Embodiment 1

[0025] The raw materials of the paint breaker are: melamine 20kg, formaldehyde solution (concentration is 35%) 50kg, ammonium chloride 5kg, hydrochloric acid (concentration is 30%) 20kg, water 850kg.

[0026] The preparation method of above-mentioned raw material, comprises the following steps: (1) take each raw material according to the parts by weight of above-mentioned raw material, set aside;

[0027] (2) Add raw material water in the reaction kettle to heat up and stir, heat up to 35°C, add melamine and continue stirring for 30 minutes; heat up to 40°C, add formaldehyde solution and ammonium chloride, and keep the temperature at 40°C for 120 minutes until the solution is transparent, stop heating And add hydrochloric acid to react for 300min. After the reaction is completed, a paint breaker with a pH of 1.5-3 is obtained, and the temperature is lowered to 20°C for storage.

Embodiment 2

[0029] The raw materials of the paint breaker are: melamine 100kg, formaldehyde solution (concentration is 38%) 150kg, ammonium chloride 15kg, hydrochloric acid (concentration is 36%) 80kg, water 665kg.

[0030] The preparation method of above-mentioned raw material, comprises the following steps: (1) take each raw material according to the parts by weight of above-mentioned raw material, set aside;

[0031] (3) Add raw material water in the reaction kettle to heat up and stir, heat up to 55°C, add melamine and continue stirring for 30 minutes; heat up to 80°C, add formaldehyde solution and ammonium chloride, and keep the temperature at 80°C for 40 minutes until the solution is transparent, stop heating And add hydrochloric acid to react for 100 minutes. After the reaction is completed, a paint breaker with a pH of 1.5-2 is obtained, and the temperature is lowered to 20°C for storage.

Embodiment 3

[0033] The raw materials of the paint breaker are: melamine 50kg, formaldehyde solution (concentration is 38%) 75kg, ammonium chloride 8kg, hydrochloric acid (concentration is 36%) 45kg, water 822kg.

[0034] The preparation method of above-mentioned raw material, comprises the following steps: (1) takes each raw material according to the parts by weight of above-mentioned raw material;

[0035] (2) Add raw material water in the reaction kettle to heat up and stir, heat up to 40°C, add melamine and continue stirring for 30 minutes; heat up to 60°C, add formaldehyde solution and ammonium chloride, and keep the temperature at 60°C for 60 minutes until the solution is transparent, stop heating And add hydrochloric acid to react for 180min. After the reaction is completed, a paint breaker with a pH of 1.5-2 is obtained, and the temperature is lowered to 20°C for storage.

Abstract

The invention discloses a paint viscosity breaker. The paint viscosity breaker comprises, by weight, 20-100 parts of melamine, 50-150 parts of a formaldehyde solution, 5-15 parts of ammonium chloride,20-80 parts of hydrochloric acid and 665-905 parts of water. A preparation method of the paint viscosity breaker comprises the following steps: (1) weighing the raw materials in parts by weight for later use; (2) adding the raw material water into a reaction kettle, heating and stirring the water, adding the melamine and performing continuous stirring when the temperature is raised to a first stage, adding the formaldehyde solution and ammonium chloride when the temperature is raised to a second stage, keeping the temperature constant until transparency, stopping heating, adding the hydrochloric acid, obtaining the paint viscosity breaker after a reaction is finished, and cooling and storing the product. The prepared viscosity breaker is used to achieve good paint slag debonding effect, convenient fishing and storage of the paint slag, no accumulation of the paint slag in a spraying room, and continuous production.

Description

technical field [0001] The invention relates to the technical field of environmental pollution control, in particular to a paint breaker and a preparation method thereof. Background technique [0002] In the automobile, home appliance, furniture industries, and some daily necessities manufacturing industries, there is a painting process. A large amount of paint mist will be generated in the spraying process, and 20% to 60% of the paint cannot be effectively used, which is called overspray paint; overspray paint mist that is not attached to the surface of the object to be treated not only forms serious pollution, but also causes damage to the coating material. waste. In the spray booth, the circulating water paint separation system is generally used. In order to maintain the long-term safe operation of the circulating water, the overspray paint must be separated from the circulating water. This requires that the paint mist be fully debonded to facilitate separation; the det...
