Description
Technical Field
The invention relates to the field of waterproof rolls, in particular to a novel non-asphalt-based self-adhesive waterproof roll.
Background
The self-adhesive waterproof coiled material does not need to be heated during construction, particularly the self-adhesive coiled material constructed by a wet paving method does not need to be coated with a base layer treating agent on a base layer, is safe in construction and environment-friendly, and is a waterproof coiled material which is developed more quickly in recent years. The self-adhesive waterproof coiled materials applied to the market are mainly divided into asphalt-based self-adhesive waterproof coiled materials and non-asphalt-based self-adhesive waterproof coiled materials. The asphalt-based self-adhesive waterproof coiled material has poor cohesiveness under low temperature conditions; the general non-asphalt-based waterproof coiled material has poor weather resistance and water resistance, and also has the phenomenon that a polymer base material and a polymer self-adhesive are easy to separate, so that the stripping phenomenon is more obvious after the coiled material is subjected to thermal aging.
The peeling strength of the non-asphalt high-molecular waterproof coiled material is improved by adding polar resin into a high-molecular sheet, and specifically, the non-asphalt high-molecular waterproof coiled material is obtained by melting and extruding SIS pressure-sensitive hot melt adhesive on the high-molecular sheet based on raw materials such as low-density polyethylene, maleic anhydride graft modified polyethylene, light calcium carbonate subjected to surface treatment by a silane coupling agent, an ultraviolet absorbent, a main antioxidant, an auxiliary antioxidant, stearic acid, iron white powder and the like, and finally covering a protective layer. The proposal mainly improves the peel strength of the waterproof coiled material by improving the polar resin-maleic anhydride graft modified polyethylene, and has higher raw material and processing cost.

The filler is one or more of calcium carbonate, talcum powder, heavy calcium, light calcium and calcined kaolin.
In order to increase the thermal stability of the system, the auxiliary agent is quartz sand.
Furthermore, the pigment can adopt reddish brown powdered iron oxide red to play a role in dyeing materials.
The preparation method of the non-asphalt-based self-adhesive layer comprises the following specific steps:
s1: heating the tackifying resin according to the weight ratio until the tackifying resin is completely dissolved, adding styrene butadiene rubber, continuously heating to 178-182 ℃, and then stirring and modifying for 2-3 hours at the temperature;
