Abstract

The invention relates to an internally-reinforced composite butyl self-adhesive ethylene-propylene rubber waterproof coiled material and a production method thereof. The internally-reinforced composite butyl self-adhesive ethylene-propylene rubber waterproof coiled material is formed by sequentially and mutually overlapping and compounding a basic layer, a self-adhesive layer and a sticking prevention layer; the basic layer is prepared by compounding a surface layer and a foundation layer on two sides of a reinforcement layer or compounding the surface layer above the reinforcement layer; thesurface layer and the foundation layer are both ethylene-propylene rubber layers; the reinforcement layer is an expanded metal net or fiber grid cloth; the self-adhesive layer is a butyl self-adhesiverubber layer or a butyl hot melt adhesive; the sticking prevention layer is a PE isolating membrane. According to the internally-reinforced composite butyl self-adhesive ethylene-propylene rubber waterproof coiled material disclosed by the invention, node parts of thin parts are permanently sealed to a maximum extent, so that a waterproofing effect of an overall waterproof layer is greatly improved and the durability life of the overall waterproof layer is greatly prolonged, and the problem that the node parts of the thin parts of the waterproof layer cannot be handled well by adopting an existing ethylene-propylene-diene monomer rubber waterproof coiled material is solved.

Description

1. Technical field [0001] The invention relates to the field of building waterproof materials, in particular to an internally reinforced composite butyl self-adhesive ethylene-propylene rubber waterproof coiled material and a production method thereof. 2. Background technology [0002] At present, the single-layer waterproof material used on building roofs should have the best comprehensive performance in the relatively mature and internationally recognized EPDM waterproof membrane, but the non-polar structure of EPDM also leads to its Self-adhesive and mutual adhesion are poor. During the construction of the coiled material, for the joints such as the yin and yang corners, due to the influence of construction and its own factors such as the plasticity of the coiled material and the cohesive force of the material, the coiled material is not easy to fix and stick to these parts, especially It is used in some areas with large temperature differences and roof materials with lar...
