Abstract

The invention discloses an aqueous pressure-sensitive adhesive for a heat-insulating broken bridge aluminum profile protection film and a preparation method thereof. The preparation method comprises:preparing a seed emulsion through a seed emulsion polymerization method, adding a pre-emulsion into the seed emulsion drop by drop, then adding an initiator into the emulsion in the later stage so that the reaction is full, cooling the system, adjusting pH, adding a defoaming agent and a wetting agent into the system, filtering the mixture and discharging the product. The invention also provides apreparation method of the heat-insulating broken bridge aluminum profile protection film. The preparation method comprises: adding a polyfunctional aziridine crosslinking agent into the aqueous pressure-sensitive adhesive, carrying out full mixing, uniformly coating a polyethylene film with the glue, carrying out baking through a baking channel and carrying out rolling. The protection film has good adhesion to a heat-insulating broken bridge aluminum profile and good high temperature and high humidity aging resistance. The pressure-sensitive adhesive emulsion utilizes the appropriate defoaming agent and wetting agent and is especially suitable for low-speed coating with a protective film (at 9-15 m / min).

Description

technical field [0001] The invention relates to the technical field of water-based pressure-sensitive adhesives for protective films, in particular to a water-based pressure-sensitive adhesive suitable for low-speed coating and a water-based pressure-sensitive adhesive for protective films of heat-insulating bridge-breaking aluminum profiles and a preparation method thereof. Background technique [0002] Aluminum alloy has good thermal conductivity. However, this physical characteristic is to be avoided by building doors and windows for thermal insulation and energy saving. Blocking the transfer of heat between the inside and outside of the aluminum profile is the only way to improve the energy-saving and thermal insulation performance of the aluminum profile. The heat-insulating broken bridge aluminum profile is also called the broken bridge aluminum alloy. Both sides are made of aluminum (it can be profiles of different cross-sections, or profiles of different colors wit...
