Problems solved by technology

In addition, when the outside temperature changes greatly, the expansion and contraction of stone and cement mortar are not the same, which will generate stress on the contact surface. Over time, the stone and cement mortar will become loose, causing the stone to fall off.

Abstract

The invention discloses a stone surface protective nano-coating, which comprises the following formula (parts by weight): 24-26 nanometer silicon dioxide; 24-26 butanol; 4.5-5.5 butyl acetate; 4.5; ethyl carbamate 2.5~3.5; methyl methacrylate 1.5~2.5; acrylic acid 14.5~15.5; butyl acrylate 5.5~6.5; hydroxyethyl acrylate 6.5~7.5; Ethylene glycol monobutyl ether 3.5~4.5. The invention also discloses a process for preparing the stone surface protective nano coating. The coating can be applied to the surface protection of various stone products such as building interior and exterior walls, stone floors, stone guardrails, and stone countertops. At room temperature, it can penetrate deeply into the surface of the stone, forming a dense, transparent, hard protective film on the surface of the stone, preventing various diseases of the stone, and improving the fullness, color saturation, texture, permeability and surface of the stone itself. Hardness and has the ability of easy cleaning and stain resistance.

Description

technical field [0001] The invention relates to a surface protective nano coating, in particular to a stone surface protective nano coating and a manufacturing process thereof. Background technique [0002] In the construction industry, stone is the most widely used building material, from ancient grottoes, stone bridges, stone towers, stone pavilions to the most commonly used modern decorative stones and various petroglyphs, statues, wall carvings and monuments, etc., stone With its strong texture, beautiful and colorful tones and magical changing stripes, it is being used more and more widely. Buildings with stone as building materials and decorations beautify people's living environment and make people fully feel the beauty and charm of nature. The surface of stone can be divided into polished surface and rough texture surface. Because stone is composed of a variety of minerals, it is very easy to react with other chemical substances, so no matter what kind of surface s...
