Abstract

The invention discloses a neoprene latex type adhesive, a preparation method and the application thereof. The neoprene latex type adhesive adopts acrylic esters monomers such as butyl acrylate, gadoleic acid isooctyl ester and the like as well as styrene having sufficient source and low price; styrene-acrylic emulsion is prepared by simple technique; neoprene latex is modified by the emulsion and matched with coagulator solution and other accessory ingredients, so that rubber latex type chloroprene rubber adhesive agent can be prepared; the performance of the rubber latex type chloroprene rubber adhesive agent is similar to that of the commercially available solvent-borne type chloroprene rubber adhesive agent, and the rubber latex type chloroprene rubber adhesive agent even has some indexes being superior to the indexes of the commercially available solvent-borne type chloroprene rubber adhesive agent; furthermore, the neoprene latex type adhesive has high cost performance, wide application scope as well as remarkable social and economic benefits. The neoprene latex type adhesive can meet the needs of different base materials such as a mattress, a chair, a couch, a sofa, a screen, a handbag, industrial polyfoam and the like, is low in cost and simple in preparing method, and has the excellent properties of good storage stability, large temperciance, rapid intensity foundation, high bonding strength, etc.

Description

technical field [0001] The invention belongs to the technical field of synthetic rubber adhesives, and in particular relates to a neoprene latex adhesive and its preparation method and application. Background technique [0002] Synthetic rubber adhesives can be divided into three types according to the dosage form: solvent type, latex type and solvent-free type. Solvent-based adhesives have good process performance, strong adhesion, and stable glue, but the solvent is flammable and toxic. Latex adhesives are non-flammable and non-toxic, but their process performance and bonding performance are not as good as those of solvent-based adhesives. [0003] Neoprene adhesive is one of the largest and most widely used synthetic adhesives. However, most of them are in the form of solvents, and their application will be strictly limited as the environmental protection requirements become increasingly stringent. [0004] In order to solve the toxicity problem of solvent-based chloro...
