Problems solved by technology

However, when the base is uneven, there is floating dust on the surface, the base is wet or the temperature is low, the self-adhesive waterproof membrane will not be firmly bonded to the base, and it is easy to form a hollowing phenomenon, and a film will be formed on the interface of the base. It cannot be perfectly bonded to the base layer, that is, after the construction, the coiled material is peeled off from the base layer, and the interface is separated, and the modified asphalt material cannot be left on the base layer, which will affect the waterproof effect

Abstract

The invention discloses a high initial adhesion self-adhering waterproof roll which is characterized by comprising the following components in percentage by mass: 35-55% of petroleum asphalt, 5-25% of a softening agent, 5-25% of a modifier, 2-8% of an adhesive, 0.1-2% of a surfactant, 0.1-3% of an anti-aging agent and 5-20% of a filling agent.

Description

technical field [0001] The invention relates to a self-adhesive waterproof coiled material with high initial viscosity and a preparation method. Background technique [0002] With the development of the economy and the progress of the times, the requirements for building materials are getting higher and higher. Polymer waterproof membranes are recognized as waterproof materials with excellent performance and are widely used in waterproof and moisture-proof in industrial and civil construction fields. There are many disadvantages in the construction of self-adhesive waterproof membranes, which are as follows: (1) cumbersome welding construction; (2) poor anti-leakage effect, serious water leakage; (3) poor resistance to damage, prone to puncture or The tearing phenomenon requires manpower and material resources to repair, which shortens the service life of the waterproof membrane and causes a waste of resources and funds. In addition, the general polymer self-adhesive waterp...
