1, polymer waterproofing membrane

There are three kinds of cold glue methods: high and low temperature adhesive white circle, volatile solvent-based polymer waterproof coiled material adhesive, curing two-component reactive type and hot melt type. The first two kinds volatilize at low temperature or the reaction speed is too slow, so the construction conditions above 5℃ and the requirements of-10℃ hot melt adhesive construction are completely acceptable. The polymer coil constructed by welding method can only be welded after the overlapping part of the coil is heated, or it can be constructed at the temperature of-10℃.

2. Self-adhesive coil

Self-adhesive coil has good low temperature performance, and can be operated at negative temperature after uncoiling, but the cohesion is weakened. For example, if it is laid on an airplane, the viscosity will increase and the temperature will rise, and the bonding method will be produced in the process of use. At high altitude and at the lap joint, it can be used for the low-temperature hot air heating method of thighs and building height, so it is also allowed to operate at the temperature above-10℃.

3. Polymer modified asphalt rolling material

There are two problems in low temperature construction of polymer modified asphalt winding materials. First, it is difficult to uncoil, except that the low temperature flexibility of elastomer modified asphalt winding materials can reach-18℃. Second, it is difficult to bond. In hot-melt construction, hot-melt adhesive is used to heat the bottom surface and base at the same time, so it can be operated at a low temperature above-10℃, but it consumes a lot of energy.

4, asphalt coil

Due to the limitation of uncoiling temperature, asphalt coiled material should be constructed at ambient temperature above 5℃.

Extended data:

Precautions for waterproofing membrane construction:

1, it is forbidden to carry out coiled material and heat preservation construction in rainy days.

2, coiled material waterproof layer leveling layer should meet the quality requirements, achieve the specified dryness.

3, in the corner of the roof, gutter, falling water, roof, coil, nodes, etc., should be carefully paved and closed, so as to be dense and firm, in line with the design requirements and the relevant provisions of the technical specifications for roof engineering. Corner, gutter, gutter, roof, etc. It should be covered with coils and additional layers.

4, coil laying, paste should avoid excessive stretching and folding. The exhaust between the base and the coil should be sufficient. After transverse exhaust, the rubber roller should be compacted.

5, coil lap width and laying should be straight, construction should be carried out in strict accordance with the elastic line at the grass-roots level.

6, laying insulation layer to protect the waterproof layer.
