AI Technical Summary

Problems solved by technology

[0002] The current UV shielding coatings are various, but there are still some problems in different degrees. The existing UV shielding coatings have a large shrinkage rate after photocuring and shrinkage stress, resulting in brittleness of the coating film, adhesion and durability. Poor impact force, poor flexibility and low hardness of the coating film, no corrosion resistance, easy yellowing and aging, etc.

Embodiment 1

[0007] Embodiment 1: including 80 parts of 2-hydroxy-4-octyloxybenzophenone, 450 parts of polyethylene glycol, 800 parts of ethanol, and 90 parts of xylene.

Embodiment 2

[0008] Embodiment 2: including 100 parts of 2-hydroxy-4-octyloxybenzophenone, 500 parts of polyethylene glycol, 850 parts of ethanol, and 95 parts of xylene.

Embodiment 3

[0009] Embodiment 3: including 120 parts of 2-hydroxy-4-octyloxybenzophenone, 550 parts of polyethylene glycol, 900 parts of ethanol, and 100 parts of xylene.

[0010] During production, polyethylene glycol is first dispersed in a mixed solvent of ethanol and xylene, an ultraviolet light absorber 2-hydroxyl-4-octyloxybenzophenone is added, and the ultraviolet light shielding coating is obtained by mixing evenly.

[0011] In summary, the present invention can pass through visible light, but can shield ultraviolet light through the ultraviolet light absorber.

Abstract

The application discloses an ultraviolet shielding coating comprising the following components in parts by weight: 80-120 parts of 2-hydroxy-4-octyloxybenzophenone, 450-550 parts of polyethylene glycol, 800-900 parts of ethanol and 90-100 parts of dimethylbenzene. Therefore, although the ultraviolet shielding coating disclosed by the invention can be penetrated by visible light, the effect of shielding ultraviolet light can be generated by virtue of an ultraviolet absorbent.

Description

technical field [0001] The invention relates to chemical coatings, in particular to an ultraviolet light shielding coating. Background technique [0002] The current UV shielding coatings are various, but there are still some problems in different degrees. The existing UV shielding coatings have a large shrinkage rate after photocuring and shrinkage stress, resulting in brittleness of the coating film, adhesion and durability. Poor impact force, poor flexibility and low hardness of the coating film, no corrosion resistance, easy yellowing and aging. Contents of the invention [0003] The object of the present invention is to provide an ultraviolet light shielding coating, which can solve one or more of the above-mentioned problems in the prior art. [0004] According to one aspect of the present invention, there is provided an ultraviolet light shielding coating, comprising 80-120 parts of 2-hydroxy-4-octyloxybenzophenone, 450-550 parts of polyethylene glycol, 800-900 par...
