A reflective fire-retardant insulation and waterproofing method for preparing recyclable

The present invention relates to reflective insulation and waterproofing retardant preparation recovered in weight percentage basis, the waterproofing material formulation is as follows: Ethylene propylene copolymer elastomer 55 - 30% %; polyolefin block copolymers of 2% to 30%; 2% to 5% titanium dioxide; cenospheres 1% to 8%; 0.01% to 0.05% of carbon black; halogen-free phosphorous flame retardant 10% to 25 %; 3% to 5% of antimony trioxide; UV agent, from 0.01% to 0.5%; 0.1% to 0.25% of antioxidant; 0.1% to 0.6% of the light stabilizer, the weight percentage of the total feed is 100 %. The preparation method of the present invention is simple and efficient, good waterproofing prepared overall performance, particularly excellent flame retardancy reflective insulation, weather up to 20 years, and reaches the useful life can be recycled, to achieve green energy saving.
