Problems solved by technology

However, the waterproof membrane still has certain deficiencies. For example, the waterproof membrane has poor heat resistance and flame retardancy. Only by accelerating the self-adhesive process and improving the viscosity can the use efficiency of the waterproof membrane be guaranteed. The service life and waterproof effect will be affected to a certain extent

preparation example Construction

[0087] According to another embodiment of the present invention, as figure 2 As shown, a preparation method of a polymer rubber waterproofing membrane based on a TPV main material is also provided, and the preparation method comprises the following steps:

[0088] S1, use an internal mixer to prepare and shape the TPV waterproof layer 4;

[0089] Wherein, step S1 includes:

[0090] S11, preparing modified TPV elastomer;

[0091] At present, two methods are often used for the preparation of modified TPV elastomers, namely one-step method and two-step method.

[0092] The equipment usually used in the one-step method is a twin-screw extruder, which completes the dynamic vulcanization process inside the screw through the method of segmented feeding. Because the twin-screw extruder can provide a strong shear force, the blend can be well mixed, and at the same time, the residence time can be precisely set between each stage. On the basis of ensuring continuous production, the ...

Abstract

The invention discloses a polymer rubber waterproof roll based on a TPV main material and a preparation method. The polymer rubber waterproof roll comprises a self-adhesion base layer, a heat preservation and insulation layer, a sound insulation layer, a fiber core wire layer, a TPV waterproof layer and an isolation protection layer which are sequentially connected from bottom to top. A plurality of anti-wrinkling holes which are arranged at equal intervals and distributed in a rectangular mode are formed in the top of the isolation protection layer, and the fiber core wire layer is of a grid woven structure. The modified TPV elastomer is used as a core material, so that the modified TPV elastomer has good rebound resilience, dimensional stability, high impact resistance and high mechanical strength; meanwhile, complex and tedious vulcanization procedures are not needed, processing can be directly carried out like common thermoplastic plastics, the technological procedures are simplified, and the forming period is shortened; and in the aspect of sustainable utilization, processing residual materials or waste materials can be recycled for reprocessing treatment, so that the material has a good regeneration recycling characteristic, and has positive significance on environmental protection while the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of rubber waterproof rolls, in particular to a polymer rubber waterproof roll based on a TPV main material and a preparation method. Background technique [0002] Waterproof materials play an important role in building construction. In the construction of roads, bridges, roofs or buildings that need waterproofing, a large amount of waterproofing materials need to be laid to prevent leakage. The quality and service life of waterproof materials directly affect the quality of the entire construction project. [0003] At present, waterproof materials are usually divided into five categories: waterproof membranes, waterproof coatings, plugging water materials, rigid waterproof and sealing materials. For large-area waterproof construction, waterproofing membrane is the first choice material. [0004] The traditional asphalt-based waterproofing membranes are all waterproofing membranes made of polymer modified bi...
