Embodiment 1

[0071] This example is used to illustrate that the waterproof membrane prepreg composition according to the present invention is prepared according to the formula and process parameters in Table 1, and the waterproof membrane prepreg is prepared according to the following method.

[0072] The preparation method of the waterproof roll material prepreg comprises the following steps:

[0073] (1) Stir the base asphalt at a speed of 1100 rpm at 130°C for 30 minutes to obtain delightened asphalt;

[0074] (2) Stirring the delightened asphalt, softener, and hard asphalt at a speed of 1300 rpm at 150°C for 30 minutes to obtain the first mixture;

[0075] (3) The first mixture and the inorganic filler were stirred for 1 hour at 170° C. at a speed of 1300 rpm to obtain a waterproof membrane prepreg Y1.

Embodiment 2

[0077] This embodiment adopts the same flow process as embodiment 1 to carry out, and the difference is that in this embodiment:

[0078] The formulations and process parameters of the waterproof membrane prepreg compositions used are different, see Table 1 for details.

[0079] The waterproof membrane prepreg Y2 was prepared.

Embodiment 3

[0081] In this example, a waterproof membrane prepreg was prepared using a formula and method similar to that of Example 1, except that polyethylene wax I was replaced with polyethylene wax II by equal weight to prepare a waterproof membrane prepreg Y3. See Table 1 for details.

Abstract

The invention relates to the field of asphalt waterproof coiled material, and discloses a waterproof coiled material prepreg composition, a waterproof coiled material prepreg, a preparation method and application thereof. The composition contains two or more of the following components that are stored in combination or independently: compound asphalt, softener, inorganic filler, and the compound asphalt is base asphalt and hard asphalt with a content weight ratio of 1:0.10-0.35 A combination of asphalt; the softener is selected from at least one of polyethylene wax and polar amide wax. When the prepreg prepared by adopting the composition provided by the invention is applied to the waterproof coiled material, it can meet the oil-permeability requirement of the waterproof coiled material and has good adhesive performance.

Description

technical field [0001] The invention relates to the field of asphalt waterproof coiled material, in particular to a waterproof coiled material prepreg composition, a waterproof coiled material prepreg, a preparation method and application thereof. Background technique [0002] At present, there are few studies on prepregs for wet-laid waterproof membranes with tires. The new national standard "Wet-laid Waterproof Membranes" passed in 2017 has tightened the test methods for oil permeability of membrane products in terms of product technical requirements. Prevent manufacturers from adding inferior quality engine oil and light components. [0003] At present, most waterproof membrane prepregs usually add polypropylene (PP) to the base asphalt to meet the national standard's requirements for membrane oil permeability. [0004] However, when PP is added to the base asphalt, PP is easy to precipitate at low temperature, thereby reducing the bonding performance between the coating...
