Abstract

The invention belongs to the field of adhesive tapes and particularly relates to a removable hot-melt pressure-sensitive adhesive tape for temporary fixation. The removable hot-melt pressure-sensitive adhesive tape for the temporary fixation comprises a base material and a hot-melt pressure-sensitive adhesive which is hot-molten and coated on the base material, and is characterized in that the hot-melt pressure-sensitive adhesive consists of the following components in percentage by mass: 40 to 60 percent of thermoplastic rubber, 20 to 40 percent of tackifying resin, 2 to 16 percent of plasticizers and 0.1 to 4 percent of antioxidant and other aids. The tackifying resin is added when the hot-melt pressure-sensitive adhesive tape is prepared, so that the adhesion is improved, and the viscosity of the system is reduced to ensure that the coating is convenient; a plurality of kinds of plasticizers are added, so that soft segment phases (B, I, EB and EP) and a hard segment phase (PS) in elastomer rubber are softened and plasticized, and the affine application property of an adhesive tape product is improved; by using the antioxidant, an adhesive is prevented from pyrolysing and deteriorating in the heating process, so that the adhesion of an adhesive product is stable, the adhesive product can be peeled at high and low rates and can be repeatedly pasted, and the trace of adhesive residue is avoided; and a heating and molten coating process is adopted, so that the release of a volatile organic solvent and the high-temperature energy consumption of an end-of-life process are avoided, and the cost of materials is reduced.

Description

technical field [0001] The invention belongs to the field of adhesive tapes, and is mainly used for product packaging in household appliances, electronics, and packaging industries, and in particular relates to a removable temporary fixing hot-melt pressure-sensitive adhesive tape. [0002] Background technique [0003] Pressure-sensitive adhesives are a type of adhesives that are sensitive to pressure and are mainly used in the preparation of pressure-sensitive tapes. In the manufacturing and packaging of products, traditional acrylic pressure-sensitive adhesives (PSA) are usually used at present, and more organic solvents are added in the preparation process, causing pollution, and the high-temperature energy consumption of the subsequent process is high. [0004] Hot melt adhesive conforms to the environmental protection concept of no organic solvent and no pollution. With the improvement of people's environmental protection awareness, the proportion of hot melt adhesive...
