Abstract

The invention belongs to the technical field of novel coating layer materials, and discloses a no-clean antirust material capable of being integrally stripped or removed by heating, a preparation method and application thereof. The preparation method comprises the following steps: mixing and homogenizing a waxy substance and a part of an alkane solvent to obtain an emulsion A; adding an elastic resin into the other part of the alkane solvent, adding an antirust agent and an interface treating agent under a stirring condition, and stirring until the antirust agent and the interface treating agent are completely dissolved to obtain a resin solution B; and mixing and homogenizing the emulsion A and the resin solution B, then adding a surfactant and a defoaming agent, homogenizing and stirring, and filtering to obtain the no-clean antirust material capable of being integrally stripped or removed by heating. According to the no-clean antirust material, the specific elastic resin and the waxy substance are compounded, the film forming state after use is a semitransparent soft film, compared with an existing oil film or a brittle paint film, the film can be removed by tearing off the whole film or heating melting / volatilizing, no chemical solvent or cleaning agent is needed for removal, and VOC emission and chemical solvent harm are remarkably reduced.

Description

technical field [0001] The invention belongs to the technical field of new coating materials, and in particular relates to a no-cleaning antirust material that can be stripped off as a whole or removed by heating, as well as its preparation and application. Background technique [0002] The problem of metal corrosion pervades all walks of life in the national economy. Metal corrosion will greatly damage the performance and commodity value of metal products, and even cause major failures and make equipment scrapped. In order to avoid corrosion, people have adopted a variety of techniques and methods to prevent the occurrence of metal corrosion. Among them, using anti-rust oil to protect metal products is one of the most common protection methods at present. [0003] Wax film anti-rust oil is a kind of anti-rust oil. Wax film anti-rust oil is a solvent-diluted anti-rust oil composed of film forming agent, high-efficiency corrosion inhibitor and base oil. Compared with other ...
