Problems solved by technology

In the existing liquid organic coating process, the main process flow is: pre-sand blasting treatment - high pressure airless spraying - coating curing - coating inspection - finished product, these main processes, but the liquid coating Due to the solvent volatilization during curing, many coating micro-defects and coating structure are not dense, and the surface finish is poor, which cannot meet the needs of long-term heavy-duty anti-corrosion coating performance.

Embodiment Construction

[0021] The coating process of the special modified solvent-free epoxy paint for FRP of the present invention will be further described below.

[0022] The coating process of the specially made modified solvent-free epoxy coating for FRP of the present invention comprises the following steps successively:

[0023] 1) Substrate surface treatment: Before starting surface treatment, it is necessary to check whether there are welding slag, burrs, loose scale, corrosion products, old coatings, oil, grease and other deposits on the surface. Treatment, surface pre-treatment can be done by solvent cleaning, hand or power tools or other cleaning methods. After cleaning, the surface should be inspected again to ensure that any harmful residue can be easily removed in the next blast cleaning operation. ;

[0024] According to the spraying (throwing) derusting method and abrasive requirements stipulated in ST / T0407, the surface of the steel pipe is sprayed (throwing) to derust with sand. ...

Abstract

The invention relates to a coating process for a special modified solvent-free epoxy coating for glass reinforced plastic. The coating process for a special modified solvent-free epoxy coating for glass reinforced plastic comprises the following steps of: (1) treating the surface of a substrate; (2) formulating the coating and preparing materials; (3) coating a primer coating; (4) coating an intermediate coating, applying a glass fibre cloth and coating an surface coating; and (5) curing an anti-corrosion coating. The coating process disclosed by the invention is applicable to the construction in the environment at a temperature of higher than 10 DEG C and has a wide range of application environment; moreover, a professional production line is adopted for spray-coating and brush-coating, the coating quality is controllable and the requirements on the performances of long-acting anti-corrosion coating can be satisfied.

Description

technical field [0001] The invention relates to a coating process of a special modified solvent-free epoxy coating for glass steel. Background technique [0002] Fiberglass reinforced plastics (FRP), also known as GRP, are fiber reinforced plastics, generally referring to glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix. Reinforced plastics made of glass fiber or its products are called glass fiber reinforced plastics, or FRP. Due to the different types of resin used, it is called polyester FRP, epoxy FRP, and phenolic FRP. Lightweight and hard, non-conductive, high mechanical strength, less recycling, corrosion resistance. It can replace steel to manufacture machine parts, automobiles, ship shells, etc. In the existing liquid organic coating process, the main process flow is: pre-sand blasting treatment - high pressure airless spraying - coating curing - coating inspection - finished product, these main processes, but the liquid coating...
