Self-repairing anti-glare waterborne polyurethane paint and preparation method thereof

The invention discloses anti-glare waterborne polyurethane paint with a self-repairing function and a preparation method thereof. The preparation method is characterized in that aliphatic polyether glycol subjected to dehydration treatment and diisocyanate are subjected to prepolymerization under the effect of organic tin catalyst; then, the aliphatic polyether glycol subjected to dehydration treatment is added to generate a segmented copolymer; primary chain extension is performed through dimethylolpropionic acid; neutralization is performed to form salt; deionized water and sodium sulfamate type chain extenders are subjected to emulsification and chain extension; sulfonic acid groups are introduced at a hard chain section; then, aliphatic diamine type or hydrazine chain extenders with higher reactivity is added, so that the rest isocyanate completely reacts; finally, the proper amount of auxiliary agents is mixed to obtain the waterborne polyurethane paint. The paint coating film has good diffusion performance and high transmissivity; the excellent anti-glare effect can be achieved without adding additional auxiliary agents or performing surface treatment; the coating film has the self repairing capability through a large number of reversible hydrogen bonds and sulfonic acid groups in polyurethane.

Preparation process of anti-dazzle diffusion plate

The invention relates to the technical field of illumination, in particular to a preparation process of an anti-dazzle diffusion plate. The preparation process comprises the steps of the steps of selecting 80 -120 parts of PS raw materials in parts by weight, adding a 0.1 to 0.5 parts light diffusant in parts by weight into the PS raw material, stirring and mixing 0.5 to 2 parts of diffusion powder and 0.01 to 0.05 part of a dispersing agent in parts by weight to form a mixture; adopting an extrusion process, adding the mixture into an extrusion forming machine to be extruded to form a diffusion plate; carrying out embossing on the diffusion plate by adopting an embossing roller with the pattern as convex polygons to make a honeycomb-shaped diffusion plate with a concave polygon pattern, and selecting cutter for cutting the diffusion plate. The honeycomb-shaped diffusion plate can shield light rays in all directions, glare can be effectively inhibited when a user sees from all directions, and the purpose of preventing glare can be achieved. When the anti-dazzle diffusion plate manufactured by adopting the process and the formula is applied to practical application, the light sourceis comfortable and soft, light transmission is uniform, glare is effectively controlled, and user experience is better.
