Embodiment Construction

[0013] A hot-melt butyl sealant for insulating glass containing alkyl ketene dimer, prepared from the following components by weight (kg):

[0014] Butyl rubber 10, polyisobutylene 30, binary ethylene propylene rubber 5, alkyl ketene dimer 2, silane coupling agent A-151 0.5, furfuryl alcohol resin 5, styrene-maleic anhydride copolymer 0.5, o-phthalic Dibutyl diformate 3, heavy calcium carbonate 10, erucamide 1, mica powder 5.

[0015] A preparation method for a hot-melt butyl sealant for hollow glass containing alkyl ketene dimer, comprising the following steps:

[0016] (1) Weigh raw materials by weight, first mix furfuryl alcohol resin, alkyl ketene dimer and dibutyl phthalate at 80°C for 0.5h, then add silane coupling agent A-151 and stir at 100°C for 10min , to obtain modified furfuryl alcohol resin adhesive after cooling;

[0017] (2) First, blend butyl rubber, polyisobutylene, binary ethylene propylene rubber, and styrene-maleic anhydride copolymer evenly at high speed...

Abstract

The invention discloses hot-melt butyl sealant containing alkyl ketene dimer for hollow glass. The hot-melt butyl sealant is prepared from the following raw materials in parts by weight: 10-20 parts of butyl rubber, 30-40 parts of polyisobutene, 5-10 parts of ethylene-propylene rubber, 2-4 parts of alkyl ketene dimer, 0.5-1 part of a silane coupling agent A-151, 5-10 parts of furfuran resin, 0.5-1 part of styrene-maleic anhydride copolymer, 3-5 parts of dibutyl phthalate, 10-15 parts of heavy calcium carbonate, 1-2 parts of erucyl amide and 5-10 parts of mica powder. The hot-melt butyl sealant has excellent deformation resistance, high strength, high adhesive property, high water resistance and corrosion resistance, good comprehensive property and strong practicability.

Description

technical field [0001] The invention relates to the technical field of sealant, in particular to a hot-melt butyl sealant for hollow glass containing alkyl ketene dimer and a preparation method thereof. Background technique [0002] Insulating glass integrates excellent properties such as heat insulation, sound insulation, and lighting. It is an efficient energy-saving product and is widely used in glass curtain walls, automobiles, transportation, and aircraft. As insulating glass enters the field of new buildings in large quantities, people's quality requirements for insulating glass are also getting higher and higher. Insulating glass with long sealing life can not only bring good economic benefits, but also have stronger market competitiveness. Butyl sealant has extremely low water vapor transmission rate and good sealing effect. It is used as the first insulating glass sealant and plays a key role in the comprehensive quality performance of insulating glass products. ...
