Embodiment Construction

[0022] A solvent-free epoxy floor coating, the component A is composed of novolak epoxy resin, plasticizer, low molecular weight epoxy resin, reactive diluent, pigment and filler, dispersant, anti-settling agent, leveling agent, light yellow ; Part B is composed of cashew nut shell modified phenalkamine and modified alicyclic amine composite curing agent, pigments and fillers, reddish brown; does not contain organic solvents, and the solvent-free epoxy antirust coating is composed of Part A and Group B The points are combined according to the weight ratio of 6:1, in which:

[0023] The formula of component A by weight is:

[0024] (1) Novolac epoxy resin: 15-20 parts

[0025] (2) Plasticizer: 10-25 parts

[0026] (3) Low molecular weight epoxy resin D331: 30-40 parts

[0027] (4) Active diluent: 10-15 parts

[0028] (5) Dispersant: propyl methoxy fatty acid solution BYK 1630.6-1.5 parts

[0029] (6) Non-toxic pigments and fillers: 10-15 parts of zinc phosphate, 3-8 parts ...

Abstract

The invention discloses solvent-free epoxy terrace paint. A component A is prepared from phenolic aldehyde epoxy resin, a plasticizer, low molecular weight epoxy resin, an active diluting agent, pigments and fillers, a dispersant, an anti-settling agent and a flatting agent and is faint yellow; a component B is prepared from cashew nut shell modified phenolic aldehyde amine, a modified alicyclic amine compound curing agent and pigments and fillers and is reddish brown; the solvent-free epoxy terrace paint does not contain an organic solvent; solvent-free epoxy rustproof paint is prepared from the component A and the component B according to the weight ratio of 6 to 1. The solvent-free epoxy terrace paint disclosed by the invention has the advantages that the paint has good chemical corrosion prevention performance and the problems of existing solvent-free epoxy terrace paint which the odor is heavy, the viscosity is great and the toxicity is caused are solved.

Description

technical field [0001] The invention relates to a coating, in particular to a solvent-free epoxy floor coating. Background technique [0002] Epoxy resins are widely used in adhesives, potting materials, coatings and other industries due to their excellent adhesion and resistance to chemical media corrosion. At present, the epoxy resin used in the coating industry accounts for about half of its total output, and a variety of high-performance coatings are produced. Epoxy resins are used in anti-corrosion coatings with liquid coatings accounting for the largest share, but conventional solvent-based epoxy resin coatings mostly use aromatic hydrocarbons, esters, ketones, etc. as solvents. Most of these solvents are toxic and cause more environmental pollution after volatilization. Governments all over the world have successively imposed restrictions on the content of volatile organic compounds. In view of this, powder coatings, water-based coatings, and solvent-free coatings h...
