Washing-free ultraviolet curing coating and preparation method thereof

Abstract

The invention discloses a washing-free ultraviolet curing coating, which is prepared from the following raw materials in parts by weight: 80 to 100 parts of composite emulsion, 5 to 8 parts of cleaning filler, 5 to 8 parts of repairing filler, 1 part of dispersing agent, 1 part of cross-linking agent and 1 to 3 parts of photoinitiator, The invention further discloses a preparation method of the washing-free ultraviolet curing coating, wherein titanium dioxide and cuprous oxide are utilized for complementary advantages, the cleaning filler is prepared, the cleaning filler not only has an excellent photocatalytic self-cleaning effect, but also has multiple antibacterial and mildew-proof effects, and the repairing filler contains disulfide bonds which can be self-repaired through light reversibility, when the coating has scratches and cracks, the coating can be self-healed under the action of ultraviolet light and heat energy, nano silicon dioxide and silane contain Si-O-Si structures, methyl and silicon atoms form side groups, the volume of silicon-oxygen bonds in a main chain is large, the cohesive energy density is low, and the coating has good weather resistance, thermal stability, wear resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of paint preparation, and in particular relates to a no-clean ultraviolet curing paint and a preparation method thereof. Background technique [0002] In daily life, clothes will inevitably be stained with oil, coffee, dust and other stains. These stains not only affect the normal use of clothes, but also provide a breeding environment for microorganisms. Therefore, with the acceleration of the pace of life and the pursuit of high-quality life, people's growing demand for high standards and more requirements for knitted clothing More new clothing requirements, functional knitting, and the development and application of fabrics are currently a research hotspot in the knitting industry. For example, most of the knitted thermal underwear in winter are heavy and difficult to clean. Repeated washing will cause loss of wearing performance and the underwear is worn next to the body. It is very easy to breed bacter...

Problems solved by technology

However, due to the nano-TiO 2 The light absorption range and catalytic efficiency are not ideal enough, nano-TiO 2 The interaction between particles and fabrics is poor, and the nanoparticles are easy to fall off and other factors. So far, there is no mature photocatalytic disposable fabric on the market. Studies have found that the lotus leaf has a super-hydrophobic non-cleaning effect because there are many micron-sized particles on its surface. The protrusions, and there are nano-scale fluff on the micro-scale protrusions, when the rain falls on the surface of the lotus leaf, water droplets will be formed without infiltrating the surface. This is the "super-hydrophobic effect of the lotus leaf"
