Abstract

The invention belongs to the technical field of functional building paint and relates to photochromic glass paint and a preparation method thereof. The photochromic glass paint is prepared from the following raw materials in weigh ratio: 20 to 50 parts of prepolymer, 5 to 20 parts of active monomer, 0.1 to 1 part of initiator, 5 to 20 parts of color changing powder, 0.1 to 1 part of wetting agent,0.1 to 1 part of dispersant, 0.5 to 3 parts of adhesion promoter, 0.5 to 2 parts of enhancer and 0.5 to 3 parts of nano material. The surface of general glass is simply coated with one layer of the photochromic glass paint disclosed by the invention, so that the general glass can achieve a photochromic effect; thus, the surface of the general glass can be coated with the paint in a large scale infactories to manufacture photochromic glass, and construction can be performed in existing building sites to manufacture the photochromic glass.

Example Embodiment

[0029] Example 1: Preparation and detection of photochromic glass paint (1)

[0030] The cover glass paint was prepared with the following raw materials in the weight ratio.

[0031]

[0032] Among them, the prepolymer is urethane acrylate; the reactive monomer is dipropylene glycol dipropylene; the initiator is 2-hydroxy-2-methyl-1-phenylacetone; the color changing powder is diaryl vinyl, average particle size The diameter is 3 microns; the wetting agent is TEGO-4100; the dispersing agent is DISPERBYK-110; the adhesion promoter is aminopropyltrimethoxysilane; the reinforcing agent is KH570; the nano material is nano aluminum oxide, the average particle size 10nm.

[0033] The specific preparation process method is as follows.

[0034] (1) First weigh the active monomer, add wetting agent and dispersant under stirring, and continue stirring for 30 minutes;

[0035] (2) Add color-changing powder and nano materials, continue to stir and disperse for 30 minutes;

[0036] (3) Add enhancer, initiator, and prepolymer, and continue stirring for 20 minutes;

[0037] (4) Add adhesion promoter before use and stir evenly.

[0038] After the prepared cover glass paint is painted with ordinary glass (brushing thickness 20-50 microns), the visible light transmittance is 91.5%, the hardness is 6H, and the adhesion is 0 grade.

[0039] The visible light transmittance test refers to the standard GB/T 5433-2008 "Daily glass light transmittance measurement method"; the hardness test refers to the standard GB/T 6739-2006 "Paint and varnish pencil method to determine the hardness of paint film"; adhesion test Refer to the standard GB/T 9286-1998 "Cross-cut test of paint and varnish film", and the following is the same.
