Abstract
The present invention discloses an adhesive preparation method which is composed of steps such as mixing, preparing, etc. for rubber, acetone, ethyl acetate, epoxy resin and rosin according to a certain proportion and order. Adhesives prepared by the method can be used for the adhesion of metal, and the shearing strength and adhesion can respectively achieve 350MPa and 20000MPa. S.
Description
Technical field
The present invention relates to a kind of preparation method of tackiness agent.
Background technology
Shearing resistance that is used for tackiness agent bonding between the metal and the viscosity used on the current market are lower, and as AB glue, its shearing resistance is about 50MPa, and the about 5000MPaS of viscosity is difficult to satisfy industrial requirement to adhesive shear strength and viscosity.
Summary of the invention
The purpose of this invention is to provide a kind of preparation method with tackiness agent of high shear strength and viscosity.
Technical scheme of the present invention comprises the following steps:
A. sodium butadiene rubber or cis-1,4-polybutadiene rubber and acetone were made the epoxy glue solid by weight 10: 1,
B. ethyl acetate and acetone were made into mixed solution by weight 2: 1,
C. the epoxy glue solid with weight percent (10～25) % is dissolved in the ethyl acetate of weight percent (15～25) % and the mixed solution of acetone,
D. the Resins, epoxy with weight percent (25～30) % is dissolved in the ethyl acetate of weight percent (5～15) % and the mixed solution of acetone,
E. the solution of c, d two steps being made mixes, and adds the rosin liquation of (0.1～0.2) % weight, adds the mixed solution of weight percent (4.8～44.8) % ethyl acetate and acetone again, stirs.
The present invention is simple to operate, and the constant product quality of producing can be made the tackiness agent that shearing resistance and viscosity reach 350MPa and 20000MPaS respectively, can satisfy industrial requirement to adhesive shear strength and viscosity.
Embodiment
Embodiment one: it is standby that rubber and acetone were made the epoxy glue solid by weight 10: 1.Ethyl acetate and acetone were made into mixed solution by weight 2: 1 standby.I) the epoxy glue solid with weight percent 10% is dissolved in the ethyl acetate of weight percent 15% and the mixed solution of acetone, and ii) the Resins, epoxy with weight percent 25% is dissolved in the ethyl acetate of weight percent 5% and the mixed solution of acetone.With i), ii) the solution made of two steps mixes, the rosin liquation of 0.2% weight will be added, the mixed solution that adds weight percent 44.8% ethyl acetate and acetone again stirs and made it even in 24 hours, obtains the caking agent that golden transparent there is no visible impurity and suspended substance.This tackiness agent solidifies the back shearing resistance and viscosity is respectively 250MPa and 28000MPaS.Step c all refers to the proportion of each composition in all components total amount to the described weight percent of step e, at two following embodiment too.
Embodiment two: it is standby that rubber and acetone were made the epoxy glue solid by weight 10: 1.Ethyl acetate and acetone were made into mixed solution by weight 2: 1 standby.I) the epoxy glue solid with weight percent 18% is dissolved in the ethyl acetate of weight percent 20% and the mixed solution of acetone, and ii) the Resins, epoxy with weight percent 28% is dissolved in the ethyl acetate of weight percent 10% and the mixed solution of acetone.With i), ii) the solution made of two steps mixes, the rosin liquation of 0.1% weight will be added, the mixed solution that adds weight percent 23.9% ethyl acetate and acetone again stirs and made it even in 24 hours, obtains the caking agent that golden transparent there is no visible impurity and suspended substance.This tackiness agent solidifies the back shearing resistance and viscosity is respectively 356MPa and 22000MPaS.
Embodiment three: it is standby that rubber and acetone were made the epoxy glue solid by weight 10: 1.Ethyl acetate and acetone were made into mixed solution by weight 2: 1 standby.I) the epoxy glue solid with weight percent 25% is dissolved in the ethyl acetate of weight percent 25% and the mixed solution of acetone, and ii) the Resins, epoxy with weight percent 30% is dissolved in the ethyl acetate of weight percent 15% and the mixed solution of acetone.With i), ii) the solution made of two steps mixes, the rosin liquation of 0.15% weight will be added, the mixed solution that adds weight percent 4.85% ethyl acetate and acetone again stirs and made it even in 24 hours, obtains the caking agent that golden transparent there is no visible impurity and suspended substance.This tackiness agent solidifies the back shearing resistance and viscosity is respectively 200MPa and 25000MPaS.
