Problems solved by technology

[0002] It is well known that the medium with strong acid/alkali at a certain temperature, due to the very harsh corrosive environment, ordinary epoxy coatings are often unable to withstand, and the coating is prone to blistering and peeling during a short service period, which affects the corrosion resistance effect, shorten the service life of storage tanks, pipelines and other equipment. At present, for coatings that are stored, transported, and exposed to a series of strong corrosive media such as strong acids and strong alkalis, novolac epoxy resins with higher cross-linking density are used for protection.

preparation example Construction

[0050] A kind of preparation method of the novolac epoxy paint with chemical medium resistance performance, the concrete operation steps of described method are:

[0051] (1) Preparation of component A:

[0052] a. Add novolak epoxy resin and modifier in proportion to the container, stir and mix evenly;

[0053] b. Add coupling agent and defoamer in proportion in turn under stirring, stir and mix evenly;

[0054] c. Then add modified fillers in proportion under stirring, stir at high speed with a high-speed mixer to reach a fineness of 50-100um, and then add functional thixotropic agent and solvent;

[0055] d. After being uniformly dispersed at high speed, it can be made into component A in the coating;

[0056] (2) Preparation of component B:

[0057] Mix the amine curing agent and solvent in component B according to a certain ratio and stir evenly to make component B of the acid and alkali resistant coating;

[0058] The novolac epoxy coating is obtained after mixing th...

Abstract

The invention discloses phenol aldehyde epoxy paint with lasting electrical conductivity and a preparation method thereof, and belongs to the paint field. The phenol aldehyde epoxy paint comprises a component A and a component B, wherein the component A consists of the following components in percentage by mass of 20-60% of epoxy resin, 3-20% of phenol aldehyde epoxy functional modifier, 3-15% of reaction type epoxy diluents, 4-25% of solvent, 0.1-1% of anti-foaming agent, 2-10% of rust-proof pigment, 0.1-2% of coupling agent, 0.5-3% of functional thixotropic agent, 25-67% of modifying filler; the component B consists of the following components in percentage by mass of 97-99.5% of amine curing agents, 0-20% of solvent, 0.5-3% of coupling agent. Mass solids of the phenol aldehyde epoxy paint disclosed by the invention are over 95%, so that solid content is high; moreover, the rust-proof pigment is partly added for being used as rust-proof paint, and therefore, the phenol aldehyde epoxy paint has relatively good fog mist resistance and seawater resistance, satisfies interior-exterior anticorrosive coating, and the like of the conventional ship industry and the chemical plant, has relatively high performance for resisting chemical media such as acid-base, and the like, and particularly has thermal acid-base resistance.

Description

【Technical field】 [0001] The invention belongs to the field of coatings, and relates to a novolac epoxy coating with chemical medium resistance and a preparation method thereof. 【Background technique】 [0002] It is well known that the medium with strong acid / alkali at a certain temperature, due to the very harsh corrosive environment, ordinary epoxy coatings are often unable to withstand, and the coating is prone to blistering and peeling during a short service period, which affects the corrosion resistance The effect is to shorten the service life of storage tanks, pipelines and other equipment. At present, for coatings that are stored, transported, and exposed to a series of strong corrosive media such as strong acids and strong alkalis, phenolic epoxy resins with higher cross-linking density are used for protection. [0003] After the recent promulgation and implementation of SY / T 0319-2012 "Technical Standards for Internal Anticorrosion Layers of Liquid Coatings for Ste...
