Embodiment Construction

[0016] The present invention will be further described below. A preferred embodiment of the present invention is: a kind of flexible glue with good water resistance and weather resistance described in this embodiment, and the parts by mass of each component of the flexible glue are: ethyl cyanoacetate 340- 420 parts, 260-320 parts of liquid formaldehyde, 8-15 parts of hydroquinone, 260-300 parts of dioctyl phthalate, 300-360 parts of nitrile rubber, 280-350 parts of ABS, methyl methacrylate 170-230 servings.

[0017] The preparation method comprises the following steps:

[0018] The first step: adding ethyl cyanoacetate and nitrile rubber into liquid formaldehyde for complete dissolution;

[0019] The second step: add the solution dissolved in the first step, methyl methacrylate, and ABS into the reactor and stir to carry out substitution polymerization;

[0020] The third step: add hydroquinone, react in an environment of 80-85°C for 2-2.5 hours, and keep warm at 90°C for 1...

Abstract

The invention provides flexible glue with good water resistance and weather resistance. The flexible glue is prepared from the following components in parts by mass: 340 to 420 parts of ethyl cyanoacetate, 260 to 320 parts of liquid formaldehyde, 8 to 15 parts of hydroquinone, 260 to 300 parts of dioctyl phthalate, 300 to 360 parts of nitrile rubber, 280 to 350 parts of ABS (Acrylonitrile Butadiene Styrene) and 170 to 230 parts of methyl methacrylate. After the scheme is adopted, the glue not only has very good flexibility (the glue layer can be folded by 180 degrees and is not brittle or broken), but also has water resistance and weather resistance. The application range is wide, and customer requirements are greatly met.

Description

technical field [0001] The invention relates to the technical field of glue, in particular to a flexible glue with good water resistance and weather resistance. Background technique [0002] After many existing materials are firmly bonded by "instant glue", the glue layer becomes very brittle, not water-resistant, and has poor weather resistance. Because the adhesive layer is brittle, the sticky material is easily broken and damaged. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a flexible glue with good water resistance and weather resistance. [0004] In order to achieve the above object, the technical solution provided by the present invention is: a flexible glue with good water resistance and weather resistance, the parts by mass of each component of the flexible glue are: 340-420 parts of ethyl cyanoacetate, 260-320 parts of liquid formaldehyde parts, 8-15 parts of hydroquinone, 2...
