Embodiment Construction

[0025]In parts by weight, weigh 45 to 50 parts of deionized water, 3 to 5 parts of borax, 1 to 2 parts of trioctyl phosphate and 2 to 5 parts of zinc nitrate in a beaker, stir and mix and place at 200 to Ultrasonic disperse at 300W for 10-15min, continue to stir and add dropwise 5% sodium hydroxide solution until the pH reaches 8.0, keep the reaction at 65-75°C for 6-8h, obtain the reaction solution and filter it, collect the lower precipitate and use deionized Rinse with water for 3-5 times, vacuum freeze-dry and grind through a 1000-mesh sieve to obtain modified nanoparticles; in parts by weight, weigh 45-50 parts of deionized water, 10-15 parts of 500-mesh aluminum powder and 10-15 parts of Put 15 parts of 1% hydrochloric acid in an Erlenmeyer flask, stir and mix them and place them at 100-110°C for 20-24 hours, keep them under reflux for 20-24 hours, let them cool down to room temperature to obtain a sol solution, and add the compound solution dropwise at a mass ratio of 1:...

Abstract

The invention relates to a method for preparing a high-permeability stone protection agent material, and belongs to the technical field of stone protection. N-octyltriethoxysilane, propyltriethoxysilane and oligomeric hydroxy silicone oil mixed silane is used as a waterproof active component, and is polymerized by an aqueous phase emulsion in an open reaction system at an ordinary stirring speed to prepare a well-dispersed colloidal-stable silicone emulsion, the emulsion is compounded with a sol material to effectively penetrate into the inner pores of stone, and pore filling and coating makeeffective coating layers effectively formed on the stone surface and in the stone pores, so the protective effect of the coating protection agent material is further improved; and the sol is filled with nanoparticles to achieve the modification function, so the marble matrix structure is reinforced, the weather resistance is improved, infiltration of moisture and corrosion of other harmful substances are prevented, and cracks caused by freezing and thawing are prevented, thereby the wear resistance, the water resistance and the dust resistance are significantly improved.

Description

technical field [0001] The invention relates to a preparation method of a high-permeability stone protective agent material, which belongs to the technical field of stone protection. Background technique [0002] Natural stone is one of the oldest building materials. Due to its rich resources, high compressive strength, durability, wear resistance and good decoration, it is widely used in building decoration materials, masonry materials such as foundations and walls, and aggregates of concrete. Stone can be classified in various ways, but basically according to different geological formation conditions, it can usually be divided into three categories, namely igneous rock, sedimentary rock and metamorphic rock. Magmatic rock, also known as igneous rock, is formed by the change of the earth's crust, and the molten magma rises from the interior of the earth's crust and cools down. Magmatic rocks are divided into plutonic rocks, epitonic rocks, extrusive rocks and volcanic roc...
