Description
Technical field
The invention belongs to polymeric material field, relate to a kind of material that is used for toilet lid and packing ring and preparation method thereof.
Background technology
The world organizes in the lavatory promoter Mr. Jack to think and along with the development of human civilization history, goes to toilet " yardstick that the lavatory is human civilization " and experienced from the field to indoor, from squatting just to toilet seat.Toilet as one of greatest invention of 19th century, once brought great convenience, especially women, pregnant woman, obesity, old weakling to people's life.But the very little mikrobe that all has our naked eyes to see on toilet lid and the packing ring.Find on 32% toilet lid and the toilet seat dysentery bacterium is arranged according to relevant public health authoritative department investigation.Pollute so serious place exactly with contact " intimately " of people's skin; Therefore want emphasis to clean; Often can water and clean with hydrochloric clear lavatory liquid, and, also can use harder toilet brush or steel wire lump etc. with wipings such as thimerosal and liquid detergents; Therefore require toilet lid and the gasket materials must water-fast, corrosion-resistant, scrape resistant, preferably have the antibiotic self-cleaning performance.And the development that the intelligent closestool of controlling along with computer covers also requires toilet lid to have flame retardant properties.
The material of toilet lid and packing ring generally has plastics, urea-formaldehyde resin, wooden, bamboo matter and stone material etc., because the back three belongs to the resource-type goods and materials, and cannot say for sure to support or too heavy, and that uses now is fewer and feweri.The advantage of urea-formaldehyde resin is that texture is good, and the hardness height is sturdy and durable, be difficult for scratching, but urea-formaldehyde resin is a thermosetting material, should not recycle, and meets strong acid, the easy decomposition of highly basic, and electrical property and weathering resistance are relatively poor.
The plastics toilet lid is Vestolen PP 7052 PP (Polypropylene), acrylonitrile-butadiene-styrene copolymer ABS (Acrylonitrile Butadiene Styrene) and acrylic polymetylmethacrylate (PolymethylMethacrylate) commonly used etc. generally.Acrylic is the type material preferably that after pottery, can make sanitary ware.Acrylic has good toughness, and cracky be prone to cleaning and characteristics such as quality is soft, but the acrylic board surface hardness is low, is scratched easily, and its winter hardiness is not relatively poor yet, and about 9.2 ℃ of embrittlement temperature, and be easy to burn has limited oxygen index only 17.3.ABS hardness is big, scrape resistant and not yielding, but easy to change, easy fracture, anti-aging poor, resistance to elevated temperatures is poor, corrosion-resistant.Not easy to change, the fracture of PP material, resistance to elevated temperatures is good, and erosion resistance is strong, water-tolerant, but hardness is not enough, and the production difficulty is big.Though scrape resistant PP is also arranged at present, because the scratch resistance liniment is prone to separate out, the goods taste of getting is bigger.
Summary of the invention
The object of the invention is exactly for material that a kind of good flame resistance, scrape resistant, antimicrobial toilet lid and packing ring are provided and preparation method thereof, and the resistant of high or low temperature of this material and electrical property are all very excellent.
Principle of the present invention is in polyamide (PA), to add an amount of PP to form the PA/PP alloy, and the adding of PP has improved the easy water-absorbent of PA, and gives material toughness preferably, and alloy itself has kept outstanding scratch resistance of PA and electrical property.In this alloy, add flame retardant filler, can make material reach the flame retardant properties of V-2 to V-0 on the one hand, these fillers also can improve the scraping and wiping resistance performance of goods on the other hand.The interpolation of antiseptic-germicide can obviously improve the anti-microbial property of material, improves the automatically cleaning ability of toilet lid and packing ring.The master metal of inorganic fungicide commonly used will be a main raw material with silver, zinc, copper etc., is that carrier is processed with the mineral filler.Cupric ion has color, and with influencing the attractive in appearance of product, zinc has certain bacterinertness, but its antibacterial strength is merely 1/1000 of silver ions, so this patent has been selected silver-series antibacterial agent.
The object of the invention can be realized through following technical scheme:
