Abstract
The application relates to the field of cleaning agents, and particularly provides a low-foam rinsing agent for tableware; the components of the rinsing agent comprise polyether defoamer, organosilicon defoamer and water. The polyether defoamer accounts for 3 to 40 percent of the total mass of the rinse agent, and the organosilicon defoamer accounts for 0.01 to 3 percent of the total mass of the rinse agent. The foam inhibition and defoaming effects of the rinse agent can be effectively improved by compounding the polyether defoamer and the organosilicon defoamer and adding a small amount of the rinse agent; the types and the dosage of the two are further optimized, and the defoaming speed and the system stability can be improved; the rinse agent can be used in the cleaning process of a dish washer, improves the drying speed of tableware and avoids the generation of speckles after drying.
Description
Technical Field
The invention relates to the technical field of cleaning agents, in particular to a low-foam rinsing agent for tableware and a use method thereof, wherein C11D1/00 is used.
Background
The tableware in the catering industry is generally cleaned by adopting a mechanized dish washing machine, a detergent is added before the tableware enters the dish washing machine for presoaking, and the tableware enters the dish washing machine for washing steps of presoaking, main washing, rinsing and drying in sequence after water is washed. However, the active ingredients of the traditional detergent are mainly anionic surfactants such as sodium dodecyl benzene sulfonate, fatty alcohol polyoxyethylene ether sodium sulfate and the like, and the washing products prepared by the surfactants have the problems of large foam amount, difficult foam removal and difficult rinsing, so that the detergent on the tableware is still difficult to effectively remove by simple water after soaking, the cleaning effect in a dish washer is affected, and residual spot marks are caused after the tableware is dried; this is mainly because: residual detergent is easily brought into the dish washer, and the foam amount in the dish washer is further increased due to the strong mechanical force action of the dish washer, the chemical reaction of residual grease on the dishes, and the like, so that the strength of washing the dishes by high-pressure water flow in the dish washer is reduced, and the decontamination effect is reduced.
The washing system of the dish washer is divided into main washing and rinsing; the cleaning agent used in the main washing mainly comprises chelating agent, dispersing agent and alkali, and a small amount of low-foam surfactant is added; the main functions of the rinse agent used in the rinse stage are to accelerate drying, improve the appearance of the dishes by reducing water stains, and to inhibit and eliminate foam in the main tub. The rinse agent reduces the surface tension of rinse water to form a layer of uniform thin water film on the surface of the tableware, and then the heat energy accumulated in the main washing and rinsing stages is used for achieving the effect of quick drying, and at the same time, the chelating agent and the dispersing agent in the rinse agent uniformly spread calcium and magnesium ions in the water on the surface of the tableware, so that obvious spots and stripes cannot flow down.
The general composition of the rinsing agent commonly used in the market at present comprises a surfactant, a drier and various auxiliary agents, wherein the surfactant mainly comprises a wetting agent, a defoaming agent and the like; however, the existing rinsing agent still has the defects of weak foam breaking effect, high consumption, residual speckles on the surface of tableware, influence on the taste of food, entering the body of a consumer along with the food and the like. Chinese patent CN109234071B discloses a foam control agent and a preparation method thereof, wherein a wrapping agent and a polyether carrier are introduced, and a specific mixing method and a post-drying method are matched, so that the surface of a foam control active substance can wrap a layer of hydrophobic substance, the aim of slow release can be achieved in the washing process, the problem of 'silicon spots' caused by instant release of the active substance is solved, and the foam control agent has good foam inhibition and defoaming capability, but the addition amount of the foam control agent is higher. Chinese patent CN115746974B discloses an organosilicon defoaming composition, a preparation method thereof and a defoaming agent, wherein the organosilicon defoaming composition comprises linear hydrogen-containing polysiloxane, space structure silicon hydrogen vinyl polysiloxane, alpha-olefin, methyl silicone resin and silicon dioxide; the viscosity of the composition is reduced through component compounding, so that the formation of silicon spots is avoided, and the quantity of foam is controlled for a long time; but its defoaming speed is still slow.
Therefore, the research on the rinse agent not only can inhibit and eliminate foam in the main washing tank, but also can achieve the effects of quick drying, reducing water stains and improving the appearance of tableware, and has very important significance.

In the polyether defoamer, a polyoxypropylene segment, namely a PO segment, can improve the hydrophobic property of the copolymer, a polyoxyethylene segment, namely an EO segment, can improve the water solubility of the copolymer, and when the PO segment is increased, the cloud point of the system can be reduced, the foam inhibition capability is improved, but the polyether defoamer is not easy to emulsify due to excessive PO quantity, and the system stability is poor; however, when the EO amount is too large, the cloud point is increased, the lipophilicity is obviously reduced, and the foam inhibition and defoaming effects are reduced. The application uses the fatty alcohol polyoxyethylene ether polyoxypropylene ether block copolymer with special cloud point and the C12-15 fatty alcohol polyether to compound, and utilizes the different carbon chain lengths and cloud points of the block copolymer and the C12-15 fatty alcohol polyether to endow the system with optimal permeability, foam inhibition effect and defoaming effect.

Further, the silicone defoamer further comprises TEGO 6801, and the mass ratio of SagTex PhD to TEGO 6801 is 0.5-2:1, preferably 1:1.
The organic silicon defoamer and the polyether defoamer can effectively improve the defoaming and foam inhibiting effects of the rinse agent, and the technical effects are better when the polyether modified organic silicon is further compounded for use. Because the organic silicon is grafted or block-modified by polyether, the combined action of the two components can be exerted, the hydrophilic polyether chain segment endows the organic silicon with self-emulsifying property, the hydrophobic polysiloxane chain segment can reduce the surface tension so as to reduce the affinity and the solubility of the polysiloxane in an oil system, increase the water solubility of the polysiloxane, improve the defoaming and foam inhibition properties and endow the organic silicon with excellent heat resistance and acid-base resistance. On the basis, the defoaming speed can be further improved when TEGO 6801 and SagTex PHD are compounded in the system; TEGO 6801 has a viscosity of 600-900cps,SagTex PHD at 25 ℃ and 1500-2500sps at 25 ℃, the viscosity is an indirect parameter for reacting the polymerization degree and the molecular weight of the TEGO 6801 and the TEGO 6801, and the TEGO can be compounded at the viscosity to generate optimal system viscosity, hydrophilic performance and permeability, so that the foam breaking speed of the system is improved by effectively reducing the surface tension of the system. When the amount of the two is too large, the emulsification and dispersion effects in the system become poor, the lipophilicity becomes large, and the instability of the rinse agent is caused

In addition, when sodium polyacrylate with a proper molecular weight is selected, the stabilizing effect of the system is more excellent. However, the dosage of the sodium polyacrylate and the solubilizer needs to be strictly controlled, and when the dosage of the sodium polyacrylate is too large, firstly, the system is unstable and layering occurs, and the dosage of the sodium xylene sulfonate solubilizer needs to be increased, and secondly, the phenomenon of obvious trace after tableware cleaning is caused.
