Problems solved by technology

Disposable shoe covers and latex shoe covers are commonly used. The principle should be waterproof, anti-pollution, improving environmental quality, and controlling sanitary pollution; preventing pathogens from causing pollution. Shoe covers should have good waterproof performance and can be used in one time. Shoe covers should be worn in the specified area, and should be taken off in time when leaving the area. However, most of the existing shoe covers are troublesome to wear and affect the appearance. They cannot solve the problem of traditional overshoes, which are clumsy and difficult to carry. Disposable Polyethylene and other plastic shoe covers are not wear-resistant and durable, and such shoe covers are not dirt-resistant. During the wearing process, they will carry a lot of dust, which will affect the use effect and go against the original intention of using shoe covers. , those skilled in the art urgently need to develop a new method for preparing self-cleaning plastic shoe cover materials to meet higher requirements for use and market demand

Embodiment 1

[0019] The method for preparing wear-resistant and self-cleaning plastic shoe cover material specifically includes the following steps:

[0020] (1) Put the polyol mixture and catalyst into the reaction kettle, raise the temperature to 180°C, draw a vacuum while heating up, control the pressure in the reaction kettle to -0.1MPa and the temperature to 180°C for dehydration for 2h, then cool to 105°C and pass in Release the vacuum with nitrogen to obtain mixture A; heat the thiophosphoric acid tris(4-phenylisocyanate), cyclohexanedimethylene diisocyanate, and chain extender to 80°C and mix them with mixture A uniformly, and then pass the host speed 300r / min, melt pressure 0.2MPa, compression zone temperature 170°C, melting zone 175°C, metering zone 175°C twin-screw extruder reacts and extrudes to obtain polyurethane elastomer; the catalyst accounts for the total polyol mixture 0.5% by mass; the mass ratio of the thiophosphoric acid tris (4-phenyl isocyanate), cyclohexane dimethylen...

Embodiment 2

[0028] A preparation method of wear-resistant self-cleaning plastic shoe cover material specifically includes the following steps:

[0029] (1) Put the polyol mixture and catalyst into the reaction kettle, raise the temperature to 180°C, draw a vacuum while heating, control the pressure in the reaction kettle to -0.08MPa and the temperature to 160°C for dehydration for 0.5h, then cool to 95°C, pass Enter nitrogen to release the vacuum to obtain mixture A; heat the thiophosphoric acid tris(4-phenylisocyanate), cyclohexanedimethylene diisocyanate, and chain extender to 50°C and mix with mixture A uniformly, and then pass through the host A twin-screw extruder with a speed of 300r / min, a melt pressure of 0.2MPa, a compression section temperature of 175°C, a melting section of 180°C, and a metering section of 185°C reacted and extruded to obtain a polyurethane elastomer; the catalyst accounts for the proportion of the polyol mixture 0.01% of the total mass; the mass ratio of said thi...

Abstract

The invention belongs to the technical field of plastic processing, and particularly relates to a preparation method of a wear-resistant self-cleaning plastic shoe cover material. The shoe cover material prepared by the preparation method disclosed by the invention is light and flexible, is resistant to skid, dust and static electricity, and has a good self-cleaning function. Residues of water stain on the surface is avoided, and the shoe cover is dense, soft and comfortable, can be repeatedly washed and used, is easy to wash and dry, and can resist water and falling by 360 degrees. The texture is softer; toughness is higher; high-temperature resistance and abrasion resistance are achieved; and 100% water resistance and durability and wear resistance can be achieved. The surface of the material has a self-cleaning function and dirt resistance, the service performance of the shoe cover material is prolonged, and corrosion resistance of the material is good.

Description

Technical field [0001] The invention belongs to the technical field of plastic processing, in particular to a preparation method of wear-resistant self-cleaning plastic shoe cover material. Background technique [0002] Shoe covers, also called shoe covers, are derived from "mud-proof leggings" and are a protective cover for feet and ankles. They were originally used by soldiers and farmers in the 18th century to protect their boots and legs from mud. The mud-proof leggings are made of stiff cloth, and there are buckles or elastic bands under the shoes to tighten them from the side. By the 19th century, the strongest functionality evolved into shoe covers; the strongest ornamentation became shoe covers, and the neat and neat effect of white shoe covers on black shoes made the equipment worn on the feet a guard of honor and military uniforms. feature. Shoe covers, also known as shoe covers, are commonly used dust-proof protection products to facilitate guests without taking off ...
