Problems solved by technology

At present, most ship paint coating systems are bottom-middle-surface systems, with long painting intervals (24 hours), many painting passes (generally 3-5 passes), and a wide variety of paints. cause a lot of inconvenience
For example, the distribution of paint by the paint supplier is complicated, and the quantity is not easy to determine. Due to the short time of the ship maintenance process, problems are likely to occur in the production, transportation, and quantity of the supplied goods; the variety of paints can easily cause the construction party to use the wrong paint or Improper paint matching, and all of the above problems may shorten the service life of the coating, forcing the ship to dock early

Abstract

The invention discloses an epoxy universal primer for ships and a preparation method thereof. The epoxy universal primer for the ships comprises components A and components B, wherein the components A comprise the following components in percentage by weight: high molecular weight epoxy resin, low molecular weight liquid bisphenol A epoxy resin, thixotropic agent, dimethylbenzene, organic soil, wetting dispersant, titanium dioxide, carbon black, iron oxide yellow, talcum powder, feldspar powder, C9 resin, isobutyl alcohol and silane auxiliaries; the components B comprise the following components in percentage by weight: polyamide curing agent and epoxy curing accelerator; in a using process, the mixing mass ratio of the components A to the components B is (6-7) to 1. The epoxy universal primer for the ships provided by the invention can be coated to 400 microns by one step without sagging, saves coating time, can be directly matched with the original coating without a transitional layer, is simple to construct, easy to grasp, and time-saving and labour-saving.

Description

technical field [0001] The invention belongs to the field of paint chemical industry, and in particular relates to a marine epoxy-type universal primer and a preparation method thereof. Background technique [0002] As a ship is an important means of transportation, the length of each near-dock maintenance directly affects the operating cost. At present, most ship paint coating systems are bottom-middle-surface systems, with long painting intervals (24 hours), many painting passes (generally 3-5 passes), and a wide variety of paints. cause a lot of inconvenience. For example, the distribution of paint by the paint supplier is complicated, and the quantity is not easy to determine. Due to the short time of the ship maintenance process, problems are likely to occur in the production, transportation, and quantity of the supplied goods; the variety of paints can easily cause the construction party to use the wrong paint or Improper paint matching, and all of the above problems...
