Abstract: Provided is a hot melt adhesive for insulating glass spacer, prepared from raw meterials comprising the following components: 1-10 parts by weight of butyl rubber, 25-50 parts by weight of a polyisobutylene mixture; 5-15 parts by weight of a tackifying resin; 1-15 parts by weight of a tackifier; 5-15 parts by weight of a polymer; 0.1-1 part by weight of a lubricant; 0.1-1 part by weight of an antioxidant; 15-50 parts by weight of a filler; 1-10 parts by weight of a water absorbent; and 5-25 parts by weight of carbon black. Compared with the prior art, in the hot melt adhesive for insulating glass spacer provided in the present disclosure, components with specific contents are used, such that relatively good overall interaction is achieved, the thixotropy of the product is good, and the adhesion to both silicone sealant and glass is excellent.

Abstract: The present disclosure provides a two-component polyurethane adhesive composition and a bonding method thereof. The two-component polyurethane adhesive composition includes A) a polyol component, and B) an isocyanate component. The polyol component includes A1) one or more polyether polyols, and the isocyanate component includes B1) a first isocyanate prepolymer, wherein the first isocyanate prepolymer is polymerized from isocyanate and a non-linear chain extender. The two-component polyurethane adhesive composition of the present disclosure has good mechanical properties, in particular, high G modulus and high elongation. The polyol component in the two-component polyurethane adhesive composition has good phase stability, and good miscibility with the isocyanate component. The two-component polyurethane adhesive composition of the present disclosure can be used for the production and manufacture of mechanical parts such as automobile components.
