Description
Technical Field
The invention belongs to the technical field of high-molecular adhesives, and particularly relates to an oil-seepage-resistant low-temperature-resistant high-peeling-force hot-melt pressure-sensitive adhesive and a preparation method thereof.
Background
The hot melt pressure sensitive adhesive is an adhesive which takes thermoplastic rubber as a base material, integrates the characteristics of heat collection melt adhesive and pressure sensitive adhesive, has no solvent, no pollution and convenient use. The adhesive is coated in a molten state, and can be quickly bonded by applying slight finger pressure after being cooled and hardened. At present, the hot melt pressure sensitive adhesive is widely applied to the aspects of automobiles, sanitary products, adhesive tapes, labels, medical treatment and health, surface protection films, wood processing, shoe making and the like.
In recent years, with the improvement of living standard of people, the requirements of the technical field of polymer bonding on various composite materials are higher and higher, and especially higher requirements are provided for the oil permeability resistance of hot melt pressure sensitive adhesives in the application of some paper labels. The paper material is used as a coating substrate of the hot-melt pressure-sensitive adhesive, and can easily absorb the plasticizer in the components of the hot-melt pressure-sensitive adhesive, so that the component proportion of the hot-melt pressure-sensitive adhesive is changed, and the bonding performance of the hot-melt pressure-sensitive adhesive after being stored for a period of time is unstable, such as initial adhesion, stripping force, low temperature resistance, high temperature resistance and the like. The above-described occurrence of unstable variations in adhesion properties is unacceptable for downstream product applications. If a hot melt pressure sensitive adhesive whose plasticizer does not migrate to the paper substrate is developed, it is hoped to solve the problem of unstable adhesive property.
Because the application field of the hot melt pressure sensitive adhesive is more and more extensive, the requirement on the stripping force of the hot melt adhesive is higher and higher. The hot melt pressure sensitive adhesive has the advantages that the higher peeling force can be achieved under the same adhesive coating amount, or the lower adhesive coating amount can be used for achieving the peeling force of the same level, so that the hot melt pressure sensitive adhesive is a new demand for hot melt pressure sensitive adhesive developers in the market.
In addition, with the continuous and strong market of the hot-melt pressure-sensitive adhesive, various performance requirements of the hot-melt pressure-sensitive adhesive are continuously refined, and a higher-end paper base material oil seepage resistant high-peeling force and low-temperature resistant hot-melt pressure-sensitive adhesive is needed to meet the increasingly high technical requirements of the market.
