Abstract

The invention relates to a preparing method of a PDLC (polymer dispersed liquid crystal) dimming glass film. The method particularly comprises the following steps that in a light shading environment, resin, photoinitiators, HPMA (hydroxypropyl methacrylate), OPPEA (ortho-phenyl phenoxyl ethyl acrylate) and LMA (lauryl methacrylate) are proportionally mixed; after the mixing, the materials are uniformly stirred for about 30 minutes at the room temperature being about 25 DEG C; a mixture A is obtained; 35 percent of the mixture A is mixed with 65 percent of liquid crystals, and the mixture is uniformly stored for about 30 minutes at the room temperature about 25 DEG C; a mixture B is obtained; 0.5-percent 20um nanometer materials are added to be mixed with the mixture B, and the mixture is uniformly stirred for about 30 minutes at the room temperature being about 25 DEG C; finally, PDLC raw materials are obtained; coating and pressing are carried out; the curing process is carried out. The method provided by the invention includes the PDLC raw material preparation and a film production method. The production cost of the PDLC film is greatly reduced.

Description

technical field

[0001] The invention relates to the field of glass film preparation, in particular to a method for preparing a PDLC dimming glass film. Background technique

[0002] At present, the market has no specific national standards for PDLC and the products it manufactures, such as dimming glass, and each manufacturer can only approach the best product quality standard according to its own production process level, the main hard indicators, open-state transmittance The higher the better, the best transmittance of the front light-adjusting film is about 80% at most, the more opaque the off state, the better, and the best transmittance in the off state is about 5%. In addition, low voltage, high switching times, good bonding of two layers of ITO, not easy to open the glue, good bonding between PDLC and glass, no bubbles, etc., are the main hard indicators to measure the quality of the switchable glass.

[0003] However, the production process of the glass film with th...
