Problems solved by technology

Now there are a lot of low-temperature environments that need to use pressure-sensitive adhesive tapes and pressure-sensitive labels, but some pressure-sensitive adhesives have low initial adhesion and peel strength in low-temperature environments, especially in the cold winter environment in northern my country. Tapes and pressure-sensitive labels peel off easily and cannot be glued

Abstract

The invention discloses a pressure-sensitive adhesive for a low-temperature environment. The pressure-sensitive adhesive comprises a first component and a second component, the first component comprises a first acrylate compound, benzoyl peroxide and N-hydroxymethyl acrylamide, and the second component comprises a second acrylate compound, ethyl acetate, acrylic acid and benzoyl peroxide. The preparation method comprises the step of mixing and stirring the components. Through the mode, the pressure-sensitive adhesive for the low-temperature environment and the preparation method of the pressure-sensitive adhesive have the advantages that the pressure-sensitive adhesive is simple in raw material source, low in cost and easy to prepare, can be used for a long time in the environment of -50 DEG C, does not deform, fall off or warp, and ensures the adhesion effect.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a pressure-sensitive adhesive used in a low-temperature environment and a preparation method thereof. Background technique [0002] 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 has both the influencing factors and properties of being able to withstand the contact process and failure process of bonding. The pressure-sensitive adhesive can be firmly bonded to the adherend by applying a little pressure. It is mainly used to make pressure-sensitive adhesive tapes and pressure-sensitive labels. Wide range of uses. Now there are a lot of low-temperature environments that need to use pressure-sensitive adhesive tapes and pressure-sensitive labels, but some pressure-sensitive adhesives have low initial adhesion and peel strength in low-temperature environments, especial...
