Detailed Description
The first aspect of the invention provides a novel alkaline hard floor cleaning agent, which comprises the following raw materials, by weight, 1-5 parts of sodium alkyl benzene sulfonate, 1-5 parts of alkyl benzene sulfonic acid, 0.5-5 parts of liquid caustic soda, 0.5-2 parts of emulsifier, 0.1-3 parts of disodium ethylene diamine tetraacetate, 0.1-2 parts of dispersant, 0.1-0.5 part of preservative, 0.05-0.2 part of essence and 90-95 parts of water.
Preferably, the novel alkaline hard floor cleaning agent comprises, by weight, 2-4 parts of sodium alkyl benzene sulfonate, 1-3 parts of alkyl benzene sulfonic acid, 1.5-3 parts of liquid caustic soda, 1-1.5 parts of emulsifier, 0.5-1 part of disodium ethylene diamine tetraacetate, 0.8-1.2 parts of dispersant, 0.2-0.3 part of preservative, 0.08-0.12 part of essence and 90-95 parts of water.
Preferably, the raw materials of the novel alkaline hard floor cleaning agent also comprise modified acrylic acid polymer.
The sodium alkyl benzene sulfonate is sodium dodecyl benzene sulfonate.
The sodium dodecyl benzene sulfonate is an anionic surfactant, and the prepared cleaning agent has better cleaning effect on hard ground due to the mutual synergistic action of the sodium dodecyl benzene sulfonate, the emulsifier and the modified acrylic emulsion in the system.
Preferably, the sodium dodecylbenzene sulfonate is linear sodium dodecylbenzene sulfonate.
The degradability of the linear sodium dodecylbenzene sulfonate is better than that of the branched sodium dodecylbenzene sulfonate, and the synergistic effect of the linear sodium dodecylbenzene sulfonate and the modified acrylic emulsion is better in the invention, probably because the linear sodium dodecylbenzene sulfonate has better wettability than that of the branched chain, and can be better interpenetrated and synergistic with hydroxylated multi-walled carbon nanotubes on the surface of the modified acrylic emulsion.
The alkylbenzene sulfonic acid is dodecylbenzene sulfonic acid.
Dodecylbenzene sulfonic acid is generally used as a raw material for producing sodium dodecylbenzene sulfonate, but in the system of the invention, the applicant unexpectedly finds that the addition of the dodecylbenzene sulfonic acid enables the cleaning agent to have better cleaning effect on hard floors, probably because the system is an alkaline system, and the addition of the dodecylbenzene sulfonic acid can balance the pH value in the system and cannot damage the modified acrylic polymer to form a temporary glossy water film on the hard floors.
The liquid caustic soda is sodium hydroxide liquid with the mass solubility of 30%.
In the system of the present invention, liquid caustic soda can be used for removing oil stains on hard ground by the synergistic effect of saponification, emulsification and soaking and wetting with other raw materials in the system.
The emulsifier is at least one selected from AEO-3, AEO-4, AEO-5, AEO-7, AEO-9, AEO-15, AEO-20 and AEO-23.
In the system, the synergistic effect of the AEO series emulsifier and the dispersant is utilized, so that slight oil stain can be quickly emulsified and dissolved, and the cleaning efficiency of the product is improved.
Preferably, the emulsifier is AEO-7 and/or AEO-9.
AEO-7 and AEO-9 are easily soluble in water, and the compatibility of AEO-7 and AEO-9 in the system is better, so that the synergistic effect of AEO-7 or AEO-9, the modified acrylic acid polymer and the sodium dodecyl benzene sulfonate is possibly better, and the cleaning effect of the prepared cleaning agent is better.
More preferably, the emulsifier is a mixture of AEO-7 and AEO-9, and the weight ratio of AEO-7 to AEO-9 is 2: 3.
The applicant finds that the emulsifier is a mixture of AEO-7 and AEO-9, and the cleaning effect of the prepared cleaning agent is better, and the stability is better. Probably because in the system, the synergistic effect of AEO-7 and AEO-9 makes the cleaning effect of the cleaning agent on the ground better.
In the invention, the disodium ethylene diamine tetraacetate not only can make the performance of the cleaning agent more stable, but also can protect a 'glossy water film' formed on the hard floor after the hard floor is cleaned.
The dispersant is an alcohol ether dispersant.
In the system, the applicant finds that when the alcohol ether dispersant is used, the cleaning capacity of the cleaning agent on the oil stain on the hard floor is better, probably because the ether bonds are contained in AEO-7 and AEO-9, the alcohol ether dispersant and the ether bonds in AEO-7 and AEO-9 are mutually intertwined, so that the oil stain on the hard floor can be well emulsified and dissolved in the cleaning agent, and meanwhile, the alcohol ether dispersant contains alcoholic hydroxyl groups, so that the compatibility with the system is better, and the cleaning effect of the cleaning agent is better.
Preferably, the alcohol ether dispersant is at least one selected from the group consisting of triethylene glycol ethyl ether, triethylene glycol methyl ether, diethylene glycol methyl ether, propylene glycol propyl ether, ethylene glycol phenyl ether, propylene glycol phenyl ether, dipropylene glycol dimethyl ether, dipropylene glycol propyl ether, diethylene glycol butyl ether, dipropylene glycol butyl ether, and tripropylene glycol butyl ether.
More preferably, the alcohol ether dispersant is diethylene glycol butyl ether and/or dipropylene glycol butyl ether.
Applicants have discovered that when the alcohol ether dispersant is diethylene glycol butyl ether and/or dipropylene glycol butyl ether, the cleaning agent works better, possibly because the butyl ether segments in diethylene glycol butyl ether and dipropylene glycol butyl ether have longer segments than methyl ether and ethyl ether, which provide better entanglement with the ether linkages in AEO-7 and AEO-9, while the branches in diethylene glycol butyl ether and dipropylene glycol butyl ether, which are less branched than tripropylene glycol butyl ether, provide better compatibility with other materials in bathing systems having lower viscosity.
Most preferably, the alcohol ether dispersant is a mixture of diethylene glycol butyl ether and dipropylene glycol butyl ether, and the weight ratio of the ethylene glycol butyl ether to the dipropylene glycol butyl ether is 1: 1.
the preservatives are not limited and suitable preservatives for use in cleaning agents are suitable for use in the present system.
The preservative may be sodium benzoate, triclosan, cason, propylparaben, sodium hexametaphosphate, methylisothiazolinone, or nitrite.
In this embodiment, the preservative is cason.
The essence commonly used in the art is not particularly limited as long as it is commonly used in the art, and may be added according to the odor required by the cleaning agent, for example, the essence includes, but is not limited to, lemon essence, sweet orange essence, osmanthus essence, jasmine essence, rose essence, and the like.
In this embodiment, the essence is lemon essence.
The water is soft water.
In the system of the invention, the cleaning effect of the cleaning agent prepared by using soft water is better.
The modified acrylic polymer is prepared according to the following preparation method:
(1) adding sodium dodecyl sulfate, ammonium persulfate and AEO-9 into a reaction kettle, then adding deionized water, and stirring at the rotating speed of 1000r/min of 800-: 3: 2, the ratio of the volume (mL) of the deionized water to the total weight (g) of the sodium dodecyl sulfate, the ammonium persulfate and the AEO-9 is 20: 3;
(2) uniformly mixing methyl methacrylate, butyl acrylate and acrylic acid to obtain a solution B, wherein the volume ratio of methyl methacrylate to butyl acrylate to acrylic acid is 20: 10: 1;
(3) uniformly mixing azodiisobutyronitrile, hydroxylated multi-walled carbon nanotubes and deionized water to obtain a solution C, wherein the weight ratio of the azodiisobutyronitrile to the hydroxylated multi-walled carbon nanotubes is 1: 1, the ratio of the volume (mL) of the deionized water to the weight (g) of the hydroxylated multi-walled carbon nanotubes is 1: 16;
(4) dropwise adding the solution B and the solution C into the solution A through a peristaltic pump at the temperature of 80-90 ℃, continuing to keep the temperature and stir for reaction for 30-60min after dropwise adding, and adjusting the pH value to 7-8 by using ammonia water after the reaction is finished to obtain the modified acrylic polymer, wherein the volume ratio of the solution A, B, C is 2: 5: 4.
the cleaning agent has a good cleaning function, probably because the modified acrylic polymer can be cooperated with sodium dodecyl benzene sulfonate and an emulsifier in a system, the cleaning effect of the cleaning agent is improved, and the surface of the modified acrylic polymer has a micro-nano structure, and the hydrophobic micro-nano structure has good dirt adsorption function and can reduce the contact area between dirt on a hard floor and the hard floor, so that the dirt on the hard floor can be easily removed. The applicant has found that, surprisingly, after application of the cleaning agent of the invention, the hard floor also has a glossy water film, probably because, in the system of the invention, the synergistic effect of the modified acrylic polymer and the disodium edetate allows the modified acrylic polymer to form a temporary glossy water film on the hard floor, which is temporarily protective for the hard floor and can increase the gloss.
The addition amount of the modified acrylic polymer is 30-80% of the weight of the sodium alkyl benzene sulfonate.
Preferably, the modified acrylic polymer is added in an amount of 50 to 60% by weight based on the sodium alkylbenzenesulfonate.
The applicant researches and discovers that the cleaning effect of the cleaning agent is best when the weight of the modified acrylic polymer is 50-60% of the weight of the sodium alkyl benzene sulfonate. Probably, the synergistic effect with sodium dodecylbenzenesulfonate and emulsifier is best when the modified acrylic acid polymer is added in an amount of 50-60% by weight based on the weight of sodium alkylbenzenesulfonate.
The hard floor includes but is not limited to marble, polished tile, vitrified tile, terrazzo and other hard floors.
The second aspect of the present invention provides a method for preparing a novel alkaline hard floor cleaning agent, wherein the novel alkaline hard floor cleaning agent is prepared by the following process:
(1) weighing raw materials of the novel alkaline hard floor cleaning agent in corresponding parts by weight for later use;
(2) adding water into a reaction kettle, adding disodium ethylene diamine tetraacetate while stirring, then heating the reaction kettle to 45-55 ℃, adding liquid caustic soda and alkylbenzene sulfonic acid, stirring and reacting for 12-18min to ensure that the pH value of the system is 7-9, finally adding an emulsifier, mixing and stirring for 15-25 min;
