Abstract

The invention provides a sandstone hardening and brightening agent and a preparation method thereof. The agent permeates, reacts and forms a film on the sandstone surface so as to quickly plug the gaps on the rough sandstone surface and form a compact, transparent and hard protective film on the surface, thereby greatly overcoming the severe defects of large gaps, high differentiation tendency and the like in the sandstone.

Description

Technical field: [0001] The invention relates to a sandstone hardening brightener and a preparation method thereof, belonging to the field of building materials. Background technique: [0002] Due to its strong naturalness and low radioactivity, sandstone has a variety of pure natural colors such as red, yellow, and purple, and various gorgeous patterns. It is an ideal building decoration material. However, due to the sandstone's own defects such as large porosity, high water absorption rate, easy differentiation, low compressive strength, poor wear resistance and moisture absorption resistance, it is easy to cause various stone lesions and limit the scope of application of sandstone. Therefore, in order to overcome the inherent defects of sandstone, improve its performance, and make sandstone more widely used in the field of architectural decoration, it is of great practical application value. The present invention adopts the principles of penetration, reaction and film fo...
