Problems solved by technology

However, the viscosity of the existing scotch tape will change with the change of temperature and time when it is used
Some are the higher the temperature, the higher the adhesion. When the temperature is high, the adhesion is very strong and it is difficult to tear it off. In severe cases, it cannot be torn off and even the glue remains on the object; At the same time, the adhesive force will also fade with time, so that the adhesion between the object and the tape is not strong, and it will fall off during use; structural damage, etc.
The emergence of these problems will affect the normal use of the posted product

Embodiment 1

[0018] Dissolve 20 parts by weight of konjac fly powder in ethanol, add 16 parts by weight of acrylate and 2 parts by weight of tackifying resin and mix evenly, adjust the pH of the mixed solution to 4.5, and then add 2 parts by weight of thiol containing ether structure Mix evenly, and finally add 0.2 parts by weight of leveling agent and mix evenly to obtain glue for scotch tape. The glue is coated on the base cloth of the BOPP film, the coating thickness is 25 microns, and the scotch tape is obtained after curing.

Embodiment 2

[0020] Dissolve 30 parts by weight of konjac powder in ethanol, add 24 parts by weight of acrylate and 5 parts by weight of tackifying resin and mix evenly, adjust the pH of the mixed solution to 5, and then add 4 parts by weight of thiol containing ether structure Mix evenly, and finally add 0.6 parts by weight of leveling agent and mix evenly to obtain glue for scotch tape. The glue is coated on the base cloth of the BOPP film with a coating thickness of 50 microns, and a scotch tape is obtained after curing.

Embodiment 3

[0022] Dissolve 40 parts by weight of konjac powder in ethanol, add 30 parts by weight of methacrylate and 8 parts by weight of tackifying resin and mix evenly, adjust the pH of the mixed solution to 5.5, and then add 7 parts by weight of ether-containing The mercaptan is mixed evenly, and finally 1 part by weight of a leveling agent is added and mixed evenly to obtain glue for scotch tape. The glue is coated on the base cloth of the BOPP film with a coating thickness of 30 microns, and a scotch tape is obtained after curing.

Abstract

The invention provides glue used for a transparent adhesive tape and a preparation method of the glue. The glue comprises the following components in parts by mass: 15-30 parts of acrylate monomer, 20-40 parts of konjac flying powder, 1-10 parts of thiol, 1-10 parts of tackifying resin and 0.1-1 part of a levelling agent. The transparent adhesive tape containing the glue provided by the invention has the characteristics of high transparency, high cleanliness and the like, the adhesion strength of the glue changes slightly with temperature and time, the glue has better adhesion stability and a certain waterproof function, and no residue glue exists.

Description

technical field [0001] The invention relates to the field of glue, in particular to a glue used for scotch tape and a preparation method thereof. Background technique [0002] The scotch tape is made on the basis of the original film after high-voltage corona to make one surface rough and then coated with glue. After being divided into small rolls, it is the tape we use every day. [0003] At present, scotch tape is widely used. But the viscosity of existing scotch tape all can change with temperature time variation when using. Some are the higher the temperature, the higher the adhesion. When the temperature is high, the adhesion is very strong and it is difficult to tear it off. In severe cases, it cannot be torn off and even the glue remains on the object; At the same time, the adhesive force will also fade with time, so that the adhesion between the object and the tape is not strong, and it will fall off during use; damage to the structure, etc. The emergence of thes...
