Problems solved by technology

[0010] In addition, AEPD TM Although VOX1000 has the functions of adjusting pH value, assisting dispersion, assisting freeze-thaw stability, etc., it cannot completely replace the commonly used antifreeze to maintain the freeze-thaw stability of the system alone, and it still needs to add propylene glycol, etc.
AEPD TM When VOX1000 adjusts the pH value, its addition amount is usually not higher than 0.5% (wt), which cannot completely replace propylene glycol or ethylene glycol as antifreeze to ensure the freeze-thaw stability of the coating; in addition, AEPD TM VOX1000 itself has a pungent odor and a yellowish color (not higher than Gardner's 2nd grade), which has obvious adverse effects on the production of low-odor or clean-odor paints and the preparation and production of white or light-colored paints

Embodiment 1

[0205] Process: At room temperature (usually 25°C), under stirring at an appropriate level (usually 200-1500 rpm), add deionized water, and then add tromethamine and bis(2-hydroxyethyl)amino (tri hydroxymethyl)methane, stirring continuously until completely dissolved, then adding AEPD TM Mix VOX1000 and trihydroxytriethylamine evenly to obtain the water-based additive composition of the present invention.

Embodiment 2

[0207] Process: under the condition of 30°C, under stirring at an appropriate level (usually 200-1500 rpm), add deionized water, then add 1,3-bis((trimethylol)methylamino)propane, and keep stirring Until it is completely dissolved, then add serinol, keep stirring until it is completely dissolved, then add threoninol, keep stirring until it is completely dissolved, then add aminobutanediol, keep stirring until it is completely dissolved, then add trihydroxytriethylamine, mix Evenly, the water-based additive composition of the present invention is obtained.

Embodiment 3

[0209] Process: under the condition of 35°C, under stirring at an appropriate level (usually 200-1500 rpm), add deionized water, then add 1,3-bis((trimethylol)methylamino)propane, and keep stirring Until it is completely dissolved, then add aminobutanediol, continue to stir until it is completely dissolved, then add trihydroxytriethylamine, and mix evenly to obtain the water-based additive composition of the present invention.

Abstract

The invention provides a water-based additive composite. The water-based additive composite comprises the following components of: primary amine at least containing an alpha-site hydroxyl group, and secondary amine or tertiary amine at least containing a hydroxyl group. The composite has functions for being used for preparing water-based coating, water-based ink, water-based bonding agents and water-based sealants, volatilized formaldehyde removers, freezing-thawing stabilizers (anti-freezing agent), metal container tank internal-corrosion and flash-rust inhibitors, construction time limit delayers, adhesive force promoters, pH regulators, auxiliary dispersing agents, VOC (Volatile Organic Compound) content reducers and the like. A preparation method of the water-based additive composite provided by the invention is as follows: the components of the composite are mixed and stirred under the condition from the ambient temperature to the proper heating temperature according to an arbitrary sequence, and are dispersed till that homogeneous dispersoids are obtained.

Description

technical field [0001] The invention relates to a water-based additive composition, which is used for water-based latex paint, water-based wood paint, water-based plastic paint, water-based metal paint, water-based leather finishing agent, water-based fabric coating, water-based ink, water-based adhesive, water-based sealant and Other water-based paints can also be used alone and belong to the field of fine chemicals. Background technique [0002] Coatings are divided into solvent-based coatings and water-based coatings according to the dispersion medium used. Solvent-based coatings have been gradually replaced by water-based coatings because of their serious air pollution and serious impact on the health of people in the environment; as the name suggests, water-based coatings use water as a solvent or dispersion medium, and their safety is significantly improved compared to solvent-based coatings. At present, water-based coatings have been regarded as environmentally frien...
