upper surface of the acrylic resin layer 4 and dried at...

Embodiment 3

[0042] In this embodiment, the structure of the environmentally friendly and pollution-free biodegradable adhesive tape is the same as that of Embodiment 1, the difference is: its production process is carried out according to the following steps:

[0043] S1: Provide a base material, coat the first surface of the base material with acrylic resin, and dry at 50° C. to form a base material layer 1 having an acrylic resin layer 4;

[0044] S2: Apply 0.3 grams of artificial wax per square meter of the substrate on the second side of the substrate, and dry at 50°C to form a release layer 3;

[0045] S3: Provide pressure-sensitive adhesive, water and hydrogen peroxide, mix the pressure-sensitive adhesive and water in a weight ratio of 50:50, then add hydrogen peroxide, and the amount of hydrogen peroxide added is 0.6% of the total mass of the pressure-sensitive adhesive and water to make an adhesive; The adhesive is coated on the upper surface of the acrylic resin layer 4 and dried...

Abstract

The invention provides an environment-friendly pollution-free biodegradable adhesive tape, and belongs to the technical field of adhesive materials. An environment-friendly pollution-free biodegradable adhesive tape comprises a base material layer, an adhesive layer formed on one side of the base material layer and a release layer formed on the other side of the base material layer, the base material layer is a cellulose membrane, the adhesive layer is made of an adhesive, and an acrylic resin layer is arranged between the base material layer and the adhesive layer. According to the environment-friendly pollution-free biodegradable adhesive tape, the initial adhesion, permanent adhesion and peel strength of the adhesive tape can be improved, and the visual effect is improved.

Description

technical field [0001] The invention belongs to the technical field of adhesive materials, and in particular relates to an environment-friendly and pollution-free biodegradable adhesive tape and a manufacturing process thereof. Background technique [0002] At this stage, the tapes used in the industry are all traditional BOPP tapes. This tape uses biaxially oriented polypropylene film as the base layer and is a non-degradable synthetic polymer material. The raw material comes from petroleum resources. , it is not degradable in a short time after use, which will cause "white pollution" and "microplastic" harm to the environment. However, with the gradual enhancement of people's awareness of environmental protection, the demand for degradable and non-polluting environmentally friendly products is getting higher and higher. Therefore, the use of degradable materials to replace non-degradable materials can achieve the green development of the industry. [0003] At present, th...
