Description

Technical Field

[0001] The invention belongs to the field of sanitary materials, and in particular relates to a photocurable hydrophobic material and a preparation method thereof. Technical Background

[0002] With the continuous growth of my country's economic strength and the improvement of people's living standards, consumers have raised their demands for bathroom products from appearance design, structure and function to artistry, intelligence, simplicity, energy saving, functionality, etc. Bathroom products such as faucets, pendants, showers, floor drains, etc. are frequently exposed to water, oil smoke, dust, etc. during use, and are prone to water stains and oil stains that are difficult to clean. Over time, they seriously affect their appearance and service life, which is also a major user pain point that needs to be solved urgently.

[0003] At present, bathroom materials, such as ceramic tiles, are waterproofed mainly by hydrophobic siloxanes that are hydrolyzed at high temperatures to form a hydrophobic coating, but the hydrophobic effect is not good enough. At the same time, high-temperature treatment conditions are not suitable for some heat-sensitive bathroom materials. In addition, high-temperature heating consumes a lot of energy, which does not meet the requirements of energy conservation and environmental protection. It is urgent to use a green and environmentally friendly technology to efficiently prepare hydrophobic materials for bathrooms. Photocuring technology is an efficient, environmentally friendly, energy-saving, and high-quality surface treatment technology, and is known as a new technology for green industry in the 21st century. Moreover, it is photocured at room temperature, and there is no requirement for the heat resistance of the material, so it is an ideal preparation method for bathroom materials.

[0004] Patent CN115448596B invented a zirconia-based bathroom ceramic and its preparation method, zirconia @ MoS2 core-shell particles, kaolin, potassium feldspar, sodium feldspar, nano titanium dioxide, dolomite, zinc oxide, aluminum oxide, hafnium nitride, metal powder ball milling and mixing evenly, and then mixed with organic silicon polymer, organic polyzirconium precursor, POSS sol, ethylene glycol, water to obtain glaze, the glaze is applied to the surface of the body by high pressure glaze spraying process, and fired, the firing temperature is 1180-1250℃, the firing time is 50-90min. Traditional bathroom products in the bathroom are mainly made of ceramics, marble and other materials, which have the disadvantages of high production cost, cumbersome process, complex process, low yield, etc. Bathroom products made of polymer materials can solve the above problems very well, so bathtubs and wash basins made of polymer materials have been widely used. Patent CN112430372A invented a polymer material for bathroom. The invention adopts polymer resin, aggregate as the polymer material skeleton, and filler as filler, so that the polymer material has strong support performance and improves the physical properties of the polymer material. The overall material of this method is composed of polymer materials. Through testing, it is found that its wear resistance is improved compared with commercially available bathroom materials. The only drawback is that injection molding also requires high temperature conditions and high energy consumption, which is not suitable for heat-sensitive polymer materials.
