Special antibacterial, anti-ageing and noise-reduction master batch for plastic shells of household appliances

Abstract

The invention discloses special antibacterial, anti-ageing and noise-reduction master batch for plastic shells of household appliances. The master batch disclosed by the invention is prepared from thefollowing raw materials in parts by weight: 85 to 100 parts of carrier resin, 10 to 20 parts of a pigment, 21 to 47 parts of modified ceramic micro-powder, 10 to 20 parts of an antibacterial agent and 0.5 to 2 parts of an anti-ageing agent. A preparation method of the master batch disclosed by the invention comprises the following steps: weighing all the raw materials according to the raw material ratio, and grinding and thinning; then adding the carrier resin and the anti-ageing agent into a high-speed mixing machine and uniformly mixing; finally, adding a mixed material into an internal mixer and mixing; extruding and drawing, and granulating. According to the special master batch for the plastic shells of the household appliances, the common carrier resin is adopted and is suitable forvarious plastic shells of the household appliances, and a compatibilizer is not needed; the special antibacterial, anti-ageing and noise-reduction master batch for the plastic shells of the householdappliances is prepared through simple operation; the master batch has antibacterial, water-repelling, anti-pollution and anti-ageing functions; the master batch is uniformly dispersed, has a consistent hue and is convenient to add and use; the master batch has the advantages of no toxin, high efficiency, long anti-pollution period and noise reduction.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a special antibacterial, anti-aging and noise-reducing masterbatch for plastic shells of household appliances. Background technique [0002] Regarding the hazards of home appliance noise, many people only think of hearing damage, but in fact this is only one aspect. Experts pointed out that the harm of noise is far more than damage to hearing, and it can also damage eyesight in severe cases. People who have been in a noisy environment for a long time are prone to eye fatigue, eye pain, vertigo and visual tears. The noise of home appliances will also affect people's normal work, study and rest. For a long time, the plastic casing of home appliances will also age due to light, the physical and mechanical properties will decrease, the surface will become dark, and due to the growth and accumulation of microorganisms, the surface will become dirty and mold will...
