Quick drying and easily stripped adhesive capable of resisting rust of thread parts and preparation method of adhesive

Abstract

The present invention discloses a quick drying and easily stripped adhesive capable of resisting rust of thread parts and a preparation method of the adhesive. The adhesive consists of the following components in parts by weight: 20-35 parts of hydrogenated thermoplastic styrene-butadiene rubber, 5-10 parts of wax material, 4-10 parts of antirust material, 40-60 parts of solvent,0.5-1.0 part of lithium stearate, and 0.1-0.5 part of silicone oil, wherein the wax material is a mixture of two or three kinds of ozocerite, vaseline and liquid paraffin, and the anti-rust material is one or two of petroleum calcium sulfonate or barium petroleum sulfonate. The quick drying and easily stripped adhesive capable of resisting rust of thread parts in the invention has good coating performance and smallfluidity when coating, and can ensure that thread protruding parts are not lack of the adhesive, therefore, and the adhesive has good anti-rust effect. The adhesive has the characteristics of quick drying, no need for air drying, and capability of facilitating next step after coating; and no adhesive residue exits when peeling, good anti-rust performance is achieved, and no rust happens when thesalt spray resistance is greater than 180 hours, and the adhesive can be used for temporary storage and anti-rust protection of spare parts of aerospace and national defense equipment manufacturing.

Description

technical field [0001] The invention relates to the technical fields of adhesives and antirust, in particular to a quick-drying, easy-to-peel thread antirust glue and a preparation method thereof. Background technique [0002] The peelable protective glue is sprayed on the surface of the object to form a layer of peelable transparent film, which can effectively isolate the object through the film, so as to achieve the state of anti-dirty, anti-rust, anti-acid and alkali, anti-scratch and tear-off. It is widely used in chemical industry, machinery, electronics, textile, packaging and other industries. But at present, the existing peelable protective adhesives on the market are mostly perchlorethylene, polyvinyl butyral or acrylic esters. These types of peelable protective adhesives are brittle, have low tensile strength, are not easy to peel and remove, and can The bottom is easy to break, it is difficult to remove, the coating is poor, the coating is fluid, the protruding p...

Problems solved by technology

But at present, the existing peelable protective adhesives on the market are mostly perchlorethylene, polyvinyl butyral or acrylic esters. These types of peelable protective adhesives are brittle, have low tensile strength, are not easy to peel and remove, and can The bottom is easy to break, it is difficult to remove, the coating is poor, the coating is fluid, the protruding parts of the thread are prone to lack of glue, and the threaded parts are easily left behind after stripping the threaded parts. Therefore, these types of glue are antirust to the metal surface, especially the protruding part of the thread Poor performance, which increases the follow-up processing work of threaded parts, and cannot meet the requirements of easy peeling and high performance antirust

In addition, the current peelable protective adhesive has high requirements on the use environment. When used at low temperature, the adhesive film becomes brittle and difficult to remove. The drying time is long, and the tensile strength and elongation of the thread antirust adhesive film after drying are both smaller
