Big Size Self Adhesive Bitumen Waterproof Roll Product Self-adhesive

1 self-adhesive asphalt waterproofing membrane rubber self-adhesive asphalt waterproofing membrane production process is relatively simple, through the fine material can be achieved by the product self-adhesive needs, at present, the domestic production of self-adhesive coil manufacturers a lot, Cold-rolled plate self-adhesive process, a domestic roller barrels of self-adhesive coolingequipment, the basic product requirements can be achieved. Self-adhesive rubber asphalt waterproofing membrane, with pressure sensitivity, peelability and adhesion characteristics, the coil is mainly two types; one is modified asphalt waterproofing membrane for the substrate + pressure sensitive self-adhesive Glue + isolation paper or silicon insulation film composition; one is made of PVC as the substrate + pressure sensitive self-adhesive + isolation paper or silicon insulation film composition. Regardless of the kind of substrate, the requirements should be better heat resistance, low temperature flexibility, a greater tensile strength and elongation at break.

Pressure-sensitive adhesive pressure-sensitive adhesive, at room temperature, a little pressure can make the contact surface to produce the maximum adhesion of the non-drying adhesive. Its role is to modify the asphalt waterproofing membrane with pressure sensitivity and adhesion characteristics. Adhesion has four elements to decide.

Adhesion T; refers to the self-adhesive coil and the sticky material with the lightest pressure, the fastest contact speed immediately after the separation, the interface peel off the force. Adhesive force A refers to the force that is peeled off between the self-adhesive web and the adherend after proper posting. Cohesion C refers to the cohesion of the adhesive layer after the adhesive sheet is adhered. Sticky force K; refers to the force between the pressure sensitive adhesive and the web material. When the four forces to meet the T
