Composite matrix based carrier modified asphalt self-adhesive waterproof coiled material

Abstract

The invention discloses a composite matrix based carrier modified asphalt self-adhesive waterproof coiled material, which is composed of three parts. Specifically, the first part is an HDPE film carrier, the second part is a high polymer modified asphalt self-adhesive glue film coating, and the third part is a low-alkaline glass fiber mesh cloth embedded and fixed in a high polymer modified asphalt self-adhesive material. The three parts are sticked and compounded together by the high polymer modified asphalt self-adhesive glue film coating to form the waterproof coiled material. The composite matrix based carrier modified asphalt self-adhesive waterproof coiled material disclosed in the invention can be made into an efficient waterproof material on the basis of maximumly reducing natural resource consumption, thus providing safety guarantee for engineering waterproofing.

Description

technical field [0001] The invention relates to a modified asphalt self-adhesive waterproof coiled material with a composite base carrier, which belongs to the field of building waterproof materials and civil engineering waterproofing Background technique [0002] With the ever-increasing scarcity of natural resources, material conservation in the field of civil engineering is gaining more and more attention. As a waterproof membrane that must be used in engineering waterproofing, it is of great significance to continuously improve the engineering performance of the product and reduce the consumption of natural resources. [0003] Yet traditional research in this area pays more attention to the improvement of waterproof material itself, such as CN1110301A, CN2358140Y, CN1105744C, CN2804216Y, CN2926229Y etc., although partly reveals in the above-mentioned scheme " the EPDM, asphalt linoleum or chlorinated polyethylene As the coil layer, the inorganic silicate thermal insulat...

[0003] Yet traditional research in this area pays more attention to the improvement of waterproof material itself, such as CN1110301A, CN2358140Y, CN1105744C, CN2804216Y, CN2926229Y etc., although partly reveals in the above-mentioned scheme " the EPDM, asphalt linoleum or chlorinated polyethylene As the coil layer, the inorganic silicate thermal insulation material is used as the thermal insulation layer, and the glass fiber mesh cloth is used as the reinforcement layer for a three-layer structure", but this structure has some inherently difficult problems: in long-term use , the middle layer will carry the EPDM on the top layer and separate from the glass fiber mesh, losing the proper waterproof and heat preservation effect, and the construction of this structure is laborious when laying, and the glass fiber is placed at the bottom of the heat preservation layer. With shear strain performance, it will crack after a long time of use

[0004] At present, water leakage in civil construction projects is a frequent disease. Water leakage not only seriously affects the effective use of building functions, but also can cause various building diseases, resulting in a reduction in the service life of buildings.

In modern buildings, there are a large number of buildings that have to be demolished in advance because of poor engineering waterproofing, which leads to high maintenance and maintenance costs during use.

[0005] In order to ensure the safety of building waterproofing, the current national building codes advocate the adoption of multi-fortification technical measures for new buildings. On the one hand, more fortifications cause the consumption of a large amount of waterproof materials and natural resources, and on the other hand, they also bring heavy purchases to users. cost burden
