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:

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, ...
