preparation example Construction

[0046] The preparation method of the hydrophobic titanium dioxide in the anti-fog layer 13 is as follows:

[0047] Add an alcoholic aqueous solution containing an aminosilane coupling agent to the titanium dioxide, stir for 45 minutes, then wash with water; then use a fluorine-containing silane coupling agent to treat for 1.5-2 hours, and dry to obtain hydrophobic titanium dioxide.

[0048] The anti-fog PC board of the invention has good hydrophobicity, blister resistance and alcohol wiping resistance.

[0049] The hydrophobic titanium dioxide of the present invention is a specially modified filler with good hydrophobicity; the organosilicon acrylic polymer emulsion contains a highly hydrophobic organosilicon structure, and the organosilicon structure is hydrolyzed in the anti-fog layer to strengthen The stability of the anti-fog layer; after the anti-fog layer raw materials in the present invention are blended, the hydrophobic titanium dioxide and the organic silicon acrylic ...

Abstract

The invention relates-an anti-fog PC board, the PC board sequentially comprises a base body, a bonding layer, a strengthening layer and an anti-fog layer, and the anti-fog layer is prepared from the following raw materials in parts by weight: 20-30 parts of anti-fogging liquid; 3-8 parts by weight of hydrophobic titanium dioxide; 20-30 parts by weight of an organosilicon acrylic polymer emulsion; and 15-20 parts by weight of deionized water. The invention also relates to a preparation method of the PC board. The anti-fog PC board formed by the invention has better hydrophobicity, water soaking resistance and alcohol wiping resistance.

Description

technical field [0001] The invention relates to the technical field of PC boards, in particular to an anti-fog PC board and a preparation method thereof. Background technique [0002] PC board, also known as polycarbonate board, is a plastic building material commonly used in the world. It has advantages that other building decoration materials (such as glass, plexiglass, etc.) cannot match; Problems such as immersion cause damage, which affects its service life. At the same time, it is widely used in industries such as medical protection and sports lenses, but the surface is not anti-fog, which makes it unable to meet actual needs. [0003] Therefore, it is necessary to improve the prior art to overcome the defects in the prior art. Contents of the invention [0004] In order to overcome the deficiencies in the prior art, the first object of the present invention is to provide a kind of anti-fog PC board, described PC board comprises matrix, bonding layer, strengthening...
