Problems solved by technology

After the silicone glue turns yellow, it is extremely unsightly, and even affects the visual harmony of the whole building
[0004] Although the silicone rubber sealing strip is compatible with silicone glue and will not cause the silicone glue to turn yellow, it has high cost, poor strength and tear performance, and short service life
Moreover, due to the production limitations of silicone rubber sealing strips, it cannot be mass-produced

Embodiment Construction

[0040] 1. According to the ratio, take 100 parts by mass of EPDM rubber, 50 parts by mass of paraffin oil (less than 0.5% aromatic content), 120 parts by mass of carbon black (N550), 0.5 parts by mass of sulfur, BZ (dibutyl dithio Zinc carbamate) 1.8 parts by mass, M (mercaptobenzothiazole) 1.2 parts by mass, TMTD (tetramethylthiuram disulfide) 0.5 parts by mass, PZ (zinc dimethyl dithiocarbamate) 0.5 parts by mass 2 parts by mass of DTDM (dimorpholine disulfide), mixed by an internal mixer to make a mixed rubber for later use.

[0041] 2. After the mixed rubber is parked, put it into the screw extruder, put it into the mouth shape required by the production and extrude it, and then shape it after high temperature vulcanization.

Abstract

The invention relates to an ethylene propylene diene monomer rubber sealing strip compatible with a silicone adhesive. The sealing strip is prepared by compounding the following raw materials: 100 mass parts of ethylene propylene diene monomer rubber, 45 to 55 mass parts of paroline with the arene content of less than 0.5 percent, 100 to 120 mass parts of carbon black, 0.3 to 0.5 part of sulphur, 1.5 to 2 parts of zinc dibutyldithiocarbamate, 1.2 to 1.5 parts of benzothiazolethiol, 0.3 to 0.5 part of tetramethyl thiuram disulfide, 0.5 to 0.6 part of zinc dimethyldithiocarbamate, and 1.5 to 2 parts of dithiodimorpholine. The ethylene propylene diene monomer rubber sealing strip compatible with the silicone adhesive is compatible with the silicone adhesive, has low cost, high intensity and tearing property, and long service life and can be produced on a large scale.

Description

technical field [0001] The invention relates to a rubber sealing strip. In particular, it relates to a EPDM sealing strip used for sealing building doors, windows and curtain walls. It belongs to the technical field of building seals. Background technique [0002] When installing glass doors, windows and curtain walls, rubber sealing strips need to be embedded around them to play the role of sound insulation, waterproof and sealing. When the rubber sealing strip is installed, it needs to be fixed with white or translucent silicone glue. Before the present invention was made, generally adopt ethylene propylene rubber sealing strip or silicon rubber sealing strip to realize the sealing of doors and windows in the past. These two kinds of rubber strips mainly have the following deficiencies: [0003] EPDM rubber sealing strips are incompatible with silicone rubber. Due to long-term exposure to sunlight, under the action of ultraviolet rays in sunlight, silicone rubber will ...
