The application provides an RFID label composite device and composite process capable of realizing online multi-color printing, relates to the technical field of RFID production, and comprises a rack, wherein a pay-off mechanism, a die cutting seat, a digital printer, a label peeling unit, a guide shaft group, a peeling transition unit, a pressing assembly, a read-write marking unit and a winding mechanism are arranged on the rack; after label die cutting, online printing is performed; the printed label and label base paper are peeled once; the inlay layer is compounded to the label base paper; then, the printed label is compounded twice; the whole process only needs one label base paper, and the whole RFID label paper compounding can be completed; due to the great simplification of the compounding process, the device is integrated and simplified, and the production efficiency and product qualification rate are greatly improved.

The application discloses a composite polycarboxylic acid water reducing agent and a preparation method thereof, and relates to the technical field of composite polycarboxylic acid water reducing agents. The composite polycarboxylic acid water reducing agent is composed of the following components in a mass percentage: polycarboxylic acid water reducing agent mother liquor: 60-85%; slow-release slump retaining component: 5-20%; viscosity adjusting component: 3-15%; functional adjusting component: 0.1-5%; and the balance is water. The polycarboxylic acid mother liquor containing multiple active groups in the main chain provides an initial high water reducing rate, and the special slump retaining component with slow-release adsorption characteristics is used, so that the slump loss is basically zero for more than 2 hours, and the slump loss problem under high temperature and long distance transportation is solved. The modified lignin sulfonate is introduced as the viscosity adjusting component, which can effectively improve the cohesiveness and fluidity of low water-binder ratio concrete, so that the concrete is more easily pumped and constructed, and is particularly suitable for self-compacting concrete.
