Description

Technical Field

[0001] The invention belongs to the technical field of cleaning agent preparation, and in particular relates to an environment-friendly cotton picker spindle cleaning agent composition, and also relates to a preparation method of the environment-friendly cotton picker spindle cleaning agent composition. Background Art

[0002] Xinjiang is one of the three major cotton-producing areas in my country, and mechanized cotton picking has been widely used for many years. In the mechanized cotton picking process, cotton picker spindle cleaning agent is one of the key consumable cleaning and lubrication products to ensure the continuous and normal operation of the cotton picker during the cotton picking season. Through field research, it was found that the John Deere brand cotton picker spindle cleaning agent used by John Deere Company of the United States for its cotton pickers is the best-reputed cleaning agent product in the local area.

[0003] The cotton picker picks cotton through the spindles, and the cotton must also be smoothly separated from the spindles. This requires the use of cleaning agents to ensure that the spindles are clean, tidy, and smooth, and to clean and remove dust, plant juice, and excess grease from the spindles. The spindles are constantly rubbing against cotton branches and cotton in a high-temperature environment. The high temperature is prone to serious accidents in this industry - cotton catching fire, which requires cleaning agents to provide a good cooling effect for the spindles. It can be seen that the performance of the cotton picker spindle cleaning agent is a key factor affecting whether the cotton picker can work smoothly. This is also the main reason why cotton pickers pay attention to and feedback that John Deere's cleaning agent is better.

[0004] At present, domestic cotton picker spindle cleaning agents are generally emulsified products, which are formulated with base oil, emulsifier and various additives. The performance focuses on emulsification stability, cleaning, corrosion resistance and wear resistance. In terms of product raw material selection, most people pay attention to the use effect, and rarely mention the impact of the product discharged into the cotton field on the soil.

[0005] A Chinese patent (publication number: CN 101838593A) discloses a cotton picker spindle cleaning liquid, including 70-90% mineral oil, 3-20 non-ionic surfactants and rust inhibitors. Among them, the non-ionic emulsifier uses a nonylphenol polyoxyethylene ether series. Such products have biological toxicity and have been banned in many domestic application fields. In addition, mineral oil spilled in the soil is difficult to decompose, causing soil and water pollution. From an environmental protection perspective, it is not suitable for use in cotton fields. A Chinese patent (publication number: CN 116218584A) discloses a cotton picker spindle cleaning liquid, including 70-90% mineral oil, 0.3-2% sodium lauryl sulfate, 4-9% alkylphenol polyoxyethylene ether, and 6-9% polyol ester. This product still uses base oil and alkylphenol polyoxyethylene ether emulsifier, which has many disadvantages to soil, water and even human health from an environmental protection perspective. A Chinese patent (publication number: CN109705961A) discloses a cotton picker cleaning agent composition, including 4-12% fatty alcohol polyoxyethylene ether, 0.5-7% polyol ester, 0.01-1% solubilizing agent, 0.01-1% solubilizing agent and the balance base oil. Although the emulsifier of this product only uses the more environmentally friendly fatty alcohol polyoxyethylene ether, the base oil uses Karamay hydrogenated base oil, which is a mineral oil that is difficult to degrade. Therefore, it still has an adverse effect on the soil environment and does not belong to an environmentally friendly product. A Chinese patent (publication number: CN104178287A) discloses a cotton picker cleaning agent composition, including emulsifiers such as a mixture of fatty acid ester ethoxylate, fatty alcohol polyoxyethylene ether and alkyl ethylenediamine triacetic acid, vegetable oil, epoxidized vegetable oil and biodiesel, as well as rust inhibitors and wear reducers. Although this product has done a lot of work on base oil and emulsifier additives from an environmental perspective, it still uses conventional chemical emulsifier products and alkyl ethylenediamine triacetic acid, the most commonly used surfactant in laundry detergent, in the emulsifier system. Such substances are still difficult to decompose when they are spilled in cotton fields, especially because of the antibacterial properties of alkyl ethylenediamine triacetic acid, which is not conducive to biological decomposition.

[0006] Since cotton picker spindle cleaning agents have very strict requirements on the performance of their base oils, surfactants, and lubricants, they are not only required to have the cleaning, lubrication, cooling, and rust prevention properties of the product itself, but more attention should be paid to the environmental performance of the product. Currently, domestic cleaning agents are difficult to meet the requirements of using environmentally friendly raw materials for all components. Summary of the invention

[0007] The purpose of the present invention is to provide an environmentally friendly cotton picker spindle cleaning agent composition, which has excellent cleaning, cooling and lubricating effects and has a biodegradability of more than 90%.

DETAILED DESCRIPTION

[0018] The present invention is described in detail below in conjunction with specific implementation modes.

[0019] The environmentally friendly cotton picker spindle cleaning agent composition of the present invention comprises the following components in terms of mass percentage: 10-20% of a composite emulsifier, 5-10% of a lubricant, 1-3% of a coupling agent, and the remainder is base oil, and the sum of the mass percentages of the above components is 100%.

[0020] The composite emulsifier is alkoxylated plant polyphenols with different alkoxy numbers;

[0021] Alkoxylated plant polyphenols are prepared by reacting plant polyphenols, which are derived from natural plants and have a biodegradability of more than 90%, with ethylene oxide copolymers; alkoxylated plant polyphenols with different alkoxy numbers are plant polyphenols with different numbers of linked ethylene oxide structures.

[0022] Alkoxylated plant polyphenols have good biodegradability and can minimize soil pollution in cotton fields.

[0023] The lubricant is any one or more of oleic acid, linoleic acid, oleyl alcohol, linoleyl alcohol, lauryl alcohol, tetradecanol, and hexadecanol;

[0024] The coupling agent is any one or more of ethanol, glycerol, and ethylene glycol;

[0025] The base oil is vegetable oil, and the vegetable oil is any one or more of peanut oil, soybean oil, palm oil, rapeseed oil, and biodiesel;

[0026] The lubricant and coupling agent used in the present invention are derived from natural plants and animals or decomposition products of plants and animals, and are natural and environmentally friendly. The base oil completely abandons mineral oil and adopts bio-oil ester, which has the outstanding advantage of fast degradation in the cotton field and can also serve as a nutrient component for plant growth.

[0027] The preparation method of the environmentally friendly cotton picker spindle cleaning agent composition of the present invention is specifically as follows:

[0028] Put the base oil in a reaction kettle, heat it to 40°C-60°C, add the lubricant, and stir for 1-2 hours; stop heating, add the composite emulsifier, continue stirring for 2-3 hours until it is completely dissolved, then add the coupling agent, in a transparent state, filter and fill through a 200-500 mesh filter at room temperature to obtain a cotton picker spindle cleaning agent composition.

[0029] Example 1

[0030] Add 73.5 g of peanut oil into a beaker, and then add 16.5 g of alkoxylated plant polyphenols, 2.2 g of oleic acid, 3.3 g of ethanol, 2.8 g of oleyl alcohol and 1.7 g of glycerol in sequence under stirring at room temperature, and stir until uniform and transparent to obtain a cotton picker spindle cleaning agent composition.

[0031] Example 2

[0032] Add 80.5 g soybean oil into a beaker, and then add 12.5 g alkoxylated plant polyphenols, 2.3 g linoleic acid, 1.6 g ethylene glycol, 2.5 g linoleyl alcohol and 0.6 g glycerin in sequence under stirring at room temperature, and stir until uniform and transparent to obtain a cotton picker spindle cleaning agent composition.

[0033] Example 3

[0034] Add 43.5 g peanut oil and 40.5 g soybean oil into a beaker, and then add 10.5 g alkoxylated plant polyphenols, 1.7 g oleic acid, 1.6 g lauryl alcohol and 2.2 g glycerin in sequence under stirring at room temperature, and stir until uniform and transparent to obtain a cotton picker spindle cleaning agent composition.

[0035] Example 4

[0036] 77.5 g of rapeseed oil was added to a beaker, and 12.5 g of alkoxylated plant polyphenols, 3.2 g of linoleic acid, 3.1 g of ethanol, 2.8 g of lauryl alcohol and 0.9 g of glycerol were added in sequence under stirring at room temperature, and stirred until uniform and transparent to obtain a cotton picker spindle cleaning agent composition.

[0037] The cotton picker spindle cleaning agent composition prepared in Example 1 was tested for performance with other similar products (the imported product is the cotton picker spindle cleaning agent of John Deere Company of the United States, and the domestic product is the local brand of Xinjiang Kerun, also named cotton picker spindle cleaning agent). As can be seen from Table 1, the general physical and chemical indicators of different products are not very different, and although there are differences in viscosity and flash point, they are not directly related to the performance. The key performance lies in the lubrication performance of the product, the 2% dilution PB value, and the average biodegradation percentage. These two indicators are directly related to the lubrication performance of the product on the spindle and the impact on the soil environment of the cotton field. The composition of the present invention is significantly better than similar products on the market. Especially from the perspective of environmental protection, the average biodegradation percentage of the composition of the present invention reaches more than 90%, which is difficult to match by other products.
