Problems solved by technology
[0005] However, there are also some insurmountable problems in the application of the above glues: when the permanent glue is peeled off from the object to be attached, a large area of glue will remain on the surface of the object to be attached. The cleanliness of objects caused a lot of trouble, and today's daily chemical, medical, and advertising industries are increasingly dissatisfied with this phenomenon
Removable glue is not very adaptable to curved surfaces due to its low viscosity, and it is easy to cause warping. Moreover, the retention and temperature resistance of removable glue products are poor, which affects its use. Scope, such as medical high-temperature disinfection field, such products cannot be used directly

Embodiment Construction
[0023] The following are specific examples of the present invention to further describe the technical solutions of the present invention, but the present invention is not limited to these examples.
[0024] The comprehensive self-adhesive manufacturing process includes the following steps:
[0025] 1) Add emulsifier, comonomer and deionized water into the emulsification tank according to the set ratio, and stir thoroughly for 30 minutes to obtain the pre-emulsion for later use;
[0026] 2), adding deionized water in the reactor, then heating up to 80 degrees Celsius, adding 8 to 10 wt% of the pre-emulsion and an initiator to prepare the seed emulsion;
[0027] 3) After the blue phase of the seed emulsion appears, add the pre-emulsion and initiator continuously within 3 to 4 hours, and control the reaction temperature between 82 and 85 degrees Celsius; after the addition, keep it warm for one hour, and then cool down to room temperature After adding other additives and stirrin...

Abstract
The invention provides a comprehensive adhesive sticker manufacturing process and application, and the comprehensive adhesive sticker manufacturing process comprises the following steps: adding an emulsifier, a comonomer and deionized water into an emulsification kettle according to a set proportion, and fully stirring for 30 minutes to obtain a pre-emulsion for later use; deionized water is added into a reaction kettle, then the temperature is raised to 80 DEG C, 8-10 wt% of the pre-emulsion and an initiator are added, and seed emulsion is prepared; after a blue phase appears in the seed emulsion, continuously dropwise adding the pre-emulsion and an initiator within 3-4 hours, and controlling the reaction temperature to be 82-85 DEG C; after dropwise adding is completed, heat preservation is conducted for one hour, then cooling is conducted to the room temperature, other auxiliaries are added, even stirring is conducted, filtering and discharging are conducted, and a material A is obtained; adding at least one external cross-linking agent into the material group A to serve as a material group B; and stirring and mixing the prepared group A material and the prepared group B material according to the use ratio to prepare finished glue with the viscosity of 100-500mpa. S, and coating a cloth body with the finished glue to form the adhesive sticker tape.
Description
technical field [0001] The invention belongs to the technical field of daily chemical production, and relates to a self-adhesive, in particular to a comprehensive self-adhesive manufacturing process and application. Background technique [0002] The glue used in existing self-adhesive products is classified according to the glue property, and there are permanent glue and removable glue. [0003] Permanent glue is characterized by high viscosity and good adhesion to the object to be pasted. It can be applied to objects with a certain degree of curvature and low surface polarity, and has a certain temperature resistance. It is widely used in daily chemical, medical, logistics and other industries. [0004] Removable glue is characterized by strong cohesion and weak viscosity, and there will be no glue residue on the surface of the sticker when it is peeled off from the sticker. [0005] However, there are also some insurmountable problems in the application of the above glue...
