Abstract
The invention relates to a processing process flow of a pressure-sensitive adhesive for vehicle-mounted display, which comprises the following steps of firstly, adding 0.15-3% of initiator peroxide into 40-50 parts of soft monomer, 30-40 parts of hard monomer and 10-15 parts of functional monomer, and then adding a proper amount of solvent, wherein the weight ratio of the soft monomer to the functional monomer is 6: 4, putting a part of the mixture in a reaction kettle; step two, putting the other part in the step one in titration for stirring; step three, heating up and reacting to the required viscosity of 4000-; step four, cooling to 40 ℃, discharging for later use; step five, uniformly stirring the prepared acrylic resin in the later period by using a reinforcing agent polyisocyanate and amine which are coordinated with each other, a reactive diluent, 0.4-2% of a photoinitiator, 1-3% of a coupling agent and 10-15 parts of a plasticizer; sixthly, coating the solvent obtained in the fifth step; and step seven, the adhesive is more fully cured through later-stage secondary uv curing, and the ultraviolet curing pressure-sensitive adhesive has the advantages of good transparency, high and low temperature resistance, strong adhesive force, no yellowing, no shrinkage and good adhesion to glass and plastic films.
Description
Technical Field
The invention relates to the technical field of multilayer pressure-sensitive adhesive processing, in particular to a processing process flow of a pressure-sensitive adhesive for vehicle-mounted display.
Background
With the continuous prosperity of the global automobile market and the continuous promotion of the internet of vehicles, the degree of human-vehicle interaction intellectualization is deepened, the demand of people on the function and the intellectualization of vehicle-mounted display is increasing day by day, compared with the display screen used in the field of consumer electronics, the product structure and the use environment of the vehicle-mounted display screen are more complex, for example, in the process of driving in various harsh environments such as outdoor, high temperature, low temperature, desert, seaside and the like, the screen reliability is higher due to the common condition of jolt during driving and the phenomenon of waste heat of a front engine cabin and the like, meanwhile, compared with the screen of consumer electronics such as a mobile phone and the like, the requirement of the vehicle-mounted display screen on the safety performance is higher, the functions of glare resistance and scratch resistance are needed, but the vehicle-mounted adhesive tape manufactured on the existing processing market can warp all around after a long time of use, the color turns yellow and can shrink, meanwhile, the situation of weak adhesion to the plastic plate also occurs, so that a processing process flow of the pressure-sensitive adhesive for vehicle-mounted display needs to be designed to solve the problems.
