Abstract

The invention relates to a transparent butyl hot-melt sealant, which is prepared with the following raw materials in parts by weight: 1-20 of butyl rubber, 10-80 of polyisobutylene, 5-30 of plasticizer, 3-10 of tackifier, 3-10 of softener, 0.1-5 of stabilizer, 5-30 of filler and 0.1-5 of adhesion promoting agent. The matching use of the butyl rubber and the polyisobutylene with different molecular weights facilitates the improvement of the strength and workability of the transparent butyl hot-melt sealant. The filler is selected from fumed silica or precipitated silica, which ensures the appearance transparency of the product. Due to the addition of the stabilizer and the strict control of the production process, the appearance transparency and the physical and chemical properties of the product are enhanced. The use of the active group substituted alkoxy silane as a coupling agent improves the adhesion of the product to glass, aluminum and other substrates.

Description

technical field

[0001] The invention belongs to the technical field of sealants, and in particular relates to a transparent butyl hot-melt sealant and a preparation method thereof. Background technique

[0002] Glass curtain wall is a novel building wall decoration method, and it is a remarkable feature of the era of modern high-rise buildings. With the continuous development of science and technology and people's pursuit of beauty, glass curtain walls have been more and more widely used in various fields of architecture.
