Problems solved by technology

[0005] However, the silane-modified polyether sealant itself has poor flame retardancy. Even if fillers such as silica and calcium carbonate are added, it will continue to burn once it is ignited after contact with the flame.

Abstract

The invention provides a flame-retardant modified silane polyether adhesive. The flame-retardant modified silane polyether adhesive disclosed by the invention is prepared from the following raw materials calculated in parts by weight: 10 to 30 parts of modified silane polyether resin 30000 T, 1 to 5 parts of fumed silica, 1 to 5 parts of a silane coupling agent, 1 to 10 parts of a flame-retardantcomplex additive, 60 to 70 parts of powder, 0.1 to 0.5 part of a light stabilizer, 10 to 20 parts of a plasticizer, 0.1 to 0.3 part of a catalyst, and 0.1 to 0.5 part of an oxidant. The flame-retardant modified silane polyether adhesive disclosed by the invention is high in bond strength, and better in elongation and tensile strength and good in flame retardancy, wherein the bond strength is morethan 1.4 MPa, the elongation is more than 550%, the tensile strength is more than 3.6 MPa, and the flame retardancy can reach the levels V-1 and V-0.

Description

technical field [0001] The invention belongs to the technical field of sealants, and relates to a flame-retardant modified silane polyether glue. Background technique [0002] The full name of MS glue is modified silane polyether glue, which is a new generation of building sealant developed after polysulfide glue, silicone glue and polyurethane glue. It is mainly used in the fields of bonding, caulking, jointing, sealing, waterproofing, reinforcement, etc. in construction engineering and decoration; Applications in industrial fields are also expanding. [0003] Traditional polyurethane sealants are limited in many application fields because they contain free isocyanate and are prone to form bubbles during curing. At present, domestic construction sealants are mainly made of silicone glue. Compared with them, MS glue has more and more prominent advantages: 1. Excellent environmental protection performance: no solvent addition, no formaldehyde, toluene, xylene, etc. in the p...
