Problems solved by technology

Many students write and draw on the desktop intentionally or unconsciously. Most of the ink stains are difficult to clean, which not only affects the appearance, but also affects the learning environment. Ink seeping into the desktop will also corrode and damage the desktop, affecting the service life of the desk.
[0003] At present, anti-graffiti coatings in the domestic market are mainly divided into fluororesin coatings and silicone resin coatings. Fluoropolymers are expensive and costly to apply. After long-chain siloxane resins are modified and cross-linked, their coatings can approach those of fluororesin coatings. The performance of the layer, and the price is much lower than that of fluororesin
Acrylic resin or epoxy, polyester resin and other anti-graffiti coatings have certain corrosion resistance to strong chemical cleaning agents, and can withstand several chemical cleaning agent cleanings, but eventually need to be replaced by new coatings

Embodiment Construction

[0029] Specific embodiments of the present invention such as Figure 1-2 As shown, a kind of anti-graffiti desk, comprises table leg 1 and table board 2, and described table board 2 is made of particleboard 21, and table board 2 is coated with wood grain decorative layer 22, wear-resistant layer 23 and anti-graffiti Layer 24, the wear-resistant layer 23 is polyurethane, and the anti-graffiti layer 24 includes polysilazane, hydroxyl-terminated polydimethylsiloxane, silica nanoparticles modified by silane coupling agent, surface active agent, crosslinking agent, catalyst and dispersant. The anti-graffiti layer 24 has scratch resistance, high chemical resistance, corrosion resistance, temperature stability, easy cleaning and barrier effect, even if the surface layer anti-graffiti layer 24 is damaged, the wear-resistant layer 23 of the bottom layer can still protect the wooden surface. The tabletop acts as a protection.

[0030] The amount of the above-mentioned polysilazane is ...

Abstract

The invention relates to the field of teaching equipment, and particularly discloses an anti-doodling desk, which comprises desk legs and a desk board, wherein the desk board is made of a shaving board, and is coated with a wood grain decorative layer, a wear-resistant layer and an anti-doodling layer, the wear-resistant layer is made of polyurethane, and the anti-doodling layer comprises polysilazane, hydroxyl-terminated polydimethylsiloxane, silica nanoparticles modified by a silane coupling agent, a surfactant, a cross-linking agent, a catalyst and a dispersing agent. By the adoption of thescheme, traces left when students paint and draw disorderly on the desk surface can be effectively prevented, even if the left marks can be scrubbed off easily, maintenance is easy, cost is saved, and the desk is attractive and durable.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a desk with an anti-graffiti function. Background technique [0002] Graffiti is a major public nuisance of modern human civilization. The loss caused by graffiti has attracted more and more people's attention, and the cost of removing graffiti in various countries is huge. In schools, the situation of graffiti on desks and chairs is not optimistic. Desks and desktops are generally wooden tabletops, wood and other porous materials, and writing ink is easy to penetrate, so it is difficult to remove graffiti from such substrates. And many students will write and draw on the desktop intentionally or unconsciously. Most of the ink stains are difficult to clean, which not only affects the appearance, but also affects the learning environment. [0003] At present, anti-graffiti coatings in the domestic market are mainly divided into fluororesin coatings and silicone resin c...
