Problems solved by technology

However, traditional sanitary ware products are easy to get dirty and difficult to clean. New self-cleaning sanitary ware products are mostly prepared with super-hydrophilic materials as substrates or surface coating methods, which have poor oil resistance and short service life. and other shortcomings

Embodiment Construction

[0011] Under the processing conditions of hot pressing temperature of 190°C, hot pressing time of 10min and hot pressing pressure of 10MPa; cold pressing temperature of room temperature, cold pressing time of 10min and cold pressing pressure of 10MPa, the injection molding grade ultra-high molecular weight polyethylene The pellets are processed into plastic sheets of a certain size; then, under the condition of 120°C, using the excellent ductility of ultra-high molecular weight polyethylene, the plastic panel for sanitary ware is prepared by vacuum forming; a certain amount of hot xylene solvent (temperature (greater than 120°C) quickly etch the surface of the plastic panel three times (each treatment time is about 30s); after the surface etching treatment, take an appropriate amount of aqueous solution to rinse for 3-5 minutes until the excess solution on the surface is rinsed away.

[0012] Attached from the manual figure 1 It can be seen that the ultra-high molecular weight...

Abstract

The invention discloses a preparation method of a sanitary ware with a super-hydrophobicity surface, belonging to the field of surface modification of high polymer materials and polymer-based sanitary ware article materials. The invention comprises the following steps of firstly preparing a plastic plate with a certain size by using ultra high molecular weight polyethylene materials through press forming or extrusion forming, then carrying out heating treatment on the ultra high molecular weight polyethylene plate, carrying out vacuum suction moulding under the temperature of about 120 DEG C, and carrying out wind cooling shaping so as to enable the ultra high molecular weight polyethylene plate to become a household sanitary ware plastic panel. The sanitary ware panel after forming is treated three times by fast surface etching treatment by using hot solution including xylene through a physical method, and therefore, the material surface has larger static contact angle and also a smaller rolling angle so as to enable the sanitary ware material surface to display the effect of a water drop dripping on a lotus leaf, and the invention becomes the sanitary ware article materials with the super-hydrophobicity surface.

Description

technical field [0001] The invention relates to the preparation of ultra-high molecular weight polyethylene as a sanitary ware material and the surface etching treatment of the material, and belongs to the field of surface modification of polymer materials and polymer-based sanitary ware materials. Background technique [0002] It has long been a dream of people to obtain super-hydrophobic materials similar to lotus leaves. The so-called super-hydrophobic surface generally refers to the surface with a contact angle with water greater than 150°. It is difficult for water droplets to stay stably on this surface, which is related to water droplets. Many phenomena that people do not want to see, such as surface pollution, snow accumulation, oxidation, current conduction, and fluid viscosity, can be effectively contained. This new type of material will bring great benefits to people's daily life and industrial and agricultural production. Come to great convenience. But so far, o...
