Description
Technical Field
The invention relates to the technical field of hot melt adhesives, in particular to a hot melt adhesive with quick adhesion performance and a preparation method thereof.
Background
The hot melt adhesive is a plastic adhesive, the physical state of which changes along with the change of temperature within a certain temperature range, and the chemical property of which is unchanged, is nontoxic and tasteless, and belongs to an environment-friendly chemical product. The product is solid, so the product is convenient to package, transport and store, and has no solvent, pollution and toxicity; and the production process is simple, the added value is high, the bonding strength is high, the speed is high, and the like.
The hot melt adhesive is a solid meltable polymer which does not need a solvent and contains 100 percent of moisture; it is solid at normal temperature, and is heated to melt to certain temperature to become fluid liquid with certain viscosity.
The fast operation is a great characteristic of the hot melt adhesive. The operation time of the hot melt adhesive is about 15 seconds generally, and along with the wide application of a modern production mode, namely a production line, the requirement on the operation time of the hot melt adhesive is shorter and shorter, for example, the requirement on the operation time of the hot melt adhesive for book binding and sound box manufacturing reaches about 5 seconds. This requires that the hot melt adhesive function quickly and also have a high adhesive strength, but both quick adhesion and adhesive strength are often difficult to achieve, since hot melt adhesives generally consist of polymers which are compounds having a relatively high molecular weight (generally having a weight average molecular weight of at least 10)4) After the hot melt adhesive is contacted with an adherend, rapid diffusion among molecules is difficult to realize, and even after the hot melt adhesive is completely diffused, in the cooling process, the macromolecular chains are difficult to be instantly frozen, so the bonding force is not strong, and how to solve the problem is very important for the wide application of the hot melt adhesive.
