Problems solved by technology

[0003] 1. The KH550 (γ-aminopropyltriethoxysilane) in the prior art is relatively active when used alone, and has good adhesion to the substrate, but has the disadvantages of fast reaction and unstable storage in the process , KH560 (γ-glycidyl etheroxypropyl trimethoxysilane), its epoxy group has the advantage of stable process performance, but it has poor adhesion to the substrate
[0004] 2. At present, most of the silicone adhesives produced in China are ketone oxime type, which will release more than 3% of butanone oxime during the curing process. Long-term use has certain harm to the human body.

Abstract

The invention relates to a two-component odor-removing hollow glass silicone sealing glue, which is prepared by mixing a component A and a component B. In the prior art, auxiliary agents such as KH550, KH560, KH602 and KH792 and a glue are mixed so as to be used. According to the present invention, the technology is different from the prior art, and comprises: carrying out mixing cross-linking onthe four components such as KH550, KH560, KH602 and KH792 so as to completely perform cross-linking, and dibutyltin dilaurate is added to the component B, such that the product of the present invention has advantages of good odor removing effect and strong bonding strength, wherein the detection results show that the content of methanol, ethanol and other small molecule alcohol substances is about1%, and the bonding strength can achieve 0.86 MPa while the film plating glass bonding strength of the existing ketoxime type silicone glue is only 0.46 MPa; and the two-component odor-removing hollow glass silicone sealing glue is economical, environmentally friendly, safe and effective, and is suitable for promotion, production and use.

Description

technical field [0001] The invention belongs to the field of silicone sealant processing, and relates to a two-component silicone sealant, in particular to a two-component odor-removing hollow glass silicone sealant. Background technique [0002] Two-component silicone adhesive sealant has excellent aging resistance, water resistance, oil resistance, heat resistance, chemical resistance, and has the advantages of fast and deep curing. It has a wide range of applications, but commercially available coupling agents (adhesion promoters) are only used in silicone two-component sealants, and have some disadvantages in application: [0003] 1. The KH550 (γ-aminopropyltriethoxysilane) in the prior art is relatively active when used alone, and has good adhesion to the substrate, but has the disadvantages of fast reaction and unstable storage in the process , KH560 (γ-glycidyl ether oxypropyltrimethoxysilane), its epoxy group has the advantage of stable process performance, but it h...
