Abstract

According to the scheme, monomers such as acrylate monomers, dibutyl itaconate copolymers and fluorine-containing vinyl silane are used as main raw materials, and the adhesive with a three-layer core-shell structure is synthesized through emulsion polymerization; according to the scheme, during preparation, firstly, the core layer monomer, the middle layer monomer and the shell layer monomer are pre-emulsified, and in the step, component selection and content of the core layer monomer, the middle layer monomer and the shell layer monomer are limited, so that the oil resistance and the water resistance of the adhesive are improved, and the high-temperature resistance of the adhesive is improved. The invention discloses an oil-resistant acrylic adhesive and a preparation method thereof, the acrylic adhesive with a core layer-middle layer-shell layer composite structure is prepared, and the adhesive has excellent high temperature resistance, excellent water resistance, excellent oil resistance, good chemical corrosion resistance and high practicability.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an oil-resistant acrylic adhesive and a preparation method thereof. Background technique [0002] Acrylic adhesives are a class of adhesives with unique properties and a wide range of applications. According to the form and application characteristics of the adhesive, it can be divided into solvent type, emulsion type, reactive type, pressure sensitive type, instant drying type, anaerobic type, photosensitive type and hot melt type. From this classification, it is not difficult to see that the application range of dienoic acid adhesives is very wide. It can be said that all metal and non-metallic materials can be bonded with acrylic adhesives, and can also be widely used in daily life and factory processing applications. [0003] Today's acrylic adhesives have poor oil resistance and water resistance, which greatly affects their practical application effect. Therefore, in orde...
