Embodiment 1

[0020] The mass percent of each component of sodium percarbonate anti-caking agent is:

[0021] 70% Dispersant: 45% maleic acid-acrylic acid copolymer, 25% sodium polyacrylate;

[0022] 25% penetrant: 15% sodium alkylbenzene sulfonate, 10% fatty alcohol polyoxyethylene ether;

[0023] 5% Hydrophobic agent: sodium stearate.

[0024] After preparing each component according to the above ratio, mix them evenly to obtain the anti-caking agent. Add the anti-caking agent according to 0.5% of the total mass of sodium percarbonate. The specific addition method is: dissolve the above-mentioned anti-caking agent in water to make a solution, and apply the anti-caking agent solution evenly on the overcoating surface through a fluidized bed spraying device. The surface of the sodium carbonate particles is used to obtain anti-caking sodium percarbonate. In addition, after pulverizing the anti-caking agent of the above proportion to make a powder, it is uniformly mixed with the sodium per...

Embodiment 2

[0027] The mass percent of each component of sodium percarbonate anti-caking agent is:

[0028] 60% Dispersant: maleic acid-acrylic acid copolymer;

[0029] 35% penetrant: 15% sodium alkylbenzene sulfonate, 10% sodium secondary alkyl sulfonate, 10% fatty alcohol polyoxyethylene ether;

[0030] 5% Hydrophobic agent: sodium stearate.

[0031] After preparing each component according to the above ratio, mix them evenly to obtain the anti-caking agent. Add anti-caking agent by 0.05% of the total mass of sodium percarbonate, and other operations are the same as example 1.

[0032] Gained anti-caking sodium percarbonate is packaged in a ton bag, and the product has no caking after being stored in a compressed bag for 6 months.

Embodiment 3

[0034] The mass percent of each component of sodium percarbonate anti-caking agent is:

[0035] 60% Dispersant: maleic acid-acrylic acid copolymer;

[0036] 35% penetrant: sodium secondary alkyl sulfonate;

[0037] 5% Hydrophobic agent: sodium stearate.

[0038] After preparing each component according to the above ratio, mix them evenly to obtain the anti-caking agent. Add anti-caking agent by 0.2% of the total mass of sodium percarbonate, and other operations are the same as example 1. Gained anti-caking sodium percarbonate is packaged in a ton bag, and the product has no caking after being stored in a compressed bag for 6 months.

Abstract

The invention relates to a sodium percarbonate anti-caking agent composite, which is characterized by being composed of a dispersing agent, a penetrating agent and a water repellent. Mass percent of the dispersing agent, the penetrating agent and the water repellent is 45-70: 20-40:5-15. The invention further provides application of the composite in preparation of anti-caking sodium percarbonate. The sodium percarbonate anti-caking agent composite is small in dosage, low in production cost and good in anti-caking effect. Addition of an anti-caking agent does not influence stability and various operating requirements of sodium percarbonate, and the sodium percarbonate anti-caking agent composite has assistant washing functions, and is nonhazardous to environment and suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of inorganic salts, in particular to an anti-caking agent composition for sodium percarbonate and its application technology. Background technique [0002] Sodium percarbonate, also known as sodium peroxycarbonate, is an addition complex of sodium carbonate and hydrogen peroxide, and is a white loose granular solid with good fluidity. As a new type of high-efficiency detergent bleach, it is odorless, non-toxic and non-polluting. Because the active oxygen generated by decomposition in water has a bleaching effect, sodium percarbonate shows a strong decontamination ability. Therefore, compared with traditional phosphorus and boron detergent builders, it not only has strong detergency, but also does not damage the ecological environment. , has become one of the main detergent builders widely used in the world. [0003] At present, the production methods of sodium percarbonate mainly include dry method and wet...
