Hot Melt Pressure Sensitive Adhesives

Abstract

The invention discloses a hot-melt pressure-sensitive adhesive, relating to the technical fields of chemistry and chemical engineering. The hot-melt pressure-sensitive adhesive comprises the following compositions in parts by weight: 30-40 parts of light-colored liquid resin, 90-100 parts of a styrene-vinylidene segmented copolymer, 4-5 parts of a mixed plasticizer, 2-5 parts of an antioxidant N-dibutylamino zinc dithiocarbamate and 9-10 parts of a filling agent. According to the hot-melt pressure-sensitive adhesive, the light-colored liquid resin is introduced as thickening agent resin, so that the disadvantages that domestic petroleum resin is high in price, and raw materials are not regenerable are solved, the use levels of a softening agent and a viscosity modifier are reduced, and the cost is further saved; furthermore, the preparation process is easily controlled, the emission of pollutant is completely avoided, the safety and the environmental friendliness are guaranteed, a green production idea is realized, and various indexes can meet various performance requirements of the hot-melt pressure-sensitive adhesive in which rosin resin is utilized as the thickening agent.

Description

technical field

[0001] The invention relates to the technical field of chemistry and chemical engineering, in particular to a hot-melt pressure-sensitive adhesive. Background technique

[0002] At present, traditional solvent-based pressure-sensitive adhesives take a long time to dry, are expensive, and seriously pollute the environment during construction, endangering the health of construction workers. Therefore, the more commonly used tackifier resins include petroleum resins, terpene resins, and polyester resins. Synthetic materials such as resins are tackifiers, but polyamide resins and polyester resins have relatively complicated production processes, and few domestic manufacturers are involved in this field, while terpene resins are based on turpentine oil, and the price is relatively high, so it is not suitable for large-scale use. Petroleum resin is the most widely used. Since petroleum is a non-renewable resource, as the supply becomes less and less, it is inevitab...
