Description
Technical field
The present invention relates to toy for children field, more particularly to a kind of strong durability plasticine.
Background technology
Plasticine is the material that children use when manufacturing products of craftsmanship, and is that the intelligence development class that a kind of depth is liked by teenager is played
Tool, formability thereof preferably to fabricate various moulding, the recreational imagination that can usually give full play to children of plasticine,
Its colourful inner world is showed, and to the hand brain eye coordinate culture of children, and color recognition and creation thought ability side
Also there is the educational effect of uniqueness in face.
Many kinds of plasticine in the prior art be present, generally well-known handicraft with plasticine be in order that children easily
Manufacture products of craftsmanship and manufactured, when making keeping after moulding, some plasticine can intactly keep its model
Shape, but hard plasticine causes children to be difficult with the plasticine to make model.Some plasticine are because easily mediating
The characteristics of and be conveniently used for playing for children, but its moisture is more, therefore adhesion phenomenon is serious when making, and causes user
The species and shape for the moulding that can be moulded also are restricted, and the phenomenon for shrinking and deforming after the drying, therefore are made
Into moulding be difficult preservation, poor durability.In addition, being shelved for a long time after the artifacts made, can hold because of moisture evaporation
Easily it is hardened, therefore can not reuses.

As a further improvement on the present invention, strong durability plasticine preparation method is as follows：
Step 1: after peach gum is ground into powder, 100 mesh sieve are crossed, peach gum powder is obtained, is subsequently placed in 60 DEG C of vacuum drying ovens
Drying；
Step 2: after PEO and water are mixed, it is heated with stirring to form lotion at a temperature of 85-90 DEG C；
Step 3: the baking obtained by modified starch, maleic acid rosin ester, rosin, guar gum and step 1 is added while hot
Dry peach gum powder, temperature is risen to 160 DEG C, melt blending 10-30min is carried out under stirring condition, obtains blend；
Step 4: blend is cooled into room temperature, add maltitol, wetting agent, natural plant pigment, erucyl amide,
Preservative, antioxidant, and stir；
Step 5: being eventually adding cenosphere, and stir.
As a further improvement on the present invention, the pretreatment to peach gum is also included in the step 1：
5g original peach gums are cleaned, after going the removal of impurity, powder is ground into and crosses 100 mesh sieve, soaked with 200g clear water
24-48h, it is fully swelled, then break into pulpous state, then it is 9-11 to adjust its pH value with 1mol/L aqueous slkali, is put into high pressure
Infusion 2-8h is stirred in reactor at 90-100 DEG C, decolorization is carried out to it with decolorising agent；Peach gum hydrolysate is passed through again
After cationic ion-exchange resin, efflux is concentrated, is dehydrated, is subsequently placed in 60 DEG C of vacuum drying ovens and dries.
As a further improvement on the present invention, the specific preparation process of the modified starch is as follows：
(1) 20-30g starch is taken, adds 35-50g, concentration 0.05-1.00mol/L, pH value 3.5-4.5 citric acid-lemon
Lemon acid sodium cushioning liquid, is warming up to 40 DEG C -50 DEG C, stirs；
(2) 0.2-0.5g carbohydrase is added, the constant temperature stirring enzymolysis 20- under conditions of 40 DEG C -50 DEG C, pH value 3.5-4.5
28h；

One or more in carboxylic acid sodium.
The present invention strong durability plasticine, using peach gum, PEO, modified starch and maleic acid rosin ester as
Main component, peach gum are advantageous to produce the plasticine of various different colours, and stable performance, polycyclic oxygen as a kind of transparent material
Ethane can be used for the plasticity for adjusting peach gum, form plasticity feel, modified starch is suitable mainly as adhesive and stabilizer
Butene dioic acid rosin ester is used for the soft durometer for adjusting plasticine, makes feel more preferable, makes plasticine not easy to stick on hand, adds maltose
Alcohol can make natural plant pigment be easier to be combined with peach gum, even if peach gum is easier to paint, while maltitol also has guarantor
It is moist, make moisture in plasticine be not easy to evaporate, plasticine can be made to keep soft, cenosphere can make plasticine dried
Being not easy to shrink or rupture in journey, adding rosin can make plasticine have more preferable toughness and elastic force, and wetting agent is to plasticine
Moisture retention can play good effect, prevent that plasticine is dry and cracked, guar gum has good emulsification thickening characteristic and stably
Film forming characteristics, can in stable plasticine natural plant pigment vividness, moreover it is possible to prevent that pigment contamination is arrived in use
On skin, erucyl amide can make plasticine have a smooth feel, and skin contact is more comfortable.The strong durability rubber of the present invention
Mud, the phenomenon for being not susceptible to shrink and deforming after drying, manufactured moulding is easy to maintain, durability is strong.
