Pressure-sensitive adhesive used for cotton paper or non-woven fabrics and preparation method thereof

Abstract

The invention discloses a pressure-sensitive adhesive used for cotton paper or non-woven fabrics and a preparation method thereof. The preparation method comprises the following steps of: uniformly mixing 15 to 25 percent of butyl acrylate, 20 to 35 percent of ethyl hexyl acrylate, 0.2 to 4 percent of crylic acid, 0.5 to 2 percent of methyl methacrylate, 0.2 to 1.5 percent of vinyl acetate, 0.1 to 1 percent of 2-hydroxyethyl methacrylate and 40 to 60 percent of ethyl acetate; heating to the temperature of between 80 and 85DEG C in a reaction kettle, and adding benzoyl peroxide by 1 to 3 times in the temperature keeping process, wherein the temperature keeping time is 2 to 10 hours; and adding tackifying resin according to viscosity requirement. The pressure-sensitive adhesive prepared by the method has large stripping force of 1,000-2,000g, and ensures that the cotton paper or the non-woven fabrics are not layered in the tearing process and adverse effect cannot occur.

Description

technical field [0001] The invention relates to a pressure-sensitive adhesive used for tissue paper or non-woven fabric and a preparation method thereof, belonging to the technical field of adhesive material processing. Background technique [0002] Pressure-sensitive adhesive tape is referred to as pressure-sensitive adhesive tape, which is defined as: using finger pressure, it can make the adhesive immediately bond to the smooth surface of any adherend. At the same time, if the adhesive does not pollute the surface of the adherend when the surface of the adherend is destroyed, this type of adhesive is called a pressure sensitive adhesive (PressureSensitive Adhesive). Pressure-sensitive adhesive is a kind of viscoelastic body with both the viscous properties of liquid and the elastic properties of solid; this viscoelastic body also has "the influencing factors and properties of being able to withstand both the contact process and the destruction process of bonding" .

Problems solved by technology

[0003] At present, the high-viscosity pressure-sensitive adhesive tape has good initial adhesion and strong peeling force, but in the process of coating the double-sided adhesive tape by the two-step method, due to the poor fluidity of the adhesive after coating, the permeability to tissue paper is not good, resulting in Cotton paper is easy to delaminate during use, which has a negative impact on product performance
