preparation example Construction

[0015] A preparation method for water-based spray glue, comprising the steps of:

[0016] a take neoprene latex, rosin emulsion, C5 petroleum resin, acrylic acid emulsion, polyaziridine cross-linking agent and pH regulator by proportioning;

[0017] b Mix and stir the components weighed in step a to obtain the glue component; specifically, stir for 60 min at a stirring speed of 400r / min, and add water in step a to adjust the viscosity of the glue component according to actual needs dilution;

[0018] c mix and stir calcium chloride and water to obtain a demulsifier. Specifically, stirring for 60 min at a stirring speed of 500 r / min.

Embodiment 1

[0023] The preparation method of the water-based spray glue of embodiment 1 and comparative example 1:

[0024] a take by weighing neoprene latex, rosin emulsion, C5 petroleum resin, acrylic acid emulsion, polyethylenimine crosslinking agent, pH regulator, calcium chloride and water by proportioning, wherein pH regulator selects glycine for use, does not have in comparative example 1 C5 petroleum resin;

[0025] b Mix and stir neoprene latex, rosin emulsion, carbon five petroleum resin, acrylic emulsion and polyethylenimine crosslinking agent, adjust the pH with glycine to make the pH in the range of 9-10, and then stir at a speed of 400r / min Stir down for 60min to make water-based spray glue (A component);

[0026] c. Mix calcium chloride and water to obtain a demulsifier, and stir at a stirring speed of 500r / min for 60min to obtain a demulsifier (component B).

[0027] The A component and the B component of the water-based spray glue prepared according to the ratio of Exam...

Embodiment 2

[0028] The preparation method of the water-based spray glue of embodiment 2 and comparative example 2:

[0029] a take by weighing neoprene latex, rosin emulsion, C5 petroleum resin, acrylic acid emulsion, polyaziridine crosslinking agent, boric acid, pH regulator, calcium chloride and water, wherein pH regulator selects acetic acid for use, comparative example 2 There is no polyethylenimine cross-linking agent;

[0030] b Mix and stir neoprene latex, rosin emulsion, carbon five petroleum resin, acrylic emulsion, polyaziridine crosslinking agent and boric acid, adjust the pH with acetic acid to make the pH in the range of 9-10, and then use 400r / min Stir at a stirring speed for 60 minutes to prepare water-based glue for spraying glue (component A);

[0031] c. Mix calcium chloride and water to obtain a demulsifier, and stir at a stirring speed of 500r / min for 60min to obtain a demulsifier (component B).

[0032] The A component and the B component of the water-based spray gl...

Abstract

The invention provides adhesive for waterborne sprayable adhesive, comprising, by weight, 70-80 parts of neoprene latex, 5-10 parts of rosin emulsion, 5-10 parts of C5 petroleum resin, 5-10 parts of acrylic emulsion, 1-5 parts of polyethylenimin crosslinker, and 1-2 parts of a pH regulator. The C5 petroleum resin and the rosin emulsion in the waterborne sprayable adhesive made with the adhesive for waterborne sprayable adhesive have good compatibility, the polyethylenimin crosslinker and the acrylic emulsion can be crosslinked so that the waterborne sprayable adhesive has the advantages of high initial adhesion, high solidifying speed and the like; the problems of low initial adhesion, low solidifying speed and the like are solved which occur when waterborne sprayable adhesive is applied to rough surface materials, such as wood and leather, and smooth surface materials, such as plastics and glass fiber reinforced plastic.

Description

technical field [0001] The invention relates to the technical field of glue spraying, in particular to a glue for water-based spray glue, water-based glue spray and a preparation method thereof. Background technique [0002] Spray glue is an adhesive that can closely connect two different substances and play a role in transfer application. It is widely used in furniture, leather and decoration industries. At present, the spray glue on the market is mainly oil-based spray glue, which contains a large amount of organic solvents, such as toluene and chlorinated solvents, and even contains carcinogenic ingredients such as benzene. These organic solvents enter the air, which seriously affects people's living environment and damages people's health. Moreover, oily spray glue is also flammable and explosive, which frequently causes fires. [0003] As a water-based neoprene spray glue that can replace oil-based spray glue, it has become one of the development directions of the adhe...
