PVC self-adhesive floorboard with water-resistant glue
A self-adhesive floorboard with water-resistant glue comprises from a top to a bottom sequentially a main body layer, an isolation layer and the water-resistant glue, wherein each component proportion of component composition of the water-resistant glue based on a weight percentage is: 34-38% for a styrene-isoprene-styrene block copolymer, 46.4-50.4% for C5 hydrogenated petroleum resin, 13-17% for cycloalkyl rubber extender oil and 0.5-0.6% for a hindered phenol antioxidant. The isolation layer between the main body layer and the water-resistant glue is a PVC film of OPHR. The water-resistant glue of the PVC self-adhesive floorboard with the water-resistant glue is provided with a water-resistance function, and can prevent a plasticizer from drifting away from the PVC floorboard to affect stickiness of the water-resistant glue.
1. A PVC self-adhesive floorboard with water-resistant glue, comprising a main body layer, an isolation layer and water-resistant glue from a top to a bottom; wherein the water-resistant glue comprises: styrene-isoprene-styrene block copolymer from 34 to 38 weight percent, C5 hydrogenated petroleum resin from 46.4 to 50.4 weight percent, cycloalkyl rubber extender oil from 13 to 17 weight percent, and hindered phenol antioxidant from 0.5 to 0.6 weight percent; wherein the main body layer comprises a PU coating, a wear-resistance layer, a printing layer, a first PVC layer and a second PVC layer.
