Embodiment

[0018] The specific preparation method is as follows:

[0019] a) Proportioning raw materials, the raw materials selected for the hot-melt environmentally friendly pressure-sensitive adhesive used in double-sided tapes include: tackifier, toughening agent, plasticizer, antioxidant and anti-aging agent; The ratio is: 40% tackifier, 20% toughening agent, 35% plasticizer, 5% antioxidant and anti-aging agent. Among them, the tackifier is hydrogenated C5 petroleum resin, which is obtained by hydrogenation modification of C5 petroleum resin; hydrogenated C5 petroleum resin is a low relative molecular weight, thermoplastic resin, which is not only safe, environmentally friendly, Moreover, it has the properties of depressurizing, increasing viscosity and improving viscosity. It is used as a tackifier in the formulation of hot-melt pressure-sensitive adhesives, which can improve the initial viscosity of the colloid and improve the wettability of the colloid; although C5 petroleum resin...

Abstract

The invention provides a hot-melt type environment-friendly pressure-sensitive adhesive for a double sticky tape and a preparation method of the pressure-sensitive adhesive. The hot-melt type environment-friendly pressure-sensitive adhesive is prepared from a tackifier, a flexibilizer, a plasticizer, an antioxidant and an antiager. The preparation method comprises the following steps of: (a) proportioning raw materials; (b) melting the tackifier; (c) preparing the adhesive; and (d) carrying out post treatment. The hot-melt type environment-friendly pressure-sensitive adhesive has a reasonable preparation process and simple implementation links, the prepared hot-melt type environment-friendly pressure-sensitive adhesive is not only transparent in color and luster, good in appearance and initial stickness, but also non-poisonous and pollution-free, and when the hot-melt type environment-friendly pressure-sensitive adhesive is stripped, a surface to be covered cannot be stuck with dirt.

Description

technical field [0001] The invention relates to a double-sided adhesive tape, in particular to a hot-melt environment-friendly pressure-sensitive adhesive used in the double-sided adhesive tape and a preparation method thereof, belonging to the technical field of adhesive tapes. Background technique [0002] Double-sided adhesive tape is a roll-shaped adhesive tape made of paper, cloth, and plastic film as the base material, and then uniformly coated with elastomer-type pressure-sensitive adhesive or resin-type pressure-sensitive adhesive on the above-mentioned base material. , adhesive, and release paper are composed of three parts. Double-sided tape is widely used in leather, stickers, stationery, office, electronics, car trim fixing, shoe industry, handicraft pasting and positioning, etc. [0003] At present, the adhesive part of double-sided tape mostly uses pressure-sensitive adhesive, and there are many types of pressure-sensitive adhesives, especially with the rapid ...
