preparation example Construction
[0027] 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.
[0028] Thickeners are selected from polyurethane thickeners, alkali-swellable thickeners and cellulose thickeners, etc., added singly or in combination.
[0029] Dispersants mainly include anionic dispersants, nonionic dispersants and hydrophobic dispersants.
[0030] The additives also include anticorrosion and antifungal agents such as isothiazolone, benzothiazolinone and their derivatives to improve the stability of the latex paint.
[0031] 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 glyc...
Embodiment 1
[0042] This embodiment provides a kind of environment-friendly latex paint that uses waste ceramics as a regenerated filler, by weight percentage, including:
[0043] The waste ceramics are coarsely ground and then ground to 200 mesh, and the ground particles are taken.
[0044] Waste ceramics 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 0.6% , silicone modified defoamer 0.5%, isothiazolone anticorrosion and antifungal agent 0.2%, alkali swelling thickener 0.4%, silicone modified leveling agent 0.3%, Amp-95pH regulator 0.2%, and amount of water.
[0045] It is mainly made by the following methods:
[0046] 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 ...
Embodiment 2
[0050] This embodiment provides a kind of environment-friendly latex paint that uses waste ceramics as a regenerated filler, by weight percentage, including:
[0051] The waste ceramics are coarsely ground and then ground to 150 mesh, and the ground particles are taken.
[0052] Waste ceramics 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 %, 0.5% of non-ionic dispersant, 0.5% of silicone defoamer, 0.2% of isothiazolone anticorrosion and antifungal agent, 0.5% of polyurethane thickener, 0.1% of organic amine pH regulator, and the balance of water.
[0053] It is mainly made by the following methods:
[0054] Weigh the above-measured modified hydroxyethyl cellulose, non-ionic dispersant, isothiazolone anti-corrosion and anti-mold agent, propylene glycol and 3 / 4 of the silicone defoamer, add 4 / 5 of the water, at a spe...
