[0041] S1: Use a shredder to shred waste tires;

[0042] S2: Sieve the crushed waste tires to obtain 60-70 mesh rubber powder.

[0043] Preparation example of modified glass fiber cotton

[0044] Glycolic acid, formic acid and ethyl acrylate in the following preparation examples were all purchased from Shanghai Yuna Chemical Co., Ltd., and the acrylic resin was a water-soluble acrylic resin purchased from Foshan Byton New Material Co., Ltd.

preparation example 1

[0046] S1: Weigh 80Kg of water, 2Kg of glycolic acid, 1Kg of formic acid, 12Kg of acrylic resin and 10Kg of ethyl acrylate according to the proportion, add water, glycolic acid, formic acid, acrylic resin and ethyl acrylate into the stirring tank, and stir at room temperature for 1.5h , rotating speed is 30r / min, obtains acid modifier;

[0047] S2: Use a pulverizer to pulverize the glass fiber cotton block to obtain glass fiber cotton;

[0048] S3: Add the glass fiber cotton obtained by adding S2 whose weight is 30% of the acid modifier weight into the stirring tank stirring the acid modifier. After adding the glass fiber cotton, use the stirring tank to mix the acid modifier and glass fiber cotton Stirring, the rotating speed is 30r / min, and the stirring time is 1h to obtain modified glass fiber cotton;

[0049] S4: After stirring, filter the acid modifier and glass fiber wool; after filtering out the glass fiber wool, spread the glass fiber wool, and dry the glass fiber wool ...

preparation example 2

[0051] S1: Weigh water, glycolic acid and formic acid according to the proportion, add water, glycolic acid and formic acid into the stirring tank, stir at a stirring speed of 30r / min, and stir at room temperature for 1.5h to obtain an acidic modifier;

[0052] S2: Use a pulverizer to pulverize the bulk glass fiber cotton;

[0053] S3: Add the glass fiber cotton obtained by adding S2 whose weight is 30% of the acid modifier weight into the stirring tank stirring the acid modifier.

Abstract

The application relates to the technical field of waterproof materials, and specifically discloses an asphalt waterproof coiled material and a preparation method thereof. The asphalt waterproofing membrane consists of two layers of asphalt material, one layer of tire cloth and two layers of protective film. One side of the layer, the asphalt material layer is paved with asphalt material, the tire cloth layer is paved with tire cloth, and the protective film layer is paved with protective film; the asphalt material contains the following parts by weight Components: No. 70 bitumen, No. 10 bitumen, minus third line oil, rubber powder, SBS modifier, talcum powder. The asphalt waterproof membrane has the advantages of low temperature resistance and aging resistance.

Description

technical field [0001] The application relates to the technical field of waterproof materials, more specifically, it relates to an asphalt waterproof coiled material and a preparation method thereof. Background technique [0002] At present, the waterproof membrane is a rollable sheet waterproof material. Waterproof membranes are mainly used in building walls, roofs, tunnels, highways, subways, landfills, etc., and can resist external rainwater and groundwater leakage. As a non-leakage connection between the engineering foundation and the building, the waterproof membrane is the first barrier for the waterproofing of the entire project and plays a vital role in the entire project. According to its main waterproofing materials, it can be divided into asphalt waterproofing materials, There are three types of asphalt waterproofing membranes: polymer modified waterproofing membrane and synthetic polymer waterproofing membrane. Asphalt waterproofing membrane is a rollable sheet...
