Abstract
The invention discloses a cleaning agent, a preparation method and application thereof, and belongs to the technical field of cleaning agents. The cleaning agent comprises the following components in parts by weight: 500 parts of water; 5-30 parts of a high-molecular anionic surfactant; 25-90 parts of a nonionic surfactant; 10-20 parts of alkaline protease; 10-20 parts of lipase; 5-10 parts of zinc-containing deodorant; wherein the pH value of the cleaning agent is 8-12; the weight ratio of the high-molecular anionic surfactant to the nonionic surfactant is 1: (1 to 7.5). The cleaning agent disclosed by the invention effectively improves the cleaning power of the cleaning agent on HDPE plastics through the synergistic effect of the surfactant, the enzyme and the deodorant, can powerfully remove oil stains diffused into the HDPE material, and can remove residual peculiar smell of the HDPE material.
Description
Technical Field
The invention relates to the technical field of cleaning agents, and particularly relates to a cleaning agent and a preparation method and application thereof.
Background
High Density Polyethylene (HDPE) bottles are widely used in dairy drink packaging, and in recent years, people have more and more dairy drinks, and accordingly, the amount of HDPE drink bottles discarded is increased. Along with the implementation of national sustainable development strategy, the call for environmental protection and resource recycling is higher and higher, and people pay more and more attention to the recycling of numerous waste HDPE beverage bottles. The HDPE bottle is difficult to degrade, has higher economic value for HDPE regeneration and recovery, and can reduce the influence of waste on the environment. The surface of the prior HDPE beverage bottle discarded after consumption can be stained and adsorbed with a large amount of stains such as oil stain, silt and the like, and the surface stains need to be removed by cleaning for further recycling.
Because the HDPE bottle has higher adsorption capacity on oil stain substances, oil stain can even permeate into the HDPE surface layer to form a swelling layer, so that the oil stain is not easy to elute from the HDPE bottle surface, and residual oil stain can also generate certain peculiar smell; in addition, part of dairy products in HDPE beverage bottles usually remain, and bacteria can grow to generate peculiar smell after long-time fermentation.
The prior art discloses a general cleaning agent which can be used for cleaning stains on the surface of plastics by using a plurality of components such as sodium dodecyl benzene sulfonate and fatty alcohol-polyoxyethylene ether. However, the cleaning agent can only clean pollutants on the surface of the HDPE material, but is difficult to remove oil stains diffused into the HDPE material, and residual peculiar smell on the HDPE material cannot be completely removed.
Disclosure of Invention
The invention aims to solve the technical problems that the existing cleaning agent is poor in cleaning of oil stains diffused into an HDPE material and residual odor of the HDPE material, and provides the cleaning agent.
The invention also aims to provide application of the cleaning agent in cleaning waste high-density polyethylene materials.
The above purpose of the invention is realized by the following technical scheme:
the cleaning agent comprises the following components in parts by weight:
wherein the pH value of the cleaning agent is 8-12;
the weight ratio of the high-molecular anionic surfactant to the nonionic surfactant is 1: (1 to 7.5).
Wherein, it is required to be noted that:
the cleaning agent disclosed by the invention effectively improves the cleaning power of the cleaning agent on HDPE plastics through the synergistic effect of the compounded surfactant, the enzyme and the deodorant, can powerfully remove oil stains diffused into HDPE materials, and can remove residual peculiar smell of the HDPE materials.
The action mechanism of each component of the cleaning agent is as follows:
in the cleaning agent, aiming at the surface characteristics of the HDPE material, the high molecular anionic surfactant is adopted, and compared with a small molecular anionic polymer, the high molecular anionic surfactant has better affinity with the HDPE surface, is favorable for dispersing and adsorbing more dirt and reducing foam, and is favorable for cleaning the oil dirt diffused into the HDPE material.
The cleaning agent disclosed by the invention is used for compounding the specific high-molecular anionic surfactant and the nonionic surfactant according to a proportion aiming at the surface characteristics of HDPE materials, particularly the strong adsorption effect on greasy dirt stains, so that the critical micelle concentration of the surfactants can be reduced, the surface tension of a cleaning water solution is lower, the two surfactants are matched to form a mixed micelle, the wrapping and elution effects on the greasy dirt are increased, the stains such as greasy dirt, silt and the like attached to the surface of the HDPE material can be well removed, and the high-molecular anionic surfactant and the nonionic surfactant in a specific proportion can clean the greasy dirt diffused into the HDPE material without losing the surface of the HDPE material.
Under the condition that the pH value of the cleaning agent is alkaline, partial oil stains can be saponified and dissolved, the decontamination effect of the surfactant can be better exerted, and the damage to HDPE is small.
The cleaning agent disclosed by the invention is compounded with the selected surfactant under the condition of pH of 8-12, so that the activity of enzyme preparations such as alkaline protease and lipase is not influenced, and the odor caused by fermentation of dairy products is reduced by decomposing stains such as protein and fat in residual dairy products through two enzyme preparations. The zinc atoms in the zinc-containing deodorant can form strong chemical bonds with nitrogen atoms and sulfur atoms in odor molecules generated after decomposition of proteins, fats and the like, so that the odor is thoroughly eliminated, and the residual odor of the HDPE material can be eliminated.
The pH value can be adjusted by one or a mixture of sodium hydroxide, potassium hydroxide or sodium carbonate.
In order to further improve the cleaning capability of the cleaning agent on the oil stain diffused into the HDPE material, the weight ratio of the high molecular anionic surfactant to the nonionic surfactant is preferably 1: (3-5).
In order to further remove the residual odor of the HDPE material, the zinc-containing odor removing agent is preferably zinc phenolsulfonate.
Zinc atoms in the zinc phenolsulfonate can form strong chemical bonds with nitrogen and sulfur atoms in odor molecules so as to thoroughly eliminate odor, and thus residual odor of HDPE materials is effectively eliminated.
Preferably, the high molecular anionic surfactant is polyacrylamide.
The polyacrylamide has good water-solubility effect and strong adsorption effect, and is favorable for further improving the removal capacity of the oil stain.
In order to further improve the saponification effect of the oil stain and improve the activity of the alkaline protease, the pH value is preferably 9-11.
Preferably, the odor adsorbent further comprises an odor adsorbent, and the pore diameter of the odor adsorbent is 0.3-0.5 nm.
The odor adsorbent adsorbs odor micromolecules which are decomposed and fall off during cleaning, has a good odor removing effect, and also has the effects of softening water quality, promoting emulsification and dispersion and preventing dirt from redepositing.
The pore diameter of the odor adsorbent is 0.3-0.5nm, which is beneficial to adsorbing small molecular substances generated after the dairy products are decomposed by alkaline protease and/or lipase, thereby reducing the odor.
Preferably, the odor adsorbent is a zeolite.
Preferably, the hydrogen peroxide also comprises 5-30 parts of hydrogen peroxide.
The hydrogen peroxide has a bactericidal effect, can prevent the propagation of bacteria on the surface of the HDPE material, and further prevents the odor generated by the decomposition of the dairy products by the bacteria.
