Spontaneous heating self-adhesive waterproof coiled material

Abstract

The invention belongs to the technical field of waterproof coiled materials, and discloses a spontaneous heating self-adhesive waterproof coiled material. The spontaneous heating self-adhesive waterproof coiled material comprises a non-woven fabric breathable layer, a spontaneous heating layer, an isolating membrane and a coiled material waterproof layer, wherein the non-woven fabric breathable layer comprises an outer bag capable of isolating air and a microporous breathable membrane, and the outer bag is attached to the surface of the microporous breathable membrane in a peelable mode; the spontaneous heating layer is attached to the microporous breathable membrane, so that the microporous breathable membrane is located between the outer bag and the spontaneous heating layer; the spontaneous heating layer is internally subjected to an oxidation reaction and contains iron powder, a carbon compound, silicic acid mineral particles and a catalyst; the isolating membrane is attached to the side, away from the non-woven fabric breathable layer, of the spontaneous heating layer; and the coiled material waterproof layer is arranged between the isolating membrane and the spontaneous heating layer. According to the spontaneous heating self-adhesive waterproof coiled material, an additional heating device is not needed, the outer bag is torn so that spontaneous heating of the waterproofcoiled material can be achieved, heating is very uniform, the good adhesive performance can be kept in a low-temperature environment, and the adhesive effect between the coiled material and a base surface and the overlapping effect between the coiled materials are improved.

Description

technical field [0001] The invention belongs to the technical field of waterproof coiled material, and relates to a self-heating self-adhesive waterproof coiled material. Background technique [0002] At present, the adhesive material of self-adhesive waterproof membrane is mainly bitumen-based material. Due to its material characteristics, its adhesive performance will be greatly reduced in winter low temperature environment, which will affect the adhesion effect between the membrane and the base surface and the relationship between the membrane and the membrane. The overlapping effect will reduce the reliability of the waterproofing project; when constructing self-adhesive waterproofing membranes in low temperature environments, a common measure is to use a hot air blower to heat the membrane and the base surface to improve the adhesion effect of the membranes, but this method In actual operation, there are defects such as short heating time, uneven heating, cumbersome con...
