Problems solved by technology

But its glue-coated reinforcing layer is made of glue-coated non-woven fabric or glass fiber. Although non-woven fabric or glass fiber has a certain strengthening effect, it must solve the bonding problem between non-woven fabric or glass fiber and rubber. Glue is pre-applied on the surface of non-woven fabric or glass fiber to increase the cohesiveness. For this reason, the gluing process of non-woven fabric or glass fiber is added, and at the same time, it may cause glue leakage due to careless operation, so that this type of The delamination of the rubber waterproof sheet layer and the self-adhesive rubber layer of the composite membrane affects the quality of the project
Moreover, this type of waterproof sheet has poor plasticity, and it is not easy to fix and fit at the corners.

[0038] Preparation of vulcanized rubber waterproof sheet

[0039] Each component is based on EPDM rubber, and is formulated according to the following weight ratio

[0040]

[0041]

[0042] Mix the EPDM rubber, zinc oxide, naphthenic oil, and high wear-resistant carbon black in the above ratio, and mix them with an internal mixer at 100-120°C. After about 15-20 minutes, discharge at a temperature of 80-90°C. , park and cool, filter the rubber, and add accelerator M and accelerator TT on the open rubber mixer at a temperature of 80-90 ° C, and mix evenly with sulfur. After parking for 24 hours, it becomes a mixed rubber.

[0043] Extrude the above compounded rubber from a cold-feed extruder, and vulcanize it through a continuous vulcanization box at a vulcanization temperature of 180°C and a vulcanization speed of 4m / min to form a vulcanized rubber sheet.

[0044] Preparation of unvulcanized rubber strips:

[0045] According to the following weight ratio ingredients

Abstract

The invention discloses a method for preparing a rubber-metal composite waterproof sheet, and relates to a method for preparing a rubber composite waterproof sheet. The method has a simple manufacturing process; and the prepared product has high strength, self-healing property and high plasticity, and the construction process is simple without adhesive. The method is characterized by comprising the following steps of: laminating and gluing a 2-8-mesh aluminum mesh and a vulcanized rubber sheet to obtain a laminated sheet of the 2-8-mesh aluminum mesh and the vulcanized rubber sheet; laminating a non-vulcanized rubber sheet with the laminated sheet, and compounding into a composite sheet of the non-vulcanized rubber sheet, the 2-8-mesh aluminum mesh and the vulcanized rubber sheet through a press roll; and compounding an isolating membrane on the composite sheet, laminating and gluing, and winding into a reel on a winding roller to obtain the rubber-metal composite waterproof sheet integrating the vulcanized rubber sheet, the aluminum mesh, the non-vulcanized rubber sheet, and the isolating membrane. The method is used for waterproof sheets in constructional engineering.

Description

Technical field: [0001] The invention relates to a method for preparing a rubber composite waterproof sheet, in particular to a method for processing a rubber-metal composite waterproof sheet. Background technique: [0002] At present, the rubber waterproof sheets used in the construction market mainly include vulcanized rubber waterproof sheets, non-vulcanized rubber waterproof sheets and self-adhesive rubber waterproof sheets. The vulcanized rubber waterproof sheet has good physical and mechanical properties, while the non-vulcanized rubber waterproof sheet and self-adhesive rubber waterproof sheet have good self-healing and self-adhesive properties. Sheet. [0003] The traditional vulcanized rubber waterproof sheet has strict requirements on the base surface during construction, especially the EPDM rubber waterproof sheet must be matched with materials to ensure the bonding effect. At the same time, if the construction is improper, it is easy to bulge on the material su...
