Problems solved by technology

However, the peelable blue glue needs a higher heating temperature (baking at 120-150°C for 20-30 minutes) to achieve curing. Obviously, such a high temperature will have a certain impact on electronic components such as touch screens, and will also increase energy consumption. consumption
[0010] In addition to this kind of thermal curing, there are relatively environmentally friendly and efficient UV curing, such as patent 201310003268.6 and patent 201310388295.X. This UV-curing peelable blue glue has very strict requirements for the glue construction process (dispensing). Compared with heat curing and UV curing, room temperature rapid curing is more efficient and cost-effective. Currently, there are few products of room temperature rapid curing peelable blue glue on the market, and there are volatile toxic solvents (such as triphenyl Solvent), insufficient adhesion, good elasticity and poor reworkability, slow curing speed and other shortcomings

Abstract

The invention relates to a method for preparing environment-friendly room-temperature quick curing peelable blue gel.The method is characterized by including the steps that tackifying resin, plasticizer, stabilizer, filler, a solvent A, a thixotropic agent and pigment are mixed together according to the proportion, heated to 40-50 DEG C and placed into a stirrer to be stirred for 10-20 min at low speed, and a plasticization system is obtained; modified styrene thermoplastic elastomers are placed into the stirrer, heated to 40-50 DEG C, added into the plasticization system and stirred for 20-30 min at high speed, the mixture is cooled during stirring, the temperature is kept below 70 DEG C, and a peelable blue gel base material is obtained; the obtained peelable blue gel base material is ground twice in a three-roller grinding machine, the temperature is kept below 70 DEG C during grinding, and peelable blue gel is obtained; the obtained peelable blue gel is vacuumized so that bubbles can be removed, and the room-temperature quick curing peelable blue gel is obtained.The method has the advantages that the obtained peelable blue gel can be quickly cured at room temperature, is low in toxin and odor, has excellent elasticity and good rework performance and has more excellent adhesion performance.

Description

technical field [0001] The invention relates to a preparation method of an environment-friendly room temperature quick-curing peelable blue glue. Background technique [0002] The traditional peelable blue glue (or peelable ink, peelable glue) is a one-component heat-curing adhesive that is blue and sticky. It has good curing performance and high temperature resistance (heating at 150°C for 15 minutes can cure completely, and can withstand high temperature of 300°C), and its biggest feature is easy peeling, strong toughness, no trace of residual glue and no need for secondary cleaning, so it has been Widely used in screen printing in the PCB (Printed Circuit Board) industry. [0003] With the rapid development of information technology and flat display technology, the application of touch screens is becoming more and more common. As large as information query systems in public places, as small as personal computers, tablet computers, and mobile phones, touch screens are cl...
