Problems solved by technology

[0004] The rubber sealing strip used for sealing the corner structure of glass doors and windows has strong elasticity, high tensile strength, and good wear resistance, but these rubber materials have relatively insufficient corrosion resistance and aging resistance. Under the action of oxidation, the material is easy to age and deform, the strength is reduced, and the toughness is deteriorated; and cracks are formed on the surface of the sealing strip, and these cracks are easy to be further deepened under the frequent vibration and friction of the door and window opening and closing, eventually causing the sealing strip to break and be scrapped

Abstract

The invention relates to the technical field of door and window processing and in particular relates to an anti-cracking and anti-ageing sealing rubber strip for glass doors and windows. The sealing rubber strip is prepared from a stacked filling core composed of a net-shaped non-woven fabric and an outer-layer covered rubber material; the non-woven fabric and a rubber sheet are compounded in a stacking and hot pressing manner; and the rubber sheet is prepared from the following material components: nitrile butadiene rubber, natural rubber, ethylene propylene diene monomer, light calcium carbonate, a reinforcing agent, a coupling agent, an anti-ageing agent, a catalytic crosslinking agent and an activating agent, wherein the reinforcing agent is MT carbon black; the anti-ageing agent is one of an anti-ageing agent RD, an anti-ageing agent D and an anti-ageing agent 264; and the activating agent is nano zinc dioxide. The sealing rubber strip provided by the invention has strong elasticity and good sealing effect and has prominent corrosion resistance and anti-ageing performance; and the sealing rubber strip has good toughness and is unlikely to crack.

Description

technical field [0001] The invention relates to the technical field of door and window processing, in particular to an anti-crack and anti-aging sealing strip for glass doors and windows. Background technique [0002] At present, there are a large number of applications of glass door and window structures in the construction industry and machinery industry. In order to improve the sealing effect and sound insulation and windproof effect of glass door and window structures, sealing materials will be set at the corner joints of glass door and window structures. Commonly used for doors and windows Sealing materials include polyvinyl chloride, silicone rubber, thermoplastic elastomer and EPDM rubber, etc. These materials have good elasticity and can exert a good sealing effect through the extrusion deformation of the material, and will not damage the doors and windows. The structure deals physical damage. Among these materials, rubber materials are most widely used. [0003] R...
