To increase the rate of cure, current art of pencil leads improves this property by formulating high solids or fast drying polymer emulsions. However, due to the relatively slow drying characteristics of the aqueous adhesive itself, the cure time for the improved product to develop adequate initial tack still takes several hours. For example, CN107384253A discloses a pencil glue which is composed of the following components by mass percent: 75.7% of VAE emulsion, 5% of aqueous polyurethane emulsion, 10% of plasticizer, 0.2% of surfactant, 0.1% of preservative and 9% of distilled water.

The test steps are as follows:
and symmetrically clamping the sample on a clamp, wherein the distance from the clamping position to the nearest bonding section is 50mm +/-1 mm, and the acting force is ensured to be in the bonding surface.
The tensile testing machine is loaded at a constant speed, and the load change is maintained between 8.3MPa/min and 9.7 MPa/min.
