Benefits of technology

The technical effect of this new type of water-resistant tape used for building materials is that it can withstand high temperatures without losing its ability to resist fire or damage caused during use. This makes them ideal for applications where safety concerns are important such as buildings underground.

Problems solved by technology

Technological Problem: Current Thin Film Waterproof Panel(TFFP) uses expensive chemicals like EPMN or other harmful substances for its purpose due to their potential negative impact on human health caused by these compounds. There have been efforts made towards developing new types of Green Flames Retarding Materials called Plasma Spray Paired Layer Repair Coating (SPRCoat). These coatings use less dangerous ingredients than current methods while still maintaining superior durability against environmental factors like UV light exposures.

Embodiment Construction

[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] A TPO waterproof membrane, calculated by mass specific gravity, including TPO: 8 parts, EVA: 2 parts, combined flame retardant: 2 parts, among which: TPO is made of American Santopping 101-55, and EVA is made of American DuPont 750 , the joint flame retardant is Al(OH) 3 and Mg(OH) 2 .

[0023] Al(OH) in the joint flame retardant 3 and Mg(OH) 2 Mix according to mass ratio 1:1.

[0024] A kind of preparation method of TPO waterproof coiled material: comprise the following steps:

[0025] Step A. Feeding: Add the selected raw materials TPO, EVA and joint flame retardant at a time according to the mass ratio of 4:1:1. The amount of each feeding is kept constant to ensure uniform injection plasticization and reduce injection molding. pressur

Abstract

The invention discloses a TPO (thermoplastic polyolefin) waterproof roll material and a preparation method thereof. The TPO waterproof roll material comprises, by weight, 8 parts of TPO, 2 parts of EVA (ethylene vinyl-acetate copolymer) and 2 parts of combined flame retardant, wherein the TPO is santoprene 101-55, the EVA is delrin 750, and the combined flame retardant is Al (OH)3 and Mg (OH)2. The waterproof roll material is reasonable in proportion, the TPO waterproof roll material prepared by the method has fine flame resistance and low-temperature bending resistance, the softness of a finished product prepared by the method is improved, and construction is facilitated.
