Abstract

The invention discloses a stone crystal surface agent. The stone crystal surface agent comprises 8-20 wt% of an abrasive, 2-5 wt% of a filler, 10-18 wt% of a crystallization hardener, 1-3 wt% of a modifier, 0.5-3 wt% of an acidity adjuster, 2-5 wt% of a dispersant, 0.5-3 wt% of a soluble calcium salt, and the balance of water. The filler aerosil facilitates the improvement of the activity and thefilling of holes or apertures of stones after being sheared, and the sheared aerosil and fluosilicate generate synergistic effects to form a compact crystallization hardening protection layer. The abrasive can improve the dispersity after being modified with organosilicone in order to achieve difficult agglomeration. The soluble calcium salt added in the invention is suitable for various stones, forms a calcium fluosilicate crystallization hardened substance, and has polishing, repairing, stiffening and skid-preventing effects.

Description

technical field [0001] The invention belongs to the field of building stones, and in particular relates to the preparation technology of stone surface care agents. Background technique [0002] As a natural high-grade building decoration material, stone is widely used for its unique pattern, texture and decorative effect of returning to nature. There are more and more types of stone materials used. In addition to common granite and marble, slate, sandstone, and other non-metallic minerals are all developing into decorative stone materials. However, stone is also vulnerable to pollution and erosion, because it contains a variety of minerals and has many pores. Common stone diseases mainly include: water spots, white blooms, salting out, efflorescence, rust spots, yellowing, frost, surface corrosion, pigment pollution (including oil stains), moss growth, wear, loss of light, and powdering and peeling. [0003] Waterproof and antifouling pretreatment should be done before the...
