Abstract

The acid-proof and wear-proof anticorrosive paint includes two parts, component A and component B. The component A consists of epoxy resin 40-50 weight portions, silicone resin 30-40 weight portions, carbon black 2-4 weight portions, xylene 12-22 weight portions; and the component B is curing agent of polyamide resin. The preparation process of the acid-proof and wear-proof anticorrosive paint includes the following steps: preparing component A through mixing epoxy resin, silicone resin and carbon black, adding xylene and grinding; preparing component B; and packing the component A and the component B separately. Before painting, the component A and the component B are mixed in the weight ratio of 3-5 to 1. The paint can form coating capable of resisting heat, wear, acid, alkali and corrosion and with long service life through curing at normal temperature.

Example Embodiment

[0029] Example 1

[0030] This acid-resistant, wear-resistant and heavy-duty anti-corrosion coating consists of two parts: component A and component B.

[0031] The A component is composed of epoxy resin, silicone resin, carbon black and xylene. The raw materials of the above component A include the following components and their contents by weight:

[0032] Epoxy resin 45 parts by weight Silicone resin 35 parts by weight

[0033] Carbon black 3 parts by weight Xylene 17 parts by weight

[0034] The B component is a curing agent composed of polyamide resin.

[0035] The raw materials used are all commercially available mature raw materials.

[0036] The component A and component B are prepared separately, packaged and stored separately, and mixed evenly according to 4:1 during coating construction.

[0037] The preparation method of the coating of this embodiment includes the following process steps:

[0038] The preparation method of component A is as follows:

[0039] a. Weigh the epoxy resin, silicone resin and carbon black according to the above-mentioned ratio requirements and send them to the mixer for thorough mixing.

[0040] b. Add xylene weighed according to the above-mentioned ratio into the mixture of a above and send it to a sand mill for grinding.

[0041] c. Filter the above-mentioned ground paint with a sieve and inspect the packaging for later use.

[0042] Component B is a curing agent, and the curing agent is polyamide resin.

[0043] The component A and component B are prepared separately, packaged and stored separately, and mixed evenly according to 4:1 during coating construction.

[0044] The raw materials used are all commercially available mature raw materials.

Example Embodiment

[0045] Example 2

[0046] This acid-resistant, wear-resistant and heavy-duty anti-corrosion coating consists of two parts: component A and component B.

[0047] The A component is composed of epoxy resin, silicone resin, carbon black and xylene. The raw materials of the above component A include the following components and their contents by weight:

[0052] The preparation method of the coating in this example is the same as that in example 1.

Example Embodiment

[0053] Example 3

[0054] This acid-resistant, wear-resistant and heavy-duty anti-corrosion coating consists of two parts: component A and component B.

[0055] The A component is composed of epoxy resin, silicone resin, carbon black and xylene. The raw materials of the above component A include the following components and their contents by weight:

[0056] Epoxy resin 50 parts by weight Silicone resin 30 parts by weight

[0057] Carbon black 2 parts by weight Xylene 12 parts by weight

[0058] Component B is a curing agent, and the curing agent is polyamide resin.

[0059] The A component and the B component are prepared separately, packaged and stored separately, and mixed evenly according to 5:1 during coating construction.

[0060] The preparation method of the coating in this example is the same as that in example 1.

[0061] The acid-resistant, wear-resistant and heavy-duty anti-corrosion coating prepared by the foregoing embodiments can be widely used in various corrosive environments such as environmental protection engineering, municipal construction, petrochemical engineering, ships and vehicles, ports, power facilities, oilfields and mines, and waterproofing projects, and is especially suitable for Severe corrosion and severe abrasion.

[0062] For example: the acid-resistant, wear-resistant, heavy-duty anticorrosive paint produced according to the technology of the present invention (model ZWS-T acid-resistant and wear-resistant heavy-duty anticorrosive paint) is used in the ZWS type high-efficiency wet desulfurization and dust removal device tower (mainly used for various boiler flue gas desulfurization, denitrification, and dust removal ) Anti-corrosion of swirl plate, defogging plate, flue, wind blade, etc. inside. The service life can be increased from 3 years to 5 years after corrosion protection.

[0063] The construction method of the coating of the invention can be brushed or high-pressure airless spraying, the recoating interval is 3-24h, and the curing period is 7d (>20°C).
