Embodiment 1

[0034] Such as Figure 1 to Figure 3 As shown, Embodiment 1 of the present invention includes the following steps:

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

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

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

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

[0039] (5) Slowly drip 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 dripping in step (5) is finished, slowly rise to room temperature within 1-2h, and continue to stir at 800-1000r / mi...

Embodiment 2

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

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

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

[0052] (4) Stir the mixed solution obtained in step (1) and step (2) at a speed of 800-1000 r / min at 0°C;

[0053] (5) Slowly drip 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;

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 homogenous or heterogeneous parts (or materials) together, and have sufficient strength after curing, collectively referred to as adhesives or Adhesives, adhesives, customarily referred to simply as glues. 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 common adhesives for common plastic-plastic, metal-metal and other materials. Therefore, it is necessary to improve this...
