4) reinforcing agent the preparation method comprises the following steps: according to weight ratio, take 8~10 parts of ethyl orthosilicates and deionized water according to The ratio of 1:8-10 mixes, then sequentially adds 1~2 part of sepiolite cashmere, the glacial acetic acid of ethyl orthosilicate weight 10% and just thereto The carbon dust of silester weight 5%, which is uniformly mixed, to be reacted, and in reaction process, applies frequency into reaction system every 20min The ultrasonic wave 1min of 250-270kHz obtains solid powder to carry out ultrafiltration to reaction system after reaction, finally by solid Powder abundant calcination under aerobic conditions removes carbon dust and obtains reinforcing agent；

Four) it is kneaded and prepares high-elastic plastics

5) nitrocellulose plastics, the epoxy resin fused matter of step 1 preparation, adjacent benzene are weighed respectively according to the ratio Compound fibre prepared by dioctyl phthalate di-n-octyl, polytetrafluoroethylene (PTFE), polymethyl siloxane, the reinforcing agent of step 3 preparation and step 2 Silk is tieed up, then melts nitrocellulose plastic melt and epoxy resin fused matter respectively, then by di-n-octyl phthalate, poly- Methylsiloxane and polytetrafluoroethylene (PTFE) are added sequentially in the nitrocellulose plastics melted, and mixing under the conditions of 220-240 DEG C Reinforcing agent is finally added thereto and stirs evenly by 30min, spare；

6) composite fibre silk is uniformly mixed with the epoxy resin fused matter of thawing, it is close then adds it to step 5) again Getting the product is stirred evenly in mixture after refining.

English words mother tuber of the invention can also be theoretically made of any material, it is preferable that using high-elastic plastics Package iron plate is made；Since high-elastic plastics are then melted by adding epoxy resin wherein based on nitrocellulose plastics Object, polytetrafluoroethylene (PTFE), di-n-octyl phthalate, polymethyl siloxane, reinforcing agent and composite fibre silk are closed, so that its Elasticity, toughness and wearability are enhanced, and its brittleness then reduces accordingly；

Contain polymethyl siloxane and polytetrafluoroethylene (PTFE) in high-elastic plastics, its toughness and resistance to can be promoted to a certain extent Mill property, and be added and be made of glass fiber, carbon fiber, polyacrylonitrile fibre, Fypro and dibenzoic diglycol laurate Composite fibre silk, these fibers be kneaded when can not only be cross-linked with each other, to prevent the brittle fracture of material, and compound The dibenzoic diglycol laurate contained in fiber filament can not only further enhance the plasticity and toughness of material as plasticizer, more These fiber filaments can be made to combine closely with basis material；

The reinforcing agent of high-elastic plastics is made of sepiolite cashmere and ethyl orthosilicate, so that plastics are with excellent Wear-resisting and corrosion resistance, when preparing reinforcing agent, since sepiolite cashmere has very big internal surface area, under ultrasonic wave effect The structure of a part of sepiolite cashmere can be destroyed, so that the silica for generating teos hydrolysis enters directly into Hai Pao Inside aminanthine, so as to improve the surface characteristic of silica and the physical property of sepiolite cashmere, in this way as reinforcing agent When being kneaded with remaining component, can sufficiently it combine, to increase substantially the wear-resisting and corrosion resistance of plastics.

For the performance for further increasing high-elastic plastics, modified meerschaum suede is contained in high-elastic plastics additive of the invention Powder, nano aluminium oxide micro mist, both substances are dispersed in plastics when can be kneaded under the auxiliary of sodium carboxymethylcellulose In, on the one hand, modified meerschaum suede powder has very big internal surface area, is the micro mist with microcellular structure, these micropore knots On the other hand the external force that structure effectively can be cut down and absorb is the surfaces externally and internally for making modified meerschaum suede powder in modifying process Both it is grafted a large amount of silicone hydroxyl, these groups are connected modified meerschaum suede powder with matrix by chemically reacting, guarantee With good interface binding power；

And epoxy resin fused matter is made of three kinds of epoxy resin, modified manometer silicon dioxide and modified silicasol, not only Have both the characteristic of three kinds of epoxy resin, and the modified manometer silicon dioxide wherein contained is in the preparation, using barium hydroxide and Sodium carbonate mixing is as catalyst by nanoscale SiO₂It the surface of particle can be by the effect of hydroxyl, thus containing certain The oxygen-containing functional group of quantity increases nanoscale SiO₂The related surface compatability of particle, in nanoscale SiO₂Particle and remaining original When material is sufficiently mixed, because of SiO₂Particle very little, and large specific surface area, the structure of imperceptibility make contact of the rest materials with it Area increases, and makes SiO₂Particle can be evenly dispersed in material, consequently facilitating SiO₂Chemistry occurs at high temperature with remaining substance Bonding or physical bond.In addition, evenly dispersed nanoscale SiO₂It is equivalent to " anchor point ", can make to generate under hot environment Reinforcing matrix it is in connection, in the case where being acted on by external impacts, the effect of " stress concentration " can be generated, so that around it Some matrixes " surrender " and absorb more work of deformation, furthermore can also generate " pinning-is climbed up and over " effect, increase crackle and exist Suffered resistance when extension consumes work of deformation, so that its toughness be made to increase；Moreover, because joined modified silicasol particle And modified manometer silicon dioxide, the mechanical property and thermal property of material can be substantially improved, while also found modified silicasol The addition of particle is equal to the raising of the tensile property of component mixing, product in preparation process and the final interpenetrating form of product Favorably.

Beneficial effect, compared with prior art, the present invention has the advantage that

1) for the present invention by the way that viewing area is arranged at the top of substrate, then surface, which is sticked, with elevating mechanism the square of picture It shapes flitch and is moved to viewing area, user spells out in the English words mother tuber of the spelling words portion special construction on substrate top With English word corresponding to content on picture, to realize the teaching objective taught through lively activities；And in spelling words portion bottom With magnet strip, so that so that the English words mother tuber with iron plate is adsorbed on the cardboard on surface spells composition word；

2) English words mother tuber of the invention is made of special elastoplastic cladding iron plate, compares more existing material, Its elasticity, wearability, toughness and anti-brittle failure are improved, and are not easy to be damaged by children when in use, and feel is more It is soft.
