Abstract
The invention discloses broad-spectrum antimicrobial fragrant polypropylene resin for a washing machine. The resin is prepared from the following raw materials in percentage by weight: 60-84 percent of polypropylene, 0.2-1 percent of small molecule organic antibacterial agent, 0.2-1 percent of inorganic antimicrobial agent, 0.1-1 percent of freshener, 10-30 percent of glass fiber, 5-10 percent of compatilizer, 0.1-2 percent of dispersing agent and 0.1-1 percent of antioxygen. The invention further provides a preparation method of the broad-spectrum antimicrobial fragrant polypropylene resin for the washing machine. The broad-spectrum antimicrobial fragrant polypropylene resin for the washing machine has a broad-spectrum, efficient and lasting antibacterial function, and is higher in safety; washing machine water stirring blades or an washing machine inner barrel made of the resin provide clothing with specific fragrance; as the adding of the glass fibers, the resin has a stronger comprehensive mechanical property, and has low probability of deformation in the using process; the preparation process of the resin is simple, convenient, clean and efficient.
Description
Technical field
The present invention relates to the polymer modification technical field, specifically, is a kind of use in washing machine broad-spectrum antimicrobial delicate fragrance acrylic resin and preparation method thereof.
Background technology
Polypropylene (Polypropylene, be called for short PP) as one of five large general-purpose plastics, have that density is little, production cost is low, comprehensive mechanical property is good, nontoxic, corrosion-resistant, be easy to the advantages such as processing and recovery, be widely used in various fields, as household electrical appliance, inner and outer decorative parts of automobile, body-building apparatus, office appliance, daily necessities, toy and sanitary ware etc.Polypropylene articles is exposed, and its surface can grow a large amount of thalline in bacterium, mould space, and people's health in serious harm.Along with scientific and technical progress and Economic development, the raising of people to healthy and environmental consciousness, recognize that gradually polypropylene itself does not possess anti-microbial effect.Therefore, exploitation has the Novel polypropylene material of antibacterial, can kill within a certain period of time mould, the bacterium of product surface or suppress its breeding, avoid by the polypropylene material material products, occurring between person to person, thing and thing, people and thing the cross infection of mould, bacterium, reduce transmission of disease, environmental protection cause and people healthy had to very important realistic meaning.Simultaneously can in the antibacterial polypropylene resin, add aromatic according to people's hobby, the washing machine parts prepared with this antibiotic delicate fragrance acrylic resin is with light delicate fragrance, and this have broad-spectrum antimicrobial delicate fragrance washing machine and be subject to increasing welcome.
At present, about polyacrylic development and application be mainly by the antiseptic-germicide physical blending in polypropylene PP resin.Chinese patent application: (1), publication number are the patent of invention of CN 102336958 A, a kind of flame-retardant antibacterial transparent polypropylene material and preparation method thereof is disclosed, adopt the method for fire retardant and the composite use of antiseptic-germicide to make the polypropylene material of preparation have simultaneously fire-retardant and anti-microbial effect, the density of being fuming during the product burning is very low, and the while is not easy to change, cost is low; (2), publication number is the patent of invention of CN 102140199 A, a kind of preparation method of Novel polypropylene antibacterial matrices is disclosed, the nanometer silver powder is distributed in the solvent of nonpolar or low-pole, then add polypropylene chip and make its dissolving, by the thermal backflow technology, remove desolventizing, after drying, pulverize, finally by Screw Extrusion, prepare polypropylene antibacterial master batch; (3), publication number is the patent of invention of CN 102424709 A, a kind of antibacterial polypropylene material and preparation method thereof is disclosed, polypropylene, white oil, antiseptic-germicide, lubricant, oxidation inhibitor are mixed, join in twin screw extruder and melt extrude granulation, the anti-biotic material of preparation contains antiseptic-germicide, good anti-bacterial effect is antibiotic lasting and mechanical property is excellent; (4), publication number is the patent of invention of CN 102558676 A, discloses a kind of high antibiotic polypropylene composite material and preparation method thereof, first to nano-TiO
2Particle carries out doping treatment and obtains dopen Nano TiO
2Particle, then obtain modification TiO through coupling agent treatment
2Particle, further by modified Nano TiO
2Particle and polypropylene fusion are extruded and are made high antibiotic polypropylene composite material; (5), publication number is the patent of invention of CN 101818834 A, a kind of nanometer antibacterial polypropylene pipe material and preparation method thereof is disclosed, by 1%～15% of polypropylene weight, the nano-class antibacterial masterbatch is added in acrylic resin, with stirrer, mix, carry out the melting heating, obtain the mixture of the acrylic plastering of nano-antibacterial master batch, for the preparation of the nano-antibacterial internal layer; Then the acrylic plastering that makes to contain nano-antibacterial is synchronizeed co-extrusion with common plastics, make the tubing that comprises the outer and nano-antibacterial internal layer of acrylic plastering, finally finalizes the design cooling.
