Problems solved by technology

During the construction process on the construction site, it is unavoidable that construction tools, building materials and tools for cutting coils will fall on the waterproof membrane. However, the existing waterproof membranes are weak on the sharp parts of sharp tools due to their weak toughness. After contact with the waterproof membrane, the surface layer of the waterproof membrane will be damaged, which will weaken the waterproof function of the local waterproof membrane

Abstract

The invention discloses a reaction ethylene-propylene-diene monomer butyl self-adhesive waterproof coiled material and a preparation method thereof. The reaction ethylene-propylene-diene monomer butylself-adhesive waterproof coiled material comprises an ethylene-propylene-diene monomer waterproof layer, a self-adhesive reactive butyl rubber layer is arranged at the bottom end of the ethylene-propylene-diene monomer waterproof layer, and a polyethylene waterproof adhesive layer isolating membrane is arranged at the bottom end of the self-adhesive reactive butyl rubber layer; wherein the ethylene propylene diene monomer waterproof layer is prepared from the following raw materials in parts by mass: 100-200 parts of ethylene propylene diene monomer, 50-100 parts of polyurethane, 10-20 partsof a mixed polyether, 20-30 parts of high-wear-resistant carbon black, 5-10 parts of zinc oxide, 10-15 parts of stearic acid and 5-10 parts of an accelerant. The ethylene-propylene-diene monomer butylself-adhesive waterproof coiled material has the beneficial effects that the toughness of the ethylene-propylene-diene monomer butyl self-adhesive waterproof coiled material is improved, and the situation that after construction tools, building materials and tools for cutting the coiled material fall off, the local waterproof coiled material is damaged is avoided.

Description

technical field [0001] The present invention relates to EPDM self-adhesive waterproof roll material, in particular to a reactive EPB butyl self-adhesive waterproof roll material and a preparation method thereof. Background technique [0002] EPDM rubber is a copolymer of ethylene, propylene and a small amount of non-conjugated dienes. It is a kind of ethylene-propylene rubber because its main chain is composed of chemically stable saturated hydrocarbons and only contains unsaturated in the side chain. Double bond, so it has excellent ozone resistance, heat resistance, weather resistance and other aging resistance, and can be widely used in automotive parts, waterproof materials for construction, wire and cable sheaths, heat-resistant hoses, tapes, automotive seals and other fields. Butyl rubber is a kind of synthetic rubber, which is synthesized from isobutylene and a small amount of isoprene. Generally used to make tires. In the field of building waterproofing, butyl rubb...
