Embodiment 1

[0034] like Figure 1 to Figure 3 Shown, in embodiment 1 of the present invention, comprise the following steps:

[0035] (1) Stir 2.62g (0.01mol) of dibromoneopentyl glycol (CSA No. 3296-90-0) and 8mL of tetrahydrofuran at 15-30°C at a speed of 200-600r / min for 10min to dissolve the reactant completely ;

[0036] (2) Add 20 mg p-toluenesulfonic acid and stir until completely dissolved;

[0037] (3) Mix 1.58g (0.01mol) of diethylene glycol divinyl ether and 12mL of tetrahydrofuran into a constant-pressure dropping funnel, and shake to dissolve completely;

[0038] (4) Stir the mixed solution obtained in step (1) and step (2) at 0°C at a speed of 800-1000r / min;

[0039] (5) Slowly drop the mixed solution of diethylene glycol divinyl ether and tetrahydrofuran obtained in step (3) into the solution obtained in step (4), at a rate of 1 drop / 5s;

[0040] (6) After the dropwise addition in step (5), slowly rise to room temperature within 1-2h, and continue stirring at a speed of...

Embodiment 2

[0049] (1) Stir 5.24g (0.02mol) of dibromoneopentyl glycol (CSA No. 3296-90-0) and 16mL of tetrahydrofuran at 15-30°C at a speed of 200-600r / min for 10min to dissolve the reactant completely ;

[0050] (2) Add 32 mg p-toluenesulfonic acid and stir until completely dissolved;

[0051] (3) Mix 3.12g (0.02mol) of diethylene glycol divinyl ether and 30mL of tetrahydrofuran into a constant-pressure dropping funnel, and shake to dissolve completely;

Abstract

The invention discloses a polymer adhesive and a preparation method thereof. The compound is obtained by taking diethylene glycol divinyl ether and dibromoneopentyl glycol as reactants, taking p-toluenesulfonic acid and tetrahydrofuran as catalysts and carrying out polymerization reaction at the temperature of 0 DEG C. The polymer adhesive has the advantages that plastics can be adhered well, metals can also be adhered well, adhesion can be implemented within 6 minutes, functions of preventing leakage, preventing water, resisting inorganic acid corrosion and the like are fulfilled, and the practicality is quite high.

Description

technical field [0001] The invention belongs to the field of polymer materials, and specifically refers to an acid-degradable polymer adhesive and a preparation method thereof. Background technique [0002] A class of organic or inorganic, natural or synthetic substances that can connect the same or two or more homogeneous or heterogeneous parts (or materials) together and have sufficient strength after curing are collectively referred to as adhesives or Adhesives, adhesives, are customarily referred to as glue for short. As an indispensable chemical product for the development of the national economy, adhesives are widely used in various fields of the national economy. Traditional adhesives mainly include water-based adhesives, solvent-based adhesives, hot-melt adhesives, and reactive adhesives. [0003] Although there are many types of existing adhesives, there are few general-purpose adhesives for the adhesion between common plastic-plastic, metal-metal and other materia...
