Abstract

The invention discloses a plastic adhesive capable of being used underwater and a preparation method of the plastic adhesive. The plastic adhesive comprises the following components: epoxy resin, liquid acrylonitrile butadiene rubber, silicon dioxide, a curing agent, a coupling agent, an accelerant, sodium tetracosyl benzene sulfonate, dimethylaminoethyl methacrylate, triethanolamine, paraffin wax, and disodium edentate. The preparation method comprises the following steps: firstly, adding the epoxy resin, the liquid acrylonitrile butadiene rubber, the silicon dioxide, the coupling agent, the accelerant, the dimethylaminoethyl methacrylate and the paraffin wax into a reaction kettle, and heating and stirring the obtained mixture for reacting, so that a mixture I is obtained; then, adding the curing agent, the tetracosyl benzene sulfonate, the triethanolamine and the disodium edentate into the mixture I, and stirring the obtained mixture for uniformly mixing; and heating the obtained mixture to 80-90 DEG C under the condition that the vacuum degree is 0.04-0.08 MPa, and carrying out a stirring reaction on the obtained mixture for 3-6 hours, so that the adhesive is obtained. The plastic adhesive disclosed by the invention can be used for a long time in underwater environments.

Description

technical field [0001] The invention belongs to the field of plastic chemical industry, and in particular relates to a plastic adhesive that can be used underwater and a preparation method thereof. Background technique [0002] Adhesive bonding refers to the technology of connecting the surfaces of homogeneous or heterogeneous objects with adhesives. It has the characteristics of continuous stress distribution, light weight, or sealing, and most of the process temperature is low. Gluing is especially suitable for the connection of different materials, different thicknesses, ultra-thin specifications and complex components. Glue is developing the fastest in modern times and has a wide range of application industries. There are many classification methods of adhesives, which can be divided into thermosetting type, hot melt type, room temperature curing type, pressure sensitive type, etc. according to the application method; according to the application object, it can be divid...
