Sealing adhesive strip for ribbed self-adhesive glass and manufacturing method thereof

Abstract

The invention relates to a sealing adhesive strip for ribbed self-adhesive glass and a manufacturing method thereof. The sealing adhesive strip for the ribbed self-adhesive glass belongs to an elastic edge strip for sealing the edge of the glass of doors and windows, and comprises a built-in rubber strip rib and a butyl rubber sealant layer coated on the surface of the built-in rubber strip rib, wherein the butyl rubber sealant layer comprises the following raw material components in parts by weight: 30 parts of cross-linking butyl rubber, 5 parts of ethylene propylene diene rubber, 20 parts of polyisobutene of which the molecular weight is 40000, 40 parts of polyisobutene of which the molecular weight is 2400, 20 parts of amorphous state a-olefin copolymer, 30 parts of tackifying resin, 100 parts of filler, 5 parts of silicon dioxide, 10 parts of carbon black, 0.2 part of benzoquinone dioxime and 0.1 part of lead dioxide. The manufacturing method comprises the following steps: (1) banburying and kneading butyl rubber sealant; (2) coating and extruding. The invention provides the sealing adhesive strip for the ribbed self-adhesive glass, which has good low-temperature elasticity, simple construction process and low cost and is beneficial to environmental protection, a manufacturing method thereof. The sealing adhesive strip for the ribbed self-adhesive glass provided by the invention is suitable for sealing the glass of building doors and windows, curtain walls and automobile and ship doors and windows and the frame section bar of the glass.

Description

technical field [0001] The invention relates to a self-adhesive glass sealing strip with ribs and a manufacturing method thereof. It belongs to the elastic edge strip used for sealing the edge of door and window glass. Background technique [0002] Doors, windows and curtain walls are mainly composed of aluminum alloy or steel-plastic structure, insulating glass and low-E glass or ordinary glass, and the sealing of doors, windows and curtain wall frames and glass accounts for a large proportion (15%) of the entire building energy saving. In the stage of sealing doors, windows and curtain walls, structural adhesives and sealing strips are mainly used together or alone, which puts forward high requirements on the tightness and aging resistance of sealants and strips, because poor sealing directly affects Building energy-saving technical indicators, and poor aging resistance will directly affect the cost of building energy-saving use, because the service life of doors, windows...

Problems solved by technology

[0007] 2. Although EPDM strips and other elastomer strips have good elasticity, they have poor air-tightness and water-tightness, poor followability, and are not resistant to aging. In order to maintain good elasticity, a large amount of plasticizer needs to be added, and it will precipitate out after a long time , easy to pollute the environment

[0008] 3. Although the use of silicone structural adhesive seals has good elasticity and bonding fastness, if all of them are used for sealing, the appearance will be untidy, and the water-tightness and air-tightness of silicone structural adhesives are poor, the construction process is complicated, and the cost is high. low efficiency

[0009] 4. Although the EVA tape or PE foam tape coated with pressure-sensitive adhesive is convenient and clean, it only plays the role of fixing the glass and the frame, and has no sealing effect
