Embodiment 1

[0033] Embodiment 1 prepares multifunctional coating additive V

[0034] The camphor added in the multifunctional coating additive V is synthetic camphor, the solvent is ethylene glycol monobutyl ether, and the catalyst is dibutyltin dilaurate. The weight ratio of each component is:

[0035] Synthetic Camphor 40

[0036] Ethylene glycol monobutyl ether 59

[0037] Dibutyltin dilaurate 1 25

[0038] 200g of synthetic camphor and 5g of dibutyltin dilaurate were added to 295g of ethylene glycol monobutyl ether, and stirred to obtain multifunctional coating additive V. The appearance of Multifunctional Coating Auxiliary V is a slightly turbid light yellow solution.

Embodiment 2

[0039] Embodiment 2 prepares multifunctional coating additive W

[0040] The camphor added in the multifunctional coating additive W is natural camphor, the solvent is ethylene glycol monobutyl ether, and the catalyst is cobalt naphthenate. The weight ratio of each component is:

[0041] Natural Camphor 60

[0042] Ethylene glycol monobutyl ether 35

[0043] Cobalt naphthenate 5

[0044] 300g of natural camphor and 25g of dibutyltin dilaurate were added to 175g of ethylene glycol monobutyl ether respectively, and stirred to obtain multifunctional coating additive W. The appearance of the multifunctional coating additive W is a dark brown solution.

[0045] In some other embodiments, the weight ratio of camphor, solvent and catalyst can also be 50:47:3 or 45:52:3.

Embodiment 3

[0046] Embodiment 3 prepares multifunctional water-phase paint X

[0047] The components and their weights contained in Multifunctional Water Phase Coating X are:

[0048]

[0049] Among them, the coconut oil resin emulsion is A432-70, the leveling agent is BYK-333, the antifungal agent is PreventolCMK, the dispersant is EFKA-4010, the defoamer is EFKA-2020, and the anti-settling agent is BYK-410. The additive is butyl acetate. The filler is titanium dioxide and talcum powder, and the weight ratio of the two is 15:35.

[0050] Preparation:

[0051] 1) Accurately weigh each component;

[0052] 2) Add the coconut oil resin emulsion and water into the mixing tank;

[0053] 3) Start stirring, slowly add the leveling agent under the stirring condition of 400-500rpm, stir evenly, then add the dispersant, and stir for 5-10min;

[0054] 4) Add defoamer and filler in sequence, stir evenly, and disperse the mixture to a fineness below 30 microns;

[0055] 5) Increase the stirr...

Abstract

The invention discloses a multifunctional coating additive which shows a remarkable effect on removing formaldehyde from an indoor environment. The multifunctional coating additive comprises camphor, a solvent and a catalyst, wherein the camphor is composed of at least one of natural camphor or synthesized camphor. The invention also discloses an oil coating and a multifunctional water-based coating which both contain the multifunctional coating additive, and a preparation method of the multifunctional water-based coating. The multifunctional coating additive, provided by the invention, is a coating additive with outstanding formaldehyde removal effect and can meet the demand on indoor environment. The coating with such multifunctional coating additive has the functions of resisting mould, guarding against damp, protecting against insects, and proofing moth; the inspection result of authorities shows that the coating additive can effectively remove formaldehyde from the indoor environment.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a multifunctional coating additive, a multifunctional coating and a preparation method for the multifunctional coating. Background technique [0002] At present, in house decoration, due to the formaldehyde, benzene series, TVOC and other harmful substances brought by various decoration materials, the home decoration pollution and the harmful substances in the indoor air exceed the standard. Has seriously interfered with people's daily life. The long-term absorption of this formaldehyde-containing gas by the human body can cause various diseases, and even endanger human life in serious cases. Therefore, it is necessary to control the indoor air pollution of the renovated rooms and the newly purchased furniture, and eliminate the pollution of harmful gases brought by the new furniture. In order to ensure that the content of indoor harmful gases is within the range stipulated by the state...
