Problems solved by technology

However, when the existing water-based epoxy floor coatings are used as maintenance and repair materials, there will be obvious joints between the original coating surface and the newly repaired coating surface, and the cracking resistance and flexural strength of the repaired position will and compressive strength are not ideal, and the service life is relatively short

Embodiment approach

[0021] (1) The water-based epoxy curing agent preferably adopts a water-dilutable amine curing agent that does not contain surfactants, for example: the amine curing agent that can adopt the model produced by Air Chemical Company is AN721; this water-based epoxy Oxygen curing agent has good compatibility with epoxy resin, and can be cured at room temperature or at high temperature, and the coating formed by this water-based epoxy curing agent and epoxy resin after curing has high hardness. , Excellent adhesion, wear resistance, scrub resistance, chemical corrosion resistance, mildew resistance, etc.

[0022] (2) The water-based epoxy floor coating uses high-grade cement, coarse quartz sand and fine quartz sand mixed in a specific ratio, and both the coarse quartz sand and the fine quartz sand are made of pure natural high-strength quartz sand, so the water-based epoxy floor coating The final coating formed by epoxy floor coatings has good overall strength.

Embodiment 1

[0034] A kind of this waterborne epoxy floor paint, adopts following preparation method to make:

[0035] Step A1. According to the ratio of high grade cement: coarse quartz sand: fine quartz sand: water reducer: defoamer: cellulose = 30:20:50:0.1~0.2:0.1~0.3:0.1~0.3 in parts by weight, Weigh high grade cement, coarse quartz sand, fine quartz sand, water reducer, defoamer and cellulose respectively, and mix high grade cement, coarse quartz sand, fine quartz sand, water reducer, defoamer and cellulose Put them into a dry powder mixing tank and mix evenly to obtain the third component; wherein, the high-grade cement is No. 325 cement, and the coarse quartz sand is quartz sand with a particle size between 40 and 80 meshes. The fine quartz sand is quartz sand with a particle size of 80-120 mesh.

[0036] Step B1. According to the ratio of water-based epoxy curing agent: bisphenol A liquid epoxy resin: the third component = 1.2:1:7 in parts by weight, respectively weigh water-base...

Abstract

The invention discloses an aqueous epoxy coating for terraces, and a preparation method thereof. The aqueous epoxy coating for terraces comprises 1.2-1.3 parts of an aqueous epoxy curing agent, 1 part of bisphenol A liquid epoxy resin, and 7-8 parts of a third component, wherein the third component is prepared through mixing 20-30 parts of high grade cement, 15-20 parts of coarse quartz sand, 40-50 parts of fine quartz sand, 0.1-0.2 parts of a water reducer, 0.1-0.3 parts of an antifoaming agent and 0.1-0.3 parts of cellulose. The aqueous epoxy coating for terraces, disclosed in the embodiment of the invention, has good strong acid, strong alkali, wear, pressure, impact, mildew, water, dust and skid resistance, has the advantages of simple preparation method and long service life, avoids obvious connection seams between an original coating layer and a new repairing coating layer as a maintaining and repairing material, and keeps good cracking resistance, flexural strength and compressive strength in the repairing position.

Description

technical field [0001] The invention relates to the field of floor coatings, in particular to a water-based epoxy floor coating and a preparation method thereof. Background technique [0002] Floor coatings are floor decoration materials that use epoxy raw materials as the main agent and add pigments, solvents, additives, and curing agents. Traditional floor coatings mainly include solvent-based epoxy floor coatings and solvent-free epoxy floor coatings; solvent-based epoxy floor coatings contain more organic solvents, which not only pollute the environment, but also endanger human health; solvent-free epoxy floor coatings Epoxy floor coatings contain a small amount of reactive diluent, and the commonly used reactive diluent is butyl glycidyl ether, which has certain toxicity. [0003] Waterborne epoxy floor coating is an environmentally friendly floor coating that has emerged in recent years. It not only has many advantages such as good physical and mechanical properties, ...
