Embodiment 1

[0039] This example provides a recyclable reflective heat-insulating flame-retardant polymer waterproof membrane. The raw material formula of the polymer waterproof membrane is as follows: propylene ethylene copolymer elastomer TPO (VERSIFY2300 type) 55%; Polyolefin block copolymer OBC (INFUSE9000 type) 7%; titanium dioxide 4.69%; glass microspheres 7.5%; carbon black 0.01%; 2-carboxyethylphenylphosphinate flame retardant 20%; Antimony 5%; anti-ultraviolet agent UV-5310.1%; antioxidant B2250.2%; light stabilizer HALS20200.5%.

[0040] The coils are prepared as follows:

[0041]The specific steps are to first add propylene ethylene copolymerized elastomer and polyolefin block copolymer pellets from the first feeding port of a twin-screw extruder with a screw length-to-diameter ratio of 40 for mixing, and the screw speed is 25 rpm , the temperature is 170 ° C, after the polymer pellets are plasticized, they are transported to the second mixing section of the screw, and titanium...

Embodiment 2

[0044] This example provides a recyclable reflective, heat-insulating and flame-retardant polymer waterproof membrane. In terms of weight percentage, the raw material formula of the membrane is as follows: propylene ethylene copolymer elastomer TPO (VERSIFY2300 type) 50%; polyolefin block Copolymer OBC (INFUSE9000 type) 12%; titanium dioxide 4%; ceramic beads 5.3%; carbon black 0.03%; 2-carboxyethylphenylphosphinate pentaerythritol flame retardant 25%; antimony trioxide 3% ; Anti-ultraviolet agent UV-5310.07%; Antioxidant B2250.2%; Light stabilizer HALS20200.4%.

[0045] The preparation method of the coil is the same as in Example 1.

[0046] The coiled material in this example has been tested and meets the fire protection design requirements of the national standard GB50016-2012 "Code for Fire Protection Design of Buildings" regarding the fire protection design of factories, warehouses, and civil first-class fire-resistant buildings. At the same time, the tensile strength of...

Embodiment 3

[0048] This example provides a recyclable reflective, heat-insulating and flame-retardant polymer waterproof membrane. The raw material formula of the membrane is as follows: propylene ethylene copolymer elastomer TPO (VERSIFY2300 type) 45%; polyolefin block Copolymer OBC (INFUSE9000 type) 25%; titanium dioxide 4%; ceramic microbeads 4.5%; carbon black 0.03%; halogen-free phosphorus flame retardant 15.5%; antimony trioxide 5%; ; Antioxidant B2250.2%; Light stabilizer HALS20200.45%. Among the above, the halogen-free phosphorus-based flame retardant is a mixture of 2-carboxyethylphenylphosphinate and pentaerythritol 2-carboxyethylphenylphosphinate in a mass ratio of 3:2.

[0049] The preparation method of the coil is the same as in Example 1.

[0050] The coiled material in this example has been tested and meets the fire protection design requirements of the national standard GB50016-2012 "Code for Fire Protection Design of Buildings" regarding the fire protection design of fac...

Abstract

The invention relates to a recyclable reflective insulation flame-retardant high-molecular waterproof coiled material and a preparation method thereof. The high-molecular waterproof coiled material comprises the following raw materials in percentage by weight: 30-55% of propylene-ethylene copolymer elastomer, 2-30% of polyolefin block copolymer, 2-5% of titanium dioxide, 1-8% of hollow microspheres, 0.01-0.05% of carbon black, 10-25% of halogen-free phosphorus based flame retardant, 3-5% of antimony trioxide, 0.01-0.5% of anti-ultraviolet agent, 0.1-0.25% of antioxidant and 0.1-0.6% of light stabilizer; the total content of all raw materials is 100% by weight. The preparation method provided by the invention is simple and efficient; the prepared waterproof coiled water has good comprehensive performance, particularly the reflective insulation flame retardance is excellent, and the weather resistance lasts for 20 years; moreover, after the service life is over, the high-molecular waterproof coiled material can be recycled to realize green, energy-saving and environment-friendly effects.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a recyclable reflective, heat-insulating, flame-retardant polymer waterproof coiled material and a preparation method thereof. Background technique [0002] Recently, due to changes in building design and the use of new building components, higher and higher requirements have been placed on roof waterproofing membranes. In September 2009, the Ministry of Public Security issued Document No. 46 requiring that the exterior facades, including the roof, meet the fire rating of B1. Document No. 65 of March 2011 required even stricter requirements, and the fire rating was adjusted to Class A. At the same time, the "Twelfth Five-Year Plan" Comprehensive Work Plan for Energy Conservation and Emission Reduction issued by the State Council in August 2011 requires reducing energy waste and reducing exhaust emissions, and regards building energy conservation as an impor...
