Abstract
The invention relates to a method for preparing an epoxy floor coating by taking desulfurized gypsum as filler. The epoxy floor coating is characterized by comprising a main agent A and a curing agent B which are mixed at the ratio of 3:1, wherein the main agent A comprises the following components in parts by weight: 35-45 parts of epoxy resin, 5-8 parts of activated thinner, 12-20 parts of toughening agent, 1-4 parts of pigment, 2-5 parts of auxiliaries and 25-35 parts of filler. The curing agent B is selected from polyamine, polyamide or modified aromatic amine; the auxiliaries include a defoaming agent, a flatting agent and a dispersing agent; the filler is desulfurized gypsum. A preparation method of the main agent A in the coating comprises the following steps of firstly, adding epoxy resin; then, respectively adding thinner, pigment, the wetting dispersing agent, the deforming agent and other auxiliaries; finally, adding filler (desulfurized gypsum), stirring, and then, uniformly grinding on a three-roller grinding machine to obtain the main agent A which is uniform in color and luster and free of solid sediments. A floor paved by using the epoxy floor coating prepared by taking desulfurized gypsum as filler has the advantages of high strength, wear resistance, no seams, good chemical reagent resistance, corrosion resistance, convenience in maintenance, low price and the like.
Description
Technical field
The present invention relates to a kind of method of making epoxy flooring coating taking desulfurated plaster as filler.
Background technology
Epoxy resin is usually attended by volumetric shrinkage to a certain degree in solidification process, this volumetric shrinkage easily makes epoxy resin cause stress cracking as liquid molding material, in order to improve the volumetric shrinkage of epoxy resin, reduce stress cracking, common way is that a large amount of fillers is joined in epoxy resin.Filler add in right amount physical strength and the wear resistance that can not only improve coating, but also volumetric shrinkage can reduce epoxy resin cure time and reducing costs, and give coating good storage stability energy, and the kind of filler, characteristic, consumption will produce significant impact to the performance of epoxy self-leveling floor coating.
Along with social progress, industrial expansion gives off a large amount of SO such as heat power station, Steel Plant, smeltery, glasswork, bulky refuse incinerator and various chemical plant etc. in burning or heavy oil process
2factory more and more, people are also more and more stronger to the consciousness of environment protection.In order to reduce SO in air
2content, flue gas desulfurization technique arises at the historic moment, and is widely used in various discharge SO
2factory.And reducing SO in air
2time, produce a lot of industrial by-products-desulfurated plasters.China's desulfurated plaster output is rapidly increased to 5230 tons in 2010 by 5,000,000 tons in 2005, according to the prediction of China Power News Network, desulfurated plaster annual production had reached 8,000 ten thousand tons in recent years.Meanwhile, the utilization ratio of desulfurated plaster is but very low, only only has 30%, and a large amount of desulfurated plasters are stacked or fill out sea, not only take a large amount of soils, and the sulphur taking off gets back to again ground, causes secondary pollution.Therefore comprehensive development and utilization desulfurated plaster, the utilization ratio that improves desulfurated plaster just seems to have meaning.
The present invention, using desulfurated plaster as epoxide terrace filler, had both accomplished comprehensive utilization of resources, can increase again economy of power plant benefit; Make terrace filler with desulfurated plaster, good dispersity, addition is large, and tinting strength is stronger, can also reduce the production cost of epoxide terrace simultaneously, improves the performance of enterprises.
Summary of the invention
Epoxy flooring coating taking desulfurated plaster as filler of the present invention is mainly made up of host A and solidifying agent B, and the ratio of host A and solidifying agent B is 3:1; When storage, A and B seal respectively preservation, before use A are mixed with B, stir and can use.
Host A comprises following component (by weight, taking epoxy resin as reference):
35～45 parts of epoxy resin;
5～8 parts of reactive thinners;
12～20 parts of toughner;
1～4 part of pigment;
2～5 parts of auxiliary agents;
25～35 parts of fillers;
Wherein, auxiliary agent is defoamer, flow agent and dispersion agent;
Wherein, filler is desulfurated plaster;
Solidifying agent B can select polyamines, polymeric amide or modified aromatic amine, 1/3rd left and right that its consumption is host.
The preparation of coating host A: first the epoxy resin of taking-up is put in container, add respectively the auxiliary agents such as thinner, pigment, wetting dispersing agent and defoamer, finally add filler (desulfurated plaster), after stirring, on three-roll grinder, grind evenly, obtain color and luster homogeneous, host A without solid settlement.
the advantage of the epoxy flooring coating taking desulfurated plaster as filler of the present invention is as follows:
Make terrace filler with desulfurated plaster, have good dispersity, addition is large, tinting strength is stronger, source is abundant, cheap, is beneficial to the advantages such as construction, and the waste residue of power plant desulfurization generation can be turned waste into wealth, accomplish comprehensive utilization of resources, can increase again economy of power plant benefit.
Embodiment
Below in conjunction with example, the present invention is described in further detail:
The epoxy flooring coating taking desulfurated plaster as filler of inventing is mainly made up of host A and solidifying agent B, and the ratio of host A and solidifying agent B is roughly 3:1;
Host A comprises following component (by weight, taking epoxy resin as reference):
40 parts of epoxy resin;
5 parts of reactive thinners;
15 parts of toughner;
3 parts of pigment;
2 parts of auxiliary agents;
Wherein, epoxy resin is selected E51.
Wherein, auxiliary agent is defoamer.
Wherein, filler is desulfurated plaster.
Solidifying agent B selects polyamines, polymeric amide or modified aromatic amine, and consumption is 33 parts.
The preparation of coating host A: first the epoxy resin of taking-up is put in container, add respectively the auxiliary agents such as thinner, pigment, wetting dispersing agent and defoamer, finally add filler (desulfurated plaster), after stirring, on three-roll grinder, grind evenly, obtain the host A of color and luster homogeneous.
Lay before terrace, add solidifying agent B in host A, mixing and stirring, just can carry out various terraces according to job specifications afterwards and lay.
When mixing epoxy flooring coating host A, order of addition(of ingredients) is to also there being certain influence the set time of material.If order of addition(of ingredients) is unreasonable, not only can affect the mixing time of material, also can affect the set time of material, even can affect the quality of material.Reasonably order of addition(of ingredients) is: first adding epoxy resin, is then various additives, pigment afterwards, filler.When laying, finally add solidifying agent B.
the technical indicator of the terrace that epoxy flooring coating is laid that is filler with desulfurated plaster is as follows:
