Abstract

The invention discloses an industrial heat-resistant silane modified polyether sealant in the technical field of adhesives. The industrial heat-resistant silane modified polyether sealant is prepared from the following raw materials in parts by weight: 80-100 parts of silane modified polyether, 50-80 parts of a plasticizer, 160-200 parts of a filler, 0.1-10 parts of a thixotropic agent, 1-2 parts of an ultraviolet light absorber, 1-2 parts of a light stabilizer, 4-7 parts of a water remover, 3-6 parts of a coupling agent and 1-2 parts of a catalyst. According to the silane modified polyether sealant, a polysiloxane chain segment is introduced, so that the heat resistance of the sealant can be effectively improved, the finishing property is not influenced, and the silane modified polyether sealant prepared by adopting the formula and the method can be widely applied to the industrial fields of rail transit, automobile manufacturing, containers and the like.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to an industrial heat-resistant silane-modified polyether sealant and a preparation method thereof. Background technique [0002] At present, the three most common sealants on the market are: polysulfide type, silicone type and polyurethane type. Polysulfide type sealants are increasingly being eliminated due to many problems such as slow curing at low temperature and poor durability. The terminal NCO group of polyurethane sealant is sensitive to moisture, and has poor storage stability. At the same time, it is easy to produce pores and slow curing speed; silicone sealant does not have paintability, and the adhesive layer is easy to oil out. Silane-modified polyether sealant, also known as MS glue, can combine the advantages of polyurethane-type and silicone-type sealants, exhibit excellent adhesion and paintability, and exhibit good environmental friendliness; solvent...
