Embodiment 1

[0018] A root-blocking TPO waterproof coating, its components and mass ratio are: TPO: 40%; EPPE: 20%; root-blocking agent: 7%; active calcium: 10%; anti-aging agent: 3%; aromatic oil: 20%; plasticizer DOP: 3%.

Embodiment 2

[0019] Embodiment 2: a kind of preparation technology of root resistance TPO waterproof coating, the steps are as follows:

[0020] 1) According to the mass ratio, select the appropriate metering raw materials, the raw materials are as follows: TPO, EPPE, root inhibitor, active calcium, anti-aging agent, aromatic oil, plasticizer DOP.

[0021] 2) Add the above-mentioned raw materials into the batching mixing tank, and heat to an appropriate temperature for sufficient stirring.

[0022] 3) After the raw materials in the mixing tank come out, they enter the colloid mill for grinding to ensure that the raw materials are pure, hygienic and pollution-free.

[0023] 4), the raw materials from step 3) enter the cooling and stirring tank to make a root-resistant TPO waterproof coating.

[0024] 5), the waterproof coating that comes out in step 4) is inspected and tested, packed and stored in storage, and made into a root-blocking TPO waterproof coating that meets the standards.

Abstract

The invention discloses a root-resisting TPO (thermoplastic polyolefin) waterproof coating and a preparation process thereof. The root-resisting TPO waterproof coating comprises the following components in percentage by weight: 30-50 percent of TPO (thermoplastic polyolefin), 10-30 percent of EPPE (Easy Processing Polythene), 4-8 percent of root resisting agent, 5-15 percent of active calcium, 1-5 percent of anti-aging agent, 10-35 percent of aromatic hydrocarbon oil and 1-4 percent of plasticizer DOP (Dioctyl-Phthalate). The root-resisting TPO waterproof coating has the advantages of convenient construction, good aging resistance, high tensile strength, large elongation, no need of a protection layer during exposure, and low cracking rate of a coating layer after the coating is cured; and a good waterproof effect can be kept for a long time.

Description

technical field [0001] The invention belongs to the field of waterproof coatings, in particular to a root-blocking TPO waterproof coating. Background technique [0002] Waterproof materials are widely used in the field of building material protection. After coating the building with waterproof coating, the building can be isolated from the external environment, thereby preventing the intrusion of rainwater, groundwater and other corrosive liquids and moisture in the air into the building. corrosion caused by building materials and prolong the service life of building materials. [0003] Waterproof materials mainly include waterproof coatings and waterproof membranes. Among them, waterproof membranes mainly include asphalt waterproof membranes, modified asphalt waterproof membranes, polymer waterproof membranes, etc. The construction process of waterproof membranes is complicated, and the requirements for construction personnel are high, so the application range is narrow. ...
