Problems solved by technology

However, in the specific construction, after the isolation film is torn off, because the hot-melt pressure-sensitive adhesive of the adhesive layer has too strong adhesion, it is easy to bond the construction personnel, which causes a lot of inconvenience to the on-site construction.

Abstract

The invention provides an HDPE chemical bonding type self-adhesive waterproof coiled material. According to the invention, through arrangement of a self-adhesive adhesive layer and a matrix, the adhesive layer can be firmly adhered to a concrete layer and has high peel strength; through arrangement of an isolation layer and a non-adhesive coating layer, easy construction and no adhesion to construction personnels are realized; through addition of a diblock SDS thermalplastic elastomer and an SIS thermoplastic elastomer, a hot-melt pressure-sensitive adhesive has meltability and thermoplasticity of plastic and elasticity and toughness of rubber; through limitation of shore hardness of the SIS thermoplastic elastomer, the hot-melt pressure-sensitive adhesive has meltability and thermoplasticity of the plastic and elasticity and toughness of the rubber; through limitation of the type of a compatibilizer, a product has widened construction temperature range; through limitation of carbon-5petroleum resin, the waterproof coiled material has good construction temperature, and the hot-melt pressure-sensitive adhesive has better adhesiveness; and through limitation of the type of a tackifier, the hot-melt pressure-sensitive adhesive can maintain good peel strength at a normal temperature.

Description

technical field [0001] The invention relates to a waterproof coiled material, in particular to a HDPE chemically bonded self-adhesive waterproof coiled material. Background technique [0002] Since the 21st century, pre-paved anti-adhesive construction technology has been mostly used in the construction of waterproof membrane paving in subway tunnels. During pre-paving anti-adhesive construction, it is necessary to tear off the surface isolation film, and then pour the freshly mixed liquid post-cast concrete on it, and wait for the post-cast concrete to solidify. However, in the specific construction, after the isolation film is torn off, because the hot-melt pressure-sensitive adhesive of the adhesive layer has too strong adhesion, it is easy to bond the construction personnel, which causes a lot of inconvenience to the on-site construction. Contents of the invention [0003] In view of this, the present invention proposes a HDPE chemically bonded self-adhesive waterproo...
