Abstract

The invention discloses a hot-melt pressure-sensitive adhesive for refrigerator insulation materials and a preparation method of the hot-melt pressure-sensitive adhesive. The hot-melt pressure-sensitive adhesive is prepared from the following components in parts by weight: 25 to 35 parts of naphthenic oil KN4010, 10 to 20 parts of thermoplastic styrene-butadiene rubber, 3 to 9 parts of thermoplastic rubber, 20 to 30 parts of rosin resin, 20 to 30 parts of petroleum resin and 0.3 to 1 part of antioxidant. The invention further discloses the preparation method of the hot-melt pressure-sensitiveadhesive for the refrigerator insulation materials. The hot-melt pressure-sensitive adhesive for the refrigerator insulation materials, disclosed by the invention, has high initial adhesion, strippingresistance and retentivity under 40 DEG C, good weather fastness and stability and the characteristics of environment-friendliness, no solvent and the like, and compared with conventional foam double-faced adhesive tapes, the hot-melt pressure-sensitive adhesive for refrigerator insulation materials can save space.

Description

technical field [0001] The invention relates to the technical field of hot-melt adhesives, in particular to a hot-melt pressure-sensitive adhesive used as a refrigerator insulation material and a preparation method thereof. Background technique [0002] Hot melt adhesive is a new type of adhesive, which is a synthetic resin with thermoplastic plastic as the main body. When encountering high temperature (100-200°C), it begins to melt into a liquid. When it returns to normal temperature, it returns to solid again. It does not contain any solvents, is pollution-free, is green and environmentally friendly, has a simple production process, high automation when used by customers, high production efficiency, and a wide range of uses. [0003] The insulation material of the refrigerator was bonded with foam double-sided adhesive earlier. The disadvantage is that the foam double-sided adhesive needs to be glued manually, and the production efficiency is low. The thickness of the fo...
