Abstract

The invention provides a preparation method of anti-ultraviolet modified silane polyether adhesive. The preparation method comprises the following steps: (1) stirring and mixing the following materials in parts by mass: 10 to 20 parts of a plasticizer, 60 to 70 parts of powder, and 1 to 2 parts of a silane coupling agent in a reaction kettle, and performing vacuum drying; (2) adding 5 to 10 partsof an anti-ultraviolet absorbent, 0.1 to 0.5 part of an antioxidant, 0.1 to 0.5 part of a light stabilizer, and 1 to 3 parts of a silane coupling agent, performing normal pressure heating, and cooling; (3) adding 10 to 30 parts of modified silane polyether resin 30000T, and 1 to 5 parts of fumed silica, and performing vacuum stirring; (4) adding the surplus of the silane coupling agent, and 0.1 to0.3 part of a catalyst, and performing vacuum stirring and pressure maintaining, so as to obtain the anti-ultraviolet modified silane polyether adhesive. The anti-ultraviolet modified silane polyether adhesive formed through the method has excellent bonding strength and a durable anti-ultraviolet function.

Description

technical field [0001] The invention belongs to the technical field of sealants, and relates to a preparation method of an anti-ultraviolet 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, tolu...
