Problems solved by technology

The mechanical properties of some butyl hot-melt adhesives on the market are not up to the standard. Some of them have low bonding strength, poor initial adhesion to aluminum frames, easy to slip or decline in bonding performance with glass after a period of use, blocking The phenomenon that the effect becomes worse, even occurs with the glass falling off

Abstract

The invention discloses a butyl hot melt adhesive and a preparation method thereof. The preparation method comprises the following steps that in a high temperature kneader, the temperature is set at 130 DEG C-150 DEG C, 180-600 parts by weight of polyisobutene, 100 parts by weight of butyl rubber and 30-120 parts by weight of tackifying resin are firstly added into the kneader, the temperature is increased to 110 DEG C-130 DEG C, and stirring is performed until the materials are uniform; 450-1000 parts by weight of packing, 0-7 parts by weight of an anti-aging agent and 1-25 parts by weight of a softening agent are sequentially added, vacuumizing and stirring are performed for 0.5-2.5 hours, 20-100 parts by weight of the retained polyisobutene is added, vacuumizing and continuous stirring are performed for 0.5-2 hours, and the butyl hot melt adhesive is prepared. The butyl hot melt adhesive prepared through the method is excellent in anti-ultraviolet property and easy to construct, has the excellent adhesive property on hollow glass materials and aluminum alloy strips and can not only meet usage of hollow glass, but also be applied to the fields such as photovoltaic backboard adhesion.

Description

Technical field [0001] The invention relates to a butyl hot melt adhesive and a preparation method thereof, in particular to a butyl hot melt adhesive for hollow glass assembly and a preparation method thereof. Background technique [0002] As an important component of energy-saving buildings, insulating glass is widely used in building doors and windows, glass curtain walls, and has good sound insulation, heat insulation, frost resistance, safety and heat preservation properties. In order to ensure the quality of insulating glass and ensure its energy-saving and sound insulation effects, most manufacturers at home and abroad now adopt double-sealing methods to ensure its excellent performance. For the sealing of insulating glass, the current preparation process usually adopts double sealing, and the first sealing adopts butyl hot melt adhesive, which mainly plays the role of sealing and initial adhesion; the second sealing is sealed by polysulfide or silicone Finished by glue, ...
