Abstract

The invention discloses a formula for the production of a non-setting adhesive and a preparation method thereof. The non-setting adhesive comprises ethyl methacrylate, butyl acrylate, hydroxypropyl acrylate, hydroxyethyl acrylate, vinyl acetate, an SBS (styrene-butadiene-styrene) resin, a brominated polystyrene resin, benzoyl peroxide and ethyl acetate. The preparation method for the non-setting adhesive comprises the following steps: 1, controlling the stirring speed of a stirring paddle of a reaction vessel at 80 r / min, and the heating rate at 2 DEG C / min; 2, adding an ethyl acetate solution dissolved with the SBS resin, and an ethyl acetate solution dissolved with the brominated polystyrene resin to the reaction vessel when the temperature of the reaction vessel reaches 90 DEG C; and 3, continually keeping at a constant temperature, and reacting for 30-50 min to prepare finished products. The non-setting adhesive produced with the preparation method has the characteristics of good water resistance, good cohesion performance, uneasiness of color changing, small residual smell, aging resistance, flame retardation and low production cost.

Description

Technical field [0001] The invention belongs to the technical field of chemical engineering and relates to a self-adhesive production formula and a preparation method thereof. Background technique [0002] At present, the adhesives on the market have the disadvantages of poor stickiness, easy discoloration and yellowing, large residual odor in the product, non-flame retardant products, and high production costs. Summary of the invention [0003] The purpose of the present invention is to provide a production formula and a preparation method of a self-adhesive with low production and manufacturing cost, good sticking performance, resistance to discoloration, good flame retardancy and low residual odor. [0004] In order to achieve the above objective, a self-adhesive production formula of the present invention is made of ethyl methacrylate, butyl acrylate, hydroxypropyl acrylate, hydroxyethyl acrylate, vinyl acetate, SBS resin, brominated polystyrene resin , It is composed of benzo...
