Problems solved by technology

[0003] However, the special adhesives for waterproofing membranes currently on the market are used in relatively low temperatures during construction in winter, especially in northern regions where the temperature is often around -20°C, and the lap joints are easy to warp, so it is necessary to develop a new waterproofing The special glue for coils makes the coils still have a good lap joint effect in ultra-low temperature environment, ensuring that the lap joints will not be warped

preparation example Construction

[0054] The second aspect of the present invention provides a method for preparing a special glue for waterproof coiled materials in an ultra-low temperature environment, the steps include:

[0055] (1) drop described naphthenic oil, antioxidant into stainless steel reactor;

[0056] (2) After the temperature rises to 140°C, add SBR rubber, and control the temperature of the reactor at 150°C;

[0057] (3) After the SBR rubber is completely dissolved, put in hydrogenated C5 petroleum resin, aromatic modified terpene resin, ethylene-acrylic acid salt, and carboxyl-terminated hyperbranched polyester, and control the temperature of the stainless steel reactor within 200°C and stir for 30-60 minutes , evacuate to -0.085MPa, discharge and pack for cooling.

Abstract

The invention relates to the technical field of polymer adhesives, in particular to an adhesive special for waterproof rolls in an ultralow temperature environment and a preparation method of the adhesive. The adhesive special for the waterproof rolls in the ultralow temperature environment comprises hydrogenated C5 petroleum resin. The prepared adhesive special for the waterproof rolls in the ultralow temperature environment can have excellent initial adhesivity and persistent adhesivity while keeping excellent coating performance, and has a good lap joint effect even in the ultralow temperature environment to prevent warping of joint edges.

Description

technical field [0001] The invention belongs to the technical field of polymer adhesives, and more specifically, the invention relates to a special adhesive for waterproof membranes in an ultra-low temperature environment and a preparation method thereof. Background technique [0002] The polymer self-adhesive waterproof membrane generally reserves a 70mm wide self-adhesive lap edge during the coating process to ensure that the lap material has sufficient adhesive strength when the base surface cannot be fully paved to ensure The lapped edges will not warp to achieve effective bonding. [0003] However, the special adhesives for waterproofing membranes currently on the market are used in relatively low temperatures during construction in winter, especially in northern regions where the temperature is often around -20°C, and the lap joints are easy to warp. Therefore, it is necessary to develop a new waterproofing The special glue for coils makes the coils still have a good ...
