AI Technical Summary

Problems solved by technology

The first method has limited effect and is limited by the molecular structure of the curing agent
The second method needs to be carried out in the resin synthesis workshop, which not only limits the paint manufacturers who lack the synthesis workshop, but also lacks the flexibility for different application occasions of floor coatings

Abstract

The invention relates to compound epoxy flooring coating adopting the mixture of epoxide resin and modified resin as a base material and further comprising organic solvent, dispersant, wetting agent, antifoaming agent, flatting agent, scratch resistance agent, pigment and stuffing as well as reactive diluent selected according to requirements. When in use, the coating is mixed and solidified withthe components of firming agent, accelerant, etc. By regulating the content of the components, the compound epoxy flooring coating of the invention can be used for manufacturing a solvent or solvent-free autolevelling epoxy floor. The compound epoxy flooring coating of the invention has favorable over-all properties, and not only has the characteristics of high mechanical strength, favorable anti-corrosion property, high adhesive force and good wear resistance property of the epoxide resin but also has the characteristics of good weather resistance, high decorative property and hardness and shock resistance of the modified resin; and the preparation method thereof is simple and practicable, is low-cost, and is suitable for mass preparation.

Description

technical field [0001] The invention relates to paint technology, in particular to a composite epoxy floor paint based on modified resin and a preparation method thereof. Background technique [0002] At present, floor coatings have gradually been recognized and accepted by the majority of users, and are widely used in hospitals, parking lots, basements, sports fields, pharmaceutical factory workshops, apartments and other civil and industrial buildings and facilities. [0003] According to the classification of film-forming substances, floor coatings can be divided into inorganic, polyurethane, polyurea, acrylic, epoxy and other types. Each floor coating has its advantages and disadvantages. For epoxy floors, there are defects such as poor acid resistance and weather resistance, brittle and easy to crack, and no impact resistance. [0004] The current solution is to use the flexibility of the curing agent to modify, and the second is to use chemical modification to redesi...
