[0040]Rubber powder preparation example:

[0041]S1: Use a crusher to crush waste tires;

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

[0043]Preparation example of modified glass fiber cotton

[0044]The 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 and 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 proportions. Add water, glycolic acid, formic acid, acrylic resin and ethyl acrylate to the stirred tank and stir for 1.5h at room temperature. , The speed is 30r / min, and the acid modifier is obtained;

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

[0048]S3: Add the glass fiber cotton obtained by adding 30% of the weight of the acid modifier to the stirring tank for stirring the acid modifier. After adding the glass fiber cotton, use the stirring tank to treat the mixture of the acid modifier and the glass fiber cotton Stir, the speed is 30r / min, the stirring time is 1h, and the modified glass fiber cotton is obtained;

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

preparation example 2

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

[0052]S2: Use a crusher to crush large pieces of glass fiber cotton;

[0053]S3: Add the glass fiber cotton obtained by adding 30% of the weight of the acid modifier to the stirring tank for stirring the acid modifier. After adding the glass fiber cotton, use the stirring tank to treat the mixture of the acid modifier and the glass fiber cotton Stir, the stirring speed is 30r / min, and the stirring time is 1h;

[0054]S4: After the stirring, filter the acid modifier and glass fiber cotton; after filtering out the glass fiber cotton, spread the glass fiber cotton, and dry the glass fiber cotton to obtain the modified glass fiber cotton.

Abstract

The invention relates to the technical field of waterproof materials, and particularly discloses an asphalt waterproof coiled material and a preparation method thereof. The asphalt waterproof coiled material comprises two asphalt material layers, a tire cloth layer and two protective film layers, the two asphalt material layers are located on the two sides of the tire cloth layer respectively, thetwo protective film layers are located on the sides, away from the tire cloth layer, of the asphalt material layers respectively, the asphalt material layers are formed by paving an asphalt material,the tire cloth layer is formed by paving tire cloth, the protective film layers are formed by paving protective films. The asphalt material comprises the following components in parts by weight: 70 #asphalt, 10 # asphalt, pressure-reduced third-tier oil, rubber powder, an SBS modifier and talcum powder. The asphalt waterproof coiled material has the advantages of low temperature resistance and aging resistance.

Description

Technical field[0001]This application relates to the technical field of waterproof materials, and more specifically, it relates to an asphalt waterproof coiled material and a preparation method thereof.Background technique[0002]The current waterproof membrane is a rollable sheet-like waterproof material. Waterproof membranes are mainly used for building walls, roofs, tunnels, highways, subways, landfills, etc., and can play a role in resisting external rain and groundwater leakage. As a leak-free connection between the foundation of the project and the building, the waterproof membrane is the first barrier for the entire project’s waterproofing. It plays a vital role in the entire project. According to its main waterproof components, it can be divided into asphalt waterproof materials, Three types of bituminous waterproofing membranes: polymer modified waterproofing membranes and synthetic polymer waterproofing membranes. Asphalt waterproofing membrane is a rollable sheet-like water...
