Problems solved by technology

[0009] (1) The preparation of this kind of self-adhesive requires a high temperature of 180 ° C to 200 ° C, which can cause some plasticizers to overheat and oxidize; when the asphalt is 190 ° C to 200 ° C, a large amount of asphalt fume will pollute the environment, and the cost of asphalt fume treatment is high. , long preparation time and high energy consumption
[0010] (2) Since thermoplastic elastomers are difficult to dissolve in asphalt, they need to be ground by a colloid mill to achieve the purpose of blending. Generally, they need to be stirred and ground for about 3.5 hours, and the energy consumption is too large
[0011] (3) The molding temperature is high, the carcass shrinks greatly (about 1%), the process is complicated, and the energy consumption is high
[0012] (4) When polymer materials are used as the main material layer, this process cannot be used for manufacturing

specific Embodiment 2

[0092] Specific embodiment 2: as shown in Figure 2, a kind of macromolecule self-adhesive waterproof roll material, it adopts the self-adhesive of specific embodiment 1 to make, is made of main material layer 1, two layers of self-adhesive that are made of self-adhesive The adhesive layer 3 and two isolation layers 4 are formed. Two layers of self-adhesive layers are respectively compounded on the upper and lower surfaces of the main material layer, and two layers of isolation layers are respectively compounded on the outer surfaces of the two self-adhesive layers; the main material layer is composed of a synthetic resin sheet with a reinforcing material layer or a The fiber reinforced material layer consists of synthetic rubber sheets. Both outer surfaces of the body material layer have layers of fiber reinforcement material 2 .

[0093] like Figure 4 As shown, the main body material layer can also be made of a synthetic resin sheet or a synthetic rubber sheet, and the sur...

Abstract

The self adhesive consists of cross-linked asphalt, SBS rubber and tackifier, as well as SIS rubber, maleic anhydride, aluminum trichloride, thiram, magnesium chloride and calcium silicate. The self adhesive is cpddd with chemically modified cross-linked asphalt as main material at 150-170 deg.c, and has less pollution and low power consumption. It may be adhered to plasma modified polymer material and wet concrete. The present invention also discloses one kind of self adhering waterproof polymer coil made with the self adhesive and its production process, and the self adhering waterproof polymer coil has high adhesion strength between the adhesive and the main material layer.

Description

technical field [0001] The present invention relates to a self-adhesive, and also relates to a polymer self-adhesive waterproof roll made of the self-adhesive, and a manufacturing process thereof. Background technique [0002] Synthetic polymer waterproof membranes (including synthetic resin sheets and synthetic rubber membranes) have good physical properties, but because their surfaces are not easily bonded, they cannot achieve the ideal application effect. Therefore, the market share of such waterproofing membranes has been very small. Some people try to cold-coat a layer of double-sided self-adhesive membrane on the surface of the polymer membrane, but it is easily peeled off; The surface of the surface is difficult to bond, and the test did not take measures to treat the surface of the polymer coil. In addition, the self-adhesive does not match, so the effect is almost the same as the former. It can be seen that the technology of attempting to coat one deck of self-adh...
