Technical Field
The invention relates to the technical field of building coating preparation, in particular to an epoxy mortar coating and a preparation method thereof.
Background
The water-based epoxy floor is formed by constructing water-based epoxy resin coatings such as primary coating, middle coating and top coating. The intermediate coating is also called as surfacer and surfacer. After the coated object is coated with primer and the putty is filled, the coated object is polished by abrasive paper to be flat, and before the finish paint is coated, a transition layer is usually coated as an intermediate coating. The intermediate coating has the characteristics of good filling and leveling property, low paint film strength, easy polishing and the like, and is used for priming when the requirement on surface decoration is higher.
Compared with wall coatings, the waterborne epoxy floor needs to have certain bearing capacity, and therefore, a certain proportion of inorganic curing agent needs to be added in the waterborne epoxy floor in an auxiliary mode, so that the mechanical strength of the floor is improved. Most epoxy middle coatings in the market at the present stage can only be added with some talcum powder, quartz powder and double-flying powder, and after the portland cement is added, the portland cement destroys the interface property of the epoxy coating, so that the serious demulsification phenomenon occurs and the epoxy middle coating cannot be normally used. In addition, some water-based epoxy resin coatings have the problems that even if the emulsion breaking defect does not occur in the early stage, thick coating cracks seriously and the like occur in the later stage, namely, the cracks occur when the film thickness is more than 800 UM.
Disclosure of Invention
In order to solve the technical problems, the invention provides the epoxy mortar coating and the preparation method thereof, and the problems of demulsification and cracking after the addition of the portland cement are solved by adjusting the formula components and the ratio of the components.
In order to achieve the purpose, the invention adopts the following technical scheme:

and B component: 85-95 parts of epoxy resin and 5-15 parts of aliphatic glycidyl ether;
and C, component C: 80-100 parts of quartz sand, 20-40 parts of Portland cement, 0.5-1.5 parts of wood fiber and 1-3 parts of PP fiber.
Preferably, the portland cement is 325 slag portland cement, i.e., early strength type slag portland cement representing a strength grade of 32.5. The slag portland cement has light color, small specific gravity, lower hydration heat, and better corrosion resistance and heat resistance than ordinary portland cement. The addition of a small amount of 325 slag portland cement can not affect the color of the terrace, can improve the performances of corrosion resistance, wear resistance, heat resistance and the like of the terrace, and can not cause the demulsification defect of the coating.
As a further improvement of the invention, the aliphatic glycidyl ether has a viscosity of 3-7 mpa.s at 40 ℃ and an epoxy equivalent of 290-310 g/eq.
As a further improvement of the invention, the dispersant is 750W or BYK 190; the epoxy resin is low molecular weight epoxy resin, and the concentration of the epoxy resin is 85-95%.
As a further improvement of the invention, the defoaming agent is one or a combination of BYK-028, BYK-024, SN154 defoaming agent or A10 defoaming agent.
As a further improvement of the invention, the substrate wetting agent is one or a combination of BYK346, WET510 or PW 336.
As a further improvement of the present invention, the ratio of the epoxy resin to the epoxy curing agent is 3: 1; the epoxy curing agent is Yingchuang 735W.
As a further improvement of the invention, the granularity of the quartz sand is 80-120 meshes.
As a further improvement of the invention, the epoxy resin is bisphenol A type epoxy resin. The bisphenol A epoxy resin has good physical and mechanical properties, chemical resistance and electrical insulation performance after being cured.
The second technical scheme is as follows:
a preparation method of the epoxy mortar coating comprises the following steps:
(1) uniformly mixing deionized water, a defoaming agent, a dispersing agent and a base material wetting agent to obtain slurry A;
(2) adding an epoxy curing agent into the slurry A, then adding a flatting agent, and uniformly mixing to obtain slurry B, namely the component A; (3) diluting the epoxy resin with aliphatic glycidyl ether in a clean container without deionized water, and uniformly mixing to obtain the component B.
(4) Stirring quartz sand and 325-silicate cement for 15 minutes, and then adding wood fiber and PP fiber; mixing uniformly to obtain a component C;
(5) uniformly mixing the component A and the component B, adding deionized water, wherein the water addition amount is 10-15% of the total mass of the component A and the component B, uniformly stirring again, and slowly adding the component C to obtain a finished product.
As a further improvement of the invention, the water addition amount in the step (5) is 10% of the total mass of the component A and the component B.

The bisphenol A epoxy resin has the defects of high viscosity, brittle curing property and the like, the contact part with the primer is easy to break emulsion due to the existence of stress, in order to reduce the viscosity and improve the workability and increase the flexibility of a cured product, a method of adding a plasticizer is often adopted, but the plasticizer is added to have certain influence on the performance of the cured product. The aliphatic glycidyl ether can soften PP fiber and wood fiber, can enhance the flexibility and fastness of the fiber, and can improve the tensile strength of the fiber.
The defoaming agent is used for reducing the surface tension, inhibiting the generation of foam or eliminating the generated foam.
The substrate wetting agent is used for improving the surface tension and permeability of the coating, so that the coating can better wet the ground materials, and the adhesion of the coating is improved.
The addition of small amount of wood fiber and PP fiber can improve the crack resistance of the coating.

demulsification is essentially the process of eliminating emulsion stabilizing conditions and causing dispersed droplets to aggregate and delaminate. Demulsification causes the emulsion to break completely into two immiscible phases. Demulsification of the coating is very harmful to construction. The demulsification is caused by various reasons, wherein the concentration of hydrogen ions and hydroxide ions reaches a certain degree to cause the demulsification, and particularly, alkaline substances are important reasons for the demulsification of the coating. The silicate cement is a hydraulic cementing material prepared by grinding silicate cement clinker taking calcium silicate as a main component, less than 5 percent of limestone or granulated blast furnace slag and a proper amount of gypsum. Due to the existence of weak acid strong alkali salt, the alkali is obtained after dissolving in water. While alkaline substances can cause the coating to break emulsion. This application is through adjusting the proportion between formula and each component promptly the water cement ratio, this problem has fine solution, does not influence the nature of other components in the coating after adding portland cement, and makes in the coating because added this kind of inorganic curing agent of portland cement and reached fine mechanical properties, has satisfied the intensity requirement of terrace with coating.

Wood fiber has the hole structure, can make the terrace have good heat preservation, thermal-insulated, give sound insulation, insulating and air permeability after adding wood fiber in coating, and can absorb expend with heat and contract with cold's energy, prevent to cause the phenomenon of shelling and fracture because expend with heat and contract with cold, make the terrace have better mechanical properties.
The PP fiber, namely the polypropylene fiber, is a high molecular polymer, has the excellent performances of light weight, high strength, good elasticity, corrosion resistance, aging resistance and the like, and the crack prevention effect and the mechanical property of the coating after curing can be obviously improved by adding a small amount of PP fiber into the coating. The PP fiber and the wood fiber are mixed for use, and the synergistic effect is achieved, so that the mechanical property of the coating after curing is improved to a greater extent.
According to the special epoxy mortar coating for the water-based terrace, the epoxy resin contains the functional monomer, and the amino group in the functional monomer can reduce or eliminate organic pollutants in the air, so that the indoor air quality can be improved, and the VOC is extremely low. The matching proportion of the epoxy resin and the epoxy curing agent is optimal, and the epoxy resin has good hardness and solvent resistance.
The various auxiliary agents can be any auxiliary agent adopted in the field, can be directly purchased and prepared, and can also be prepared according to a conventional preparation method.
