Low temperature and wetness bondable macromolecular self-adhesive waterproof coil material

Abstract

The invention relates to a low temperature and wetness bondable macromolecular self-adhesive waterproof coil material, which comprises a base layer. The upper surface and lower surface of the base layer are provided with a self-adhesive layer, and the outer surface of the self-adhesive layer is provided with a covering layer. The coil material provided by the invention has the advantages of reasonable structure, good adhesion at low temperature, nondecreasing adhesion when encountering water, great tensile strength and large elongation, and is especially suitable for waterproof construction in cold areas and in winter. The self-adhesive coil material construction is cold operation, has no need for naked flame, does not produce pollution, and does not cause energy waste, and is especially suitable for waterproof engineering at granaries, oil depots, chemical plants and the like not easy for naked flame operation. The coil material is convenient to maintain, can save a lot of maintenance cost, and has high tensile strength, good dimensional stability, and lasting and stable waterproof effect.

Description

【Technical field】 [0001] The invention relates to a waterproof coiled material, in particular to a polymer self-adhesive waterproof coiled material which can be bonded at low temperature and with water, and belongs to the technical field of waterproof materials. 【Background technique】 [0002] With the development of the construction industry, my country's waterproof materials have developed rapidly. In recent years, on the basis of satisfying the product's use function, more and more supports the development of new waterproof materials that are environmentally friendly and energy-saving, and limit the use of heat that has a greater impact on the environment. Melting coils and self-adhesive coils that can be cold-applied have been vigorously promoted and applied all over the world. [0003] Self-adhesive roll material has a series of characteristics such as good low temperature flexibility, high elongation, adaptability to base deformation, crack resistance, good self-healing...

AI Technical Summary

Problems solved by technology

However, the existing self-adhesive waterproof materials have many unsatisfactory places, the most significant shortcoming of which is the problem of not bonding at low temperatures. The construction of ordinary self-adhesive waterproof membranes generally requires the temperature to be above 10°C. Low, the adhesive force of the coil is reduced, and usually needs to be applied by heating, and the characteristics of the col
