Technical Field

The invention relates to the technical field of stone protective agents, in particular to a maintenance-free and cracking-resistant stone protective agent for home decoration marble.

Background

Marble originally refers to white limestone with black patterns produced in Yunnan province, the section of the limestone can form a natural wash painting, marble with formed patterns is often selected in ancient times to be used for making a screen or an inlaid picture, and the name of marble is gradually developed to refer to all limestone with patterns of various colors and used as building decoration materials. White marble is generally called white marble, but it is also called marble for translating western-style statues. The marble is very beautiful after polishing. It is mainly used for processing various shapes and plates, and can be used as wall surface, floor, table and column of building, and also can be used as material for memorial building, such as stele, tower and statue. The marble can also be carved into practical artworks such as art and art works, stationery, lamps and utensils.

Definition of stone protective agent stone protection is that some protective agents are brushed, sprayed, painted, rolled, sprayed, soaked and the like, so that the stone protective agent is uniformly distributed on the surface of stone or permeates into the stone to form protection, and the stone has the functions of water resistance, pollution resistance, acid and alkali resistance, ageing resistance, freeze thawing resistance, biological corrosion resistance and the like, thereby achieving the effects of prolonging the service life of the stone and improving the decorative performance of the stone.
