Description

Technical Field

[0001] The invention relates to the technical field of pressure-sensitive adhesive preparation, in particular to an environmentally friendly odorless pressure-sensitive adhesive preparation device and process. Background Art

[0002] The full name of pressure-sensitive adhesive is pressure-sensitive adhesive, also commonly known as self-adhesive, or simply pressure-sensitive adhesive. Pressure-sensitive adhesive products include pressure-sensitive adhesive tape, pressure-sensitive adhesive label paper, and pressure-sensitive film. Their full name is pressure-sensitive adhesive tape, pressure-sensitive adhesive label paper, and pressure-sensitive adhesive sheet, commonly known as tape, self-adhesive label paper, and pressure-sensitive film. This component has been adjusted to achieve better performance of the product. There are four main types of pressure-sensitive adhesives used in industry: solvent-based pressure-sensitive adhesive, emulsion-based pressure-sensitive adhesive, hot-melt pressure-sensitive adhesive, and radiation-curing pressure-sensitive adhesive. Pressure-sensitive adhesives are divided into rubber-based pressure-sensitive adhesives, polyacrylate-based pressure-sensitive adhesives, polyvinyl ether resins, polyurethane resins, polyisobutylene resins, etc. according to their polymers. Emulsion-based pressure-sensitive adhesives occupy an absolute dominant position. In recent years, With the expansion of demand for packaging, decoration, office supplies and various labels, people's demand for pressure-sensitive adhesives is also increasing. Acrylic pressure-sensitive adhesive emulsions have become the development direction of pressure-sensitive adhesives because they are non-toxic, non-polluting, and have excellent aging resistance, weather resistance, pressure sensitivity and adhesion, and have been widely used. In view of the characteristics of pressure-sensitive adhesives that are easy to stick to, not difficult to peel off, can be peeled without damage, and will not dry up for a long time, while selecting the main monomer and second monomer of acrylates, a variety of functional group monomers are introduced. Through repeated experiments and reasonable adjustment of the process formula, a multi-polymer polyacrylate pressure-sensitive adhesive emulsion with good comprehensive performance is screened and synthesized, which can be used in the production of double-sided tapes, trademark papers, etc. that require transfer coating technology.

[0003] For example, patent document CN103409103B discloses an environmentally friendly, high-temperature-resistant organosilicon pressure-sensitive adhesive. The adhesive is prepared by reacting the following components in parts by weight: 30-50 parts organosilicon rubber, 50-70 parts MQ organosilicon resin, 0.01-0.1 parts catalyst, and 60-70 parts solvent, wherein the solvent is a low-molecular-weight ester. The present invention can use low-molecular-weight esters, such as ethyl acetate, as a solvent. This is primarily due to the fact that when preparing the MQ organosilicon resin from waterglass, the waterglass is first purified to produce sodium silicate, which is then used to prepare the MQ organosilicon resin. This method produces an MQ organosilicon resin that does not produce gel and has a high number-average molecular weight. This resin improves the compatibility and adhesion of the pressure-sensitive adhesive. Furthermore, ethyl acetate can be used as a solvent in the preparation of the organosilicon pressure-sensitive adhesive, making it transparent, environmentally friendly, and non-toxic.

[0004] However, in the actual pressure-sensitive adhesive preparation process of this structure, each time the material is added, a certain amount of harmful gas will be generated. At this time, continuous stirring is required to stir out the harmful gas substances inside the pressure-sensitive adhesive raw materials, so as to achieve environmentally friendly and odorless pressure-sensitive adhesive preparation. However, the harmful gas usually cannot be efficiently and accurately processed and can only be collected in a centralized manner and then processed in a unified manner, which results in the exhaust gas prepared by the entire equipment being unable to be quickly processed, thereby affecting the overall efficient production operation of the pressure-sensitive adhesive of the equipment and being detrimental to daily use. Therefore, it is urgent to design an environmentally friendly and odorless pressure-sensitive adhesive preparation device and process to solve the above problems. Summary of the Invention

6. A process for preparing an environmentally friendly odorless pressure-sensitive adhesive, comprising: S1: First, the raw materials required for the preparation of the pressure-sensitive adhesive are transported to the pump (28) through the feed rack (30) and the feed pipe (29), and then pressurized to the inside of the rotating tube (26) by the pump (28). At this time, the driving motor (25) is started to drive the rotating tube (26) to perform a stable rotation operation as a whole, and the pressure-sensitive adhesive preparation raw materials inside the rotating tube (26) are quickly centrifuged and thrown out from the discharge hole (31), and an efficient stirring operation is performed through the rotating stirring blade (32). The first fan (36) inside the fan rack (35) is started, so that the air flow quickly enters the inside of the stirring rack (23) along the lifting rack (21) and the gas collecting cover (22), and the harmful gas generated by the mixing of the pressure-sensitive adhesive preparation raw materials is discharged from the barrier air-permeable pad (33) to the inside of the filter absorption rack (9) inside the connecting frame (8), and the harmful gas is absorbed and processed; S2: By starting the electric push rod (20) inside the push rod box (19), the lifting frame (21) as a whole is operated upward inside the rotating frame (18). During the movement, the docking sleeves (24) at the upper and lower ends of the stirring frame (23) are stably docked with the semi-arc groove (14) of the movable plate (12). The movable plate (12) is adaptively opened and closed under the action of the torsion shaft (11), ensuring smooth adjustment of the stirring frame (23) and effectively separating the mixing frames (6). The docking arc seat (34) at one end of the stirring frame (23) is positioned with the docking frame (41) and the docking roller (42) at one end of the connecting frame (7). Then, the previous feeding operation is repeated to transport the newly formed harmful gas to the corresponding filtering and absorbing frame (9) for accurate processing and absorption. The operation is repeated multiple times, thereby achieving proper processing of the harmful gas generated during the preparation of the pressure-sensitive adhesive. S3: The second fan (38) on the surface of the supporting base frame (2) is started, and the air flow inside the mixing frame (6) is quickly transported along the through groove (37) into the ventilation groove (15) of the L-shaped exhaust frame (1), and then the air flow is absorbed from bottom to top along the ventilation groove (15) inside the L-shaped exhaust frame (1) and all the filter absorption frames (9), and the treated gas is merged to comprehensively treat the harmful gas left inside the mixing frame (6), thereby improving the overall treatment effect of the harmful gas, and finally the air flow is quickly discharged from the exhaust seat (40) at the top of the L-shaped exhaust frame (1); S4: During actual preparation, the number of layers of the mixing frame (6) and the connecting frame (8) is selected according to actual needs. The mixing frame (6) and the connecting frame (8) are quickly spliced ​​together through the connecting frame (7), and then the rotating frame (18) is rotated and adjusted as a whole through the damping shaft (17). At this time, the combination of the mixing frame (6) and the connecting frame (8) is stacked and plugged onto the installation side frame (3) in sequence, and then the filter absorption frame (9) made of different materials is stably supported and installed inside the L-shaped exhaust frame (1) and the connecting frame (8) through the partition bar (16).
