Abstract

The invention relates to a solid composite heavy-duty anticorrosion epoxy powder which is prepared by the following materials by weight: epoxide resin from 40 to 60 parts, flatting agent from 12 to 20 parts, curing agent from 8 to 11 parts, titanium pigment from 6 to 8 parts, imidazole from 4 to 6 parts, light calcium from 2 to 10 parts, dye from 0.6 to 0.8 share, dibutyl ester from 7 to 15 parts, sericite from 2 to 3 parts, acroid resin from 12 to 20 parts and poly-butyraldehyde from 5 to 10 parts; all the components are put into a container and are stirred evenly. Then, after the process of squeezing out, pressing tablet, wind cooling, grinding and screen separating, the product is obtained. The invention has the advantages of resistance to weather, acid, alkali, high temperature, wearing, bending and shock, and can be widely used in oil and gas pipelines, city pipe network transportation, ocean engineering, bridges and buildings, the electrical apparatus industry and the defense industry. The solid composite heavy-duty anticorrosion epoxy powder is nontoxic and environment-protective, can be recycled and reused and has long service life.

Description

Technical field [0001] The invention belongs to coatings, and particularly relates to a solid-plastic composite heavy-duty anticorrosive epoxy powder. Background technique [0002] At present, the commonly used anti-corrosion coatings include single-layer epoxy powder, three-layer structure PE anti-corrosion, and two-component double-layer epoxy powder. However, they have the following defects to varying degrees: complex process, high cost, poor impact resistance and corrosion resistance of the coating, and cracks are easy to appear. Summary of the invention [0003] The invention aims to overcome the shortcomings of the prior art and provides a solid-plastic composite heavy-duty anticorrosive epoxy powder. [0004] The solid-plastic composite heavy-duty anticorrosive epoxy powder of the present invention is composed of the following parts by weight of epoxy resin 40-60 parts, leveling agent 12-20 parts, curing agent 8-11 parts, titanium dioxide 6-8 parts, imidazole 4~ 6 parts, ...
