Description
Technical Field
The invention belongs to the technical field of textile auxiliary agents, and particularly relates to a low-foam high-concentration scouring agent and a preparation method thereof.
Background
Before dyeing and finishing or other treatments, the fabric is usually subjected to a pretreatment process, which is to remove impurities, size, fluff and the like on the fabric, so as to improve the subsequent finishing performance of the fabric. The fabric scouring is an important link in the textile pretreatment process. Through refining, the impurities such as pectin, cotton wax, cottonseed hulls, grease, slurry which is not completely removed in the desizing process and the like on the fabric can be removed, so that the subsequent treatment of the fabric is facilitated. The scouring process is a complex process of treating textiles with alkali and scouring aids involving the action of penetration, emulsification, washing, dispersion, wetting, etc. Surfactants and their complexes have been widely used as the main components of scouring agents.
However, most surfactants and their formulations generate more foam during practical use. Excessive foaming may cause flash, affect practical operation, etc., and thus the foaming of the scouring agent during use must be effectively controlled.
At present, a common method for controlling foam is to add a silicon-containing defoaming agent, and excessive use of the silicon-containing defoaming agent can cause oil stains on fabrics due to demulsification and even influence the appearance, stability and the like of products. In addition, compared with the commercial scouring agent, most of the scouring agent is a product with the content of less than 50 percent, and the transportation cost is increased to a certain extent.
Therefore, under the condition of ensuring that the scouring agent has excellent emulsification, wetting, washing and dispersion effects, the use of a silicon-containing defoaming agent is reduced, a new defoaming system is developed, the effective content of a product is improved, and the low-foam high-concentration scouring agent prepared has certain market prospect.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides a high-low foam concentration scouring agent which has high concentration, low foam, transparent product appearance, stable storage, low transportation cost and small addition amount in the use process; the fabric treated by the scouring agent has good whiteness, capillary effect, strength and no oil spots; meanwhile, the invention provides a preparation method.
The low-foam high-concentration scouring agent comprises the following components in percentage by mass:
the defoaming agent is a compound of polypropylene glycol and amide defoaming agents, and the solubilizer is cumenesulfonate.
Preferably, the polypropylene glycol has a molecular weight of one of 2000, 4000 or 6000.
Preferably, the amide antifoaming agent is N-butyl-2-ethylhexanoamide or N- (2-ethylhexyl) isononamide.
Preferably, the mass ratio of the polypropylene glycol to the amide defoaming agent is 1-3: 0.5-1.5.
Preferably, the fatty alcohol carbon atoms of the fatty alcohol polyoxyethylene ether 3EO, the fatty alcohol polyoxyethylene ether 5EO and the fatty alcohol polyoxyethylene ether 7EO are 10-14.
Preferably, the isomeric tridecanol polyoxyethylene ether has an ethylene oxide number of from 15 to 20.
Preferably, the fatty alcohol polyoxyalkyl ether is C12-14Alcohol 5EO-4PO polyoxyalkyl ether, C12-15Alcohol 8EO-3PO polyoxyalkyl ether or sorbitol 3EO-5PO polyoxyalkyl ether.
Preferably, the solubilizer is one of sodium cumene sulfonate, potassium cumene sulfonate or ammonium cumene sulfonate.
Preferably, the organic solvent is diethylene glycol monobutyl ether or 2-methyl-2, 4-pentanediol.
The preparation method of the low-foam high-concentration scouring agent comprises the following steps: sequentially adding fatty alcohol-polyoxyethylene ether 3EO, fatty alcohol-polyoxyethylene ether 5EO, fatty alcohol-polyoxyethylene ether 7EO, isomeric tridecanol polyoxyethylene ether, fatty alcohol-polyoxy alkyl ether and an organic solvent into a reactor according to a proportion, heating to 40-50 ℃, uniformly stirring, and stopping heating; adding polypropylene glycol and amide defoaming agent in sequence, and stirring uniformly; and then adding water and a solubilizer, uniformly stirring, filtering and discharging.
The invention adopts a compound defoaming system to realize the low-foam characteristic of the product, both defoamers have certain defoaming and foam inhibiting functions, but the polypropylene glycol defoamer is more prone to inhibiting foam, namely, the polypropylene glycol defoamer can inhibit foam generation in the using process. While amide defoamers tend to be more defoaming, i.e., capable of breaking foam quickly after foam generation. The two are matched for use, and the foam inhibiting and defoaming capability is provided to the maximum extent.
According to the invention, surfactants with different carbon chain lengths and different EO numbers are selected for compounding, and in order to meet the low-foam characteristic of the product, the surfactants with EO numbers of 3 and 5 are selected, and the proportion of the EO numbers to the surfactants is larger (the lower the EO number is, the less foam is generated in the surfactant with the same carbon chain number). In addition, the added fatty alcohol polyoxyalkyl ether, namely EO-PO block polyoxyalkyl ether, is a low-foaming surfactant due to PO contained in the molecule, and further realizes the low-foaming characteristic of the product. Meanwhile, as the prepared high-concentration scouring agent, in order to ensure that the added surfactant can be fully mixed and dissolved with water and the product can be diluted, a solubilizer is added into the system besides a conventional solvent.
Compared with the prior art, the invention has the following beneficial effects:
(1) according to the invention, a new defoaming system, namely a polypropylene glycol defoaming agent is selected to be compounded with an amide defoaming agent, so that the traditional organic silicon defoaming agent is replaced, and a low-foaming surfactant (fatty alcohol polyoxyalkyl ether, namely EO-PO block polyoxyalkyl ether) is matched, so that the prepared product is transparent in appearance, good in storage stability, less in foam, fast in defoaming, capable of avoiding the overflow phenomenon in the refining treatment of the fabric, and the treated fabric has good whiteness, capillary effect, strength and no oil spots;
(2) the solubilizer is added, so that customers can use or sell the product according to the conditions of the customers, and the product after dilution is transparent in appearance and free of turbidity;
(3) the product prepared by the invention has higher concentration, saves the transportation cost and improves the working efficiency.
