Embodiment 1

[0030] Elastic aid was made by:

[0031] Step A, 2,4-dichloro-6-methoxy-1,3,5-triazine and toluene were added three-necked flask equipped with a stirrer, stirred at room temperature to 2,4-dichloro-6- -1,3,5-triazine was completely dissolved, and then placed in an ice-water bath system, bis (o) phenyl disulfide, stir, and the mass fraction of 10% sodium carbonate solution to adjust the system between pH 5-6, the reaction system was heated to 46 ℃, and stirring was continued 7H reaction, the reaction was stopped until the reaction was cooled to room temperature, filtered, and the filter cake was washed with deionized taken three times with water, and dried in vacuo at 40 ℃ tank dried to constant weight to give an intermediate product;

[0032] Procedure B, the intermediate product obtained in Step A 1 and a half of N, N- dimethylformamide was added three-necked flask equipped with a stirrer, and stirred to complete dissolution of Intermediate 1, then [3- (trimethoxy silyl) propyl] ...

Embodiment 2

[0038] Elastic aid was made by: with reference to the steps in Example 1.

[0039] The amount of the material in each step such as shown in Table 2.

[0040] Table 2

[0041]

[0042]

Embodiment 3

[0044] One kind of water fracture waterproofing membrane, comprising the following component parts by weight: 50 parts bitumen, 5 parts of a plasticizer, an elastic aid prepared in Example 1 2.5 parts, 12 parts of a flame retardant, an ultraviolet absorber 1.5, 2.5 parts antioxidant, 0.5 parts of a softening agent, wherein the plasticizer is the DOP; 3 ratio of the flame retardant is an organic flame retardant and an inorganic flame retardant in accordance with the quality: 1 were mixed mixture; said UV absorption agent is UV-329; the antioxidant is antioxidant 1010 and 168 antioxidant at a mass ratio of 1: 2 were mixed mixture; the softening agent is an aromatic oil.

[0045] This kind of water-fracture-resistant waterproof membrane is made of the steps of:

[0046]Softener while mixing with the bitumen and heated to 55 ℃, stirred for 20min; a plasticizer, an elastic aids, flame retardants, ultraviolet absorbers and antioxidants, heated to 75 ℃, stirred for 30min, and was at 135 ...

Abstract

The invention discloses a water-resistant and fracture-resistant waterproof roll and a preparation method thereof, and belongs to the technical field of waterproof materials, and the water-resistant and fracture-resistant waterproof roll comprises the following components in parts by weight: 50-75 parts of asphalt, 5-16 parts of a plasticizer, 2.5-10.5 parts of an elastic aid, 12-18 parts of a flame retardant, 1.5-6.5 parts of an ultraviolet absorbent, 2.5-6.5 parts of an antioxidant and 0.5-3.5 parts of a coloring agent. 2, 4-dichloro-6-methoxy-1, 3, 5-triazine, di (o-amino) phenyl disulfide, [3-(trimethoxysilyl) propyl] succinic anhydride and hydroxyl-terminated polydimethylsiloxane are utilized to react step by step to produce the elastic auxiliary agent. The main chain of the elastic auxiliary agent is mainly composed of a flexible chain, hydrogen bonds are easily formed, an interpenetrating network is formed in a waterproof roll system, the toughness of the waterproof roll is improved, and the fracture resistance of the waterproof roll is improved.

Description

Technical field [0001] The present invention belongs to the technical field of waterproof material, in particular, it relates to a waterproofing membrane and a preparation method of water fracture resistance. Background technique [0002] Waterproofing membrane is mainly used for building walls, roof, and tunnels, highways, landfills, etc., to play against the rain outside a groundwater seepage can curl into a roll of flexible building materials, as a basis for engineering no leakage connection between the building, the whole project is the first barrier of water plays a vital role in the whole project. [0003] Depending on its main constituent material, into bitumen membrane, polymer modified bitumen and a synthetic polymer waterproofing membrane; no divided according to different carcass carcass web, the web membrane, glass batt web, a polyethylene web and the glass cloth fetal fetal membrane. Waterproofing require good water resistance, stability to changes in temperature (at...
