Embodiment Construction

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0018] An embodiment of the present invention provides an HDPE reactive adhesive waterproof membrane, which comprises an isolation layer, a non-adhesive coating layer, a self-adhesive adhesive layer, and a carcass in sequence from top to bottom.

[0019] The isolation layer is a linear saturated polyester resin isolation film with wax on one side and no wax on the other side. The waxed side is bonded to the non-adhesive coating layer.

[0020] The non-adhesive coating layer is made of the following components according to the mass ...

Abstract

The invention relates to an HDPE reaction sticky waterproof coil material, which sequentially comprises a separation layer, a non-sticky coating film layer, a self-adhesive layer and a base body fromtop to bottom, wherein the separation layer is a linear saturated polyester resin separation film, the non-sticky coating film layer is made of the following components by mass: 80-95% of an acrylic emulsion, 4-20% of an alcohol organic solvent and 0.3-1% of an A reaction aid, the non-sticky coating film layer comprises a strong adhesion type hot melt pressure sensitive adhesive and a B reaction aid, the content of the B reaction aid is 0.3-1%, the base body is a HDPE homogeneous sheet layer, and the A reaction aid and the B reaction aid respectively are a silane coupling agent. According to the present invention, the HDPE reaction sticky waterproof coil material has much higher peeling strength compared to the ordinary HDPE self-adhesive waterproof coil material, is easy to construct, andcannot stick to the construction personnel.

Description

technical field [0001] The invention relates to a HDPE reactive adhesive waterproof coiled material, which belongs to the field of waterproof coiled materials. 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. Nowadays, after the isolation film is torn off, because the hot-melt pressure-sensitive adhesive of the adhesive layer is too strong, it is easy to bond the construction personnel, which causes a lot of inconvenience to the construction site. [0003] Therefore it is necessary to design a kind of HDPE reactive adhesive waterproof membrane to overcome the above problems. Contents of the invention [0004] The purpo...
