Description

A kind of environment-friendly latex paint with ceramic polishing waste residue as regeneration filler and its preparation method

technical field

The invention relates to the technical field of environmental protection, and in particular to an environment-friendly latex paint using ceramic polishing waste residue as a regenerated filler and a preparation method thereof.

Background technique

In the field of architectural coatings, latex paint is a type of water-based paint prepared from synthetic resin emulsion as the base material by adding pigments, fillers and various additives. The preparation process is simple, the construction is convenient, and the environmental pollution is small. Its application has become more and more more favored by the market. Filler, as the body pigment of latex paint, mainly plays the role of skeleton structure and improving the performance of paint, accounting for about 20-40% of the composition of latex paint. At present, most latex paint products on the market are filled with heavy calcium carbonate, light calcium carbonate, talcum powder, wollastonite powder, sericite powder, quartz powder and other minerals. The mining and processing of these mineral raw materials have irreversible damage to the environment and natural resources.

During the grinding and polishing process of architectural ceramics, a large amount of ceramic polishing waste will be produced. In terms of dry materials, about 2.1kg of solid waste is generated for every square meter of polished tiles produced. The annual output of ceramic polishing tiles in my country has reached more than hundreds of millions of square meters, resulting in an astonishing amount of ceramic polishing waste generated every year. Due to the limitations of production technology and other issues, the large-scale recycling rate of this kind of waste residue is very low. At present, more than 90% of the waste residue has not been efficiently utilized, and most of them are simply dehydrated and then landfilled, causing potential risks to the environment. Greatly restricted the development of the ceramic industry. For example, the ceramic solid waste treatment center in a certain area dehydrates or simply treats the collected ceramic waste slurry, and then sells it as an alternative raw material for the production of building materials, including the production of gray bricks, glazed bricks, ceramic tiles, porous bricks, cement, etc. However, due to the low application ratio of waste residue and low added value of products in these ways, the overall utilization of waste residue is not large, the profit of enterprises is low, and the processing capacity is difficult to increase. This often leads to the accumulation of a large amount of dehydrated waste residue, which occupies land resources and seriously affects the surrounding environment. Therefore, the comprehensive utilization of diversified and large-scale resources of ceramic polishing waste in my country urgently needs to be solved.

An environment-friendly latex paint using ceramic polishing waste as a regenerated filler and its preparation method are described in detail below.

The embodiment of the present invention provides an environmentally friendly latex paint using ceramic polishing waste as a regenerated filler.

Preferably, ceramic polishing waste slag can be 24%, 27%, 31%, 36%, emulsion can be 28%, 25%, 22%, 20%, pigment and filler can be 5.5%, 8.5%, 10.5%, 14.2% , the additive can be 8.6%, 12.2%, 8.7%, 5.5%.

Table 1 Ceramic polishing waste residue chemical composition (%)

Table 2 Ceramic polishing waste phase composition (semi-quantitative %)

It can be seen from Table 1 and Table 2 that the ceramic polishing waste slag provided by the present invention mainly contains chemical components such as silicon oxide and aluminum oxide, and its main crystal phase substance is quartz. The ceramic polishing waste itself is a ceramic material containing a crystal phase after a high temperature treatment of more than 1,000 degrees, with high hardness, high strength, and stable physical and chemical properties. After the grinding and polishing process of the ceramic production process, the particle size of the obtained waste residue is small. According to the statistical results of particle size analysis, in terms of volume percentage, 90% of the particles in the ceramic polishing waste slag have a particle size of not more than 50-120 microns, 50% of the particles have a particle size of not more than 30-50 microns, and 10% of the particles have a particle size of not more than 1 ~10 microns, the average particle size is 10-50 microns. The specific surface area is greater than 800m ² /kg, and the whiteness is between 80 and 92.

Ceramic polishing waste is used as a filler for latex paint. After the sanding process prepared by latex paint, the polishing slag particles are easy to be further refined and homogenized into a flat and smooth sheet structure, and the particle size dispersion is reduced. The flaky structure helps the latex paint to form a film and cover the active surface, prevent the latex paint from chapping, delay pulverization, improve the strength and hardness of the latex paint, and make it resistant to acid and alkali, scrubbing, abrasion and other chemical and mechanical properties be enhanced. Moreover, the ceramic polishing waste itself is alkaline, which is beneficial to the stability of the latex paint system, and the produced latex paint has a good application prospect.

The microscopic morphology test is carried out on the ceramic polishing waste slag and its sanding slurry particles provided by the invention. As can be seen from Fig. 1 and Fig. 2, the original ceramic polishing waste slag provided by the present invention is an irregular amorphous class sheet structure; as can be seen from Fig. 3, the ceramic polishing waste slag provided by the present invention is uniform after 20min sand grinding, and its particles are surface Flat and smooth flaky structure. Compared with the spherical and needle-like structures, the flaky structure is conducive to the latex paint to form a film and cover the action surface, prevent the latex paint from chapping, delay pulverization, and help to improve the strength and hardness of the latex paint, improve performance, and expand applications scope.

Emulsion has a direct impact on the quality of latex paint. Emulsion plays a role in increasing the strength of the paint and improving the number of times of scrubbing resistance in latex paint. In the present invention, the types and proportions of the emulsion, ceramic polishing waste residue and additives are studied through experiments, so that the compatibility of the raw materials is good, and the performance of the prepared latex paint is good. In the embodiment of the present invention, styrene-acrylic emulsion, pure acrylic emulsion and silicon-acrylic emulsion are mainly used.

Pigments and fillers are an important part of latex paint. In order to meet different needs, latex paint has a variety of colors, and pigments need to be added to the latex paint to give different colors and play the role of decoration and protection. In this embodiment, the pigments include conventional inorganic or organic pigments such as titanium dioxide, fluorescent whitening agent, ultramarine blue, phthalocyanine blue, and zinc chrome yellow, used singly or in combination.

Fillers, also known as extender pigments, can reduce the use of expensive pigments and reduce costs, while increasing coating strength and improving coating performance. Commonly used latex paint fillers are mainly heavy calcium carbonate, light calcium carbonate, wollastonite powder, sericite powder, quartz powder and other mineral fillers. Since mining and processing of mineral fillers will damage the environment and natural resources, the present invention uses ceramic polishing waste slag to replace mineral fillers. When other commonly used mineral fillers are appropriately reduced and replaced by ceramic polishing waste residue, the performance of latex paint can be enhanced. In the present invention, mineral fillers include talcum powder, calcined kaolin, mica powder, heavy calcium carbonate and light calcium carbonate, etc., used singly or in combination.

In the preparation process of latex paint, different additives are added according to actual needs to achieve the required properties. In a preferred embodiment of the present invention, the additives include any one or at least two of thickeners, dispersants, defoamers, anticorrosion and antifungal agents, film-forming aids, leveling agents, and pH regulators.

As an important additive in latex paint, thickener is mainly used to improve and increase the viscosity of latex paint, maintain a certain rheology, prevent sagging during construction, and endow latex paint with excellent mechanical properties and storage stability. . In the embodiment of the present invention, the thickeners are selected from polyurethane thickeners, alkali-swellable thickeners, and cellulose thickeners, etc., and are added singly or in combination.

Dispersants reduce the dispersion time of raw materials, stabilize dispersions, reduce flocculation, enhance stability, enhance gloss, and increase color development. In an embodiment of the present invention, the dispersant includes anionic dispersant, nonionic dispersant, hydrophobic dispersant and the like.

When latex paint is used in construction and other aspects, it needs to have anti-corrosion and anti-mildew properties, so as to avoid the corrosion of the coating body by corrosive substances such as chemicals and the erosion of mold. In the embodiment of the present invention, anticorrosion and antifungal agents such as isothiazolone, benzothiazolinone and its derivatives are also included in the additives to improve the performance of the latex paint.

As one of the important additives in latex paint, film-forming aids enable latex paint to achieve construction performance and film-forming quality. The film-forming process of latex paint is relatively complicated, so that dispersed polymer particles coalesce into a whole. Film-forming aids promote the plastic flow and elastic deformation of latex particles, soften the surface of particles, and promote polymer particles to be easily deformed under pressure and fuse into films; film-forming aids can reduce the minimum film-forming temperature of emulsions and latex paints. In the embodiment of the present invention, the film-forming aids are selected from alcohol ester film-forming agents, alcohol ether film-forming agents, propylene glycol, ethylene glycol, etc., and used singly or in combination.

During the construction process, latex paint has poor leveling performance, and brush marks and orange peel will appear during brushing/spraying, and shrinkage cavities, pinholes, and sags will appear during the drying process. An effective way to overcome the disadvantage of poor leveling is to add a leveling agent. In the embodiment of the present invention, silicone modified leveling agents, acrylic leveling agents and polyurethane rheology additives are mainly used, either singly or in combination.

The pH regulator is used to adjust the pH value of the latex paint, increase the stability of the latex paint, and also has the function of wetting and dispersing. In an embodiment of the present invention, the pH regulator includes an organic amine regulator, Amp-95 pH regulator and the like.

In order to make the latex paint prepared have better mechanical properties and chemical properties, through the inventor's experimental research, the pigments and fillers include at least one of 0-8% of pigments and 0-20% of mineral fillers, and the additives include thickeners. 0.2-3.2%, 0.3-4% dispersant, 0.2-3% defoamer, 0.1-3% anti-corrosion and anti-mold agent, 0.1-6% film-forming aid, 0.1-2% leveling agent and pH regulator 0 Any one or at least two of ~0.3%.

The embodiment of the present invention also provides a preparation method of an environment-friendly latex paint using ceramic polishing waste residue as a regenerated filler, comprising:

Fully mix and stir the pre-measured 1/2-4/5 water, part of the thickener, dispersant, 1/2-3/4 defoamer, anti-corrosion and anti-fungal agent at a stirring speed of 500-800rpm 0~20min.

After stirring evenly, add ceramic polishing waste residue and pigment. In an embodiment of the present invention, mineral fillers may also be added, and dispersed at a stirring rate of 800-1500 rpm for 0-40 minutes to obtain a coarse dispersion.

Put the coarse dispersion into the sand mill and grind for 5-60 minutes, and the motor speed of the grinding chamber is 1000-3000rpm. Preferably, for sufficient grinding, the particle size of the grinding beads is 0.3-3.0 mm. The smaller the size of the grinding beads, the smaller the particle size of the grinding slurry particles. Test the fineness, preferably, the fineness is less than 40 μm, that is, a uniformly dispersed pigment and filler slurry can be obtained.

Slowly add the metered emulsion, film-forming aids, and the remaining defoamer into the slurry. Under the condition of 300-800rpm, stir at a low speed evenly, add the remaining thickener, pH regulator, and remaining water to adjust the viscosity of the system, and stir evenly to obtain a latex paint sample.
