Problems solved by technology

[0003] At present, there are mainly two preparation methods for antibacterial toilet lids. The first is to spray antibacterial agents on the surface of the toilet lid, and then bake the surface at a high temperature of 200-250 degrees Celsius to form an antibacterial agent on the surface of the toilet lid. The problem with this method is that high-temperature baking accelerates the aging rate of the toilet cover and reduces the service life of the toilet cover. The second method is to add antibacterial agents to the raw materials for preparing the toilet cover. The main purpose of this method is to The problem is that the antibacterial agent is diluted by the raw material. Since the toilet lid has a certain thickness, most of the antibacterial agent is still inside the toilet lid, while the surface is less, resulting in most of the antibacterial agent in the toilet lid. Cannot exert antibacterial effect , resulting in a great waste of antibacterial agents

Abstract

The invention relates to an antibacterial and antiviral toilet lid and a preparation method thereof. The antibacterial and antiviral toilet lid is prepared from the following components in parts by weight: 60-70 parts of a resin material, 10-20 parts of a flame-retardant filler, 1.0-5.0 parts of a dispersing agent, 1.0-2.0 parts of an antioxidant and 0.5-1.0 part of a modified antibacterial and antiviral treatment agent, wherein the modified antibacterial and antiviral treatment agent adopts an organic silicon modified photocatalyst, and the organic silicon modified photocatalyst is obtained by modifying an inorganic photocatalyst antibacterial agent with an organic silicon release agent. In addition, the invention also discloses a preparation method of the antibacterial and antiviral toilet lid. On the premise of ensuring the antibacterial, antiviral and anti-mite effects of the toilet lid, the use amount of the antibacterial agent is greatly reduced.

Description

technical field [0001] The invention belongs to the field of sanitary ware, and in particular relates to an antibacterial and antiviral toilet seat and a preparation method. Background technique [0002] Toilets are closely related to people's lives and bring us great convenience. However, due to the environmental impact of toilets, especially in public areas, there are often various tiny microorganisms that cannot be seen by naked eyes on toilet lids and gaskets. According to the survey of relevant public health authorities, it is found that 32% of the toilet lids and toilet gaskets have Shigella bacteria, and some can even survive on the toilet seat for as long as 17 days; Take it to a height of 6 meters, and suspend it for several hours, and then fall on the bathroom wall, toothbrush, mouthwash cup and towel, making it polluted by bacteria and viruses, especially when someone in the family is sick, causing disease Bacteria will increase hundreds of times, seriously endan...
