Embodiment 1

[0063] This example is used to illustrate that the main material of the pre-laid polymer waterproof membrane according to the present invention adopts the formula in Table 1, and the main material of the pre-laid polymer waterproof membrane is prepared according to the following method.

[0064] The preparation method of the pre-laid polymer waterproof membrane main body material comprises the following steps:

[0065] (1) Mix the components in component A for the first time to obtain mixture I; the component A contains HDPE resin, LLDPE resin, POE resin II and color masterbatch;

[0066] The first mixing condition is: stirring at a speed of 50 rpm for 90 minutes at 90°C;

[0067] The components in the component B are mixed for the second time to obtain a mixture II; the component B contains a vinylsilane crosslinking agent, an organotin catalyst, and an initiator;

[0068] The second mixing condition is: stirring at 15 rpm for 100 min at 23°C;

[0069] (2) Extruding the mix...

Embodiment 2

[0074] This embodiment adopts the same flow process as embodiment 1 to carry out, and the difference is that in this embodiment:

[0075] The formulations and process parameters of the main materials of the pre-laid polymer waterproof membrane are different, see Table 1 for details.

[0076] The main material C2 of the pre-laid polymer waterproof membrane was prepared.

Embodiment 3

[0078] This example adopts the formula and method similar to Example 1 to prepare the main material of the pre-laid polymer waterproof membrane, the difference is: the weight of the crosslinking agent I is replaced by the crosslinking agent III, and the rest are the same as in Example 1. The main material C3 of the pre-laid polymer waterproof membrane was prepared, see Table 1 for details.

Abstract

The invention relates to the field of building waterproofing, and discloses a pre-paved macromolecular waterproof roll main body material as well as a preparation method and application thereof. The material contains a thermoplastic polyolefin layer and a high-density polyethylene layer which are laminated and compounded, the thickness of the thermoplastic polyolefin layer is less than or equal to 0.3 mm, and the thermoplastic polyolefin layer contains polyolefin elastomer resin I; the high-density polyethylene layer comprises the following components: high-density polyethylene resin, linear low-density polyethylene resin, polyolefin elastomer resin II, a vinyl silane crosslinking agent, an organic tin catalyst, an initiator and color masterbatch. According to a waterproof coiled material obtained by adopting the main body material of the pre-paved waterproof coiled material provided by the invention, the omnidirectional performance can meet the requirements in GB / T 23457-2017 pre-paved waterproof coiled material, and the heat resistance and environmental stress cracking resistance of the waterproof coiled material can be improved; meanwhile, lap joint edges can be welded through hot air, and therefore the lap joint quality of the long edges is guaranteed.

Description

technical field [0001] The invention relates to the field of building waterproofing, in particular to a main body material of a pre-laid polymer waterproof coiled material and a preparation method and application thereof. Background technique [0002] At present, although the omnidirectional performance test of high-density polyethylene pre-laid polymer waterproof membrane can meet the requirements of the national standard GB / T23457-2017 "Pre-laid waterproof membrane"; The construction quality is difficult to be guaranteed, and there is a risk of leakage. [0003] Thermoplastic polyolefin pre-laid polymer waterproof membrane, the long side lap can be welded by hot air, which can ensure the quality of the lap joint; but the pre-laid product is soft, and the puncture resistance cannot meet the national standard GB / T 23457-2017 " Pre-laid waterproof membrane" requirements. [0004] CN106543914A discloses a pre-laid polyolefin self-adhesive film waterproof sheet and a preparat...
