Abstract

The invention discloses an anti-impact and anti-corrosion polyurethane protective film and a preparation method and application thereof. The polyurethane protective film is prepared from, by weight, 30-50 parts of thermoplastic polyurethane, 20-30 parts of epoxy resin E44, 20-30 parts of epoxy resin E20, 40-100 parts of plasticizer, 60-100 parts of filler and 0.2-3 parts of corrosion inhibitor. The thickness of the protective film ranges from 2 mm to 3 mm. During use, a semi-finished product is heated to 140 DEG C and melted into liquid, the liquid is sprayed to a metal component with the clean surface, and after cooling, the 2-3mm protective film is formed on the surface of the protected metal component. The anti-impact and anti-corrosion polyurethane protective film is simple in formula, low in cost, free of pollution and especially suitable for anti-impact anti-corrosion protection of metal products; the anti-impact anti-corrosion polyurethane protective film is convenient to manufacture and use, the product can be manually stripped or stripped with a tool after being unsealed for use, no residual protective film is left, and the stripped material can be reused.

Description

【Technical field】 [0001] The invention belongs to the field of polymer material production, and in particular relates to an anti-collision and anti-corrosion polyurethane protective film and a preparation method thereof. 【Background technique】 [0002] Metal raw materials and semi-finished products require subsequent processing or assembly processes. In order to avoid bumps and corrosion during transportation and storage, which will affect the appearance and performance of the equipment, the use of anti-collision and anti-corrosion protective films is the most effective solution to this problem. , the most convenient way. Thermoplastic polyurethane not only has the general characteristics of ordinary protective materials, but also has high elasticity and tensile strength, suitable adhesion and peel strength, and corrosion resistance, which can effectively protect the substrate. At the same time, as a hot-melt material, thermoplastic polyurethane does not use volatile solven...
