Problems solved by technology

[0004] The quality and service life of building waterproof materials will directly affect the quality of construction projects. Traditional asphalt waterproof materials have shortcomings such as high-temperature flow and low-temperature brittleness, and the construction process is relatively cumbersome, so they are gradually being eliminated.

Embodiment 1

[0020] A TPO waterproof membrane, calculated in parts by weight, including: 50 parts of thermoplastic polyolefin (POE), 25 parts of low-density polyethylene (LDPE), 25 parts of light carbonic acid treated with silane coupling agent Calcium, 0.2 part of UV-9 ultraviolet absorber, 0.1 part of 1010 primary antioxidant, 0.2 part of 168 secondary antioxidant, 0.3 part of stearic acid and 3.0 part of titanium dioxide.

[0021] The steps of a production process of a TPO waterproof coiled material are as follows:

[0022] a. Kneading: 25 parts of low-density polyethylene (LDPE), 25 parts of light calcium carbonate treated with silane coupling agent, 0.2 part of UV-9 ultraviolet absorber, 0.1 part of 1010 primary antioxidant, 0.2 Add 168 parts of auxiliary antioxidant into the high-speed kneader for kneading. Before adding, ensure that the temperature in the kneader is kept at 90±5°C, and the kneading time is 5 minutes. The above materials are evenly dispersed;

[0023] Add 0.2~0.5 p...

Embodiment 2

[0028] A kind of TPO waterproof roll material, compare with embodiment 1, under the situation that other conditions are completely identical with embodiment 1, only change the number of parts of low-density polyethylene (LDPE), take 30 parts of low-density polyethylene in embodiment 2 , the parts by weight of other components do not change, and are produced according to the production process of the TPO waterproof membrane described in Example 1 to prepare the TPO waterproof membrane.

Embodiment 3

[0030] A kind of TPO waterproof roll material, compare with embodiment 1, under the situation that other conditions are completely identical with embodiment 1, only change the number of parts of low-density polyethylene (LDPE), take 35 parts of low-density polyethylene in embodiment 3 , the parts by weight of other components do not change, and are produced according to the production process of the TPO waterproof membrane described in Example 1 to prepare the TPO waterproof membrane.

[0031] The performance of the TPO waterproof membrane prepared according to the above three examples is tested. The data obtained from the test shows that the content of low-density polyethylene (LDPE) plays a key role in the performance of the TPO waterproof membrane. The test results are shown in Table 1:

[0032] Table 1:

[0033]

[0034] It can be seen from Table 1 that the content of low-density polyethylene (LDPE) has the following effects on the prepared TPO waterproof membrane: ten...

Abstract

The invention provides a TPO waterproof coiled material comprising, by weight: 40-60 parts of POE, 15-35 parts of LDPE, 25-27 parts of lightweight calcium carbonate, 0.1-1.5 parts of an ultraviolet absorber, 0.1-0.5 parts of a main antioxidant, 0.2-0.8 parts of an auxiliary antioxidant 0.2-0.5 parts of stearic acid and 2.0-5.0 parts of titanium dioxide. With the process, the produced waterproof coiled material has the advantages of high strength, aging resistance, puncture resistance, high elongation, high deformation resistance, reliable fixing, good waterproof performance, moderate softness, high welding performance, and high welding strength. With the material, construction is convenient.

Description

technical field [0001] The invention relates to the field of waterproof rolls, in particular to a TPO waterproof roll and a production process thereof. Background technique [0002] As we all know, with the rapid development of urbanization, all kinds of buildings have more and more requirements for waterproof membranes, and the quality requirements for waterproof membranes are also getting higher and higher. my country's Building Waterproof Association has also repeatedly advocated that various waterproof membranes Material manufacturers must constantly develop new products to be used in modern building waterproof materials, and at the same time have strict control over the quality of waterproof membranes. [0003] TPO machine thermoplastic polyolefin, through advanced polymerization technology, polymerize ethylene-propylene rubber and polypropylene to synthesize resin. The synthesized resin not only has the low-temperature flexibility and weather resistance of ethylene-prop...
