Description

A kind of easy scouring toy resin containing nano powder

Technical field

The present invention relates to toy technique field, more particularly to a kind of easy scouring toy resin containing nano powder.

Background technology

Toy is that especially children play the product of happy game for people.In ancient Egypt's historical relic away from modern about more than 5000 years There is the doll made by material such as clay, timber, beast bone and ivory, there is small-sized kitchenware and life appliance in children grave.Away from the present about Find there is the pull toy for dividing into circle wheel in the Persian historical relic of 3000.Sound-emitting top and animal that the useful cotton rope of ancient Greek is started The toy of image.Be unearthed the movable ivory carving portrait of four limbs in ancient Roman's mausoleum.18 th Century German Nuremburges become European toy The production center.Doll adopts stamping process, vivo devices mechanical part, the action such as can perform crying, walk.Also been produced music Toy and winding-up toy etc..19th century, scientific and technical New TownMovement was applied to toy designs and production, the development for promoting toy to produce, The optical toys such as appearance activity picture, raree show, magic lantern.American scientist T.A. Edison in 1878 is made using gramophone and can be said Words, the doll sung.The nineties in 19th century, the U.S. produces electronic small fan and the electronic mini train of rail in succession.Chinese toy Also there is long history.Find there is small-sized pottery pig away from modern about 5500 Shandong Ningyang Dawenkou ruins.Away from about 3800 the presents Also there are ceramic toy and jingle bell in Qijia culture remains.Kite and ball game also have the history of more than 2000.Diabolo, wind Car, rolling ring, seven-piece puzzle, Chinese puzzle ring etc. become the folk toys of Chinese tradition, and after 20th century, toy manufacturing industry becomes important Industry.The German Toy production thirties and outlet occupy first place in the world.The forties, toy production in the U.S.'s was developed rapidly, is produced, is consumed With the hat that import leaps to the world.The fifties, Japan's toy industry emerged, and export amount catches up with Germany.Chinese toy industry at the end of the fifties Formed, with Beijing, Shanghai as major production areas.Toy kind is up to kind more than 7000.The sixties Hong Kong Toy industry rise, the eighties with Afterwards Taiwan toy industry has very big development.

Current China is toy big producing country, and the toy of global 70-80% is by domestic product.With China market Constantly improve and specification, add inclination of the country in policy to toy, animation, game etc. " creative industry " and help energetically Hold, domestic toy industry will be lifted into a unprecedented golden period, trend pickup, industry benefit.

Children are the main consumer groups of toy, and underproof toy material can endanger the healthy and life peace of children Entirely.The main component of plastics is synthetic resin.Resin accounts for the 40-100% of plastics gross weight.The key property of plastics is mainly determined Also play an important role due to the person's character of resin, but additive.However, existing plastic toys performance is not good, it is impossible to meet day The market demand that benefit increases.

The B of patent CN 103965576, a kind of antibiotic toy plastics, it is compounded using ABS and PVC, and a kind of antibacterial modeling is obtained Expect that, for toy, PVC material Long-Time Service is dangerous, have potential hazard to the health of children, and the antiseptic for using is pure Chemical antiseptic, inadequate environmental protection, it is therefore desirable to a kind of toy resin of more environmental protection safety..

The content of the invention

The object of the invention is exactly to make up the defect of prior art, there is provided a kind of easy scouring toy containing nano powder is used Resin.

The present invention is achieved by the following technical solutions：

A kind of easy scouring toy resin containing nano powder, it is obtained by the raw material of following weight parts：ABS60-80, February Cinnamic acid dioctyltin 0.1-0.3, stearic acid 0.3-0.6, phenol-formaldehyde resin powder 0.7-1, polyvinyl acetate emulsion 0.2-0.4, Huang Beeswax 1-3, palm wax 1-2, dialdehyde starch 1-3, nanomete talc powder 1-2, absolute ethyl alcohol 3-6, silane coupler kh550 0.3- 0.5th, zinc stearate 2-4, calcium carbonate superfine powder 0.5-0.7, corncob load anti-biotic material 1-3, irgasfos 168 0.1-0.2；

Described corncob load anti-biotic material is obtained by the raw material of following weight parts：Linseed oil 0.1-0.2, APG 0.1-0.3, lecithin 0.1-0.2, citric acid 0.01-0.04, shitosan 1-2, polyglycol ether 0.3-0.4, irgasfos 168 0.1-0.2, corncob 2-4, silver nitrate 0.2-0.5.

A kind of described easy scouring toy resin containing nano powder, preparation method is comprised the following steps：

（1）Prepare corncob load anti-biotic material；

Described corncob loads the preparation method of anti-biotic material：

Add water in corncob equivalent to the water of 0.8-1.5 times of above-mentioned raw materials, after mixing, anaerobic fermentation is cleaned after 1-2 days, is air-dried, It is dried, then steam blasting is carried out to it, explosion water vapour pressure is 0.05-0.3Mpa, and blasting time is 1-3s, produces thing Jing and take off It is dried after water process, obtains xeraphium standby；Citric acid adds suitable quantity of water, after being configured to the citric acid solution that concentration is 2-5%, adds Xeraphium, after stirring 0.5-1h at 40-60 DEG C, adds remaining needed for silver nitrate and corncob load anti-biotic material preparation Raw material, after stirring, filters, and with distillation water washing filter residue, to filtrate in neutrality, filter residue is added into concentration for the carbonic acid of 1-2% In hydrogen sodium solution, 1-2h is stirred at 30-50 DEG C, filtered, with distillation water washing filter residue, to filtrate in neutrality, filter residue is in 60-80 After being dried at DEG C, corncob load anti-biotic material is obtained final product standby；

（2）After absolute ethyl alcohol, silane coupler kh530 stir, polyvinyl acetate emulsion, nanomete talc powder, ultrasound are added After concussion 1-2h, drying obtains modified powder standby；

（3）Pour Bis(lauroyloxy)dioctyltin, stearic acid, phenol-formaldehyde resin powder, cera flava, palm wax, dialdehyde starch into reaction In kettle, with rotating speed, 500-800 rev/min is stirred mixing 5-10 minutes, adds modified powder, irgasfos 168, corncob and bears Carry anti-biotic material and remaining raw material, 700-900 rev/min be well mixed after send into screw extruder melting mixing；

(4) screw speed is 300-400rpm, after extruding pelletization, is obtained final product.

It is an advantage of the invention that：（1）Rationally, materials safety has no toxic side effect inventive formulation, with the addition of corncob, becomes useless For treasured, environmental protection and energy saving green non-pollution.With the addition of modified Nano powder so that resulting materials hole is few, refuses oil, easily clean.It is yellow Beeswax, palm wax increased the compatibility of the present invention.

（2）Present invention adds corncob load antibacterial powder, bio-carrier can load antiseptic, slow to discharge, antibacterial Effect is strong, and lasting effect is good, have broad spectrum activity and good advantage compatible with fabricated product, all has to various bacteriums, mould fine Killing inhibitory action, to environment without any pollution.Make use of corncob as bio-carrier, turn waste into wealth.The present invention is adopted Steam explosion technology, the acute expansion of the gas in hole, produces " explosion " effect, is fiber fines by raw material tear, by increasing capacitance it is possible to increase raw The load capacity of thing carrier.

（3）It is modified to compounding powder using coupling agent, the intensity of raw material is increased while the compatibility for increasing raw material And impact resistance, the service life using the toy of the resin manufacture can be effectively improved.
