Problems solved by technology

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 waste residue after dehydration, occupying land resources, and seriously affecting the surrounding environment.

preparation example Construction

[0030] 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.

[0031]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.

[0032] Dispersants reduce the dispersion time of raw materials, stabilize dispersions, reduce flocculation, enhance stability, enhance g...

Embodiment 1

[0045] The present embodiment provides a kind of environment-friendly latex paint with ceramic polishing waste residue as regeneration filler, by weight percentage, comprising:

[0046] Ceramic polishing waste 35%, styrene-acrylic emulsion 25%, rutile titanium dioxide 5%, fluorescent whitening agent 0.1%, propylene glycol 2.2%, alcohol ester film-forming agent 1.3%, hydroxyethyl cellulose 0.1%, anionic dispersant 0.8 %, silicone modified defoamer 0.7%, isothiazolone anticorrosion and antifungal agent 0.2%, alkali swelling thickener 0.5%, silicone modified leveling agent 0.4%, Amp-95pH regulator 0.2%, remaining water.

[0047] It is mainly made by the following methods:

[0048] Weigh the raw materials measured above, add hydroxyethyl cellulose, anionic dispersant, isothiazolone preservative, propylene glycol and 1 / 2 silicone modified defoamer, add 2 / 3 of water, at a speed of 500rpm Mix well for 5 minutes. Subsequently, the ceramic polishing waste slag, rutile titanium dioxi...

Embodiment 2

[0052] The present embodiment provides a kind of environment-friendly latex paint with ceramic polishing waste residue as regeneration filler, by weight percentage, comprising:

[0053] Ceramic polishing waste 20%, styrene-acrylic emulsion 30%, titanium dioxide 3%, ultramarine 0.1%, talcum powder 5%, calcined kaolin 5%, propylene glycol 2.5%, alcohol ester film-forming agent 1.5%, modified hydroxyethyl cellulose 0.1%, 0.7% of non-ionic dispersant, 0.6% of silicone defoamer, 0.2% of isothiazolone anticorrosion and antifungal agent, 0.5% of polyurethane thickener, 0.2% of organic amine pH regulator, and the balance of water.

[0054] It is mainly made by the following methods:

[0055] Weigh the above-measured modified hydroxyethyl cellulose, non-ionic dispersant, isothiazolone anticorrosion and anti-mold agent, propylene glycol and 3 / 4 of the silicone defoamer, add 4 / 5 of the water, at a speed of 400rpm Mix well for 10 minutes. Subsequently, the ceramic polishing waste slag, ...

Abstract

The invention provides environment-friendly latex paint taking ceramic polishing waste residues as regenerated filling and a preparation method thereof and relates to the technical field of environment protection. The environment-friendly latex paint taking the ceramic polishing waste residues as the regenerated filling is prepared from the following raw materials in percentage by weight: 10 percent to 50 percent of the ceramic polishing waste residues, 10 percent to 50 percent of emulsion, 0 to 28 percent of pigment and filling, 1 percent to 21.5 percent of an additive and the balance of water. According to the latex paint provided by the invention, resources are saved, the cost is reduced and the latex paint is safe and environmentally friendly; the latex paint has relatively good chemical and mechanical performance including acid and alkali resistance, scrubbing resistance, wear resistance and the like; the environment-friendly latex paint has a wide application range and a better application prospect. The preparation method of the environment-friendly latex paint taking the ceramic polishing waste residues as the regenerated filling comprises the following steps: after sandingand pulping the ceramic polishing waste residues, the pigment and filling, the additive and the water, adding the emulsion and blending. The method has the advantages of simple preparation technology,strong controllability and low preparation cost is suitable for large-scale production.

Description

technical field [0001] 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 [0002] 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...
