Waterproof coiled material with heat insulation and reflection functions

Abstract

The invention discloses a waterproof coiled material with heat insulation and reflection functions, which is prepared from the following components in percentage by mass: 10-25% of polypropylene, 20-35% of polyethylene, 20-50% of TPU thermoplastic polyurethane), 0.5-15% of metal oxide, 3-25% of reflection and emission modifying material, 0.1-5% of antioxidant and 0.1-5% of light stabilizer. The metal oxide adopts the special-structure Ca(OH)2; and the reflection and emission modifying material adopts one or more of ferric oxide, manganese peroxide, cobaltic oxide, copper oxide and other reflective spinel materials. The waterproof coiled material with heat insulation and reflection functions is composed of a thermoplastic polyolefin material, a filler with reflection and emission functions and a high-performance self-adhesive coating, and has excellent functions of water resistance, weather resistance, heat insulation and reflection.

Description

technical field [0001] The invention relates to new building energy-saving materials, in particular to a new type of waterproof coiled material. Background technique [0002] With the rapid development of my country's construction industry and the increasingly prominent energy crisis, the energy saving and consumption reduction of buildings is becoming more and more important. my country's building energy consumption accounts for about 27% of the country's total energy consumption, ranking first in all types of energy consumption in the country. The energy consumption of heating and air conditioning accounts for 55% of the total energy consumption of buildings, and it is still increasing at a rate of 1% per year. Therefore, the research and development of building thermal insulation coatings has significant economic, environmental and social benefits. [0003] The traditional waterproof membrane should be cut according to the shape of the waterproof base during waterproof ...

AI Technical Summary

Problems solved by technology

[0004] 1. Directly affect the appearance of the waterproof layer;

[0005] 2. Due to the durability of high-grade waterproof membranes for decades, there are few domestic adhesives that can match them. In this way, when the adhesive loses its bonding function in advance, it will Cause waterproofing failure of waterproof membrane;

[0006] 3. It is difficult to protect and maintain the waterproof membrane after construction: due to the bonding between the waterproof membrane and the base layer, whether it is full paving, point paving, strip paving, or empty paving, there will be a water-tight layer between the coiled material and the base layer. Regardless of any part of the penetrating damage, degumming, glue leakage, even if there is only one place, the waterproof function of the entire connected layer will be completely lost. If the damage and defect cannot be found, local repairs will be impossible. Only redo the waterproof layer
