Problems solved by technology
Although mechanized, semi-mechanized or chemical methods have been used for derusting work, the actual production is limited by various complex working conditions, and mechanical treatment equipment such as shot blasting and sandblasting cannot be used, and there is still a large amount of derusting work to be done. It is time-consuming and labor-intensive to complete manually, and its labor intensity is quite heavy
At present, the existing rust coatings are mainly phosphoric acid and organic acids, which can only oxidize the surface of the rust layer and cannot penetrate into the interior, and the paint film is easy to foam, loose or fall off.

Abstract
The invention discloses epoxy primer realizing rusty construction. The epoxy primer comprises a component A and a component B and is characterized in that the component A is prepared from ingredients in parts by weight as follows: 17.6-26.4 parts of E51 epoxy resin, 24-36 parts of 60% 601 epoxy resin, 5.6-8.4 parts of a Lite-2020 resin modifier, 2.4-3.6 parts of an epoxy based reactive diluent, 0.4-0.6 parts of polyamide wax, 0.4-0.6 parts of a dispersing agent, 8-12 parts of a pigment, 3.2-4.8 parts of tetrabasic zinc chrome yellow, 4.8-7.2 parts of zinc phosphate, 4.8-7.2 parts of aluminum triphosphate, 5.6-8.4 parts of cyclohexanone, 2.6-4.0 parts of mixed butanol, 0.4-0.6 parts of a KBM403 silane coupling agent and 0.16-0.24 parts of a leveling agent; the component B is an amine curing agent; a weight ratio of the component A to the component B is 5:1. The invention further discloses a preparation method of the epoxy primer. The surface in a non-ideal state can be directly coated with the epoxy primer; according to the epoxy primer, the limitation that common paint requires higher derusting grade is overcome, rusty coating can be realized, the coating process is simplified, and the epoxy primer can be matched with various kinds of finish paint; the epoxy primer is suitable for bottom coating of large steel products such as a bridge, a ship, a derrick, a storage tank, a pipeline and the like.
Description
technical field [0001] The invention relates to a primer and a preparation method thereof, in particular to an epoxy rusty construction primer and a preparation method thereof. Background technique [0002] At present, the widely used steel protective coatings often require a relatively thorough surface derusting treatment on the metal substrate before coating to achieve the necessary coating adhesion strength. Although mechanized, semi-mechanized or chemical methods have been used for derusting work, the actual production is limited by various complex working conditions, and mechanical treatment equipment such as shot blasting and sandblasting cannot be used, and there is still a large amount of derusting work to be done. It is time-consuming and labor-intensive to complete manually, and its labor intensity is quite heavy. At present, the existing rust coatings are mainly phosphoric acid and organic acids, which can only oxidize the surface of the rust layer and cannot pen...
