Abstract

The invention relates to a sealing material and particularly relates to a silicone sealant for a stone curtain wall. The silicone sealant is prepared from the following raw materials: a dimethyl siloxane polymer, (3-methyl butoxy)acetic acid-allyl alcohol ester, 2-(1,3-dimethyl-2,6-dioxo-2,3,6,7-tetrahydro-1H-purine-7-yl)acetic acid, hexamethyldisiloxane, 4-hydroxy-3-methoxy acetophenone and the like. The silicone sealant for the stone curtain wall has the advantages of good adhesive property, high flame retardance level and relatively long shelf life, facilitates long-time storage and is easy and convenient to construct with short time; and the preparation method is simple and easy to learn, the machine is convenient to operate, and large-scale production in a plant is promoted.

Description

technical field [0001] The invention relates to a sealing material, in particular to a silicone sealant for a stone curtain wall. Background technique [0002] As a high-grade building decoration material, stone is widely used in indoor and outdoor decoration design, curtain wall decoration and public facilities construction. At present, the common stone materials on the market are mainly divided into natural stone and artificial stone. Natural stone is divided into two types: slate and granite according to the quality of physical and chemical properties. Artificial stone is divided into terrazzo and synthetic stone according to the process. Terrazzo is made by forging and pressing of cement, concrete and other raw materials; synthetic stone is made of natural stone gravel as raw material, plus adhesives, etc., after pressing and polishing. The latter two are made artificially, so the strength is not as high as natural stone. Stone is a high-end product of building dec...
