At present, vehicles such as motorcycles and motorcycles are indispensable for people in life, that is, they are convenient to travel, and they can exercise and enjoy the scenery along the way. Therefore, riding helmets are also one of the standing tools, which can greatly reduce the damage caused by falling or collisions in the process of riding electric bicycles or motorcycles. The cap of riding helmets has a foam inner layer that can absorb Buffer the impact of accidents and reduce injuries. Different types of adhesives used in the bonding of helmet shells have problems such as development time, strength, high and low temperature resistance, odor, and factory inspection and environmental protection. As a result, the safety of helmet riding users is not stable and effective in all aspects. Protection.

Outer ABS: high strength, high temperature resistance, corrosion resistance

Middle EPS: high-density material, effectively buffering external forces

Inner cushioning material: sweat-absorbent and quick-drying, comfortable and breathable

Hot melt glue machine function: the outer layer of ABS + middle layer of EPS material is bonded together

Nowadays, hot melt adhesive is a kind of adhesive specially used for pasting various wood-based panel materials. It is an environmentally friendly, solvent-free thermoplastic adhesive. When the hot melt adhesive is heated to a certain temperature, it changes from a solid state to a molten state. When it is applied to the surface of the wood-based panel substrate or edge-sealing material, it cools into a solid state, bonding the material and the substrate together.
