Problems solved by technology

[0006] The technical problem to be solved by the present invention: Aiming at the disadvantages that most of the wiping materials are hydrophilic and oleophobic, the removal rate of oil stains is poor, the oil holding capacity is low, the decontamination ability is weak, and the cleaning of oil stains is not thorough, a high-staining oil stain is provided. The preparation method of wiping material, the present invention first utilizes citric acid, triethylene glycol monobutyl ester and p-toluenesulfonic acid as raw material to prepare transparent liquid, soaks pure cotton cloth in transparent liquid, can change the structure of pure cotton cloth Carry out modification to enhance the oil absorption and oil holding capacity of cotton fiber, and then use the sol obtained after hydrolysis of ethyl orthosilicate to further modify the pure cotton fabric to make the pure cotton fiber have strong lipophilic properties , the high-sodium oil stain wiping material prepared by the present invention has low cost, simple process, strong oil absorption, high oil holding capacity, can quickly absorb oil products, and has wide application prospects in the fields of machine oil wiping, oil-water separation, etc.

Abstract

The invention relates to a high oil-receiving wiping material capable of quickly absorbing an oil product, and belongs to the technical field of wiping material preparation. Transparent liquid is prepared from raw materials namely citric acid, triethylene glycol monobutyl ester and p-toluenesulfonic acid, pure cotton woven fabric is immersed in the transparent liquid, the structure of the pure cotton woven fabric can be modified to enhance the oil absorption and oil receiving capacities of cotton fiber, the pure cotton woven fabric is further lipophilically modified by using sol obtained afterhydrolysis of ethyl orthosilicate, and the pure cotton fiber has strong lipophilic property. The high oil-receiving wiping material prepared in the invention has low cost, simple process, strong oilabsorption, and high oil receiving amount, can quickly absorb the oil product, and can be widely used in the field of machine oil wipe, oil and water separation, etc.

Description

technical field [0001] The invention relates to a high-sodium oil stain wiping material, which belongs to the technical field of wiping material preparation. Background technique [0002] A high-performance cleaning cloth should be able to effectively remove dust, oil and watermarks without damaging the surface of the object being wiped. dust [0003] It is the primary goal of cleaning, and oil stains are unavoidable on instruments, meters, machine tool surfaces, home kitchens, etc., so cleaning cloths are required to have a good degreasing effect. Ordinary cleaning cloths have good liquid absorption properties, and related scholars have found that the water absorption of microfiber fabrics is much higher than the oil absorption. When dealing with oil stains, water molecules may occupy most of the space, and a small amount of oil remains on the surface of the cloth. The phenomenon of wiping the surface of objects. If the cleaning cloth can absorb the oil, then disposing o...
