Problems solved by technology

However, organic acid phosphates, especially pure alkyl (C12, C14, C16, C18) acid phosphates are in a solid state at temperatures below 35°C; taking this product at 17KG as an example, it needs to be It can be used after being stored in a constant temperature storage room at 80°C for 24 hours; but because the production, storage and use of water-based coatings are generally controlled within the range of 5-35°C during production, storage, and use, the raw material at 80°C will destroy the water-based emulsion after being added directly. stability, leading to problems such as resin precipitation; this not only increases the difficulty of use but also increases energy consumption
[0003] The existing solution is to dissolve this product in xylene to prepare a xylene solution containing 50% of this product; the prepared mixed solution is still in a solid state after being stored at a temperature below 15°C; there is still addition of additives when used in winter Potentially inconvenient; so this mixed solution needs to be stored in a constant temperature storage room when used in winter; in addition, with the increasing environmental protection requirements, using xylene to dissolve this phosphate may not meet environmental protection requirements in the future

preparation example Construction

[0046] Another specific embodiment of the present invention provides the preparation method of the liquid acid phosphate composition as described above, comprising the steps of:

[0047] Place the organic acid phosphate at a high temperature and constant temperature until it is in a liquid state;

[0048] Mix propylene glycol butyl ether and dimethylethanolamine evenly in proportion to obtain a mixed solution;

[0049] The organic acid phosphate in liquid state is mixed with the above mixed solution in proportion, and dispersed uniformly to obtain the liquid acid phosphate composition.

[0050] In a preferred example, the temperature of the above-mentioned high temperature and constant temperature storage is about 80°C.

[0051] In yet another preferred example, the mixing of the organic acid phosphate in liquid state and the mixed solution is carried out at normal temperature or low temperature. Preferably 5-35°C.

[0052] In yet another specific embodiment, a water-based ...

Embodiment 1

[0058] A liquid acid phosphate composition is composed of: 75wt% propylene glycol butyl ether, 5wt% dimethylethanolamine and 20wt% dodecyl phosphate.

[0059] The preparation method of above-mentioned liquid acidic phosphate composition, comprises the steps:

[0060] Store the dodecyl phosphate in a constant temperature storage room at 80°C until it is in a liquid state; wherein, the molecular formula of dodecyl phosphate is: C 12 h 27 o 4 P, the structural formula is as follows:

[0061]

[0062] Mix the propylene glycol butyl ether and dimethylethanolamine, stir and disperse evenly;

[0063] Mix the liquid dodecyl phosphate with the mixture of propylene glycol butyl ether and dimethylethanolamine at 10° C., stir and disperse evenly to obtain the liquid acid phosphate composition. The liquid acid phosphate composition is in a stable liquid state at 10°C, and it is still in a stable liquid state for more than 30 days at low temperature and normal temperature, and its fo...

Embodiment 2

[0065] A liquid acid phosphate composition comprising: 73 wt% propylene glycol butyl ether, 5 wt% dimethylethanolamine and 22 wt% myristyl phosphate.

[0066] The preparation method of above-mentioned liquid acidic phosphate composition, comprises the steps:

[0067] Store myristyl phosphate in a constant temperature storage room at 80°C until it is in a liquid state. Among them, the structure of myristyl phosphate is similar to that of dodecyl phosphate, and the chemical formula is: C 14 h 31 o 4 P);

[0068] Mix propylene glycol butyl ether and dimethylethanolamine, stir and disperse evenly;

Abstract

The invention discloses a liquid acid phosphate composition, which comprises organic acid phosphate, propylene glycol butyl ether and dimethylethanolamine. The composition is liquid at high temperature, normal temperature and low temperature (can be as low as 5°C), and can be well used in water-based paints. While it can better improve the recoating adhesion of water-based paints, it does not Affect other properties of the water-based coating. The invention also discloses the preparation method and application of the composition.

Description

technical field [0001] The invention relates to the field of water-based coatings. More specifically, it relates to a liquid acid phosphate composition and its preparation method and application. Background technique [0002] Acid phosphates can be used as additives in coatings. However, organic acid phosphates, especially pure alkyl (C12, C14, C16, C18) acid phosphates are in a solid state at temperatures below 35°C; taking this product at 17KG as an example, it needs to be It can be used after being stored in a constant temperature storage room at 80°C for 24 hours; but because the production, storage and use of water-based coatings are generally controlled within the range of 5-35°C during production, storage, and use, the raw material at 80°C will destroy the water-based emulsion after being added directly. The stability of the resin will lead to problems such as resin precipitation; this will not only increase the difficulty of use but also increase energy consumption...
